S&P Global agreed on September 17, 2026, to acquire smart-contract security company OpenZeppelin, extending its digital-asset risk business into the code used to issue, move and manage stablecoins, tokenized funds and decentralized-finance products. The transaction remains subject to closing conditions, while financial terms were not disclosed.
S&P Global said the acquisition will expand its risk-assessment capabilities into the onchain technology layer while giving OpenZeppelin access to S&P Global’s reach across traditional financial markets. The transaction adds smart-contract security to a digital-asset strategy that has already included stablecoin assessments, DeFi credit ratings, digital-asset indices and tokenized financial benchmarks.
“The transaction complements S&P Global's risk assessment and ecosystem development capabilities in digital asset markets, enhancing its ability to create the next generation of onchain security assessments, benchmarks, and deliver essential intelligence as capital markets transition onchain,” S&P Global said.
OpenZeppelin was founded in 2015 and provides onchain security assessments, secure-development services and open-source smart-contract libraries. Those libraries are used across much of the stablecoin and tokenized-fund market and have supported more than $37 trillion in cumulative value transferred. The figure measures transfers conducted through contracts using OpenZeppelin’s libraries rather than assets managed or held by the company.
OpenZeppelin has also conducted more than 900 security engagements for digital-asset protocols and institutions. S&P Global said those engagements surfaced more than 10,000 vulnerabilities before the affected code reached production, giving the company a security operation focused on identifying risks during development and review.
OpenZeppelin CEO Demian Brener said the company’s technology already underpins major segments of blockchain-based financial infrastructure.
“OpenZeppelin's standards, technology, and expertise already power the infrastructure behind the world's leading stablecoins, tokenized funds, DeFi protocols, and onchain markets,” Brener said. “With S&P Global, that foundation reaches a broader set of organizations entering this market, as well as the blockchain networks and DeFi protocols gaining institutional adoption.”
OpenZeppelin will remain a standalone business unit
OpenZeppelin will continue operating under its existing name as its own business unit after the transaction closes. Co-founder and CEO Demian Brener will remain in charge of the business and report to S&P Global Ratings President Yann Le Pallec.
Le Pallec said the acquisition fits S&P Global’s effort to bring its existing risk-assessment framework into tokenized and blockchain-based markets.
“Our digital assets strategy centers on bringing trusted data, benchmarks, and transparent risk assessment to markets as they move onchain,” Yann Le Pallec said. “As digital assets and tokenized markets continue to mature, OpenZeppelin's technology and expertise will complement our smart contract and onchain technology risk assessment capabilities, giving traditional financial institutions and DeFi-native companies alike the confidence to build and transact in this new environment.”
The combination extends S&P Global’s coverage beyond the financial characteristics of an issuer or protocol into the code underlying onchain products. Smart-contract flaws can create a separate technology risk even when reserves or a credit profile are sound, making code assessment another component of evaluating blockchain-based financial infrastructure.
S&P Global has been expanding its digital-asset coverage for more than a year. Its existing work includes stablecoin stability assessments as well as the first credit rating of a DeFi protocol, Sky. The OpenZeppelin transaction extends that work from assessing an entity’s financial characteristics to assessing technology used by onchain entities and products.
Deal follows broader digital-asset expansion
The OpenZeppelin agreement follows several other digital-asset initiatives by S&P Global, which was described as a roughly $120 billion company.
On Monday, September 14, 2026, S&P Global led a strategic investment that extended crypto market-data company Kaiko’s Series B funding round to $110 million. BNP Paribas, Nasdaq Ventures, Coinbase Ventures and Royal Bank of Canada also participated.
Earlier in September 2026, S&P Dow Jones Indices and Kaiko launched a co-branded digital-asset index suite. The companies had also tokenized the iBoxx U.S. Treasuries Index in March 2026.
Those initiatives place several parts of S&P Global’s digital-asset activity across market data, indices, tokenized benchmarks, credit and stability assessments, and smart-contract security. OpenZeppelin adds technology-risk capabilities around infrastructure already used by major stablecoins, tokenized funds, DeFi protocols and other onchain markets.
S&P Global said the acquisition is not expected to have a material impact on its financial results.
