Forecast methodology: Progress % and predicted years are computed by our proprietary algorithm combining real-money prediction markets (Polymarket, Kalshi), expert forecasts weighted by Brier score accuracy, and hard data trend extrapolation using S-curves fitted to clinical trial progression (ClinicalTrials.gov), AI benchmark scores (HuggingFace), publication velocity (arXiv), and drug approvals (openFDA). P10/P50/P90 represent optimistic, median, and pessimistic scenarios. Updated hourly.
