Trump criticizes the world as a "casino," yet "front-running trades" frequently occur: policies move before announcement, market manipulation suspicion heats up

BlockBeats News, April 24 — U.S. President Donald Trump publicly criticized geopolitical betting, claiming “the world has become a casino,” but in reality, there have been continuous cases of “precise timing” trades, raising market concerns about insider information leaks and potential manipulation.

The latest case involves a U.S. soldier involved in the arrest of Venezuelan President Nicolás Maduro, who, hours before Trump announced the operation, bet over $33k on the prediction market Polymarket and ultimately made more than $400k in profit. He has now been arrested by U.S. authorities, and the case has been classified as a typical “insider trading in prediction markets.”

More attention is drawn to the “collective rush” in the commodities market. At multiple critical points, crude oil and stock index futures saw huge trades minutes to hours before Trump announced policy shifts (ceasefire, delaying strikes, etc.). For example:

· On April 7, around 3:45 p.m. Eastern Time, over 15 million barrels of crude oil futures (about $1.7 billion) were traded within two minutes, and three hours later, Trump announced a ceasefire, causing oil prices to plummet and the stock market to rebound;
· On March 23, 16 minutes before he announced delaying strikes on Iran, billions of dollars worth of crude oil and stock index futures had already been exchanged.

These trades, due to their “perfect timing,” have attracted regulatory attention. The U.S. Commodity Futures Trading Commission (CFTC) has launched an investigation under political pressure, with several lawmakers directly pointing out that these trades are “difficult to explain by luck.”

Despite the White House denying the existence of officials profiting from insider information and emphasizing that there is no evidence of government personnel violating regulations, warnings have been issued internally prohibiting the use of non-public information for trading.

Meanwhile, prediction markets and event-based derivatives are expanding rapidly, exacerbating information asymmetry issues. Data shows that geopolitical bets on Polymarket have surged to a weekly volume of $560 million, making it one of the fastest-growing sectors.

Overall, from on-chain prediction markets to traditional futures markets, the pattern of “policy signals → capital rush → sharp price fluctuations” keeps recurring. The decision-making pace of the Trump administration is increasingly being viewed by the market as a tradable “information source.”
