What will OpenAI's share be on Oct 28, 2026?

Comparing prediction market odds to analyst forecasts reveals how collective intelligence differs from expert opinion. Currently, the prevailing sentiment in this market, as reflected by the odds on Kalshi, may align with or diverge from projections made by industry analysts regarding Vercel’s future spending. If analysts predict a significantly higher or lower share for OpenAI than what is priced into this market, it could present an opportunity for informed traders. It’s important to remember that prediction markets represent a broader range of perspectives than a single analyst’s report.

On Kalshi, this market is priced through a continuous double auction, where traders buy and sell contracts representing their beliefs about the outcome. The price of a contract reflects the probability of that outcome occurring, as determined by supply and demand. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders can take either the 'buy' side, expressing a belief that the actual share of spend will be higher than the current market price, or the 'sell' side, believing it will be lower. This dynamic pricing mechanism allows the market to aggregate information and reflect the collective wisdom of participants.

This market resolves around Oct 29, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will be based on publicly available data regarding Vercel’s reported spend with OpenAI as of October 28, 2026. The market will determine the percentage of Vercel’s total spend allocated to OpenAI at that specific point in time. The outcome will be determined by a verifiable source of information, ensuring a transparent and objective resolution process for this market.

Several signals or events could significantly move this market before Oct 29, 2026. Major announcements from either OpenAI or Vercel regarding their partnership, new product launches, or changes in strategic direction would be key catalysts. Broader economic trends impacting cloud spending, or shifts in the competitive landscape of AI services, could also influence trader sentiment. Unexpected news regarding the performance or capabilities of OpenAI’s models, or any disruptions to Vercel’s infrastructure, could all lead to price fluctuations in this market.
