Kalshi CEO Tarek Mansour apparently thinks Polymarket head Shayne Coplan sucks. Coplan seemingly feels the same about Mansour. Good news, fellas: You’re both right!
A new report from NPR highlights tension between the heads of the two biggest prediction markets in the business, both of which are run by guys who don’t seem to care for their competition. And while their dick measuring contest has been something of a public endeavor, the report suggests that it’s even worse behind the scenes.
Kalshi’s Mansour has been the more willing of the two to acknowledge the relationship between himself and Polymarket’s Coplan, and has called it a Tom Brady/Peyton Manning-style rivalry. So like, imagine if instead of comparing passing yards and touchdowns, Brady and Manning vied to see who could produce the highest amount of trading volume on war crimes.
But even with the generous analogy, Mansour is apparently way less playful about the whole thing behind the scenes. NPR talked to a former Kalshi employee who described the culture at the company as being “die-hard,” and said that Mansour endlessly pushes his staff to hit new highs for user sign-ups and other metrics in an effort to chase Polymarket. (By some metrics, Kalshi has caught up and surpassed Polymarket in recent months on trading volume.) Coplan, meanwhile, hasn’t bothered to really acknowledge Mansour or the cold war between them, though it is reportedly a big part of his professional drive. NPR described him as “raging” about Mansour to his inner circle.
The feud has played out in some pretty petty ways. Both companies ran “free” grocery store promotions in New York City where they handed out food to long lines of people, effectively turning people in need of some support into props. Both companies have filed trademark applications with the US Patent and Trademark Office in which they lay claim to the title “the world’s largest prediction market.” Good luck to whoever has to make the call on that.
But it’s where the companies have diverged that seems like a real major point of tension. Kalshi has taken the position of an upstanding, Commodity Futures Trading Commission-regulated entity that has gotten all the proper licensing to operate in the US. Polymarket, meanwhile, is still jumping through hoops to operate legally in the US after previously being banned. And frankly, it doesn’t really seem like anyone placing bets on prediction markets cares all that much about legality, so it’s not clear the distinction matters to anyone other than the companies themselves.
It certainly doesn’t seem like it matters to the Trump administration, which has backed prediction markets on the federal level in the face of state-level bans. Of course, that’s probably because Donald Trump Jr. serves as an advisor to both companies. Maybe he can bring Mansour and Coplan together in mutual agreement that he seems like a terrible hang.
