S&P Dow Jones Indices has partnered with prediction market platform Kalshi to enable the exchange to offer event contracts tied to the index provider’s benchmarks. Under the agreement announced Monday, Kalshi will become a preferred platform for these contracts, with settlement based on official index values published by S&P DJI. 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 rather than traditional asset performance. Neither party disclosed a timeline for these initiatives.
This collaboration follows broader moves by traditional financial institutions into prediction markets. Intercontinental Exchange committed up to $2 billion to Polymarket in October 2025, while Nasdaq filed to offer prediction market-style contracts in March before partnering with Kalshi in August for market surveillance technology. Separately, S&P Global completed its acquisition of blockchain security firm OpenZeppelin on Monday, expanding its digital asset risk assessment capabilities. Financial terms were not disclosed. OpenZeppelin, which provides smart contract audits and development tools underpinning more than $38 trillion in value transferred, will continue operating as its own business unit under founder Demian Brener.
The partnership between S&P Dow Jones Indices and Kalshi signals a strategic convergence between established benchmark providers and emerging prediction market infrastructure. By leveraging official index values for settlement, S&P DJI lends credibility and standardization to Kalshi’s financial event contracts, potentially accelerating institutional adoption of this asset class. This move reflects a broader trend where traditional finance entities are integrating prediction markets not just as trading venues, but as data sources for measuring collective market expectations on non-traditional variables like political or economic outcomes.
Simultaneously, S&P Global’s completion of the OpenZeppelin acquisition highlights an expanding focus on digital asset security within mainstream financial services. As prediction markets increasingly intersect with crypto-based instruments, robust risk assessment frameworks become critical. The integration of OpenZeppelin’s audit capabilities into S&P Global Ratings suggests a proactive approach to managing operational risks associated with smart contracts and decentralized finance protocols, positioning the firm to address compliance and security concerns that may hinder wider institutional participation in these novel financial products.
