Binance and Bybit Futures Arbitrage: How to Find a Setup

Binance and Bybit futures arbitrage means opening a long perpetual on the exchange where a coin is cheaper and an equal short on the exchange where it is more expensive, at the same time. You earn when the two prices converge, plus or minus the funding difference. No coins move between exchanges; you only need USDT margin on both accounts.

To find a setup, compare the prices of the same contract on both venues. Keep only those where the spread stays positive after four trading fees, funding and slippage. Below is how it works, how to filter setups and what can go wrong.

How futures arbitrage between Binance and Bybit works

Both exchanges list USDT-margined perpetual futures on hundreds of coins. The price of the same contract almost always differs slightly, because each venue has its own traders, its own liquidity and its own funding rate.

The mechanics:

• open a long on the exchange with the lower price;
• open a short for the same number of coins on the exchange with the higher price;
• the combined position is delta-neutral: a price move makes money on one leg and loses roughly the same on the other;
• when the spread narrows, close both legs and keep the difference.

You are not betting on market direction, only on the gap between venues. The big advantage over spot cross-exchange arbitrage is that nothing gets transferred. There is no risk of being stuck behind a suspended withdrawal or waiting for network confirmations.

Where the Binance–Bybit spread comes from

On BTC and ETH the gap between these two major derivatives venues is usually tiny, often hundredths of a percent, and fees eat it. Tradeable setups tend to appear elsewhere:

• mid- and small-cap altcoins, where one exchange has a noticeably thinner order book;
• fresh listings, when a contract has just launched and price discovery is still messy;
• liquidation cascades, when longs or shorts get flushed harder on one venue than the other;
• funding imbalances: when one exchange runs a high positive rate and the other sits near zero, the contract there often trades at a premium.

The practical takeaway: scanning two terminals by hand rarely works. Altcoin gaps last from minutes to a few days and show up on dozens of coins at once.

How to find a Binance–Bybit futures arbitrage setup: a step-by-step filter

A screener shows the raw spread, but the screener spread is not your profit. Run every candidate through these checks.

1. Same asset. Make sure both tickers refer to the same coin. Meme coins often trade with a multiplier (for example, a contract on 1000 units), and unrelated projects sometimes share a ticker.
2. Spread after fees. A full round trip is four taker orders: open and close on each exchange. At a taker fee of about 0.05%, that is roughly 0.2% of one leg's size. An entry spread below 0.3-0.4% is usually not worth the effort.
3. Funding on both sides. With a positive rate, shorts receive funding and longs pay it. The best setups have net funding in your favour. Compare live numbers on the Binance, Bybit, OKX and other funding rates page. Also check the interval: most contracts pay every 8 hours, but some coins settle more often, and exchanges can change it.
4. Order book depth. A last-price spread means nothing if there is no liquidity for your size. Estimate what each leg can absorb; the guide on order book depth explains how.
5. Spread stability. A one-second spike may be a data glitch or a thin book. A spread that persists and periodically narrows is more interesting.
6. Limits and leverage. On illiquid contracts, exchanges cap maximum position size and leverage.

Worked example

The numbers are illustrative and only show the logic.

Coin X: the Binance perpetual trades at $1.000 and the Bybit perpetual at $1.010, a 1% spread. Funding on Bybit is +0.03% per 8 hours (shorts receive), on Binance +0.01% (longs pay).

• Long 5,000 coins on Binance, short 5,000 on Bybit; each leg is about $5,000.
• At 3x leverage you need about $1,700 margin per exchange, plus a buffer against liquidation.
• Fees: 4 orders × $5,000 × 0.05% ≈ $10.
• Funding: receive 0.03%, pay 0.01%, net +0.02% per period ≈ $1 every 8 hours.

Say the spread narrows to 0.1% after two days:

• convergence gain: 0.9% × $5,000 ≈ $45;
• funding over 6 periods ≈ $6;
• minus $10 in fees and, say, $5 of slippage.

The result is roughly $36 on about $3,400 of margin.

The reverse can also happen: the spread widens to 2%, funding flips, and you hold longer while paying the rate. Decide in advance at what spread you exit and how long you are willing to wait.

Risks of futures arbitrage across two exchanges

The trade is delta-neutral only in total, while the margin on each exchange lives separately.

• One leg gets liquidated. In a sharp rally the Bybit short can approach liquidation while the Binance long sits on an equal profit. You cannot move margin instantly; it takes a transfer. Keep leverage low and spare USDT on both accounts.
• Different mark prices. Liquidation uses each exchange's mark price, which can differ from the last trade.
• Spread widening. The gap can move against you and stay there, especially on a coin with news.
• Funding flips. Rates reset every period, and a positive carry can turn negative.
• Delisting and ADL. One exchange may delist the contract. If the insurance fund runs short, profitable positions can be auto-deleveraged.
• Legging risk. While you open the second leg, the price can move.

Ways to reduce these risks are covered in the guide to crypto arbitrage risks.

Bottom line

Futures arbitrage between Binance and Bybit lets you trade price gaps without moving coins. What matters is not the headline spread but what is left after fees, funding and slippage.

Look for setups in altcoins, verify the contract, depth and funding on both sides, keep leverage low and set your exit beforehand. The futures arbitrage screener compares contracts across many exchanges at once, including the Binance–Bybit pair, and saves hours of manual searching.
