Key takeaways
- Skew above/below outcomes can match a particular price condition at a particular expiry.
- A perpetual position's result changes with the size of the price move and the position's costs.
- A fully paid outcome purchase can lose its full cost; a perpetual can be liquidated when its margin is insufficient.
Compare the mechanics
| Dimension | Skew outcome purchase | Perpetual future |
|---|---|---|
| Primary exposure | Whether a specified price condition holds at expiry | Price movement over the time the position is open |
| Time | A specified contract expiry | No fixed contract expiry |
| Ordinary winning result | $1 per winning share, regardless of how far beyond the strike | Gain or loss changes with the price move and position size |
| Capital and loss | Pay for the shares; the purchase cost and fees can be lost | Post margin; equity changes with the position and costs |
| Funding | No periodic perpetual funding payment for holding the outcome shares | Periodic funding transfers; a position may pay or receive |
| Liquidation | No margin liquidation of a fully paid share purchase | Can occur when account equity falls below required maintenance margin |
| Early exit | Requires available liquidity and execution | Requires available liquidity and execution |
| Additional rules | Price source, averaging window, equality and void resolution | Venue-specific mark price, margin, funding and liquidation rules |
The same bullish view can lead to different exposures
Consider the hypothetical view “Bitcoin will be above $80,000 at Friday's expiry.” An above-strike outcome isolates that final condition. A Yes share pays the same $1 whether the computed settlement price is $80,100 or $90,000, assuming ordinary resolution.
A long perpetual expresses continuing upward price exposure. Its result depends on entry and exit prices, position size and costs, including funding. An adverse move before Friday can affect available margin and may trigger liquidation before the final price thesis has time to play out.
Neither instrument makes the price view more likely to be right. An outcome can lose even after an earlier rally if its final condition fails. A perpetual introduces different holding and margin decisions. This comparison does not establish that either has a higher expected return.
Choose the exposure before choosing the product
- For a final yes/no price condition, compare listed outcome strikes, expiries, costs and settlement rules.
- For ongoing exposure to the size of a price move, investigate instruments whose payoff keeps changing with price, including their margin risks.
- For actual asset ownership without a contract expiry, a binary outcome is not a substitute.
- For a touch at any point before expiry, do not substitute an expiry-only condition.

Skew publishes this comparison about its own product. It compares documented mechanics of a fully paid Skew share purchase and a margined perpetual position, using Hyperliquid's documentation for funding and liquidation. It is not an independent product review, execution test or fee ranking; costs depend on the actual trade and venue.
