Launch Catch-Up — Transaction Completed October 26, 2026

S&P Global completed its acquisition of blockchain-security company OpenZeppelin on October 26, expanding its technology-risk assessment capabilities for digital assets.

The companies first announced the transaction September 17. The new development is the closing, rather than a new agreement to negotiate or a proposed acquisition awaiting completion.

Financial terms were not disclosed. S&P Global said it does not expect the transaction to materially affect its financial results.

OpenZeppelin will retain its name and operate as a separate business unit. Founder Demian Brener will continue leading it and report to S&P Global Ratings President Yann Le Pallec.

Founded in 2015, OpenZeppelin provides security assessments, development services and open-source smart-contract software. Brener said its Contracts library would remain free, open source and publicly maintained.

Smart contracts execute programmed rules on blockchains. The acquisition announcement concerns ownership and capabilities; it does not establish that any particular digital asset or contract is free of coding vulnerabilities or financial risk.
