S&P Dow Jones Indices (S&P DJI) and Kalshi announced a preferred-provider collaboration on October 26 that gives the prediction-market operator a license to develop event contracts tied to S&P DJI indices.
The reciprocal part of the agreement makes S&P DJI a preferred provider to construct indices based on Kalshi event-contract data.
The announcement does not give a launch date or disclose financial terms.
Forthcoming Kalshi contracts under the agreement are intended to settle against official index levels published by S&P DJI. That would give the contracts a reference value calculated separately from Kalshi's order book.
S&P DJI's portfolio includes the S&P 500 and Dow Jones Industrial Average, giving the arrangement a potentially substantial benchmark footprint.
The release does not specify which indices will underpin the first contracts or how many contracts Kalshi expects to offer.
The companies also envisage using Kalshi market data to create new indices tracking expectations across economics, politics and sports. This is described as an opportunity that the partnership could enable.
No such new index, methodology, approval timetable or commercial target was announced. The two directions of the deal therefore have separate potential uses: established benchmarks for contract settlement and prediction-market data for possible new indices.
Kalshi Co-Founder and CEO Tarek Mansour said the arrangement supports its ambition to build a broader financial exchange. S&P DJI CEO Cathy Clay said it extends the index provider's reach into prediction markets.
For both firms, the agreement could connect regulated event contracts with financial benchmarks already used by institutional markets, although future adoption and product details remain open.
S&P DJI's legal notice draws a limit around the relationship. It says Kalshi contracts based on the S&P 500 or other S&P indices are not sponsored, sold or endorsed by S&P DJI. It also disclaims responsibility for trading decisions and certain index errors or interruptions.
The companies described each other's status as 'preferred', with no claim of exclusivity. Those distinctions matter as Kalshi develops the contracts and S&P DJI considers potential indices from its data.
Earlier in October, Kalshi introduced its US 500 index for perpetual futures. That was a separate, self-branded product; the new agreement concerns future contracts licensed to use S&P DJI benchmarks.
S&P DJI's release says its indices include the S&P 500 and Dow Jones Industrial Average, but it does not endorse Kalshi contracts based on those indices
