What do you get when you cross $5 million with a young man with access to gambling apps? Brendan Sorsby is just one victim of prediction markets, which are corrupt markets, bad for individuals, and a threat to national security that no ballroom can fix.
"A hairdryer was allegedly used to rig Polymarket bets on the weather at Charles de Gaulle airport in Paris, according to a report by The Telegraph. French authorities note that the official temperature readings at the airport spiked twice in the past month, reaching levels much higher than expected. On both occasions, gamblers on Polymarket appear to have walked away with thousands upon thousands of dollars by betting on those temperature fluctuations.
The gambling site relies on readings from temperature sensors, and the one at Charles de Gaulle airport is on a public road. This makes it easy to access. The operating theory is that someone snuck in and used a battery-powered hairdryer to bring the recorded temperature up well beyond the actual heat outside.
Meanwhile, the Polymarket page indicated less than a one percent chance of the airport exceeding a particular temperature. Successful bets on these fluctuations netted an unknown user around $34,000."
Polymarket Exposes Vulnerabilities in Event Verification Process

"John Pederson, 33, couldn’t work. The former Outback Steakhouse line cook was recovering from a car crash and running out of money. Kalshi, the prediction market, promised a quick way to fix that. He took out a variable-interest loan and started betting.
At first, it worked. Pederson turned about $2,000 into close to $8,000 by betting on daily snowfall totals in Detroit, where he lives. He parlayed that into $41,000 by trading on sports, using a strategy he developed with the help of AI, according to a Wall Street Journal review of his account records.
Then he placed his most audacious bet yet: All $41,000 that a celebrity would say a particular word on TV. He lost it all.
Pederson isn’t alone in walking away empty-handed from the bet-on-anything markets, which cover sports, celebrities, news and more.
Kalshi and its competitor Polymarket advertise themselves as life-changing tools for regular people—implying everyone has a fair chance to score. “I was about to be unable to pay my rent, but I got two years of rent through Kalshi’s predictions,” gushed one woman in a Kalshi ad on TikTok.
But for most users the reality is nothing like that.
Instead, casual traders are bleeding cash while a small number of sophisticated pros—including trading firms with access to vast streams of data—eat their lunch, according to a Journal analysis of platform data and interviews with traders.
On Polymarket, the Journal found, 67% of profits go to just 0.1% of accounts. That means less than 2,000 accounts netted a total of nearly half a billion dollars. The Journal analyzed 1.6 million Polymarket accounts that have traded since November 2022. There are at least 2.3 million total accounts on the site."
