Missouri Sports Betting 2025 Guide – BetMGM & Online Sportsbooks

Missouri sports betting is finally becoming a reality.

After years of debate and watching neighboring states launch legal wagering, Missouri voters approved a constitutional amendment in 2024 to legalize sports betting. Regulators have now set December 1, 2025 as the official launch date for legal sports wagering in the state, both online and in person.

That means fans will soon be able to bet on the Kansas City Chiefs, St. Louis Cardinals, St. Louis Blues, St. Louis City SC, Mizzou, and more — without crossing state lines or using shady offshore sites.

This in-depth guide from 21Sports.com explains everything you need to know about Missouri sports betting and highlights BetMGM Sportsbook as one of the premier options for new bettors in the Show-Me State.

Use this page to understand the law, get educated on bet types, and learn exactly how to sign up with BetMGM Missouri once legal wagering goes live.

Is Sports Betting Legal in Missouri?

Yes. Sports betting is legal in Missouri.

In the November 2024 general election, Missouri voters narrowly approved a constitutional amendment (commonly referred to as Amendment 2) that:

Authorizes regulated sports wagering in the state
Allows online sports betting, mobile apps, and in-person sportsbooks at licensed locations
Restricts betting to adults 21+ who are physically located in Missouri at the time of the wager
Applies a 10% wagering tax to sportsbook revenue, with funds directed toward education and compulsive gambling prevention

Following the vote, the Missouri Gaming Commission began creating detailed regulations, reviewing license applications, and preparing for the full launch. The Commission has since confirmed that legal sports wagering in Missouri will begin December 1, 2025.

Why BetMGM Is a Top Choice for Missouri Sports Bettors

With several major brands entering the market, BetMGM Sportsbook stands out as one of the premier options for bettors in Missouri.

Here’s why BetMGM Missouri is expected to be a top sportsbook in the state:

1. Trusted National Brand

BetMGM is a joint venture between MGM Resorts International and Entain, and is already a leading legal sportsbook in many U.S. states. It’s known for:

A user-friendly app on iOS, Android, and desktop
Competitive odds across major leagues
Tons of betting markets and live betting options
Regular promotions, odds boosts, and loyalty rewards

2. Local Missouri Market Access

To operate in Missouri, online sportsbooks must either:

Partner with a licensed casino or professional sports team, or
Obtain one of a small number of “untethered” licenses

BetMGM has secured Missouri market access through a partnership with Century Casino & Hotel Cape Girardeau, giving it a strong local footprint and the ability to offer both online betting and, potentially, a retail BetMGM-branded sportsbook at that location.

3. Temporary License & Day-One Launch Plans

BetMGM has already been granted a temporary sports betting license by Missouri regulators, putting it on track to launch as soon as the market opens.

The expectation is that BetMGM Sportsbook will be ready to go on December 1, 2025, or very shortly thereafter, making it one of the first apps available to Missouri bettors.

4. Pre-Registration and Welcome Offers

Ahead of launch, Missouri is allowing pre-registration with licensed sportsbooks.

That means sports fans can:

Create a BetMGM Missouri account
Complete ID verification
Explore the app and possibly make a deposit

Actual betting will only begin once the market officially opens, but pre-registration often comes with exclusive early sign-up offers. Be sure to use the BetMGM Missouri link on 21Sports.com so you don’t miss out on any pre-launch or welcome promotions.

Where You’ll Be Able to Bet in Missouri

1. Online & Mobile Sportsbook Apps

The biggest shift for Missouri bettors comes with legal online sportsbooks. Once live, you’ll be able to download licensed apps like BetMGM Sportsbook, create an account, and bet from anywhere in the state with a secure internet connection (as long as you’re 21+ and pass geolocation checks).

Typical features you’ll see on BetMGM Missouri include:

Betting markets for all major U.S. and international sports
Live in-game betting with constantly updating odds
Same-game parlays and parlay builders
Personalized offers, boosts, and loyalty rewards
A polished, easy-to-use interface tailored for both new and experienced bettors

From a competitive standpoint, BetMGM will be one of several legal options in Missouri, but this guide highlights BetMGM as a featured sportsbook for 21Sports readers.

2. Retail Sportsbooks at Casinos & Sports Venues

Missouri’s sports betting framework also allows for in-person wagering at:

Licensed casinos / gambling boats
Certain professional sports betting districts connected to Missouri pro franchises

Through its partnership with Century Casino & Hotel Cape Girardeau, BetMGM may eventually offer a retail sportsbook inside the casino or nearby, giving fans a physical place to:

Place bets at windows or kiosks
Watch games on big screens
Enjoy food, drinks, and a “Vegas-style” game-day atmosphere

Who Can Bet on Sports in Missouri?

To bet legally in Missouri, you must:

Be 21 years of age or older
Be physically located within Missouri state lines at the time you place the bet
Use a licensed Missouri sportsbook, such as BetMGM Missouri

You do not have to be a Missouri resident. Visitors can sign up and bet as long as they are inside the state and meet the age requirement.

Sportsbooks verify eligibility by:

Checking your identity (name, address, date of birth, last four of your SSN, etc.)
Using geolocation technology on your device to confirm you’re in Missouri

Once legal wagering goes live, signing up with BetMGM Sportsbook Missouri should only take a few minutes.

