Kalshi's $3M JFK Hedge Went to Zero. The Industry Barely Noticed

NEXTPredict paid Kalshi $12,000 for event-cancellation contracts that could have returned roughly $3 million. The trade expired worthless on October 21 — and the conference's co-founder couldn't have been happier about it.

"We ended up losing that trade yesterday, right?" NEXTPredict co-founder Pierre Lindh told the "Hedging the Unhedgeable" panel on October 22. "And I can only say I'm very happy that we lost that trade, because that means we're all here today."

The contracts would have paid out if more than half of scheduled arrivals at New York's JFK airport had been cancelled the day before the event. NEXTPredict held its summit at Convene Hudson Yards on October 22 and 23, drawing more than 2,000 attendees, 180 speakers and participants from 47 countries, less than two weeks before the U.S. midterms.

The failed hedge illustrated a serious point. Traditional event insurance covers outright cancellation, but "most of these type of force majeure situations won't cancel the event. It will severely damage the event," Lindh explained. Prediction markets fill that gap — a contract pays out on damage, not just disaster.

Joe Grubb, head of business development at Susquehanna, confirmed the quant firm took the other side and modeled the risk in-house within a day or two. "It's sort of in our DNA at Susquehanna to price strange things," he said.

Who is actually using these contracts?

Small businesses, according to Kalshi. Nicolas Hull, the exchange's director of business development, said a New York bar used Kalshi to cover a Knicks playoff promotion. Any contract certified with the Commodity Futures Trading Commission and tied to a verifiable data source can go live, he said: "We can list almost anything on our exchange."

Robinhood sees the same broadening. "When I started doing this two years ago, it was about elections," JB Mackenzie, the brokerage's vice president and general manager for futures and prediction markets, told CNBC's Contessa Brewer. "Then it transformed into politics and sports, and now it's moving into economics and financials."

Sports remains Robinhood's biggest category, Mackenzie said. But contracts on Bitcoin, crude oil and gold are the fastest-growing ones. His explanation: "The simplicity of a probability is much more consumable for customers."

What does the midterms test actually prove?

Former NBC News political director Chuck Todd moderated the "Who Calls the Midterms" panel and came out closer to a believer than he went in. "This is my argument of why I'm bullish on prediction markets for the future of journalism and that it should be this, in its own way, a fact checker," Todd said. "With money being involved, there's more incentive to get it right."

He argued that prediction markets have effectively replaced exit polls on election night, while defending polling itself. "You can still do a good poll. It just costs a lot," he said.

His panelists pushed back. "Speed is not necessarily the same as accuracy," said Columbia University professor Rajiv Sethi. PredictIt CEO John Phillips offered the sharper warning: "It's called wisdom of crowds, not wisdom of whales."

Days later, that caution looked justified. Before Brazil's presidential runoff, Polymarket gave Luiz Inácio Lula da Silva only about a 20% chance of beating Flávio Bolsonaro, as Decrypt reported. Lula won a fourth term. Experts blamed Brazil's ban on prediction markets, which left the odds to traders outside the country — a structural blind spot, not a pricing failure.

How does regulation catch up?

Polymarket's Bailey Springer, who handles regulatory strategy outside the U.S., said regulators in global financial hubs increasingly accept that "prediction markets aren't going away" and serve real investment and hedging uses. Her framing was direct: "At Polymarket, our position is that these are derivatives and should be regulated as such."

Speed was the other running theme. On the "Race to Zero Latency" panel, Farokh Sarmad, president and co-founder of Decrypt Media, argued retail traders lose the news race by default. "By the time you open Polymarket or Kalshi or Myriad or all the other prediction markets, you're usually a little too late," he said.

His answer is collapsing the gap between reading and trading, which Decrypt is attempting with its Solana-based Information Exchange. "The best way to reduce that latency is to be able to consume it and trade it directly on the same platform," Sarmad said, adding that "everything has to move on chain" for any of it to work.

Institutional interest ran through the program too, with Morgan Stanley leading sessions on the second day.

Lindh sees the industry's next fight already forming: "I think the next step will be the comparison between prediction markets and insurance."

With the midterms now the sector's largest live stress test, exchanges and regulators alike will be measuring crowd prices against poll-based forecasts — and the results will shape the debate over whether these contracts get treated as financial derivatives or something else entirely.
