Not: Q3’25 AI deal count

Deals were down 22% QoQ, but funding remained above $45B for the fourth consecutive quarter.

You can do the math: AI rounds are getting even bigger.

The average deal size in 2025 YTD is $49.3M — up 86% from 2024.

Investors are funneling capital into fewer, larger bets, driven by the massive infrastructure costs.

In Q3’25, the top 3 $1B+ rounds went to LLM developers, reflecting the high cost of frontier model development:

• Anthropic ($13B, Series F)
• OpenAI ($8.3B, PE)
• Mistral AI ($1.5B, Series C)

See the full breakdown of AI funding trends in our State of AI Q3’25 report.

Hot: AI agent exits

Q3’25 marks the second highest quarter on record for AI startup M&A (172 deals).

Three of the top 5 exits in the quarter were related to AI agents:

• Workday acquired Sana Labs, a company focused on enterprise workflows, for $1.1B
• NiCE acquired customer support startup Cognigy for $955M
• Atlassian acquired The Browser Company, the maker of the Arc and Dia AI browsers, for $610M

Not: Space cyberattacks

SpaceX is set to build a $2B satellite constellation for Trump’s Golden Dome missile defense system.

As space infrastructure is evolving into critical commercial applications, space cybersecurity is now a necessary defense.

Using our proprietary Mosaic score — a predictive measure of private company health and success — we identified the leading companies driving momentum in the space cybersecurity market.
