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.

3/ In a comment left in the Labor Automation Hub, Pro Forecaster Haiku called both moves "unprecedented” -- going from “impossible” to “twice in one month.” Haiku therefore raised their odds of a "Pause World," the scenario where regulation slows AI adoption enough for labor markets to catch up.

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.
