Kalshi adds a default $2,500 monthly deposit limit for 18- to 20-year-olds

Barron's reports Kalshi is instituting a default $2,500 monthly deposit limit for 18- to 20-year-olds on its prediction market. Reuters says the expanded safeguards are intended to curb addiction and promote responsible trading ahead of US midterm elections. Barron's also notes a federal bill introduced in March that proposes barring online prediction markets from accepting wagers from anyone under 21.
