South Dakota Betting

South Dakota has the smallest geographic betting market in the country: a bet may lawfully be placed only on the premises of a licensed gaming establishment inside the city limits of Deadwood, and at tribal casinos whose compacts allow it. The statute requires an operator to install equipment "to ensure that all bets are placed on the premises", and even the product the law calls advance deposit sports wagering is an on-premises product whose account must be opened in person in Deadwood. The geographic limit sits in the state constitution rather than in a statute: Deadwood is named in Article III, so widening the market beyond it requires a vote of the electors, not merely a bill. The minimum age is 21 for gaming and 18 for pari-mutuel racing.

Where a Sports Bet May Lawfully Be Placed in South Dakota

The controlling statute is SDCL 42-7B-79:

"Any sports wagering may only be conducted on the premises of a licensed gaming establishment as approved by the commission within the city of Deadwood. Each operator … shall install and maintain equipment that is approved by the commission to ensure that all bets are placed on the premises of a licensed gaming establishment … within the city of Deadwood."

The authorising provision, SDCL 42-7B-1, permits "wagering on sporting events" along with the other licensed games "within the city limits of the city of Deadwood, South Dakota", and its source line records the 2021 session law that added it. The regulator is the South Dakota Commission on Gaming, a division of the Department of Revenue, whose gaming pages state that "you must be at least 21 years of age for wagering in the casinos in Deadwood and at the tribal casinos".

The Deadwood Limit Is Constitutional

Article III, Section 25 of the South Dakota Constitution first forbids the Legislature to authorise "any game of chance, lottery, or gift enterprise, under any pretense, or for any purpose whatever", then carves out the state lottery, and finally this market:

"Further, it shall be lawful for the Legislature to authorize by law, roulette, keno, craps, wagering on sporting events, limited card games and slot machines within the city limits of Deadwood."

The section's own history line records the amendment that inserted sporting events: "Amendment proposed by SL 2020, ch 1, § 2 approved Nov. 3, 2020." Because the words "within the city limits of Deadwood" are constitutional text, a statewide mobile market cannot be created by ordinary legislation. That is why the live proposals are joint resolutions proposing a further amendment for submission to the voters.

Advance Deposit Sports Wagering Is Not Remote Betting

This is the detail most often reported wrongly. SDCL 42-7B-4(2) defines advance deposit sports wagering as a method by which an eligible individual may "deposit money into an account and use the balance to pay for bets placed on the premises of a licensed gaming establishment … in the city of Deadwood". SDCL 42-7B-78 then requires in-person enrolment:

"A person who opens an account for advance deposit sports wagering … shall establish the account in person at the operator's or route operator's licensed gaming establishment within the city of Deadwood."

So the account exists to fund a wager made inside the building, not to carry one out of it. Two further limits shape the product: SDCL 42-7B-14 caps any bet at one thousand dollars, and SDCL 42-7B-82 bars wagers on high school and minor league events, on an individual athlete's performance in a single collegiate game, and on any collegiate game involving a South Dakota university or college.

Tribal Gaming in South Dakota

Tribal sports wagering rests on compact amendments approved under the federal Indian Gaming Regulatory Act, three of which are sourced in the Federal Register. The amendment for the Sisseton-Wahpeton Oyate, effective 3 December 2021, "authorizes the Tribe to engage in sports wagering at the Tribe's class III gaming facilities". The Oglala Sioux Tribe amendment, effective 14 April 2022, "permits the Tribe to operate sports wagering within the Pine Ridge Reservation". A further amendment for the Crow Creek Sioux Tribe was published on 14 June 2022. Whether a venue currently takes sports wagers, and whether any permits on-premises mobile wagering, is not published by the state and is a question for the tribal gaming authority.

Horse Racing Betting in South Dakota

Pari-mutuel wagering is regulated by the same Commission under SDCL chapter 42-7, and the industry is very small. The Commission's annual report for the 2024 fiscal year records that "one Simulcast Provider operated in South Dakota providing services to one Simulcast Site in North Sioux City" and that "there was live horse racing for 2 days in Fort Pierre, South Dakota on October 7th and 8th 2023". Simulcast wagering is tied to physical locations: SDCL 42-7-58.3 requires that "all approved simulcast races shall be conducted at a licensed location".

On remote racing accounts the position is narrower than the statute books suggest. SDCL 42-7-56(15) gives the Commission power to make rules "for the authorization, regulation, and auditing of account wagering on horse and dog racing" — but that is an enabling power rather than a licensed product. It could not be established from a state source that such rules have been made, and no licensed account wagering provider for South Dakota is published, so none is named here. The best indication of the position is that a bill was filed in 2026 to create exactly such a licence.

What Is Pending in South Dakota

Three measures, and their titles tell a reader what is at stake. 2025 SJR 507 was a joint resolution "proposing and submitting to the voters … an amendment to the Constitution of the State of South Dakota, providing for wagering on sporting events via mobile or electronic platform". 2026 SJR 504 carries the same title. On racing, 2026 HB 1058 would "require licensure for online pari-mutuel wagering pools for horse and dog races, and clarify the application of tax therefor". The action histories of all three could not be retrieved, so nothing is said about their outcomes; what the titles establish is that the legislature itself understands mobile wagering to need a constitutional amendment and a popular vote, and that licensing remote pari-mutuel pools is still a proposal.

Minimum Ages in South Dakota

Two ages apply. For gaming in Deadwood, including sports wagering, SDCL 42-7B-35 provides that "any participant in any gaming shall be twenty-one years or older", and the Department of Revenue says the same for tribal casinos. For pari-mutuel racing the floor is 18: SDCL 42-7-76 refers to collecting contributions "from any person eighteen years or older" toward the entry of a horse or dog in a race.

Prediction Markets in South Dakota

South Dakota is recorded as a grey market, and no state action on sports-event contracts could be located: neither the Commission on Gaming nor the Attorney General has published a verifiable cease-and-desist order, advisory or opinion on prediction markets. South Dakota is named among the states signing the multistate amicus brief of 16 January 2026 in the Ninth Circuit appeal concerning sports wagering offered on tribal lands, which is a statement about sovereign authority rather than a prohibition of anything inside South Dakota.

Responsible Gambling in South Dakota

The state publishes its helpline through the South Dakota Lottery: "Call the Problem Gambling Helpline at 1-888-781-HELP. Your call is always confidential." Dialled in full that is 1-888-781-4357. Treatment funding is statutory — SDCL 42-7B-48.3 provides for treatment and counselling grants from the Gaming Commission fund, and the 2024 annual report records that up to thirty thousand dollars may go to the Department of Social Services for them. Because the lawful market is on-premises, limits and exclusion requests are made to the licensed establishment or the tribal gaming authority.
