S&P Global Acquires OpenZeppelin to Rate Smart Contract Risk
S&P Global announced on September 17, 2026 that it has acquired OpenZeppelin, the industry standard for smart contract security, in a move that extends the ratings firm's risk-assessment mandate into the technology-risk layer of digital assets. OpenZeppelin's libraries underpin over $37 trillion in cumulative transfers and power 8 of the top 10 stablecoins, including USDC, and 10 of the top 10 tokenized money market funds, such as BlackRock's BUIDL and Franklin Templeton's BENJI. OpenZeppelin will operate as a separate business unit led by CEO Demian Brener, who will report directly to Yann Le Pallec, President of S&P Global Ratings. The deal lands on the same day the SEC granted a 5-year exemption for tokenized NMS stock trading, aligning with the broader GENIUS Act framework, and ahead of the DTCC Tokenization Service launch in October 2026. S&P Global is positioning itself as the gatekeeper of the technical standards regulators are expected to require for tokenized markets.
