# Mistral AI scaling, sovereign AI push deepens > Live situation record from CLSTR: https://clstr.news/situations/mistral-ai-european-ai-funding-round > Updated: 2026-09-15T21:41:34.000Z. Sources: 187. Developments: 20. Following its €3 billion Series D funding round in early September, Mistral AI has expanded its enterprise and industrial footprint through new strategic partnerships. On September 14, Mistral partnered with Cloudera to provide secure, sovereign AI for large enterprises in regulated industries. The collaboration integrates Mistral’s models with Cloudera’s hybrid data platform, enabling organizations to run inference across public cloud, private, on-premises, or air-gapped systems without moving sensitive data outside existing security boundaries. On September 15, TotalEnergies announced a three-year, €100 million partnership with Mistral to develop specialized language models for oil and gas exploration. The companies will establish a joint scientific laboratory to combine geoscientific expertise with Mistral’s infrastructure, aiming to analyze massive datasets to accelerate decision-making in reservoir exploration. CEO Arthur Mensch noted the collaboration demonstrates the strength of “European industrial and digital capacities.” ## Claims - Mistral AI raised 3 billion euros in a Series D funding round.
