Trump contract buying causes brief mispricing on Polymarket

Polymarket experienced a brief mispricing when an individual or entity purchased over 4.5 million Trump contracts for the 2024 Presidential Election, causing the odds to reach 99% due to the mechanics of the order book. This highlights how large trades can temporarily skew betting odds on prediction platforms, despite the actual market odds being around 63% at the time. Data shows that Republican Donald Trump's presidential victory odds on Polymarket spiked to 99% for one entity briefly on Friday due to their constant buying, resulting in a temporary mispricing in the order book.
