Sports betting in the United States has evolved from a niche interest to a mainstream phenomenon, reshaping the landscape of recreational and professional sports.
This transformation has been propelled by significant legislative shifts, most notably the repeal of the Professional and Amateur Sports Protection Act (PASPA) in 2018, which opened the floodgates for states to legalize and regulate sports betting.
This article delves into the ever-expanding world of US sports betting, presenting an analysis of market size, sports betting industry revenue streams, and the variegated performance across states.
US Sports Betting Revenue & Handle (2023/2022)
Handle Vs. Revenue Vs. Hold
When talking about how much money gambling brings in, the two most common terms are “Handle” and “Revenue,” but the difference might not be immediately obvious.
Handle is the term used to describe the total amount of money used by bettors to place their wagers. Revenue describes the amount of money the gambling establishments make after all winnings are paid out. Basically, you can write it out as Handle – Player Winnings = Revenue.
On the other hand, the Hold is the percentage of the Handle that is kept by the gambling establishment. So if a legal sportsbook brought in $1,000,000 in handle, and kept $50,000 in revenue, that would be a hold of 5%.
Sports Betting Revenue, Total Handle & Comparison by State
To fully understand the scope of sports betting in the US, we need to look at the industry on a state level.
First, we’ll take an eagle-eyed view of the top 10 states in 2023 by revenue, then break down each and every one of the 38 states where sports betting is legalized.
Top 10 USA States by Betting Revenue in 2023
Arizona
Legalization Date | September 2021 |
Total Handle Since Legalization | $13.66 Billion |
2023 Handle | $5,880,489,311.80 |
2023 Gross Revenue: | $489,835,726.20 |
Change from Mean National | +70.4% |
Change from Colorado | +25% |
Change from Nevada | +1.65% |
Sports betting was a smash hit right out of the gate in Arizona, earning over $31 million in revenue in its first month even with only two brick-and-mortar operators and eight online sportsbooks participating.
Since then, revenue growth has been fairly consistent, with players having access to 14 physical locations and 17 online operators as of December 2023.
Arkansas
Legalization Date | July 2019 |
Total Handle Since Legalization | $701,142,375 |
2023 Handle | $404,764,327.45 |
2023 Gross Revenue: | $37,190,265.01 |
Change from Mean | -87.1% |
Change from Louisiana | -89.9% |
Though betting was approved and legalized back in 2019, Arkansas has been slow to embrace this option, with only three physical sports betting locations and no online or mobile options until March of 2022.
Colorado
Legalization Date | May 2020 |
Total Handle Since Legalization | $15,775,272,906 |
2023 Handle | $5,560,232,285.15 |
2023 Gross Revenue: | $391,773,823.59 |
Change from Mean National | +36.3% |
Change from Arizona | –20% |
Change from Kansas | +114.8% |
Change from Wyoming | +2,165.5% |
Voting on whether or not to make sports betting in Colorado legal took place in November of 2019 and the measure very nearly didn’t pass. Votes were split, and PropositionDD was pushed through with a meager 50.8% of the vote.
Since then, Colorado has gone from having only 6 online operators to a robust 25 online and 17 brick-and-mortar bookmakers, generating over $61 million in taxes to date.
Connecticut
Legalization Date | October 2021 |
Total Handle Since Legalization | $3,619,352,854 |
2023 Handle | $1,762,933,823 |
2023 Gross Revenue: | $174,817,802 |
Change from Mean | +39.1% |
Change from Massachusetts | -63.8% |
Change from New York | -89.7% |
Change from Rhode Island | +334.1% |
Bettors took to legalized sports betting in a big way in Connecticut, reaching their first billion dollars in handle within the first nine months.
One thing we found interesting is that Connecticut restricts betting on in-state college teams unless that team is participating in a tournament. However, this is not too unheard of, as many states have special caveats like no single-player wagers, and so on.
Delaware
Legalization Date | June 2018 |
Total Handle Since Legalization | $605,492,659 |
2023 Handle | $65,326,807 |
2023 Gross Revenue: | $14,539,393 |
Change from Mean | -94.9% |
Change from Maryland | -97.2% |
Change from New Jersey | -98.6% |
Change from Pennsylvania | -97.9% |
Sports betting in Delaware is not a new thing — though it’s a lot less restrictive now — as it is one of four states that had limited sports betting grandfathered in under PAPSA.
