S&P Dow Jones Indices Partners with Kalshi to Bring Index-Linked Event Contracts to Prediction Markets

S&P DJI Becomes Settlement Backbone for Kalshi's Index Contracts

S&P Dow Jones Indices and prediction-market exchange Kalshi have formalised a partnership that will let the platform offer event contracts tied directly to S&P DJI benchmarks. Under the arrangement announced on Monday, Kalshi will operate as a preferred venue for contracts whose settlement is anchored to the official index values published by the index provider.

Beyond simply licensing existing indexes, the two firms plan to explore building entirely new gauges derived from Kalshi's own prediction-market data. These proposed measures would not track the performance of stocks, bonds, or other conventional assets. Instead, they would use the prices embedded in Kalshi's event contracts to capture market expectations surrounding economic releases, political outcomes, and even sporting results. Neither company has indicated a target date for launching either component, and S&P DJI did not immediately respond to follow-up inquiries seeking additional detail.

A Growing Wave of Wall Street Firms Entering Prediction Markets

The Kalshi–S&P DJI deal is the latest chapter in a broader pattern of incumbent financial-market operators extending their reach into the prediction-market space. Intercontinental Exchange, the parent company of the New York Stock Exchange, committed as much as $2 billion to Polymarket last October. Nasdaq, meanwhile, filed in March to list prediction-market-style contracts linked to the Nasdaq 100 Index and subsequently partnered with Kalshi in August to supply market-surveillance technology for those offerings.

For brokers and their clients, the significance lies in the convergence of two previously separate trading universes. Event contracts that once existed almost exclusively on specialised crypto-adjacent platforms are now being wired into the same index infrastructure that underpins futures, ETFs, and structured products. Traders who follow macro data, earnings calendars, or geopolitical events may soon access exposure to those outcomes through venues that settle against the same official index prints they already rely on.

S&P Global Completes OpenZeppelin Acquisition, Broadens Crypto Risk Mandate

On the same day, S&P Global – the parent of S&P Dow Jones Indices – confirmed the completion of its acquisition of blockchain-security firm OpenZeppelin. The purchase was first revealed in September, and financial terms were not made public. OpenZeppelin is best known for its open-source smart-contract libraries, which, according to S&P Global, underpin more than $38 trillion in cumulative value transferred, and for a security team that has carried out over 900 audit engagements.

Post-acquisition, OpenZeppelin will continue to operate as a standalone business unit. Founder Demian Brener will remain at the helm and report to Yann Le Pallec, president of S&P Global Ratings.

The acquisition fits into a wider push by S&P Global Ratings into digital-asset risk assessment. Earlier this month, the ratings arm rolled out a framework for evaluating crypto lending vaults across six risk categories, including blockchain security, liquidity, and governance. For institutional traders and their compliance teams, the signal is clear: the same ratings houses that score sovereign debt and corporate credit are now building the analytical scaffolding for on-chain and prediction-market exposures.
