Young Kalshi users have traded an estimated $3.9B on sports and parlay-type contracts this year, exposing a loophole that lets them bet before age 21

Young users on the Kalshi prediction market have been trading an estimated $3.9 billion on sports-related contracts this year, sparking concerns over a potential loophole in gambling laws. According to a recent analysis by CNN, users between the ages of 18 and 21 accounted for $5.4 billion in trading activity on the platform. While sports gambling is prohibited for anyone under 21 in most states, Kalshi operates as a financial market under the Commodity Futures Trading Commission's jurisdiction, allowing users 18 and older to participate.

The discrepancy in age restrictions between Kalshi and sports gambling organizations has prompted legal challenges. New York State is currently suing to shut down Kalshi, claiming it operates an unlicensed gambling platform. Despite Kalshi's spokesperson stating that users aged 18 to 21 comprise only 3.14% of its trading volume, critics argue that the platform's design resembles gambling, particularly through its "combos" feature that functions similarly to parlay bets.

Les Bernal, the national director of Stop Predatory Gambling, expressed worry over young people accessing such platforms at a young age, citing the addictive nature of these products and the potential harm to vulnerable individuals. A peer-reviewed paper published in Science warns that the architecture of commercial prediction markets can lead to behavioral addiction due to continuous novelty and infinite event streams, which may weaken prefrontal inhibitory control and promote compulsive use.

Kalshi maintains that it should not be regulated like sports betting or online casinos as it merely connects users on opposite sides of a financial transaction and operates a neutral marketplace. However, the 9th U.S. Circuit Court of Appeals recently ruled that Nevada can impose state law against Kalshi's sports-related event contracts, effectively blocking the platform from offering them in Nevada without complying with state gaming laws.
