French AI startup Mistral valued at over 21 billion euros after latest funding

French AI company Mistral announced Tuesday that it had raised three billion euros ($3.5 billion) in what it described as the largest-ever European tech fundraising, valuing the startup at over 21 billion euros. While still an upstart compared to the AI giants OpenAI or Anthropic, Mistral says it is carving a niche by offering models that companies can run themselves with their own data.
