Is Sports Betting Legal in Delaware? Yes, With Exactly One App (2026)

Yes. Delaware has legal sports betting statewide, online and in person, and it has had legal sports betting in some form longer than anywhere except Nevada. You can bet from your phone anywhere in the state, at three casinos, and now at self-service kiosks in 89 lottery retailers.

There is exactly one app. Every other guide calls that a monopoly and moves on. The interesting part is why it exists, because the answer is not the one everybody prints.

Quick facts

There is one app because there is no licence to apply for

Search Delaware’s lottery law for the words you would expect to find behind a one-app market and they are not there. “Sole vendor,” “single vendor,” “primary vendor” and “request for proposal” each appear zero times in all of chapter 48. There is no exclusivity clause.

That absence sent our own research down the wrong road. If no statute commands one operator, the reasoning went, then the single app is just a contract, and a second one could show up whenever the state re-bids. That is wrong, and the real answer is more interesting.

What is also missing from Delaware’s code is an internet sports lottery operator licence. Section 4826 authorizes the Lottery Director to operate an internet lottery. It creates no licence, no application, and no class of business that could hold one. The only entity the code licenses to conduct internet lottery games is a “video lottery agent,” and the definition of that term requires holding a horse racing or harness racing meet licence. In Delaware, to run a casino sportsbook you must first be a racetrack.

So the chain has three links, not one: the legislature delegated the power to run the game, the Lottery Office decided to run it online, and then it ran one procurement. In January 2023 it put its internet wagering platform out to bid, seeking what a House resolution describes as “a single, primary vendor.” Rush Street Interactive won it and delivers the product as BetRivers.

What that means in practice is worth stating precisely, because it is the whole page:

• Re-bidding the platform, or awarding it to a different company, needs no legislation. That is a procurement.
• A second, competing sportsbook needs a bill, because somebody would first have to invent the licence for it to hold.

Somebody tried. House Bill 365, introduced April 11, 2024, would have created a new section 4826A and a new power to license internet sports lottery operators. The General Assembly’s own synopsis calls it enabling legislation for a competitive mobile market. It died in House Appropriations on May 23, 2024. And it had already written the incumbent out of its own reach: Section 7 of the bill exempted whichever vendor held the January 2023 contract, “or any renewal or successor contract thereto.”

You will see 2028 cited as the date Delaware’s market opens up. It is not. The state’s audited financial report commits the Lottery to a 20 percent vendor fee “thru August 16, 2028,” but that is the end of a five-year initial term that the same House resolution describes as extendable by five one-year options, which runs to roughly 2033. More importantly, no contract date governs this at all. The structure is not created by the contract, so the legislature can change it in any session, and it already tried four years before the supposed unlock.

The college rule is in the definition, so no regulator can lift it

Delaware does not ban betting on the Blue Hens. It defines them out of the product.

The statutory definition of “sports lottery” in 29 Del. C. § 4803(x) covers any professional or collegiate sporting event “held within or without the State,” and then excludes “collegiate sporting events that involve a Delaware college or university and amateur or professional sporting events that involve a Delaware team.”

Read what that does. A University of Delaware game is not a restricted market inside the sports lottery. It is not the sports lottery. No rulemaking can put it on the board, because the Director’s authority runs to sports lottery events and a Delaware school’s game does not qualify as one. Only the General Assembly can change it, and the only serious attempt was HB 365, which would have struck the exclusion outright and died in committee.

Two details nearly everyone gets wrong:

1. The trigger is the school, not the venue. The definition makes events eligible whether they are held inside or outside Delaware, so a Blue Hens road game in another state is still excluded. Do not import New Jersey’s rule here: New Jersey bans any college game played in New Jersey, and Delaware has no equivalent.
2. It is not just colleges. The second half of the exclusion reaches “amateur or professional sporting events that involve a Delaware team,” and “Delaware team” is defined nowhere in the statute. Delaware has no major professional franchise, so the plain words would reach outfits like the Wilmington Blue Rocks or the Delaware Blue Coats. The state has published no interpretation, so treat that as unresolved rather than settled.

