The Bizarre World of Prediction Markets

The Commodity Futures Trading Commission was established to oversee agricultural contracts like wheat and cotton. Over decades, the definition of «commodity» expanded to include interest rates, stock indices, and eventually Bitcoin. Today, you can legally trade futures on almost anything in America — except onions. The 1958 Onion Futures Act banned onion derivatives after two traders cornered the Chicago onion market in the 1950s, artificially inflating prices before crashing them entirely.

Prediction market platforms exploited this expanding definition. After successfully arguing in federal court that predicting an election is not «gaming,» they pushed further: if a presidential election is just an event, then a football game is also just an event. Kalshi began self-certifying sports contracts, offering bets on the Super Bowl, NBA, and Masters. This came as a shock to state regulators who had spent years building licensed, taxed sports betting regimes. Arizona responded with criminal charges. Ohio invoked the Statute of Anne, an 18th-century British law allowing third parties to sue to recover gambling losses.

The federal government's response has been striking. Under the new administration, the CFTC and Department of Justice went to court to block Arizona from enforcing its gambling laws against Kalshi. The federal government is now deploying legal resources to defend a tech platform's right to operate what states consider an unlicensed sportsbook. It may be worth noting that Donald Trump Jr. serves as a strategic adviser to both Kalshi and Poly Market, though the administration insists this is coincidental.

In traditional financial markets, trading on non-public material information results in federal prosecution. In prediction markets, proponents describe insider trading as a feature, not a bug. The logic: insiders bring valuable information that makes prices more accurate. Society benefits from better forecasts, even if the information came from a classified briefing.

Recent events test this theory. Last summer, a Poly Market user named «Rico Suave 666» made precise, lucrative bets on the exact timing of Middle Eastern military strikes. Israeli authorities arrested two men, including an army reservist, for allegedly using classified intelligence to place the bets. Shortly after the U.S. announced the capture of Nicolás Maduro, someone placed large, confident bets on Poly Market that he would be removed from office, walking away with hundreds of thousands. It's unclear who placed those bets, but they had better information than most of the U.S. Senate.

The reason insider trading is banned in stock markets is simple: if ordinary investors believe the game is rigged, they stop investing. Companies can't raise capital, factories don't get built, research doesn't get funded. The U.S. economy has succeeded because it built fair institutions. Prediction markets don't fund anything. They just move money from retail bettors to algorithms and people with security clearances. But if the public decides it's all rigged, distrust spreads beyond prediction markets to the entire financial system.
