Polymarket's weekly trading volume soars to $4B, expanding US market share amid regulatory recovery

Polymarket, a prediction market operator, saw its combined weekly trading volume jump from $200 million a year ago to over $4 billion in July 2026, driven by growth on both its US and international platforms. After halting US contracts in 2022 due to regulatory issues, Polymarket relaunched in the US in early 2026 and has since gained 12% market share and led app downloads. The company, valued at $21 billion, earns mainly from transaction fees and is exploring growth in sports contracts, institutional adoption, and data monetization. However, regulatory and legal risks remain, with potential Supreme Court involvement on sports event contract legality.

Polymarket's recent surge in US trading volume provides context for market activity.
