Why this page is cautious
Availability rules, state-level treatment, and product access can change. A static page should not promise access.
US access
US availability is a fast-changing factual question. ForecastIndex does not guess eligibility; it points readers to current Polymarket checks and alternatives.
Use the table as a research summary, then follow the linked sources for time-sensitive details.
| Reader question | Short answer | Next step |
| Can I sign up? | Verify current platform rules first. | Check Polymarket directly. |
| Can I trade? | Order placement may be restricted by location. | Check current geoblock status. |
| What if I cannot use it? | Compare alternatives. | Read Kalshi vs Polymarket and platform pages. |
| Should I use a referral link? | Only after eligibility checks. | Use the ForecastIndex link if it fits. |
Availability rules, state-level treatment, and product access can change. A static page should not promise access.
A site may be readable while trading or order placement is restricted. The practical question is what actions are available from your location.
Kalshi is useful in ForecastIndex comparisons because it captures a different regulated event-contract intent from crypto-native Polymarket searches.
ForecastIndex discloses the Polymarket link, but the page pushes eligibility checks before signup.
Disclosed referral link
ForecastIndex may earn from the Polymarket link. Use the research pages for invite-link caveats, fees, availability, funding method, and market rules before signing up.
No. ForecastIndex is informational and cannot determine your legal or account eligibility.
Kalshi is the clearest comparison for many US event-contract searches, but readers should verify its current rules too.
