Andrii Bilous is the founder of NeuPortal (neuportal.ai), an AI forecasting lab running a public accountability experiment: every AI forecast is locked before the event, anchored into Bitcoin via OpenTimestamps, benchmarked against prediction-market prices frozen at the same instant, and Brier-scored in public — losses included. He writes about forecasting literacy, probability calibration, and why AI predictive claims should be verifiable by default. The live scoreboard, currently covering the 2026 World Cup, is public at neuportal.ai/experiment.
