History of Gambling in Missouri

Bingo and Charitable Gaming (1980s)

Like many U.S. states, Missouri’s first step toward regulated gambling came through games of chance for a good cause. During the early 1980s, charitable bingo paved the way for a new era in the Missouri gambling timeline.

In November 1980, Missouri voters considered Amendment 3, known as the Missouri Authorization of Bingo Amendment. The measure allowed nonprofit, religious, fraternal, and veterans organizations to host bingo events and raise funds for community programs. It passed overwhelmingly with 71.5% approval, marking the first legally sanctioned form of gambling in the state.

Over time, Missouri expanded charitable gaming to include pull-tabs and merchandise coin boards. Today, the Charitable Games Division of the Missouri Gaming Commission licenses and regulates these activities, ensuring that proceeds continue to support education and public benefit through the state’s Proceeds for Education Fund.

Missouri Lottery (1986)

Not long after the success of charitable bingo, Missouri took its next major step in the Missouri gambling timeline by creating a state-run lottery.

In November 1984, voters approved Amendment 5 ,
authorizing lawmakers to establish a state lottery. The measure passed with nearly 70% support, and the following year the framework was set through Senate Bill 44.
In January 1986, the first Missouri Lottery tickets went on sale. In 1988, Missouri became a charter member of the Multi-State Lottery Association (MUSL), joining interstate jackpot games.

Horse Racing and Pari-Mutuel Betting (1984–1986)

During the 19th and early 20th centuries, Missouri horse betting was a popular pastime. Historical records mention races dating back to the 1760s, with one of the most famous events—the St. Louis World’s Fair Handicap—held in 1904 and offering a remarkable $50,000 purse.

Pari-mutuel wagering only became officially legal in the 1980s. In 1984, voters approved Amendment 7 with 60% in favor, authorizing betting on live and simulcast races and creating the Missouri Horse Racing Commission to regulate the industry. This marked another milestone in the Missouri gambling timeline, expanding legal wagering beyond charitable games and the lottery.

However, the industry struggled to stay afloat. When riverboat casinos became legal in the 1990s, they quickly drew players away from the racetracks. A 2002 proposal to permit year-round simulcast wagering failed in the General Assembly, effectively ending Missouri’s live horse-racing scene.

Today, Missouri allows pari-mutuel betting in theory, but no active racetracks operate in the state, and off-track betting is unavailable. The sport remains an important historical chapter in the broader history of gambling in Missouri.

The Return of Riverboat Casinos (1990s)

Reprising its history with 19th-century steamboats, Missouri introduced legal riverboat casinos in the 1990s.

In 1989, Iowa was the first state to legalize riverboat gambling. Then, Missouri voters approved a 1992 referendum to authorize gambling on boats on the Mississippi and Missouri rivers. A couple of riverboat casinos opened, although at that time, Missouri gambling laws did not allow slot machines or roulette wheels, but only “skill” games like poker and real money blackjack.

However, the Supreme Court of Missouri subsequently overturned the law resulting from that 1992 vote. That meant another vote and law were necessary to allow Missouri casinos.

The next attempt came in 1994, first in April when a special election took place to vote on the Missouri Riverboat Gambling Amendment. That vote failed by a very slim margin, with 50.08% against and 49.92% in favor. However, another vote on the same amendment in November passed, with nearly 54% approving.

The new law officially allowed games of chance like slot machines and variants of roulette for the first time. It also imposed a $500 “loss limit,” preventing patrons from purchasing more than $500 worth of chips in a two-hour span — a rule that remained in effect until 2008, when voters approved Proposition A, removing the limit and increasing casino taxes.

There was also a requirement that the riverboats actually take short cruises, but several nonetheless remained moored most of the time. Another referendum in 1998 officially removed the cruising requirement, thereby allowing “boats in moats” as long as they were positioned in spaces containing water (even human-made spaces) that were located within 1,000 feet of the main channels of either the Mississippi or Missouri rivers. (At the time of the vote, 10 out of 15 riverboat casinos in the state were already permanently docked.)

Later, in 2008, the state removed the “loss limit” rule, which considerably boosted Missouri gambling revenue. Today, 13 retail locations operate in the state.

Missouri Legalizes Daily Fantasy Sports (2016)

While the state has yet to legalize betting, it has already passed a law explicitly allowing daily fantasy sports contests in Missouri. In fact, Missouri is one of a relatively small number of states with such a law on the books, although many states still allow DFS without having laws authorizing the contests.

