Methodology
Figures aggregate the active markets WeeBet syncs from Polymarket and Kalshi (refreshed about every 30 minutes). Volume and liquidity are summed from each platform's reported per-market figures; “biggest markets” ranks tradeable markets (priced 5–95%) by 24-hour volume. Platforms report volume differently, so treat cross-platform comparisons as directional. See the underlying contracts on live markets.
