Key US FinTech investment stats in Q3 2025:
- US FinTech deal activity increased by 20% YoY
- Californian companies secured a third of all deals to dominate the US FinTech marketplace in Q3
- SEON, a Texas-based fraud prevention and anti-money laundering (AML) technology company, secured one of the biggest US FinTech deals in Q3 with an $80m Series C funding round
US FinTech deal activity increased by 20% YoY
In Q3 2025, the US FinTech industry experienced solid growth in both funding and deal activity, reflecting renewed investor confidence in the sector.
Total funding reached $11.4bn across 583 deals, marking a 34% increase in funding and a 20% rise in deal activity compared to the $8.5bn and 487 deals recorded in Q3 2024.
However, when compared to the previous quarter(Q2 2025), funding declined by 24% from $14.9bn, even as deal activity grew by 7%, indicating that while more transactions were completed, average deal sizes were smaller.
Overall, the results suggest that investor appetite for FinTech innovation remains strong, with capital continuing to flow toward a broader set of companies despite some moderation from the exceptionally high levels of the prior quarter.
Californian companies secured a third of all deals to dominate the US FinTech marketplace in Q3
California maintained its position as the leading FinTech hub in the US with companies in the state securing 186 deals (32% share) in Q3 2025, representing a 32% increase from the 141 deals (29% share) recorded in Q3 2024.
New York followed with 126 deals (22% share), up 18% from 107 deals (22% share) in the same period last year.
Florida ranked third with 37 deals (6% share), a 19% increase from 31 deals (6% share) in Q3 2024.
Despite fluctuations in overall funding levels, these three states continued to dominate the US FinTech landscape, collectively accounting for more than half of all deal activity.
The continued rise in deal volume across these leading states highlights the sustained strength and geographic concentration of the US FinTech ecosystem.
