Key takeaways
Binance showed $38.4M of $ETH depth within 1% of the price. Three Uniswap v3 ETH/USDC pools together showed $4.5M, about 8.5x less. (TDMM measurement, 30 Sep 2026.)
A $1M ETH trade moved Binance by 2.7 bps and the largest Uniswap v3 pool by 63.2 bps before fees, about 23x more. At $100k the all-in cost was almost the same, 10.2 vs 11.3 bps.
DEX spot volume hit a record 24.2% of CEX spot volume in July 2026 ($176B vs $727B, CoinDesk Data). CEX still carries four times more spot volume.
A full-range pool needs about 100x the capital of an order book for the same 2% depth. A passive pool at new-token volatility (166%) loses about 34.4% a year to arbitrage before fees.
Most tokens that trade on both need both, run as one book with one reference price.
CEX market making is posting buy and sell limit orders on an exchange order book from one reference price. The market maker earns the spread and maker rebates and carries inventory risk and adverse selection.
DEX market making is supplying and managing liquidity in pools, price ranges, on-chain order books or proprietary AMMs. The market maker earns pool fees and pays arbitrageurs, and carries MEV, contract and stale-range risk.
Depth. On ETH, the spot books on Binance, Kraken, OKX and Coinbase were 2.7 to 8.5x as deep within 1% as three Uniswap v3 pools combined. On $LINK the gap narrowed to 1.7 to 4.0x, because DEX liquidity is split across several thin pools.

Capital. $10,000 of depth a side within 2% takes about $20,000 of resting orders, $2.01M in a full-range pool, or about $98,000 in a range of plus or minus 10% that someone keeps on the price.
Arbitrage. Loss-versus-rebalancing is volatility squared over eight a year: 2.5% at 45% volatility, 34.4% at 166%. A 0.3% pool needs about 31.5% of its value to trade every day to break even at 166%.
Rules. Binance's March 2026 guidelines ask issuers to disclose their market maker's identity and terms and ban profit-sharing and guaranteed-return deals. A DEX has no listing team, so the standard comes from your own contract.

Which one?
One DEX pool, no listing planned: managed DEX liquidity is enough
Several pools or chains: DEX market making across pools
First CEX listing onward: CEX and DEX together, on one price
