OpenAI’s presence was noted at 39.7%, marking a slight increase of 0.23 percentage points. Meanwhile, xAI saw its utilization rise to 4.0%, up by 0.94 percentage points. Despite Anthropic’s broad adoption, its Fable 5 model accounted for only 6% of tokens purchased and 11.4% of total spend, contrasting with OpenAI’s GPT-5.6 Sol, which represented 25% of tokens and 23% of spend. The data from Ramp, which tracks AI product payments through its business card and invoice services, suggests that Anthropic maintains a lead in business adoption. Market participants are observing these developments closely, as they could influence Anthropic’s valuation prospects by the end of the year. ## Key Takeaways - Ramp’s data suggests Anthropic maintains a leading role in U.S. business AI adoption at 43.5%. - OpenAI’s usage among businesses slightly increased, capturing 39.7% of the market. - The limited uptake of Anthropic’s Fable 5 model may indicate a focus on broader strategic use rather than token volume. ## What to Watch Market participants will be monitoring Anthropic’s efforts to increase the adoption of its Fable 5 model, as this could impact its valuation trajectory. Any announcements regarding new funding rounds or expanded partnerships with strategic investors like Amazon or Google would be consistent with a YES outcome for increased valuation. Additionally, developments in regulatory scrutiny or competitive dynamics with OpenAI and xAI could influence market perceptions. *Get live prediction-market analysis, powered by Vera.
