The prediction market platform Kalshi announced on Monday it has permanently banned former Republican Rep. George Santos and fined him $71,356 for allegedly using the app to trade on his own attendance at this year’s State of the Union address.

It’s the first ban of its kind on the platform, the company confirmed on Monday.

In the weeks leading up to President Donald Trump’s speech in February, Santos, who represented New York’s 3rd Congressional District from January 2023 until his expulsion from Congress later that same year, allegedly made more than $17,000 by betting on whether he would attend.

In the weeks leading up to the event, Santos “began making a series of public statements regarding his attendance at the event in an attempt to influence the price of Yes and No contracts, respectively. Some of these included false or misleading statements,” according to a Kalshi announcement of the disciplinary action, released Monday. Those actions violated the company’s rules on trading on non-public information, Kalshi said.

In one X post from days before Trump’s address, Santos said: “I’m going to be there for the State of Union in the gallery, guys.” On the day of the State of the Union, Santos posted he was watching from the airport.

Santos shot back at Kalshi on Monday in a post to X.

“Hey @Kalshi thanks for the lifetime ban from your gambling platform. Let’s see how much longer you guys are around for,” the former lawmaker wrote, ending the post with a “kiss mark” emoji.

Kalshi’s disciplinary action is not the first time Santos has drawn fire for the incident.

After Kalshi detected his trades and referred him to federal investigators, the Commodity Futures Trading Commission in July ordered Santos to pay $35,000 for trading on State of the Union attendance. The federal regulator also banned Santos from trading for three years. Santos at the time shared a statement from his lawyer saying he had settled without admitting to any of the CFTC’s findings.

In June, amid the federal investigation, Polymarket, a rival prediction market platform, ended its paid relationship with Santos, who had been working as an online influencer for the company.

Before Santos was sworn into office in 2023, doubts about his biography had emerged. His time in Congress was punctuated by a House Ethics Committee investigation that found “substantial evidence of wrongdoing.” He became the first member of the House to be expelled in more than 20 years.

Santos had also been sentenced to 87 months in prison for wire fraud and aggravated identity theft, though President Donald Trump commuted his sentence last fall.

Kalshi also announced settlements on Monday with three political candidates who traded on contracts related to their candidacies: a governor candidate in California, another gubernatorial hopeful in Maine, and a congressional candidate in North Carolina. All have to pay penalties and are banned from Kalshi for three years, but the company said all three complied with the investigations, unlike Santos.

While the candidates for California and Maine governor lost their races, Laurie Buckhout is the Republican nominee for the battleground North Carolina 1st Congressional District, where she faces Democratic incumbent Rep. Don Davis. Buckhout will have to pay a penalty of just under $2,600 for her trades.

“I bet on myself. Literally,” Buckhout said in a statement. “It was a dumb mistake, and as soon as I learned there was an issue, I worked to make it right. Safe to say my career as a Kalshi trader was short-lived.”

Oil prices extended gains Tuesday as traders mulled the threat of escalation, following the resumption of U.S.-Iran military strikes and more turmoil in the Strait of Hormuz.

A tanker was struck by three unknown projectiles while transiting Hormuz on Monday, according to an incident report from the the U.K. Maritime Trade Operations Centre.

The tanker was sailing in the southern shipping lane close to the Omani coast, the UKMTO said, adding that no casualties were reported.

Iran launched an attack on two American bases in Jordan on Monday in retaliation for the U.S. strike on its Larak Island. American forces targeted two Iranian rocket launchers on Larak Island on Sunday, reportedly killing three, saying that Tehran intended to launch rockets carrying sea mines into the Hormuz Strait.

The small island, located in the strait, has been a critical military and shipping control point for Iranian forces, helping them keep a firm grip on vessel traffic through one of the world’s most critical maritime routes.

Iranian President Masoud Pezeshkian told the Shanghai Cooperation Organisation Summit on Tuesday that Tehran would immediately reciprocate if Washington agreed to return to its commitments under the interim deal signed in June, according to the Iranian Student News Agency.

