The identified funding announcement does not establish €21 billion

Mistral’s September 9, 2025 announcement records a €1.7 billion Series C at an €11.7 billion post-money valuation, led by ASML. This is a dated milestone, not proof of the video headline’s €21 billion figure. A later transaction or other explicit valuation source is needed before that headline can be treated as established. This source also does not establish that every founder came from Meta.
