ChatGPT Analysis
Strengthens dominance to 68.1% (+2.9pp) following GPT-5 launch on August 7th, demonstrating technology ownership advantage. Scale reaches 700M weekly users with 5M business users, proving consumer-to-enterprise adoption model. Technology leadership translates directly to market share gains while competitors decline despite accessing same GPT-5 models through partnerships.
Microsoft Copilot Analysis
Experiences concerning 7.9pp decline to 14.2% despite gaining GPT-5 access through OpenAI partnership, revealing user experience gaps. Maintains strong enterprise positioning with 60% business focus and 2.5M business users, but implementation quality lags behind native ChatGPT experience. Integration advantages insufficient to overcome UX deficiencies.
Google Gemini Analysis
Declines to 7.6% (-4.7pp) despite massive ecosystem reach across Search, Android, and Workspace platforms. Integration strategy faces measurement complexity due to fragmented usage across Google services. Low confidence score (3.0/10) reflects difficulty tracking usage distributed throughout Google's ecosystem rather than concentrated standalone platform adoption.
Perplexity Analysis
Maintains stable 6.5% market share with highest measurement confidence (8.9/10), demonstrating successful search-augmented AI specialization. Consistent positioning proves viability of niche differentiation strategies in concentrated market. Platform's stability amid major competitor volatility indicates strong product-market fit within specialized segment.
