Kalshi Launches Midterms Hub As Prediction Markets Keep Growing
Some people start the morning with a weather app. Others reach straight for the group chat. A growing number of Americans now start the day a third way: pulling up the live odds on their local House race.
Kalshi just made that habit a lot easier to keep.
What Kalshi Just Launched
On July 22, Kalshi rolled out its new “Midterms Hub,” a single page pulling together live prices for Senate, House and Governor races, polling averages from VoteHub, campaign fundraising numbers from the Federal Election Commission, and news coverage of each contest. It’s built as a one-stop page for voters, journalists, campaign staff and researchers, not just regular traders.
Kalshi says roughly three out of four visitors never place a trade. They come to check the numbers and move on, which says a lot: the company increasingly sees itself less as a trading app and more as a source people check the way they’d check a scoreboard.
CEO Tarek Mansour, a former Citadel trader and MIT graduate, framed the appeal in blunt terms: the prices, he said, reflect “real money, not rhetoric.” The hub also arrives right after Kalshi introduced its “American Power Index” in May, a running score of which political party is gaining ground.
Prediction Markets, Explained Simply
If none of this is familiar yet, here’s the short version: On a prediction market, people buy and sell contracts tied to a real-world outcome: who wins a Senate seat, whether a storm hits a city, whether a company beats its earnings target. A contract pays off if the event happens and pays nothing if it doesn’t, and its price shifts as new information comes in, much like a stock price reacts to news.
That price works like a running forecast. Instead of asking a sample of people what they expect, the way a poll does, a market shows what a smaller group is willing to put real money behind. Supporters argue that makes the numbers harder to fake. Skeptics counter that heavy trading, or someone with early information, can also push prices around.
Kalshi and Polymarket: The Two Names Everyone Mentions
Two platforms dominate this space: Kalshi and Polymarket.
Both operate under the Commodity Futures Trading Commission, the federal agency that also oversees derivatives markets, and both list contracts on everything from elections to sports to interest rate decisions. Kalshi has leaned hard into U.S. politics lately, while Polymarket built its name covering global events at massive scale: its contract on the World Cup final alone crossed $4 billion in trading before the match even kicked off, a number we broke down in our recent coverage of prediction markets’ record month.
Why Prediction Markets Keep Growing
Elections are only part of the picture.
Fresh off a World Cup that brought in millions of new users, the industry landed its first Congressional hearing on sports contracts this week, a sign regulators are watching more closely as volume keeps climbing. We covered what came out of that hearing, and what’s still unresolved, in a separate piece.
Kalshi has also been building tools for its most active traders, including a new desktop terminal for people running several markets at once, which we detailed here.
None of this settles the bigger legal questions facing the industry, like whether sports contracts belong under state gaming law or federal rules. But growth and scrutiny are moving together here, not against each other, and the Midterms Hub fits that pattern: the more people checking in daily, the stronger Kalshi’s case that these prices matter.
The Takeaway
So next time your phone buzzes with a weather alert, don’t be surprised to see a House race update sitting next to it. Prediction markets used to live in a corner of finance nobody outside Wall Street paid attention to. This November, they’re aiming for your morning scroll.
