Strategy 08
Event Contracts
Outcomes, priced as probabilities.
An event contract pays a fixed amount if a defined outcome occurs and nothing if it does not. Its price is the market’s probability estimate. Wesvel trades those probabilities where they are mispriced, and uses them to hedge event risk elsewhere in the book.
What is traded
Contracts on scheduled macro releases, central bank decisions, regulatory determinations affecting digital assets, protocol upgrades and governance votes, and other outcomes with an objective, publicly verifiable resolution. Contracts without a clear resolution source are not traded.
Venues
Two venue types exist with different regulatory standing: federally regulated designated contract markets that list event contracts under CFTC oversight, and on-chain prediction markets that settle through smart contracts and oracles. Wesvel evaluates each venue on the same axes as any exchange, custody of margin, resolution rules, and legal access for the fund, and restricts activity to venues its counsel has cleared.
Probability pricing
A contract quoted at a given price implies a probability. The strategy compares that implied probability to its own estimate, built from the same data the market has, and to the price of the same or an equivalent outcome on other venues. Positions are taken only where the gap is wider than the cost of holding to resolution.
Finding mispricing with AI
Event markets are wide and thin. Hundreds of contracts are open at once, most attract little analysis, and prices move on attention rather than information. That is a search problem before it is a trading problem, and Wesvel uses machine learning and language models to run the search: reading news, filings, polling, data releases and on-chain state continuously, producing a calibrated probability for each contract, and comparing it with the market’s price on every venue that lists the outcome.
Where the model’s probability sits far enough from the market’s, after fees, spread and the time to resolution, there is positive expected value, a positive delta between what the contract should cost and what it does. The models also parse resolution rules to confirm that two venues are pricing the same outcome before a cross-venue arbitrage is treated as one. The models propose; a person reviews the reasoning and sizes the trade. The systems are built and run in-house on the principles described in our AI Systems practice, so that the data and the models stay inside the firm.
Cross-venue relative value
The same event is frequently listed on more than one venue at different prices. Buying the outcome where it is cheap and selling it where it is rich locks in the difference regardless of how the event resolves, provided the contract definitions match. Definition mismatch is the primary risk in this trade and is reviewed before every position.
Hedging portfolio event risk
Several Wesvel mandates carry exposure to discrete events, a regulatory ruling, a network upgrade, a rate decision, that is difficult to hedge with price instruments. An event contract on the specific outcome is a direct hedge. Used this way, the contract is sized to the exposure it offsets, not to a view.
Position limits and lock-up
Capital in an event contract is committed until resolution or until the position can be exited in a secondary market that may be thin. Exposure per event, per venue, and per resolution source is capped, and the aggregate mandate is sized as a small share of the fund.

- 02Venues and RegulationRegulated designated contract markets versus on-chain prediction markets, and how an unsettled regulatory position shapes what the fund can do.
- 03Probability PricingHow a contract price implies a probability, how the mandate forms its own estimate, and why the gap has to be wide.
- 04AI and Mispriced ProbabilitiesHow machine learning and language models screen hundreds of event contracts for prices that disagree with a calibrated estimate, and how that gap becomes a position with positive expected value.
