Write down the original contract’s entry cost, payout, fees, expiration and settlement rule; model the original and hedge together in every possible outcome; and commit no more risk capital than remains after living expenses and savings needs. If the combined worst-case loss or required cash exceeds your limit, reduce the hedge, close part of the original position, or do not add a second position. A hedge can reduce exposure, but it cannot guarantee a profit or remove every risk.
Event-contract rules differ by venue and market. Confirm the exact contract language, current fees, liquidity, trading permissions and jurisdictional terms before placing an order. The Commodity Futures Trading Commission’s event-contract guidance and its glossary provide the basic framework, not a universal retail hedge ratio.

What risk are you actually hedging?
A prediction-market position is an exposure to a defined event, not simply a bet on a ticker symbol. Many contracts use a yes/no outcome, a fixed payout usually described as $1, and an expiration. Other contracts can have several choices or partial payouts. The traded price reflects the market’s perceived likelihood, while fees and taxes change the result you receive. Read the contract specification rather than inferring terms from a similar-sounding market.
For a long YES position, the obvious risk is a loss if the event resolves NO. But your real exposure may be narrower or broader: a particular date window, threshold, data source, geographic area, or settlement methodology can determine whether the payout occurs. A proposed hedge should target that defined exposure. Buying a contract that merely mentions the same subject can leave you exposed to basis risk—the possibility that the two positions resolve differently.

The CFTC uses hedging to mean taking an opposite derivatives position to reduce loss risk from an adverse price change. Its example is a citrus farmer buying a weather contract to offset possible freeze damage. That logic—identify the loss, then add an offsetting payoff—transfers to event contracts only when the event, timing, units and settlement source line up.
Set a bankroll limit before choosing a hedge
There is no source-backed universal percentage of a bankroll that every retail trader should risk, and there is no standard hedge ratio that fits every event contract. Set a personal dollar ceiling first. The CFTC’s consumer instruction is: Only trade with risk capital, or money you can afford to risk after living expenses and other savings needs have been met.
Read the full guidance at cftc.gov/LearnAndProtect/PredictionMarkets.
Your limit should include both the money already committed and the proposed hedge. Treat a position as unsuitable if its maximum combined loss would interfere with rent, bills, emergency savings, debt payments or other planned needs. Do not increase the limit because the original position moved against you; that is a new decision, not a reason to chase the trade.

Write a one-page risk brief
- Market and venue: Record the exact contract name, venue, account type and jurisdiction.
- Original position: Note YES or NO, number of contracts, entry price, commissions or other fees, collateral requirement and settlement date.
- Target: State the loss or exposure you want to reduce. “I dislike losing more than $X if the event resolves NO” is more useful than “I want protection.”
- Combined limit: Set the largest loss and largest additional cash commitment you will accept after adding a hedge.
- Exit rule: Decide in advance whether you will close, reduce or hold if liquidity deteriorates, the event definition changes, or the market approaches settlement.
This brief turns a vague desire for safety into a testable decision. If the proposed order fails the test, the correct action is to change the size or walk away.

- Copy the original contract terms. Record the payout for every outcome, the entry cost, fees, expiration, settlement source and any early-trading rules. For a simple fully paid contract, the pre-fee result in a winning outcome is the payout minus the entry cost; in a losing outcome it is the entry cost forfeited.
- Define the exposure to reduce. Identify the specific outcome, date window and loss amount that matters. If you care about a $40 loss in one scenario, use that number rather than a percentage borrowed from another trade.
- Describe the proposed hedge. Enter its contract count, price, cost, fees, possible payout and settlement conditions. Include collateral or margin if the product uses it.
- Calculate every relevant scenario. For each outcome, add the original net result and the hedge net result. Use
combined result = original result + hedge result. Include fees in the same scenario rather than treating them as an afterthought. - Find the worst case. The largest negative combined result is the loss to compare with your risk limit. Also note the best case, the residual loss in the outcome you are hedging and how much cash remains locked until settlement.
- Check the match. Confirm that both contracts refer to the same event definition, time window and settlement source. A mismatch means your worksheet needs separate scenarios; do not treat the hedge as an exact offset.
- Check execution. Test whether the order size can realistically be filled and whether you could exit later. A displayed last price is not a promise that your entire order will execute there.
- Apply the limit. If the combined worst-case loss or additional cash requirement breaches your preset ceiling, lower the size, reduce the original position instead, or decline the hedge.
Illustrative worksheet (not a recommendation)
Assume, purely for illustration, 100 YES contracts bought at $0.40 each. Before fees, the original cost is $40; a YES resolution pays $100 and produces a $60 gain, while a NO resolution loses $40. Suppose a trader buys 60 NO contracts at $0.60 each for another $36. If the event resolves YES, the combined result is $60 minus the $36 hedge cost, or $24. If it resolves NO, the original loses $40 and the NO hedge pays $60, leaving a $24 hedge gain and a combined result of negative $16. The hedge reduces the modeled downside from $40 to $16 but also lowers the upside and commits $76 before fees. Actual prices, spreads, contract rules and taxes can change every figure; this arithmetic demonstrates the method, not a target ratio.
Run the same worksheet with the venue’s actual fee schedule and any payout adjustment. If the hedge is a different contract, add scenarios for every way the two settlement rules can diverge.
How much should you hedge?
Start with the loss you are willing to retain, then solve for a position that keeps each combined scenario inside that boundary. There is no formula that can determine the right fraction of a bankroll without your contract terms and personal limit. A smaller hedge may be appropriate when the original position is already within your limit; a larger hedge may be justified only when the residual loss remains unacceptable and the additional cost still fits the limit.
Use a residual-loss target
Let the original loss in the adverse scenario be L, the hedge’s net payoff in that scenario be H, and your permitted combined loss be B. The worksheet condition is L - H + all applicable costs ≤ B. Because H depends on the hedge price, payout and fees, solve it with actual contract values. Then test the opposite outcome: an oversized hedge can turn a favorable original outcome into a loss.
Prefer partial protection when uncertainty is high
A partial hedge leaves some original exposure while limiting the amount of new capital and mismatch risk. It can be more robust when liquidity is thin or the settlement language is difficult to compare. Re-run the worksheet after any partial exit or additional order; the new position is not protected merely because the first hedge was once sufficient.

