A significant trading event occurred on Polymarket, where an individual purchased over 4.5 million Trump contracts related to the 2024 Presidential Election, resulting in odds spiking to 99% for part of the purchase. This mispricing occurred due to low liquidity and large trade volumes, even though actual market odds were around 63%. The trader, identified by the account 'GCorttell93', spent over $3 million in a short time, with a specific tranche of $275,000 filled at the inflated 99% odds. Polymarket operates on a blockchain-based order book, meaning that large buy orders can temporarily skew the betting odds. This market for the election winner stands out as the largest volume market on Polymarket, with transactions exceeding $2.2 billion, indicating strong market interest in the potential outcomes of the election.
