Highlights
- Abraxas Capital's combined short book on Hyperliquid has grown to over $980 million
- The position splits into 168,549 ETH ($423.7 million) and 2,771 BTC ($214 million) in short exposure
- The fund held a $353 million ETH-only short on September 8 and $783 million in combined shorts within days — this week's total nearly triples the earlier figure
- Abraxas has repeatedly bought small spot positions to partially hedge its shorts rather than closing them, a pattern consistent with a market-neutral spread trade
Abraxas Capital's short exposure on Hyperliquid has kept growing through September, and on-chain trackers now put the combined position at more than $980 million — split between a 168,549 ETH short worth roughly $423.7 million and a 2,771 BTC short worth about $214 million. The pace of the buildup is the more striking part: the fund was running a $353 million ETH short as recently as September 8, expanded to a combined $783 million within days, and has now pushed roughly $200 million further in the same direction.
What makes the position unusual isn't its size alone — plenty of funds run nine-figure derivatives books — but the way Abraxas keeps layering small spot purchases on top of a short it has shown no sign of closing. On September 8 the fund bought about $32 million of ETH in the spot market while its Hyperliquid short sat at $353 million, offsetting barely 9% of the notional exposure. That's not a hedge in any conventional sense; it reads more like a fund managing basis or funding-rate exposure between spot and perpetual markets than one making a simple directional bet against ETH or BTC.
A Pattern of Escalating, Not Reducing, Risk
Abraxas has built a reputation for exactly this kind of structure: large, opposing positions that pair short derivatives exposure against separate spot or hedge holdings, aiming to capture spread rather than direction. But the scale of the escalation this month is notable even by that standard. A short book that roughly tripled in size over about a week — while the fund simultaneously bought small amounts of the very asset it's shorting — suggests either high conviction that funding rates or basis will keep paying out, or a bet that both ETH and BTC have further to fall from current levels near $2,500 and roughly $77,000, respectively.

Hyperliquid's own infrastructure makes positions like this unusually visible. Unlike over-the-counter derivatives books at traditional prime brokers, every leg of Abraxas's short sits on a public order book, which is how on-chain analysts have been able to track the position's growth in near real time rather than waiting for a quarterly disclosure. That transparency has turned large Hyperliquid positions into their own genre of market signal — traders now watch Hyperliquid's order flow the way they once watched CME futures positioning, and a position this size, from a fund with this track record, tends to move sentiment even before it moves price.
That visibility cuts both ways. Other large Hyperliquid shorts have not fared well recently — other prominent whales on the platform have posted eight-figure losses on leveraged bets in the past month, a reminder that a fully transparent order book exposes losing positions just as clearly as winning ones. Abraxas's own history of running spread trades rather than naked directional shorts may explain why it has kept adding rather than retreating, but the fund's paper losses or gains on a $980 million book will now move by tens of millions of dollars with every percentage point ETH or BTC moves — a level of exposure that few market participants can absorb without it becoming the headline risk on their own book.
As Bitcoin.com News reported when the position was a third of its current size, Abraxas has shown no indication it plans to unwind the trade, buying ETH on dips rather than reducing the short itself. Whether that conviction holds through the next leg of ETH and BTC's price action will be one of the more closely watched positions on Hyperliquid heading into the rest of September.