Do not use an adverse move as a sizing signal
Adding contracts solely because the original market moved against you increases commitment at the moment your assumptions may be failing. Reassess the event, the remaining time, the available liquidity and your original limit. If the combined result no longer fits, reducing or closing can be safer than adding another position.
Match the hedge to the original risk
Similarity in wording is not equivalence. Check each of these dimensions:
- Event definition: “A candidate wins” is different from “a candidate is inaugurated,” and a threshold can differ from a categorical outcome.
- Time window: A contract covering a calendar month does not exactly offset one covering an election day or a specific reporting deadline.
- Settlement source: Two venues may rely on different official data, publication revisions or adjudication procedures.
- Outcome structure: A binary $1 payout does not offset a multi-choice or partial-payout contract in a fixed proportion.
- Units: Match contract counts and payout amounts. Ten contracts on one venue may not represent the same exposure as ten on another.
- Timing and liquidity: A hedge that settles later, trades infrequently or has a wide spread can fail to protect you when you need to exit.
Any difference creates residual or basis risk. Model the combinations explicitly and label the hedge as partial rather than assuming it is a mirror image.
Compare an opposite contract, an exit and doing nothing
Buying an opposite contract is only one way to reduce exposure. A partial or full exit may provide cleaner risk reduction because it removes the original contract instead of adding a second settlement rule. Holding cash and declining the hedge can also be the disciplined choice when prices, fees or liquidity make protection too expensive.
| Choice | What changes | Main cost or risk to test | When it can fit |
|---|---|---|---|
| Close or reduce the original position | Removes the specified contracts at the current executable price | Spread, market impact and the possibility that the fill is worse than the displayed price | The original exposure is no longer worth its remaining risk or the market is liquid enough to exit |
| Buy an opposite contract on the same event | Adds an offsetting payoff while retaining the original position | Second entry cost, fees, mismatched terms and residual exposure in every outcome | Definitions, timing and settlement source match and the combined worksheet stays within budget |
| Buy a related but different contract | May reduce a broader theme-related risk | Basis risk can dominate; the two contracts may resolve differently | Only when you can describe and tolerate the remaining mismatch |
| Make no additional trade | Leaves the original payoff unchanged | Full original downside remains, but no new fees or commitment are added | The original position already fits the limit or available hedges fail the worksheet |
Evaluate each choice on maximum combined loss, residual exposure, upfront cost, fees, contract match, realistic liquidity, collateral requirements and venue terms. A no-trade decision is not a failure of risk management.

