Mistral AI raises €1.7 billion led by ASML

Background

On 9 September 2025, Mistral AI announced a €1.7 billion Series C round. ^[1] The round valued the company at €11.7 billion post-money. ^[1] A Series C is a later-stage venture financing round, and post-money valuation is the value assigned to a company after the new investment is included. ^[1] The lead investor was ASML, a Dutch chip-equipment maker, and the two companies formed a strategic partnership. ^[1] ASML said it was lead investor in the round and entered a strategic partnership with Mistral AI. ^[1]

What the round included

Mistral said existing investors DST Global, Andreessen Horowitz, Bpifrance, General Catalyst, Index Ventures, Lightspeed and NVIDIA participated. ^[1] The announcement names ASML as lead investor and gives €11.7 billion as the post-money valuation. ^[1] In venture financing, the lead investor is the investor that anchors and organizes the round; here ASML is named in that role. ^[1] Wikipedia reports that ASML took about an 11% stake. ^[2] That stake figure describes the approximate ownership position attributed to ASML after the round. ^[2]

Independence and research

Mistral said the round reaffirms the company's independence. ^[1] It also said the investment fuels its scientific research to keep pushing the frontier of AI. ^[1] In the announcement, the financing is presented as support for research and for the company's independent position. ^[1] The strategic partnership with ASML sits alongside that statement: ASML is described as lead investor and partner, while Mistral describes the round as reaffirming independence. ^[1]

Why it matters

The transaction links an AI company with a chip-equipment maker. ^[1] ASML's role is both financial and strategic in the announcement: it led the round and formed a partnership. ^[1] The participation of existing investors means the round was not made up only of new money from ASML. ^[1] Wikipedia's report of an approximately 11% stake gives a numerical indication of ASML's position. ^[2]

The announced post-money valuation was €11.7 billion, and the round size was €1.7 billion. ^[1] Mistral linked the investment to scientific research at the AI frontier. ^[1] ASML linked its role to leading the round and to the strategic partnership. ^[1] The round therefore gives Mistral new capital and gives ASML a strategic link to an AI company. ^[1]
