# Mistral raises €3B at €21B valuation, Europe's largest-ever tech equity round

Mistral AI raised €3 billion (~$3.5B) in a Series D at a post-money valuation of over €21 billion on 2026-09-08, led by Samsung Electronics with EQT's Scaleup Europe Fund and PSG as co-leads; it plans to build 1 GW of European compute by 2030 as it pivots toward sovereign AI infrastructure.

## Key facts
- €3B raised; post-money >€21B (~$24.4B), nearly double the €11.7B valuation a year earlier
- Lead: Samsung Electronics; co-leads EQT-managed Scaleup Europe Fund and PSG Equity
- Also: a16z, Nvidia, Salesforce Ventures, Advent, BlackRock, Grand Duchy of Luxembourg; ASML is a major partner/investor
- Mistral calls it the largest equity round ever by a European tech company
- Target: 1 GW of compute capacity in Europe by 2030; operates in 20 countries
- July 2026: multibillion-dollar expanded Microsoft partnership (Mistral Medium 3.5, OCR 4 on Foundry)

## What happened

President Macron framed the Franco-Korean-led round as "building a third way in AI". Proceeds go to compute, infrastructure, commercial growth and international expansion.

## Why it matters

Europe's champion is becoming a vertically integrated 'neocloud' plus model lab, betting that governments and regulated industries will pay for AI sovereignty.
