Prediction market legality in the US

Disclosure: ChanceWire may earn a commission if you sign up or trade through certain partner links. SoftCta only until partner tokens allow hard CTAs. Read How we make money and our Affiliate disclosure. Not financial advice. Informational only — not legal, tax, or investment advice. Digital assets and event contracts involve substantial risk of loss.

Not legal advice. ChanceWire is a comparison and data media site, not a law firm or regulator. Rules change. We maintain an internal living CTA / eligibility matrix (Platforms Scout) as the verify source for AgeGate, geo routing, and soft vs production CTAs — public copy here stays high-level so we never ship stale blog state lists.

What this hub covers

• Why “legal in the US” is product- and venue-specific
• How ChanceWire talks about eligibility without access-workaround tips
• VERIFY-oriented product rows (not a contested state encyclopedia)
• Links to platform primers, geo gates, and the US best-of hub

Orientation (high level)

Some U.S. venues market CFTC-regulated event contracts (for example Kalshi and sports-oriented DCMs such as Novig). Other products (including international crypto books) may restrict many U.S. residents. Eligibility is never something ChanceWire can confirm for you — confirm age, location, and product terms on the operator.

ChanceWire’s own geo and age gates are a site safety step for outbound CTAs, not a substitute for KYC or legal counsel. We never publish access-workaround guidance.

Product matrix (VERIFY — not a state blocklist)

Contested Kalshi and Polymarket US state lists from blogs or trackers are not copied here. Ops refresh comes from the Platforms eligibility matrix + live operator UIs before any cell becomes a hard gate.

| Product | Notes | Status |

|---------|-------|--------|

| Federal (CFTC event contracts) | Some venues operate as CFTC-regulated DCMs/exchanges — product rules differ by operator. Confirm on the venue and primary filings. | VERIFY |

| Polymarket (intl) | Many U.S. persons are restricted on polymarket.com; do not conflate with any U.S. Polymarket product. ChanceWire never publishes access-workaround tips. | VERIFY geo on operator |

| Polymarket US | Separate U.S. product with state geofencing that changes with litigation. ChanceWire does not publish blog-sourced state blocklists — check the live app/ToS. | VERIFY in-product |

| Kalshi | U.S.-focused; contract availability can be category- and state-geofenced. Contested sports/election maps move quickly — never treat third-party blogs as final. | VERIFY in-product |

| Novig | Sports-focused DCM; official Help currently frames 21+ and limited state exceptions. Soft CTA only until BD; confirm age/location on Novig before trading. | VERIFY on Novig Help |

| PredictIt & others | U.S.-person and product terms vary. Soft/research framing on ChanceWire unless a partner program is live. | VERIFY on operator |