The back-and-forth hostilities marked the first time that the U.S. and Iran traded strikes in over a month.

While neither side appeared to be seeking a return to full-scale war, both signaled they were prepared to respond to further attacks. “We are going to hit them hard,” President Donald Trump told Fox News on Monday, saying that “there will be a response” to Iran’s attacks on U.S. military bases in the region.

Analysts largely view the U.S. strike on Larak Island as an attempt to break a deadlock rather than a shift in strategy. “By hitting the launchers rather than broader Iranian military infrastructure, the U.S. appears to be punishing a specific behaviour rather than, at least for now, broadening its war aims,” said Ali Vaez, deputy program director at International Crisis Group.

“It is enforcing the blockade,” said Jason Brodsky, policy director of United Against Nuclear Iran, adding that the Trump administration’s goal was to further degrade Tehran’s capabilities to mine the Strait of Hormuz, while focusing on economic coercive measures as the midterm elections approach.

Washington has ramped up pressure to squeeze Iran’s already-torn economy with “secondary sanctions” that punish nations and businesses buying Iranian crude oil. U.S. Treasury Secretary Scott Bessent said Monday, on the sidelines of the Group of 20 finance ministers gathering, that Iran was “lashing out kinetically” because the new sanctions were taking a toll on its economy.

Speaking from the Oval Office on Monday, Trump reportedly said Iran’s financial systems, armed forces, and governing body have been largely degraded. “It doesn’t mean we won’t smack them to see what happens,” the president said.

The war, now stretching into its seventh month, has disrupted global energy supplies and sent shock waves through global financial markets.

“This is fundamentally an endurance contest,” said Brodsky, as Trump has demonstrated an “unpredictability” that should concern the Iranians, and Tehran may lash out more aggressively militarily as the economic pressure mounts.

August has been a solid month for stocks, but investors hoping to stash some cash in the fall can still be paid well for using certificates of deposit. Savers are keeping an eye on the Federal Reserve as its Sept. 15-16 meeting approaches. Fed funds futures trading suggests a roughly 65% likelihood the central bank will raise its benchmark lending a quarter percentage point, to a range of 3.75% to 4%. Speaking in Jackson Hole, Wyoming late last week, Fed Chairman Kevin Warsh highlighted his worries about stubborn inflation . He noted that “while this summer’s [inflation] readings were better than expected, they do not tell me that underlying trends have meaningfully improved.” Indeed, the July reading of the personal consumption expenditures price index rose at an annual rate of 3.7%, topping the Dow Jones consensus by 0.1 percentage point, and far above the central bank’s 2% inflation target. While higher rates are unwelcome for borrowers, they’re a great development for savers who can capture higher yields on products such as certificates of deposit. Several banks, for example, continue to aggressively price their CDs and offer attractive yields as they compete for deposits. Latest increase Just last week, Sallie Mae lifted the annual percentage yield on its one-year CD by five basis points to 4.2%. The increase lifts Sallie Mae’s one-year CD rate some 25 basis points above the peer median APY of 3.95%, according to Vincent Caintic, analyst at BTIG. One basis point equals 1/100th of a percent, or 0.01%. Other financial services firms also continue to offer compelling rates on their one-year CDs. Popular Direct pays an APY of 4.25% on its 12-month CD, as of Monday afternoon, while CIBC touts a 4.15% yield. Savers can also find attractive rates if they’re willing to look outside the 12-month term. Synchrony Financial offers a 4.3% APY for a 16-month CD, while Marcus by Goldman Sachs has a similar rate on its 18-month instrument. Happen Bank has an 11-month CD with a 4.2% APY. If you’re thinking of getting into a CD, be sure to weigh your time horizon and liquidity needs. “Breaking” a CD before maturity carries a penalty of forfeited interest. Savers should also be aware of when their CD is about to expire, as their banks may automatically put them into a renewal CD at a lower rate.
