Current reporting can explain adoption and distribution, but it does not settle legal access or contract mechanics.<\/p>\n<p>Every fact is bound to a venue. International Polymarket protocol documents apply to that protocol. A Polymarket US filing applies to the named US contract family. Kalshi help and filings apply to Kalshi products under their current scope. Interactive Brokers pages describe eligible client access and published schedules that can vary by program.

We review best bid and offer, spread, depth at several levels, recent executed activity, likely market impact, and whether an exit can be placed before settlement. Platform-wide volume receives little credit because it can be concentrated in unrelated markets.<\/p>\n<p>A market can show a probability-like midpoint without an executable price there. Limit orders can reduce price uncertainty but add non-fill risk. A wide spread is a direct cost.

A reviewed Polymarket US filing describes official source hierarchies for one contract family. Kalshi product filings tie settlement to exchange rules and specific contract terms.
