AI Browser Market Intelligence Report
12/30/2025
Starting Week 47, this report shifts to a hybrid publishing model to better match market maturity. Weekly briefings cover strategic developments, lawsuit updates, product launches, and security incidents. Monthly deep dives (published when market data accumulates or significant shifts occur) include full adoption metrics updates with refreshed visualizations and platform cards. The agentic browser market has transitioned from explosive growth phase (Weeks 40-43) to litigation and consolidation phase—strategic intelligence and legal developments now drive the narrative.
Week 52 Strategic Briefing Summary
Week 52 ended the seven-week data drought with two hard metrics while year-end retrospectives positioned "agentic" as the defining term for 2025's AI evolution.
📊 Market Data Returns: First Data in Seven Weeks: Week 52 delivered two hard data points after seven consecutive weeks without metrics. Perplexity disclosed usage statistics and Chrome market share data emerged. Ends longest data drought since tracking began. Eight weeks of market size estimates built on assumptions without validation finally resolved.
📈 Year-End Framing: "Agentic" as 2025's Defining Term: Multiple year-end retrospectives positioned "agentic" as the word capturing 2025's AI evolution. Business Standard: "How agentic AI quietly took over phones, PCs and browsers." ETC Journal: "One Word That Captures AI in 2025: 'Agentic.'" NH Register: "AI agents arrived in 2025." Industry narrative shifted from "smarter chatbots" to "proactive AI systems" with agentic browsers as consumer manifestation.
📊 Market Data: Norton Neo adoption metrics not disclosed. PayPal Instant Buy transaction volumes unavailable. Opera Neon user numbers remain undisclosed. No comprehensive market share data from analytics firms. Week 52 data points break drought but don't provide competitive landscape visibility.
🎯 Week 52 Analysis:
Data Drought Resolution: Seven weeks without hard metrics (Weeks 45-51) resolved with Week 52's two data points. Market size estimates had reached eight layers of assumptions: 60-125M North American users extrapolated from Week 44's Cyberhaven enterprise study (27.7% Atlas installation rate) without validation. Week 52 data provides first validation checkpoint in nearly two months, allowing recalibration of growth estimates that had become increasingly speculative.
The "Agentic" Reframing: Year-end retrospectives positioned agentic browsers not as isolated product category but as consumer-facing manifestation of broader "agentic AI" shift. Narrative evolution: reactive chatbots (2023) → multimodal assistants (2024) → proactive agents (2025). Agentic browsers reframed as interface layer for AI systems that initiate actions rather than wait for commands. Elevates category significance beyond "new browser type" to "fundamental interaction model change."
The Three-Phase Pattern: Q4 2025 retrospective reveals three distinct phases. Phase 1 (Weeks 40-42): Explosive announcements, constraint removal, estimated 400-500% growth, optimistic "Third Browser Wars" narrative. Phase 2 (Weeks 43-46): Security crisis, legal battles, enterprise blocking recommendations, growth deceleration. Phase 3 (Weeks 47-52): Maturation, commerce partnerships, security acceptance, "agentic" framing. Market compressed full technology adoption cycle into 13 weeks.
Perplexity's Litigation Burden: Six active lawsuits by Week 52: Amazon (commerce), NYT + Chicago Tribune + Reddit + Encyclopedia Britannica + Dow Jones (content). Perplexity emerged as primary litigation target while competitors (OpenAI Atlas, Norton Neo, Opera Neon) face minimal legal pressure. Suggests Perplexity's aggressive content aggregation strategy created disproportionate liability exposure. Other players may benefit from Perplexity absorbing legal precedent-setting risk.
Enterprise Adoption Paradox Unresolved: Week 44 showed 27.7% enterprise Atlas installation in nine days. Week 46 brought IT professional blocking recommendations. Week 51 delivered industry consensus: "Block. Not 'evaluate carefully.' Block." Week 52 provides no enterprise follow-up data. Cannot determine whether enterprises implemented blocking guidance or continued adoption despite security warnings. Enterprise market remains highest uncertainty variable: critical for TAM estimates but zero visibility.
