Same Market, Two Prices
Some questions are traded on more than one site at the same time — and the sites don’t always agree on the odds. Here’s where they disagree most.
- 🎯 A prediction market lets people bet on whether something will happen. Its price acts like a percentage: “42%” means the market thinks there’s a 42% chance it happens.
- 📊 Each row below is one possible outcome, with that percentage on each site that trades it.
- ↔️ The gap is how far apart the sites are. Example: if one site says 20% and another says 24%, that’s a 4-point gap — one of them may be mispriced.
- ⚠️ A gap is a lead to investigate, not free money. The two markets can settle on slightly different terms (dates, wording, source), and trading has fees. Always open both and check before acting.
