What This Means for Kalshi vs. Polymarket in District of Columbia

Both Kalshi and Polymarket currently treat District of Columbia the same way as most of the country: standard signup and funding, with no state-specific restriction reported on either platform. Kalshi and Polymarket US are both CFTC-regulated exchanges, and neither has a legal advantage over the other in this dispute — state actions in this category name multiple platforms at once, not one company exclusively.

Why Is This Even Contested? The Federal-vs-State Fight

Prediction markets sit at the intersection of two legal regimes that currently disagree. Kalshi and Polymarket US register their contracts with the CFTC as swaps or event contracts on a federally designated exchange, and argue that federal law preempts conflicting state gambling law. State gaming regulators counter that sports-related contracts — betting on who wins a game, a point spread, or a player prop — are functionally sports betting, which most states require a separate license to offer. Federal appellate courts are currently split: the Third Circuit ruled for Kalshi on preemption grounds (April 6, 2026), while a federal judge in the Southern District of New York ruled against Kalshi on the same underlying question (July 8, 2026). This is genuinely unresolved law, not a settled "CFTC means legal everywhere" fact — treat any claim that federal registration alone guarantees legality in every state with skepticism.

No known dispute of either kind.