Security Acceptance Posture Solidified: OpenAI's Week 51 admission that prompt injection is "unlikely to ever be fully solved" combined with Week 51 academic study finding 30 vulnerabilities across 8 platforms established new industry baseline. Week 52 retrospectives incorporated security limitations as permanent market characteristic rather than temporary challenge. Market shifted from "security will be fixed" to "security will be managed." Acceptance replaces remediation as dominant posture.
The Measurement Infrastructure Failure: Only 3 data weeks in 13 weeks (23%). Average 0.38 hard data points per week. Private companies (Perplexity, OpenAI, Norton, Opera) released zero user metrics voluntarily. No analytics firm published comprehensive market share data. Third-party studies rare (Cyberhaven enterprise, Human Security Black Friday, Week 52 data points). Market grew rapidly but remained opaque: qualitative development visible, quantitative measurement absent.
The Pattern: Seven-week data drought ends with two metrics, year-end retrospectives elevate "agentic" to defining 2025 term, Perplexity faces six lawsuits while competitors avoid legal exposure, enterprise adoption remains unmeasured despite blocking recommendations, and security acceptance replaces security promises. Week 52 closes 2025 with market maturation visible but market size unknowable.
2025 Year-End Retrospective: The Agentic Browser Market
Thirteen weeks. Three data points. Six lawsuits. Zero transparency.
The North American agentic browser market in 2025 delivered the technology industry's defining paradox: explosive product velocity with near-zero measurement infrastructure. From Week 40's Perplexity Comet launch through Week 52's year-end retrospectives, the market demonstrated what happens when big tech races to ship consumer AI products faster than analytics firms can track adoption.
The Three Acts of Q4 2025
Act I: Explosion (Weeks 40-42) October brought constraint removal at unprecedented pace. Perplexity Comet launched at $200/month (Week 40), dropped to free (Week 40), added $5/month Plus tier (Week 42), then made Plus free globally (Week 42): four pricing changes in three weeks. Platform expansion matched pricing velocity: Mac → Windows → Android rollout compressed into 14 days. Google shipped Gemini in Chrome to general availability. Dia Browser launched on Mac. Estimated 400-500% growth over three weeks. Week 44's Cyberhaven study captured the explosion: 27.7% of enterprises installed OpenAI Atlas within nine days of launch. Market sentiment: optimistic, high-velocity, "Third Browser Wars" narrative dominated.
Act II: Crisis & Consolidation (Weeks 43-46) Security vulnerabilities exposed industry-wide. OpenAI Atlas launched Week 43 immediately followed by security researcher demonstrations of prompt injection attacks. Perplexity responded Week 44 with Privacy Snapshot feature. Amazon sued Perplexity Week 46. IT Brew published enterprise blocking recommendations same week: "Block. Not 'evaluate carefully.' Block." Growth decelerated from 150% → 50% → 25% week-over-week as security concerns dominated. Data drought began: seven consecutive weeks without hard metrics. Market sentiment shifted: cautious, security-focused, trust concerns.
Act III: Maturation & Reckoning (Weeks 47-52) Commerce partnerships emerged (PayPal + Perplexity Week 47). Norton entered market Week 48 with explicit security-first positioning. Week 51 brought the reckoning: OpenAI admitted prompt injection is "unlikely to ever be fully solved." Academic study identified 30 vulnerabilities across 8 major platforms. Week 52 year-end retrospectives positioned "agentic" as 2025's defining term. Market sentiment: realistic, security-aware, long-term focused. Qualitative evolution clear, quantitative data absent.
The Data Availability Crisis
The numbers tell the transparency story:
- 13 weeks tracked (Weeks 40-52)
- 3 hard data weeks (23%)
- 0.38 average data points per week
- 7-week maximum data drought (Weeks 45-51)
- 8 layers of extrapolation by Week 52
Week 44's Cyberhaven enterprise study provided the only comprehensive adoption data: 27.7% of surveyed enterprises installed Atlas in nine days. Week 49 offered two marginal metrics: Comet reached 1M Android downloads, Human Security reported 144.7% Black Friday AI agent traffic surge. Week 52 ended the drought with two data points. Between these three weeks: nothing. No player released user metrics voluntarily. No analytics firm published market share data. No follow-up enterprise studies.
