Key US InsurTech investment stats in Q3 2026:
- US InsurTech funding dropped 49% QoQ in Q3
- California retained its position as the main US InsurTech hub with companies based in the state securing 37% of all deals
- AIUC, an artificial intelligence underwriting company building the audit, standards and insurance infrastructure for advanced AI systems, raised $40m in a Series A round, marking one of the biggest US InsurTech deals of the quarter
US InsurTech funding dropped 49% QoQ in Q3
US InsurTech market attracted 41 deals in Q3 2026, down 2% from 42 transactions in Q3 2025 and 2% from 42 in Q2 2026.
Funding came in at $577.1m, up 3% from $559.5m in Q3 2025 but down 49% from $1.1bn in Q2 2026.
Deal volume held broadly steady across both comparisons, while the sharp sequential decline in funding points to Q2 2026 being buoyed by a small number of larger transactions that did not carry through into the following quarter.
Average deal size stood at $14.1m in Q3 2026, compared with $13.3m in Q3 2025 and $27.2m in Q2 2026.
California retained its position as the main US InsurTech hub with companies based in the state securing 37% of all deals
California strengthened its position as the most active US InsurTech market in Q3 2026, with companies recording 15 deals and a 37% share of total activity.
This compares with 12 deals and a 29% share in Q3 2025, a 25% rise in volume that also pushed its proportional standing notably higher.
New York held second place in both periods but slipped in volume, falling from 12 deals and a 29% share in Q3 2025 to eight deals and a 20% share in Q3 2026, a 33% decline that also saw its share of overall activity narrow considerably.
Texas entered the top three with five deals and a 12% share, having not featured in the equivalent ranking a year earlier.
It displaced Florida, which had held third place in Q3 2025 with five deals and a 12% share but did not feature in the ranking in the more recent period.
The most consequential shift is the widening gap between California and New York, which were level in Q3 2025.
California has since pulled clearly ahead, pointing to a concentration of US InsurTech activity in the west coast market.
AIUC, an artificial intelligence underwriting company building the audit, standards and insurance infrastructure for advanced AI systems, raised $40m in a Series A round, marking one of the biggest US InsurTech deals of the quarter
The round was led by Ribbit Capital, with participation from First Harmonic and Terrain.
It follows an earlier $15m seed round backed by NFDG, bringing total funding to $55m.
The company is responding to mounting pressure across the AI industry for independent oversight, including public calls for frontier AI audits from senior figures at OpenAI, Anthropic and xAI.
Its flagship product, AIUC-1, is a certification standard built specifically for AI agents.
It stress-tests agents against threats including jailbreaks, hallucinations and data leaks, using 5,000 risk-and-attack combinations tailored to each business.
The standard was developed with more than 250 security and risk leaders.
Companies including Cursor, ElevenLabs, Harvey, KPMG, Lovable, UiPath and Fin have certified their products against it. AIUC draws a parallel with Underwriters Laboratories, where insurers funded safety certification for early electrical products.
Proceeds will extend its audits, standards and insurance offering from AI agents to frontier models.