Even though it was one of the first states to embrace sports betting since PAPSA was lifted, it still only offers three brick-and-mortar bookmakers and has yet to legalize online sports betting apps.
District of Columbia
Legalization Date | May 2019 |
Total Handle Since Legalization | $669,781,869 |
2023 Handle | $169,771,690.27 |
2023 Gross Revenue: | $19,048,156.97 |
Change from Mean | -93.38% |
Change from Maryland | -96.3% |
Change from Virginia | -96.6% |
Though it was legalized in 2019, the first legal Washington DC sports bets were not made until May of 2020 due to hiccups with the DC Lottery’s mobile app launch.
Things have begun to pick up speed, however, as more retail locations open up across the city, including William Hill, BetMGM, and FanDuel, having set up shop in the nation’s capital.
Florida
Legalization Date | December 2023 |
Total Handle Since Legalization | No Data |
2023 Handle | No Data |
2023 Gross Revenue: | No Data |
Change from Mean | No Data |
Due to Florida only legalizing in December of last year, there is no real revenue or data to report. Currently, the only sports betting app available to Floridians is the Hard Rock Bet, though residents of the Sunshine State will likely not have to wait long for more options to become available.
Illinois
Legalization Date | June 2019 |
Total Handle Since Legalization | $30,276,158,867 |
2023 Handle | $11,613,463,222 |
2023 Gross Revenue: | $1,002,257,982 |
Change from Mean | +249.55% |
Change from Indiana | +148.1% |
Change from Iowa | +404.3% |
Change from Kentucky | +1677.5% |
Illinois’ sports betting scene had a tumultuous start by bringing in nearly a million dollars in handle during its first month of operations, only to die completely for two months due to the COVID-19 shutdowns.
Once it got back up and running and suspended its peculiar online betting requirements that demanded bettors register for online betting in person, first — things took off and marked Illinois as one of the top 3 states for sports betting profits in 2023.
Indiana
Legalization Date | September 2019 |
Total Handle Since Legalization | $14,840,378,835 |
2023 Handle | $4,337,817,807.15 |
2023 Gross Revenue: | $404,060,030.50 |
Change from Mean | +40.6% |
Change from Illinois | -59.7% |
Change from Kentucky | +616.6% |
Change from Ohio | -56.8% |
Change from Michigan | -6.9% |
Indiana bettors have plenty of places to wager, with 15 brick-and-mortar operators and nearly as many online and mobile options. The most popular sportsbooks based on the amount of bets placed appear to be DraftKings and FanDuel.
Iowa
Legalization Date | August 2019 |
Total Handle Since Legalization | $7,609,713,003 |
2023 Handle | $2,420,464,385.99 |
2023 Gross Revenue: | $198,797,419.22 |
Change from Mean | -30.83% |
Change from Illinois | -80.2% |
Change from Kansas | +9% |
While far from the largest state in terms of sports betting, Iowa was swift to get everything in place. From when it was legalized to when the first bets started rolling in, they only needed three months, and Iowa launched with both physical and online locations in place.
Kansas
Legalization Date | May 2022 |
Total Handle Since Legalization | $2,840,341,982 |
2023 Handle | $2,121,564,412 |
2023 Gross Revenue: | $182,415,461 |
Change from Mean | -36.52% |
Change from Colorado | -53.5% |
Change from Iowa | -8.2% |
Kansas requires those betting on sports to be physically present in the state — and requires geo-location tracking technology for all mobile apps and websites.
While some states have been hesitant to permit wagering on college sports, especially on local teams, Kansas’ laws specifically make provisions for these kinds of bets… so go Jayhawks!
Kentucky
Legalization Date | September 2023 |
Total Handle Since Legalization | $340,813,121.08 |
2023 Handle | $340,813,121.08 |
2023 Gross Revenue: | $56,382,369.32 |
Change from Mean | -80.35% |
Change from Illinois | -94.4% |
Change from Indiana | -86.1% |
Change from Ohio | -93.98% |
Change from West Virginia | +18.13% |
Kentucky is new to the scene and so there is not a lot of data to work from. The state started by accepting wagers at brick-and-mortar locations at the beginning of September and, within three weeks, was also set up with seven online sportsbooks.
