DN Funding Research · Methodology correction · Updated 31 October 2026
What Matters
Choose funding exposure by net cash flow, not the largest annualized number. This edition does not name a “most stable” exchange: the accessible evidence does not substantiate the previous ten-venue, 31-day ranking. A useful comparison requires matching contracts, settlement intervals, timestamps and actual payments—then subtracting execution and financing costs.
Predictable funding is not necessarily cheap funding. For an existing position, a venue change only improves the model when the funding advantage survives trading friction, financing differences and a realistic adverse-rate scenario. A positive result is not a recommendation to trade.

DN Evidence Block
Evidence reviewed: 31 October 2026. No new observation window is claimed.
- Correction: the 13 October edition described a 13 September–13 October BTC/ETH/SOL cohort and published DN-FSI scores. We could not reproduce those scores or coverage claims from the accessible article and linked rolling source pages during this review. The ranking, venue winners and historical-rate calculator presets have therefore been withdrawn pending auditable raw data. This does not establish that the original data never existed.
- Verified documentation: official Hyperliquid, Bybit and OKX documentation supports the mechanics discussed below. Documentation verification is not exchange execution testing.
- Provider-reported data: Yieldo's BTC, ETH and SOL pages are live third-party displays. Current observations and provider-labelled payment summaries are not a recovered archive of the earlier cohort and are not independently measured DN results.
- Modelled: all calculator defaults and scenario-table figures below are deliberately hypothetical, not live venue quotes, forecasts or backtest returns.
- Not measured: no new multi-venue settlement dataset, fills, order-book slippage sample, transfers or live trades were collected for this refresh.
Normalize the interval before comparing rates
Positive funding generally transfers value from longs to shorts; negative funding reverses the direction. A rate shown before settlement can still change. Do not mix an indicative next rate with a settled historical rate.
For a quoted per-period rate r and interval h hours, a simple comparable daily rate is r × 24 / h. Simple annualization is r × 24 / h × 365. Keep percentages and decimals consistent: 0.01% is 0.0001 in cash-flow multiplication.
Hypothetical normalization: 0.01% every eight hours and 0.00125% every hour both imply 0.03% a day, or 10.95% simple annualized if unchanged. That is not a promised annual return, nor an APY. It assumes every future interval repeats; compounding requires separate assumptions.
| Official source | Mechanic to check | Comparison consequence |
|---|---|---|
| Hyperliquid funding | Hourly payments; the eight-hour formula is paid at one eighth per hour. Payment uses position size × oracle price × rate. | Do not annualize an eight-hour formula as if it were the hourly payment. Do not substitute a mark-price notional for its documented oracle-price calculation. |
| Bybit funding-history API | Historical rates have settlement timestamps; interval is symbol-specific and available from instrument information. | Retrieve the correct contract and interval; paginate the history rather than assuming one response covers a month. |
| OKX funding mechanism | Default eight-hour assessments, with one-, two- and four-hour exceptions; schedules can adjust. Linear-contract funding value uses mark price. | Record interval changes and eligibility at each assessment. A fixed three-payments-per-day assumption can miscount cash flow. |
These are neutral documentation examples, not a venue ranking or a claim that any product is available to every reader. Check your jurisdiction, account entity, derivatives eligibility, contract listing and margin rules before considering a venue. Do not bypass access restrictions.
Realized funding is a ledger, not an annualized snapshot
For a linear contract, a simplified realized funding cash flow is Σ (side sign × settlement notionalᵢ × settled rateᵢ), where the cash-flow sign is −1 for a long and +1 for a short. Use the venue's actual contract valuation rule and the position held at assessment. Inverse contracts need their own coin-denominated formula and conversion record.
A fixed number of coins does not imply a fixed dollar notional when prices move. A constant-notional model also implies rebalancing, which can add costs. Match UTC boundaries, asset, quote currency, collateral and contract type. Count expected versus received settlements and disclose gaps; never treat missing data as zero funding.
For a stable-notional historical summary, sum actual settled rates over the common window. An annualized equivalent can describe that window, but must be labelled as a scaled historical figure. Your actual account ledger is stronger evidence of cash paid or received than a screen extrapolating the latest rate.
Hold, move, hedge—or reduce exposure?
| Choice | When it deserves consideration | What can defeat it |
|---|---|---|
| Hold the existing position | Expected savings are smaller than switching costs, or the planned holding period is short. | Funding turns adverse; margin headroom shrinks. |
| Move the same-side position | A conservative funding difference persists beyond break-even and the destination is operationally suitable. | Close/reopen fees, spread, slippage, basis change, delayed transfer or an unhedged gap. |
| Spot/perpetual hedge | You explicitly want to examine carry rather than outright direction. | Borrow cost, spot/perp basis, hedge mismatch, liquidation on one leg and separate collateral needs. |
| Reduce or close exposure | Risk limits or funding uncertainty dominate the expected advantage. | Exit friction remains, and reducing exposure changes the original investment thesis. |
A hedge can reduce price sensitivity without eliminating risk. Buying spot and shorting a perpetual uses capital even without borrowing; borrowing cash adds financing cost. Reverse carry can require borrowing the asset, with changing rates, availability or recall risk. Two leveraged perpetual legs still require independently adequate margin. Profits on one venue may not be transferable fast enough to protect the other.