The law is the Missouri Fantasy Consumer Protection Act of 2016. It requires DFS providers to apply for licenses and to pay an annual licensing fee. The sites also have to pay the state 11.5% of their net revenue, which goes toward the Gaming Proceeds for Education Fund.

DraftKings, FanDuel, and a half-dozen other daily fantasy sports sites currently have licenses to offer contests to DFS players in Missouri.

Missouri Sports Betting Bills and Legislative Timeline (2018–2024)

PASPA Repeal and Early Proposals (2018–2020)

The history of online sports betting in Missouri — and the long series of Missouri sports betting bills that followed — began shortly after the U.S. Supreme Court repealed the Professional and Amateur Sports Protection Act (PASPA) in 2018. That landmark ruling allowed each state to decide whether to authorize sports wagering within its borders, setting off a wave of legislative efforts nationwide.

In Missouri, lawmakers wasted little time. HB 2320 (Rep. Bart Korman) and SB 767 (Sen. Denny Hoskins) became the state’s first formal sports-betting proposals. Both bills sought to legalize wagering at licensed riverboat casinos and through approved online platforms. Early frameworks mirrored neighboring states’ systems, focusing on low tax rates and casino tethering.

However, from the start, key disagreements slowed progress. Legislators debated whether to require official league data for in-play bets, how to handle wagering on collegiate events, and how many “skins” — individual online brands — each casino could operate.

Meanwhile, another issue began to surface: the spread of unregulated “gray-market” video gambling machines in gas stations and bars. By 2019–2020, these machines had become a flashpoint, with law enforcement and lawmakers calling for clearer definitions of legal versus illegal play. The tension between expanding legal wagering and curbing unlicensed gaming would become a recurring theme in the Missouri gambling timeline for years to come.

Despite growing public support and industry pressure, no consensus emerged before the end of 2020. Still, the groundwork was laid for the next phase in the history of gambling in Missouri — one dominated by political gridlock and competing agendas.

Legislative Deadlocks and Rival Bills (2021–2023)

2021: Early Momentum Meets Division

As part of the ongoing Missouri sports betting timeline, the state entered 2021 with renewed optimism. One House bill (HB 619) and three Senate measures (SB 18, SB 217, and SB 256) signaled serious intent to legalize online wagering. Early consensus formed around low taxes and casino partnerships, but sharp divisions soon emerged over official league data requirements, restrictions on college prop bets, and even a proposed 0.75% royalty fee to professional leagues.

At the same time, lawmakers advanced SB 10, a bill targeting gray-market gaming machines. The effort highlighted how widespread unregulated gambling had become — and how intertwined that issue was with sports-betting reform.

By February, the Senate Appropriations Committee focused on SB 256 and SB 217, with debate centering on three key questions:

• Should each casino be allowed three online “skins,” or only one?
• Must operators purchase official league data for in-play bets?
• Could professional teams host betting kiosks or “stadium districts”?

Casinos supported a flexible approach; teams signaled openness to both sides. But the wildcard remained video lottery terminals (VLTs) which some senators insisted on including in any sports-betting deal.

In March, HB 1364 added new complexity by proposing a comprehensive package including iCasino and online poker, with a 6.75% sports-betting tax and 12% iCasino tax. The sweeping nature of the proposal divided lawmakers further.

Everything came to a head in April when SB 98, combining sports betting and VLTs, reached the Senate floor. A late amendment requiring a statewide referendum passed 17–15, prompting the bill’s withdrawal. With that, hopes for 2021 legalization collapsed. The year closed with Rep. Jim Murphy pre-filing a new iCasino + sports-betting + poker bill for 2022 — signaling that, while the effort had failed, the key debates (VLTs, tax rates, league data) were far from over.

2022: Progress and the Senate Choke Point

In 2022, optimism returned. Lawmakers introduced several key Missouri sports betting bills seeking to modernize the Missouri gambling timeline with a comprehensive, casino-tethered approach allowing multiple skins per property and modest tax rates. Pro teams and casinos aligned behind a House proposal that easily cleared committees.

Yet the Senate again became the choke point. The same fault line that doomed 2021 — VLT inclusion — reappeared. One camp demanded a clean sports-betting bill; another refused to proceed without VLT legalization. Disputes over official data mandates, tax levels, promotional deductions, and in-person registration further slowed progress.

A marathon floor debate ended in a filibuster, consuming the remainder of the session. By sine die in May, betting activities had once again cleared the House but died in the Senate. Meanwhile, Kansas legalized and launched online sports wagering in 2022, siphoning wagering activity from Missouri’s border regions and intensifying political pressure back home.

