Summary: Perpetual futures, or perps, are futures contracts with no expiry date, kept close to the spot price by a funding rate that longs and shorts pay each other. Traders like them because they can go long or short around the clock, with leverage and no contract to roll. The main risk comes from high leverage and automatic liquidation when margin runs out. For traders who want to get funded, the alternative is CME Micro Bitcoin and Micro Ether futures, traded with a funded account at Phidias Propfirm.
Perps are hard to miss in 2026, from crypto exchanges to on-chain venues and now regulated US markets. This guide explains how they work and what they really cost. It then shows a more professional way to trade the same bitcoin and ether moves.
What are perpetual futures?
A perpetual future, also called a perpetual swap or simply a perp, is a derivative contract that tracks an asset such as bitcoin but never expires. You go long or short, post collateral called margin and keep the position open as long as that margin covers your losses and costs.
The name explains the design. A classic futures contract expires, and its price converges with the underlying asset as expiry approaches. A perp never expires, so it needs another anchor: the funding rate, a periodic payment between longs and shorts. Those recurring payments are why the product is also called a swap.
Spot is different. Buy bitcoin outright and you own the coin, with no funding and no liquidation. A perp only gives you a contract whose profit and loss follow the price, usually with leverage.
The Wikipedia entry on perpetual futures and an overview from Cornell’s SC Johnson College of Business describe these core mechanics. For a deeper side-by-side, read our guide to perps vs futures. If derivatives are new to you, start with what futures trading is.
How does the funding rate work?
The funding rate keeps a perp anchored to spot. Each venue builds a reference price from spot markets, usually called the index price. When the perp trades above it, funding is positive and longs pay shorts. When it trades below, funding turns negative and shorts pay longs. Payments are exchanged periodically, commonly every 1 to 8 hours depending on the venue.
The incentive does the work. When the perp trades at a premium, longs pay to hold and shorts get paid. Arbitrage traders sell the perp, buy spot and collect the funding, which pulls the two prices back together.
A simple example: imagine you are long a $10,000 bitcoin perp and funding is positive at 0.01% per period (a round number for illustration, not a venue quote). You pay $1 to the shorts at each funding time. With funding settled every 8 hours, that is $3 a day and $90 over 30 days, even if the price never moves. On $1,000 of margin, that $90 is 9% of your capital.
Note that funding is charged on the full position rather than on your margin, so leverage magnifies its impact. The rate can also change every period.

How do leverage and liquidation work on perps?
Perps trade on margin. You post initial margin and control a much larger position. Very high leverage is common on crypto venues. If losses push your collateral below the maintenance margin, the venue’s liquidation engine closes the position automatically.
Take that $10,000 position opened with $1,000 of margin, which is 10x leverage. A 10% move against you would wipe out the margin. In practice, liquidation comes earlier, at the maintenance level. Funding payments also drain margin, so a long hold can bring the liquidation price closer in a flat market.
Liquidations can cascade. A forced liquidation hits the market at whatever price is available. When many traders are leveraged on the same side, the first liquidations push the price into the next group’s levels, and the spiral feeds itself. Positions that looked safe moments earlier get closed near the extreme of the move.

Why are perps everywhere in 2026?
Perps grew up on crypto-native exchanges, then moved on-chain. A perp DEX is a decentralized exchange where perpetual futures trade through smart contracts, with collateral deposited from the trader’s own wallet. Funding, leverage and liquidation work much the same way.
The bigger shift happened in the United States. In late May 2026, the CFTC approved Kalshi to list BTCPERP, a bitcoin perpetual futures contract. It also gave Coinbase a no-action letter so US clients can access perps routed through Coinbase Bermuda as “foreign futures”, according to CoinDesk. CFTC Chairman Mike Selig said: “Having true perpetual contracts in the United States is a major step forward…” On September 10, 2026, Kalshi added perps on gold and silver after CFTC approval, according to CNBC.
What are the hidden costs and risks of perps trading?
The headline fee is rarely the full cost of perps trading. Watch these four risks before you size a position.
- Funding adds up. On a crowded trade, the popular side keeps paying for as long as it holds, even while the price moves its way.
- Liquidation does not wait. A brief wick can close a leveraged position at a poor price. With cross margin, the rest of your balance can be drawn in.
- Venue risk is real. On a centralized exchange, your collateral sits with the venue. On a perp DEX, you take on smart contract risk instead.
- Leverage is a temptation. When very high leverage is one click away, position size stops being a plan.

The professional alternative: CME Micro Bitcoin and Micro Ether futures
Dated futures on a regulated exchange give you bitcoin and ether exposure with no funding rate. CME Micro Bitcoin futures (MBT) represent 0.1 bitcoin, and Micro Ether futures (MET) represent 0.1 ether. Since May 29, 2026, CME Group’s cryptocurrency futures and options have traded 24/7, ending the weekend “CME gap” (CoinDesk).
These contracts expire. A dated future converges with the underlying price at expiry, so it needs no funding rate. To hold past expiry, traders roll: they close the expiring contract and reopen the position in the next contract month. Intraday traders, flat by the end of the day, rarely need to roll.
This is where Phidias Propfirm fits: MBT and MET are authorized products. An Express to Live account has a static drawdown that never trails, no consistency rule, no minimum trading days and no daily loss limit. Pass the evaluation and reach the same profit target again on the funded CASH account. The Express to Live rule is simple: the first payout converts the account to a real LIVE account.
To be transparent: Phidias evaluation and CASH accounts are simulated, and the LIVE account trades real money. Express to Live and Fundamental accounts must close positions before the end of the day, while Premium allows overnight and weekend holds. Commissions are listed on the Phidias rules page and summed up in the table below.
