A viral clip of White House Press Secretary Karoline Leavitt abruptly ending a briefing seconds before a key betting threshold has amplified concerns about insider trading in prediction markets. The incident comes as 30 Democrats introduced legislation to ban elected officials from placing political bets.
It might have started as a joke—but no one was laughing.

The 30-Second Exit
The controversy began on January 7 when Leavitt concluded her daily briefing at approximately 64 minutes and 30 seconds, just shy of the 65-minute mark that prediction market Kalshi had set as a betting threshold. At the time, the market showed a 98% probability that the briefing would exceed 65 minutes. Traders who bet against this outcome saw returns of up to 50x within seconds.
The clip, posted by X influencer PredictionMarketTrader, quickly went viral. The critics accused the White House of market manipulation. Democratic strategist Mike Nellis wrote, “We live in the dumbest f—ing timeline,” while others called for prediction markets to be banned outright.
However, the original poster later added that the tweet was intended as humor. “Guys, this is very obviously not insider trading—there was $3k traded on the market,” PredictionMarketTrader wrote on January 10. Kalshi confirmed that the total volume was just $3,400, with the largest position at $186, calling insider-trading claims “baseless.”

The Real Trigger: Maduro Capture Bet
While the briefing incident proved to be a false alarm, it amplified existing concerns stemming from a far more serious case. One Polymarket account wagered that Venezuelan President Nicolás Maduro would be removed from power by month’s end, netting $400,000 when US forces captured him last week on drug trafficking charges.
This bet triggered immediate legislative action. On January 10, Rep. Ritchie Torres (D-NY) introduced the “Public Integrity in Financial Prediction Markets Act of 2026,” backed by 30 Democrats, including former House Speaker Nancy Pelosi.
The bill would bar federal elected officials, political appointees, executive branch employees, and congressional staff from betting on government policy, government action, or political outcomes when they have access to material non-public information.

The Pelosi Irony
Pelosi’s co-sponsorship adds an ironic layer to the legislation. The former Speaker has long faced scrutiny over her husband, Paul Pelosi’s, stock trades, which have consistently outperformed the market. Since taking office in 1987, the Pelosi portfolio has returned an estimated 16,930%, compared with 2,300% for the Dow Jones Industrial Average over the same period.
The suspicion has spawned a cottage industry. A “Nancy Pelosi Stock Tracker” account on X has amassed over 1.3 million followers, with $1 billion invested alongside via fintech startup Autopilot that automatically mirrors her husband’s disclosed trades. There’s even an ETF with the ticker symbol “NANC.”
In one notable case, Paul Pelosi sold $500,000 worth of Visa shares in July 2024—two months before the DOJ filed an antitrust lawsuit against the company. A similar pattern emerged in 2022 when he sold Google shares one month before that company faced antitrust action.

Pelosi’s office has consistently stated that she “does not own any stocks” and has “no prior knowledge or subsequent involvement” in her husband’s transactions. When asked about banning congressional stock trading in 2021, she responded: “We are a free-market economy. They should be able to participate in that.”
Industry Implications
Prediction markets like Polymarket and Kalshi have surged in popularity since the 2024 election cycle, often leveraging cryptocurrency for transactions. The briefing episode, though ultimately trivial in scale, exposed a structural vulnerability: markets that allow betting on events directly under the control of individual actors create inherent manipulation risks.
Whether the Democratic bill gains Republican support remains unclear. Torres’ communications director said the congressman “encourages any and all members of Congress to join.” Given that President Trump’s son, Donald Trump Jr., reportedly holds a multi-million dollar investment in Polymarket, a bipartisan consensus may prove elusive.
For now, the prediction market industry faces its first serious regulatory challenge—sparked by a “satirical” tweet that everyone believed, precisely because it was entirely plausible.