2023: Familiar Allies, Familiar Roadblocks

The history of online sports betting in Missouri reached a pivotal moment in 2023. Virtually every major stakeholder — from the Kansas City Chiefs and St. Louis Cardinals to DraftKings, FanDuel, and riverboat casinos — backed a streamlined plan through HB 556/HB 581, featuring a 10% tax and up to three skins per casino.

The House passed the bills decisively, 118–35, reflecting bipartisan and public enthusiasm. But the Senate once again derailed the effort. Sen. Denny Hoskins, a longtime VLT advocate, insisted that any sports-betting measure include authorization for video lottery terminals, framing them as a crucial revenue source for veterans’ programs.

Casinos and teams opposed the linkage, arguing it would “poison” the bill. Committee votes mirrored the divide: SB 30 (clean sports betting) advanced easily, while SB 1 (with VLTs) failed. On the floor, a threatened filibuster killed momentum despite a proposed tax increase to 15%.

By session’s end, sports gambling had cleared the House but again stalled in the Senate. The stalemate sparked sharper rhetoric — legislative leaders called the inaction “embarrassing” — and prompted serious discussion of a voter-led ballot initiative. The pattern was set: overwhelming support in the House, consistent blockage in the Senate, and rising frustration among Missouri’s sports community and betting public.

Momentum Builds in 2024

By 2024, patience had evaporated. Six neighboring states — Kansas, Illinois, Iowa, Arkansas, Tennessee, and Kentucky — had already legalized it, and Missourians were driving across borders to wager. Lawmakers faced mounting pressure from constituents, casinos, and professional franchises. These efforts marked one of the most significant turning points in the Missouri sports betting timeline, as multiple sports betting bills converged ahead of the successful 2024 ballot initiative.

Rep. Dan Houx’s HB 2331 led the new push, proposing a 10% tax rate, strict college betting restrictions, and a Compulsive Gamblers Fund. The bill cleared key committees and reached the House floor. GeoComply data revealed over 430,000 blocked Super Bowl wagers, underscoring public demand. Early polls showed more than 60% of Missourians supporting legalization.

In the Senate, Sen. Tony Luetkemeyer’s SB 852 offered a “clean” 12% bill, while Sen. Denny Hoskins’ SB 824 again paired betting with VLTs — a combination many viewed as a guaranteed failure. Hoskins even called himself “an obstructionist until I get my way.” Minority Leader Crystal Quade’s HB 2835 attempted a compromise including both sports wagering and VLTs, but faced fierce opposition from casinos and teams.

As the 2024 legislative session closed without progress, focus shifted outside the Capitol. The Missouri Sports Betting Alliance — a coalition including all six professional franchises (Chiefs, Cardinals, Royals, Blues, SC, and KC Current) along with FanDuel, DraftKings, and other major operators — launched a citizen-led ballot initiative under the PAC Winning for Missouri Education.

The proposal mirrored previous legislative drafts: a 10% tax on gross gaming revenue, with funds dedicated to education and responsible-gaming programs. After collecting over 340,000 valid signatures, the initiative easily surpassed the 170,000 threshold.

Despite lawsuits challenging signature verification, the Secretary of State certified the ballot in August 2024, setting up a November vote. Missouri’s professional sports teams led the campaign for a “yes” vote, spearheaded by Cardinals President Bill DeWitt III and Chiefs President Mark Donovan.

On November 5, 2024, voters narrowly approved Amendment 2, legalizing sports betting for adults aged 21 and over. The measure allowed up to 14 operator licenses, established a 10% tax rate, and earmarked revenues for education and problem-gambling funds.

The outcome marked a turning point in the history of gambling in Missouri — transferring power from the legislature to the people and paving the way for full regulatory rollout in 2025.

Implementation and Launch (2025)

The approval of Amendment 2 set off a whirlwind of regulatory preparation. Early 2025 began with turbulence when Secretary of State Denny Hoskins rejected the Missouri Gaming Commission’s (MGC) proposed emergency rules, claiming they didn’t meet emergency-action standards — delaying an anticipated early-summer launch.

Momentum returned in May 2025, when the MGC officially opened licensing applications for casinos and professional sports teams. Regulators confirmed December 1, 2025, as the constitutional deadline for launch. Public feedback ran through July, shaping final rules implemented on August 30.

