S&P Dow Jones Indices has partnered with prediction market platform Kalshi in a deal that will allow the exchange to offer event contracts linked to S&P DJI's benchmarks. Settlement of these contracts will be based on official index values published by S&P DJI.
Under the agreement, Kalshi becomes a preferred platform for contracts tied to S&P DJI indices. The companies also plan to explore developing new indexes using Kalshi's prediction market data, which would track expectations around economic developments, political outcomes and sporting events by measuring prices from Kalshi's event contracts rather than traditional financial asset performance.
The partnership reflects broader movement by established financial market operators into prediction markets. Intercontinental Exchange, parent company of the New York Stock Exchange, committed up to $2 billion to Polymarket in October 2025. Nasdaq filed to offer prediction market-style contracts tied to the Nasdaq 100 Index in March and later partnered with Kalshi in August to provide market surveillance technology.
In a separate development, S&P Global completed its acquisition of blockchain security firm OpenZeppelin on Monday. The deal, first announced in September, expands S&P Global's risk assessment capabilities for digital assets. OpenZeppelin provides smart contract security audits and development tools, with its open-source contract libraries supporting more than $38 trillion in value transferred and its security team having conducted over 900 engagements.
OpenZeppelin will operate as its own business unit under founder Demian Brener, reporting to Yann Le Pallec, president of S&P Global Ratings. S&P Global Ratings also launched a framework earlier this month for evaluating crypto lending vaults across six risk categories, including blockchain security, liquidity and governance.