Note also what Delaware does not restrict. The words “proposition” and “player prop” appear zero times in chapter 48 and zero times in the sports lottery regulations. Delaware removes whole Delaware-school and Delaware-team events from the product and leaves prop betting on every other game untouched.

That puts Delaware at one end of a ladder this site has been climbing all year. Maryland’s college prop ban is an approved-events catalog a regulator publishes and can revise. Indiana’s is an executive director’s directive that says of itself that it is subject to change. Washington’s lives in tribal compacts. Montana restricts nothing and has no instrument to repeal. Delaware’s is in the statute.

And here is the twist, in the same body of regulation. What you may bet on is fixed by a statute nobody at the Lottery can touch. What kind of bet you may place is not: the regulations delegate that to a document on the Lottery’s own website, by name, “which may be updated from time to time.” In Delaware the eligible-events rule takes an act of the legislature, and the bet-type rule takes an afternoon.

What a bettor actually does

You must be 21. That sits in two separate statutes, and an underage wager is void with no payout and no refund of the stake. Delaware is not one of the five jurisdictions that still allow betting at 18.

Registration is fully remote. There is no in-person step of any kind before your first wager, which is the opposite of Nevada, where you must show a photo ID to a book employee before your first bet even though mobile betting is statewide.

You must be in Delaware, not from Delaware. The regulations require reasonable assurance that the player is physically located in the state. Residency is irrelevant; presence is not.

The one counter you do have to appear at is the one that shuts you off. Self-exclusion applications must be filed in person at the Lottery office in Dover, and the Lottery says plainly that forms “cannot be requested by phone and mailed.” The regulation is why: an employee has to examine your identification, photograph you, and sign that the photograph and physical description agree with your actual appearance. Coming off the list works the same way in reverse.

One thing to get right, because the harmful version is the intuitive one: the terms are one year, five years or lifetime, and a shorter term is a minimum, not an expiry. Nothing lapses on its own. Your name stays on the list until you go back to Dover in person with government photo ID. A lifetime exclusion cannot be undone at all.

Set beside its neighbours on this site, the shape is clean. Nevada makes you appear once and then lets you bet from anywhere in the state. Montana never makes you appear and never lets you leave the bar. Delaware never makes you appear to bet, and makes you appear to stop.

Delaware does not tax sports betting, because there is nothing to tax

There is no sports betting tax rate in Delaware. There is no sports betting operator to levy one on. The Lottery owns the game, the casinos and stores are its agents, and 29 Del. C. § 4815(c) divides the money. Anyone quoting Delaware a “50 percent tax” is describing a revenue split.

At the three casinos the state takes 50 percent of what the book keeps, and horse racing purses take another slice, at 9.6 percent if the track races thoroughbreds and 10.2 percent if it races standardbreds. Delaware Park is the thoroughbred licensee, so a bet placed there pays 9.6 percent. The same bet at Bally’s Dover or Harrington pays 10.2 percent. The Lottery’s own monthly report reproduces both rates to four decimal places.

Fifty percent is only the casino channel, and it understates what the state keeps. Bets taken at the 89 lottery retailers run on a different subsection with no 50 percent cap at all. Purses are still paid, but they are routed back to the three racetracks, so a parlay card sold in a Wilmington liquor store helps fund purses at tracks the buyer may never visit. By our calculation from the Lottery’s own totals, the state kept about 90 percent of that retail channel and 58 percent of all sports lottery net proceeds in the year to June 2026.

Delaware also breaks a pattern this site keeps running into. Where the regulators in Tennessee, Nebraska, Nevada and Washington publish no handle total at all, the Delaware Lottery publishes handle monthly, by venue, going back to 2009. Sports sales were $252.5 million in the year to June 2026 and $234.8 million the year before.

That long series also tells a story the state has never had to explain. Delaware’s first full year of single-game betting, to June 2019, produced $158.6 million. Then it fell for four straight years to $71.8 million, a decline of about 55 percent, and did not pass its 2019 peak again until its own first full year of mobile betting. Over the same period, every neighbouring state opened a competitive mobile market. We cannot show you causation and no official has claimed it, but the shape is hard to miss.