It’s also worth noting that Kentuckians as young as 18 years of age can bet on their favorite sporting events — as opposed to the 21-year cutoff of most US states.
Louisiana
Legalization Date | October 2021 |
Total Handle Since Legalization | $5,275,035,907 |
2023 Handle | $2,905,136,865 |
2023 Gross Revenue: | $366,965,819 |
Change from Mean | +27.69% |
Change from Arkansas | +886.5% |
Change from Mississippi | +616.2% |
Sports betting is approved and legal in 55 of the 64 parishes in Louisiana, with mobile betting becoming available in 2022. However, mobile bets will still not be able to be made in parishes that have banned sports gambling, so players in those areas may have to travel a bit.
Maine
Legalization Date | August 2022 |
Total Handle Since Legalization | $82,091,923.45 |
2023 Handle | $82,091,923.45 |
2023 Gross Revenue: | $9,210,175.63 |
Change from Mean | -96.73% |
Change from Connecticut | -94.7% |
Change from Massachusetts | +98.1% |
Change from New York | -99.5% |
Sports betting was slow to roll out in Maine, even after it was legalized. Even though it was voted in early 2022, Maine bettors were not able to get in on the action until November of 2023, giving us little information to work with so far.
Maryland
Legalization Date | May 2021 |
Total Handle Since Legalization | $5,613,460,397 |
2023 Handle | $4,617,323,132 |
2023 Gross Revenue: | $514,081,189.02 |
Change from Mean | +78.9% |
Change from District of Columbia | +2,598.5% |
Change from Pennsylvania | -25.1% |
Change from Virginia | -8.2% |
Maryland specifically built its legislation with a ‘lens of inclusion’ in mind to make it easier for women and minority-owned sportsbooks to set up shop in-state.
Other interesting facts about the Maryland legislation include licensed betting kiosks available to small businesses and the inclusion of betting options at professional sports venues, casinos, and 1,000+ video lottery terminals.
Massachusetts
Legalization Date | August 2022 |
Total Handle Since Legalization | $4,988,637,586 |
2023 Handle | $4,965,975,601 |
2023 Gross Revenue: | $483,059,490.20 |
Change from Mean | +68.1% |
Change from Connecticut | +176.4% |
Change from Maine | +5143.7% |
Change from New York | -71.5% |
Change from Pennsylvania | -29.7% |
While Massachusetts legalized betting in late summer of 2022, it wasn’t until the end of the following January before it started accepting bets (and not until March for online betting).
But even with a relatively late start, Massachusetts has taken in a ton of revenue, which is great for the state with its 15% tax rate on brick-and-mortar bookmakers and 20% on online sports betting websites.
Michigan
Legalization Date | December 2019 |
Total Handle Since Legalization | $13,721,662,647 |
2023 Handle | $4,810,903,876 |
2023 Gross Revenue: | $434,348,364 |
Change from Mean | +51.13% |
Change from Illinois | -56.6% |
Change from Indiana | +7.5% |
Change from Ohio | -53.6% |
Michigan is another state where its slow adoption of legalized online sports betting created something of a dead zone during the COVID-19 shutdowns. Having just started accepting bets in March of 2020, all activity stopped for April through July as the state’s sole options were shut down.
In August, however, everything picked back up, with Michiganders placing almost $16 million in bets, with revenue jumping up immensely in January of 2021 with the introduction of legal online betting options.
Mississippi
Legalization Date | August 2018 |
Total Handle Since Legalization | $2,483,461,600 |
2023 Handle | $474,275,129.90 |
2023 Gross Revenue: | $51,224,141.03 |
Change from Mean | -82.21% |
Change from Arkansas | +37.7% |
Change from Louisiana | -86.0% |
Mississippi was able to start taking bets almost immediately after PAPSA was overruled due to the state having voted to legalize sports betting in preparation for changes in federal law.
While Mississippi has not legalized online sports betting just yet, it does make up for it by hosting almost 30 brick-and-mortar bookmakers.
