[Arkham Launches Prediction Market Trader Ranking System] According to The Block, on-chain analytics platform Arkham has launched a prediction market trader ranking system, utilizing an Elo/MMR-style scoring mechanism to rank traders based on prediction accuracy. Each correct prediction increases a trader's Elo score, with low-odds correct predictions yielding higher score growth compared to high-odds ones. Unlike profit-and-loss rankings, this system prioritizes accuracy over the scale of funds invested, meaning small-scale traders with higher win rates can surpass wealthier traders with lower accuracy. The current rankings primarily focus on Polymarket traders, with the top-ranked trader 'GardenerCx' employing a '5-minute crypto price movement market' strategy, achieving a 64.3% win rate across 2,644 bets.
