S&P Global and CME Group have completed the sale of their 50/50 joint venture, OSTTRA, to the global investment firm KKR in a deal valuing the post-trade processing company at $3.1 billion. The proceeds from the sale will be split evenly between S&P Global and CME Group. OSTTRA was formed in 2021 and provides post-trade processing, connectivity, and optimization services for various asset classes in the financial markets. The sale to KKR represents a strategic shift for OSTTRA, moving from joint ownership by market infrastructure firms to being backed by a major private equity investor.
