The Department of Justice has opened an investigation into former Rep. George Santos over alleged insider-style trading on the prediction market Kalshi, this time centered on bets tied to whether he would attend President Trump's State of the Union address in February, the New York Post reported.
The scheme, if confirmed, is brazen in its simplicity. Santos publicly told followers he planned to attend the speech. He allegedly placed bets that he would not. Then he skipped the event entirely, posting from an airport that his absence was unplanned, while the market moved in his favor.
The probe marks the latest legal headache for a former congressman who already served time in federal prison for wire fraud and aggravated identity theft. It also raises sharp questions about how prediction markets can be manipulated by the very public figures whose actions set the odds.
The day before Trump's Feb. 24 address, Santos posted a video on X announcing his plans.
"I'm going to be there for the State of Union in the gallery, guys," Santos said.
At the time, Newsmax reported that Kalshi odds of Santos attending were near 75 percent. That number reflected public confidence, Santos had repeatedly discussed his intention to show up.
Then came the speech. Santos was nowhere near the Capitol gallery. Minutes into Trump's address, he posted again on X:
"Watching SOTU from an airport tv was not part of the plan! FML,"
Moments after that post, the Kalshi market odds on Santos' attendance collapsed. Anyone holding a position that Santos would skip the event stood to collect.
Sources familiar with the trades told NPR that Santos had allegedly bet on Kalshi that he would not attend, the opposite of what he told the public. Those sources alleged he sought to bilk "tens of thousands of dollars" by misleading followers about his plans. The exact amount he wagered and the precise profit remain unclear.
Kalshi eventually flagged Santos' trades as suspicious, froze his account, and referred the matter to both the Commodity Futures Trading Commission and the DOJ, AP News reported, citing a source with knowledge of the referral. The CFTC has said it is targeting insider trading in prediction markets, a growing concern as platforms like Kalshi expand into political event contracts.
The DOJ has not publicly confirmed the investigation. The Post reached out to the department for comment.
Santos, for his part, offered a mix of denial and deflection. When NPR asked whether he had a Kalshi account, Santos replied:
"I'm not saying yes, I'm not saying no."
Told about the investigation, he said it was "news to [him]." He also claimed he personally knows Kalshi co-founder Luana Lopes Lara and said he would call her to ask about it. A source told NPR that Santos and Lara have never interacted.
On his podcast, Santos struck a different tone, as the Washington Times noted. "I guess people lost money. Some people made unexpected money. That's to show you how fragile these markets are," he said, a remark that reads less like innocence and more like a shrug.
Santos is no stranger to federal courtrooms. He was sentenced to 87 months in prison for wire fraud and aggravated identity theft, crimes committed during his brief, scandal-ridden tenure in Congress. He served less than three months at FCI Fairton, a medium-security facility in Fairfield Township, New Jersey, before President Trump commuted his sentence last October.
Trump said at the time that Santos had been in solitary confinement for long stretches and, "by all accounts, has been horribly mistreated," Just The News reported.
The commutation drew scrutiny but was within the president's constitutional authority. What it did not do, and could not do, was immunize Santos from future legal exposure. If the DOJ determines he manipulated a prediction market using information only he controlled, the commutation becomes a footnote to a fresh set of problems.
Federal investigations into current and former political figures have become a recurring feature of the current enforcement landscape. The DOJ has probed other high-profile lawmakers in recent months across party lines, and the department's willingness to pursue cases regardless of political affiliation is a test of its credibility.
The Santos case highlights a vulnerability that prediction market critics have warned about since these platforms gained mainstream traction. When a public figure can move a market simply by announcing plans, and then profit by doing the opposite, the incentive structure invites abuse.
Kalshi has taken some steps. In April, the platform suspended three congressional hopefuls, a Democrat, a Republican, and an Independent, who bet on themselves in their respective races. That same month, the White House warned staff against insider trading after several mystery gamblers made thousands of dollars in blitz trades on Iran War dealings.
A bipartisan coalition of Republican lawmakers and two Democrats is now pushing legislation to ban representatives, their families, and their staffers from participating in prediction markets and trading stocks. The effort mirrors longstanding concerns about congressional stock trading, but the prediction market angle adds a new dimension. A lawmaker, or former lawmaker, doesn't need classified briefings to move a political event market. He just needs a social media account and the willingness to lie about his own schedule.
The DOJ's broader fraud crackdown under Acting Attorney General Todd Blanche has put public-corruption and financial manipulation cases front and center. Whether the Santos matter rises to a prosecutable offense depends on the specific statutes implicated, details that remain unclear from current reporting.
The most damaging element for Santos may not be the trades themselves but the pattern they fit. This is a man who fabricated large portions of his biography to win a congressional seat, pleaded guilty to federal fraud charges, and now stands accused of deceiving the public again, this time to rig a bet worth tens of thousands of dollars.
His response to NPR, "I'm not saying yes, I'm not saying no", is the answer of someone who has learned that ambiguity buys time. But ambiguity does not buy credibility, and Santos has none left to spend.
The Washington Examiner reported that the investigation centers squarely on whether Santos profited by publicly suggesting he would attend while allegedly betting that he would not. If prosecutors can establish that Santos controlled the outcome and traded on that knowledge, the case becomes a textbook example of market manipulation, dressed up in the new clothes of prediction market politics.
Conservatives who support prediction markets as a tool for price discovery and free expression should be the first to demand that bad actors face consequences. Markets work when participants trust the information environment. A convicted fraudster allegedly gaming a political event contract undermines the case for the very platforms many on the right have championed.
The broader pattern of lawmakers and former officeholders facing serious criminal allegations should concern voters of every stripe. Public office, and the residual influence it carries, is not supposed to be a launchpad for personal enrichment schemes.
Several open questions remain. The DOJ has not confirmed the probe on the record. The exact laws or regulations Santos may have violated are not yet public. And the amount he allegedly wagered and won has not been pinned down beyond the "tens of thousands" figure cited by sources.
What is clear is that Kalshi saw enough to freeze the account and send the file to two federal agencies. That is not the action of a platform shrugging off a borderline case.
George Santos told the public he would be in the gallery. He told the market, allegedly, that he would not. Only one of those statements could be true, and the DOJ now wants to know which one he believed when he placed the bet.
A man who already went to prison for fraud should have known better than to treat a prediction market like a personal ATM. Then again, knowing better has never been Santos' strong suit.
