Tether Discloses Holding Nearly 2 Million Shares in Antalpha, a Company Linked to Bitmain

On April 20, Tether disclosed in regulatory filings submitted on Monday that it holds 1.95 million shares in Antalpha through the company’s IPO in 2025, accounting for approximately 8.2% of the shares outstanding after the IPO. Antalpha is a financial company that provides lending and financing solutions for the Bitcoin mining industry and is a key partner of Bitmain, the world’s largest cryptocurrency mining hardware manufacturer. Antalpha went public on NASDAQ in May 2025, raising about $49 million with an issuance price of $12.80 per share. Tether subscribed to more than half of the shares sold to investors in this offering, becoming one of the largest investors in the transaction at that time. Despite Antalpha’s latest financial report showing strong growth (with full-year revenue in 2025 increasing by 68% to nearly $80 million and net profit tripling to $18.5 million), its stock performance has been poor, dropping over 27% on Monday to trade at approximately $9.30 per share. Analysts believe some of the pressure comes from several Bitcoin mining companies shifting from pure mining operations to AI and high-performance computing infrastructure. This investment is the latest in a series of transactions by Tether in the fields of cryptocurrency, AI, and robotics. Recently, Tether also invested in sleep technology company Eight Sleep and participated in the strategic financing of RWA startup Kaio.
