In the young and competitive world of prediction markets, where platforms that let people wager on the outcomes of elections and economic data are still earning their credibility, Kalshi has chosen to end its advisory relationship with Donald Trump Jr., citing a conflict tied to its rival Polymarket. The account, reported by Reuters on November 12, 2026, comes from Kalshi alone, and the particulars of that conflict remain outside the public view.

Kalshi Says It Ended Donald Trump Jr.'s Advisory Contract Over Polymarket Conflict
Kalshi says it ended the contract, and says Polymarket is the reason.
Mark
So what actually happened here?
Mimi
Kalshi says it ended Donald Trump Jr.'s advisory contract, and it points to a conflict involving Polymarket, its rival.
Mark
Why would that be a conflict?
Mimi
That's the part we don't have. The reporting says Polymarket is the source of the conflict, not how.
Luke
And that's worth stressing. Everything here is Kalshi's account. We have no statement from Trump Jr. or from Polymarket in what we've been given.
Mark
Does the timing of the termination matter?
Luke
It would, but the material doesn't say when the contract ended. I won't guess at a date.
Mimi
What does come through is why advisers matter in this business. Two competing platforms, and a recognizable name tied to one of them.
Mark
Could regulators care?
Luke
Possibly, but that's a thing to watch, not something reported. Nothing here says any regulator is looking.
Mimi
So the honest summary is a company saying it cut a tie, with the reasons still thinly explained.
O Pulso
- Kalshi has cut ties with Donald Trump Jr. over a conflict tied to rival Polymarket, and the reason has not been fully explained.
- The split lands in a tight market where rival platforms fight for trust, and famous advisers carry real weight.
- Kalshi's own account is the only voice so far, leaving the nature of the conflict and the terms of the deal unclear.
- Trump Jr. and Polymarket have not yet responded, and the story is waiting on their answers.
- Attention now turns to whether regulators will examine how advisory ties in prediction markets are structured and disclosed.
In the young and competitive world of prediction markets, where platforms that let people wager on the outcomes of elections and economic data are still earning their credibility, Kalshi has chosen to end its advisory relationship with Donald Trump Jr., citing a conflict tied to its rival Polymarket. The account, reported by Reuters on November 12, 2026, comes from Kalshi alone, and the particulars of that conflict remain outside the public view. What is clear is that a well-known name, valued for the standing it lends, has been set aside because it could not comfortably sit between two competitors.
Kalshi, the prediction market platform, says it has ended its advisory contract with Donald Trump Jr. The company points to a conflict connected to Polymarket, its direct competitor. Reuters first reported the decision as an exclusive on November 12, 2026.
The explanation comes entirely from Kalshi. The company says the arrangement is over and names Polymarket as the cause, but it has not described how the conflict arose, what Trump Jr.'s work with Polymarket involves, when the contract ended, or what his advisory role had covered.
The decision matters because prediction markets are still a young industry, where rivals compete for credibility and attention and well-known advisers help supply both. An adviser tied to two competing platforms creates an awkward position, and Kalshi's move suggests it considers that overlap disqualifying.
What comes next is still open: whether Trump Jr. or Polymarket responds, whether more details about the conflict emerge, and whether the episode prompts scrutiny of how these advisory relationships are structured and disclosed.
Kalshi, the prediction market platform, says it has ended its advisory contract with Donald Trump Jr. The company's stated reason is a conflict tied to Polymarket, a rival prediction market. Reuters reported the development as an exclusive on November 12, 2026.
The account comes from Kalshi itself. The material available says the company terminated the arrangement and points to the Polymarket conflict as the cause, but it does not lay out the mechanics of that conflict. It does not say what Trump Jr.'s role with Polymarket involves, when the contract ended, or what the advisory work consisted of.
The actors are few. Kalshi is one of the two best-known venues where people trade on the outcomes of events, from elections to economic data. Polymarket is its direct competitor. Donald Trump Jr. had an advisory relationship with Kalshi, and according to Kalshi, that relationship is now over because of his tie to the competing platform.
What is established is narrow: Kalshi says it ended the contract, and says Polymarket is the reason. What is not established in the material at hand is any response from Trump Jr. or from Polymarket, the financial terms of the contract, or whether the decision was contested. Because the claim rests on one party's description, the characterization of a conflict is Kalshi's own.
The story matters because prediction markets are a young industry in which rivals compete for credibility and attention, and well-known advisers lend both. An adviser who holds ties to two competitors sits awkwardly in that arrangement, and Kalshi's decision shows the company treating that overlap as disqualifying.
What to watch next is straightforward: whether Trump Jr. or Polymarket responds, whether more detail emerges about the nature of the conflict, and whether the episode draws regulatory attention to how advisory relationships in prediction markets are structured and disclosed.
