Prediction markets for campus life

The Polymarket for people who skip class — stay locked in.

Stake on whether you (or your crew) actually show up. Odds move with reputation, streaks, and real outcomes — not vibes.

Why ShowUp exists

Turn “I’ll go tomorrow” into a market with a price on it.

Most attendance apps nag you. ShowUp lets you and your friends bet on real behavior — so skipping has a cost, and showing up pays off. It’s Polymarket energy for the lecture hall: odds shift as your track record updates, not as you update your story.

Skin in the game

You commit stakes for the term — play-money credits or small real amounts you choose. When you ghost class, the market takes its cut; when you lock in, you prove the doubters wrong.

Social accountability

Run markets solo or with your crew. Friends can trade on whether you’ll show — which sounds brutal until it’s the reason you actually go. Reputation becomes visible, not just a group chat promise.

What you’re building toward

Everything on one campus-sized product surface.

  • Semester-long lines

    Set recurring class windows and stakes once; we track outcomes across the term so one-off excuses don’t reset the board.

  • Location-backed check-ins

    Tie attendance to places and times you define — so resolutions reflect whether you were really there, not whether you said you were.

  • Markets, not guilt trips

    Buy and sell side bets with friends on attendance outcomes — prices move as people’s streaks and slip-ups become public knowledge.

Trust & fairness

Markets only work if everyone knows how they end.

ShowUp is designed so outcomes are explainable: your bets resolve from check-ins and rules you can read in plain English — not a black box score or a roommate’s opinion.

  • Clear resolution rules

    Every market spells out what counts as “showed up,” when it settles, and what data we use — before anyone puts stakes down.

  • Built for real campuses

    Schedules, buildings, and weird section times are first-class — not an afterthought on top of a generic habit app.

  • You stay in control

    You choose what to stake, which classes to track, and who can see your markets. We’re building for opt-in accountability.

How it works

Three steps from idea to settled market.

  1. 01

    Set your line

    Bet on yourself by putting money into the app. Set your stake for the semester - the more you commit, the more you have to lose (or prove).

  2. 02

    Go to class

    Add your class locations and schedules. The app tracks your location during class time - show up and you're safe, skip class and lose your stake.

  3. 03

    Settle the market

    Location data automatically resolves your bets. Attendance is verified, money is deducted for absences, and your reputation is updated.
