Market share dropped to 46.4% by May 2026 as Google's Gemini and Anthropic's Claude attract users with better retention and higher revenue per subscriber.

. This surpasses the previous record held by Google Maps, which took around five years to reach the same volume2

Google's Gemini and Anthropic's Claude Gain Ground
While ChatGPT still commands the largest user base with over 1.1 billion monthly active users, Google's Gemini has surged to 662 million users, capturing 27.7% market share, while Anthropic's Claude reached 245 million users with 10.3% of the market

. The AI market dynamics reveal dramatically different growth trajectories: Claude's monthly usage rose 640% year-on-year, and Meta AI jumped 973%, compared to ChatGPT's more modest 62% growth2

. Gemini's momentum stems largely from its integration with Google's broader ecosystem of tools, while Claude has built a strong reputation for productivity use cases and is closing in on ChatGPT's user retention rate1
. Other platforms including Grok, Perplexity, DeepSeek, and Meta AI collectively hold less than 5% market share1
.Pentagon Deal Triggers User Backlash and Uninstalls
A turning point came in February 2026 when OpenAI announced a deal with the U.S. Department of Defense to deploy its models on classified Pentagon networks. ChatGPT uninstalls surged approximately 295% day-on-day on February 28, the day after the announcement

. The Pentagon deal sparked immediate user backlash, with Claude soaring to the App Store's top spot that same weekend, outpacing ChatGPT by U.S. downloads for the first time2
. Anthropic gained momentum by refusing involvement in Pentagon operations and taking a public stance against autonomous weapons and mass surveillance3
. This episode demonstrates that brand trust and values alignment matter to users, not just features, according to Sensor Tower's analysis1

Claude Leads on Revenue Per User and Conversion Rates
While OpenAI maintains the largest user base, Anthropic's Claude is winning on monetization strategies. The Claude app generates approximately $2.76 per user compared to ChatGPT's $1.74, roughly 1.5 times as much revenue per user
5
. More significantly, 13% of Claude's users pay for a subscription plan, compared to 8% for ChatGPT, giving Anthropic the highest conversion rate in the field1
5
. This metric matters for investors evaluating which AI businesses are building lasting revenue streams. Claude's pricing strategy differs from competitors: it has no cheap tier and plans start at $20 per month, attracting heavier, paying users5
. ChatGPT and Gemini chase scale with low-cost options, which lifts user counts but dilutes average revenue. However, these figures represent consumer-app data from phone apps, not the enterprise contracts and API contracts where both companies generate most revenue5

. OpenAI also started experimenting with ads in ChatGPT in February, scaling gradually so that by May, an average of 17% of daily users were being served ads1
