OddsBridge tracks every bet imported from Polymarket and Kalshi against the market belief 30 minutes before resolution — the closing line. Users who opt in to this public leaderboard surface their lifetime edge over that closing line plus their realised ROI and win rate. No wallet addresses, no real names — just the first 8 characters of each tracker key. The ranking requires 20+ settled CLV-eligible bets to filter out statistical noise. Sort priority: edge over close, then beat-close rate, then sample size.
No opt-in users yet meet the 20-bet floor.
Import your Polymarket or Kalshi history at /account/tracker, then toggle "Join public sharpness leaderboard" to enter.
Edge vs close = (placedDecimalOdds − closingDecimalOdds) / closingDecimalOdds × 100. Positive means the user got better odds than the market 30 minutes before resolution — the closing line. Beat close rate is the fraction of settled CLV-eligible bets with a positive edge. We require 20+ such bets per user before listing them so small-sample noise doesn't dominate.
The closing line itself comes from OddsBridge's tick collector for the markets we track, plus on-demand derivation from Polymarket's CLOB and Kalshi's candlestick API for everything outside that coverage. We pin the closing line to a tick that's at least 30 minutes pre-resolution and still in the (0.02–0.98) uncertainty zone — so the comparison reflects market belief before info shocks or resolution imminence start dragging the price toward 0 or 1.
Edge vs close ≠ ROI. A bet at $0.20 on something the market still rated $0.50 at T-30min shows +150% edge — whether or not the outcome actually paid out. ROI is the column on the far right and reflects realised P&L. A genuinely sharp trader tends to be positive on both; high edge with negative ROI usually means a long-shot strategy that prints CLV but loses outright.
