100+ Insider-Trading Cases Flagged in 2026 as CFTC Lags

Platforms flag potential insider activity

Kalshi has signaled 50 instances involving potential insider trading, while Polymarket has signaled approximately 90, according to gamblerss.com. The figures concern activity in 2026 and include domestic and overseas instances.

The reported counts put Polymarket’s total at nearly twice Kalshi’s. They describe potential insider activity, not established violations.

Regulatory context remains limited

The gamblerss.com summary portrays the Commodity Futures Trading Commission (CFTC) as reduced in capacity and lagging behind the flagged activity. However, the available summary cuts off before explaining what the agency lost or how that affected its response.

The source’s full article was unavailable. The supplied material does not identify the markets or traders involved, describe the evidence behind the flags, or specify whether any instance has led to enforcement action.

What it means for prediction markets

• Flags are not findings: Kalshi’s 50 instances and Polymarket’s approximately 90 should not be treated as confirmed insider-trading violations.
• Enforcement outcomes remain unclear: The available reporting does not establish how many instances, if any, are under CFTC investigation.
• Contract-level implications cannot be assessed: Without details on the affected markets or conduct, the figures alone do not establish an impact on particular contracts or their outcomes.
