How Exchanges Make Money: Fees, Spreads, and Listings

The slogan on the rocket is “to the moon.” The invoice in the engine room is denominated in basis points. Understanding how exchanges earn — and it is considerable — explains a lot of exchange history, from Binance’s fee-token flywheel to the listing scandals of 2017.

1. Trading fees: the core engine

Every trade pays a percentage, typically split into maker (you add liquidity to the book) and taker (you remove it) rates. Retail spot fees run from 0.5% down to 0.1% or less on high-volume venues; Binance’s famous innovation in 2017 was letting users pay in BNB at a discount — converting every trader into a token holder with a reason to want more volume. At $100B+ of daily volume industry-wide, even 0.1% is an enormous annuity.

2. The spread: the invisible fee

“Zero-fee” brokers and simple-buy buttons earn on the spread — the gap between the price they show you and the price they actually fill. On volatile assets the spread can quietly cost 0.5–2% per round trip. It is the oldest exchange revenue stream in existence; medieval money-changers in Venice charged it too.

3. Listing fees: charging tokens to exist

Getting listed on a major exchange has historically cost token projects anywhere from nothing (the early Coinbase standard) to seven figures plus token allocations (the wild 2017–2018 altcoin era, and the documented practices at some offshore venues). Binance’s answer was to list everything fast and let volume decide; Coinbase’s was to list slowly and charge for compliance review. Both are business models; they just price risk differently.

4. Margin, futures, and interest

Derivatives now dwarf spot: perpetual futures volumes routinely run several times the spot market. Exchanges earn financing on margin loans, funding-rate spreads, and liquidation fees. On top of that, customer stablecoin balances are frequently lent out or deployed into yield — the practice that, at Celsius and BlockFi, turned an exchange-adjacent business into a bank run.

5. Custody, staking, and everything else

Institutional custody (Coinbase Custody), staking-as-a-service, card programs, launchpads, data subscriptions, market-making arms — the modern exchange is a financial department store. The through-line in every aisle: revenue scales with activity, not with your success.

The alignment problem, in one line

Your broker wants you to trade; your exchange wants you to trade more. That misalignment explains fee discounts, gamified interfaces, 100x leverage buttons, and a marketing department that prints rocket emojis. It is also why the single most useful number in this industry’s history is the fee schedule — read it before you believe the slogan.
