Smart-money whale shorts $16.1M BTC/ETH, longs S&P and XYZ100
Nansen flagged a wallet on May 27 running $7.4M BTC and $8.7M ETH shorts at 20x on Hyperliquid, and $5.09M XYZ100 (4x) and $3.46M S&P 500 (2x) longs; a 5% rally could liquidate the crypto shorts.
On May 27, on-chain analytics firm Nansen flagged a wallet that holds heavily leveraged short positions on bitcoin and ether and long positions on two TradFi index perpetuals on Hyperliquid.
The wallet carries $7.4 million in bitcoin shorts and $8.7 million in ether shorts, both at 20x leverage. The combined committed margin on those short positions totals about $16.1 million. At 20x leverage, a roughly 5% upward move in either bitcoin or ether would reach the margin threshold that typically triggers forced liquidation on such positions.
Nansen calculated the notional exposure for the bitcoin short alone exceeds $148 million, reflecting the effect of leverage on position size relative to posted margin.
On the long side, the wallet holds a $5.09 million position in the XYZ100 perpetual at 4x leverage and a $3.46 million position in an S&P 500 perpetual at 2x leverage. Those TradFi longs show about $925,000 and $434,000 in unrealized gains respectively, for roughly $1.35 million in combined unrealized profit.
Hyperliquid is the platform hosting all four positions. The decentralized exchange offers perpetual futures on cryptocurrency and real-world asset indexes and processes more than $1 billion in daily trading volume, allowing traders to place high-leverage directional bets across asset types.
Nansen applies a “Smart Money” label to roughly 10,000 addresses drawn from a database of more than 300 million labeled wallets. Nansen’s research shows changes in Smart Money aggregate positioning are often followed by retail flows within one to seven days, making movements by flagged wallets notable for some traders.
In 2026, spot bitcoin and ether exchange-traded funds have attracted substantial inflows and some corporations have added bitcoin to corporate treasuries. The wallet’s configuration — leveraged crypto shorts alongside profitable TradFi longs — creates a clear liquidation exposure if prices of bitcoin or ether move up by about 5 percent.
