News Summary

• The Treasury Department announced on October 21, 2026 that its Office of the Comptroller of the Currency has issued a final rule implementing the payment-stablecoin law signed in 2025.
• The rule sets standards for stablecoin issuers, including reserve requirements and issuance parameters, giving firms roughly two months to comply before the January 2027 effective date.
• The effective date gives prediction markets a natural resolution point, and contracts on Bitcoin’s price around the turn of 2027 were already active as the rule landed.
