At 3:40 in the morning, while most of Wall Street was asleep and crude oil screens were barely moving, somebody made a wager large enough to wake up the market. Nearly 10,000 crude oil futures contracts were sold short in a trade valued at roughly $920 million. No public statement had been made. No White House briefing had aired. No leak had surfaced on financial terminals. Oil traders staring at overnight charts saw a giant sell order hit the market with almost theatrical timing.
Seventy minutes later, Axios reported that the United States and Iran were nearing a 14-point memorandum aimed at ending the war that had rattled energy markets for more than two months. Oil prices collapsed almost immediately.
By the time most traders reached their desks in New York, Brent crude had fallen as much as 12%, while West Texas Intermediate dropped more than 13%. The trader or traders behind the overnight short position were sitting on an estimated $125 million profit in less than four hours.
Now the trade is attracting the attention of federal investigators.
According to people familiar with the matter, the Justice Department and the Commodity Futures Trading Commission have opened investigations into a series of oil futures trades placed shortly before market-moving announcements tied to the Iran conflict. Investigators are also looking at activity on prediction-market sites where traders placed bets connected to military and diplomatic developments in the region.
The inquiries remain in early stages, and investigators have not accused anyone of wrongdoing. But the timing of several trades has raised enough concern that federal authorities are now examining whether confidential information may have circulated before it became public.
The inquiry reportedly includes at least four trades made in March and April that generated more than $2.6 billion in combined gains from bets that oil prices would fall.
The latest trade may become the most closely watched of them all.
The overnight position appeared just before reports that Washington and Tehran were nearing an agreement that could cool the war and reopen shipping lanes through the Strait of Hormuz. Oil traders had spent weeks pricing in fear. Tankers faced attacks. Insurance costs jumped. The possibility of wider regional fighting pushed crude sharply higher through much of the spring.
Then came the sell order.
For veteran commodities traders, the timing was impossible to ignore. Large oil positions do not appear out of thin air during thin overnight trading unless somebody has very strong conviction. Traders hedge exposure all the time, but a nearly billion-dollar directional bet placed before dawn carries a different smell altogether.
“This is not normal positioning,” one New York energy trader said privately after the market collapse. “Somebody either knew something or got extremely lucky.”
That question now hangs over the futures market.
A Market That Moved Before the News Did
The market reaction to the Axios report was swift because the war itself had become one of the biggest forces driving oil prices this year.
Since military operations involving the United States, Israel, and Iran escalated earlier this spring, crude prices had surged nearly 40%. Traders feared disruptions to shipping routes through the Strait of Hormuz, the narrow passage that carries roughly one-fifth of the world’s oil supply.
When reports surfaced that Washington and Tehran were nearing a memorandum that could reopen maritime access and ease military tensions, traders rushed to dump oil contracts.
But what unsettled many market participants was not the price collapse itself. It was the fact that somebody appeared positioned for it before anyone else had the story.
Online market watchers began circulating screenshots of the futures activity within hours. The Kobeissi Letter, a financial commentary account widely followed by retail traders and hedge fund managers alike, highlighted the timing in a post that quickly spread across trading circles.
Former JPMorgan quant executive Marko Kolanovic added fuel to the discussion by describing markets as “blatantly manipulated” in a social media post reacting to the move.
Even seasoned oil traders struggled to explain the size and timing of the position through ordinary market logic.
At 3:40 a.m. Eastern Time, liquidity in crude futures is usually far thinner than during regular U.S. trading hours. Large positions can move prices sharply and attract immediate attention from brokers and rival trading desks. Anyone placing a trade that size knows the market will notice.
Yet there were no public diplomatic headlines at the time.
That absence is now central to the federal inquiry.
Investigators are reportedly examining whether traders may have received early access to government discussions, diplomatic contacts, media reports, or confidential market intelligence before the Axios article became public.
Federal prosecutors are said to be coordinating with commodities regulators and reviewing trade records connected to the overnight activity. The probe is being led by the U.S. Attorney’s Office for the Southern District of New York, according to people familiar with the investigation.
Neither the Justice Department nor the CFTC has publicly commented in detail on the matter.
The exchanges involved have also kept quiet. CME Group, which owns NYMEX, declined to comment. Intercontinental Exchange, which handles Brent crude futures trading, also declined public comment.
The silence has only added to the speculation.
Oil Traders Have Seen This Pattern Before
This was not the first suspiciously timed oil trade linked to the Iran war.
Market analysts have pointed to several large positions placed shortly before major developments in the conflict. One trade reportedly worth $950 million appeared before an April announcement tied to ceasefire negotiations. Another $760 million oil position surfaced minutes before separate headlines that moved crude prices sharply lower.
Individually, each trade might be dismissed as aggressive speculation. Together, they paint a picture that investigators now appear unwilling to ignore.
Prediction markets have also entered the spotlight. Federal authorities are examining unusual betting activity tied to diplomatic and military events involving Iran. Traders on those platforms can place wagers on outcomes ranging from ceasefires to military strikes, often reacting faster than traditional financial markets.
The line between informed speculation and illegal insider trading becomes murkier when geopolitical information enters the picture.
Unlike earnings reports or corporate mergers, war-related intelligence often circulates through diplomats, military officials, contractors, journalists, foreign governments, and private analysts before reaching the public. Information leaks in fragments. Rumors spread quietly across embassies, trading desks, encrypted chats, and political circles long before headlines appear on television.
That makes proving wrongdoing difficult.
A trader can legally form a view based on public signals, diplomatic chatter, satellite imagery, tanker movements, or political analysis. But if somebody traded using confidential government information or privileged access to unpublished reporting, prosecutors may view the situation very differently.
So far, investigators have not publicly identified any trader, fund, or institution tied to the overnight short.
Meanwhile, the diplomatic situation itself remains unstable.
Iranian officials have publicly pushed back on parts of the reported agreement, calling some proposals unrealistic. President Donald Trump has sent mixed signals, at times warning of renewed military action while also signaling interest in negotiations.
Oil prices have swung violently with each new statement.
After the initial crash Wednesday morning, prices partially recovered when Iran announced tighter control measures in parts of the Persian Gulf shipping corridor. Traders who had rushed into bearish bets suddenly faced sharp reversals as uncertainty returned to the market.
That volatility only reinforced how sensitive oil has become to headlines, leaks, and rumors tied to the war.
