Market Making: Internal Desk vs. External Providers
Should a new exchange run its own market-making desk or lease liquidity from external providers? The trade-offs on control, margin, capital, and risk — and the hybrid most venues land on.
Every new venue faces the cold-start liquidity problem: no traders without liquidity, no liquidity without traders. How you solve it — build a market-making desk or lease liquidity from outside — shapes your margins, your capital needs, and your risk. Here's the decision.
Two ways to source liquidity
| Internal desk (build) | External providers (lease) | |
|---|---|---|
| Control | You set spreads and priorities | Provider-driven |
| Margin | You capture it | You pay it away |
| Capital | You fund inventory & risk | Lower upfront |
| Speed | Slower to stand up | Fast to plug in |
| Expertise | You build it | You rent it |
Internal market making — your own or an affiliated desk quoting on your venue — gives control external arrangements can't: you decide spreads and priority pairs, and you capture the margin instead of paying it out (Dappfort). External liquidity providers supply capital and quotes as an intermediary, getting you liquid fast without building a trading operation (Openware).
The hybrid most venues actually run
In practice, mid-sized exchanges land on a blend: internal making on the top 3–5 pairs, external providers or aggregation for everything else (Dappfort). You control margins where volume concentrates (BTC, ETH, your native token) and rent breadth everywhere else. A common rule of thumb: running your own desk on core pairs tends to make economic sense within 12–18 months of launch, once volume justifies the operation.
What it means for the P&L
Liquidity isn't just an operational choice — it's a revenue one. The spread and maker-taker economics you pay external MMs come straight out of the trading-fee revenue that is your business. Early on, paying for depth is worth it; at scale, capturing it yourself on core pairs can materially improve margin.
Whichever route, real depth is also your best defence against needing to fake volume — see market surveillance & wash trading.
What operators should decide
- Open with leased liquidity so day-one users see real depth.
- Identify your core pairs and plan to bring making in-house there as volume grows.
- Check the platform supports both — internal MM tools and external LP/aggregation integration — during vendor due diligence.
The takeaway
Lease liquidity to launch with depth, build an internal desk on your core pairs as volume justifies it, and expect to run a hybrid in between. The right split protects your margins where they matter most without starving a young venue of the liquidity it needs to grow.
General guidance; the right liquidity mix depends on your pairs, volume, and capital. Not financial advice.
