Prediction Market Insider-Trading Enforcement Tracker
Three regulatory tiers — exchange discipline, CFTC civil, DOJ criminal — across Kalshi and Polymarket. Seven tracked enforcement or discipline cases, a parallel suspicious-but-unindicted tier, and eight legislative entries.

Corroborating sources:
What this does not mean:
- Does not mean the CFTC has abandoned PM enforcement — the agency has filed its first event-contract insider-trading complaint (Van Dyke) within the same week.
- Does not mean exchange-tier discipline (Kalshi self-policing) is failing — Kalshi has shipped four enforcement actions in 11 months.
- Does not project staffing trends; reflects a single Sunday-AM canonical explainer plus three corroborating Tier-1 pieces filed Apr 24.

Methodology guardrails
- Case rows render with charge details and primary-source URLs only — never paraphrased prosecutor narrative.
- Suspicious-but-unindicted rows display a persistent 'No charges filed — alleged only' badge and never use the words fraud, theft, or scam in the row body.
- Dollar amounts are echoed only when they appear in a CFTC press release, DOJ indictment, exchange enforcement notice, or sworn court filing.
- Unsourced excerpts are omitted from the page until source review clears them; placeholder text never goes live.
- Source-review notes are the single home for Tier-1 frame shifts; secondary press is used only as corroboration and never manufactures a second shift entry.
- Suspicious-but-unindicted tier never names individuals beyond what the primary source named; pseudonymous wallet clusters stay pseudonymous.
- Congressional-bills column links to congress.gov primary URLs only; co-sponsor counts cite the congress.gov record, not press summaries.
- Cross-platform parity is preserved row-for-row — never let Kalshi disclosure asymmetry skew the tier counts.
- Pardon-watch and political-conflict context stays in source-review notes, never in the case-row body.
- Page never rank-orders defendants by 'most egregious' — chronology is the only permitted sort axis.
