Polymarket Louisiana: A Warning Aimed at Everyone Else

Polymarket Louisiana sits next to one of the country's most heavily taxed sports-betting markets — Louisiana just raised its rate to 21.5% of net revenue in 2025 — and a gaming regulator that has already told the industry event contracts are illegal here. Is Polymarket legal, legit, and safe in Louisiana? The regulator's December 2025 letter is real, but read closely, it was addressed to a different kind of company than Polymarket, and that distinction is the whole story.

Legal status in Louisiana

Louisiana has run a regulated, taxed online sports-betting market since January 2022, licensing eight mobile operators including DraftKings, FanDuel, BetMGM, Caesars and bet365 under the Louisiana Gaming Control Board (LGCB), with mobile wagering live in 55 of 64 parishes (nine opted out in a 2020 local referendum). Governor Jeff Landry signed House Bill 639 on June 18, 2025, raising the tax on net sports-betting revenue from 15% to 21.5%, among the higher rates nationally. On December 5, 2025, LGCB chair Christopher Hebert sent licensees an advisory letter stating that sports event contracts fall "squarely within the state's definition of sports betting" and that the Commodity Exchange Act does not preempt Louisiana law on the point — but the letter was addressed to the state's own licensees and associated vendors, not to Kalshi or Polymarket directly, warning that any licensee that operates, offers or facilitates access to event contracts risks its Louisiana suitability finding. DraftKings, FanDuel and Fanatics, all licensed in Louisiana, subsequently assured the board they would not offer prediction-style products in the state. Polymarket and Kalshi are not Louisiana licensees and hold no Louisiana suitability finding to jeopardize, so the letter has no direct mechanism to reach either platform, and the LGCB has issued no cease-and-desist letter or enforcement action naming Polymarket itself. Attorney General Liz Murrill has publicly voiced concern about prediction markets undercutting the state's regulated, taxed sportsbook industry but had not filed suit against Polymarket as of this writing. Consumer activity has continued regardless: Louisiana-tagged markets on Polymarket have drawn more than $1.6 million in trading volume, and combined Kalshi-and-Polymarket wagering on the 2026 Louisiana Republican Senate primary alone topped $200,000 — none of it subject to the 21.5% tax Louisiana's licensed books pay. Separately, Louisiana Civil Code article 2014 bars courts from enforcing collection on a game-of-chance bet at all: a winner cannot sue to collect what was won, and (absent fraud) a loser who paid voluntarily cannot sue to get it back either. That is a different, older mechanism than the loss-recovery statutes some other states use to let a third party sue on a loser's behalf — Louisiana's rule simply keeps courts out of the wager, in both directions. The international polymarket.com site remains geo-blocked to all US IPs, Louisiana included, under the platform's 2022 CFTC settlement.

State gambling authority: Louisiana Gaming Control Board (LGCB) licenses and taxes sportsbooks; chair Christopher Hebert's Dec. 5, 2025 advisory letter targeted licensees, not Polymarket directly; AG Liz Murrill has voiced concern but has not sued

Louisiana's gaming regulator already told the industry, in writing, that it considers sports event contracts illegal sports betting. Read the letter itself, though, and the company it names is never Polymarket. It names the companies Louisiana can actually discipline — and Polymarket isn't one of them.

Is Polymarket Legal in Louisiana? Start With Who the Letter Names

Louisiana has run a licensed, taxed online sportsbook market since January 2022. Eight operators — DraftKings, FanDuel, BetMGM, Caesars, bet365 and others — take mobile bets in 55 of the state's 64 parishes (nine opted out by local vote back in 2020). Gov. Jeff Landry signed House Bill 639 on June 18, 2025, pushing the tax on net sports-betting revenue from 15% up to 21.5%, one of the higher rates any state charges. That is the market Louisiana actually regulates, and Polymarket has never held a license inside it.

The December 5, 2025 letter, precisely. LGCB chair Christopher Hebert wrote to the board's own licensees and associated vendors — not to Polymarket or Kalshi — stating that event contracts on sports fall "squarely within the state's definition of sports betting" and warning that offering them could jeopardize a licensee's Louisiana suitability finding. DraftKings, FanDuel and Fanatics all confirmed afterward they would not launch prediction products in the state.

Why the Warning Doesn't Reach Polymarket

Suitability findings are a lever Louisiana holds over companies it licenses. Polymarket US (QCX LLC) isn't licensed in Louisiana and has nothing to lose there in that specific sense — the LGCB has no license to threaten and, as of this writing, has sent Polymarket no cease-and-desist letter of its own. Attorney General Liz Murrill has said publicly that prediction markets concern her, framing it as licensed operators playing by rules that platforms like Polymarket skip, but she has not filed a Louisiana case against the company.

