- Prediction markets operator will permit trading all day, every day … almost
- There will be a two-hour closure window for maintenance early on Thursdays
Kalshi, one of the largest prediction market operators, says it’s transitioning to 24/7 trading on its event futures contracts. Well, almost.
The new trading times go into effect on Thursday. A Kalshi staffer made the announcement Monday on the company’s Discord channel. Going forward, clients will be able to trade derivatives offered by Kalshi all day, every day, save for a two-hour window early Thursday mornings.
The night owls have been asking… when can we trade overnight? We are super excited to announce our brand new trading hours!,” according to the post. “Starting this Thursday (August 7th, 2025) at 5am ET, Kalshi will be open 24/7 for trading with the exception of routine maintenance. Maintenance will occur weekly from 3am – 5am ET on Thursday mornings.”
Before the update, Kalshi didn’t permit trading between 3 and 8 AM Eastern time. Still, its trading hours were significantly longer than traditional markets, such as equities and fixed income. Standard hours for US stock exchanges are 9:30 AM to 4 PM Eastern time.
Could Be Smart Move by Kalshi
Kalshi self-certified the move to extended trading hours, and the transition isn’t surprising because it filed related documents with the Commodities Futures Trading Commission (CFTC) — its federal regulator — last month.
“This filing is to provide notice that the schedule of maintenance windows announced on the website will be changed, such that maintenance windows will occur, and trading will not be available on Kalshi, during the following times: On a regular basis, from the hours of 3:00 AM ET to 5:00 AM ET on Thursdays,” according to the document.
Lack of surprise aside, Kalshi’s move to nearly 24/7 trading hours could be smart, particularly when it comes to garnering more business from younger retail traders — a segment of the investing public that’s highly tech-savvy and one that’s grown up with 24/7 access to cryptocurrency markets.
One of Kalshi’s partners is Robinhood Markets — an investing and trading app beloved by younger market participants, many of whom are already bringing business to Kalshi.
Kalshi Dealing with Legal Battles
Kalshi continues grappling with a slew of state-level legal battles, which have come about by the operator’s increasing footprint with sports event contracts, which critics say amount to sports betting — something the prediction markets firm doesn’t have regulatory approval to offer in the state.
Last Friday, Judge Adam Abelson of the Maryland District Court rejected Kalshi’s request for a temporary injunction, noting the company faces significant burden in proving its field preemption claims. Some legal experts believe Abelson’s ruling could set up a showdown between Kalshi and various states at the US Supreme Court.
