Market making vs funding arbitrage: two different trading jobs
Market making tries to earn from providing liquidity while managing inventory. Funding arbitrage tries to capture carry with a hedge. Both can use perpetual futures, but they have different operating requirements and neither is risk-free.
Where the proposed return comes from
A market maker posts liquidity and manages what happens when one side fills before the other. The quoted spread is a potential gross opportunity, not guaranteed income. Adverse selection, inventory moves, fees and exit costs can consume it.
A funding trade holds a position that receives periodic payments and offsets some price exposure with another leg. The hedge might be spot against a perpetual, or opposing perpetual positions on different venues. A positive displayed rate is not a promise that it stays positive.
For the mechanism, see the official Hyperliquid funding explanation: payments depend on which side is paying and the settlement rules. Other venues can use different intervals and calculations. Always verify the market you intend to trade.
The practical differences
The strategies overlap in their need for reliable execution, but their core measurements are not interchangeable. A system can be good at discovering funding differences without implementing the order-management loop of a market maker.
| Question | Market making | Funding arbitrage |
|---|---|---|
| Primary opportunity | Provide liquidity and manage fills | Capture funding carry after hedge costs |
| Position pattern | Inventory changes with fills | Offsetting legs may remain open across settlements |
| Key operating problem | Quote placement, adverse fills and exits | Maintain the hedge and margin on every leg |
| Important costs | Fees, execution PnL, funding if exposed | Entry/exit fees, basis changes, borrow and funding |
| Useful measurements | Net PnL, CPM, exposure and fill quality | Net carry, hedge error, basis and margin headroom |
| Main misconception | Every captured spread becomes profit | Delta-neutral means risk-free |
Holding time and capital have different jobs
A market maker may aim for short inventory periods, but a thin or moving book can prevent the intended exit. A funding position generally needs to exist at the relevant settlement times; entry and exit costs must be recovered over the holding window.
Neither design makes leverage harmless. With a cross-venue hedge, a gain on one account may not supply margin quickly enough to protect the losing account. With market making, repeated one-sided fills can accumulate exposure even while the interface continues to quote.
Evaluate position size, collateral and venue rules before comparing advertised returns. The inventory-risk guide covers market-making exposure; the delta-neutral guide explains the funding workflow.
A hypothetical funding route after costs
Suppose an illustrative $10,000 hedged position receives $4 per day of net funding before transaction and operating costs. If entering and closing both legs costs $12 in total, three unchanged days would only cover that cost. A funding reversal or an extra $5 of basis loss changes the result immediately.
This is arithmetic, not a live route or return forecast. It assumes equal notionals, unchanged payment rates and a working hedge; real execution can violate all three. Borrow costs, collateral opportunity cost and venue-specific fees may add further costs.
Annualising the first day's rate hides those assumptions. Record actual settlements and all entry and exit fills. Do not substitute a scanner's current rate for the rate the account actually received.
Which SypherScore tool fits which question?
For a hosted market-making workflow, start with Vesper and its mode-specific guides. EXITE is publicly documented for Entropy; read its gate, limits and charges rather than treating it as a generic funding bot.
For funding research, use the scanner overview, the funding table and the backtesting guide. These help investigate candidates and history; a research screen is not proof that a route can be executed at the displayed economics.
For order-book and asset context, the Arcus dashboard guide explains the available market views. Inspect liquidity on the actual instrument, not just the venue's headline activity.
Choose by the failure mode you can manage
If you want to work on quote quality and repeated inventory cycles, evaluate market making. If you want to research carry and maintain hedged positions through funding settlements, evaluate funding arbitrage. If you cannot explain the exit and failure procedure, keep researching before using capital.
Both need cost accounting and independent position checks. Funding can reverse, hedges can drift, APIs can fail and counterparties can become unavailable. A scanner, bot or backtest cannot remove those risks.

Questions
Is market making the same as funding arbitrage?
No. Market making focuses on liquidity provision and inventory management; funding arbitrage focuses on carry from a hedged position. Execution and risk controls matter to both.
Does delta-neutral mean risk-free?
No. A hedge can reduce some price exposure while leaving basis, funding, liquidation, margin-transfer, liquidity and venue risks.
Can I use a funding scanner as a market-making bot?
A scanner researches rates and candidates. It does not by itself implement quote placement, cancellation, inventory management or exits.
Where should I start on SypherScore?
Use Vesper's guides for hosted market-making modes. Use the funding scanner and backtesting guides for funding-route research.
