The market universe
In one line: curated, because a thin book is an attack vector.
Why curated#
A thin book is an attack vector: with enough size relative to depth, a trader can move the mark their own floor is measured against. Curation is a risk control, not an editorial position.
Categories at beta#
Curated allow-list: sports + crypto events at beta. Politics deferred.
Politics is deferred — not because it is uninteresting, but because its resolution disputes are the longest and its regulatory position is the least settled.
Listing criteria#
Delisting never touches an open position. A market removed from the allow-list stops accepting new entries; yours runs to resolution.
