Mistral AI has closed a €3 billion Series D round led by Samsung Electronics, reaching a post-money valuation of more than €21 billion and nearly doubling its €11.7 billion valuation from its September 2025 Series C. The company claims this is the largest equity fundraising ever completed by a European technology company, though that characterization comes from Mistral itself and has not been independently verified by a public registry. Proceeds are directed toward frontier research, expanded compute capacity, data center infrastructure, and international commercial growth, with CEO Arthur Mensch projecting owned compute capacity to grow approximately 100% over five years.

Nebius Group filed a Form 6-K on September 8, 2026, confirming Palantir Technologies has designated it as preferred sovereign-AI infrastructure partner, with plans to integrate Nebius compute and inference endpoints inside the Palantir enterprise perimeter for eligible commercial customers. The partnership structure allows customers to deploy open models while retaining control over their compute, data, and models, though no contract value, guaranteed spend, integration completion date, or specific geographic eligibility criteria were disclosed. Nebius's broader Q2 2026 figures — including more than $40 billion in customer commitments and a target of 5 GW of contracted power by year-end — reflect company-wide capacity and cannot be attributed to this partnership specifically.

The Justice Department filed a Statement of Interest on September 1, 2026, urging the court to reject any categorical rule that training large language models on copyrighted works is unlawful. Across all four statutory fair-use factors, the DOJ characterized the training process as 'exceedingly or extraordinarily transformative,' distinct from later model outputs, and unlikely to substitute for or expose protected works to the public. The filing also warns that broad copyright liability for AI training could harm competition and U.S. national-security capabilities, though the government took no position on whether a licensing regime would be feasible.
