I saw this tweet by Pedro Domingos and thought to myself, "one of those things is an implicit prediction."

Update 2025-04-03 (PST) (AI summary of creator comment): Baseline Valuations for 2023:
Anthropic: An accepted valuation of $18.4 billion from its December 2023 fundraising round.
OpenAI: An accepted valuation of $80 billion from its secondary sale initiated in October 2023 (accepted in February 2024).
These values will be used as the 2023 benchmarks for resolving the market, subject to revision if credible alternative figures are provided before finalization.
@sophiawisdom Anthropic sought to raise with a valuation of $18.4 billion in December 2023, which was accepted when the round closed a few weeks later. So $18.4 billion for Anthropic.
OpenAI sought a secondary sale with a valuation of $80 billion in October of 2023, which was accepted February 2024. So $80 billion for OpenAI.
Before I lock in these numbers, does anyone have better numbers they think I should use?
@rogs Yes, that's correct. I'll look for the most credible valuation for both at the end of 2023. For example, let's say $80 billion for OpenAI and $18.4 billion for Anthropic. If at any time either company has a credible valuation that drops below that, I'll resolve YES.
