Arkham Launches Prediction Market Trader Ranking System

CoinFeed, June 30 – According to The Block, on-chain analytics platform Arkham has launched a prediction market trader ranking system that uses an Elo/MMR-style rating mechanism to rank traders based on prediction accuracy. Each correct prediction increases a trader's Elo score, with correct low-odds predictions yielding higher score gains than high-odds ones. Unlike profit/loss rankings, the system prioritizes accuracy over capital size, meaning small traders with higher win rates can outperform well-funded but less accurate traders. Currently, the ranking focuses mainly on Polymarket traders. The top-ranked trader, 'GardenerCx,' employs a '5-minute crypto up/down market' strategy and has achieved a 64.3% win rate across 2,644 bets.
