SPECULATION VS. HEDGING ON PREDICTION MARKETS
The same market can be a speculative bet or a portfolio hedge depending on what else you own. Understanding which one you're doing changes how you size and when you exit.
Speculation on prediction markets means you're taking a position because you believe the price is wrong — you think YES is undervalued or overvalued and want exposure to your view. Sizing is governed by your edge and bankroll management; exits are governed by price reaching your target.
Hedging means you're taking a position to offset risk somewhere else in your life or portfolio. A portfolio manager long US equities might buy 'Recession in 2025: YES' as a hedge. A homeowner in Florida might buy 'Major hurricane this season: YES.' The position is sized to the underlying exposure, not to your edge in the market itself.
The big mistake is conflating the two. Hedgers who get sucked into speculating tend to remove the hedge once it's in profit (re-exposing themselves). Speculators who reframe a losing trade as a 'hedge' tend to oversize and ride it to zero. Define your reason for the trade before you place it, and exit on that reason failing.
Side by side
| Aspect | speculation-pm | hedging-pm |
|---|---|---|
| Reason for entry | Edge on the price | Offset external exposure |
| Sizing input | Bankroll fraction | Underlying exposure size |
| Exit trigger | Price target or stop | Underlying exposure changes |
| Result if right | Profit on the trade | Loss on the trade, gain elsewhere |
Bottom line
Write down which one you're doing before you click buy. Hedges should be sized to the thing you're protecting against, not to your conviction. Speculative bets should never be larger than 1–3% of your bankroll per market.
