Top Prediction Movements
1. OpenAI's weekly market share ladders repriced sharply, with the "above 21.7%" strike jumping from 1% to 15% while the "above 19.3%" strike collapsed from 9% to 2%. The two strikes bracket a consensus landing zone near 19%, so the move reads as traders pulling in both tails of the distribution rather than betting on one direction. Nothing in the day's news flow explains a step change in OpenAI's app share, which makes this the clearest example of trading-activity-driven repricing in today's report.
2. Anthropic's share ladder went the other way, with the "above 2.8%" strike crashing from 15% to 1% and the "above 2.7%" strike from 81% to 6%. Together with the Qwen ladder collapsing from the 17-20% range to 1%, the week's share market is consolidating around OpenAI and DeepSeek, with DeepSeek's "above 24.1%" strike firming from 60% to 99%. The story the ladders tell is a concentration of app usage into two winners, and it arrives the same week Anthropic announced an $11.6 billion, seven-year cloud deal with Akamai — a spend commitment that is bullish for Anthropic's roadmap but apparently not yet for its consumer usage numbers.
3. The big picture on OpenAI's capital markets barely budged, with a year-end 2026 IPO still priced near a coin flip at 5% and "OpenAI not IPO by December 31" holding at 96%. What moved more is the shape of that market: the IPO-day market cap ladders remain stacked high, with above-$1T at 63% and above-$1.6T at 60%, while the below-$500B strike sits at 1%. The market is effectively pricing an OpenAI that may never list in 2026 but, if it does, debuts at a valuation above a trillion dollars — a stance consistent with the $1T-plus valuation market sitting at 75%.
4. Anthropic's IPO trajectory is the other side of that same trade, with "Anthropic IPO before 2027" at 76% and "OpenAI or Anthropic IPO first" at 91% for Anthropic. One divergence is worth flagging: "Will Anthropic have the highest IPO market cap of 2026?" slipped from 48% to 45%, even as Anthropic's near-term IPO odds look firm. Read with the OpenAI ladders above, the market is pricing Anthropic as the likely first to list but still behind OpenAI on ultimate size — a subtle bearish tilt on Anthropic's relative valuation that the day's positive news (the Akamai deal, the Trump dinner, the SNL profile) does not obviously warrant.
5. Momentum markets are quietly rotating toward the model release cycle as traders price in a late September Gemini 4 launch. "What will be the top AI model on Sep 28" rose from 4% to 9% on the leading strike, "top model this month" doubled from 2% to 5%, and the best-coding-model-on-December-31 market for the front-runner rose from 2% to 5%, while Claude's "best AI on Dec 31" odds sit at 74% and Gemini's at 8%. On the release side, the Gemini 4 market before October 16 is at 43% against 1% for October 1 — a tight two-week window that suggests traders are clustering a late-September to early-October Gemini release, even though none of the day's headlines confirm it.
