This resolves to the community prediction (median) on https://www.metaculus.com/questions/578/human-extinction-by-2100/ as of January 1, 2027.

Will humans go extinct before 2100?

The aggregate of 944 Metaculus community forecasters was 1% on Jul 28, 2023.

Note: predictions on extinction aren't incentive-compatible in any scoring system, and the same is true on Metaculus, but at least the incentive misalignment is not as bad there as on a prediction market.
