📈 Perpetual Futures
Last verified: July 2026"Perps" let traders speculate on a price with leverage, without ever owning the coin — and without a contract that ever expires. They now trade trillions of dollars in volume. Here's how they actually work.
The idea in one line
A perpetual future — a "perp" — is a contract that lets you bet on a crypto price going up or down, using borrowed leverage, without ever actually owning the coin. Unlike a traditional futures contract, it has no expiry date — you can hold the position indefinitely, as long as you keep enough margin to cover it.
The problem perps had to solve
Ordinary futures contracts settle on a fixed date, forcing traders to close out or "roll" into a new contract regularly — inconvenient friction for a market that trades 24/7. Perpetual futures, first popularised by the exchange BitMEX, removed the expiry date entirely. But that creates a new problem: without an expiry to force the price back in line, what stops the perpetual contract's price from drifting away from the real ("spot") market price of the coin?
The funding rate: how perps stay honest
The answer is the funding rate — a periodic payment (often every few hours) made directly between traders holding opposite positions, not to the exchange. When the perpetual price trades above the real spot price, it means too many people are betting the price will rise ("going long") — so longs pay a fee to shorts, making it more expensive to stay long and nudging the perp price back down. When the perp trades below spot, the payment flips: shorts pay longs, pulling the price back up. This constant back-and-forth payment, not an expiry date, is what keeps a perpetual contract anchored to reality.
Leverage — and why it cuts both ways
Perps are almost always traded with leverage: depositing a small amount of margin to control a much larger position. 10x leverage means a 10% move against you wipes out your entire margin — and positions are automatically closed ("liquidated") by the exchange before losses can exceed what you deposited. Leverage doesn't just amplify gains; it amplifies losses by exactly the same multiple, and liquidations can cascade quickly during volatile moves, which is exactly when many inexperienced traders get wiped out.
Centralised vs. decentralised perps
Perps are offered both on centralised exchanges (Binance, Bybit) and on-chain through "perp DEXs" like Hyperliquid, GMX, and dYdX, where trades, margin, and liquidations are all handled transparently by smart contracts rather than a company's internal systems. By 2026, decentralised perp trading has grown into a genuinely large share of the overall market — a notable shift from crypto derivatives being almost entirely centralised just a few years earlier.
The real risks
Perps are among the highest-risk instruments in crypto. Liquidation risk — leveraged positions can be wiped out by a move that would barely register for a spot holder. Funding cost — holding a popular side of a crowded trade for a long time means steadily paying (or, less often, earning) the funding rate, which can erode returns even if your price call is eventually right. Volatility — perps react instantly to news and can produce far sharper swings in your account value than simply holding the coin. This is a tool for people who understand leverage deeply, not a beginner's way to "invest" in crypto.
The India angle
Tax treatment of crypto derivatives in India is genuinely unclear — gains may fall under the standard 30% Virtual Digital Asset regime, or potentially under ordinary business/speculative income rules depending on how the activity is characterised. Given the leverage involved and the tax ambiguity, professional advice is strongly recommended before trading perpetuals from India.
