The Anthropic & OpenAI IPOs could mint thousands of new millionaires, & a lot of them plan to give. But how much will actually reach the philanthropic ecosystem? We used Radiant to arrive at a forecast of: $100B+ in pledges, but only ~$26B of it to reach charities by 2031. More below.

Mapping the AI IPO Windfall
Forecasters expect the money to reach charities much slower than the headlines suggest. Here's the map behind the number, and how you can build your own on Radiant, Metaculus’ visual mapping tool.

A recent episode of Hard Fork (@nytimes.com) takes on the much-debated subject of AI forecasting: "I think it’s actually quite interesting and profound that we now have, in some cases, AI systems that are better than humans at making predictions about the future." — @kevinroose.com (1/2)

On Monsanto v. Durnell, our community called Monsanto the favorite (~70-80%); FantasyScotus's crowd leaned 5-4 the other way. We don't often get to compare our forecasts directly against subject matter experts or other crowd aggregation sites, so it's exciting when the opportunity arises.

Interesting difference between Metaculus (a forecast aggregator) and Kalshi (a prediction market) regarding hantavirus… Prediction markets seem to struggle with getting low probabilities right probably because lure of a large return lures in gamblers. There may be other reasons as well.

Whatever you think about the particulars of this story, it demonstrates how prediction markets create perverse incentives far beyond what you initially expect. It’s not hard to imagine the types of pressuring journalists will experience as more people recklessly gamble on real-world events.

Polymarket pulled nuclear detonation markets after public backlash. There's a right way to forecast existential risks and a wrong way. The right way: aggregate judgment for reliable foresight. The wrong way: let anonymous wallets profit from mass death--or worse, corrupt the decisions themselves.
