Warren Puts Pressure on the White House After Teleprompter Bets
Warren is asking the White House what steps have been taken after bets on prediction markets that may have been based on nonpublic information. The case is increasing pressure on oversight and market integrity in the U.S.

Key Takeaways
- Elizabeth Warren is asking the White House what steps have been taken after the insider trading case involving a former teleprompter staffer for Donald Trump.
- Warren and Jeff Merkley say the bets on prediction markets may have been based on nonpublic information.
- The letter fits into broader Democratic plans to put more focus on insider trading, market integrity, and oversight of prediction markets.
U.S. Senator Elizabeth Warren has asked the White House what it is doing to prevent a repeat of the insider trading case involving a former teleprompter staffer for President Donald Trump. The Democrat from Massachusetts wants White House counsel Will Scharf to explain what steps have been taken after the bets on prediction markets that, according to the senators, were based on nonpublic information.
Warren Turns to the White House
Warren and Senator Jeff Merkley sent a letter on Tuesday in which they describe the former staffer's transactions as part of a longer series of troubling incidents under the Trump administration. According to them, the case raises questions about what other unethical activities may be taking place under White House oversight.
The timing is politically important. Warren is expected to become chair of the Senate Banking Committee in January, which would give her more influence over financial oversight. In that role, she could put more pressure in the coming months on issues like insider trading, prediction markets, and the government's role in them.
More Pressure on Prediction Markets
Warren has long been critical of prediction markets, crypto, and Trump's involvement in both. In her letter, she says the White House since Trump's inauguration appears to have become tangled in a culture of corruption and greed, with personal financial interests put ahead of the public interest.
For European crypto followers, this matters because the debate shows how closely prediction markets and related crypto services can be watched in the U.S. The CFTC has already taken tougher action against insider trading in 2026, while platforms in this market are more often under a microscope because of suspicions of misuse of nonpublic information. That fits into a broader series of legal and political conflicts around event contracts, such as the case in which the CFTC and Kalshi are directly at odds over the scope of oversight on prediction markets.
Democrats Prepare New Investigations
The letter also fits into the broader political preparation for the next congressional term. Democrats are gearing up for their new majorities in Congress and are expected to give more attention to alleged self-enrichment and corporate influence around the Trump administration.
That does not mean new measures are already set, but it does mean insider trading and market integrity are likely to move higher on the agenda. For the crypto sector, that could once again lead to more debate over how prediction markets should be regulated and what role regulators should play.
