Missouri’s new sports betting law,
, creates a legal framework for professional sports teams to host
in-person sportsbooks
at or near their home venues. While actual sports betting operations in Missouri have yet to
launch, the law opens the door for betting lounges and on-site wagering at major stadiums like Arrowhead and Busch Stadium.
Here’s how it works.
What Is a “Designated Sports and Entertainment District”?
Section 313.1000(10) of SB 643 defines a “designated sports and entertainment district” in two ways:
(a)
“Any area within this state that is a designated entertainment district as of the effective date of sections 313.1000 to 313.1024... The boundaries of such district shall not be enlarged or otherwise modified after the effective date.”
(b)
“The premises of a facility located in this state with a seating capacity of seventeen thousand five hundred people or more, at which one or more professional sports teams plays its home games, and the surrounding area within four hundred yards of such premises.”
In short, if a stadium hosts a pro team and holds at least 17,500 people, it qualifies—along with the 400-yard radius around it.
Which Missouri Stadiums Qualify?
The law doesn’t name venues, but the seating and usage requirements clearly apply to:
-
Arrowhead Stadium
(Kansas City Chiefs,
NFL)
-
Busch Stadium
(St. Louis Cardinals,
MLB)
-
Kauffman Stadium
(Kansas City Royals,
MLB)
-
Enterprise Center
(St. Louis Blues,
NHL)
-
CITYPARK
(St. Louis City SC,
MLS)
Each of these venues meets the 17,500+ seating threshold and regularly hosts professional teams. Once the Missouri Gaming Commission issues guidance and begins licensing, these locations will be eligible for on-site
sportsbooks.
How the Law Protects Team Marketing Rights
One of the most powerful provisions of SB 643 is the control it gives teams over sportsbook activity within their districts. Section 313.1003.3 states:
“Sports wagering commercial activity shall be prohibited from being conducted within any designated sports and entertainment district by or on behalf of any person or entity that directly or indirectly offers sports wagering… except to the extent such prohibition is waived in writing by the designated sports and entertainment district entity.”
In plain English: no sportsbook can advertise or operate inside a stadium or its 400-yard radius unless the team—legally defined as the
designated sports and entertainment district entity—gives them written permission.
This allows teams to:
-
Approve or deny marketing partnerships with sportsbooks
-
Retain exclusive rights to offer wagering on their grounds
-
Prevent unauthorized ads, promotions, or kiosks in their district
What Happens Next?
While the law is in place, teams and sportsbooks can’t begin operating until licenses are issued. SB 643 gives regulatory authority to the Missouri Gaming Commission, which must now create rules, review applications, and certify facilities.
“The commission shall adopt rules to implement the provisions of sections 313.1000 to 313.1024.” (Section 313.1004.1)
Until those rules are finalized, no legal in-stadium sportsbook can open. But when implementation begins, Missouri’s top sports venues are already in line to benefit.
Final Word
SB 643 doesn’t just legalize sports betting in Missouri—it creates a new model where pro teams can integrate wagering directly into the stadium experience. With legal rights over their own districts, teams will be able to control which sportsbook brands can operate in their spaces, likely creating premium, exclusive betting environments once the commission gives the green light.
