Perps vs Prediction Markets: What’s the Difference?

Perps, short for perpetual futures, and prediction markets both give you a way to trade on what happens next, but what you need to get right is different. A prediction market might ask whether Bitcoin will be above $100,000 on December 31. You can buy YES if you think it will, buy NO if you don’t, and sell the position before the market resolves if the price moves in your favor.

A Bitcoin perp works differently. You go long if you think Bitcoin’s price will rise or short if you think it will fall, and your profit or loss changes as the price moves from your entry. Perps can also use leverage, which brings margin, funding and liquidation into the trade.

With Kalshi and Polymarket both offering perps trading alongside the prediction market products, the difference between the two is significant enough that it’s worth understanding where product market fits best:

• Prediction markets: You buy YES or NO on an outcome, such as whether BTC finishes above $100,000 or the Fed cuts rates.
• Perps: You go long or short an asset’s price, usually with the option to add leverage.
• Leverage: A bigger position can magnify your return, but it also gives the market less room to move against you before your margin becomes a problem.
• Funding: This is your interest on a perp. You may pay it or receive it while the position remains open.
• Liquidation: If a leveraged perp loses enough, the position can be closed. Buying YES or NO with cash doesn’t give you a liquidation price.
• Kalshi vs Polymarket: Kalshi perps are available to eligible U.S. traders; Polymarket perps are part of the global site, not Polymarket US.

How this works with Bitcoin

Say Bitcoin is trading at $80,000 and you think it has much further to run. You find a prediction market asking whether BTC will be above $100,000 at the end of the year and buy YES. You could also take the same bullish view by opening a BTC perp and going long at $80,000.

Bitcoin could climb 20% to $96,000 and stay there through December. That’s a very good call on direction, but the YES position still loses at resolution because the question wasn’t whether Bitcoin would rise. It was whether Bitcoin would finish above $100,000. The perp, on the other hand, has moved in your favor from $80,000 to $96,000.

The opposite can happen as well. Bitcoin could fall hard after you go long, recover a few months later and eventually finish the year at $105,000. Your YES contracts could pay out, while a leveraged perp may have been liquidated during the earlier fall. You got the eventual Bitcoin price right, but the perp didn’t make it that far.

You don’t have to keep YES until the market resolves. If you bought at 45 cents and the price moves to 70 cents, you can sell and take the gain. That’s one reason prediction-market traders tend to talk about buying a side, holding a position and getting out rather than treating every trade as something that must be held until settlement.

Some views fit prediction markets better

Bitcoin makes the products look more similar than they really are because BTC already has a continuously traded price. Move to a Fed meeting and the difference is clearer. If you think the Fed cuts at its next meeting, you can simply buy YES on a market asking whether the cut happens.

There isn’t a Fed decision perp. You could go long gold, Bitcoin or Nasdaq because you think one of them will rally after a cut, but now you’re making two calls. You need to get the Fed decision right and then correctly predict how another market reacts to it.

The same thing happens around company earnings. You might buy YES on Nvidia beating a particular earnings number, or you might go long an NVDA perp because you think the shares will rally after the report. Nvidia can beat the number and still fall if guidance disappoints or traders had expected an even stronger result.

• Trading the event itself: Prediction markets usually make more sense when your view is about an election, rate decision, sports result, economic release or another outcome.
• Trading the price reaction: Perps make more sense when your view is that BTC, Nvidia, gold or another asset is simply going higher or lower.
• Trading both: You can sometimes have positions in both markets, but they aren’t making the same bet. You might get one right and lose on the other.

Why Kalshi and Polymarket make this more confusing

Prediction markets and perps used to live in fairly separate corners of trading. You went to Kalshi or Polymarket to buy YES or NO, while crypto traders went elsewhere for leveraged perpetual futures. That line has moved.

Kalshi now offers CFTC-regulated perps alongside its prediction markets, with a separate perps margin account. You will need to apply for that account before you can trade, and the money in it is kept separate from your prediction-market balance. Kalshi says a liquidation in the perps account cannot reach money held in the predictions account.

Polymarket launched its perps exchange on September 3, 2026. The global site now offers perps on crypto, individual stocks, indices and commodities, with up to 20x leverage on some markets. Those perps can use the same polymarket.com balance as prediction trades, but the product is not available through Polymarket US.

Kalshi’s current BTC documentation shows leverage of up to 6x, while its broader product can use different limits depending on the asset. Polymarket likewise varies leverage by market: for example, VIRTUAL currently allows up to 5x while HYPE allows up to 20x.

The main point isn’t which platform offers the bigger number. It’s that opening a BTC perp on either platform doesn’t put leverage on a YES position you already own. You’re opening another position with another set of rules.

Leverage changes how long you can afford to be wrong

Leverage is probably the biggest adjustment if you’re used to buying YES or NO. With a perp, the cash you put down can control a much larger position. If you put up $100 at 5x leverage, you’re taking roughly $500 of market exposure.

The upside is easy to understand: a 5% move in your favor has a much larger impact on your $100. The downside works the same way. Kalshi gives a similar example in its own material, showing that $1,000 at 5x controls $5,000 and a 10% move changes your equity by $500.