Market size estimates became exponentially unreliable:
- Week 44: 20-45M NA users (based on Cyberhaven)
- Week 45: 25-55M (1 assumption layer)
- Week 46: 30-65M (2 layers)
- Week 47: 35-75M (3 layers)
- Week 48: 40-85M (4 layers)
- Week 49: 45-95M (5 layers)
- Week 50: 50-105M (6 layers)
- Week 51: 55-115M (7 layers)
- Week 52: 60-125M (8 layers)
By year-end, estimates ranged from 60M to 125M North American users: a 108% uncertainty band built on eight weeks of compounded assumptions. Not market intelligence. Market speculation.
Competitive Landscape: The Big Tech Lockout
Market entry compressed into 13 weeks:
Pre-Week 40: Fellou CE (freemium, early 2025), Opera Neon (invite-only, September 2025)
Weeks 40-42: Perplexity Comet (free, October 2), Google Chrome Gemini (free, October 3), Dia Browser (Mac, October 9)
Weeks 43-46: OpenAI Atlas (free, October 21)
Weeks 47-52: Norton Neo (free, December 2)
The pattern: Big Tech owns the free mass market. Perplexity, Google, and OpenAI control zero-cost consumer access. Independent players (Opera Neon $19.99/month, Dia Browser $20/month) relegated to premium specialist niches. Fellou CE's freemium model bridges both. Norton's late entry (Week 48) with security-first positioning targets enterprises spooked by Week 46 blocking recommendations. But by Week 52: no user metrics disclosed by any player. Cannot determine whether Norton's security messaging resonates, whether premium pricing limits Opera/Dia adoption, whether Google's Chrome integration drives Gemini usage. Market structure visible. Market share invisible.
The Legal Reckoning: Perplexity's Six Lawsuits
Timeline of litigation escalation:
Week 45 (Nov 10): Amazon cease-and-desist to Perplexity Week 46 (Nov 17): Amazon formally SUES Perplexity Week 50 (Dec 15): NYT sues Perplexity
By Week 52, Perplexity faces six active lawsuits:
- Amazon (commerce/scraping)
- New York Times (content/copyright)
- Chicago Tribune (content/copyright)
- Reddit (content/copyright)
- Encyclopedia Britannica (content/copyright)
- Dow Jones (content/copyright)
Perplexity emerged as agentic browser industry's litigation magnet. Five content lawsuits from major publishers. One commerce lawsuit from e-commerce giant. Legal framework forming through Perplexity-specific precedents while competitors (OpenAI, Google, Norton, Opera) face minimal direct legal pressure. Two interpretations: (1) Perplexity's aggressive content aggregation strategy created disproportionate liability exposure, or (2) Perplexity absorbs legal precedent-setting risk allowing competitors to adjust strategies based on rulings. Either way: Perplexity shoulders industry's legal burden while market share distribution remains unknown.
Security: From Promises to Acceptance
The security posture evolution:
October (Weeks 40-43): "We'll fix it" Vulnerabilities discovered. Reactive patches. "Move fast" ethos dominant.
November (Weeks 44-46): "We're working on it" Proactive features (Privacy Snapshot). Enterprise concerns elevated. IT blocking recommendations published.
December (Weeks 47-52): "We'll manage it" OpenAI admits "unlikely to ever be fully solved." Academic study confirms systemic vulnerabilities. Industry consensus: accept architectural limitations, implement risk management.
The Week 51 turning point: OpenAI's public admission that prompt injection attacks represent fundamental architectural challenge, not temporary bug. Academic researchers validated: 30 vulnerabilities across 8 platforms, at least one in every product tested. Categories: architecture flaws, unsafe site handling, cross-site tracking, personal data disclosure, session management. Not implementation quality issues. Structural design limitations.
Enterprise response: Week 44 showed 27.7% adoption in nine days. Week 46 brought blocking recommendations. Week 51 solidified consensus: "Block. Not 'evaluate carefully.' Block." But Week 52 provides no follow-up enterprise data. Cannot determine whether enterprises implemented blocking, continued adoption despite warnings, or implemented selective policies. Enterprise market (potentially largest TAM segment) remains highest uncertainty variable.
