The “Will Donald Trump win the 2024 US Presidential Election?” market on Polymarket processed over $3.6 billion in trading volume between its launch in early 2024 and the election’s resolution in November. It became the largest single prediction market in history by an enormous margin. For comparison, the previous record-holder — a 2020 election market on PredictIt — had processed approximately $25 million.
The volume was driven by a combination of crypto-native traders, institutional money testing the platform, and a wave of retail speculators who had discovered prediction markets during the election cycle. Throughout October 2024, daily trading volume on the Trump market often exceeded $50 million. On election day itself, real-time volume crossed $100 million in a single day as traders adjusted positions based on early returns.
The depth of the market was as impressive as the total volume. At any given moment in the final weeks, traders could buy or sell millions of dollars without significantly moving the price. This deep liquidity was unprecedented for a prediction market and demonstrated that the platform could absorb institutional-scale trades. Polymarket had finally reached the volume threshold where it functioned like a real financial market.
The election volume created lasting infrastructure. After November, Polymarket retained a significant portion of the user base and trading activity that had flowed in for the election. Markets on sports, geopolitics, crypto prices, and pop culture all saw increased activity. The election had been the catalyst, but the platform was now permanently in the consciousness of mainstream finance. The $3.6 billion was a moment that would shape prediction markets for years.
