SoFi Acquires UK Retail Investment Platform PrimaryBid in Cross-Border Fintech Deal
US financial services group SoFi has acquired PrimaryBid, a UK-based fintech that gives retail investors access to public market capital raises alongside institutional investors. The deal is structured as an asset purchase, with SoFi separately arranging for certain PrimaryBid team members to support the platform as it is integrated into SoFi's technology stack. PrimaryBid had built a distinctive niche in the UK market by democratising access to follow-on equity offerings and IPOs — transaction types that have historically been the preserve of institutional investors. Its technology connects retail brokers and individual investors to live capital market transactions at the same price as institutions. The acquisition gives SoFi a ready-built platform and UK regulatory footprint in public markets participation, complementing its existing retail brokerage and lending business in the US. For PrimaryBid, the deal represents a route to scale under a well-capitalised US parent rather than an independent fundraising path in a competitive fintech environment. The transaction is notable as a US-to-UK direction-of-travel acquisition in fintech — reversing the more common pattern of UK or European fintechs seeking US listings or partnerships. It reflects continued US strategic appetite for UK retail investment infrastructure, particularly as equity market activity recovers on both sides of the Atlantic.
Why this matters
The acquisition activates public M&A and tech M&A practice groups, with particular demand for asset purchase structuring, UK financial services regulatory advice (given PrimaryBid's UK broker authorisation), and employment work around the team retention arrangements. The deal also touches capital markets practice — PrimaryBid's core product is a capital-raising distribution mechanism, meaning any integration with SoFi's systems will require analysis of UK and EU market-facing regulatory permissions. The 'why now' driver is the broader recovery in equity issuance activity and US appetite for acquiring proven UK retail fintech infrastructure cheaply relative to building from scratch. No external advisers are named in the source.
On the Ground
On this type of cross-border asset acquisition, a trainee would assist with Companies House filings, verify conditions precedent (CPs) on the checklist, and index the completion bible. They would also support due diligence report indexing across the target's UK regulatory licences and material contracts.

Question you might get
“PrimaryBid holds UK regulatory authorisations that SoFi needs to continue operating the platform — what legal issues arise on a change of control of a regulated UK fintech, and how would you manage them in the deal timetable?”
Full answer
SoFi has acquired PrimaryBid, a UK fintech that plugs retail investors into live public market capital raises alongside institutions. The deal matters commercially because it gives SoFi immediate UK regulatory authorisation and a functioning product in a market it would otherwise take years to enter organically. It reflects a wider trend of US financial groups acquiring rather than building in the UK fintech space, particularly as equity issuance volumes recover. The retention structure — where PrimaryBid team members move to support the integrated platform — also flags the importance of people-related legal provisions in tech M&A. This suggests deal structures combining asset purchases with bespoke employment arrangements will remain common as acquirers prioritise talent continuity alongside IP.
