AI Market Intelligence Daily

1. The weekly AI market share ladders repriced sharply, with DeepSeek losing ground and Google gaining on the Kalshi boards. DeepSeek's "above 23.2%" contract fell 38% (91% to 56%) and its "above 23.9%" contract fell 60% (84% to 34%), while Google's "above 18.9%" contract rose 62% (13% to 21%). The combined shift implies this week's usage share settled roughly in the high teens to low twenties for both players, a meaningful rotation away from DeepSeek that no top-15 headline explains directly; the move appears driven by the weekly share data itself rather than news flow.

2. Claude became the most traded narrative of the day, jumping 186% (7% to 20%) in the "Best AI this week" market while Gemini's contract on the same board slipped 7% (86% to 80%). That swing lines up with the quiet strength in Anthropic's adjacent boards: the "above 4.0% market share" contract held at 91% and the IPO-announcement markets stayed firm, with 74% odds of an official announcement before January 1, 2027. Meanwhile OpenAI's own share ladder compressed hard, with its "above 18.8%" contract collapsing 89% (90% to 10%) and "above 19.2%" falling 88% (69% to 8%), suggesting OpenAI's week is tracking below the levels traders priced a day earlier.

3. The OpenAI IPO complex moved in one direction: lower and later. The "$1.5T or greater at market close on IPO day" contract dropped 19% (55% to 45%), the "$1.25T to $1.5T" contract rose 10% (10% to 12%), and the "closing market cap above $800B" contract eased from 88% to 81%, while the base "IPO by December 31, 2026" market stayed pinned at 4%. Net, the market is re-rating a 2026 listing toward the lower end of the valuation range and keeping 2027 as the more likely window. Anthropic, by contrast, is the preferred first mover: Kalshi prices a 92% chance that Anthropic announces its IPO before OpenAI does.

4. The day's biggest percentage mover, the "Will the U.S. ban any open-source AI model in 2026?" contract tripling from 1% to 3%, is a divergence worth flagging: with Meta's open-weight Mac model launching today, the news. cycle was decidedly pro-open-source, yet the ban odds ticked up. The move is small in absolute terms and likely reflects a handful of contracts traded on regulatory chatter, but it is the clearest example of price running against the day's headline sentiment. A second divergence sits in the benchmarks: "Will any AI model reach a Chatbot Arena score of at least 1600 by December 31?" rose 26% (7% to 9%) with no model-launch news in the top stories, implying traders are positioning for a late-2026 frontier release rather than reacting to anything published today.

5. Taken together, the boards say the frontier race is being re-sequenced: Gemini remains the default winner of "best AI this week" at 80%, but Claude is the momentum story,. Google is taking share at DeepSeek's expense, and the money is treating a sub-$1.5T OpenAI IPO as the baseline case for a 2027 listing. The only genuinely news-driven gap on the board is the open-source regulation market, where prices are edging against an open-weights-friendly news week.
