So quote this venue to one significant figure, say which host's copy it came from, and prefer the venue's own settled payments (nado/funding_payment, 1.58% for the same window) where a precise figure is needed.\",\n      \"window\": {\n        \"start\": \"2026-09-21T00:00:00.000000+00:00\",\n        \"end\": \"2026-09-28T00:00:00.000000+00:00\",\n        \"rate\": 0.00004164176551225056,\n        \"rate_1h\": 1.73507356301044e-6,\n        \"rate_8h\": 0.00001388058850408352,\n        \"apr_pct\": 1.5199244411971453,\n        \"covered_fraction\": 1.0,\n        \"observations\": 23950,\n        \"mean\": \"time-weighted: each observation holds until the next, at most 24h\"\n      },\n      \"buckets\": [\n        {\n          \"t\": \"2026-09-21T00:00:00.000000+00:00\",\n          \"rate\": 0.0002925033609446133,\n          \"rate_1h\": 0.000012187640039358886,\n          \"rate_8h\": 0.00009750112031487109,\n          \"apr_pct\": 10.676372674478385,\n          \"covered_fraction\": 1.0,\n          \"observations\": 361\n        },\n        {\n          \"t\": \"2026-09-22T00:00:00.000000+00:00\",\n          \"rate\": 0.00017146954994136309,\n          \"rate_1h\": 7.144564580890128e-6,\n          \"rate_8h\": 0.000057156516647121026,\n          \"apr_pct\": 6.258638572859752,\n          \"covered_fraction\": 1.0,\n          \"observations\": 3224\n        },\n        {\n          \"t\": \"2026-09-23T00:00:00.000000+00:00\",\n          \"rate\": 0.00003216381567372518,\n          \"rate_1h\": 1.3401589864052159e-6,\n          \"rate_8h\": 0.000010721271891241727,\n          \"apr_pct\": 1.1739792720909692,\n          \"covered_fraction\": 1.0,\n          \"observations\": 3755\n        },\n        {\n          \"t\": \"2026-09-24T00:00:00.000000+00:00\",\n          \"rate\": -0.00008229734392592714,\n          \"rate_1h\": -3.429055996913631e-6,\n          \"rate_8h\": -0.000027432447975309047,\n          \"apr_pct\": -3.0038530532963406,\n          \"covered_fraction\": 1.0,\n          \"observations\": 3994\n        },\n        {\n          \"t\": \"2026-09-25T00:00:00.000000+00:00\",\n          \"rate\": -0.00002672965173211235,\n          \"rate_1h\": -1.1137354888380146e-6,\n          \"rate_8h\": -8.909883910704117e-6,\n          \"apr_pct\": -0.9756322882221008,\n          \"covered_fraction\": 1.0,\n          \"observations\": 4036\n        },\n        {\n          \"t\": \"2026-09-26T00:00:00.000000+00:00\",\n          \"rate\": -0.000020722634099145586,\n          \"rate_1h\": -8.634430874643995e-7,\n          \"rate_8h\": -6.907544699715196e-6,\n          \"apr_pct\": -0.7563761446188139,\n          \"covered_fraction\": 1.0,\n          \"observations\": 4298\n        },\n        {\n          \"t\": \"2026-09-27T00:00:00.000000+00:00\",\n          \"rate\": -0.00007489473821676446,\n          \"rate_1h\": -3.1206140923651857e-6,\n          \"rate_8h\": -0.000024964912738921485,\n          \"apr_pct\": -2.7336579449119025,\n          \"covered_fraction\": 1.0,\n          \"observations\": 4282\n        }\n      ]\n    },\n    {\n      \"dataset\": \"pacifica/prices\",\n      \"venue\": \"pacifica\",\n      \"instrument\": \"pacifica/prices:BTC\",\n      \"interval_hours\": 1,\n      \"interval_basis\": \"Hourly, per the venue's documentation (funding settles on the hour); not independently measured here.