DN Hold-or-Move: hypothetical scenario calculator
All defaults are invented examples. No live rates, historical venue presets or execution recommendations. Enter comparable simple annualized funding assumptions for the same asset and same-side linear position. Negative rates are allowed. Costs use total position notional, not deposited margin.
Interactive mode is not active in this page view. The worked example and formula below are the static fallback. Reload this article directly to try interactive mode.
Modelled output only: positive net advantage means the entered assumptions cover the entered costs—not that moving is safe or profitable. Stress tests halve or reverse the funding-rate difference while leaving financing and switching costs unchanged. The formula and worked table remain usable if your browser does not run the calculator.
The scenario model—and how quickly the advantage disappears
Let N be constant notional, d days, A and B the current and target simple funding APRs as decimals, F the target-minus-current annual financing cost, and s = +1 for a long or −1 for a short. Let C = N × total friction bps / 10,000 + fixed cost.
Net advantage of moving = N × [s × (A − B) − F] × d / 365 − C
Break-even days = C / {N × [s × (A − B) − F] / 365}, only when the daily advantage is positive. If it is zero or negative, no positive-cost funding break-even exists under those assumptions.
| Hypothetical $100,000 long, 30 days | Gross funding advantage | Extra financing | Switching cost | Net advantage |
|---|---|---|---|---|
| 10% current / 6% target | $328.77 | $82.19 | $225.00 | $21.58 |
| Difference halves: 10% / 8% | $164.38 | $82.19 | $225.00 | −$142.81 |
| Difference reverses: 6% / 10% | −$328.77 | $82.19 | $225.00 | −$635.96 |
All rows assume 20 bps friction, $25 fixed cost and 1% incremental financing. They exclude directional price P&L. Only incremental costs belong in a hold-versus-move decision; total strategy returns must additionally include all opening/closing, hedge and financing costs.
Methodology: what a defensible stability index needs
- Archive evidence: raw settled rates, UTC timestamps, exact instrument IDs, interval history, retrieval time, source URLs and a reproducible calculation script.
- Declare coverage: expected versus collected payments for each venue/asset; a common start/end; missing-data rules; and a frozen eligible cohort. A longer elapsed calendar period is not automatically a longer observed dataset.
- Separate cost from stability: report cumulative signed funding, daily variation, negative-funding share, sign flips, tail outcomes and consecutive adverse periods. Cross-asset dispersion is not time-series stability.
- Avoid false precision: 7-day versus 30-day average drift and current-versus-average differences may describe a regime, but do not prove predictable future payments. Mixing carry burden into a stability score also mixes two different objectives.
- Publish limits: liquidity, fills, borrowing, collateral returns, custody and liquidation are separate from the funding series. If an index uses weights, publish them and test ranking sensitivity.
Current status: this page is an evidence-led comparison framework, not a measured 2027 leaderboard. We have not replaced the withdrawn scores with a new backtest or extended the old window. Until the necessary dataset can be audited, naming a universal winner would be stronger than the evidence permits.
Before acting: risks the calculator cannot settle
- Execution and basis: close and reopen prices can differ; spreads widen, market depth disappears and funding changes while orders wait.
- Collateral and liquidation: stablecoins can depeg; collateral haircuts and unrealized losses reduce headroom. Lower funding does not imply lower liquidation risk.
- Transfer and venue risk: withdrawal limits, maintenance, bridge failure, network congestion, custody failures, smart-contract bugs and oracle issues can prevent timely rebalancing.
- Financing and capital: borrowing can reprice or become unavailable; idle collateral has opportunity cost; returns on margin must not be confused with returns on position notional.
- Access: product availability depends on jurisdiction and account entity. A working documentation link is not proof of eligibility or permission to use a product.
Optional platform research links—not a ranking
Affiliate disclosure: DN may earn compensation if you register or trade through the two optional links below. They are existing DN registry links, not evidence of superior funding, a fee guarantee or a recommendation to open an account. Compare the neutral documentation alternatives above first.
- Gate (affiliate) — official perpetual-futures/API documentation. Check the current agreement for your serving entity and product-specific eligibility.
- MEXC (affiliate) — official perpetual-funding documentation. Its user agreement excludes prohibited jurisdictions; a working signup link does not override those restrictions.
Product documentation was checked on 31 October 2026. Access still depends on location, account entity, verification and the specific contract. Neither link certifies that you are eligible, and neither venue is assigned a stability score in this edition.
Sources, disclosures and limitations
Official mechanics reviewed on 31 October 2026: Hyperliquid funding documentation, Bybit funding-history documentation, and OKX funding mechanism (page marked updated 28 October 2026). These explain mechanics; they do not validate the withdrawn historical rankings.
Earlier linked third-party displays rechecked for evidence context: Yieldo BTC, ETH and SOL. Their rolling content is provider-reported, not a reproducible DN archive of the original observation period.
Commercial independence: optional affiliate links are disclosed separately from neutral sources. Commercial relationships do not establish funding stability or validate the withdrawn ranking.
Risk disclosure: educational analysis, not investment advice. Funding, liquidity and contract rules can change. Perpetuals can lead to losses exceeding the funding income; hedging does not remove liquidation or counterparty risk.
