Best online sportsbook Connecticut is a shorter list than almost anywhere else in the country, and not by accident. Connecticut caps its legal mobile sports betting market at exactly three operators by statute, so the real question for a bettor here isn't which app to download out of a dozen options — it's which of the only three that will ever exist is worth the download.
A Compact, Not a License Application
Most states run sports betting through an open or semi-open licensing process. Connecticut doesn't. Governor Ned Lamont signed amended tribal gaming compacts with the Mashantucket Pequot and Mohegan tribes in May 2021, and those compacts — not a state gaming commission handing out applications — are what created Connecticut's entire legal sports betting market. Mobile wagering went live October 19, 2021, regulated day to day by the Connecticut Department of Consumer Protection's Gaming Division.
Is Connecticut Sports Betting Legit? FanDuel and DraftKings Are Close
FanDuel held 38.64% of Connecticut's online handle in March 2026, with DraftKings close behind at 37.16% — a gap under a point and a half, thin enough that either app can lead in a given month. FanDuel runs through the Mohegan Tribe's seat, tied to Mohegan Sun in Uncasville. DraftKings runs through the Mashantucket Pequot Tribal Nation's seat, tied to Foxwoods Resort Casino. Neither brand holds a standalone Connecticut license the way it might in a state with open competition — both exist here because a specific tribe chose them as a compact partner.
The Seat That Changed Hands: Fanatics
The third seat belongs to the Connecticut Lottery Corporation, and it has changed operators once already. Rush Street Interactive ran it under the PlaySugarHouse brand from the 2021 launch until exiting the lottery agreement in March 2023. Fanatics Sportsbook took over, becoming the lottery's full, exclusive partner in December 2024 — making Fanatics the newest brand in the state even though the seat itself is as old as the market.
Connecticut's three-operator market at a glance
- FanDuel: 38.64% share (March 2026) — Mohegan Tribe seat
- DraftKings: 37.16% share (March 2026) — Mashantucket Pequot seat
- Fanatics: ~24% share — CT Lottery seat, took over Dec. 2024
- Total legal operators, ever: 3
How Safe Is Connecticut's Model for Bettors?
All three apps answer to the same regulator, and all three trace back to a party with direct accountability to the state — two federally recognized tribes and the state's own lottery corporation. That's a different safety profile than a state that licenses dozens of commercial operators: fewer choices, but each one backed by an entity the state already has a decades-long relationship with. Connecticut taxes both online and retail sports betting at a flat 13.75% of adjusted revenue into the General Fund — a separate, lower rate than the state's 18% online casino tax, which steps up to 20% after the fifth year of iGaming in 2026.
None of this is a way to make money — it's 21+ entertainment with a built-in house edge, available in Connecticut through exactly three state-overseen apps and no others.
The short list
- 1. FanDuel — Narrow handle leader, tied to Mohegan Sun
FanDuel held 38.64% of Connecticut's online sports betting market in March 2026, just ahead of DraftKings' 37.16%, continuing a lead it has held since the state's October 19, 2021 launch. Its Connecticut license runs through the Mohegan Tribe's compact slot, tied to Mohegan Sun in Uncasville rather than a standalone operator license.
- 2. DraftKings — Within 1.5 points of first, licensed through Foxwoods
DraftKings trailed FanDuel by less than a point and a half of market share in March 2026 (37.16% to 38.64%) — close enough that either app leads in a given month. Its license is the Mashantucket Pequot Tribal Nation's compact slot, tied to Foxwoods Resort Casino, the same structural arrangement FanDuel uses with its own tribal partner.
- 3. Fanatics Sportsbook — The lottery's pick, replacing PlaySugarHouse in 2024
Fanatics Sportsbook holds the Connecticut Lottery Corporation's exclusive third license, the one slot in the compact not tied to either tribe. It only became the lottery's full partner in December 2024, after Rush Street Interactive exited the PlaySugarHouse deal in March 2023 — making it the newest of the three brands here despite the slot itself predating the other two launches.
The honest verdict
FanDuel is the top pick for a Connecticut account, holding a narrow lead over DraftKings in monthly online handle through early 2026 (38.64% to 37.16% of the market in March) while operating through its compact partnership with the Mohegan Tribe and Mohegan Sun. DraftKings is close enough behind that the gap functions more like a coin flip than a real edge, running through its own compact partner, the Mashantucket Pequot Tribal Nation and Foxwoods Resort Casino. Fanatics Sportsbook is the honest third option, holding roughly a quarter of the market as the Connecticut Lottery Corporation's exclusive sports betting partner — a seat it only took over in December 2024 after Rush Street Interactive's PlaySugarHouse walked away from the lottery deal in March 2023. There is no fourth app to recommend: Connecticut's compact structure legally caps the field at three, so a reader who sees a brand marketed elsewhere and does not see it here is not missing an option, they are looking at a state that does not offer it. None of this is a way to make money — it's 21+ entertainment regulated by the Connecticut Department of Consumer Protection's Gaming Division, taxed at a flat 13.75% of revenue into the state's General Fund.
Questions this list actually answers
What is the best online sportsbook in Connecticut?
FanDuel, by a narrow margin — it held 38.64% of Connecticut's online handle in March 2026 to DraftKings' 37.16%, a gap thin enough to flip month to month. Fanatics Sportsbook holds the remaining share as the Connecticut Lottery's exclusive third license. All three are the only sportsbook apps Connecticut law allows.
Is online sports betting legal in Connecticut?
Yes. Governor Ned Lamont signed amended tribal gaming compacts with the Mashantucket Pequot and Mohegan tribes in May 2021, and mobile sports betting launched statewide on October 19, 2021. The Connecticut Department of Consumer Protection's Gaming Division regulates the market, and operators must verify a bettor is 21 or older and physically inside Connecticut.
Why are there only three sportsbook apps in Connecticut?
Connecticut's compact structure doesn't create an open licensing process the way most states do. It grants exactly three market-access slots: one to the Mashantucket Pequot Tribal Nation (currently DraftKings), one to the Mohegan Tribe (currently FanDuel), and one to the Connecticut Lottery Corporation (currently Fanatics Sportsbook). A brand can only enter Connecticut by taking over one of those three existing slots when an operator exits — it can't apply for a new one.
What happened to PlaySugarHouse in Connecticut?
PlaySugarHouse was Rush Street Interactive's brand running the Connecticut Lottery's sportsbook slot from the 2021 launch until Rush Street exited that agreement in March 2023. The lottery brought on Fanatics Sportsbook as the replacement, with Fanatics becoming the full, exclusive partner in December 2024. The slot stayed the same; only the operator's name on it changed.
How much does Connecticut tax sports betting?
Connecticut taxes both online and retail sports betting at a flat 13.75% of adjusted gross revenue, with proceeds going to the state's General Fund rather than an earmarked program. That's separate from the state's online casino (iGaming) tax, which sits at 18% and is scheduled to rise to 20% after the fifth year of operation in 2026.
Is Connecticut sports betting safe?
Yes — all three apps hold active licenses tied to the Connecticut Department of Consumer Protection's Gaming Division oversight, and each one's compact partner (Foxwoods, Mohegan Sun, or the CT Lottery) carries direct accountability to the state. Readers looking for a fourth or fifth app marketed in other states should know Connecticut simply doesn't license one — it isn't an oversight to search harder for.
