Throughout Donald Trump's second term, a recurring pattern has emerged in US financial markets: large volumes of trades are placed just minutes or hours before the president makes major market-moving announcements. A data analysis by BBC World News has matched trade volume spikes to Trump's social media posts and media interviews, raising serious questions about whether insiders are acting on privileged information.
Oil markets and the Iran announcements
One of the clearest examples involves oil markets and Trump's statements about the US-Israel conflict with Iran. In a phone interview with CBS News, Trump described the war as "very complete, pretty much." The CBS reporter posted about the interview on X at 15:16 Eastern Time (19:16 GMT) — the moment the public first learned of the remarks. However, market data shows a massive surge of bets on falling oil prices had already occurred at 18:29 GMT, a full 47 minutes before that post. Oil prices subsequently plunged by around 25% as traders sold following Trump's statement.
A similar pattern appeared on 23 March, when Trump posted on Truth Social that Washington had held "VERY GOOD AND PRODUCTIVE CONVERSATIONS" with Tehran toward a "COMPLETE AND TOTAL RESOLUTION" to hostilities. Unusually high bets on the US oil price were recorded 14 minutes before that post went live. "The trades appeared 'abnormal, for sure,'" one oil analyst told the BBC at the time.
The tariff pause and stock market surge
The BBC analysis also examined trading activity around Trump's sweeping tariff announcements. On 2 April — dubbed Liberation Day — Trump unveiled tariffs on goods from virtually every country. A week later, he announced a 90-day pause on those levies for all nations except China. On the day of the pause announcement, contracts for a fund tracking the S&P 500 jumped to over 10,000 per minute just after 18:00 BST, compared to just hundreds earlier in the day. Some individual traders placed bets worth more than $2 million on the stock market rising — before the announcement was made public.
Insider trading allegations and official silence
The findings have drawn sharp reactions from US lawmakers. Several senior Democrats in the Senate wrote to the Securities and Exchange Commission urging it to investigate whether Trump's announcements had "enriched administration insiders and friends at the expense of the American public." The SEC declined to comment when asked by the BBC whether it had opened any inquiry. The White House did not respond to the BBC's request for comment.
Expert opinion on the trading patterns is divided. Some analysts say the activity "bears the hallmarks of illegal insider trading, whereby bets are made by people based on information that is not available to the general public." Others offer a less alarming interpretation: that "some traders have become more adept at anticipating the president's interventions," making apparent pre-announcement moves a product of informed guesswork rather than illicit tip-offs.
Prediction markets under scrutiny
Adding another dimension to the story, Donald Trump Jr. holds roles at two blockchain-powered prediction platforms — Polymarket and Kalshi — both of which allow users to speculate on events ranging from weather and baseball to US foreign policy. Trump Jr. is an investor in Polymarket and sits on its advisory board, and acts as a strategic advisor to Kalshi. Neither platform has been accused of wrongdoing, but their connection to the president's son has drawn additional scrutiny given the broader trading concerns.
The BBC said it examined trade volume data across financial markets and matched the figures to Trump's significant public statements. No charges have been filed and no formal investigation has been confirmed by regulators.
