Kalshi Imposes $2,500 Monthly Deposit Cap on Traders Under 21
Key Takeaways
- •Kalshi will automatically move users aged 18 to 20 into special accounts with a $2,500 monthly deposit limit, and those holding more than $1,000 will receive an alert if they place over 25% of their balance on a single trade.
- •The platform's minimum age remains 18, with co-founder and COO Luana Lopes Lara arguing that Kalshi, like a stock exchange, is available only to traders 18 and older.
- •New York's Attorney General is suing Kalshi for allegedly operating illegal gambling open to people under 21, while the state's Gaming Commission has gone to court to obtain records on the company's under-21 users and sports contracts.
- •The bipartisan Prediction Market Act, co-sponsored by Sen. Kirsten Gillibrand, would impose tighter CFTC oversight with mandatory age verification and self-exclusion tools, and the NBA and PGA Tour have each pushed for a 21-and-over minimum age.
- •Traders aged 18 to 20 account for roughly 4% of Kalshi's trading volume, and the new cap applies only to fresh deposits, leaving existing balances and winnings unrestricted while the 25% alert can be dismissed by users.

Prediction market platform Kalshi is introducing new consumer protection measures for its youngest users as regulatory scrutiny of the event-based trading platform intensifies. The changes cap how much money traders under 21 can bring onto the platform.
Unlike a traditional sportsbook, Kalshi operates as an exchange overseen by the Commodity Futures Trading Commission, where users trade contracts tied to real-world outcomes such as election results, economic data releases and sporting events. That hybrid identity — trading venue or gambling operation — sits at the center of the regulatory fight now surrounding the company. In most U.S. states, legal sports betting is already restricted to users 21 and older, a benchmark that has featured prominently in criticism of prediction markets' 18-and-over model.
According to a Bloomberg report, Kalshi said on October 27 that users aged 18 to 20 will automatically be moved into "special accounts" carrying a monthly deposit limit of $2,500. Members of this group who hold more than $1,000 will also receive an alert if they place more than 25% of their balance on a single trade.
Kalshi says the changes are intended to strengthen education for newer traders. The platform's minimum age remains unchanged, with co-founder and COO Luana Lopes Lara stating that "like the stock exchange, Kalshi is available only to traders 18 and older."
Mounting Legal Pressure From New York and Washington
The announcement lands as the platform faces significant legal pressure. New York's Attorney General is suing Kalshi for allegedly operating illegal gambling that is open to people under 21. Separately, the state's Gaming Commission has gone to court to force the company to hand over records on its under-21 users and sports contracts.
Washington presents another front. The bipartisan Prediction Market Act, co-sponsored by Sen. Kirsten Gillibrand, D-N.Y., would place prediction markets under tighter Commodity Futures Trading Commission (CFTC) oversight, with mandatory age verification and self-exclusion tools. The NBA and PGA Tour have each pushed for a 21+ minimum age. Their involvement reflects how closely prediction-market sports contracts mirror the conventional sports wagering those leagues sit alongside — the very characterization Kalshi contests. All of this is unfolding less than a week before the midterm elections.
Kalshi Leans on Stock Exchange Comparison
Kalshi's core argument for keeping its minimum age at 18 is that it operates as a federally regulated exchange, more comparable to a stock exchange than a sportsbook. The new rules make that comparison harder to sustain: a 19-year-old can open a brokerage account, deposit $50,000 and put the entire sum into a single stock without any deposit caps or diversification alerts.
Critics argue the measures for this age group signal that the platform is effectively conceding that it carries gambling-like risk for young users. Benjamin Schiffrin, director of securities policy at investor-protection group Better Markets, described the limits as a "pretty stunning admission" about the real nature of the platform, according to Bloomberg.
The Cap Still Leaves Considerable Room
Commercially, Kalshi is giving up little. Traders aged 18 to 20 account for roughly 4% of the platform's trading volume — at Kalshi's scale, that still represents billions of dollars in sports trades this year, though it remains a small slice of the overall business.
The limits are also softer than they first appear. A $2,500 monthly cap adds up to $30,000 a year in fresh deposits. The cap applies only to new money, and nothing in Kalshi's announcement restricts how much a young trader can stake from funds already in their account, winnings included. The 25% concentration alert is merely a warning: users can dismiss it and place the trade anyway.
The questions that will define the next phase are concrete: whether New York's courts side with the company or its regulators, whether the Prediction Market Act gathers support in Congress, and whether the new limits visibly change how the platform's youngest cohort trades.
