Polymarket’s growing visibility in sports was one of the clearest takeaways from a new gambling industry roundup, which said MLB TV’s “Big Inning” stream was presented by Polymarket as part of the league’s deal with the prediction market platform.
The roundup, published by _The Closing Line_, also collected several other developments across sports betting and prediction markets, including a FanDuel fine in Iowa, a court setback for Kalshi in Connecticut, and new deposit limits for Colorado online sportsbooks.
Polymarket’s MLB presence adds to prediction market scrutiny
According to the roundup, the authors saw MLB TV’s “Big Inning” presented by Polymarket, underscoring how visible prediction market branding has become in a mainstream sports setting.
That item landed alongside another MLB-related controversy. The roundup said Congress is asking MLB to take action after a Bryce Harper betting video, pointing to continuing scrutiny around how betting and sports leagues intersect.
For players and sports fans, the bigger picture is that prediction markets and gambling-related products are drawing attention not just from customers, but also from lawmakers, courts, leagues, and responsible gambling groups.
FanDuel, Kalshi, and state regulators all saw new movement
The roundup said the Iowa Racing and Gaming Commission fined FanDuel a total of $95,000 for two sports betting violations. It did not specify in the summary whether those violations involved customer harm or were self-reported.
Kalshi also appeared in multiple items. The roundup said a Connecticut court rejected Kalshi’s injunction request in its legal fight over sports prediction markets, with the court characterizing the contracts as, “at bottom, they are sports wagers.” It also said the Nevada Council on Problem Gambling intends to sever ties with the National Council on Problem Gambling over the national group’s partnership with Kalshi.
Elsewhere, the roundup said Colorado online sportsbooks must stop accepting credit card deposits and limit customers to six deposits per gaming day starting Aug. 12.
What to watch
The source raised several unresolved questions, including what Congress wants MLB and the MLB Players Association to do beyond the Bryce Harper example, what the Connecticut ruling means procedurally for Kalshi, and what FanDuel’s Iowa violations involved in detail.
For bettors, these developments are worth watching because they show how quickly the rules, oversight, and public treatment of sports betting and prediction markets can shift across the U.S. As always, gamble responsibly.
