You can be completely right about an outcome and still lose money if you enter too early, too late, or exit at the wrong moment. Prediction market timing is a distinct skill from outcome forecasting — and it is equally important.
The Three Entry Windows
- →Market open (first 24-48 hours): prices are often poorly calibrated, widest mispricings, also highest uncertainty
- →Post-information-arrival: after major data releases or news events, brief windows before full repricing
- →Pre-resolution (48-96 hours out): sentiment traders make final bets, sometimes creating overreactions
The Holding Problem
Prediction markets are not investments. They have defined resolution dates. Holding a position too long ties up capital that could be redeployed elsewhere. The optimal hold period balances expected value against opportunity cost. If a position is at 85% and you think it should be at 90%, the remaining 5% of edge may not justify the capital commitment until resolution.
A 5% edge on a position that resolves in 2 weeks is better than a 5% edge on a position that resolves in 6 months. Time value is real in prediction markets.
When to Exit Early
Exit early when: new information materially changes the probability, the remaining edge is too thin to justify the capital, or you identify a better opportunity. Do not exit early because you are nervous or because the position is briefly moving against you — that is noise-driven trading, and it destroys returns.
"The best prediction market traders are patient in identifying edges and ruthless in abandoning them when the edge disappears."
