Episode Details

Polymarket’s crypto betting system was exposed as vulnerable to manipulation, where savvy traders exploited a single-price snapshot at settlement to artificially inflate or deflate prices, siphoning millions from unsuspecting retail users. Researchers traced suspicious, high-speed trades on exchanges like Binance right before settlement, followed by sharp reversals — though they couldn’t confirm direct links, the losses overwhelmingly hit everyday traders. The fallout sparked widespread criticism over the platform’s flawed design, likened to a rigged game. In response, Polymarket is overhauling its settlement mechanism by adopting a time-weighted average price (TWAP) across different timeframes — 30 seconds for 5-minute markets, 60 seconds for longer ones — powered by Chainlink Data Streams. This change aims to level the playing field and restore trust, backed by a $1 million liquidity incentive to ease the transition.
