A trading strategy focusing on arbitrage in Bitcoin prediction markets has reportedly turned an initial $50 investment into $280,000 within three weeks. The approach exploits a temporary lag between real-time Bitcoin price data on Binance and odds updates on Polymarket's 15-minute BTC "up or down" prediction markets. Traders buy the winning side before the odds adjust, capitalizing on a 30-90 second delay. The strategy is fully automated and does not involve alternative markets, but its effectiveness may diminish as the lag closes.