Montana
Legalization Date | May 2019 |
Total Handle Since Legalization | $179,163,546 |
2023 Handle | $62,258,820 |
2023 Gross Revenue: | $8,446,611 |
Change from Mean | -96.99% |
Change from South Dakota | +736.3% |
Change from Wyoming | -51.1% |
Montana’s entire sports betting scene is operated by the Montana Lottery and requires players to be on-site at a lottery location to place their wagers — even if using the Sports Bet Montana mobile betting app.
Nebraska
Legalization Date | May 2021 |
Total Handle Since Legalization | No Data |
2023 Handle | No Data |
2023 Gross Revenue: | No Data |
Change from Mean | No Data |
Little information is available in Nebraska, due in large part to just how long it has taken to get things going.
While sports betting was stamped and signed in back in 2021, it wasn’t until June of 2023 that bets were able to be placed, and even that is restricted to only three locations — and no sign of any online sports betting options on the horizon.
Nevada
Legalization Date | 1949 |
Total Handle Since Legalization | $37,722,312,639 |
2023 Handle | $8,261,020,999 |
2023 Gross Revenue: | $481,863,000 |
Change from Mean | +67.64% |
Change from Arizona | -1.63% |
Change from Colorado | +23.0% |
Sports betting has been legal in Nevada since 1949, and remained available even when PAPSA was put in place thanks to Nevada being one of the few states to be grandfathered in.
Today, there are roughly 188 brick-and-mortar sportsbooks and 14 different online sports betting sites available to players — with online and mobile sports betting making up roughly 2/3rds of the handle in the last two years.
New Hampshire
Legalization Date | July 2019 |
Total Handle Since Legalization | $2,710,245,025 |
2023 Handle | $822,107,405 |
2023 Gross Revenue: | $80,041,744 |
Change from Mean | -72.13% |
Change from Maine | +769.1% |
Change from Massachusetts | -83.4% |
Change from Rhode Island | +98.7% |
In an interesting bid for power, DraftKings proposed to give the state of New Hampshire 51% of collected gross gaming revenue in return for being the only sportsbook in town. It was an offer the state could not refuse, and as such, all online and retail sports betting options are run by DraftKings exclusively.
New Jersey
Legalization Date | June 2018 |
Total Handle Since Legalization | $45,687,238,008 |
2023 Handle | $11,972,240,548 |
2023 Gross Revenue: | $1,006,587,566 |
Change from Mean | +250.36% |
Change from Delaware | +6826.8% |
Change from Maryland | +95.8% |
Change from New York | -40.7% |
Change from Pennsylvania | +46.6% |
The state of New Jersey spearheaded the fight to overturn PAPSA, resulting in the legalization of sports betting on the federal level and allowing every state to opt in or stay out of the sportsbook marketplace (and potentially miss out on all that sweet, sweet taxable income).
It’s no surprise that the home of Atlantic City produced 2023’s highest amount of sports betting revenue, even with only 12 retail operators and 18 online sportsbooks available.
New Mexico
Legalization Date | October 2018 |
Total Handle Since Legalization | No Data |
2023 Handle | No Data |
2023 Gross Revenue: | No Data |
Change from Mean | No Data |
New Mexico is a bit of an oddball state. When PAPSA was overturned in 2018, the state itself did not move forward with legalizing sports betting.
However, sports betting is still permitted due to the wording of 1988’s Indian Gaming Regulatory Act which states any or all Class III games (including sports betting) are allowed.
As such, sports betting is permitted at many of the tribal casinos in the state, though revenue data is largely non-existent.
New York
Legalization Date | July 2019 |
Total Handle Since Legalization | $35,848,487,230 |
2023 Handle | $19,196,867,481 |
2023 Gross Revenue: | $1,696,664,242 |
Change from Mean | +489.73% |
Change from Connecticut | +870.3% |
Change from New Jersey | +68.5% |
Change from Pennsylvania | +147.0% |
New York’s pre-emptive move on retail sports betting (an act was passed in 2013 and a proper regulatory framework set up) made it easy for New York to capitalize on the federal-level legalization of sports betting.
Between that and the 51% gross mobile revenue tax on sports betting, New York became the first state to break $1 billion in tax revenue generated — not to mention it being the only state at this point to have broken $2 billion in monthly wagers.
