Warren Seeks Prediction-Market Safeguards After Staff Penalties

By Daniel Okafor

More than $170,000 in financial penalties and a three-year trading ban were imposed by the U.S. Commodity Futures Trading Commission (CFTC) and prediction-market platform Kalshi after a former White House staffer used advance knowledge of President Donald Trump’s remarks to bet in prediction markets.

The former staffer was responsible for operating Trump’s speech teleprompter. The case began after the person was found to have placed bets based on information about presidential remarks that had not been made public. The episode has prompted congressional demands for preventive rules governing the use of nonpublic presidential information.

Sen. Elizabeth Warren called for measures to prevent a repeat of a case involving White House staff trading on nonpublic information in prediction markets. Her focus was preventive: she argued that the White House needs safeguards before another government worker can turn privileged speech information into a market position.

CoinDesk reported on Nov. 10 that Warren and fellow Democratic Sen. Jeff Merkley sent a letter to White House Counsel Will Scharf, asking him to “detail specific steps to prevent insider trading in prediction markets.” The two lawmakers said the case raises serious concerns about the Trump administration’s ethics oversight system.

In their letter, the lawmakers said “the only public action taken by the White House so far was the distribution of a warning memo.” They criticized the White House for not putting substantive preventive measures in place and said stronger ethics rules were needed to stop staff from using inside information.

What does the White House need to change?

The request extends the enforcement question beyond the penalties already imposed. CFTC and Kalshi addressed misconduct that had already occurred; Warren and Merkley asked the White House to specify controls that would reduce the chance that staff could trade on unpublished presidential remarks.

For the White House, that means moving from a general warning to a documented ethics framework. For Kalshi and CFTC, the case keeps insider-information enforcement central to the credibility of prediction markets tied to political speech. The enforcement stakes are already concrete: more than $170,000 in financial penalties and a three-year trading prohibition for the person who exploited the information.

A warning memo communicates the risk, but it does not specify the process the White House will use to prevent recurrence. That gap is what Warren and Merkley asked Scharf to close with concrete steps and stronger ethics rules. The operational consequence is a shift from reacting after misconduct to establishing a rulebook before another trade occurs.

What could change in January?

Warren is poised to become chair of the Senate Banking Committee next January. In that position, she could use the committee to press the White House on prediction-market insider trading and conflicts of interest within the Trump administration, according to the report. The chairmanship would place her in a position to question whether the White House adopted the prevention steps requested in the letter.

Democrats are also pushing for tighter regulation through another route. Sen. Catherine Cortez Masto raised similar concerns, while Rep. Ro Khanna said trading in sports-related prediction markets should be banned outright. Their proposals range from conduct-based restrictions to a categorical prohibition on a class of contracts.

The Warren-Merkley letter also raised concerns about ties between the Trump family and the prediction-market industry. The lawmakers cited Donald Trump Jr.’s advisory role and his business relationship with a related company as a potential conflict of interest. That concern extends congressional scrutiny from a staffer’s misuse of information to the family’s commercial relationships with the sector.

The next deadline comes in January, when Warren is poised to take the Senate Banking Committee chair. Until then, the White House’s warning memo remains its only public response to the request for preventive safeguards.
