OpenAI adds Kalshi World Cup prediction odds to ChatGPT search

OpenAI has begun showing Kalshi’s World Cup prediction market odds in ChatGPT search results, extending market-based sports forecasts into the AI assistant’s search experience. The integration, first reported by The New York Times, was not publicly announced at the time of publication, and ChatGPT does not let users place bets; OpenAI’s guidance says the Kalshi data is for informational purposes only. When users search World Cup matchups, ChatGPT displays charts with each team’s implied chance of winning based on Kalshi markets. The reported examples showed France with a 59% chance against Spain and England with a 55% chance against Argentina. The move is described as OpenAI’s first known partnership with a prediction market platform, underscoring broader interest from technology and media companies in using prediction markets, where users trade contracts linked to event outcomes, as a source of real-time forecasts. Kalshi, a regulated prediction market platform, recorded more than $33 billion in monthly notional volume in June 2026, about $22 billion ahead of Polymarket, according to Dune Analytics data cited in the earlier report. The company had already partnered with CNN and CNBC in December 2025, while rival Polymarket struck a deal with Dow Jones in January 2026. Google also added prediction market data from Kalshi and Polymarket to Google Finance and Search in November 2025.