The "Agentic" Framing: From Feature to Paradigm
Week 52 year-end retrospectives positioned "agentic" as 2025's defining term. Not just browsers. Entire AI interaction model evolution:
2023: Reactive chatbots (respond to queries) 2024: Multimodal assistants (process text/image/voice) 2025: Proactive agents (initiate actions without prompting)
Agentic browsers reframed as consumer-facing interface for this paradigm shift. Business Standard: "How agentic AI quietly took over phones, PCs and browsers." ETC Journal: "One Word That Captures AI in 2025: 'Agentic.'" NH Register: "AI agents arrived in 2025."
Elevates category significance. Not "new browser type." Not "AI-powered Chrome extension." Fundamental interaction model change from human-initiated commands to AI-anticipated needs. Positions agentic browsers alongside enterprise AI agents, autonomous vehicles, robotics (all part of broader shift from reactive to proactive AI systems).
Strategic implication: expands addressable market beyond "people who want better browsers" to "anyone who uses AI systems." Raises stakes. But also raises expectations. Proactive AI requires trust. Trust requires transparency. Transparency requires data disclosure. Data disclosure remains absent.
What 2025 Revealed
About the market:
- Constraint removal drives explosive adoption (free pricing triggered 400-500% growth estimate)
- Security is architecturally unsolved (prompt injection fundamental challenge)
- Big Tech dominates mass market (Google, OpenAI, Perplexity control free access)
- Legal framework forming through Perplexity litigation (6 lawsuits in 3 months)
- Enterprise adoption paradoxical (27.7% installed Atlas despite security concerns, then blocking recommendations followed)
About data availability:
- Private companies don't share metrics voluntarily (zero user data disclosed)
- Third-party data extremely rare (3 data weeks in 13 weeks)
- Extrapolation becomes exponentially unreliable (8 assumption layers by Week 52)
- Qualitative developments far exceed quantitative measurement (high announcement velocity, near-zero data velocity)
- Market exists and grows but remains fundamentally opaque
About technology adoption cycles:
- AI products compress traditional adoption curves (full cycle in 13 weeks)
- Product launches precede measurement infrastructure (ship first, measure never)
- Security concerns emerge mid-adoption not pre-launch (Week 43, after 400-500% growth)
- Legal frameworks lag far behind market formation (first lawsuit Week 45, five weeks post-Comet launch)
- Industry narratives shift faster than consumer behavior (three distinct phases in one quarter)
2026: The Year of Measurement?
Expected Q1 2026 developments:
- CES 2026 announcements (January 7-10)
- Lawsuit discoveries and potential early rulings
- Enterprise policy changes (new fiscal year, security reviews)
- Possible year-end/Q4 2025 user data releases
- Security patches or acceptance solidification
Key questions for 2026:
- Will any player voluntarily release user metrics?
- Will Amazon lawsuit set commerce precedent affecting all agentic browsers?
- Will enterprises implement blocking or continue adoption?
- Will security improve meaningfully or stagnate at "managed risk"?
- Will independent players (Opera, Dia, Fellou) gain share or Big Tech consolidate further?
- Will analytics firms build agentic browser measurement infrastructure?
- Will "agentic" expand beyond AI community into mainstream vocabulary?
The definitive cadence decision: Weekly reporting in 2025 proved unsustainable. 0.38 data points per week average. Seven-week maximum drought. Eight layers of extrapolation. Market evolved rapidly but remained unmeasurable.
2026 reporting structure:
- Bi-weekly cadence as baseline (every two weeks)
- Weekly resumption threshold: 3+ hard data points in single week, verified user metrics from 2+ major players, major market event with measurable impact, analytics firm comprehensive report, or enterprise adoption follow-up study
- Event-driven deep dives: Lawsuit rulings, regulatory actions, major partnerships with disclosed metrics
The 2025 Verdict
The North American agentic browser market in 2025 delivered the startup adage "move fast and break things" at unprecedented scale. Products launched. Pricing collapsed. Platforms proliferated. Security vulnerabilities exposed. Lawsuits filed. Enterprises installed then considered blocking. OpenAI admitted architectural unsolvability. Year-end retrospectives declared "agentic" the defining term.
