Kalshi permanently bans former Congressman George Santos over suspected insider trading

Kalshi has permanently banned former Congressman George Santos over suspected insider trading involving bets on his own attendance at the State of the Union address, according to gamblerss.com.

The ban followed an in-depth investigation by Kalshi into those wagers. The account identifies insider-trading suspicions as the basis for the action, rather than an established legal finding.

Bets tied to his own attendance

The reported investigation concerned a market outcome directly connected to Santos’s own conduct: whether he would attend the address. The available summary also references a video he posted, but ends before explaining what he confirmed or how the video related to the wagers.

The report was published on Oct 12, 2026, at 11:54 PM ET. Its full text was unavailable, leaving the supplied material without details on the bets’ timing, size or prices, or Kalshi’s specific investigative findings.

What it means for prediction markets

• Participant-linked outcomes raise integrity questions. Bets on a person’s own attendance put the bettor’s knowledge and ability to influence the outcome at the center of scrutiny.
• The reported sanction is permanent. Kalshi’s action against Santos is described as a ban, not a temporary suspension.
• The evidence remains only partly visible. The available account does not provide enough detail to independently assess the suspected insider trading or reconstruct the sequence of events.
