It imposed a five-year ban, and imposed a fine on the account amounting to 10 times the size of the initial trade, which Calci says it intends to donate to charity.

While Calci did not mention the candidate by name, Denault noted that they recently dropped out of the race and switched to running for Congress. This fits the description of only one person in the race: Kyle Langford, a far-right Republican candidate known for his inflammatory anti-Semitic comments. Praising the Nazis. Langford has since dropped out and campaigned as a progressive Democrat in California’s 26th District.

In May 2025, Langford posted a video on X showing a screen recording of a business order submitted to Calci for an event in the gubernatorial race.

It also received concurrent tips from Calshi users, who reported unusual activities. “We investigated and found that the trader was serving as an editor for the live stream show and likely had access to material non-public information related to his trading,” DeNault wrote in the report. The account was frozen before he could withdraw funds; He has now been suspended for two years and also received a financial penalty. Kalshi did not reveal the identity of the broadcaster on YouTube.
