Polymarket US is backing away from a prediction market tied to Patrick Mahomes’ return, while another operator is keeping its version of the market live.
The issue centers on whether Mahomes will play in the Kansas City Chiefs’ Sept. 14 game against the Denver Broncos at Arrowhead Stadium. Mahomes has checked off all of his rehab goals so far, and he has said his aim is to be ready for Week 1. That has left Broncos fans, and plenty of others watching the market, with a pretty clear view of what they think happens next.
But they won’t be able to turn that belief into a trade on Polymarket US. According to a report from David Purdum of ESPN, the company is withdrawing plans to offer trading on Mahomes’ return after following guidance from a federal regulator.
The question that was initially offered was: "Will Patrick Mahomes participate in the Kansas City Chiefs ' Week 1 regular-season game?" That filing has now been pulled.
The regulatory body involved is the Commodity Futures Trading Commission, which asked Polymarket and other prediction market operators to remove contracts like the one involving Mahomes in Week 1. Polymarket withdrew the filing to comply and says it will keep working with the agency on staying in line with those rules.
Kalshi, though, is taking a different route. The company is still offering trading on Mahomes, along with other markets tied to when injured players will return. Per the ESPN report, Kalshi did not respond to any CFTC direction on those markets.
The NFL wants the CFTC to go further. Jeff Miller, the league’s executive vice president of affairs, said Wednesday at the NFL owners meeting in Atlanta that he hopes the agency will prohibit these kinds of markets and set up a review process before they go live.
"We hope to get to the place where we have a very efficient system someday if they're legalized in that same way that we can protect the integrity of the competition perfectly," Miller said Wednesday at the NFL owners meeting in Atlanta.

Broncos Just Made Final Cuts A Lot Tougher Than Expected
The Broncos closed the preseason with a 34-6 rout of the Vikings, and the lopsided finish only sharpened the pressure on the front office as the roster deadline approaches. What had looked like a fairly straightforward trimming exercise suddenly has a few more names in the mix, thanks to backup performances that stood out when the stakes were highest for fringe players trying to survive the final round of cuts.
Sam Ehlinger and Cody Schrader both turned in notable outings that will make the conversation a lot more interesting over the next few days, while Marvin Mims Jr. left with a foot bruise but is expected to recover. Not everyone helped his case, either, as Barron struggled and could be staring at a tougher path than he seemed to have going into the finale, which is exactly the kind of late twist that can turn a routine cutdown into a real debate.

Marvin Mims Jr. Just Put A Broncos Decision Back In Play
Marvin Mims Jr.s preseason debut for the Broncos was over almost as soon as it began against the Vikings, and the quick exit put an immediate spotlight back on his role in Denver. Mims was escorted to the sideline and then to the locker room after suffering a foot injury at the end of the first drive, a frustrating turn for a player whose speed and return ability have been part of the conversation around his place on the roster.
The timing matters because Mims has been viewed as one of the players who could shape Denvers decision-making at returner, and any injury concern naturally spills over into bigger questions about availability and contract talks. The Broncos do have other options if Mims is limited, which gives the team some insurance, but it also leaves a key special teams discussion hanging while the injury picture sorts itself out.

Kolbe Katsis Just Made The Broncos' Easiest Cut A Real Problem
Sean Payton reached for a little pop-culture theater before the preseason game, borrowing an analogy from The Voice to push his players into the spotlight. For a Broncos roster still taking shape, that kind of message fit the moment. Denver has long been willing to keep undrafted free agents around if they earn it, and wide receiver Kolbe Katsis has done exactly what an uphill roster candidate needs to do by standing out when the games started counting for evaluation.
Katsis made his case in the preseason, and the loudest part of it came in the return game, where his work on kickoff and punt returns gave the Broncos something useful to think about at two spots at once. Wide receiver depth is always part of the calculation, but so is the return specialist job, and Katsis has put enough on tape to make what looked like an easy cut a little less simple. Denver still has to sort out the final roster, but his performance has created a real conversation where there may not have been one before. [Read more 🡒]
