One Matrixport‑linked whale holds $300m in ETH and BTC longs, with $26m unrealized

A Matrixport‑linked whale holds about $300m in leveraged Ethereum and Bitcoin longs with roughly $26m in unrealized profit, concentrating risk and raising liquidation shock potential.

A highly leveraged whale is sitting on eight figures of paper profit after loading up on both Ethereum ($ETH) and Bitcoin ($BTC), underscoring how concentrated risk has become in the current market.

Whale builds $300M‑plus long book in $ETH and $BTC

On‑chain and derivatives monitoring data show a single whale address holding long positions of around 120,000 $ETH and roughly 700 $BTC across major derivatives venues. At current prices, that stack represents more than $300 million in notional exposure, with $ETH accounting for the bulk of the risk. The combined unrealized profit on these positions is estimated at close to $26 million, reflecting the strength of the latest leg in the crypto rally.

Tracking feeds attribute at least part of this activity to an address linked with Matrixport, which earlier this month was reported to be long 120,000 $ETH and 650 $BTC, worth about $306.4 million at the time, with over $22 million in unrealized profit. The increase in both $ETH and $BTC prices since that report lines up with the current higher notional and larger paper gains flagged by derivatives analytics platforms.

Double‑digit leverage and tight margins

Data from derivatives dashboards indicate the whale is using double‑digit leverage on a portion of these $ETH positions, with leverage levels around 15x on some legs and margin utilization sitting well above 100% in comparable high‑profile $ETH trades. In earlier cases, similar 15x $ETH longs reached position sizes above 25,000 $ETH and over $120 million notional, with unrealized profits in the mid‑single‑digit millions, before any meaningful de‑risking occurred. The current book, at roughly five times that $ETH size plus a sizeable $BTC leg, represents a materially larger concentration of leveraged risk.

High leverage compresses the distance between profitability and liquidation. A 15x leveraged $ETH long can see equity wiped out on a price move of just a few percent against the position, particularly when margin utilization is elevated and additional collateral is not posted. In practice, this means that relatively modest pullbacks in $ETH or $BTC could force this whale — and copycat traders following the same play — into involuntary de‑leveraging.

Market impact and trading implications

For the broader market, the presence of such a large, directional, leveraged player creates a focal point. While the whale’s current unrealized profit acts as a vote of confidence in the uptrend, it also introduces a single‑point‑of‑failure dynamic: if the trade goes against them, large liquidations could hit order books across multiple exchanges in a short window.

For professional traders, this setup argues for tighter risk controls around $ETH and $BTC perps: tracking liquidation clusters, monitoring funding for signs of stress, and using options to hedge against a sudden cascade. For retail, the takeaway is straightforward: chasing the same side as a highly leveraged whale late in the move often means inheriting their downside without their balance sheet.
