Hold to resolution and collect $1 or $0 — or trade the price movement before the event happens. Two fundamentally different strategies with different edge sources, risk profiles, and liquidity requirements.
Every prediction market contract offers you a choice that most participants never consciously make. You can buy at 35¢ and hold until the event resolves — collecting $1 if you're right and losing your stake if you're wrong. Or you can buy at 35¢, watch the price move to 55¢ as new information arrives, and sell before the event happens — pocketing 20¢ without ever learning whether the event occurred.
These are not variations of the same strategy. They are fundamentally different games with different edge sources, different risk profiles, different capital requirements, and different psychological demands. Treating them as interchangeable is one of the most common mistakes in prediction market trading.
In a resolution trade, you buy a contract and hold it until the underlying event occurs (or doesn't). Your contract resolves to $1 or $0. There is no exit strategy, no stop-loss, no trailing profit target. You are making a single binary bet on reality.
Your edge comes entirely from probability estimation. If you buy at 35¢ and the true probability is 45%, you have a positive expected value trade. If the true probability is 30%, you have a negative one. Nothing else matters — not what happens to the price between now and resolution, not the order flow, not the sentiment. Only the final outcome.
Edge source: superior probability estimation. Capital lock-up: until event resolution (could be hours or months). Liquidity requirement: only at entry. Risk profile: binary — full win or full loss. Kelly sizing: straightforward application of the standard formula.
Resolution trading rewards deep domain expertise. The Bundesliga bettor who reads German-language press conferences, tracks training ground injury reports from kicker.de, and understands coalition dynamics in club boardrooms has an information advantage that the market hasn't priced. This edge exists at the moment of entry and the market never needs to agree with you — only reality does.
The disadvantage is capital efficiency. Your money is locked until resolution. A 6-month contract at 40¢ ties up capital that could be deployed in dozens of shorter-duration trades. And the psychological burden is real: watching your contract drop to 15¢ on adverse news while knowing the event hasn't resolved requires discipline that most people don't have.
In a pre-resolution trade, you buy a contract with the explicit intention of selling before the event resolves. You're not betting on the outcome — you're betting on a price movement. Your contract is a vehicle for capturing a temporary mispricing or an information-driven price shift.
Your edge comes from timing and information flow, not from terminal probability estimation. You buy at 35¢ because you believe news is about to break that will move the price to 50¢. Whether the event actually happens is irrelevant — you'll be gone before resolution.
Edge source: timing, information velocity, market microstructure. Capital lock-up: short (hours to days). Liquidity requirement: at entry AND exit. Risk profile: continuous — you can lose any amount between 0% and 100%. Kelly sizing: more complex — must account for expected exit price and slippage.
Pre-resolution trading is closer to equity trading than to betting. You need a thesis not about what's true but about what the market will believe soon. A press conference, an injury report, a polling release, an earnings announcement — any catalyst that moves the contract price creates a trading opportunity regardless of the final binary outcome.
The critical constraint is liquidity. You must be able to exit at a reasonable price. A thin market where you can buy at 35¢ but the best bid when you want to sell is 38¢ eats most of your edge in slippage. Pre-resolution trading is only viable on contracts with sufficient depth on both sides of the order book.
Many experienced traders use a hybrid approach. They enter a position with a resolution thesis (they believe the true probability is mispriced) but set price targets where they'll take partial or full profit before resolution.
For example: you buy a Bundesliga match contract at 28¢ because your model says the true probability is 40%. You plan to hold to resolution. But if an early goal moves the contract to 65¢ with 60 minutes still to play, you sell half — locking in profit while keeping exposure to the full $1 payout. This is analogous to trailing stops in equity trading.
The hybrid works because it addresses the biggest weakness of pure resolution trading: the inability to manage a winning position. A contract that moves from 28¢ to 65¢ represents an unrealised gain of 37¢ per contract. A pure resolution trader watches that gain fluctuate wildly until the final whistle. A hybrid trader locks in some of it.
The Kelly Criterion (article 201) applies differently to each strategy:
Resolution trades: Standard Kelly formula. Your probability estimate and the market price are the only inputs. f* = (p - price) / (1 - price). The edge is either there or it isn't.
Pre-resolution trades: Kelly must account for your expected exit price and the probability of reaching that exit. If you buy at 35¢ and expect to sell at 55¢ with 70% probability (and at 25¢ with 30% probability if the catalyst doesn't materialise), your Kelly calculation uses these expected payoffs rather than the binary $1/$0 resolution.
In practice, pre-resolution Kelly fractions tend to be smaller because the edge per trade is thinner (you're capturing price movements of 10–20¢ rather than the full 65–100¢ gap between entry and resolution). But the capital turnover is much higher, so the total P&L over a season can be comparable.
Both work, but the market structure favours different approaches depending on the contract type:
Sports contracts (match outcomes, player props) suit resolution trading. The events resolve quickly (hours), the information advantage is domain-specific, and there's a clear catalyst (the game). Pre-resolution trading works for live in-play movement but requires fast execution.
Political/macro contracts (election outcomes, Fed decisions) suit the hybrid. They run for weeks or months, information arrives continuously, and the price path between now and resolution is rich with trading opportunities. A contract on "Will the Fed cut rates by June?" might trade between 30¢ and 60¢ multiple times as economic data releases shift expectations.
Novelty/culture contracts (Oscars, reality TV) often suit pure pre-resolution trading because the edge comes from information timing — you hear who won before the market updates — and the contracts are often thin enough that holding to resolution means significant capital lock-up for small payoffs.
Before entering any prediction market position, make the conscious decision: am I holding to resolution or trading the price? Write it down. This single decision shapes your sizing, your exit plan, your liquidity requirements, and your psychological relationship with the trade. Mixing the two without intention is how undisciplined traders turn a well-researched resolution position into a panic sell at the worst possible price.
