Sources: settlements and events from Polymarket's public Gamma API; odds 24 hours before close (the earlier of the scheduled end and the actual close) from Polymarket's public CLOB price history. A “—” means the price history doesn't prove it, so that event is left out of the favorite count rather than estimated.
