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#

CriterionRule
Price band5¢ – 95¢
In-playNo — entry halts at event start
Spread and depthPublished thresholds, checked continuously
Resolution horizonBounded and stated on listing

Delisting never touches an open position. A market removed from the allow-list stops accepting new entries; yours runs to resolution.
