Polymarket Washington, D.C.: The District That Asks Congress

Polymarket Washington, D.C. runs into a wrinkle no state page on this site has to deal with: the District isn’t a state, and when DC legalized its own sports betting in 2019, the law itself had to sit in front of Congress for a review period before it could take effect. Is Polymarket legal, legit, and safe for a DC trader? The answer runs through a jurisdiction that already knows what it feels like to have a federal body decide whether its gambling law stands — which makes the CFTC-versus-states fight over Polymarket look a little different from here.

Legal status in Washington, D.C.

The District regulates its own sports wagering under the Sports Wagering Lottery Amendment Act of 2018 (D.C. Law 22-312), which the DC Council passed in December 2018 and Mayor Muriel Bowser signed January 23, 2019. Because DC operates under the Home Rule Act rather than state sovereignty, that law couldn't simply take effect on signature — it was transmitted to Congress on February 7, 2019 for a mandatory review period, the same process every DC bill goes through, and became law May 3, 2019 once that window closed without objection. No US state submits its gambling statute to Congress for a veto window; DC does it by constitutional design. The District's underlying gambling code sits in DC Code Title 22, Chapter 17, a criminal statute that predates any of this and was never written with a CFTC-designated exchange in mind. On the operator side, DC's market has already been rebuilt once: the DC Lottery's own app, GambetDC, launched May 2020 through a no-bid Intralot contract, and for years only GambetDC could take mobile bets citywide — competing operators like DraftKings and Caesars were geofenced to within two blocks of partner venues such as Capital One Arena or Nationals Park. The DC Council ended that structure in its FY2025 budget, passed June 2024, and FanDuel replaced GambetDC as the Lottery's own-brand partner in April 2024 while BetMGM and Caesars launched district-wide that July, DraftKings following later in July via a market-access deal with DC United, and Fanatics in September 2024 through the Washington Spirit. The DC Office of Lottery and Gaming (OLG), housed inside the Office of the Chief Financial Officer, licenses all of them under Class A, B and C tiers. None of that licensing structure mentions event contracts or prediction markets. Separately, DC Attorney General Brian Schwalb has put the District's name on two national positions in 2026: the 38-state amicus brief filed in April backing Massachusetts's lawsuit against Kalshi, arguing state gambling authority reaches CFTC-designated sports contracts regardless of federal registration — a theory that would apply to Polymarket US exactly the same way it applies to Kalshi — and a 44-state comment letter to the CFTC arguing the agency lacks authority to preempt state gambling law over sports event contracts generally. Neither document is a DC-specific lawsuit or cease-and-desist naming Polymarket, and DC is not among the roughly nine states — Arizona, Connecticut, Illinois, New York, New Mexico, Minnesota, Rhode Island, Wisconsin, Kentucky — where the CFTC has sued to block state enforcement this year. Polymarket US, run by QCX LLC under CFTC designation, is reachable from a DC IP today. The international polymarket.com site remains geo-blocked for all US IPs, DC included, under the unrelated 2022 CFTC settlement.

State gambling authority: DC Office of Lottery and Gaming (OLG), within the Office of the Chief Financial Officer, licenses sports wagering under the Sports Wagering Lottery Amendment Act of 2018; Attorney General Brian Schwalb has signed two 2026 multistate positions against CFTC preemption of state gambling law but filed no DC-specific action against Polymarket

Every other jurisdiction on this site legalized sports betting on its own authority. Washington, D.C. couldn't. When the DC Council passed the Sports Wagering Lottery Amendment Act in December 2018, the bill still had to sit in front of Congress for a review period before it became law — a step no state government answers to. That history is worth knowing before asking whether Polymarket is legal, legit, and safe here, because DC has already run the exact experiment the CFTC fight is now running everywhere else: what happens when a federal body gets to decide whether local gambling law stands.

Is Polymarket Legal in DC? Start With Who Gets to Decide

The DC Council passed the Sports Wagering Lottery Amendment Act of 2018 (D.C. Law 22-312) that December; Mayor Muriel Bowser signed it January 23, 2019. Under the Home Rule Act, that wasn't the end of the process — the law was transmitted to Congress on February 7, 2019 for a mandatory review window, and only became effective May 3, 2019 once that period closed without a disapproval resolution. DC's general gambling statute, DC Code Title 22, Chapter 17, sits underneath all of that as older criminal law, and neither it nor the 2018 Act was written with a CFTC-designated event-contract exchange in the room.

DC's sports-betting law, in order:

Dec 2018 — DC Council passes the Sports Wagering Lottery Amendment Act
Jan 23, 2019 — Mayor Bowser signs it
Feb 7 – May 3, 2019 — mandatory congressional review period, then effective
May 2020 — GambetDC, the Lottery's own app, launches via a no-bid Intralot contract
Apr 2024 — FanDuel replaces GambetDC as the Lottery's partner
Jun 2024 — DC Council ends FanDuel's citywide exclusivity in the FY2025 budget
Jul–Sep 2024 — BetMGM, Caesars, DraftKings, Fanatics all launch district-wide

The Irony DC Can't Avoid

DC Attorney General Brian Schwalb has put the District's name on two 2026 positions arguing that federal designation shouldn't let a company override state gambling authority: the 38-state amicus brief backing Massachusetts's lawsuit against Kalshi in April, and a 44-state comment letter telling the CFTC it lacks authority to preempt state law over sports event contracts. The same reasoning would apply to Polymarket US, which lists sports-adjacent contracts under the identical CFTC designation Kalshi relies on. It's a clean legal position — except DC's own sports-betting law only exists because a federal body, Congress, was given the final say over it first. The District is arguing against federal override in one direction while having lived under it in the other.

