Polymarket US hits $8.7B volume as Coinbase and Roundtable push USDC media payments

  • —Polymarket US 30-day notional volume hit $11.8 billion as of mid-October 2026
  • —Weekly volumes rose to $2.7–3.1 billion from $60 million earlier in 2026
  • —Sports contracts make up 98% of Polymarket trading, led by NFL and college football
  • —Roundtable plans to migrate ~$100 million in annual ad revenue from 21 media brands to USDC
Why it matters: Sports-heavy volumes blur the line between prediction market and sportsbook, while USDC ad payments widen stablecoin use in media.
