S&P Dow Jones Indices and Kalshi have agreed to build indices that track real-world events and risks. Kalshi will settle its upcoming event contracts against official S&P DJI values. Neither company disclosed financial terms or a firm timeline.
The company behind the S&P 500 is moving into prediction markets. S&P Dow Jones Indices (S&P DJI) and Kalshi announced a partnership on October 26, 2026 to build indices that track real-world events and risks. Under the deal, Kalshi becomes the preferred prediction market platform for event contracts tied to S&P DJI benchmarks.
Kalshi gets official index values, S&P DJI gets market data
The arrangement runs in two directions. First, Kalshi will use official S&P DJI index values to settle its upcoming event contracts, including benchmarks such as the S&P 500.
Second, S&P DJI becomes the preferred index constructor using Kalshi data. It can build new indices that draw on the prices traders set in Kalshi's markets. Those indices could span economics, politics and sports.
Few details so far
Neither company disclosed financial terms, and no firm timeline for new products has been specified. There is a potential rollout for financial contracts by year-end 2026, but that is a possibility, not a promise.
Kalshi CEO Tarek Mansour emphasized that the collaboration would drive both retail and institutional interest in prediction markets. The collaboration may result in event-based benchmarks, but until products launch the concept remains on the whiteboard.
Kalshi is the largest US regulated prediction market
Kalshi was founded in 2018 and operates as the largest US regulated prediction market, supervised by the Commodity Futures Trading Commission. For S&P DJI, the appeal is data: prediction markets produce a continuous, real-time signal of what traders collectively expect.
Risks remain. A benchmark built on a thinly traded Kalshi market could reflect the views of a small group rather than a genuine consensus. It is also not yet clear who would use sports and political indices, or whether regulators would welcome them.
