Arkham launches onchain prediction market trader ranking by

Arkham has launched a ranking system aimed at surfacing the best-performing prediction market traders onchain. The system prioritizes accuracy over the size of positions or total earnings, so smaller wallets with strong win rates can outrank larger traders whose absolute profits come from bigger wagers.

Why it matters

Prediction market leaderboards have historically rewarded capital deployed, not correctness. Arkham's accuracy-weighted ranking reframes the metric: a trader who hits 70% of small bets can climb past a whale whose win rate sits at 55% on seven-figure positions. For copy-trading products and signal feeds that pull from these rankings, the shift tilts the discovery layer toward edge rather than size.

Market impact

Onchain analytics platforms are increasingly competing on trader-intelligence products, and prediction markets have been the fastest-growing segment to instrument. A leaderboard that surfaces sharp wallets by hit rate is more usable for the retail copy-trading audience than P&L tallies, and it gives prediction market venues a cleaner signal to plug into their own retention funnels.
