South Dakota sports betting is legal only in person, at Deadwood casinos and tribal casinos, after voters approved it in 2020. There are no legal statewide betting apps: a 2026 attempt to put mobile wagering on the ballot, SJR 504, passed the Senate and died in a House committee. Here's the law, the age, the federal background and the tax rules.
Sports betting is legal in South Dakota only at Deadwood and tribal casino sportsbooks, approved by voters in 2020; the betting age is 21.
No legal mobile or online sportsbook operates in the state; SJR 504 passed the Senate 23-10 and died 11-2 in a House committee, so it isn't on the November 2026 ballot.
Offshore sportsbook apps aren't licensed by South Dakota or any US state, and federal law treats interstate sports wagering by operators strictly.
Sports wins of $2,000 or more that are at least 300 times the stake are reportable on a W-2G for 2026.

Is sports betting legal in South Dakota?
Yes, but only in person. South Dakota voters approved sports wagering in 2020, limited to Deadwood casinos and tribal casinos, and the state's casino age of 21 applies. Gaming in the state is overseen by the South Dakota Commission on Gaming (opens in a new tab), part of the Department of Revenue.
There's no legal way to bet on sports from a phone anywhere in the state. Residents of Sioux Falls, Rapid City and Aberdeen who want a legal wager have to travel to a casino sportsbook. Our South Dakota online casinos hub covers the rest of the state's gambling law.

Where you can bet: Deadwood and tribal casino sportsbooks
Deadwood is the state's commercial casino town, and its casinos may take sports wagers on site. Tribal casinos can also offer sports betting, under tribal gaming law and their compacts with the state. The Indian Gaming Regulatory Act puts this kind of casino gaming in class III, which requires a tribal-state compact.
We don't list individual sportsbooks or their launch dates, because no reliable source for them was found. Call the casino before you travel to confirm its betting hours and markets. The tribal gaming explainer gives more background on how compacts work.
SJR 504: South Dakota's 2026 push for mobile sports betting
Voters set the 2020 limits, so lawmakers looked to voters again for any expansion to phones. SJR 504, tracked by third-party sources as a proposed statewide electronic sports betting amendment, was the 2026 vehicle for that question.

Why there are no legal South Dakota sports betting apps
Until mobile wagering is approved, no operator can be licensed to take bets on phones statewide. Sportsbook apps licensed elsewhere hold licenses from those states, not from South Dakota, and each state sets its own rules on who may bet and from where.
Federal law reinforces the line. The Wire Act bars people in the business of betting from using wire communications for interstate sports wagers, with an exemption only where betting is legal at both ends. In January 2021 the First Circuit, in New Hampshire Lottery Commission v. Rosen (opens in a new tab), held the Act's prohibitions apply only to sports-related wagers. Our Wire Act page covers the details.
Federal law behind South Dakota sports betting
States can legalize sports betting because of a 2018 Supreme Court decision. In Murphy v. NCAA (opens in a new tab), decided May 14, 2018, the Court struck down the federal law that had stopped states from authorizing sports gambling. South Dakota's 2020 vote followed. See PASPA and Murphy v NCAA.

Offshore sportsbooks and South Dakota bettors
Offshore sportsbooks advertise to South Dakota bettors, but none is licensed by the state or any US state. That means no Commission on Gaming oversight, no state complaint route, and payouts and voided bets on the operator's terms. State law decides the player's position, so read what South Dakota allows before using any site.
Prediction markets and daily fantasy in South Dakota
Prediction-market sports contracts are a live federal fight. A Congressional Research Service report dated August 17, 2026 lists several bills, including the Prediction Markets Are Gambling Act and the Fair Markets and Sports Integrity Act, that would keep sports contracts off federally regulated exchanges; none had been enacted. The CRS report on prediction markets legislation (opens in a new tab) lists them all.

