Bitcoin's Biggest On Chain Short Seller Boosts Bet to $125 Million

According to Arzdigital, in a report published Friday, August 14, 2026 (23 Mordad 1405), data from on chain analytics platform Lookonchain shows that an anonymous trader known as bitcoin's biggest on chain short seller has increased their leveraged bearish position to 2,000 bitcoin, worth more than 125 million dollars. The same data shows the trader currently holds about 1.79 million dollars in unrealized profit, but the position's liquidation price is set at 63,528 dollars, uncomfortably close to the current market price.\n\nBitcoin's attempt to break above 65,000 dollars earlier this week failed. Arzdigital reported that CryptoQuant analysts cited a Coinbase premium index that has stayed negative for three straight months, falling inflows into spot bitcoin ETFs, and thinner trading volume on centralized exchanges as reasons for bitcoin's inability to sustain a rally. According to Sahmino's own pricing data, bitcoin was trading around 62,880 dollars on Friday, down almost one percent on the day.
