Hyperliquid Liquidations

Every liquidation on Hyperliquid perpetuals from 25 May 2025 to 31 October 2026: 2,848,413 liquidated positions across 468 markets and 506,880 wallets, $58.7 billion in liquidated notional. Native perps and HIP-3 builder markets (stocks, commodities, indices) are both included. The busiest day is the 10 October 2025 crash: 109,790 liquidations, $7.2 billion.

Most of this history is no longer available from Hyperliquid's own API, which returns only a wallet's most recent 2,000 fills (10,000 by time range). The wallet behind the two largest liquidations of 10 October 2025 ($204.7M ETH and $197.2M BTC, $1.3 billion across four markets in under three minutes) reaches back only to August 2026 there.

The data comes from Ironflow, which runs its own Hyperliquid nodes and reads the liquidation field Hyperliquid puts on every liquidation fill. It is not a heuristic: each row is a fill Hyperliquid itself marked as a liquidation. Months before November 2025 were replayed from Hyperliquid's node archive on S3 and checked hour by hour against the archive files.

For data newer than this snapshot, the same rows are on Ironflow's API: GET /v1/liquidations for history and GET /v1/liquidations/stream for a live push. No key is needed for the last 24 hours; a free key gives 30 days.

Files

Two tables, one Parquet file per month (UTC):

Config	Path	One row per
events (default)	data/events/YYYY-MM.parquet	liquidated position: all fills of one wallet in one market in one block
fills	data/fills/YYYY-MM.parquet	liquidation fill, as Hyperliquid recorded it

A liquidation usually closes in a few fills (2.8 on average); a large one can take hundreds. Use events to count and size liquidations, fills for execution detail.

events

Column	Type	Meaning
timestamp	timestamp (ms, UTC)	time of the first fill
market	string	Ironflow market symbol, e.g. BTC-PERP, xyz:NVDA-PERP
issuer	string	HIP-3 builder (xyz, flx, ...); empty for native perps
wallet	string	the liquidated wallet
position_side	string	long or short: the position that was liquidated
size	float	total size closed, in base units
notional_usd	float	sum of price x size over the fills
avg_price	float	size-weighted average fill price
fills	int	number of fills
block	int	Hyperliquid block; null before 27 July 2025 (see Notes)
tx_hash	string	hash of one of the fills

fills

Column	Type	Meaning
timestamp	timestamp (ms, UTC)	fill time
market, issuer, base_market	string	market symbol, HIP-3 builder, symbol without the builder prefix
wallet	string	the liquidated wallet
side	string	side of the liquidated wallet's closing fill: sell closes a long, buy closes a short
price, size, notional_usd	float	fill price, size and price x size
block, tx_hash	int, string	Hyperliquid block (null before 27 July 2025) and fill hash

Use

import pandas as pd

events = pd.read_parquet("hf://datasets/ironflow/hyperliquid-liquidations/data/events/")
daily = events.groupby([events.timestamp.dt.date, "position_side"]).notional_usd.sum().unstack()
print(daily.tail())

-- DuckDB: the 10 largest liquidations
SELECT timestamp, market, position_side, round(notional_usd) AS usd, wallet
FROM 'data/events/*.parquet'
ORDER BY notional_usd DESC
LIMIT 10;

Notes

• Only the liquidated wallet's fills are included. The counterparty's fill carries the same liquidation field on Hyperliquid; it is dropped so each liquidation counts once.
• A few spot markets appear too (104 fills, about $0.75M): spot positions closed by portfolio-margin liquidations.
• Prices and sizes are floats as Hyperliquid reports them; notional is in the market's quote asset, USD-denominated (USDC) for every market here.
• Wallet addresses are public on-chain data.
• Before 27 July 2025 08:50 UTC Hyperliquid's archive stores fills without block numbers, so block is null there and an event groups one wallet's fills in one market at one block timestamp (every fill of a block shares it). The archive has no fills between 08:45:48 and 08:50:10 UTC that day, and the first file starts on 25 May 2025 at 14:00 UTC.
• The snapshot is refreshed periodically; for anything after 31 October 2026 use the API.
• Wallet addresses in this dataset come from public Hyperliquid data. To object to, or ask us to remove, a wallet address, write to hello@ironflow.sh. Versions already published cannot be recalled; future versions identify wallets by a pseudonymous id.

Changes

• v3, 1 November 2026. Starts on 25 May 2025 instead of 1 November 2025 (Hyperliquid's archive reaches back that far) and runs to 31 October 2026: 2,848,413 events against v2's 2,167,823, including the 10 October 2025 crash. The months already in v2 are unchanged, row for row. Daily trade counts of the replayed months match Hyperliquid's own candles within 0.5% (10 October 2025 has 0.4 to 1.5% more, all in the 20:00 to 24:00 UTC window of the cascade). 12 randomly sampled events from the new months, two per month, match Hyperliquid's userFillsByTime exactly.
• v2, 31 October 2026. We reconciled our fills against Hyperliquid's own candles, hour by hour over the 12 months, and refilled the hours that node incidents had left short (largest on 29 April, 18 to 22 May and 1 to 7 June 2026) from Hyperliquid's S3 archive. v2 has 37,269 more liquidations than v1 (2,167,823 against 2,130,554); 29 April 2026 went from 888 to 6,088 events. 24 randomly sampled events, two per month, match Hyperliquid's userFillsByTime exactly. The window now starts on 1 November 2025.
• v1, 30 October 2026. First release.
