1. Two Senators Demand Answers From a White House Lawyer
Senators Elizabeth Warren and Jeff Merkley wrote to White House lawyer Will Scharf in a letter made public on Tuesday, November 10, asking what the administration is doing to prevent another Kalshi insider trading episode like the one involving a former teleprompter operator who bet on what President Donald Trump would say. They argue the White House has taken "no meaningful action."
Warren, a Massachusetts Democrat, and Merkley, an Oregon Democrat, described the wagers as "another in a long series of disturbing incidents" under the current president. Their letter also voices concern about other unethical activity that may be taking place under Scharf's supervision.
The inquiry carries more weight than a routine oversight letter because of who sent it. Warren is expected to take over as chair of the Senate Banking Committee in January, a position that will give her considerably more authority over financial matters. She has spent years scrutinizing prediction markets, cryptocurrency and the president's involvement in both.
2. What the Letter Asks and Alleges
At its core, the document is a request for an accounting. The senators want Scharf to explain what steps are being taken so that people who work in the White House cannot profit from information they obtain through their jobs by placing bets on event contracts.
The letter couples that request with a broad accusation. It argues that the White House has become defined by "a culture of corruption and greed that has placed personal financial interests ahead of the public interest." The teleprompter case, in the senators' telling, is a symptom of that culture and not an isolated lapse by one employee.
They also draw attention to how little the administration appears to have done since the bets became known. According to the letter, the only step the White House is publicly known to have taken on employee ethics in prediction markets was "circulating a warning memo, which is unlikely to counteract a broader cultural attitude of lawlessness." A memo reminds staff of rules; it does not, on its own, create monitoring, pre-clearance requirements or penalties, which are the tools institutions normally use to police trading by people with access to sensitive information.
Scharf is the natural recipient of such a demand. The senators address him as the official under whose supervision the conduct occurred, and their expressed worry about other unethical activity on his watch suggests they regard the teleprompter bets as a reason to look more widely at how staff conduct is overseen, not as a closed matter.
3. What Was the Kalshi Insider Trading Case?
The case involved a former White House employee who ran the president's teleprompter and placed prediction market bets on what he knew the president would say. The wagers came to light several months ago, and the Commodity Futures Trading Commission (CFTC) brought an enforcement action against the former staffer.
Kalshi is the prediction market platform named in connection with the matter. The resolution included a payment of more than $170,000 and a three-year trading ban. The former staffer had been disciplined for trading on what he knew the president was going to say.
The episode stands out as one of the first high-profile insider-trading cases in the fast-growing prediction market sector. The role at the center of it explains why. A teleprompter operator sees the text of a speech before it is delivered. Prediction markets list contracts on whether a public figure will say a particular word or phrase, or address a particular subject, during a scheduled appearance. Someone who has read the script in advance is not forecasting the outcome of such a contract. He already knows it.
The CFTC is the federal agency that oversees derivatives markets in the United States, including the event contracts offered by regulated prediction market platforms. Its involvement signals that regulators regard trading on non-public information in these markets as a matter for enforcement, in the same way that trading on confidential information is treated in other markets.
4. Why the Senators Say Enforcement Was Not Enough
Warren and Merkley do not dispute that the regulator acted. Their complaint is directed at the employer. The case, they wrote, "should have been a wake-up call to the entire administration to enforce stronger ethics policies." Instead, they say, the White House has taken "no meaningful action."
The distinction between punishing one person and changing an institution is central to their argument. An enforcement action addresses conduct after it has happened and after it has been detected. It does little to stop the next employee with access to a draft speech, an unannounced decision or a private schedule from making the same calculation. Preventing a repeat depends on the rules an employer sets for its own staff and on whether those rules are actively enforced.
That is why the senators question whether the CFTC's action was sufficient by itself. In their view, an administration serious about the problem would have responded with visible and enforceable ethics policies. A cautionary memo, as they see it, falls well short of that standard, particularly in a workplace where many employees routinely handle information that could decide the outcome of a contract.
5. How Inside Knowledge Distorts Event Contracts
Prediction markets let users buy and sell contracts tied to the outcome of real-world events, with prices that move as traders revise their views of how likely each outcome is. Supporters argue that those prices aggregate information efficiently and can be more accurate than polls or expert forecasts. The sector has expanded quickly, and the range of events on which contracts are offered has widened along with it.
That growth has brought a problem familiar from securities markets. When a contract depends on what a specific person will say or do, anyone close to that person holds an advantage that other participants cannot match. A trader on the other side of the bet is effectively wagering against someone who has seen the answer. If such trading becomes common, ordinary participants have less reason to trust that the market is fair, and the prices themselves become less a measure of collective judgment than a reflection of who has access.
Government employees present a particular version of this risk. People who work in and around the presidency see speeches, announcements and decisions before the public does. Contracts built around presidential remarks or government actions therefore create a direct opportunity for staff to convert their access into profit, which is the concern at the heart of the senators' letter.
The remedies used elsewhere in finance are well established. Firms that handle market-moving information commonly restrict what their employees may trade, require approval before trades are placed and review activity afterward. The senators' criticism implies that comparable controls have not been applied to White House staff and event contracts, leaving a warning memo as the main line of defense.
6. The Trump Family's Ties to the Industry
Warren has been a consistent critic of the president's connections to both cryptocurrency and event contracts, and the letter extends that criticism to his relatives. It says the president's family has become more entangled with the prediction market industry.
The senators single out Donald Trump Jr. in particular, citing his advisory work and his business connections to prediction markets. Their point is that the question of who benefits from these platforms reaches beyond a single former staffer. When members of the president's family have commercial relationships with companies in a sector, and people employed by the president have used inside knowledge to trade in that same sector, lawmakers see grounds to ask how seriously conflicts of interest are being managed.
The letter does not allege that the Trump family was involved in the teleprompter operator's bets. It presents the family's business ties as context for why the senators believe the administration has little incentive to tighten its own rules.
7. Other Democrats Are Raising Similar Concerns
Warren and Merkley are not acting alone. Senator Catherine Cortez Masto, also a Democrat, raised similar concerns on Monday, November 9, a day before their letter became public.
In the House, Representative Ro Khanna of California went further on Tuesday, calling for a full ban on sports-related prediction markets. Sports contracts are a distinct issue from bets on political speech, but the proposal shows how the debate over the sector is broadening. Lawmakers are no longer asking only whether insiders are abusing these markets; some are asking whether entire categories of contracts should be permitted at all.
Taken together, the statements suggest that prediction markets are becoming a regular target of Democratic oversight, with criticism ranging from the integrity of individual contracts to the scope of what the platforms are allowed to offer.
8. What Happens Next
The timing of the letter is tied to a change in power. Congress is in the waning weeks of its session, and Democrats are preparing to take over the majorities in both the Senate and the House. Letters such as this one indicate the subjects they are likely to pursue once they hold the committee gavels.
For Warren, the shift is specific. She is expected to assume the chairmanship of the Senate Banking Committee in January. A committee chair can do far more than a member of the minority: set hearing agendas, call witnesses and direct the committee's investigative attention. Questions that today arrive as a letter could, after January, be put to officials and company executives in a hearing room.
The immediate question is whether Scharf answers, and what the White House says it has done beyond the warning memo the senators describe. For prediction market operators, the letter is a signal that insider trading safeguards, and the industry's relationships with politically connected figures, are set to draw closer attention from the lawmakers who will soon control the committees that oversee them.
