From Kaiko to OpenZeppelin, S&P Global is quietly preparing for markets that never close

According to CryptoSlate, S&P Global agreed to acquire smart contract security firm OpenZeppelin to expand its digital asset business into the technology underpinning tokenized finance. OpenZeppelin will operate as a separate business unit under its own name, led by Chief Executive Demian Brener, who will report to S&P Global Ratings President Yann Le Pallec. Financial terms were not disclosed, and the transaction remains subject to closing conditions.

The deal gives S&P direct exposure to the security layer behind stablecoins, tokenized funds, and decentralized finance applications. OpenZeppelin’s open-source contracts have supported over $37 trillion in transferred value. This acquisition follows S&P leading a strategic investment in crypto-data provider Kaiko, extending Kaiko's Series B funding to $110 million. These moves broaden S&P's position across market data, benchmarks, and technology risk as financial markets push toward 24/7 trading. S&P stated that OpenZeppelin's libraries will remain free, open source, and publicly maintained. Le Pallec noted that the digital assets strategy centers on bringing trusted data, benchmarks, and transparent risk assessment to markets as they move on-chain.
