Kalshi opened more than 150 insider-trading investigations in the first quarter of 2026, blocked over 100 potential insider trades using automated screening tools, and referred at least 20 cases to law enforcement. The CFTC-regulated prediction market paired the numbers Tuesday with three new compliance tools effective immediately.
The figures come from a June 9 post on Kalshi's news site by Head of Enforcement Robert DeNault. Kalshi also reported five formal disciplinary actions taken in Q1. The new measures include a risk-scoring framework applied to every proposed market before listing, an employment-verification requirement for traders on high-risk markets, and expanded whistleblower tools on every market page.
Kalshi's Q1 statistics mark a step up from the pace disclosed earlier this year. A February enforcement post noted 200 investigations opened over the prior twelve months, with a dozen-plus reaching active-case status. By the end of Q1, pre-trade screening tools alone had blocked more than 100 trades before execution.
The public disciplinary record now spans several categories of insider abuse. In February, Kalshi described two closed cases: a California governor candidate who traded about $200 on his own race (5-year ban, financial penalty equal to 10 times the initial trade), and a YouTube show editor who traded about $4,000 on streaming-platform markets where he had access to non-public scheduling information (2-year suspension, 5 times the trade in penalty). In April, three more political insider-trading cases surfaced involving congressional primary candidates in Minnesota, Texas, and Virginia who had bet on their own elections.