Taxes on South Dakota sports betting wins
Sports winnings are taxable federal income. Under the IRS W-2G instructions (opens in a new tab), a payer reports a sports win for 2026 when it reaches $2,000 and is at least 300 times the wager, and withholds 24% where winnings minus the wager exceed $5,000.
Here's the arithmetic: a $10 parlay paying $3,500 is 350 times the stake and above $2,000, so it's reportable, and winnings minus the wager are $3,490, below the $5,000 withholding line. From the 2026 tax year, the loss deduction is reportedly limited to 90% of losses, up to gains; check IRS guidance. See our gambling taxes page.

Casino offers shown to South Dakota readers (not sportsbooks)
No partner fits this topic, because none of our seven partners is a sportsbook. The two offers below are online casino bonuses for slots, not sports betting offers. Both casinos are offshore and not licensed by South Dakota or any US state, and real-money online casinos are not authorized in the state. The Michigan Gaming Control Board named both in an April 9, 2025 cease-and-desist release. Check your state's law first. We earn a commission on these links and rank partners commercially.
Silver Oak: $2,500 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply).

See the Silver Oak review.
Planet 7: $2,750 Welcome Bonus + 45 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Its own site couldn't be read; third-party reviews report 30x (bonus plus deposit) wagering on slots, a $1,000 max cashout and a $30 card minimum. See the Planet 7 review.

