Details
Play money. BRB can't be bought, sold, transferred, or cashed out, and there are no prizes.
Pricing. An automated market maker always takes the other side of your trade, so you can trade any time. Larger trades move the price more; you see your average price before you confirm.
Resolution. Every market lists its rules and sources. Markets resolve from official announcements or credible reporting. Cancelled markets refund every position.
Content rules. Not allowed: markets about private individuals (students, TAs, non-public staff), anyone's relationships, health, deaths, assaults, discipline or Title IX cases, immigration status, or a single student's grades/admissions. Public figures in their public role, campus events, sports, weather, and aggregate stats are fair game.
