| # Hyperliquid Open Interest, Mark and Oracle Prices |
|
|
| Hourly open interest, mark price and oracle price for every Hyperliquid perp from 20 May 2023 to 31 October 2026: 5,938,268 rows across 553 markets, 235 native perps and 318 HIP-3 builder markets on `xyz`, `para`, `hyna`, `km`, `cash`, `flx`, `vntl`, `io`, `mkts` and `abcd`. |
|
|
| Total open interest grew from under $2 million across 28 markets in June 2023 to a peak of $18.35 billion at 04:00 UTC on 23 September 2026, and stood at $14.91 billion at the end of October 2026, $4.14 billion of it on HIP-3 markets. BTC peaked at $5.06 billion on 23 May 2025, ETH at $5.69 billion on 24 August 2025 and HYPE at $2.23 billion on 27 August 2026. |
|
|
| Hyperliquid's API only gives the current value; the history is in Hyperliquid's public archive as daily minute files, which leave out HIP-3 markets. This set joins that archive (until 2 August 2026) with [Ironflow](https://ironflow.sh/?utm_source=huggingface)'s own poller, which reads every market about every 10 seconds (since 3 August 2026), and keeps the last value of each hour. |
|
|
| ## Get live data |
|
|
| Live Hyperliquid data is on [Ironflow](https://ironflow.sh/?utm_source=huggingface). For data newer than this snapshot, use Ironflow's API: [`GET /v1/open-interest`](https://docs.ironflow.sh/api-reference/market-data/list-open-interest) and [`GET /v1/mark-prices`](https://docs.ironflow.sh/api-reference/market-data/list-mark-prices). No key is needed for the last 24 hours; a [free key](https://ironflow.sh/key) gives 14 days. |
|
|
| ## Source and updates |
|
|
| - **Source:** Hyperliquid's public archive (daily minute files) until 2 August 2026, then Ironflow's own poller, which reads every market about every 10 seconds. The last value of each hour is kept. |
| - **Checks:** compared with Hyperliquid's archive at the end of each hour on 15 October 2026 (see Notes). |
| - **Updates:** monthly. From the next release, each new month appears 90 days after it closes, under CC BY-NC 4.0; files published before 10 November 2026 stay CC BY 4.0. For anything newer, use the API. |
| - **Coverage:** 20 May 2023 to 31 October 2026. HIP-3 open interest from 29 April 2026, HIP-3 mark and oracle prices from 3 August 2026. |
|
|
| ## Files |
|
|
| One Parquet file per month (UTC): `data/YYYY-MM.parquet`, one row per market per hour. |
|
|
| | Column | Type | Meaning | |
| |---|---|---| |
| | `timestamp` | timestamp (UTC) | start of the hour; values are the last reading in that hour | |
| | `market` | string | Ironflow market symbol, e.g. `BTC-PERP`, `xyz:NVDA-PERP` | |
| | `coin` | string | Hyperliquid's name for the market, e.g. `BTC`, `xyz:NVDA` | |
| | `dex` | string | HIP-3 builder dex (`xyz`, `para`, ...); empty for native perps | |
| | `mark_price` | float | Hyperliquid's mark price; null where there is no reading (see Notes) | |
| | `oracle_price` | float | the oracle price Hyperliquid uses for funding; null where there is no reading | |
| | `open_interest` | float | open interest in units of the base asset, as Hyperliquid reports it | |
| | `open_interest_usd` | float | `open_interest * mark_price`; null when the mark price is | |
|
|
| ## Use |
|
|
| ```python |
| import pandas as pd |
| |
| x = pd.read_parquet("hf://datasets/ironflow/hyperliquid-open-interest/data/") |
| total = x.groupby("timestamp").open_interest_usd.sum() / 1e9 |
| print(total.resample("W").last().tail()) # total open interest, $ billions |
| ``` |
|
|
| ```sql |
| -- DuckDB: biggest 24-hour open interest increases in October 2026 |
| WITH h AS ( |
| SELECT market, timestamp, open_interest_usd AS oi, |
| lag(open_interest_usd, 24) OVER (PARTITION BY market ORDER BY timestamp) AS oi_24h_ago |
| FROM 'data/2026-10.parquet' |
| ) |
| SELECT market, timestamp, oi_24h_ago / 1e6 AS before_m, oi / 1e6 AS after_m |
| FROM h WHERE oi_24h_ago > 1e6 |
| ORDER BY oi / oi_24h_ago DESC |
| LIMIT 10; |
| ``` |
|
|
| ## Notes |
|
|
| - **HIP-3 markets:** open interest starts on 29 April 2026, mark and oracle prices on 3 August 2026, because Hyperliquid's archive has no HIP-3 rows. HIP-3 oracle prices are complete from 9 September 2026. This accounts for nearly all of the 478,305 rows without a mark price. |
| - **301 hours have no rows at all**, on 85 evenings between 11 August and 14 December 2024, 1 to 9 hours at a time. Hyperliquid's own archive files for those days end early (11 August 2024 stops at 18:31 UTC), so no public source has them. |
| - Oracle prices are also missing for native perps in a few stretches: some hours in September 2023 and May 2024, and parts of 8 July, 8 to 10 August, 27 and 30 August and 8 September 2026. 718,493 rows have no oracle price; 192 have no open interest. |
| - Checked against Hyperliquid's archive at the end of each hour on 15 October 2026 for BTC, ETH, HYPE, SOL, DOGE and ZEC: open interest matches to a median of 0.007%, mark and oracle prices to a median of 0.05% (the two sources sample a few seconds apart). |
| - No duplicate (market, timestamp) rows. Delisted markets are kept up to their last reading. |
