Forecast Trend Report by Period

Sen. Elizabeth Warren called for measures to prevent a repeat of a case involving White House staff trading on nonpublic information in prediction markets.

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

The controversy began after a former staffer responsible for President Donald Trump's speech teleprompter was found to have placed bets in prediction markets using advance knowledge of the president's remarks. The staffer was hit with more than $170,000 in financial penalties by the Commodity Futures Trading Commission and prediction-market platform Kalshi, and was barred from trading for three years.

Warren and other lawmakers criticized the White House for failing to implement substantive measures to prevent a recurrence after the incident. In the letter, they said the only public action taken by the White House so far was the distribution of a warning memo. They argued that stronger ethics rules are needed to stop staff from using inside information.

They also raised concerns about ties between the Trump family and the prediction-market industry. In particular, they cited Donald Trump Jr.'s advisory role and business relationship with a related company, saying it could create a conflict of interest.

Democrats are also pushing for tighter regulation of prediction markets. Sen. Catherine Cortez Masto raised similar concerns, while Rep. Ro Khanna said trading in sports-related prediction markets should be banned outright.

Warren is poised to become chair of the Senate Banking Committee next January. That could make prediction-market insider trading and potential conflicts of interest in the Trump administration major targets of congressional oversight.
