Kalshi Trading to Be Available on Nearly 24/7 Basis
One of the biggest prediction market operators, Kalshi, has announced that it is switching its event futures contracts to 24/7 trading. Almost, that is.
On Thursday, the new trade hours will take effect. The announcement was posted on the company's Discord channel on Monday by a Kalshi employee. Except for a two-hour window early on Thursday mornings, clients will now be able to trade Kalshi's derivatives all day, every day.
"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.”
Kalshi prohibited trading between 3 and 8 AM Eastern time prior to the update. However, compared to more conventional markets like stocks and fixed income, its trading hours were noticeably longer. US stock exchanges typically operate from 9:30 AM to 4:00 PM Eastern time.
It might be a wise move. by Kalshi
Since Kalshi filed relevant documentation with its federal regulator, the Commodities Futures Trading Commission (CFTC), last month, the decision to extended trading hours is not unusual. Kalshi self-certified the change.
“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.
Putting aside the lack of surprise, Kalshi's decision to open its trading hours almost around the clock may be a good one, especially in terms of attracting more business from younger retail traders, a very tech-savvy demographic that has grown up with round-the-clock access to cryptocurrency exchanges.
Robinhood Markets is one of Kalshi's partners; it is a popular trading and investing app among younger market participants, many of whom are already doing business with Kalshi.
Kalshi Handling Court Cases
The operator's growing presence in sports event contracts, which detractors claim amount to sports betting and which the prediction markets company lacks regulatory authorization to provide in the state, has resulted in a number of state-level legal disputes that Kalshi is still dealing with.
Judge Adam Abelson of the Maryland District Court denied Kalshi's request for a temporary injunction last Friday, stating that the firm has a substantial burden of proof to support its allegations of field preemption. According to some legal experts, Kalshi and other states may face off at the US Supreme Court as a result of Abelson's decision.