Here’s what that looks like using $100 of starting margin:

Illustrative only. This ignores trading fees, funding and liquidation rules.

This is why ‘I’ll just hold it until Bitcoin comes back’ can go wrong with a perp. Your view might cover the next six months, but the account has to survive everything that happens in between. A sharp move next week can eat enough of your margin that you don’t get to wait for the recovery.

Buying $100 of YES is different. The contracts can fall from 60 cents to 25 cents and you may eventually lose the full $100, but there’s no leverage-driven liquidation price underneath the position. You still decide whether to sell or keep holding.

Funding is a recurring perp payment

If you’re holding a perp, funding is your interest on the position. It’s the recurring payment you need to account for while the trade stays open, although unlike a normal loan you can sometimes receive funding instead of paying it.

Perps don’t expire, so funding helps keep the perp price close to the asset it tracks. Positive funding generally means longs pay shorts. Negative funding means shorts pay longs. If the rate is zero, no funding changes hands.

• Positive funding: Longs pay shorts.
• Negative funding: Shorts pay longs.
• Zero funding: Nobody pays funding for that interval.
• Longer hold: Even a small rate can start to matter when it repeats over days or weeks.

Kalshi currently settles crypto funding every eight hours, at midnight, 8 a.m. and 4 p.m. ET. Its own example uses a $5,000 position and a 0.01% funding rate, which comes to $0.50 for that funding window.

If that same 0.01% rate stayed positive for every eight-hour interval, the cost would look like this:

This is an illustration, not a forecast. Funding rates change and can turn negative, in which case a long may receive funding instead.

Trading fees are separate. Kalshi charges perps trading fees on the full notional value of the position, rather than just the margin you put down. Its help center gives the example of $50 at 5x creating a $250 position, with the fee calculated from the $250.

Kalshi perps

Kalshi’s perps are aimed at eligible U.S. traders and sit in a separate margin account from the balance used for predictions. You can move available cash between the two accounts, but money already supporting an open perp can’t be transferred out until it is released.

The standard Kalshi app currently uses isolated margin, so the collateral behind one perp is kept with that position. Kalshi Pro also offers portfolio margin, which can take offsetting positions into account.

For someone already trading Kalshi predictions, the useful summary is:

• Access: U.S.-based users who complete KYC can apply for perps access.
• Markets: Current perps include crypto plus gold and silver.
• Balance: Perps use a separate margin account from predictions.
• Leverage: Limits vary by asset; Kalshi’s current BTC documentation shows up to 6x.
• Funding: Crypto settles every eight hours; precious metals use a different schedule.
• Interest on cash: Kalshi currently pays 3.25% APY on qualifying cash held in the perps margin account.

If you already own YES on a Kalshi Bitcoin market and then open BTCPERP, you haven’t leveraged that YES position. You’ve opened a second trade.

Polymarket perps

Polymarket’s perps product is broader by asset type. The global site currently lists crypto, individual stocks, indices and commodities. Its crypto page alone lists 40 perp markets, while its index section includes products such as NAS100 and USA500.

The important geographic point is that these perps are on polymarket.com, not Polymarket US. The United States is blocked from the global platform under Polymarket’s current geographic restrictions, so U.S. users should not read the perps product as something available through the separate U.S. site.

For the global product:

• Access: Polymarket perps are not currently offered to U.S. users through Polymarket US.
• Markets: Crypto, stocks, indices and commodities are available.
• Balance: Perps use the same polymarket.com balance as prediction trades.
• Leverage: Up to 20x on some markets, with the limit varying by asset.
• Margin: Individual perp pages support isolated and cross margin.
• Collateral: Polymarket’s perp pages state that pUSD is used as collateral.

Polymarket’s perps lead has also addressed the question of leverage on event markets. The perps team is focused on continuously priced assets such as crypto and stocks; requests for leverage on markets such as political outcomes sit on the prediction-market side of the business.

Which one fits the view you’re trading?

The easiest way to choose between the two is to start with the sentence you’re trying to trade. If it sounds like an outcome that either happens or doesn’t, you’re probably closer to a prediction market. If it’s simply a view on where an asset’s price goes, a perp is usually the more direct position.

There are cases where both products can express part of the same idea. If you think Nvidia beats earnings, you could buy YES on the earnings result or go long an NVDA perp because you expect the shares to rally afterwards. Nvidia can beat the number and still fall 8%, so one trade can win while the other loses.

The risks aren’t the same

With prediction markets, you can buy the wrong side, pay too much, misunderstand how the market resolves or have trouble getting out at a good price if liquidity is thin. Your YES position can also lose most of its value long before the market settles if new information changes the odds.

Perps add leverage, funding and liquidation. A relatively small move can have a large effect on your account when you’re using high leverage, while funding can make a long hold more expensive than it first looked. The position can also be closed before the market has time to come back.

The important question isn’t just whether you think Bitcoin goes up. It’s whether you mean Bitcoin goes up from here, or Bitcoin is above a particular price on a particular date. Those sound similar until you put money on them.
