Leave it to DonJr to invent insider betting –Prediction market trader 'Magamyman' made $553,000 on death of Iran's supreme leader
An account trading under the username "Magamyman" made more than $553,000 placing bets on the prediction market Polymarket that Iran's Supreme Leader, Ayatollah Ali Khamenei, would be out of power just before an Israeli strike killed him on Saturday.
The trades drew scrutiny from members of Congress and critics of prediction markets, who say the platforms invite people with access to classified information to profit on lethal military operations. On Polymarket alone, half-a-billion dollars was traded over when exactly U.S. forces would drop bombs on Iran.
"It's insane this is legal," Sen. Chris Murphy (D-Conn.) wrote on X. "People around Trump are profiting off war and death," he said, adding he plans to introduce legislation "asap" to outlaw this kind of activity.
The White House denied anyone in Trump's orbit was behind the lucrative trades.
The Trump family, however, does have ties to Polymarket. Donald Trump Jr., the president's son, is an adviser to Polymarket and his venture capital firm 1789 Capital has invested millions into the controversial business. The Trump administration has dropped two federal investigations into Polymarket that were opened by President Joe Biden's officials.
It's the latest episode igniting debate about how government and military insiders can monetize state secrets.
In January, an anonymous trader made hundreds of thousands of dollars for placing suspiciously well-timed bets ahead of the arrest of Venezuelan leader Nicolás Maduro. A month later, authorities in Israel charged two people for using classified information to place bets on Polymarket about upcoming attacks on Iran when the countries fought a 12-day war last June.
The millions flowing into the market related to the toppling of Iran's supreme leader were made on an overseas exchange operated by Polymarket, meaning it is outside the reach of regulators in Washington.
The Trump administration has granted approval for Polymarket to open a U.S.-based platform, but it has yet to fully publicly launch. Most American traders who use Polymarket access the site through a virtual private network that shields a user's identity and location.
Most prediction markets, which have surged in popularity in recent months, are federally regulated by the Commodity Futures Trading Commission. The agency views this new-fangled form of betting a "futures contract," not a type of gambling.
Under U.S. commodity trading laws, making trades based on death and war are illegal, since those kinds of bets create a financial reward for violence, human suffering and geopolitical instability.
This constraint was on display over the weekend in the way another major prediction market, Kalshi, responded to a market tied to when Khamenei would be out, a prospect that attracted more than $54 million in trades.
When Khamenei's death was confirmed, those who placed bets on Kalshi on the leader's ouster expected a payout, but it never happened. Instead, trading on the market was paused while the company conducted a "further review of the situation."
Later, Kalshi CEO Tarek Mansour wrote on X that the company would be refunding fees collected on the Khamenei market.
"We don't list markets directly tied to death," Mansour wrote. "When there are markets where potential outcomes involve death, we design the rules to prevent people from profiting from death. That is what we did here."
