Prediction markets let people bet on the outcome of future events — elections, whether a price hits a level, sports results, policy decisions — by trading shares whose payout depends on whether the event happens.
The core idea: price = probability
- Every event has two sides, e.g. "Will the Fed cut rates in June?" — Yes vs. No.
- Each share is worth $1 if correct, $0 if wrong.
- A "Yes" share trading at $0.60 means the market collectively prices that outcome at ~60% probability. It's a continuously-updating crowd forecast.
How you make money
- Buy a share at $0.60; if the event happens you get $1 — a 66% return.
- You can also trade before resolution — sell at $0.75 if the odds move in your favor, pocketing the difference without waiting.
Why they're useful
- The price is essentially a real-time, skin-in-the-game forecast, which research has shown is often more accurate than polls or expert opinion (better incentives — people put money where their mouth is).
- Traders can hedge real-world positions and express genuine beliefs.
The mechanics / crypto angle
- Crypto prediction markets (Polymarket, Augur, Azuro) run on-chain: outcomes are resolved by oracles/DAOs, payouts settle via smart contracts, and positions are just tradable tokens — no bank or clearinghouse needed.
- Traditional ones (betting exchanges like PredictIt) rely on a central operator to hold funds and pay out.
Key risks
- Resolution disputes — if the "correct" answer is ambiguous, oracles can be gamed or contested (this is the biggest structural weakness).
- Thin liquidity — obscure events may have wide spreads and few buyers.
- Censorship/legal risk — many jurisdictions restrict political or sports betting markets.
- The price isn't a guarantee — it's an average opinion, not a fact, and can be distorted by manipulation or low volume.
