The legal situation in Brazil

In April 2026 Brazil banned about 27 prediction market platforms, including Polymarket and Kalshi, under a Ministry of Finance directive, with Anatel enforcing the blocks. CMN Resolution 5.298 bars event contracts on sports, politics, entertainment and social events. Contracts on economic indicators remain allowed under financial oversight. Polymarket also lists Brazil as close-only.

Key facts

  • 24 Apr 2026: ban announced; CMN Resolution 5.298 took effect in early May 2026.
  • Anatel enforces ISP blocking.
  • Event contracts on inflation, interest rates, FX and commodities remain permitted.

What are your options in Brazil?

If Polymarket or local law restricts this country, the honest answer is: don't try to get around it. VPNs and third-party wallets break Polymarket's terms, can get funds frozen and may be illegal locally. Look for prediction markets or exchanges licensed by Ministério da Fazenda (Ministry of Finance); Conselho Monetário Nacional (CMN); Anatel (blocking), and check back here: rules change.