North Carolina
Legalization Date | January 2024 |
Total Handle Since Legalization | No Data |
2023 Handle | No Data |
2023 Gross Revenue: | No Data |
Change from Mean | No Data |
North Carolina has finally passed the bill to legalize sports betting, though there is no data or information available as the first legal wagers were not allowed to be made until March 11th, 2024.
North Dakota

Total Handle Since Legalization | No Data |
2023 Handle | No Data |
2023 Gross Revenue: | No Data |
Change from Mean | No Data |
Similar to New Mexico, North Dakota offers sports betting on the reservation lands of federally recognized tribes. This means that there are no legal online betting sites available in the state, and it does not look like there will be any move to shift this any time soon.
Ohio
Legalization Date | January 2023 |
Total Handle Since Legalization | $7,670,544,772 |
2023 Handle | $7,670,544,772 |
2023 Gross Revenue: | $936,365,302 |
Change from Mean | +225.75 |
Change from Indiana | +131.6% |
Change from Michigan | +36.4% |
Change from Pennsylvania | +115.6% |
Change from West Virginia | +1862.3% |
The Buckeye State legalized sports betting at the beginning of 2023. It made almost $1 billion in revenue that first year, generating over $136 million in tax revenue. The gross revenue was initially taxed at a rate of 10%, but after only a few months, Ohio doubled the tax rate to 20%.
Oregon
Legalization Date | January 2023 |
Total Handle Since Legalization | $1,768,143,892 |
2023 Handle | $635,565,166 |
2023 Gross Revenue: | $75,663,580 |
Change from Mean | -73.7% |
Change from Montana | +795.6% |
Change from Nevada | −84.3% |
While the Oregon Lottery put Scoreboard (its own online sports betting app) together in 2019, DraftKings stepped in and took over as the state’s official sportsbook in January of 2022.
However, if you want to bet on collegiate sports, you will have to visit one of Oregon’s two retail sports betting locations, as they’re banned from the state’s sole online provider.
Pennsylvania
Legalization Date | May 2019 |
Total Handle Since Legalization | $26,574,851,990 |
2023 Handle | $7,682,694,849 |
2023 Gross Revenue: | $686,856,678 |
Change from Mean | +139.04% |
Change from Delaware | +4623.0% |
Change from New Jersey | −31.7% |
Change from New York | −59.5% |
Change from Ohio | −26.6% |
Change from West Virginia | +1339.8% |
Pennsylvania offers one of the nation’s most robust markets in terms of both in-person and online betting options — and it’s not surprising given that PA was preparing to make sports betting legal several months before PAPSA was overturned.
With 19 physical locations and 12 mobile betting sites, as well as a 34% tax rate (plus 2% local tax), Pennsylvania’s sportsbook-friendly residents stand to pour quite a lot into the state’s economy.
Rhode Island
Legalization Date | November 2018 |
Total Handle Since Legalization | $1,929,849,515 |
2023 Handle | $461,553,426 |
2023 Gross Revenue: | $40,277,816 |
Change from Mean | -85.9% |
Change from Connecticut | -77.0% |
Change from Massachusetts | -94.7% |
Change from New Hampshire | -49.7% |
Change from New York | -97.6% |
Rhode Island’s state lottery is the sole regulator and has a monopoly on the sports betting market.
RI bettors can wager in person at one of two casinos, as well as through the lottery-run online platform. One interesting thing that Rhode Island does is supply support, technology, and machines for the brick-and-mortar bookmakers in exchange for 51% of the gross gaming revenue.
South Dakota
Legalization Date | September 2021 |
Total Handle Since Legalization | $18,879,008 |
2023 Handle | $9,088,690 |
2023 Gross Revenue: | $1,009,930 |
Change from Mean | -99.56% |
Change from Iowa | −99.5% |
Change from Montana | −88.0% |
Change from Wyoming | −94.2% |
South Dakota has fairly limited options for sports betting, and when it was legalized, it was only voted in on a retail-only basis for casinos in Deadwood, SD. Bettors can place their bets through a mobile app, but only on the casino grounds.
Tennessee
Legalization Date | June 2020 |
Total Handle Since Legalization | $11,185,703,664 |
2023 Handle | $4,295,669,943 |
2023 Gross Revenue: | No Data |
Change from Mean | No Data |
Tennessee only offers mobile and online sportsbooks to its residents, opting out of any physical operators.