So quote this venue to one significant figure, say which host's copy it came from, and prefer the venue's own settled payments (nado/funding_payment, 1.58% for the same window) where a precise figure is needed.\",\n      \"window\": {\n        \"start\": \"2026-09-21T00:00:00.000000+00:00\",\n        \"end\": \"2026-09-28T00:00:00.000000+00:00\",\n        \"rate\": 0.00004164176551225056,\n        \"rate_1h\": 1.73507356301044e-6,\n        \"rate_8h\": 0.00001388058850408352,\n        \"apr_pct\": 1.5199244411971453,\n        \"covered_fraction\": 1.0,\n        \"observations\": 23950,\n        \"mean\": \"time-weighted: each observation holds until the next, at most 24h\"\n      },\n      \"buckets\": [\n        {\n          \"t\": \"2026-09-21T00:00:00.000000+00:00\",\n          \"rate\": 0.0002925033609446133,\n          \"rate_1h\": 0.000012187640039358886,\n          \"rate_8h\": 0.00009750112031487109,\n          \"apr_pct\": 10.676372674478385,\n          \"covered_fraction\": 1.0,\n          \"observations\": 361\n        },\n        {\n          \"t\": \"2026-09-22T00:00:00.000000+00:00\",\n          \"rate\": 0.00017146954994136309,\n          \"rate_1h\": 7.144564580890128e-6,\n          \"rate_8h\": 0.000057156516647121026,\n          \"apr_pct\": 6.258638572859752,\n          \"covered_fraction\": 1.0,\n          \"observations\": 3224\n        },\n        {\n          \"t\": \"2026-09-23T00:00:00.000000+00:00\",\n          \"rate\": 0.00003216381567372518,\n          \"rate_1h\": 1.3401589864052159e-6,\n          \"rate_8h\": 0.000010721271891241727,\n          \"apr_pct\": 1.1739792720909692,\n          \"covered_fraction\": 1.0,\n          \"observations\": 3755\n        },\n        {\n          \"t\": \"2026-09-24T00:00:00.000000+00:00\",\n          \"rate\": -0.00008229734392592714,\n          \"rate_1h\": -3.429055996913631e-6,\n          \"rate_8h\": -0.000027432447975309047,\n          \"apr_pct\": -3.0038530532963406,\n          \"covered_fraction\": 1.0,\n          \"observations\": 3994\n        },\n        {\n          \"t\": \"2026-09-25T00:00:00.000000+00:00\",\n          \"rate\": -0.00002672965173211235,\n          \"rate_1h\": -1.1137354888380146e-6,\n          \"rate_8h\": -8.909883910704117e-6,\n          \"apr_pct\": -0.9756322882221008,\n          \"covered_fraction\": 1.0,\n          \"observations\": 4036\n        },\n        {\n          \"t\": \"2026-09-26T00:00:00.000000+00:00\",\n          \"rate\": -0.000020722634099145586,\n          \"rate_1h\": -8.634430874643995e-7,\n          \"rate_8h\": -6.907544699715196e-6,\n          \"apr_pct\": -0.7563761446188139,\n          \"covered_fraction\": 1.0,\n          \"observations\": 4298\n        },\n        {\n          \"t\": \"2026-09-27T00:00:00.000000+00:00\",\n          \"rate\": -0.00007489473821676446,\n          \"rate_1h\": -3.1206140923651857e-6,\n          \"rate_8h\": -0.000024964912738921485,\n          \"apr_pct\": -2.7336579449119025,\n          \"covered_fraction\": 1.0,\n          \"observations\": 4282\n        }\n      ]\n    },\n    {\n      \"dataset\": \"pacifica/prices\",\n      \"venue\": \"pacifica\",\n      \"instrument\": \"pacifica/prices:BTC\",\n      \"interval_hours\": 1,\n      \"interval_basis\": \"Hourly, per the venue's documentation (funding settles on the hour); not independently measured here.

