The absurdly over-serious prediction exchange for group trips. Markets open.
The premise
Wager Weekend is a play-money prediction market for your group trip. Someone starts a group, sets a theme, and everyone gets a fake bankroll. The goal is simple: finish the weekend with the most money. No buy-ins, no cash value, no real-world payouts.
Your seat is yours: the 4-digit PIN
When you first enter an exchange you pick a 4-digit PIN. That PIN, plus your display name, is how you get back to your seat later — and it's what stops anyone else in the group from signing in as you and betting your bankroll. You'll also need it to recover a forgotten group code. Forget your PIN and the Commissioner can reset it from the SEC desk; the reset gets posted to the tape, so nothing happens quietly.
Starting or joining a group
The host creates an exchange, picks a theme like “Bachelor Party” or “Fishing Trip,” sets when markets open and close, and chooses a starting bankroll and liability cap. Everyone else joins with a six-character code and a display name.
The event generator — the groom, guest of honour, or person everyone is betting on — gets a special role with no bankroll and no betting. Their job is to be unpredictable.
Pre-market: list early, trade at the bell
As soon as the group is open, anyone can list markets — question, outcomes, opening odds, house liability cap. Nothing can be wagered yet.
At the group’s designated start time, the whole pre-market book goes live at once at its opening lines. From that moment, wagers execute, odds start moving with the money, and normal rules apply.
Bankroll & house liability
Every player starts with the same fake bankroll. When you propose a market, you become the house. You must cover potential payouts, so your outstanding liability is capped per player. The platform shows your current exposure in real time. If you are taking too much heat, close the market.

Proposing a market
Tap “+ Propose a market.” Enter the question, pick a type (Yes/No, Over/Under, First To, Exact, Time), set the opening odds, and choose a maximum house liability. You cannot bet on your own market — that would be an obvious conflict.
Example: Steve opens a market on whether Dave will fall asleep before midnight. He posts YES at 2.0x and NO at 1.7x. As money comes in, the odds move automatically.
Dynamic odds
Prices are not fixed. As more money piles onto one side, that side gets cheaper and the other side gets longer. The market finds its own price based on where the group is willing to put money.
Settlement & voting
When a market closes, bettors vote on the outcome. The majority wins. If the result is disputed, the Commissioner — the person who started the group — can settle or void the market. Voided markets refund all bets. Commissioner rulings are final and frequently unfair.
The SEC: report manipulation
If the house rigs the outcome, leaks inside information, or writes a deliberately ambiguous question, anyone can report it. The Commissioner can investigate and ban the offender. Common violations: insider information, collusion, refusing to pay out, bad faith markets, and “that absolutely was not what the bet meant.”
