AI Market Intelligence Daily

1. Anthropic's model market share is re-pricing sharply higher as its frontier models gain ground. The "Anthropic market share this week" strike above 3.1% on Kalshi jumped from 17% to 56%, and the strike above 3.45% followed the same direction, the single biggest AI-model move of the day. That re-rating lines up with Claude holding a 63% lead in the "Best AI on Dec 31, 2026" market and with this week's coverage of Anthropic's frontier work, including its public breakdown of distillation campaigns by Alibaba, Moonshot AI, and DeepSeek.

2. OpenAI's IPO calendar is trading on two very different time horizons. The chance of an OpenAI IPO by December 31, 2026 sits at just 8%, with a $1 trillion-plus IPO before 2027 at 6% and a $1.5 trillion valuation on IPO day at 3%, while Anthropic is the favored first to IPO at 89% and its 2027 IPO is priced at 86%. The gap between the near-term and 2027 probabilities is itself a signal: traders are treating 2026 as a lockout year for OpenAI but leaving a real tail for 2027, even as the OpenAI IPO-by-2027 contract inched up to 10%.

3. Compute prices for next week's H200 settlement are converging on a $4.50 to $5.00 band. The strike "above $4.50 at 4 PM ET on Sep 11" re-rated from 45% to 96%, while the "above $5.50" contract for the same timestamp collapsed to 2% and the "above $5.00" contract now sits at 72%. The shape of that curve says the market sees a soft, mid-$4s print rather than a spike, a modest read-through on near-term GPU rental demand.

4. OpenAI's research momentum is quietly repricing upward. The contract for "OpenAI announces another Millennium Prize solution before Jan 1, 2027" rose from 62% to 85% and its 2028 twin from 60% to 89%, and "Will any AI model reach a Chatbot Arena score of at least 1550 by Dec 31" jumped 88% to 22%. These benchmark markets moved on trading activity rather than today's headlines, but the direction is consistent with the OpenAI research news dominating the feed.

5. The day's top percentage mover has no AI catalyst behind it. The "Taiwanese Premier Cho Jung-tai out by December 31, 2026" market surged from 14% to 58%, a pure geopolitics move that only lands in the AI feed because of its Taiwan nexus. The reminder is that the top-mover list can be dominated by non-AI events, so the AI-specific signal this cycle lives in the share, IPO, compute, and benchmark markets rather than in the headline percentage gains.