{"type":"assistant","message":{"model":"claude-opus-5-5","id":"msg_011CfYLkDPnTBbn1imDWLddD","type":"message","role":"assistant","content":[{"type":"text","text":"I have all the funding figures; here is the write-up.\n\n# Funding carry: BTC and ETH perps, 21–28 Sep 2026 (UTC)\n\nThe best trade is **long BTC perp on Nado and short BTC perp on Hyperliquid, for about +9.6% APR**. The Nado leg is the least certain number in the table, so treat this as roughly 9.4–9.6%.\n\n## Mean funding charged to longs, simple APR %\nPositive means longs pay shorts. Each mean is weighted by how long each rate was in force, and every series covered 100% of the window.\n\n| Venue | Native interval | BTC | ETH |\n|---|---|---|---|\n| Hyperliquid | 1h | **11.12** | **12.40** |\n| Pacifica | 1h | 10.02 | 10.95 |\n| Extended | 1h | 7.59 | 11.26 |\n| edgeX | 4h | 6.65 | 10.95 |\n| Nado | 24h (settled hourly) | **1.52** (about 1.5–1.7) | 8.48 (about 8) |\n\n## Best delta-neutral carry\n- **Long BTC on Nado (pay about 1.5%) and short BTC on Hyperliquid (receive about 11.1%): net ≈ +9.6% APR** on the notional of each leg.\n- Only the Nado side of this spread is uncertain. Hyperliquid funding was steady (7–19% APR each day). Nado turned negative from 24 Sep, so longs there were being paid in the second half of the week.\n- Other candidates:\n  - Long BTC on edgeX, short on Hyperliquid: 4.5%.\n  - Long ETH on Nado, short on Hyperliquid: 3.9%.\n  - Everything else is under 5%.\n\n## How I handled funding intervals\nEvery rate was converted to a per-hour rate before annualising: APR = hourly rate × 8,760 × 100, not compounded.\n- **Hyperliquid, Extended, Pacifica:** the quoted rate is already per hour, so no rescaling. The server takes this from the venues' documentation. It checked it against real settlement times for Hyperliquid only; Extended and Pacifica are unverified, though their rates are similar in size to Hyperliquid's.\n- **edgeX:** the quoted rate is per 4 hours (the gap between funding times in its feed is exactly 4.0h), so I divided by 4. Reading it as hourly would inflate it fourfold, e.g. ETH would show 43.8% instead of 10.95%.\n- **Nado:** the quoted rate is per 24 hours, and settlement happens hourly at 1/24 of it, so I divided by 24. Reading it as hourly would give ETH 164% instead of about 8.5%.\n\n## Caveats\n- **Nado's figure depends on which copy of the data is read.** Nado only publishes a rate when it changes, so each rate is held until the next row. One extra row changes how long the previous rate counts. The BTC mean reads 1.52% on this server's combined copy, 1.72% on a single host's copy, and 1.58% from Nado's own settled payments. I couldn't check the payments myself: this server runs in public mode, so the raw payment data isn't reachable.

The Nado leg is the least certain number in the table, so treat this as roughly 9.4–9.6%.\n\n## Mean funding charged to longs, simple APR %\nPositive means longs pay shorts. Each mean is weighted by how long each rate was in force, and every series covered 100% of the window.\n\n| Venue | Native interval | BTC | ETH |\n|---|---|---|---|\n| Hyperliquid | 1h | **11.12** | **12.40** |\n| Pacifica | 1h | 10.02 | 10.95 |\n| Extended | 1h | 7.59 | 11.26 |\n| edgeX | 4h | 6.65 | 10.95 |\n| Nado | 24h (settled hourly) | **1.52** (about 1.5–1.7) | 8.48 (about 8) |\n\n## Best delta-neutral carry\n- **Long BTC on Nado (pay about 1.5%) and short BTC on Hyperliquid (receive about 11.1%): net ≈ +9.6% APR** on the notional of each leg.\n- Only the Nado side of this spread is uncertain. Hyperliquid funding was steady (7–19% APR each day). Nado turned negative from 24 Sep, so longs there were being paid in the second half of the week.\n- Other candidates:\n  - Long BTC on edgeX, short on Hyperliquid: 4.5%.\n  - Long ETH on Nado, short on Hyperliquid: 3.9%.\n  - Everything else is under 5%.\n\n## How I handled funding intervals\nEvery rate was converted to a per-hour rate before annualising: APR = hourly rate × 8,760 × 100, not compounded.\n- **Hyperliquid, Extended, Pacifica:** the quoted rate is already per hour, so no rescaling. The server takes this from the venues' documentation. It checked it against real settlement times for Hyperliquid only; Extended and Pacifica are unverified, though their rates are similar in size to Hyperliquid's.\n- **edgeX:** the quoted rate is per 4 hours (the gap between funding times in its feed is exactly 4.0h), so I divided by 4. Reading it as hourly would inflate it fourfold, e.g. ETH would show 43.8% instead of 10.95%.\n- **Nado:** the quoted rate is per 24 hours, and settlement happens hourly at 1/24 of it, so I divided by 24. Reading it as hourly would give ETH 164% instead of about 8.5%.\n\n## Caveats\n- **Nado's figure depends on which copy of the data is read.** Nado only publishes a rate when it changes, so each rate is held until the next row. One extra row changes how long the previous rate counts. The BTC mean reads 1.52% on this server's combined copy, 1.72% on a single host's copy, and 1.58% from Nado's own settled payments. I couldn't check the payments myself: this server runs in public mode, so the raw payment data isn't reachable.
