Methodology Components (Federal Market Adjusted):

Traffic Data (50%): Web dominance (35%) + Mobile performance (15%) with 70/30 weighting to capture mobile-web divergence. Microsoft 1.4x bias correction maintained. Growth & Momentum (20%): Usage records + viral sustainability with maximum 8pp change limits. Enterprise & Federal (20%): Federal deployment strength (12%) + enterprise positioning (8%). Strategic Positioning (10%): Market position + innovation factors assessment.

Enterprise Integration Success: Microsoft Copilot's +6.5pp surge validates enterprise-focused strategy effectiveness. Framework captures Office 365 integration advantages and federal adoption acceleration through enhanced enterprise component weighting.

Mobile-Web Divergence Captured: Gemini's -8.0pp decline despite #1 App Store ranking demonstrates framework's ability to distinguish viral mobile features from sustained web traffic dominance. 70/30 web/mobile weighting prevents temporary trends from distorting long-term market analysis.

Funding-Market Disconnect Recognition: Claude's -2.8pp decline despite $13B funding round demonstrates framework's independence from funding announcements. Market share calculations based on user adoption rather than investment metrics for accurate competitive assessment.

Federal Market Emergence Validated: OpenAI's $200M Pentagon contract, xAI's federal agreement, and accelerating government adoption reshape competitive dynamics. Enhanced enterprise component captures government validation as major strategic differentiator.
