Coefficient Giving — Description: Cumulative AI safety grants (2017-2024): $336M (~12% of total giving)

NoteThe source text directly confirms the claim. The exact passage states: 'Since it was founded in 2017, Open Phil has donated about $2.8 billion of which about $336 million was spent on AI safety (~12%).' This matches all three components of the claim: (1) $336M in cumulative AI safety grants, (2) the 2017-2024 timeframe (Open Phil founded in 2017, source updated January 2025 with 2024 data), and (3) ~12% of $2.8B total giving. The source is the LessWrong post cited in the claim's additional context.

NoteWhile the source URL matches the LessWrong post cited in the claim's context, the provided excerpt does not contain the specific numerical claims about Coefficient Giving ($336M) or the percentage (12% of $2.8B). The excerpt only provides introductory material and historical context about AI safety funding estimates from 2017-2020. To verify this claim would require access to the complete article, particularly any tables or sections discussing individual grantmakers like Coefficient Giving.
