Top 10 Fintech Startups in the US in 2026

These ten companies, which have secured a combined US$12.7 billion, are among the most prominent, valuable, and well-funded fintech startups in the US.
Forbes has released its annual Fintech 50 2026 list, highlighting the most promising private companies reinventing finance through technology in the US.

This year’s selected firms have continued to innovate and grow rapidly despite a tough market, subdued valuations, and a constrained funding environment. They have demonstrated strong revenue growth, impactful product innovation, and high‑quality leadership.

In 2026 again, business-to-business (B2B) banking dominates the Fintech 50 list with eleven entries. Almost every B2B banking firm that appeared in the previous edition returned for 2026, indicating sustained growth and continued innovation. Notable examples include Mercury, a neobanking platform serving more than 200,000 companies and entrepreneurs; and Ramp, a corporate credit card startup with annualized revenue of US$1 billion.

Following B2B banking, software providers serving Wall Street firms and large enterprises are the second largest category in the Fintech 50 list with nine companies. These include Antithesis, a Virginia-based autonomous software‑testing company serving trading firms like Jane Street; and Maybern, a New York-based fund management infrastructure for private equity, private credit, and real estate firms.

Collectively, the 2026 Fintech 50 have secured US$19.6 billion in funding, according to Forbes, with individual totals ranging from US$2.3 billion for Ramp and Polymarket, to companies that have yet to raise external capital, such as Increase and Hyperliquid. This illustrates a wide spectrum of growth stages.
