  • SoFi Acquires PrimaryBid IPO Tool Amid Mixed Market Reactions
    May 13, 2026, 4:30 PM EDT. SoFi Technologies acquired PrimaryBid's IPO allocation technology to boost its presence in capital markets for retail investors. Despite this strategic move, shares fell 2.9% to $15.44 after Truist cut the price target from $20 to $17, citing concerns in both loan and technology segments. The acquisition ends PrimaryBid's run as an independent fintech and marks SoFi's deeper push into IPO access, where competitors like Robinhood also operate. SoFi posted strong Q1 results with a 43% revenue jump to $1.10 billion and increased members by 35%, yet a 16% fall in technology platform accounts and cautious Q2 revenue guidance suggest challenges ahead. Investors remain wary amid persistent rate pressures impacting consumer lenders.
