Big trades

$5.5 million evaporated on a single leveraged Ethereum long

One account sold 12,742 Ethereum perps in one minute at an average of $1,977.65, against an inferred entry near $2,410.19. The loss was $5,511,495.

One Hyperliquid account realized a loss of $5,511,495 on its EthereumETH-2.91% perp long. It was the largest realized loss in one market among the accounts we screened. It took one minute and 1,175 fills: between 8:09am and 8:10am ET, the account sold a Ethereum perp long worth $25.2 million. That exit alone came to 2.0% of all Ethereum perp trading on Hyperliquid in the last 24 hours.

Ethereum's own day: the perp is 1.6% lower since midnight ET, at $2,016.50. The day's Ethereum news we found came from YAHOO! at 12:20am ET, before the exit began: "Ethlabs Wants Ethereum Quantum and AI Ready by 2027, Drops Its Faster Blocks Push." Nothing in the public record says why this account sold, and this story does not guess.

The account, 0x6046…b21d, sold 12,742 ETH at an average of $1,977.65. Hyperliquid does not publish its entry, but the loss puts the average near $2,410.19, a 17.9% fall against it. The long was already open at midnight ET, so its entry predates today's record.

What else the wallet did

Elsewhere it closed BitcoinBTC-3.83% perps worth $38.8 million for a loss of $5.25 million.

Hyperliquid's daily perps result for the whole account was a $2.66 million loss. That figure includes changes in the value of open positions.

Its perps account has nothing open now. $474,000 sits in spot USDC+0.01%. Its perps month stands at a $17.6 million loss.

What's next for the asset

The level to watch is the inferred entry. The perp is still 16.3% below it, so a long opened at that average is under water until Ethereum gets back past it.

On a $10,000 long at 10x, the same 17.9% fall is more than the $1,000 of margin behind it. At the 25x venue cap, a model using only the initial margin puts liquidation about a 2.0% fall from entry. The account’s collateral and margin mode determine its own threshold. Today's range, 3.5%, was wider than that.

The largest accounts in ETH lean short, the other way from this account: 60.2% of their dollars, $498.5 million against $329.9 million. At the current rate longs pay shorts 5.4% a year, or $1.47 a day on a $10,000 position.

Open interest in the ETH perp stands at $10.27 billion across the 39 venues listing it, 43.2% lower than a day earlier where the record is complete. That is a net figure across every venue, and one account's exit on one venue does not explain it.

How this was reported. Figures are OptimistFi's own check of Hyperliquid's public endpoints at 4:12pm ET on 2026-11-12. OptimistFi ranked leaderboard accounts down at least $1 million and selected up to 12 for review. Of 27 qualifying, it read fill histories for 12 and summed realized profit or loss by market from midnight Eastern time. The loss is the closed profit Hyperliquid reports on the account's ETH closing fills, and the average entry is inferred from those fills rather than read directly. The whole-day figure is Hyperliquid's perps-only day, which includes open positions marked to market. The share of trading compares the exit with Hyperliquid's own 24-hour volume in the perp. The $10,000 example is arithmetic on the same move at the leverage stated, not a trade we observed. Open interest is a net figure across the 39 venues listing ETH, while the account's $25.2 million of closing is one account on one venue, so the first is not explained by the second. Liquidation distance is computed from Hyperliquid's maintenance requirement, which is half the initial margin at the cap. News is the day's report we could find and cite, or none; it is never given as the reason for the trade. The account is identified by its address only, and no reason for the trade is given because the public record holds none.

How perps work
  • A perp (perpetual future) is a contract that tracks a price with no expiry date, so a trader can hold a bet that it rises (long) or falls (short) for as long as they like.
  • Funding is a small payment between the two sides on a schedule (every hour on some venues, every eight hours on others): when the perp trades above the price it tracks, longs pay shorts, and when it trades below, shorts pay longs.
  • Open interest is the value of all positions still open. Every long has a short on the other side, so it is one net figure, not a count of buyers or sellers.
  • Leverage lets a trader control a position larger than their deposit, up to a cap the venue sets for each market, such as 20x.
  • Liquidation is the venue closing all or part of a position when the equity supporting it falls below the required maintenance margin. The trigger depends on the venue's rules, collateral, other positions sharing that collateral, fees and funding. A leverage setting alone does not determine the liquidation price.
  • What the price follows is the venue's choice: each venue decides which index or contract its perp tracks, so two venues' "oil" or "gold" perps can follow different things.
