Kalshi Probes Suspicious Trades Before Katie Zacharia Was Named Press Secretary
Key Points
- At least three Kalshi trades backed Zacharia while she was priced around a 1% chance of becoming White House press secretary, including a $19 position that could return nearly $1,900.
- There is no public finding that any trader possessed or used inside information, and Kalshi has not disclosed the identities behind the trades.
- The investigation comes weeks after the CFTC punished a former White House employee for using advance access to presidential speeches to profit on prediction markets.
- Any evidence of government insiders trading on advance appointment information would add fuel to existing congressional efforts to restrict political insiders from trading event contracts.
Kalshi Investigates Katie Zacharia Press Secretary Prediction Market Trades
Kalshi is investigating at least three unusually well-timed trades that backed Katie Zacharia to become President Donald Trump’s next White House press secretary before her selection became public.
The Wall Street Journal reported that Zacharia had been trading at roughly a 1% probability before the appointment. One position costing about $19 could return nearly $1,900, while two other small trades were positioned for payouts worth several thousand dollars more.
The timing was enough for Kalshi to open a review, but the public evidence currently goes no further. There has been no finding that the traders possessed nonpublic information, no trader has been publicly identified, and Kalshi has not announced any disciplinary action.
Kalshi’s Rules Already Prohibit Trading on Nonpublic Information
Kalshi’s published rules for its next White House press secretary market prohibit trading by anyone holding material, nonpublic information related to the outcome. Candidates listed in the market are also prohibited from trading the contract.
Kalshi also requires customers to complete identity verification, meaning publicly pseudonymous trades can still be connected to verified account holders during a compliance investigation. That gives the exchange a path to examine who placed the trades, their trading history and potentially whether their employment or other relationships created access to sensitive information.
The Zacharia investigation also arrives after Kalshi spent much of 2026 strengthening those controls. The company announced new political screening measures in March and later added risk scoring and employment verification for markets with elevated insider trading concerns.
The CFTC Already Has a White House Insider Trading Case on the Books
The timing is especially sensitive because federal regulators dealt with a remarkably similar information advantage only weeks ago.
On August 28, the Commodity Futures Trading Commission announced an enforcement order against Gabriel Perez, a former White House teleprompter operator who had advance access to presidential speeches. The CFTC found that Perez used material, nonpublic information from those speeches to trade presidential mention contracts between December 2025 and February 2026.
Perez was ordered to disgorge $107,539.02 in trading profits and pay a $65,000 civil penalty. He also received a three-year trading ban.
That case established a concrete precedent for the regulatory risk surrounding government information markets. White House appointments create a similar structural vulnerability: the final decision can be known by a relatively small group of people before the public announcement moves the market.
Washington Is Already Moving Toward Tougher Insider Rules
The investigation also lands in the middle of an active congressional debate over who should be allowed to trade political event contracts.
In March, a bipartisan group of senators introduced the Public Integrity in Financial Prediction Markets Act of 2026, legislation aimed at preventing federal officials and government employees from trading contracts using information obtained through their official duties.
“No one should be profiting off the information and knowledge gained as a public servant, period,” Sen. Elissa Slotkin said in announcing the bill.
A confirmed second case involving advance White House information would give supporters of those restrictions a much stronger example to point toward. Even without a finding of misconduct in the Zacharia trades, the investigation illustrates why government appointment markets present unusually concentrated information risks.
Why This Matters For Bettors
For ordinary traders, the immediate concern is market fairness. In cases of insider trading, it is bettors that ultimately bear the Cost of Information Asymmetry.
At a 1% price, participants were effectively assigning Zacharia almost no chance of getting the job. A trader with definitive advance knowledge could instead purchase contracts at extremely favorable prices from counterparties who were still pricing genuine uncertainty.
That kind of information advantage can be particularly damaging in political contracts involving appointments, speeches and government decisions. The result may already be fixed internally while the market continues trading as though everyone is still trying to predict what will happen.
That changes the quality of the market itself. Good research, political expertise and faster analysis can all produce legitimate edges. Competing against someone who already knows the answer creates a fundamentally different risk.
What Happens Next
Kalshi has not publicly identified the traders or disclosed what triggered its investigation. The company says its normal surveillance process can include freezing flagged accounts, examining funding and trading histories and reporting confirmed violations to the CFTC.
The next significant development will be whether Kalshi closes the review without action, disciplines one or more accounts or refers evidence to federal regulators.
If the investigation establishes that someone with advance government information traded on Zacharia’s appointment, congressional proposals restricting political insiders would suddenly have another highly specific White House example behind them.
