Insider trading allegations during the second Trump administration

A number of financial analysts have identified significant signs of insider trading in the U.S. government during the second presidency of Donald Trump. Allegations of insider trading have focused on U.S. officials, anonymous accounts on prediction markets with suspiciously high win rates, as well as Trump and his family.

While previous presidents have employed blind trusts or otherwise refrained from trading while in office, Trump has made billions of dollars from security trades since 2025. He has bought stocks of multiple companies that have been impacted by his decisions as president, and publicly promoted companies whose stocks he had bought. Trump said in June 2026 that his children have had "inside information" while trading stocks impacted by his presidential actions, and denied any ilegal conduct. United States conflict-of-interest laws do not prohibit the president of the United States from "participating personally and substantially in a particular Government matter that will affect his own financial interests".

Prediction market platforms soared in popularity after Trump was elected for the second time, with many well-timed trades done mostly by newly-created and single-purpose accounts correctly predicting actions by the executive branch of the United States shortly before they happened. Accounts suspected of insider trading have on multiple occasions bet on events such as the 2026 Iran War and tariffs decisions of Trump.
