BlockBeats news, on April 20, Tether disclosed in regulatory documents submitted on Monday that it holds 1.95 million shares of the company through Antalpha's initial public offering (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 approximately $49 million, with an issue 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.

Although Antalpha's latest financial report shows strong growth (full-year revenue growth of 68% to nearly $80 million in 2025, and net profit tripling to $18.5 million), its stock performance has been poor, dropping over 27% on Monday with a trading price of about $9.30 per share. Analysts believe that 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 crypto, AI, and robotics. Recently, Tether also invested in sleep technology company Eight Sleep and participated in the strategic financing of the RWA startup Kaio.
