Brazil's Finance Minister Dario Durigan announced blocking 27 prediction‑market platforms, including Kalshi and Polymarket, citing gambling concerns.
Telecom regulator Anatel disabled the sites by Friday afternoon after the National Monetary Council restricted derivatives linked to non‑economic events.
The council now permits derivatives only on pre‑defined economic benchmarks such as price indices, interest rates and exchange rates.
Economic reforms secretary Regis Dudena noted prior law allowed betting only on sports and online games, calling the platforms “destructive gambling.”
