Bottom Line

Congressional scrutiny of prediction markets has intensified with a formal insider‑trading probe. Investors should expect higher compliance costs and possible restrictions on on‑chain betting protocols.

House Oversight Chair James Comer opened a probe on May 24, 2026, into Kalshi and Polymarket for alleged insider trading. The investigation could tighten regulatory oversight, squeezing liquidity for crypto‑based prediction markets.

Why This Matters to You

If you hold tokens that power prediction‑market protocols, stricter rules may reduce trading volume and increase fees. A ban on U.S. platforms would push users toward unregulated, higher‑risk venues.

Probe Heightens Compliance Costs for Token Issuers

The congressional inquiry forces Kalshi and Polymarket to beef up KYC (know‑your‑customer) and AML (anti‑money‑laundering) controls. Both firms have already announced enhanced safeguards, but the probe adds a layer of legal risk that could delay product launches (Confirmed — Decrypt).

For token issuers that rely on these platforms for market‑making, the added compliance burden translates into higher operating expenses. Expect tighter smart‑contract audits and potentially larger escrow requirements.

Lobby Group Aims to Shape Future Regulation

Kalshi’s newly formed Americans for Fair Markets (AFM) hired former White House aide Taylor Budowich as strategic advisor to counteract “gaming lobby” pressure (Confirmed — Decrypt). The group argues that a blanket ban would push betting offshore, eroding consumer protections.

If AFM succeeds, Congress may adopt a lighter‑touch framework that preserves identity verification and insider‑trading rules for regulated platforms, preserving on‑chain liquidity.

On‑Chain Liquidity Risks Shifting to Unregulated Venues

Should lawmakers favor the gaming lobby’s call for an outright ban, traders could migrate to decentralized prediction markets lacking KYC or AML safeguards. Those venues would operate without CFTC oversight, increasing fraud risk (Analyst view — JPMorgan).

Liquidity migration would depress token prices on regulated platforms, while boosting demand for privacy‑focused alternatives, reshaping the on‑chain betting landscape.

What to Watch

  • Watch Kalshi (KAL) SEC filing updates (this week) — new compliance disclosures could affect token valuation.
  • Watch House Oversight Committee hearing transcript (next month) — any subpoena to Polymarket may trigger market reaction.
  • Watch CFTC rule‑making agenda (Q3 2026) — potential guidance on crypto‑based prediction markets could set industry standards.

AFM’s lobbying secures a regulated framework, keeping on‑chain liquidity and enabling token growth.Congress backs a ban, driving users to unregulated platforms and collapsing token demand on compliant exchanges.

Will the emerging regulatory push preserve a safe, on‑chain prediction market ecosystem, or will it drive activity into the shadows?
