US fintech M&A accelerated through August and September, after four consecutive quarters in which global deal value had fallen. Visa, Mastercard, Vanguard and Chime each announced or completed acquisitions in a five-week stretch, reversing a slowdown that had pulled quarterly deal value from a 2025 high of $76.6 billion down to $24.3 billion by the second quarter of 2026.
Four quarters of cooling before the rebound
Hyde Park Capital’s research note on the first quarter of 2026 put global fintech M&A at 347 deals worth $32.4 billion, a six-quarter low in deal count, while fintech IPO activity normalised to 11 offerings, down from a 12-quarter high of 25 in the previous quarter. Deal value had already fallen from $46.1 billion in the fourth quarter of 2025 and a 2025 peak of $76.6 billion in the third quarter. FT Partners then recorded a further slide in the second quarter, to $24.3 billion, with no single transaction reaching $15 billion; Bullish’s $4.2 billion purchase of share registrar Equiniti was the period’s biggest deal. The same report found private financing deal count down 14 percent on the first quarter and 29 percent year on year, even as six new fintech unicorns were minted and existing leaders such as Ramp and Airwallex reached higher valuations.
PitchBook’s Q2 2026 global M&A report pointed to one reason corporate buyers had more room to move: a friendlier antitrust posture in Washington and a more permissive tone from regulators in Brussels and London, even as private equity buyout activity fell because rising rates from the Federal Reserve made those deals harder to finance. That climate favours strategic acquirers such as networks, card schemes and large banks, which are behind most of the deals fintech has seen since August.
The data behind those figures tracks the global fintech market rather than the US alone, since no comparably granular US-only fintech M&A count is published quarterly. What has changed since is where the deals are coming from: every acquirer in the run described below is US-headquartered, even where the company they are buying is not.
Where the fintech M&A money went in August and September
The pace changed quickly. On 3 August, Visa agreed to buy fraud-detection specialist BioCatch for $2.4 billion in cash, adding behavioural and device signals used by more than 350 banks to its existing fraud and risk tools. The same day, Mastercard completed its purchase of stablecoin infrastructure provider BVNK, a deal worth up to $1.8 billion that the two companies had first agreed in March. On 26 August, Vanguard said it would acquire Altruist, a custody and portfolio platform for independent financial advisers it had backed as a minority investor since 2020; neither company disclosed terms, though the Wall Street Journal reported people familiar with the matter valuing the deal at roughly $4 billion. Then, on 8 September, Chime agreed to buy Stride Bank, its sponsor bank of more than seven years, for $590 million in cash, a deal it expects to close in the first half of 2027 once the Office of the Comptroller of the Currency and the Federal Reserve sign off.
The three deals with company-disclosed prices, Visa’s, Mastercard’s and Chime’s, total close to $4.8 billion on their own, in barely five weeks. Chime said owning Stride outright, rather than renting its charter, should save the company more than $100 million a year, mainly through lower funding costs and by eliminating the fees it currently pays its own sponsor bank; the transaction values Stride at about 1.5 times its tangible book value.
Private equity moved on the same theme, in the same window. On 10 August, Francisco Partners agreed to buy Moneris Solutions, Canada’s largest merchant acquirer, from its bank owners BMO and RBC for roughly C$2 billion (about $1.44 billion), with both banks staying on as long-term referral partners rather than exiting the relationship entirely. It is the same pattern as the strategic deals above: a regulated, revenue-generating payments business changing hands, not a new one being built from scratch.
733Park, a boutique advisory that tracks payments, fintech and vertical-software acquisitions, counted 24 announced deals between the start of August and mid-September, six of them in what it labels fintech infrastructure, the single busiest category on its list, and most of the rest split across fraud, cross-border payments and vertical software.
Infrastructure over disruption
None of these deals is a bet on a new product category. Visa bought a fraud signal it lacked. Mastercard bought a working stablecoin rail rather than build one from scratch. Vanguard bought the custody and adviser technology it had already backed for six years. Chime bought the bank charter it had rented from Stride for seven years, and Francisco Partners bought a merchant acquirer its own bank owners no longer wanted to run. Fintechly’s coverage of insurtech funding buying infrastructure rather than disruption found the same shift in August, and the pattern now extends across fintech more broadly: owning a regulated capability outright is winning out over renting it indefinitely.
That is a narrower kind of dealmaking than the one that produced 2025’s record quarters, when a handful of very large transactions carried the headline totals. The current run has no single deal above $2.4 billion, yet it has moved faster and involved a wider spread of buyers than the first half of 2026 did. Whether that pace holds through the fourth quarter will show up in the next round of deal-volume reporting, not in any one announcement.
The moves sit within a wider consolidation of US fintech that Fintechly continues to track sector by sector. A fuller list of the investors and acquirers active in the space is on Fintechly’s capital sector directory.
