Index benchmarks are headed for a prediction-market makeover as Kalshi and S&P DJI team up 📈

Kalshi has struck a deal with S&P Dow Jones Indices that will let the prediction market platform offer event contracts tied to the index provider’s benchmarks. Kalshi will become a preferred platform for the products, which will settle against official index values published by S&P DJI, the companies said Monday.

Under the agreement, S&P DJI will also explore developing indexes that use Kalshi’s prediction market data to measure expectations about economic developments, political outcomes and sporting events. The proposed gauges would draw on prices from Kalshi event contracts rather than track the performance of traditional financial assets. Neither initiative has a disclosed timeline, and S&P DJI did not immediately respond to Cointelegraph’s request for additional details.

The agreement follows moves by traditional financial market operators into prediction markets. Intercontinental Exchange, parent of the New York Stock Exchange, committed up to $2 billion to Polymarket in October 2025. In March, Nasdaq filed to offer prediction market-style contracts tied to the Nasdaq 100 Index, before partnering with Kalshi in August to provide market surveillance technology.

S&P Global, the parent of S&P Dow Jones Indices, separately announced Monday that it completed its acquisition of blockchain security firm OpenZeppelin, expanding its risk assessment capabilities for digital assets. The deal was first announced in September, and financial terms were not disclosed. OpenZeppelin provides smart contract security audits and development tools, with its open-source contract libraries underpinning more than $38 trillion in value transferred and its security team conducting over 900 engagements.

OpenZeppelin will continue operating as its own business unit under founder Demian Brener, who will report to Yann Le Pallec, president of S&P Global Ratings. S&P Global has also expanded its digital asset risk assessment work beyond smart contract security. Earlier this month, S&P Global Ratings launched a framework for evaluating crypto lending vaults across six risk categories, including blockchain security, liquidity and governance.
