A trader who pocketed $192 million selling BTC before last week’s crypto wipeout has reloaded with a large bearish position as markets try to recover from the Trump tariff shock.
The wallet, identified as 0xb317 on decentralized derivatives platform Hyperliquid, opened a new $163 million short position in Bitcoin on Sunday evening, according to data from Hypurrscan. The position comes with 10x leverage and is already generating $3.5 million in profit in the Asian afternoon with a liquidation level of $125,500.
The same trader first gained attention Friday when he opened a massive short sale about 30 minutes before former President Donald Trump’s surprise announcement of 100% tariffs on Chinese imports — a move that wiped out more than $19 billion in crypto market value and triggered the market’s biggest-ever day of selloffs.
The perfectly timed bet led to a nearly $200 million win, sparking speculation that the entity may have had advance knowledge of the policy change.
Analysts and on-chain traders have since dubbed the address an “insider whale.” Some even claim that this position itself could have accelerated the crash.
🚨 This hyperliquid whale opened the shorts just 30 minutes before Trump announced 100% tariffs on China. It closed the trades for a profit of $192 million. These accounts were opened today and he has already withdrawn most of the money.
Lucky whale or insider?

What is hyperfluid and why it matters
Hyperliquide is the largest decentralized perpetual exchange that allows traders to open highly leveraged futures positions directly on-chain, without relying on centralized intermediaries like Binance or OKX.
It has become a favorite among high-frequency traders and whales due to its deep liquidity, transparent order book, and lightning-fast execution, making it one of the few DeFi platforms capable of handling institutional-sized flows.
The platform also offers automatic deleveraging (ADL), or a built-in safety mechanism that prevents bad debts during extreme volatility. When insurance funds are exhausted, the ADL forcibly closes profitable positions to cover losses from failed accounts. This ensures solvency, but it can also worsen sales, as profitable traders are liquidated to balance the system.
According to HyperTracker data, more than 6,000 wallets were hit in the chase triggered by ADL this weekend, wiping out more than $1.2 billion in trading capital on Hyperliquid alone.
The new shorts add intrigue to an already tense market as participants continue to assess contagion effects after the weekend slide.
