Block Acquires Afterpay ($29B)
Block's $29 billion acquisition of Afterpay in January 2022 remains the largest FinTech M&A deal in history, integrating Afterpay's 19 million consumers and 100,000+ merchants directly into Cash App and Square. By 2025, the combined BNPL and seller ecosystem processes over $200 billion in annualized gross payment volume — 50% more than legacy processor Fiserv — cementing Block as a full-spectrum financial services challenger.

S&P Global Merges IHS Markit ($44B)
S&P Global's $44 billion merger with IHS Markit in February 2022 created a financial data giant with over $12 billion in combined annual revenue, outperforming #5 Moody's by 40% in market reach. The deal unified S&P's credit ratings with IHS Markit's commodities data and fixed-income analytics, and by 2026, AI-enhanced data products serve over 90% of Fortune 500 financial decision-makers.

Intuit Acquires Credit Karma ($7.1B)
Intuit's $7.1 billion acquisition of Credit Karma in December 2020 brought 110 million members and a personal finance marketplace into TurboTax's orbit, creating a cradle-to-grave financial guidance platform. After DOJ scrutiny forced the sale of Credit Karma's tax filing business to Square, Intuit still serves 100 million+ consumers annually and generates over $2 billion in referral revenue — 60% faster growth than the average FinTech referral broker.

FIS Acquires Worldpay ($43B) — Then Reverses
FIS acquired Worldpay for $43 billion in 2019, the largest FinTech deal at that time, to create a payments-to-banking technology behemoth. However, by 2023 the merger collapsed — FIS sold a 55% stake in Worldpay to GTCR at a valuation of just $18.5 billion, erasing over $24 billion in value. This misstep cost FIS 50% more than Block's entire Afterpay deal, becoming a cautionary case study in integration risk between high-growth payments and legacy banking software.

Goldman Sachs Acquires GreenSky ($2.24B)
Goldman Sachs acquired GreenSky for $2.24 billion in 2022 to expand its Marcus digital banking platform, targeting home improvement BNPL for 4 million+ customers.

Stripe ($65B+ Valuation — No Acquisition Needed)
Stripe, the payments infrastructure giant co-founded by Patrick and John Collison, commands a $65 billion+ valuation from secondary market transactions as of 2024, making it the most valuable private FinTech company globally without an acquisition or IPO. It processes over $1 trillion in annualized payment volume for more than 1 million businesses. In 2025, Stripe entered stablecoin payments and AI-driven fraud detection, while its confidential IPO preparations target a valuation exceeding $100 billion.

Visa Blocked From Acquiring Plaid ($5.3B)
Visa's $5.3 billion acquisition of open banking pioneer Plaid was blocked by the DOJ in January 2021 on antitrust grounds, preserving Plaid as an independent force. Plaid now connects 8,000+ apps to 12,000+ banks via its API, processing over 20 million bank connections monthly, and raised $425 million at a $13.4 billion valuation in 2021. By 2025, Plaid dominates the US open banking infrastructure layer, processing 90% of all consumer-permitted data sharing requests. This outcome is slower than the average M&A velocity on this list but ensures Plaid remains a competitive throttle on Visa's debit network dominance.

Frequently Asked Questions About US FinTech M&A Deals

What does M&A mean? M&A stands for mergers and acquisitions. A merger is when two companies combine into one; an acquisition is when one company buys another. In financial technology, companies often do this to quickly gain new customers or technology instead of building them from scratch.

Which deal on this list was the largest? S&P Global's $44 billion merger with IHS Markit was the largest completed transaction on this list, closely followed by FIS acquiring Worldpay for $43 billion — though FIS later sold a majority stake in Worldpay, making it one of the most notable deal reversals in FinTech history.

Why do big banks and payment companies buy FinTech startups? Financial services process trillions of dollars each year, so even a small technology edge is worth billions. Acquiring a proven startup is often faster and cheaper than building the same capability in-house, especially in fast-moving areas like fraud detection, buy-now-pay-later, and open banking.

Can regulators block these deals? Yes. The US Department of Justice and other regulators can block acquisitions they believe will reduce competition. Visa's planned $5.3 billion purchase of Plaid is a prominent example on this list — regulators intervened to protect access to open banking data.
