Do availability checks first
A strong review or referral offer does not matter if the reader cannot use the platform under current rules.
Availability
Polymarket availability changes by location and platform rules. ForecastIndex treats availability as the first check before fees, app experience, or referral links.
Use the table as a routing tool, then verify current platform rules directly before signup or participation.
