The contrast with the United States is striking. While Brazil and much of Europe are moving toward outright bans or strict licensing requirements, the US remains mired in a fragmented regulatory battle between federal agencies and individual states over whether prediction markets constitute gambling or legitimate financial instruments. The CFTC has filed lawsuits defending its exclusive jurisdiction over platforms like Kalshi against state-level enforcement actions, and the issue may ultimately reach the Supreme Court. Brazil's decisive and broad-based shutdown — covering both international giants and local platforms in a single regulatory move — represents the kind of unified national response that the US has so far been unable to deliver, and it may add pressure on American regulators to resolve the jurisdictional uncertainty before more countries simply opt for prohibition.
