How has funding activity in the AI governance market changed over time?
Q1 2026 was the most active quarter, with $242 million raised across five deals, mainly because Braintrust and WitnessAI raised $138 million combined.
Q3 2025 was the least active quarter because ALIGNMT AI announced the only qualifying deal, worth $6.5 million.
AI governance market funding fell by 8.0% from Q1 2026 to Q2 2026, but Q2 2026 funding was more than eleven times higher than in Q2 2025.

| Q2 2025 | 2 | $19M | Openlayer represented most of the quarter, while Trustible added a smaller enterprise governance round. |
| Q3 2025 | 1 | $7M | ALIGNMT AI was the only qualifying deal, making Q3 2025 the quietest quarter. |
| Q4 2025 | 7 | $90M | Deal volume increased as enterprises adopted governance tools for workforce AI, Copilot and regulated workflows. |
| Q1 2026 | 5 | $242M | Large rounds for Braintrust and WitnessAI helped make Q1 2026 the strongest quarter. |
| Q2 2026 | 6 | $223M | Funding remained high as investors supported agent security, testing, permissions and compliance controls. |