The Old Law That Actually Governs a Louisiana Wager

Louisiana Civil Code article 2014 predates all of this by roughly two centuries and cuts a different way than the loss-recovery statutes some other states are using against prediction markets right now. It keeps courts out of a game-of-chance bet on both sides: the winner can't sue to collect, and short of fraud, the loser who paid voluntarily can't sue to get the money back either. There is no Louisiana version of the mechanism a private Charleston attorney used against Kalshi and DraftKings in South Carolina this year — the state simply declines to referee the bet at all.

What's actually happening in Louisiana, by the numbers:

21.5% — Louisiana's tax on licensed sportsbook net revenue, up from 15% as of HB 639 (June 2025)
$1.6M+ — trading volume on Polymarket markets tagged to Louisiana races and events
$200,000+ — combined Kalshi-and-Polymarket volume on the 2026 Louisiana Republican Senate primary alone
0 — cease-and-desist letters the LGCB has sent Polymarket by name

Is Polymarket Legit and Safe in Louisiana?

Legit: Polymarket US runs as a CFTC-designated exchange with KYC accounts and dollar settlement nationwide, and nothing in Louisiana's advisory accuses it of rigging a market or skipping a payout — the fight is over classification, not conduct. Safe: reachable from a Louisiana IP today, under federal oversight rather than the consumer protections Louisiana built specifically into its licensed, 21.5%-taxed sportsbook market. That framework was written for DraftKings and FanDuel, not for a CFTC exchange sitting outside it.

None of this is a way to make money, in Louisiana or anywhere else — an event contract can expire worthless regardless of which agency eventually wins the argument over what to call it. 21+ only, and if it stops feeling like a choice, 1-800-GAMBLER is free and confidential.

Polymarket Louisiana — Frequently Asked Questions

Is Polymarket legal in Louisiana?

Louisiana has never licensed Polymarket, and its Gaming Control Board considers sports event contracts to be sports betting under state law. But the board's December 2025 advisory letter was addressed to its own licensees — DraftKings, FanDuel, Fanatics and similar operators — warning them off event contracts, not to Polymarket or Kalshi, which hold no Louisiana license to lose. No cease-and-desist or lawsuit has been filed against Polymarket by name.

Did Louisiana's December 2025 letter ban Polymarket?

Not directly. LGCB chair Christopher Hebert's letter told licensed sportsbooks and their vendors that offering or facilitating sports event contracts could jeopardize their Louisiana suitability finding. DraftKings, FanDuel and Fanatics all confirmed they would not offer prediction markets in the state as a result. Polymarket was never a Louisiana licensee, so that specific enforcement lever does not apply to it the way it applies to a licensed book.

Is Polymarket legit in Louisiana?

Polymarket US (QCX LLC) operates nationwide as a CFTC-designated exchange with KYC-verified accounts and dollar settlement, and nothing in Louisiana's regulatory letter alleges misconduct — it's a classification dispute about whether event contracts are sports betting, not a fraud claim. More than $1.6 million has traded on Louisiana-tagged markets, evidence people are using it, not evidence it operates any differently there than elsewhere.

Is Polymarket safe to use from Louisiana right now?

Mechanically, yes — no injunction or geoblock stops a Louisiana IP from reaching Polymarket US, and Attorney General Liz Murrill has raised concerns publicly without filing a case. "Safe" here means federal CFTC oversight, not the consumer protections Louisiana built into its licensed, 21.5%-taxed sportsbook market, because that framework was never extended to prediction markets.

Could I get sued in Louisiana for using Polymarket?

Louisiana's rule runs the opposite direction from states with third-party loss-recovery statutes. Civil Code article 2014 keeps courts out of game-of-chance wagers entirely: a winner cannot sue to collect, and a loser who paid voluntarily generally cannot sue to get it back either, absent fraud. There is no Louisiana equivalent of the statute a private citizen used to sue over prediction-market losses in South Carolina.

Why does Louisiana care about a platform it can't license?

Money. Louisiana's licensed sportsbooks paid the state a 21.5% tax on net revenue after House Bill 639 raised the rate in mid-2025 — one of the country's higher rates. Combined Kalshi-and-Polymarket betting on just the 2026 Louisiana Senate primary topped $200,000, all of it outside that tax base. The December advisory protects licensed operators' footing; it does not currently touch the untaxed volume trading next to them.
