A sequence of well-timed market bets and concentrated prediction-market wagers took place just prior to several major policy steps attributed to U.S. President Donald Trump, according to trading and blockchain data. In each instance, large positions were established ahead of public announcements that then moved prices sharply - from oil and equities to sovereign debt - prompting scrutiny of whether information had been known in advance by some market participants.
April 7, 2026 - Ceasefire announcement and heavy crude selling
Hours before the public statement announcing a two-week ceasefire between the U.S. and Iran, traders sold a large volume of crude contracts. Roughly $950 million in bets that oil prices would fall were executed just before the announcement. LSEG data shows a combined 8,600 lots of Brent and U.S. crude futures were sold at 1945 GMT on that Tuesday. The public announcement came at around 2230 GMT and crude futures subsequently fell about 15%, ending below $100 a barrel at the start of the following official trading session.
At the same time, activity on prediction-market platforms also caught attention. A group of recently created accounts placed timely "Yes" wagers on whether a ceasefire would be reached on April 7. Blockchain-based analytics of that platform indicated at least 50 accounts or wallets made such bets before the social-media post announcing the ceasefire. Several wallets showed concentrated, profitable activity: one wallet created around 10:00 a.m. ET on the same day profited $200,000 after staking about $72,000; another account created on April 6 realized $125,500 in gains; a third wallet, opened roughly 12 minutes before the announcement, earned an estimated $48,500 from a stake of $31,908. The prediction-market operator did not respond to a request for comment.
March 23, 2026 - Large crude bets ahead of attack pause
On March 23, a concentrated, high-volume block of trades on Brent and WTI futures occurred in the minute before a presidential announcement delaying attacks on Iran's energy infrastructure. Exchange data and subsequent calculations indicate roughly $500 million in futures were transacted in that brief window. LSEG shows 5,100 lots changed hands between 1049 and 1050 GMT, with selling dominating the minute’s flow.
When the president’s social-media post announcing a five-day pause to planned strikes was posted at 1105 GMT, trading surged: more than 13,000 lots - equivalent to roughly 13 million barrels - exchanged hands in 60 seconds, and crude prices plunged. Brent dropped to $99 per barrel from $112, while WTI fell to $86 from $99.
February 28, 2026 - Prediction-market wagers and Iran strikes
Wagers placed on prediction platforms before the strikes that led to the death of Iranian Supreme Leader Ayatollah Ali Khamenei intensified scrutiny of markets that allow bets on geopolitical events. Democratic lawmakers called for prohibitions on markets that could reward those with privileged information about military operations.
One market operator is facing a legal claim alleging it failed to pay $54 million to people who had bet that Khamenei would leave office before March 1. That operator contends it does not offer markets that settle on death.
A contemporaneous review of prediction-market listings showed about $529 million wagered on a range of contracts tied to the timing of U.S.-Israeli strikes on Iran, and another $150 million staked on the possibility of Khamenei’s removal as supreme leader. Analytics from a separate blockchain-tracking firm identified six accounts that together made roughly $1.2 million in profits from bets funded in the hours immediately prior to the raids, which took place on February 28. One U.S. representative highlighted a specific bet on that platform placed shortly before the strikes.
In related market moves, despite inflation data that would normally prompt investors to sell long-dated U.S. Treasuries, traders instead moved into those safe-haven assets on February 27, pushing yields on the benchmark 10-year note below 4%. On the same day, U.S. airline shares dropped amid rising oil prices; the Dow Jones U.S. Airlines Index fell 5.13%.
January 3, 2026 - Bets preceding capture of Venezuela’s former president
An unnamed trader made an estimated profit of about $410,000 after wagering on the ouster of Venezuelan President Nicolas Maduro. The trader’s account on the prediction market built positions on contracts tied to Maduro’s removal that implied long odds prior to a weekend raid on the Caracas compound by U.S. special forces. Those positions, which had a value of approximately $34,000 before the operation, rose sharply in value once news of the U.S. military operation emerged on January 3.
April 9, 2025 - Options activity ahead of tariff pause
In April of last year, unidentified options traders placed large wagers betting on a sharp rebound in U.S. equities just minutes before the president’s tariff pause post, an event that sparked a sizable market rally. The post pausing tariffs went live at 1:18 p.m. ET on April 9 and coincided with a roughly 9.5% jump in the S&P 500.
Market data show an unusual spike in certain options contracts ahead of the public message. Some 5,105 SPY call options traded at about 1:00 p.m. ET for an average price of $4.20. When the market rallied, those calls increased in value to as high as roughly $42, turning about $2.14 million into paper gains of approximately $21.44 million. Other SPY calls that profited from a move above $509 traded around 1:10 p.m. ET; their value rose to about $10 million by the end of the day from an initial $624,000 position.
It was not possible to determine whether the call activity represented purchases or sales by a single trader or multiple participants, or whether the positions were closed for a realized gain. A White House spokesman, Kush Desai, noted that government ethics guidelines bar federal employees from profiting from nonpublic information and said: "Any implication that Administration officials are engaged in such activity without evidence is baseless and irresponsible."
Questions and market consequences
Across these episodes, similar patterns emerge: large, concentrated trades or prediction-market wagers placed shortly before public announcements that then triggered sharp price moves. The positions affected a range of instruments - crude oil futures, SPY options, prediction-market contracts, and U.S. Treasuries - and led to pronounced and rapid shifts in market prices on announcement. Lawmakers and market analysts have pointed to these patterns as a reason to scrutinize information flows and market oversight for platforms that allow bets on real-world policy or military events.
While the trades and wagers are documented in exchange and blockchain records, public commentary from platform operators has been limited in some cases, and questions remain about the identity of traders and whether positions were taken with privileged knowledge. The trading flows described above show how tightly timed transactions can coincide with policy developments and produce outsized market moves across energy, fixed income and equity sectors.