Step 1: Visit 21Sports.com and Tap the BetMGM Sportsbook Link

Step 2: Download the BetMGM App or Use Desktop

BetMGM is expected to be available on:

Step 3: Create Your Account

You’ll be prompted to enter:

Full name
Date of birth
Email address and phone number
Home address
Last four digits of your Social Security number

These details help BetMGM:

Confirm you are 21+
Verify your identity to comply with state and federal regulations
Protect your account from fraud or impersonation

Step 4: Verify and Secure Your Account

BetMGM may ask you to:

Upload a photo ID
Confirm your email or phone number
Enable two-factor authentication (2FA) or similar security features

Taking a moment to secure your account up front makes future logins faster and safer.

Step 5: Deposit Funds

Once your account is verified, you can make a real-money deposit using methods BetMGM typically supports in legal states, such as:

Online banking / ACH
Debit cards
Prepaid cards
Popular e-wallets
Sometimes in-person cash deposits at retail partner locations

Only deposit what you can afford to lose, and consider setting deposit limits within the app.

Step 6: Place Your First Legal Bet

After launch:

Open the BetMGM Missouri app
Select your sport (NFL, NBA, MLB, NHL, soccer, college football, etc.)
Pick a game or event
Choose your bet type (moneyline, spread, total, parlay, etc.)
Enter your stake and confirm your bet

If you’re using a BetMGM welcome promotion, check the terms (minimum odds, eligible bet types, expiration dates) so your first wager lines up with the offer requirements.

Popular Types of Bets You’ll Find at BetMGM Missouri

To help newer bettors, here’s a quick overview of common bet types:

Moneyline: Pick which team will win the game outright.
Point Spread: Bet on a team to win by more than a certain number of points or to lose by fewer than that number.
Totals (Over/Under): Wager on the combined score of both teams going over or under a specified number.
Parlays: Combine multiple selections into one bet. All legs must win, but payouts are higher.
Same-Game Parlays (SGPs): Build parlays within a single game (e.g., Chiefs to win + total points + a player yardage line).
Futures: Long-term bets like “Chiefs to win the Super Bowl” or “Cardinals to win the NL Central.”
Player Props: Bets related to individual player performance (yards, points, goals, etc.). Missouri will have specific rules about college player props, particularly involving in-state schools.
Live (In-Game) Betting: Place bets as the game is unfolding, with odds updating based on what’s happening on the field or court.

BetMGM is known for offering a deep menu of props and live lines, which should translate nicely to Missouri once the market launches.

What Can You Bet on in Missouri?

Once Missouri sports betting goes live, you’ll be able to wager on a huge range of sports at BetMGM, including:

NFL – Kansas City Chiefs and every other NFL team
MLB – St. Louis Cardinals, Kansas City Royals, and league-wide action
NHL – St. Louis Blues and all NHL matchups
MLS & Global Soccer – St. Louis City SC, European leagues, international tournaments
NBA & WNBA – Full pro basketball slates
College Football & Basketball – Including Missouri Tigers (Mizzou) and other in-state programs
Golf, tennis, combat sports, motorsports, and more

College Sports Restrictions

Missouri’s law allows betting on college games, including in-state schools like Mizzou, but applies extra safeguards around college athletes. Expect restrictions on individual player prop bets involving Missouri college athletics. You’ll still be able to bet on team outcomes and many other markets, but some college props may be off the board.

No High School Betting

Like many states, Missouri prohibits bets on high school sports. You won’t find high school markets in the BetMGM Missouri app or at any regulated Missouri sportsbook.

Missouri Sports Betting Rules & Player Protections

To keep things safe and fair, Missouri’s legal market is built around a few core standards:

21+ Only: You must be at least 21 years old to bet.
In-State Only: Bets must be placed while you are physically located in Missouri.
Licensed Operators Only: Legal protection, secure payments, and responsible gambling tools apply only when you use state-licensed sportsbooks like BetMGM.
College Protections: Additional rules limit certain types of bets involving college athletes, particularly Missouri-based players.
No High School Wagers: High school sports betting is banned.
Responsible Gambling Measures: Operators are required to provide tools like deposit limits, time limits, self-exclusion, and clear access to help resources.

If there’s ever a dispute, using a regulated app like BetMGM means there’s a state regulator that can step in, something offshore sites simply can’t offer.

Taxes and Getting Paid on Your Winnings

This page isn’t tax advice, but here are some general points to keep in mind:

Missouri charges sportsbooks a 10% tax on their net sports betting revenue.
Your winnings from sports betting are considered taxable income under federal law and are generally subject to Missouri state income tax as well.
BetMGM’s account history makes it easy to track your bets and results, and you may receive tax forms if you hit certain thresholds.

Because everyone’s situation is different, it’s wise to consult a tax professional if you plan on betting larger amounts or have questions about reporting requirements.

Responsible Gambling in Missouri

Legal sports betting brings new entertainment — and new risks — especially for people vulnerable to gambling problems. Missouri’s system includes several support options:

Missouri Problem Gambling Helpline – 1-888-BETSOFF (1-888-238-7633)
Confidential, 24/7 support, plus referrals to free or low-cost treatment programs.
National Problem Gambling Helpline – 1-800-522-4700
Available nationwide with chat and text options.
Voluntary Self-Exclusion Programs
Missouri offers a “Problem Gambling List” that lets individuals voluntarily bar themselves from licensed casinos and, in many cases, related gambling privileges.
Built-In App Tools at BetMGM
BetMGM and other legal sportsbooks typically provide:
- Deposit, loss, and time limits
- Cool-off periods
- Permanent self-exclusion options

If sports betting stops feeling fun and starts feeling stressful, take a break and reach out for help. There’s no shame in asking for support; the system is designed to make it accessible.