Frequently asked questions
Is online sports betting legal in South Dakota?
No, online and mobile sports betting is not legal in South Dakota. Voters approved sports betting in 2020 only for Deadwood casinos and tribal casinos, in person. SJR 504, which would have asked voters to allow statewide electronic betting, died in a House committee in 2026, so it isn't on the November 2026 ballot. For the full legal picture, see South Dakota gambling laws.
When did sports betting launch in South Dakota?
South Dakota voters approved sports wagering in 2020, limited to Deadwood and tribal casinos. An exact first-bet date wasn't found in the sources used here, so we don't give one. What's clear is that betting remains retail only, and the 2026 push to add mobile wagering failed. The sports betting laws page compares how other states rolled out.
What is the sports betting age in South Dakota?
The minimum age for sports betting in South Dakota is 21, the same as the state's casino age, at Deadwood and tribal casino sportsbooks. Simulcast horse racing has a lower age of 18 according to the state's gaming information. Offshore sites set their own ages and aren't licensed by the state. Our gambling age by state table compares other states.
What happened to SJR 504?
SJR 504 passed the South Dakota Senate 23-10 on February 11, 2026 and then failed 11-2 in a House committee. It would have asked voters to allow statewide electronic sports betting beyond the in-person limits approved in 2020. It won't appear on the November 2026 ballot, and any new attempt would start in a future session. The South Dakota online casinos hub follows any change.
Can I use DraftKings or FanDuel in South Dakota?
Not legally from inside South Dakota, because no mobile sportsbook is licensed in the state. Apps licensed in other states hold those states' licenses, and each state sets its own rules on age and where a bettor must be. If you travel, check that state's requirements first and the app's own terms. Our answer on whether sports betting is legal in your state gives a quick overview.
Are offshore sportsbooks legal in South Dakota?
No South Dakota law authorizes offshore sportsbooks, and none holds a US state license. Federal law, including the Wire Act, targets betting businesses rather than individual bettors, but state law decides the player's position. Practically, an offshore book offers no state complaint route and no protection of your balance. Read our guide to offshore casino legality before you consider one.
Do I pay taxes on sports betting winnings in South Dakota?
Yes, sports betting winnings are taxable federal income. For 2026, a payer reports a win of $2,000 or more that is at least 300 times the stake on Form W-2G, and withholds 24% when winnings minus the wager exceed $5,000. Keep records of tickets, wins and losses. From 2026 the loss deduction is reportedly capped at 90% of losses. See our W-2G form page.
Is daily fantasy legal in South Dakota?
The status of paid daily fantasy sports in South Dakota wasn't found in the sources used for this guide, so we can't give a firm answer. Check the contest operator's own terms for excluded states and the Commission on Gaming for any statement. Daily fantasy is treated differently from sports betting in many states. Our daily fantasy sports laws page explains the national patchwork.
Can I bet on sports online in Sioux Falls?
No, there's no legal online or mobile sports betting anywhere in South Dakota, including Sioux Falls, the state's largest city. Legal wagers must be placed in person at a Deadwood casino or a tribal casino sportsbook, and the minimum age is 21. Third-party coverage describes frustration in Sioux Falls after SJR 504, the 2026 attempt to allow statewide electronic betting, stalled in a House committee. Offshore sportsbook apps that load in Sioux Falls aren't licensed by South Dakota or any US state. Our South Dakota gambling laws page explains the framework, and is sports betting legal in my state compares states.
Do tribal casinos in South Dakota have sportsbooks?
Tribal casinos can offer in-person sports betting in South Dakota under the 2020 voter approval, tribal gaming law and their compacts with the state. Sports wagering counts as Class III gaming under the federal Indian Gaming Regulatory Act, which requires an approved tribal ordinance and a tribal-state compact. We don't list individual tribal sportsbooks or their launch dates, because no reliable source for them was found, so call a casino before you travel to confirm its hours and markets. The age is 21. Our native American casinos guide and Indian Gaming Regulatory Act page explain how compacts work.
What would it take to legalize mobile sports betting in South Dakota?
Because voters set the 2020 in-person limits, expanding betting to phones has gone back through a proposed constitutional amendment. In 2026, SJR 504 would have asked voters to allow statewide electronic sports betting; it passed the Senate 23-10 on February 11, 2026, then failed 11-2 in a House committee, so it isn't on the November 2026 ballot. A new attempt would need to clear both chambers in a future session and then win at the ballot. Licensing rules for operators would follow. Our sports betting laws page and South Dakota online casinos hub track any change.
Would the SAFE Bet Act affect South Dakota sports betting?
Not today, though it could if it ever passed, because it would add federal standards for sports betting in states that have legalized it, as South Dakota has for retail books. The bill was introduced in Congress in 2025, and our sources don't record it as enacted, so it has no effect today. South Dakota's betting rules still come from the 2020 voter approval and the Commission on Gaming, within the room the Supreme Court opened in Murphy v. NCAA in 2018. Check congress.gov for the bill's current status. Our PASPA and Murphy v. NCAA page and prediction markets page cover the federal picture.
Are sports prediction markets legal in South Dakota?
South Dakota's position on sports event contracts wasn't found in our sources, so we can't give a state answer. Federally, a Congressional Research Service report dated August 17, 2026 lists several bills, including the Prediction Markets Are Gambling Act and the Fair Markets and Sports Integrity Act, that would keep sports contracts off federally regulated exchanges; none had been enacted. Until that debate settles, treat these products as unresolved and separate from the state's licensed retail sportsbooks. Our prediction markets page follows the fight, and the daily fantasy guide explains how fantasy contests differ.
Do Silver Oak or Planet 7 take sports bets from South Dakota?
No, neither is a sportsbook; both are offshore online casinos, and none of our seven partners shows a sports betting product in its published materials. Silver Oak's own package is a $10,000 welcome over ten deposits, with 30x or 40x slot wagering depending on the page, and Planet 7's terms come from third-party reviews reporting 30x and a $1,000 max cashout. The Michigan Gaming Control Board named both in an April 9, 2025 cease-and-desist release. Neither is licensed by any US state. You must be 21+, and terms apply. See is Silver Oak legit and is Planet 7 legit.
Can I bet on horse racing in South Dakota?
Yes, simulcast horse racing is legal in South Dakota, and the Commission on Gaming sets its minimum age at 18, lower than the 21 for casino games and sports bets. Simulcast wagering is one of the areas covered on the Commission's gaming pages, alongside Deadwood licensing and sports wagering at licensed venues. Specific venues and online racing options weren't covered by our sources, so check with the Commission before you rely on any app. Parimutuel winnings are taxable federal income, with W-2G reporting at $2,000 and 300 times the wager for 2026. Our gambling age by state table and W-2G form page explain more.
