London-based Calastone, a global leader in blockchain-powered fund infrastructure, has announced its acquisition by SS&C Technologies Holdings in a transaction valued at approximately £766m.
Founded in 2007, Calastone operates the world’s largest blockchain-enabled transaction network for investment funds. Its infrastructure connects more than 4,500 financial organisations across 57 markets, automating trading, settlement and distribution of fund transactions through a distributed ledger model.
The acquisition will see Calastone join SS&C’s Global Investor & Distribution Solutions division. Together, the companies aim to build a unified, real-time operating platform to reduce complexity and risk in fund operations—while accelerating digital innovation across the asset and wealth management landscape.
“This is a proud moment for everyone at Calastone,” said Julien Hammerson, chief executive. “SS&C’s global scale and deep expertise across fund services and technology will enable us to accelerate innovation and deliver new digital capabilities to the market.”
SS&C chairman and CEO Bill Stone hailed the move as a step toward a smarter fund ecosystem.
“Calastone has built an impressive network and platform, and together we will create a more connected, automated and intelligent global fund ecosystem,” he said.
The deal follows Calastone’s transformative partnership with The Carlyle Group, which acquired a majority stake in 2020. Since then, Calastone has expanded into ETF servicing and digital investments via tokenisation—positioning itself at the forefront of distributed ledger technology adoption in institutional finance.
“We are confident that SS&C is the right partner to continue Calastone’s success,” added Fernando Chueca of Carlyle Europe Technology Partners. “Its well-established technology network represents a differentiated, automated offering, and we look forward to watching the company thrive in its next phase.”
The transaction signals continued momentum behind blockchain-based infrastructure in financial markets, as fund managers seek scalability, reduced operational risk, and greater transparency in investment operations.
Subject to regulatory approvals, the deal is expected to complete in Q4 2025.
