A Hyperliquid whale holds a $38 million short position against Bitcoin. But does this trade matter for the broader market?
Hyperliquid Whale’s $38M Short Position: What We Know
Data from CoinGlass shows the whale, linked to the address 0x7fda…c517d1 (also known as BobbyBigSize), has maintained a large bearish bet on Bitcoin and several altcoins. The position has generated $159 million in profits over the past seven months.

However, the account has lost $561,000 in the last 30 days. This suggests the strategy may be losing effectiveness.
Arkham data previously connected this address to Fasanara Capital, a London-based asset manager. The company manages over $5 billion in total assets. Fasanara Digital, its crypto arm, launched in 2018 and oversees $400 million across market-neutral strategies and venture investments. Another $150 million is managed through a quantitative multi-manager approach.

The specific crypto trading strategy behind the fund remains unclear.
Bitcoin Price Action and Market Context
Bitcoin struggled to hold above $78,000 on Friday. The asset has gained 29% since hitting a yearly low of $60,100 on Feb. 6.
Many analysts view this as a bullish setup. They point to the strong recovery from the February low as evidence of underlying demand.
But the whale’s bearish positioning adds a note of caution. The trader’s current portfolio shows a $38 million short on BTC and multiple altcoins. At the same time, BobbyBigSize opened a $21 million leveraged long position on Ether last week. This indicates short-term confidence in ETH but a bearish view on the broader market.
Funding Rates Signal Unusual Bearish Demand
Funding rates on major exchanges provide additional context. On Hyperliquid, funding rates for BTC and ETH are slightly positive. This indicates moderate demand for leveraged long positions.
But on Binance and Bybit, funding rates are negative. This is unusual given Bitcoin’s recent price gains. Negative funding rates mean short sellers are paying longs to maintain their positions. It signals unusually high demand for bearish apply.
Industry watchers note that this divergence is rare. It suggests that professional traders on centralized exchanges are betting against further upside.
The implication is clear: the market is not universally bullish despite the price recovery.
BobbyBigSize: A Whale with a Track Record
BobbyBigSize is not an ordinary retail trader. The account has executed over $11 billion in trades on Hyperliquid using algorithmic strategies.
Key statistics from Hyperdash data:
- Current deposited assets: $19.4 million
- Win rate: 63% of trades are profitable
- Average trade duration: Slightly over two weeks
- Median position length: Less than four days
The whale excelled during the market crash between October and November 2025. During that period, BobbyBigSize placed leveraged short bets on Ether, Hyperliquid, Avalanche, and Fartcoin. Those trades generated significant profits.
But the recent losses show that no strategy works forever. Algorithmic traders are erratic and unpredictable.
Does the Whale’s Position Matter for Bitcoin?
The short answer: it depends on the timeframe. A single whale’s position is unlikely to move a $1.7 trillion market like Bitcoin. But the alignment with broader funding rate data is worth noting.
What this means for investors is that a retest of the $75,000 level remains possible. The whale’s bearish positioning, combined with negative funding rates on major exchanges, creates a headwind for further upside.
But the whale has also been wrong recently. The $561,000 loss over the past month suggests the market is not following the same pattern as late 2025.
Bitcoin traders should watch for a daily close above $80,000 to confirm the bullish trend. A failure to break that level could lead to a pullback toward $75,000.
Ether Shows a Different Story
BobbyBigSize’s $21 million long on Ether adds complexity to the picture. The whale is bearish on Bitcoin but bullish on Ethereum. This suggests a belief that ETH will outperform BTC in the near term.
This is not a new trade. The whale has used algorithmic trading to open short-duration long positions in Bitcoin and Solana in the past. The approach is opportunistic rather than directional.
The implication is that the whale is trading relative value rather than absolute market direction. This makes the $38 million short less of a pure bearish signal.
Conclusion
The Hyperliquid whale’s $38 million short position against Bitcoin is notable but not definitive. The alignment with negative funding rates on Binance and Bybit suggests caution. But the whale’s recent losses and the mixed positioning on Ether indicate that the market remains uncertain.
Bitcoin traders should not ignore the possibility of a retest of $75,000. But the overall setup remains bullish. The 29% gain since February shows strong underlying demand.
The key takeaway: watch funding rates and price action at key levels. A single whale’s trade is not a market signal on its own.
FAQs
Q1: What is a Hyperliquid whale?
A Hyperliquid whale is a trader or entity holding a large position on the Hyperliquid decentralized exchange. The term refers to the size of the trade, not the trader’s identity.
Q2: How does a $38M short position affect Bitcoin’s price?
A single $38 million short is unlikely to move Bitcoin’s price significantly. Bitcoin’s daily trading volume often exceeds $20 billion. But the position can influence market sentiment if other traders follow the same strategy.
Q3: What are funding rates in crypto trading?
Funding rates are periodic payments between long and short traders on perpetual futures contracts. Positive rates mean longs pay shorts. Negative rates mean shorts pay longs. They indicate the balance of bullish and bearish tap into in the market.
Q4: Who is Fasanara Capital?
Fasanara Capital is a London-based asset manager with over $5 billion in assets. Its crypto division, Fasanara Digital, manages $400 million across market-neutral strategies and venture investments. The firm was linked to the BobbyBigSize address by Arkham data.
Q5: Should I follow whale trades for my own strategy?
No. Whale trades can provide market context but are not reliable signals for retail traders. The BobbyBigSize account has lost money recently, showing that even successful strategies can fail. Always do your own research.