Unfortunately for fans of sports betting statistics, starting in July of 2023, the state no longer reports its sports gambling revenue — likely a byproduct of being the only state to calculate its tax revenue as a percentage of the sports handle rather than the gross revenue.
Virginia
Legalization Date | April 2020 |
Total Handle Since Legalization | $13,724,595,466 |
2023 Handle | $5,590,022,862 |
2023 Gross Revenue: | $560,201,501 |
Change from Mean | +94.91% |
Change from Maryland | +8.97% |
Change from West Virginia | +1074.0% |
Virginia legalized sports betting in April of 2020 but didn’t wind up launching a proper retail sportsbook until July of 2022, instead relying on online sports betting options.
Being late to the game in terms of brick-and-mortar options didn’t hurt the great state of Virginia, as it’s in 2023’s top 10 states when sorted by revenue.
Washington

Total Handle Since Legalization | No Data |
2023 Handle | No Data |

Washington state has some pretty restrictive limitations that seem to cause a lot of bettors to flock to offshore betting sites — hurdles like having to use mobile apps on-site, in-person registration, and restricted betting on local college teams seem a bit too tall for some sports fans to get over.
In addition to that, finding accurate handle and revenue data has been very difficult.
West Virginia
Legalization Date | August 2018 |
Total Handle Since Legalization | $2,278,309,140 |
2023 Handle | $483,227,416.29 |
2023 Gross Revenue: | $47,723,640.39 |
Change from Mean | -83.45% |
Change from Ohio | −94.9% |
Change from Maryland | −90.7% |
Change from Pennsylvania | −93.1% |
Change from Virginia | −91.5% |
West Virginia has a nice blend of online and brick-and-mortar operators on tap, and all of them are subject to a business-friendly 10% tax rate.
While it’s far from the top of the list in terms of revenue, West Virginia was another in a handful of states that got all of their legislative ducks in a row before the 2018 PAPSA ruling, so their bookmakers were ready soon after the federal restrictions were lifted.
Wisconsin
Legalization Date | November 2021 |
Total Handle Since Legalization | No Data |
2023 Handle | No Data |
2023 Gross Revenue: | No Data |
Change from Mean | No Data |
Revenue data for Wisconsin is almost non-existent due to all of the legal sports betting options being handled by tribal operators. At this time, physical locations are limited, and there are no real plans to open up online betting options.
Wyoming
Legalization Date | April 2021 |
Total Handle Since Legalization | $357,117,581 |
2023 Handle | $172,247,303 |
2023 Gross Revenue: | $17,293,649 |
Change from Mean | -93.94% |
Change from Colorado | −95.6% |
Change from Montana | +104.7% |
Change from South Dakota | +1611.3% |
While there are physical casinos on tribal lands in Wyoming, none of them are involved in the state’s sports betting industry revenue. Instead, all sports wagers are handled online through the state’s four betting apps: DraftKings, BetMGM, FanDuel, and Caesars.
US Sports Betting Revenue – FAQs

Which US States Have the Most Sports Bettors?
While it is difficult to say how many individual bettors there are in each state, we can guess based on how much was wagered per capita.
New Jersey leads the pack with the largest handle per capita ($11.9 billion wagered with a population of 9.2 million), followed by the state of New York($19.2 billion with a population of 19.84 million).
What is the Biggest Sport for Gambling?
The NFL is far and away the most popular sport to bet on in the United States, with data suggesting that 81% of bettors aged 18 or older have placed a wager on an NFL game.
After that is the NBA with 54%, followed by MLB with 44%, college football with 34%, soccer with 28%, NHL with 26%, and MMA, Boxing, and the UFC with a combined 26%.
Conclusion – What Does the Future of US Sports Betting Look Like?
Since the Supreme Court struck down the Professional and Amateur Sports Protection Act in 2018, almost 40 states have legalized sports betting, which has helped the popularity of this pastime spread immensely — and generated a significant amount of tax revenue.
With over $119 billion wagered by US players alone, which is expected to climb significantly as more states embrace legalized sports betting and online bookmakers, there is little doubt in our mind that, for good or ill, the industry is here to stay and grow even more in the following years.
