Investigation into crypto platform Polymarket after traders placed 500 million dollars on Trump’s Iran post
Last Updated on 25 March 2026 by CryptoTips.eu
Just before Donald Trump announced on Monday that the United States would ‘pause’ attacks against Iran for five days as peace talks were underway, various traders, including via the crypto platform Polymarket, bet approximately 500 million dollars on a drop of the oil price. The U.S. judiciary will therefore launch an investigation into insider trading.
🇺🇸 Just minutes before Trump's announcement of talks with Iran, massive trades hit the market.

In one move, $1.5 billion in S&P 500 futures were purchased. This trade was so large it sent the entire index +0.3% higher that minute.
$192 million in oil futures were also sold.… pic.twitter.com/RFBVRrrSBW
Insider trading
It is not the first time that rumors about ‘insider trading’ have circulated in the Trump camp. Last October, some 30 minutes before Trump announced that he wanted to impose a 100% import tariff on China, several accounts were opened on crypto trading platforms and millions in Bitcoin shorts were placed.
When Trump’s announcement followed, the price of Bitcoin rapidly dropped by 17% and one investor earned about 88 million dollars. The accounts were closed fairly quickly afterwards, and due to the anonymity of crypto, no one knows who entered the trades.
The phenomenon was also observed during the kidnapping of Venezuelan President Madura. At that time, a trader bet about $32,000 via Polymarket on a few very specific events occurring in Venezuela, just before they actually happened.
Oil price
This time, however, the effect of the bets is much greater, and hundreds of millions of dollars were earned.
A trader at Polymarket placed a bet on 5 events in Iran, all of which were confirmed by the Trump post that occurred 15 minutes later. He earned a million dollars this way.
