A viral trading bot marketed as a 'Polymarket Arbitrager' has left users disappointed, failing to deliver the promised profits. The bot, which claimed to exploit arbitrage opportunities in binary markets by identifying discrepancies where the sum of YES and NO prices was less than $1, was fundamentally flawed. Polymarket's structure ensures that YES + NO must equal or exceed $1, making such arbitrage impossible. Users reported that the bot's strategy was ineffective due to market price changes occurring between orderbook checks, leading to incorrect trades. While the bot occasionally profited from market volatility, this was not true arbitrage. The experience highlights the risks of relying on automated trading solutions without thorough verification of their strategies. Traders are advised to exercise caution and consider more reliable methods for identifying profitable opportunities.