By mid-summer, operators raced to meet key deadlines. DraftKings and Circa Sports were among the first approved for “untethered” licenses on August 15, while tethered applications followed from BetMGM, bet365, Caesars, FanDuel, Fanatics, and Penn Entertainment.

The MGC released its final operational schedule:

1. October 22 — license awards finalized
2. November 17 — deposits and account setup allowed
3. December 1, 2025 — full statewide launch

During the same period, bet365, already partnered with the St. Louis Cardinals, officially joined the Sports Betting Alliance, strengthening its policy influence ahead of launch.

Finally, on December 1, 2025, Missouri became the 39th U.S. state to offer legal betting — both online and at retail venues — taxed at 10%, with all proceeds directed to education and responsible-gambling programs.

By the time sportsbooks went live, the history of online sports betting in Missouri had come full circle — from legislative gridlock to a successful statewide rollout, marking the culmination of a seven-year journey.

Questions and Curiosities About Missouri Gambling History

Why Are Casinos on Water in Missouri?

Missouri casinos are often referred to as “riverboat casinos” — but do casinos in Missouri have to be on water? In short, yes. When voters approved casino gaming in 1992, the Missouri Constitution restricted gambling to boats operating on the Mississippi and Missouri Rivers, connecting the modern industry to the state’s 19th-century steamboat heritage.

A later amendment in 1998 allowed casinos to remain permanently docked, provided they were built above or within 1,000 feet of a river channel — even if on man-made water. This creative legal compromise led to the rise of the so-called “boats in moats”, stationary casinos that still honor the riverboat tradition while offering a full modern gaming experience. Today, most Missouri casinos sit near the riverfront, maintaining beautiful views even if they no longer cruise the waters.

One of the Most Famous Duels Started Over a Poker Debt

In 1865, a dispute over an unpaid poker debt between Wild Bill Hickok and Davis Tutt erupted into the Springfield duel, a defining moment in frontier lore. The standoff ended with Tutt’s death and became one of the first recorded quick-draw gunfights of the Old West. More than a sensational incident, it fused Missouri’s frontier history with gambling culture, showing how high-stakes card play could spill beyond the table. The story spread quickly in newspapers and memoirs, turning a local confrontation into a national legend within the evolving narrative of Missouri’s gambling past.

What Were the “Boats in Moats”?

After Missouri legalized riverboat casinos in the 1990s, the law required casinos to operate on water. When voters later allowed properties to stay permanently docked, operators built or used small man-made basins under or around the vessels to satisfy the constitutional requirement. The setup earned the nickname “boats in moats.”

This uniquely Missourian solution preserved the state’s riverboat identity while enabling year-round, stationary operations. It also signaled a practical compromise between history and modern regulation, keeping the letter of the law intact without forcing costly cruises that most patrons didn’t expect—or need—in the era of fully licensed casino floors.

What Was the First Casino to Open in Missouri?

The first legal casino to open in Missouri was the President Casino on the Admiral in 1994, a riverboat docked on the St. Louis riverfront. Housed on a refurbished 1940s passenger ship, it offered table games and slots with panoramic views of the Mississippi. The Admiral became a symbol of Missouri’s new gaming era, bridging the romance of steamboat culture with modern, state-regulated entertainment. Its operation demonstrated the viability of riverfront casinos and set the template for properties that followed, before the Admiral ultimately closed in 2010 as the market evolved and newer, larger venues took center stage.

Before Casinos, Traveling Carnivals Brought the Action

During the 1940s–1950s, local fairs and traveling carnivals often hosted unofficial games of chance—from wheel spins to small “policy” lotteries. Though technically illegal, these pop-up attractions filled the gap between the outlawed era of early gambling and later regulated options like bingo, the lottery, and riverboat casinos. They offered low-stakes thrills, prizes, and community spectacle, keeping gambling in the public imagination.

This informal ecosystem foreshadowed Missouri’s eventual shift to licensed, taxed play, showing how demand persisted—and adapted—long before voters and lawmakers rebuilt a formal framework for legal wagering in the late 20th century.

Did Gambling Shape Missouri’s Early Literature?

Yes. Beyond Mark Twain, 19th-century Missouri writers and journalists used gambling as a metaphor for ambition, risk, and moral testing. Newspapers ran cautionary tales about card sharps and river duels, while dime novels romanticized the riverboat gambler as a daring, well-dressed figure who lived by wit and chance. This literary current echoed into the early 20th century, reinforcing the gambler as a cultural archetype. The result is a distinctive strand of Missouri gambling history where literature and lived experience reflect one another, shaping how audiences remember the state’s frontier past.
