A string of $500M–$950M trades has sparked insider trading investigations and raised concerns about possible market manipulation.
Dubai: A series of unusually timed oil trades totaling more than $1 billion is under scrutiny from U.S. regulators and lawmakers, as they were placed just ahead of major war-related announcements that drove global prices sharply lower.
These were not routine moves. They involved large, high-risk bets in financial markets where investors aim to profit by predicting future price movements.
Reuters, Bloomberg, the Financial Times, and The Guardian have all reported multiple cases in which traders appeared to take positions just ahead of major developments during the Iran conflict.
The key question is whether these trades reflect sharp market insight—or access to information that had not yet been made public.
$760M ahead of Hormuz news
The clearest example came on April 17, when investors placed a roughly $760 million short position—effectively a bet that oil prices would fall—about 20 minutes before a major announcement.
Data from London Stock Exchange Group showed that 7,990 Brent crude futures contracts—agreements to buy or sell oil at a fixed price on a future date—were sold between 12:24 and 12:25 GMT.
At 12:45 GMT, Abbas Araghchi—Iran’s foreign minister and top diplomat—announced on X that the Strait of Hormuz, a narrow passage through which a large share of the world’s oil supply flows, was “completely open” following a ceasefire.
The market reaction was immediate. Brent crude, the global benchmark for oil prices, fell from above $100 to around $88 per barrel. U.S. crude dropped about 10%, meaning traders who had bet against the market stood to profit.
LSEG analysts said the trading burst was “completely atypical for that period,” with volumes nearly nine times higher than normal.
Pattern keeps repeating
The April 17 trade was not an isolated event. Reuters and Financial Times reported two earlier cases:
- In early March, traders placed about $500 million roughly 15 minutes before the White House delayed planned strikes on Iran’s energy sector.
- On April 7, investors positioned about $950 million on falling oil prices around three hours before a U.S.–Iran ceasefire announcement.
These trades took place in the oil futures market, where investors buy and sell contracts based on where they expect prices to move.
The April 7 trade involved exactly 6,200 Brent contracts—matching volumes seen in the earlier March spike. Each time, prices moved in the direction of those financial bets soon after the announcements became public.
Predicting with precision
The same timing patterns have surfaced across multiple online platforms. Reports from The Guardian and The New York Times indicate that traders placed highly accurate wagers on geopolitical events before they unfolded. On February 27, around 150 accounts staked $855,000 predicting U.S. airstrikes on Iran the following day.
Sixteen of those accounts reportedly made more than $100,000 each. Soon after, a user on Polymarket—a site where people bet on real-world outcomes—made over $550,000 after predicting that Ali Khamenei would be removed from power shortly before he was killed in an Israeli strike.
A complaint filed with the Commodity Futures Trading Commission by Public Citizen cited a crypto analytics firm that identified six “suspected insiders” who made a combined $1.2 million from similar predictions.
On April 7, at least 50 accounts again predicted a ceasefire hours before it was announced. These financial bets, along with the oil trades, “accurately predicted the precise timing of major developments,” according to the complaint—raising concerns about insider trading, where non-public information is used for financial gain.
Regulators demand answers
The repeated timing has drawn scrutiny in Washington. Ritchie Torres has called on the Securities and Exchange Commission and the Commodity Futures Trading Commission to investigate.
Craig Holman of Public Citizen told Bloomberg: “It is difficult to believe they would place that amount of money, moments before an official announcement, based on simple chance.”
He added: “We are looking at a potential cross-market synchronized signal that suggests someone in the room is talking to the traders.” Reuters and Bloomberg reported that the CFTC has begun examining some of the trades, though it has not publicly confirmed a formal investigation.
Hard to prove insider trading
Experts say the issue is being complicated by the rapid growth of financial prediction markets. Platforms like Polymarket and Kalshi allow users to bet on the outcomes of political decisions, conflicts, or economic events.
Craig Holman described the sector as being in “a wild west phase… now it’s spilled over into the stock market as well.” Even when trades appear suspicious, proving wrongdoing is complex.
Much of the activity takes place through anonymous or crypto-based systems, where identities are obscured and transactions can be difficult to trace.
Andrew Verstein told The Guardian: “We can’t say from the outset whether any of these trades were illegal… but many of them bear the hallmarks of suspicious trades that would naturally warrant investigation.”
Joshua Mitts added that enforcement faces practical limits: “To have a law that can’t really be enforced effectively… it’s sort of putting the cart before the horse.”
His research found traders linked to suspicious activity achieved nearly a 70% success rate, generating $143 million in profits from well-timed wagers.
High stakes for markets
The Strait of Hormuz plays a critical role in global energy supply, making any disruption—or reopening—a major market-moving event. Its closure during the conflict pushed oil prices above $100 per barrel, while its reopening triggered a sharp decline.
Overall, the situation highlights the blurred line between sharp market foresight, prediction markets, and the growing regulatory challenge of determining when timing crosses into potential misuse of non-public information.
But analysts say the bigger concern now is not just price volatility. If traders are consistently able to position themselves before major announcements, it raises questions about whether global markets are operating fairly—or whether some participants are trading with an unseen informational advantage.
For regulators, the issue goes beyond oil prices. It is about whether global markets are truly reflecting publicly available information—or whether major decisions are being absorbed into prices before the public is aware of them.
