It was the kind of election night that makes political consultants age a decade in four hours. Honestly, looking at the Amendment 2 Missouri results from November 2024, you'd think the state was split exactly down the middle with a surgical laser.
The measure passed. But barely.
We are talking about a margin of just 0.1%. When the Missouri Board of State Canvassers finally certified the thing in early December, the "Yes" side had cleared the hurdle by only 2,961 votes. In a state where nearly 3 million people showed up to the polls, that is essentially a rounding error. But in the world of constitutional law, a win is a win, even if it’s by the skin of your teeth.
The Final Numbers and That Nail-Biter Finish
If you were watching the returns on election night, it felt like a seesaw. One minute the "No" votes from rural counties would surge, and the next, a dump of data from St. Louis or Kansas City would swing it back.
Here is how the certified count actually shook out:

- Yes: 1,478,652 (50.05%)
- No: 1,475,691 (49.95%)
Because that margin was under 0.5%, the opposition technically had the right to demand a recount. People waited with bated breath to see if the group "Missourians Against the Deceptive Online Gambling Amendment" would pull the trigger. They didn't. They basically said the math was what it was and decided not to fight the certification.
Why Was It So Close?
You’d think sports betting would be a slam dunk in a state that lives and breathes Chiefs football and Cardinals baseball. But the campaign got messy. Fast.
On one side, you had the "Winning for Missouri Education" crew. They spent over $40 million—a record for a Missouri ballot initiative. Most of that cash came from the big dogs: DraftKings and FanDuel. They also had the backing of every major pro team in the state, from the Blues to the KC Current. Their pitch was simple: we’re already betting on our phones, so why let the tax money go to Kansas or Illinois?
On the other side, the opposition was largely funded by Caesars Entertainment. Now, this is where it gets interesting. Caesars isn't against gambling—they own casinos in Missouri. They just didn't like the way this specific amendment was written. They argued it didn't guarantee enough money for schools because of how "promotional deductions" work. Basically, they claimed the sportsbooks could write off so many "free bets" that the actual tax revenue would be peanuts.

Where Does the Money Go?
Now that the dust has settled, we're looking at a 10% wagering tax.
State auditors estimate this could bring in anywhere from $0 to $28.9 million annually. That wide range is exactly what the "No" side was screaming about. If the sportsbooks give away a ton of promotional credits to get people hooked, those credits get subtracted from the taxable revenue.
Still, the law mandates that the first $5 million collected every year goes straight to the Compulsive Gambling Prevention Fund. Everything after that is earmarked for Missouri’s public schools and higher education. Proponents like Bill DeWitt III, president of the St. Louis Cardinals, have been very vocal about this finally "keeping our money at home."
The Breakdown of Who Can Get a License
The amendment didn't just open the floodgates for everyone. It’s a structured rollout managed by the Missouri Gaming Commission.

- Each of the 13 state casinos can get a license.
- The 6 professional sports teams get their own licenses.
- Two "untethered" mobile licenses are available for companies that aren't tied to a physical casino or stadium.
It’s 2026: Is It Live Yet?
Yes. If you’re standing in Missouri right now, you can open an app and place a bet.
The law required the market to be live no later than December 1, 2025. The Missouri Gaming Commission actually hit that deadline. They opened the application window in May 2025, spent the summer vetting the tech and the companies, and then gave the green light for the official launch this past December.
It’s been a bit of a gold rush. In the first few weeks of operation, the "handle"—that's the total amount of money wagered—was massive, fueled largely by the NFL season. Analysts at BetMissouri saw a surge of over $60 million in the first week alone.
What You Need to Know Before You Bet
If you're looking to get in on the action, there are a few ground rules that didn't change with the vote.
- Age: You must be 21 or older. No exceptions.
- Location: You have to be physically inside Missouri state lines. The apps use geofencing that is surprisingly accurate. If you’re on a bridge halfway to Illinois, it might get cranky.
- College Sports: You can bet on college games, but Missouri has followed the lead of other states by banning "player props" for in-state college athletes. You can bet on Mizzou to win, but you can't bet on how many yards the quarterback will throw for. This is meant to protect student-athletes from harassment.
The Practical Next Steps
The Amendment 2 Missouri results changed the landscape of the state's sports culture forever. If you are planning to join the millions of Missourians already using these platforms, here is how to handle it:
- Check the License: Only use apps authorized by the Missouri Gaming Commission. If an old "offshore" site is still emailing you, ignore it. Those aren't regulated and won't contribute a cent to Missouri schools.
- Set a Limit: Every legal app in Missouri is required to have "Responsible Gaming" tools. Use them to set a weekly deposit limit before you even place your first bet.
- Watch the Deductions: If you're a tax hawk, keep an eye on the Gaming Commission’s monthly reports. These are public records. We’ll finally see in the coming months whether the "Yes" or "No" campaign was right about how much money actually makes it to the classrooms.
The era of driving across the border to Kansas just to bet on the Super Bowl is officially over. Missouri has joined the 38 other states in the legal market, and while the vote was a squeaker, the impact on the state budget and the local sports scene will be felt for decades.