Can you close a prediction-market position before settlement?
Where the market permits secondary trading, you can generally trade out before settlement at the then-current market price. The CFTC explains: Rather than being locked in their position, customers can trade in and out of their position prior to settlement at the current market price to lock in gains or limit losses.
That statement describes the possibility of an exit, not a guaranteed price or fill. Read the contract’s trading hours, halt rules, order types and settlement procedures.
- Open the position page and confirm the exact contract and side you intend to reduce.
- Review the current bid and ask, recent volume and available size at each price level.
- Estimate the proceeds after fees at several plausible fill prices, not only the last trade.
- Submit a size that fits the available liquidity; use the venue’s permitted order type and verify whether it can execute partially.
- Confirm the fill, remaining contracts, cash balance and any unsettled amount. A canceled or partially filled order leaves exposure in place.
If liquidity disappears, a market order can execute substantially away from the last price. A limit order controls price but may not fill before the event or a trading halt. Include both possibilities in your decision.
Liquidity is part of the hedge, not a footnote
The CFTC notes that complex event-contract frameworks may have comparatively lower liquidity. Thin liquidity can widen spreads, increase market impact and make a planned early exit impossible at the price used in your worksheet. Check depth for the size you actually need, not just a single quote. Recalculate after entering because your own order can change the available price.
Liquidity risk also affects a hedge’s timing. If the original contract and hedge trade on different venues or have different hours, one position may remain open while the other cannot be adjusted. Record those operational differences before treating the positions as offsetting.

Leverage changes the risk calculation. In its disclosure for perpetual futures, Kalshi warns that leverage amplifies gains and losses and that liquidation is not a guaranteed stop-loss; severe moves or illiquidity can produce worse execution. Those cautions apply to that perpetual-futures product and should not be generalized to every event contract.
If a proposed hedge uses margin or leverage, add collateral calls, liquidation mechanics, funding or financing charges and the possibility of forced execution to every scenario. A fully paid event contract and a leveraged perpetual are not interchangeable hedges even when their headlines appear related. If you cannot state the maximum loss under the product’s liquidation rules, do not count it as a defined hedge in your budget.
Fees, taxes and venue rules can change the result
Include all stated trading fees, settlement charges, spreads and applicable taxes in the worksheet. The CFTC specifically advises understanding fees and contract-specific rules. A hedge that appears to reduce a $20 loss can be uneconomic if entering and exiting both legs consumes most of that amount.
Check whether the venue is available in your jurisdiction, what registration or account requirements apply, how disputes are adjudicated, and which source determines settlement. Availability and rules can change. Read the current contract page and risk disclosures immediately before trading rather than relying on an old screenshot or a previous market.

The CFTC’s educational futures article describes a Kansas wheat farmer expecting 50,000 bushels who sells ten futures contracts, each representing 5,000 bushels, and later buys back ten contracts to close the hedge. The quantities illustrate matching exposure and contract units; they are not a prediction-market sizing recommendation or a retail bankroll rule. Use the example’s principle—identify the amount and direction of the risk, then match the offset—without importing its agricultural assumptions into an event contract. See the CFTC futures explanation.
A practical pre-trade and post-trade checklist
Before placing the hedge
- Have living expenses, emergency reserves and other savings needs been funded?
- Is the maximum combined loss written in dollars and below your personal ceiling?
- Do both contracts use the same event definition, time window and settlement source?
- Are payout, entry price, fees, taxes, expiration and collateral terms recorded?
- Can the intended size be entered and exited at realistic prices?
- Have you modeled every outcome, including outcomes where the hedge and original position both lose?
When entering
- Verify the market name, side, quantity and limit price on the order ticket.
- Use an order size consistent with displayed depth, and account for partial fills.
- Record the fill price and fees immediately so the worksheet reflects the actual position.
- Do not add funds merely to preserve a previous thesis or to avoid acknowledging a loss.
After entering
- Monitor contract announcements, settlement-source changes, trading halts and liquidity.
- Recalculate residual exposure after any fill, partial exit or price move.
- Keep records of entry, exit, fees and settlement for tax and dispute purposes.
- Close or reduce according to the pre-set rule rather than improvising under time pressure.
Common hedging mistakes and their fixes
- Hedging by percentage alone: A 50% hedge can mean very different dollars across contracts. Use outcome payouts and your loss limit.
- Ignoring the second position’s cost: Add entry fees, spreads and any financing or collateral requirement to every scenario.
- Assuming opposite wording means opposite payoff: Verify definitions, dates and settlement sources line by line.
- Using the last price as an executable price: Inspect the order book and model partial or worse fills.
- Forgetting the favorable outcome: A hedge reduces downside but can also give back upside or create a loss if oversized.
- Confusing leverage with protection: Liquidation can occur before your intended exit and is not a guaranteed stop.
- Adding capital after a loss: Reapply the original risk limit; do not let the first trade set a larger one.
- Leaving rules unverified: Recheck current fees, market hours, settlement procedures and jurisdictional eligibility before trading.
The decision rule
A defensible hedge is one whose combined payoff you can explain in every relevant outcome, whose event and settlement terms genuinely match the exposure you want to reduce, and whose worst-case loss and cash commitment stay below a limit set before the trade. If you cannot establish those three conditions, a smaller position, a partial exit or no additional trade is safer than adding complexity.
