Polymarket Perps Explained: Leverage, Funding & Liquidation

What Are Polymarket Perps?

Perpetual futures are leveraged contracts that track the price of an underlying asset and never expire. Instead of resolving to $0 or $1 like a prediction-market share, a perp lets you hold a long or short position on an asset indefinitely and close it whenever you want — as long as you keep enough margin to maintain it.

Polymarket's initial perps roster is BTC, NVDA (Nvidia stock) and Gold (XAU), with more assets expected. You can go long or short with leverage of up to 10x–20x, and everything settles in pUSD on Polygon. One standout: the NVDA perp trades 24/7, so you can react to overnight earnings leaks, Asia-hours news, and weekend gaps without waiting for the stock market to open.

Leverage and Margin

Leverage lets a small amount of margin control a larger position. With 10x leverage, $1,000 of margin controls $10,000 of notional exposure — so your profit and loss is calculated on the full $10,000. A 5% move in your favor is a 50% return on margin; a 5% move against you is a 50% loss.

That amplification cuts both ways, which is why sizing and risk controls matter far more on perps than on a binary prediction market where your maximum loss is simply your stake.

Funding Rates: The Mechanism That Anchors Perps

Because perps never expire, something has to keep their price tethered to the underlying spot price. That something is the funding rate — a small payment exchanged between longs and shorts, typically every 8 hours.

• When the perp trades above spot, funding is positive and longs pay shorts.
• When the perp trades below spot, funding is negative and shorts pay longs.

Typical funding is small — around ±0.01% per 8 hours (roughly ±10% annualized) — but in volatile conditions it can spike to ±0.5% per 8h. And it compounds: a 0.05%/8h rate works out to roughly 5.5% per month. That funding stream is the foundation of the market-neutral strategies covered in our funding-rate arbitrage guide.

Mark Price vs. Index Price

Two prices matter on a perp. The index price is the underlying spot value, sourced from an oracle. The mark price is what your position is valued and liquidated against. Keeping these distinct prevents a brief wick on a single venue from unfairly liquidating traders — but it also means the mark can drift slightly from spot, which is exactly the basis edge that arbitrage bots look for.

Liquidation: The Risk That Doesn't Exist in Prediction Markets

If the market moves against you far enough that your margin is exhausted, your position is liquidated — closed automatically at a loss. Roughly speaking:

• At 10x leverage, a ~10% adverse move liquidates you.
• At 5x leverage, it takes ~20%.
• At 3x leverage, ~33%.

"Wick risk" is real: BTC has moved more than 10% within minutes, and a single wick past your liquidation price wipes the position even if price immediately recovers. Polymarket Perps have no native stop-loss beyond liquidation, so protective tooling — trailing stops, leverage caps, and live liquidation-price tracking — is essential.

How Perps Differ From Polymarket Prediction Markets

On a prediction market, you buy YES or NO shares, your downside is capped at your stake, and you wait for the event to resolve. On a perp, you take a leveraged directional position that never resolves on its own, you pay or receive funding while you hold it, and you can be liquidated. The upside is flexibility: continuous exposure, true short-selling, and a funding mechanism that creates market-neutral yield opportunities.

What This Means for Automated Trading

Funding is paid on a fixed clock, basis dislocations close in seconds, and margin must be watched 24/7 — all of which favor a bot over a human. That's the gap Perphawk fills: it monitors funding, mark and index across venues, executes funding and basis trades market-neutral, and manages liquidation risk on every position automatically.
