Future of Life Institute (FLI) — Grant Received: $666M

NoteThe source directly confirms the exact stored value of $665.8 million (665,800,000) as of 2021. The Wikipedia infobox explicitly lists 'Endowment $665.8 million (in 2021)' which matches the claim's exact stored value. The source also confirms Vitalik Buterin as the donor in July 2021. The claim's rounded display value of '$666M' is within normal rounding tolerance of $665.8M. The additional context about ~$500M being cashed out in March 2026 and transfer to a donor-advised fund is not addressed in the source, but the core claim about the $665.8M grant received as of 2021 is directly confirmed.
