Polymarket Open Interest Hits Yearly High, with Sports, Politics, and Crypto Leading the Way
BlockBeats News, December 17th, according to Dune Analytics, the open interest of the prediction market Polymarket has been continuously rising throughout the year, recently hitting a new yearly high of approximately $326 million, representing a growth of nearly 170% from the beginning of the year when it was around $120 million. In terms of market structure, the sports, political, and crypto sectors hold the top three positions in market share at 46.6%, 21.12%, and 12.4% respectively. Additionally, due to a significant amount of market settlement at the end of each month, about one-third of open interest contracts are closed at month-end.
Polymarket had previously set a historical record of $410 million in total open interest during last year's November U.S. election period, with $385 million coming from the political sector. In Bitwise's Top Ten Crypto Market Predictions for 2026 released yesterday, it was mentioned that next year, Polymarket's open interest will reach a new all-time high, surpassing the 2024 U.S. election levels.
