Kalshi caps deposits for traders aged 18 to 20 ahead of US midterms

Kalshi is tightening the rules for its youngest customers. The CFTC-regulated prediction market said on October 27 that it is adding new guardrails for traders aged 18 to 20, with the US midterm elections approaching.

The centerpiece is a $2,500 monthly deposit limit for that age bracket.

What Kalshi is changing

The new measures are aimed at curbing addiction and promoting responsible trading among young adults. The deposit cap is the headline item, but it does not stand alone.

Kalshi is also rolling out automated alerts for newer users. They trigger when a trader puts more than 25% of their balance into a single market contract.

The exchange is pairing those controls with outreach to families. Kalshi is working with Parent ProTech and ConnectSafely to publish educational guides that explain prediction markets to parents.

Kalshi’s management frames the platform as working much like a stock exchange, available to anyone 18 or older. The new rules leave that age floor in place. They simply add friction for customers on the younger end of the eligible range.

A small slice of volume, a big slice of attention

On paper, the affected group is a modest share of Kalshi’s business. Traders aged 18 to 20 account for just 4% of the exchange’s trading volume.

The typical Kalshi user is older than the headlines might suggest. The median trader age on the platform is 29.

The latest steps also build on security work from earlier in 2026. Kalshi previously made facial recognition, including Face ID, the default, and it beefed up two-factor authentication. It also added verification checks for high-risk trading patterns.

Why prediction markets are under the microscope

Kalshi became a CFTC-designated contract market after receiving approval in November 2020. It settles contracts primarily in US dollars and enforces strict know-your-customer requirements, meaning users must verify their identity before trading.

The broader industry is facing heightened examination over its resemblance to gambling and the risk of youth addiction. The pressure has grown as trading volume in sports contracts climbs.

What this means for Kalshi and its rivals

The most immediate effect is on Kalshi’s own youngest customers. A monthly deposit ceiling limits how much fresh money they can bring in, which caps the downside of a bad streak.

The 25% concentration alert is softer. It warns rather than blocks, leaving the final decision with the trader.

With the 18-to-20 cohort representing 4% of volume, even a meaningful pullback from that group would barely dent overall activity.
