The most on-brand prediction market story of 2026 arrived this week, and Aaron Sorkin couldn't have written it. George Santos, the former congressman who went to prison on federal fraud charges before Trump commuted his sentence last year, is now under federal investigation for alleged insider trading on Kalshi. Take a moment to appreciate the man’s body of work. This is someone who claimed a Wall Street career at Goldman Sachs and Citigroup he never had, a Baruch College degree he never earned, and a portfolio of 13 rental properties that did not exist while he was actually living at his sister’s place. He said he sacrificed both knees as a volleyball star at a school he never attended. He claimed his mother died in the South Tower on 9/11, though immigration records show she was in Brazil at the time and passed away years later. The fabrications eventually became a 13-count federal indictment for wire fraud, money laundering, and theft of public funds, later expanded to 23 counts, with prosecutors describing a career built on relying on repeated dishonesty and deception to ascend to Congress and enrich himself. He was serving more than seven years when Trump commuted his sentence last year, and he walked after less than three months inside.
So the natural next move for a man who lied his way into Congress, into prison, and out of prison early was to find the one venue where deceiving the public for money is the literal mechanic of the game. Kalshi flagged it: Santos allegedly bet that he would not attend Trump’s State of the Union, posted “I’ll be in the gallery” on February 23, skipped the speech, and watched the odds break his way. Asked by NPR whether he even had a Kalshi account, Santos said, “I’m not saying yes, I’m not saying no.” He then offered that Kalshi’s co-founder is “a fellow Brazilian” he knows personally, and said he would call her to get to the bottom of it. A man under investigation for market manipulation announcing he will personally phone the exchange. We have not seen the results of that call. We assume it went great.
Now, to the markets.
Will Mamdani Open a City-Owned Grocery Store by June 30?
Current odds: 2%
This is a live Polymarket contract sitting inside a category that has traded over $51.8 million, asking whether NYC Mayor Zohran Mamdani opens a city-owned grocery store by June 30. The city-run grocery store was a signature campaign promise, and the market has now turned a policy pledge into a deadline bet with money on it. This is prediction markets doing the one thing traditional political coverage cannot: putting a number and a date on whether a politician actually does the specific thing they said they would do. Mamdani, the 34-year-old democratic socialist, won on a platform of higher taxes, rent freezes, and free public transit, and his November victory was priced at 93% by Polymarket before election day, a forecast so confident that Bitcoin dropped below $107K as traders reacted to it. The grocery store market is the sequel. The campaign is over. Now the crowd prices the follow-through.
TRADE: Nara Smith Confirmed Pregnant in 2026?
Current odds: 50% Yes
The crowd currently gives a 50% chance that TikTok cooking influencer Nara Smith gets confirmed pregnant in 2026, with about $77,000 traded on the question and resolution scheduled for December 31. Somewhere there is a person who looked at the entire universe of human events, the wars, the elections, the trillion-dollar companies, and decided their edge was the reproductive timeline of a woman who films herself making cereal from scratch. The genuinely funny part is the track record. Smith announced baby number four less than a year after publicly saying she was “absolutely done” having kids, having already done the same thing on a previous pregnancy. So the “No” holders are betting against a person whose entire brand is the surprise fourth act. There is a real concept buried in the joke: this is a market on a stranger’s family planning, priced to the penny, settled by press release. The attention economy has produced a futures contract on a pregnancy, and the order book is open.
The markets never sleep, but you should, ideally before you put your rent on a TikTok pregnancy. Go touch grass, or at least bet on whether someone else will.
Have a great weekend and see you Monday with the Opening Bell!