And through it all: near-zero data transparency.
2025 was the year agentic browsers arrived. 2026 will determine whether the market becomes measurable. The technology exists. The adoption likely accelerated. The legal framework is forming. The security risks are acknowledged.
But we still don't know how many people use these products.
Final assessment: The agentic browser market is real, growing, and important. It's also opaque, unmeasured, and fundamentally unknowable with current data availability. 2026's challenge isn't whether agentic browsers will succeed (they already have). It's whether the industry will build measurement infrastructure allowing anyone to track that success with confidence.
Until then: high conviction on market existence, low conviction on market size. Welcome to the age of agentic AI, where development velocity far exceeds measurement velocity, and year-end retrospectives must conclude with uncertainty bands wider than the estimates themselves.
Why We're Tracking This
When we said we were going all in on the retrieval layer, we meant it. Our work in Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), and modern SEO services already has us tracking AI referral traffic from chat interfaces—helping businesses figure out where their mystery clicks are coming from.
Now we’re taking it further. We’re documenting the emergence of agentic browsers from the very beginning. Will this become the next big shift in how people browse the web?

Commerce Wars Erupt: Amazon Blocks Perplexity as Security Responses Stall
Week Ending November 10, 2025: The battleground shifted from browser features to platform access as Amazon sent a cease-and-desist to Perplexity (Nov 4), demanding Comet stop making purchases on Amazon.com. This "battle for the future of commerce" marks the first major legal conflict in agentic browsers. Google expanded Chrome AI Mode to 160 countries (iOS/Android), Perplexity launched a reimagined Comet Assistant (23% better, multi-tab), and Atlas reportedly began Windows rollout. Despite Week 44's validated security crisis, responses were minimal—only Perplexity has shipped security features. Market now at 25-55M NA users with decelerating but steady growth.
- 🌍 Google Chrome + Gemini: GLOBAL EXPANSION - 160 countries (iOS/Android), 5 new languages, 3.5B users worldwide, 7-20M NA users
- 🪟 OpenAI ChatGPT Atlas: WINDOWS ROLLOUT (unverified) - Reported Windows 11 availability, 27.7% enterprise adoption maintained, no security patches, 1-3M NA users
- ⚖️ Perplexity Comet: AMAZON CONFLICT + REIMAGINED - Cease-and-desist from Amazon, new Assistant (23% better), Android beta invites, 4-7M NA users
- 🔄 Opera Neon: No major Week 45 updates, $19.99/month, ODRA deployed (W44), 100K-200K NA users
- 🔒 Dia Browser: No major updates, strong security reputation, $20/month Pro, 100K-250K NA users
Executive Summary
North American Market Size: 25-55M current users (25-22% week-over-week growth, decelerating but steady). OpenAI ChatGPT Atlas maintains 27.7% enterprise adoption and begins reported Windows rollout (1-3M NA users), Google Chrome AI Mode expands to 160 countries with iOS/Android support (7-20M NA users), Perplexity holds 6.6% AI search share (4-7M users) while launching reimagined Comet Assistant with 23% performance improvement and Android beta, Opera Neon maintains premium positioning (100K-200K users), Dia holds steady at $20/month Pro tier (100K-250K users).
Commerce Wars Begin: Amazon sent cease-and-desist letter to Perplexity on November 4, demanding Comet stop enabling purchases on Amazon.com and arguing agents must identify themselves and respect platform decisions. Perplexity countered with "Bullying is not innovation" blog post, claiming agents acting on user behalf have same permissions as users. Forbes called this the "battle for the future of commerce." This precedent-setting conflict introduces new risk layer for agentic browsers: potential exclusion from major e-commerce platforms. Conflict emerges as Amazon protects advertising revenue (Rufus shopping bot) from AI competition optimizing for user preference over sponsored placements.
