Antalpha Secures Tether as Major Shareholder with 8.2% Investment Stake
Through a 13D regulatory filing, Tether revealed its acquisition of an 8.2% ownership position in Antalpha, a Bitcoin mining financing firm, as part of its broader crypto infrastructure investment strategy.
The stablecoin issuer Tether has acquired an 8.2% ownership stake in Antalpha, positioning itself as among the firm's most significant shareholders after the company completed its initial public offering (IPO) in May 2025, based on documents filed on Monday.
According to a Schedule 13D filing submitted to the US Securities and Exchange Commission, Tether currently controls 1.95 million shares via associated entities, with Tether's chairman Giancarlo Devasini exercising shared voting and dispositive authority over these holdings.
The regulatory document further notes that Tether, along with its affiliated entities, reserves the right to adjust their stake either upward or downward based on prevailing market conditions and various other considerations.
Specializing in Bitcoin-backed lending solutions and equipment financing for mining operations, Antalpha maintains a loan portfolio valued at approximately $1.6 billion as of year-end 2024, and shares strong connections with the Bitmain ecosystem, which represents a leading provider of mining equipment.
The company's IPO last year generated approximately $49.3 million at a price point of $12.80 per share, as detailed in its prospectus documentation. Tether had earlier expressed intentions to acquire up to $25 million in shares.
For 2025, Antalpha posted revenue figures of $79.7 million, representing a 68% year-over-year increase, while net income climbed to $18.5 million, reflecting more than a threefold increase compared to the prior year.
During Monday's trading session, the company's stock price climbed approximately 7.2% to reach around $9.97 in the early hours, based on data from Google Finance.
As the entity behind Tether (USDT), which holds the position as the world's largest stablecoin measured by market capitalization, Tether commands a market cap of approximately $187 billion, accounting for roughly 58.4% of the overall stablecoin market that currently stands near $320.7 billion, based on information from DefiLlama data.
Tether expands investments across crypto infrastructure and beyond
The Antalpha investment represents part of Tether's strategic deployment of recent earnings to diversify across multiple sectors connected to digital assets, encompassing mining operations, artificial intelligence technologies, financial services platforms and tokenized asset initiatives.
Also on Monday, Kaio, a real-world asset tokenization protocol, announced that Tether had taken part in an $8 million fundraising round.
The participation of Tether reflects direct strategic alignment. USDT has become the dominant settlement layer for cross-border capital flows. KAIO provides the next layer: structured, compliant access to institutional-grade yield for USDT holders.
During March, Tether spearheaded a $50 million investment into Eight Sleep, a manufacturer of sleep-optimization products including smart mattresses and wellness systems, establishing a valuation of $1.5 billion for the company.
In February, the organization purchased a $150 million stake in Gold.com, equivalent to approximately 12% ownership, as component of an initiative to broaden accessibility to tokenized gold via its XAUt product offering.
That same month saw Tether execute a $100 million equity investment in Anchorage Digital, a federally chartered US digital asset banking institution that delivers custody, settlement and stablecoin issuance services to institutional clientele.
In July, CEO Paolo Ardoino revealed that Tether has deployed capital into more than 120 companies via its venture arm, with all such investments financed from company profits instead of stablecoin reserves.
Reports emerged earlier this month suggesting that Tether is pursuing additional capital at a $500 billion valuation, with company representatives noting that the fundraising effort might be postponed should investor demand prove insufficient.
