House rules
How we write a market guide
Resolution text first, then cents. Sample contracts are archetypes. We do not invent volume, open interest, or a “market favorite.” Sports-themed contracts stay in cents — we will not convert them to juice.
Editorial guides
Prediction Market Categories
A politics contract and a weather contract both settle as cents or $0–$1 shares. Sample quotes are teaching props — no live book, no wallet, no trade ticket.

“Compared on” means the brand page already points at that category — not that the venue lists every contract in it, and not that you can open an account from every state. Snapshot as of Sep 2026.

A category is not a state map
A venue may list a national politics contract and still geoblock a given state. Read the state notes and the platforms board. The app's own eligibility screen is final.