Security Responses Remain Minimal: Despite Week 44's multi-source validation of prompt injection vulnerabilities, most players have not shipped security patches. OpenAI's November 5 Atlas update included only bug fixes and tab improvements—no security patches despite verified vulnerabilities from Fortune, The Register, and academic research. Fellou CE remains unpatched since August 2025 vulnerability disclosure. Only Perplexity has shipped dedicated security feature (Privacy Snapshot in Week 44). This lack of response stands in stark contrast to the 27.7% enterprise adoption rate, suggesting security concerns have not yet impacted growth trajectory.
Agentic Commerce Optimization (ACO) Emerges: The Amazon-Perplexity conflict has catalyzed a new discipline focused on optimizing for AI shopping agents rather than human searchers. AI agents prioritize structured data, specifications, pricing, and fulfillment over branding and marketing copy—rendering traditional SEO playbooks obsolete. Market showing continued maturation: legal frameworks emerging (Amazon precedent), platform gatekeeping battles beginning, six-week compound growth of 525-1000% since Week 40. Winners will be those who navigate both unresolved security challenges and emerging platform access conflicts while maintaining the productivity benefits driving rapid adoption.

Confidence Framework
Market Signals
Platform Wars Erupt as Security Responses Stall - Key Developments
Amazon sent cease-and-desist letter to Perplexity November 4, demanding Comet stop enabling purchases on Amazon.com. Amazon's position: agents must identify themselves and respect platform decisions whether or not to participate. Perplexity published "Bullying is not innovation" blog post, arguing agents acting on user behalf have same permissions as users. Forbes called this "the battle for the future of commerce." First major legal conflict introduces new risk layer: potential exclusion from major e-commerce platforms. Precedent-setting for entire agentic browser category.
Google expanded Chrome AI Mode to iOS and Android across 160 new countries November 5. Added support for Hindi, Indonesian, Japanese, Korean, and Portuguese. Estimated 3.5 billion Chrome users worldwide. Massive distribution play dwarfs competitors' reach. While current AI Mode lacks true agentic capabilities, feature roadmap announced signals future competition. Demonstrates big tech strategy: leverage existing ecosystem dominance while gradually adding AI agent features. Distribution power may prove more decisive than first-mover innovation.
Perplexity launched completely reimagined Comet Assistant November 6, claiming 23% performance improvement (internal tests). New capabilities: multi-tab operation (work across multiple tabs simultaneously), improved perception of complex websites, expanded action types, better persistence on complex tasks. Android beta invites began rolling out to active/paid users. Fighting on two fronts: Amazon legal conflict while shipping major product improvements. Demonstrates startup agility and feature velocity despite platform access challenges. 4-7M NA users maintained, 6.6% AI search market share stable.
Despite multi-source validation of prompt injection vulnerabilities in Week 44 (Brave, academic research, NBC News, OpenAI CISO), most players have not shipped security patches. OpenAI Atlas update (Nov 5, build 1.2025.302.4) included only bug fixes and tab improvements—no security patches. Fellou CE remains unpatched since August 2025 vulnerability disclosure. Only Perplexity has shipped dedicated security feature (Privacy Snapshot in Week 44). Response lag suggests either technical challenges in solving "frontier, unsolved security problem" or strategic deprioritization as 27.7% enterprise adoption persists without apparent slowdown.
Amazon-Perplexity conflict catalyzing new discipline focused on optimizing for AI shopping agents rather than human searchers. AI agents prioritize structured data, specifications, pricing, and fulfillment information over branding, marketing copy, and visual design. Traditional SEO playbook becoming obsolete—need machine-readable data, API integrations, semantic markup. Shelly Palmer (Syracuse professor, LinkedIn Top Voice) coined ACO framework. McKinsey estimate: agentic commerce could generate $1 trillion by 2030 (single source, treat with caution). Platform access conflicts will define which optimization strategies matter.
Market at 25-55M NA users with 25-22% week-over-week growth. Six-week trajectory shows compound growth of 525-1000% since Week 40, but rate steadily decelerating from 150% peak (Week 42) to current ~25%. Maturation indicators: legal frameworks emerging (Amazon precedent), platform gatekeeping battles beginning, growth rate stabilizing. Winners will navigate both unresolved security challenges AND emerging platform access conflicts while maintaining productivity benefits driving adoption. Central tension: platform wars now overlay unsolved security crisis.
