Mistral AI, the French startup that has become Europe’s most prominent answer to OpenAI, is looking to raise roughly €3 billion in fresh funding at a €20 billion valuation. If the round closes, it would represent a massive leap from the company’s €11.7 billion post-money valuation just months ago.
From zero to €20 billion in three years
Mistral AI was founded in 2023 by Arthur Mensch, Guillaume Lample, and Timothée Lacroix, all of whom brought serious pedigree from stints at Meta and Google DeepMind.
In June 2024, Mistral completed a €600 million Series B that valued the company at €5.8 billion. Then came September 2025, when the company pulled in €1.7 billion in a Series C round. That round was led by ASML, the Dutch semiconductor equipment giant, which picked up an 11% stake for €1.3 billion.
The roster of backers includes Nvidia, Andreessen Horowitz, General Catalyst, and Bpifrance, the French public investment bank. By early 2026, Mistral’s cumulative equity funding had exceeded €2.8 billion, and the company had also tapped debt markets, securing $830 million in March 2026 specifically earmarked for data center expansion in the Paris area.
