Google hits $4 trillion in market cap on partnership deal to power Apple AI features

Google's Stock Movement

Apple has recently announced a multi-year partnership with Google's Gemini to enhance AI features like Siri, leading to Google's market cap surpassing $4 trillion. Apple stated, "We determined that Google’s technology provides the most capable foundation for Apple’s foundation models and we’re excited about the innovative new experiences it will unlock for our users." Gemini has rapidly grown in market share, going from approximately 5% in early 2025 to over 18% by 2026, aided by its integration as the default assistant on over a billion Android devices including applications like Gmail, Docs, and Sheets. The Gemini 3 Pro consistently outperformed competitors in 19 out of 20 major benchmarks. Following the announcement, Google's stock price reached an all-time high but pared those gains soon after. The evolution of AI technology remains a significant theme for this decade, driving various investment themes forward, even as original trendsetters like Nvidia take a breather. Identifying the next hot story will be crucial going forward.