One honest gap: nobody publishes Delaware’s online-versus-retail split. The Lottery’s sports report has no online column and its iGaming report does not contain the word “sports.” Online wagers sit inside the three casino columns. Any “Delaware online handle” figure you see anywhere is somebody’s estimate.

The history: two limits, and only Congress could lift them

Delaware ran a state football lottery in 1976 called Scoreboard. It was parlay-only and NFL-only, and when PASPA froze sports betting nationally in 1992, that is what Delaware’s exemption preserved. (The statute itself names no state anywhere in its text; the four-jurisdiction list everybody repeats is shorthand.)

In 2009 Delaware tried to expand to single-game betting across multiple sports. The leagues sued, and in OFC Comm Baseball v. Markell, 579 F.3d 293 (3d Cir. Aug. 31, 2009), a unanimous panel held that two separate elements exceeded the exemption. These are two holdings resting on two different premises, and almost every summary chains them into one:

• Because the 1976 scheme involved only NFL teams, wagering on any other sport would violate PASPA.
• Because no single-game betting was ever conducted by Delaware in the qualifying window, single-game betting fell outside the exemption too.

What Delaware was left with, in the court’s own words, was multi-game parlay betting on at least three NFL games. The opinion landed one day before the state’s new scheme was to launch.

That limit is worth pausing on, because of what kind of instrument it was. It was a federal statute as construed by a federal appeals court. The Lottery could not change it. The Governor could not change it. The General Assembly could not change it. Only Congress or the Supreme Court could, and in May 2018 the Supreme Court did.

Delaware then needed no new legislation at all. The Department of Finance, in consultation with the Attorney General’s office, determined there were no legal obstacles, and full single-game betting opened at the three casinos on June 5, 2018, twenty-two days after the ruling, because the 2009 Act had authorized everything already and only PASPA had been in the way.

Delaware was also an early mover online in general: it authorized internet casino and poker games in 2012 and launched in October 2013.

Prediction markets: Delaware argued against Kalshi, then lost, then did nothing

Delaware is in the Third Circuit, the only federal appeals court that has actually ruled on whether state gambling law still applies to prediction markets. On April 6, 2026 it ruled for Kalshi.

The connection nobody else makes is that Delaware helped argue the losing side of that exact case. Attorney General Kathleen Jennings signed the multistate brief supporting the New Jersey officials on June 17, 2025. Ten months later, that case produced the ruling that now binds Delaware’s own federal court.

Two precisions matter here, and this site has been sharpening both:

• The ruling is binding precedent in the federal district courts of New Jersey, Pennsylvania and Delaware. It is not a rule binding Delaware’s state courts, which on a federal preemption question answer only to the Supreme Court. And it came at the preliminary-injunction stage, on a standard asking only whether Kalshi had a reasonable chance of winning.
• It is still the only circuit-level ruling that exists. The Fourth, Sixth and Ninth Circuits have all heard argument and none has decided. Despite what you will read elsewhere, the appeals courts are not yet split.

Since then, Delaware has done nothing of its own. No cease-and-desist, no lawsuit, no attorney general opinion and no Lottery or gaming-enforcement advisory has been made public, and Delaware is not among the nine states the federal government has sued. Jennings has joined at least seven multistate briefs, including in both of the Sixth Circuit cases argued in July 2026, but Delaware has never filed one of its own. It is the pattern we found in Nebraska and Mississippi: joins, but never files.

What makes Delaware’s version sharper is the exposure. In a licensing state, prediction markets compete with the state’s licensees. In Delaware they compete with the state’s own book, and therefore with the State Lottery Fund, the casinos’ commissions and the horsemen’s purses. Delaware has the most direct financial stake of any state, sits inside the one circuit that has ruled against the states, and has taken no action at all.

So what can you actually do in Delaware?

Bet from your phone anywhere in the state at 21, on one app, on any sport, including college games and college player props, as long as no Delaware school and no Delaware team is playing. Bet in person at three racetrack casinos. Buy parlay cards and now use self-service kiosks at 89 stores around the state, where the odds come from a different company than the one that runs the app.

And know that the reason your choice of app is one rather than twelve is not a monopoly contract with an expiry date. It is a licence that has never existed, which means the thing to watch is not a procurement in 2028. It is a bill.