Neither brief is DC-specific enforcement. No DC lawsuit, cease-and-desist, or OLG advisory names Polymarket. DC also isn't among the roughly nine states — Arizona, Connecticut, Illinois, New York, New Mexico, Minnesota, Rhode Island, Wisconsin, Kentucky — where the CFTC has sued this year to block state enforcement against prediction markets. DC simply hasn't acted on its own yet, in either direction.

DC Already Rebuilt Its Sportsbook Market Once

The District isn't new to changing its mind about market structure. GambetDC, the Lottery's in-house app, launched in May 2020 under a no-bid Intralot contract and initially had the District's mobile market to itself — competitors were geofenced to within two blocks of partner venues like Capital One Arena or Nationals Park. The DC Council scrapped that in its FY2025 budget, passed June 2024: FanDuel took over as the Lottery's own-brand partner that April, and BetMGM, Caesars, DraftKings and Fanatics all launched citywide between July and September 2024. None of those five licenses says anything about event contracts, and none of them is what Polymarket US operates under.

Is Polymarket Legit and Safe in DC?

Legit: unchanged by geography. Polymarket US runs under the same CFTC designation, KYC, and dollar settlement in DC as anywhere else, and nothing about the District's congressional-review history or its AG's brief-signing questions whether it pays out. Safe: an account opens today with nothing DC-specific blocking it, but that safety is federal oversight, not an OLG license — the consumer protections built around FanDuel, BetMGM, Caesars, DraftKings and Fanatics as Class A/B/C operators don't extend to an exchange sitting outside that structure.

A jurisdiction that has already had Congress rule on its own gambling law isn't obviously more or less likely to see a ruling on Polymarket next — it just means DC has lived this exact federal-versus-local question before. This is not a way to make money, and a contract can still expire worthless no matter how that question resolves. 21+ only; the DC Department of Behavioral Health operates a problem gambling helpline for District residents.

Polymarket Washington, D.C. — Frequently Asked Questions

Is Polymarket legal in Washington, D.C.?

No DC statute, court order, or OLG advisory names Polymarket, and the District hasn't sued it the way Michigan or Washington state sued Kalshi. But DC's Attorney General has signed two 2026 multistate positions arguing the exact legal theory Polymarket US relies on — CFTC designation — doesn't override state gambling authority. That's a stated position, not a ruling, and it hasn't turned into DC-specific enforcement.

DC's own sports-betting law needed congressional review — does that make Polymarket's situation different here?

It's a real structural difference, even if it doesn't change the legal answer. Every state that licenses sports betting does it under its own sovereign authority. DC can't — the Sports Wagering Lottery Amendment Act of 2018 only became law after sitting in front of Congress for a review period under the Home Rule Act, from February to May 2019. That history means DC has literally already lived the question the CFTC fight is now asking everywhere else: does federal authority get the last word over a jurisdiction's own gambling law? DC's answer, for its own sportsbook law, was yes. For Polymarket, DC's AG is currently arguing no.

Has DC taken any action against Polymarket or Kalshi?

Not directly. Attorney General Brian Schwalb joined the 38-state amicus brief backing Massachusetts's lawsuit against Kalshi in April 2026 and a separate 44-state comment letter telling the CFTC it lacks authority to preempt state gambling law over sports event contracts. Both are coalition positions that name Kalshi or the CFTC rule, not a DC lawsuit or cease-and-desist against Polymarket specifically.

Is Polymarket legit in DC?

As a company, that doesn't change by jurisdiction: Polymarket US runs under the same CFTC designation, KYC process, and dollar settlement in DC as anywhere else. DC's open question is jurisdictional — whether the District's gambling authority, itself subject to congressional review, reaches a federally designated exchange — not whether Polymarket honors a resolved contract.

Is Polymarket safe to use from DC right now?

Mechanically, yes — a DC IP can open a Polymarket US account today with nothing blocking it, and DC isn't among the states where a court has ordered geofencing. But "safe" here means CFTC oversight, not an OLG license; the District's consumer protections were built around its own Class A/B/C sportsbook operators, not an exchange sitting outside that licensing structure.

Does DC have its own licensed sportsbook I could use instead?

Yes, and it's a real multi-operator market now. DC has licensed online sports betting since 2019, and after the DC Council ended FanDuel's citywide exclusivity in its FY2025 budget, FanDuel, BetMGM, Caesars, DraftKings, and Fanatics all hold current OLG licenses as of 2024–2026. That's a state-licensed sportsbook in the traditional sense — a different product and a different legal footing than Polymarket's federally designated event contracts.
