S&P Global Acquires OpenZeppelin to Expand On-Chain Risk Assessment
S&P Global is acquiring blockchain security firm OpenZeppelin to expand its risk assessment business for on-chain financial products, according to a news release dated September 17, 2026. The move follows S&P Global’s recent push into digital asset data and market infrastructure.
Acquisition to Support On-Chain Security Assessments
S&P Global said the transaction strengthens its risk assessment and ecosystem development capabilities in digital asset markets. The company plans to use OpenZeppelin to develop on-chain security assessments, benchmarks, and risk intelligence as capital markets shift onto blockchain.
S&P Global Ratings President Yann Le Pallec said the strategy focuses on “trusted data, benchmarks and transparent risk assessment” as digital assets and tokenized markets mature.
OpenZeppelin’s Smart Contract Security and Library
Founded in 2015, OpenZeppelin provides on-chain security assessments and secure development services. The firm’s open-source smart contract library is used widely across DeFi and traditional financial institutions.
S&P Global said OpenZeppelin contracts underpin more than $37 trillion in value transferred, including many of the largest stablecoins and tokenized funds.
Stablecoin and DeFi Credit Work Already in Place
S&P Global has already introduced stablecoin stability assessments. It has also produced a credit rating for a decentralized finance (DeFi) protocol, positioning the company to broaden coverage across on-chain assets and infrastructure.
Related Digital Asset Moves by S&P Global
The acquisition comes days after S&P Global led a strategic investment in digital asset data company Kaiko. The investment followed an agreement earlier in September 2026 to combine their cryptocurrency index businesses, according to a September 14, 2026 press release.
Regulatory Context in the US
In separate US policy developments, the Senate failed to pass the crypto-focused Clarity Act on September 15, 2026. First Digital Founder and CEO Vincent Chok said firms that planned around US clarity now need to pursue other options.
Why it matters
By combining OpenZeppelin’s smart contract security and assessment tools with S&P Global’s risk assessment capabilities, the deal aims to bring more standardized benchmarking and risk intelligence to on-chain finance as tokenized markets expand.
