KKR & Co. sold a minority stake in its post-trade services provider OSTTRA to six global banks, marking one of the latest high-profile exits in the financial infrastructure sector. The deal, valued at $3.1 billion post-trade, reflects growing investor confidence in digital trading platforms as markets consolidate.

OSTTRA, which processes transactions for asset managers and institutional clients, will now collaborate with banks to enhance liquidity and connectivity in fragmented markets. Six banks—including major players in European and Asian markets—joined the consortium, though their identities remain undisclosed. This move underscores a strategic pivot by private equity firms to monetize stakes in specialized fintech ventures while banks expand their technological footprints.
