South Dakota Sports Betting Explainer

The landscape of sports wagering in South Dakota is defined by a unique, geographically restricted retail model, a direct consequence of the state’s legislative history and constitutional limitations. Following a successful voter referendum in 2020, sports betting was legalized, but its operation is strictly confined to the city limits of Deadwood and the premises of tribal casinos across the state. This framework establishes South Dakota as a retail-only market, where the convenience of statewide mobile wagering remains elusive, despite repeated legislative attempts to expand the offering. The market officially launched in September 2021, coinciding with the start of the NFL season, offering in-person betting at licensed establishments.

Note for US readers: Polymarket is now live for real-money trading in the US following its 2025 acquisition of QCX, a CFTC-regulated exchange, available in most states except Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, New Jersey, Nevada and Ohio. New US users can claim a 100% deposit match up to $50 with code ACQUIRE05. Market prices shown are real-money figures from the Polymarket platform. Kalshi, also CFTC-regulated, trades in all 50 states.

The following table provides a snapshot of the current regulatory environment:

Licensed Operators and the Retail Footprint

The South Dakota sports betting market is characterized by its limited access, requiring patrons to be physically present at a licensed facility to place a wager. In Deadwood, the historic gaming town, several casinos have partnered with major national sportsbook brands to offer retail betting.

Key licensed operators and their partners in Deadwood include:

• BetMGM Sportsbook at Tin Lizzie Gaming Resort
• Dale’s Sportsbook at Deadwood Mountain Grand
• Cadillac Jack’s Gaming Resort (offering sports wagering)
• Gold Dust Casino (offering sports wagering)
• BetLodge Sportsbook at Deadwood Lodge

These operations are restricted to the physical premises of the licensed casinos, meaning that while some may utilize a proprietary app, it is only functional within the geofenced boundaries of the establishment. This restriction has led to a market with a relatively low handle and tax revenue compared to states with robust mobile wagering.

The Role of Tribal Gaming

The involvement of tribal nations is a critical component of South Dakota’s gaming ecosystem, extending the availability of retail sports betting beyond Deadwood. Under existing Tribal-State Class III Gaming Compacts, tribal casinos are permitted to offer sports wagering on their sovereign lands. This provision ensures that sports betting is available at various locations across the state, provided it is conducted in-person.

Notable tribal casinos that have launched sports betting operations include:

• Dakota Nation Sportsbook at Dakota Sioux Casino & Hotel (Watertown)
• Rosebud Casino (Rosebud Sioux Tribe)

The tribal compacts are subject to federal approval and allow the tribes to regulate and conduct sports wagering in accordance with their own ordinances, provided they align with the compact’s terms. This dual-market structure—Deadwood and tribal lands—is a defining feature of the state’s regulatory environment.

Alternatives: DFS and Prediction Markets

Given the absence of statewide mobile sports betting, residents often turn to alternative forms of wagering.

Daily Fantasy Sports (DFS)

South Dakota has adopted a permissive stance toward Daily Fantasy Sports (DFS). The state has not passed specific legislation to either legalize or prohibit DFS, creating a regulatory vacuum that allows major operators like DraftKings and FanDuel to operate freely. This de facto legality provides a mobile-accessible alternative for residents to engage in sports-related contests.

Prediction Markets

The legal status of prediction markets like Kalshi and Polymarket is more complex and generally falls outside the scope of South Dakota’s sports betting law. These platforms, which allow users to bet on the outcome of future events (e.g., political elections, economic indicators), are often regulated by the Commodity Futures Trading Commission (CFTC) as designated contract markets. While they operate in a separate regulatory sphere, their availability provides another avenue for residents to engage in event-based wagering.

Legislative Journey and Unique Characteristics

The path to legal sports betting in South Dakota was a two-step process. First, Constitutional Amendment B was approved by voters in November 2020, authorizing the Legislature to allow sports wagering within Deadwood. This was followed by the passage of Senate Bill 44 (SB 44) in 2021, which established the regulatory framework and the 9% tax rate on Adjusted Gross Revenue (AGR).

A key characteristic of the South Dakota market is the prohibition on in-state college sports betting. This restriction, common in many states, prevents wagers on games involving South Dakota colleges or on the performance of individual college athletes, a measure intended to protect the integrity of collegiate sports.

Professional Sports Context

South Dakota is one of the few states without a major professional sports franchise. The state’s sports culture is heavily focused on collegiate athletics and minor league teams.

• Minor League Teams: Rapid City Rush (ECHL – Hockey), Sioux Falls Skyforce (NBA G League – Basketball), Sioux Falls Canaries (American Association – Baseball).
• Fan Allegiance: Due to geographic proximity, residents often align their loyalties with major professional teams in neighboring states, such as the Minnesota Vikings (NFL), Denver Broncos (NFL), and Kansas City Chiefs (NFL).

Future Outlook

The future of sports betting in South Dakota hinges on the expansion of mobile wagering. Legislative efforts to bring online betting to the state have consistently failed, primarily due to constitutional hurdles and opposition from those who favor the current retail-only model. Any future expansion would likely require another constitutional amendment, a lengthy and challenging process.

The current retail model, while limited, has provided a regulated environment for sports wagering, particularly benefiting the historic Deadwood gaming industry and the state’s tribal partners. However, the state’s low tax revenue from sports betting—less than $100,000 in 2023—underscores the financial limitations of a retail-only market in the modern era. Until a constitutional change is enacted, South Dakota will remain a niche market, serving primarily tourists and local patrons willing to visit a physical location to place a bet.

“The retail-only model in South Dakota is a testament to the state’s cautious approach to gaming expansion, prioritizing the preservation of its existing gaming hubs in Deadwood and on tribal lands over the potential revenue gains of a full-scale mobile market.”
