Mistral AI has raised €3 billion in a Series D funding round at a post-money valuation of more than €21 billion, which the French AI company said was the largest equity fundraising round ever completed by a European technology firm.

The round, announced this week, was led by Samsung Electronics, with Scaleup Europe Fund, managed by EQT, and existing investor PSG Equity acting as co-leads. New investors Advent, funds and accounts managed by BlackRock, and the Grand Duchy of Luxembourg also joined, alongside existing backers a16z, ASML, Belfius, BNP Paribas CIB, Bpifrance, Carmignac, DST Global, Eurazeo, General Catalyst, Headline, Hillspire, Index Ventures, Korelya Capital, Lightspeed, NVIDIA, Phoenix Court's Solar fund and Salesforce Ventures. Mistral said the funding would expand its frontier research and compute capacity, and accelerate commercial growth internationally.

The company, which launched three years ago, said it now operates across 20 countries and supports more than 125 global enterprises, including Airbus, ASML and HSBC. Mistral described itself as the only AI company building a full stack of open-weight models, infrastructure and products together, saying this approach means customers are never locked into a single vendor's roadmap or pricing.

Mistral framed the raise around what it called a shift in enterprise and government priorities, from simply building the most powerful model toward retaining control over data, models, compute and production systems.

Swiss Cheese Defences- Identity fraud goes industrial and off-the-shelf
Ofer distinguishes between two current attack patterns: highly sophisticated, professionally coordinated deepfake and injection attacks designed to beat detection outright, and a much larger volume of lower-effort, high-scale attempts that rely on bombarding systems rather than disguising themselves well. He argues the real story right now is industrialisation of scale rather than uniform improvement in quality, though both are accelerating in parallel. The conversation covers why agentic AI is opening a new front in identity fraud, particularly the unresolved problem of tying an AI agent’s identity back to the human who deployed it and the permissions it holds. Ofer is candid about the current state of agent defences, describing them as underdeveloped and easy to hijack or poison, comparing the current state of play to Swiss cheese. He also discusses cross-industry fraud detection, including how signals, rather than raw data, are now being shared across platforms including AU10TIX and Reality Defender to surface fraud rings invisible to any single organisation. The conversation also covers explainability as one of AI’s most underdeveloped capabilities, with Ofer arguing that flagging a session as fraudulent without a credible, defensible reason will increasingly run into regulatory and practical limits. Elsewhere, the discussion covers credential laundering and the manufactured construction of fake digital histories and footprints, and the shift toward digital ID wallets that Ofer believes will make physical document fraud increasingly rare. He closes on what he calls “agentic avatars,” AI systems capable of holding a full visual and verbal conversation on someone’s behalf, and why he expects identity verification to have to become genuinely immersive across every form of media as a result.
