OpenAI is showing Kalshi’s World Cup odds inside ChatGPT, its first prediction market deal

OpenAI has begun displaying prediction market odds from Kalshi inside ChatGPT search results, marking the first time the company has partnered with a regulated betting exchange. The integration, first reported by the New York Times, shows real-time odds for 2026 FIFA World Cup matches with a “Source: Kalshi” label but no outbound links or Kalshi branding. Users cannot place bets through ChatGPT, and OpenAI’s help page states the data is limited to queries related to the World Cup and is strictly for informational purposes.

The rollout coincided with the World Cup semifinals, with ChatGPT showing France at roughly 60 percent to beat Spain and England at roughly 55 percent to beat Argentina based on Kalshi’s prediction market contracts. Neither company has promoted the integration publicly, and the feature appears only when users ask ChatGPT about upcoming World Cup matches. OpenAI has not disclosed whether money changed hands or whether the arrangement involves revenue sharing.

The deal is the latest sign that prediction markets are embedding themselves into mainstream technology platforms at remarkable speed. Kalshi secured an exclusive partnership with CNN in late 2025 to integrate its odds into news broadcasts, with anchor Harry Enten using the data on air. In January, rival platform Polymarket struck its own exclusive deal with Dow Jones, bringing prediction market data to the Wall Street Journal, Barron’s, and MarketWatch.

Google has also brought both Kalshi and Polymarket data into its search results and Google Finance pages, making the two largest US prediction market platforms visible to hundreds of millions of users who may never have visited either site directly. Kalshi, which is regulated by the Commodity Futures Trading Commission, has positioned itself as the institutional-grade platform for prediction markets, raising roughly one billion dollars at a valuation of about $22 billion. Sports have become the most heavily traded category on both platforms this year, with the World Cup driving record trading volume.

For OpenAI, the partnership represents a new category of data integration for ChatGPT, which has already added advertising and shopping features to its search results this year. Showing real-time betting odds sits in a grey area between informational content and gambling promotion, and OpenAI’s decision to strip Kalshi’s branding and block direct betting suggests the company is aware of the sensitivity. The help page caveat that users “cannot place bets through ChatGPT” reads as much like a legal disclaimer as a product limitation.

Prediction markets remain controversial despite their rapid mainstream adoption. State regulators have challenged both Kalshi and Polymarket over certain contract types, and Google announced it will ban prediction market browser extensions starting in August. Whether surfacing betting odds inside an AI chatbot used by more than one billion people weekly normalises prediction markets or simply reflects how deeply they have already penetrated the information ecosystem is a question that neither OpenAI nor Kalshi appears eager to answer publicly.
