Tether Takes 8.2% Stake in Antalpha, Expanding Mining Financing Ties

Tether has disclosed an 8.2% stake in Antalpha, acquiring about 1.95 million Antalpha shares through related entities. The position, disclosed in a Schedule 13D filed with the U.S. Securities and Exchange Commission, places the stablecoin issuer among Antalpha’s largest shareholders following the mining-focused lender’s May 2025 initial public offering. Giancarlo Devasini, Tether’s chairman, shares voting and dispositive power over the stake, according to the filing. The document also notes that Tether and its affiliates may adjust their holdings over time in response to market conditions and other factors.

Antalpha operates in the Bitcoin-backed lending and equipment-financing space, catering to mining operators. The company reported a loan portfolio of about $1.6 billion as of the end of 2024 and maintains close ties to the Bitmain ecosystem, a major supplier of mining hardware.

Antalpha raised roughly $49.3 million in its IPO, at $12.80 per share. Tether had previously signaled a potential interest in purchasing up to $25 million worth of shares.

In its latest annual figures, Antalpha posted 2025 revenue of $79.7 million, up 68% year over year, with net income rising to $18.5 million—more than triple the previous year’s figure. On the day of the disclosure, Antalpha’s stock climbed about 7.2% to around $9.97 in early trading, according to Google Finance data.

Antalpha and the mining-finance niche

Antalpha’s business model emphasizes liquidity and equipment financing for mining operators, a space that has drawn interest from investors seeking exposure to the cyclical upswing of crypto mining. The company’s sizable loan portfolio signals a continued focus on securing scalable credit lines for operators navigating equipment cycles and capital expenditure needs. Its connection to Bitmain’s ecosystem underscores a strategic alignment with a major supplier in the mining hardware sector, potentially easing access to hardware and related financing channels for clients.

Tether’s stake: governance, strategy, and potential impacts

The Schedule 13D filing confirms that Tether’s stake in Antalpha is substantial enough to position the company as a major shareholder. With Devasini listed as sharing voting and dispositive power, the arrangement signals an intentional governance role in Antalpha’s ongoing development. While the filing notes that Tether and its affiliates may adjust their position over time, the move reflects a broader pattern of Tether diversifying beyond its core stablecoin operations into strategic investments across crypto finance, infrastructure, and real-world asset initiatives.

Cointelegraph has previously reported on Tether’s expansive capital deployment—an approach that taps profits from USDT to fund ventures across mining, AI, financial services, and tokenized assets. The recent Antalpha stake complements a portfolio that has included investments in tokenized real assets and regulated financial infrastructure. The company’s strategy has included selective allocations to fintech and on-chain finance ventures, with profits fueling these bets rather than reserve-backed liquidity alone.

Tether’s broader venture footprint and what it signals

Beyond Antalpha, Tether’s investment activity this year has spanned several notable deals. In March, the company led a $50 million funding round for Eight Sleep, a firm building sleep-focused wellness hardware and software, which valued the company at around $1.5 billion. In February, Tether acquired a roughly $150 million stake in Gold.com, representing about 12% ownership, as part of its push to widen access to tokenized gold through its XAUt stablecoin product. In the same month, Tether announced a $100 million equity investment in Anchorage Digital, a federally chartered U.S. digital asset bank that provides custody, settlement, and stablecoin issuance services to institutional clients.

CEO Paolo Ardoino has publicly highlighted the breadth of Tether’s venture exposure, noting that the firm has invested in more than 120 companies through its venture arm, with funding drawn from profits rather than from stablecoin reserves. This approach aims to diversify the company’s revenue streams and digital-asset ecosystem exposure while maintaining a cautious stance toward custodial and regulatory-compliant ventures.

Earlier this month, reports surfaced that Tether could pursue fresh capital at a valuation around $500 billion, with the company signaling that fundraising could be delayed if investor appetite does not materialize. The stake in Antalpha, along with the broader lineup of strategic bets, reinforces a narrative of continuous expansion into crypto infrastructure and related industries—an approach that aligns with Tether’s long-term ambition to anchor a broader ecosystem around stablecoins and on-chain finance.

Market context and what to watch next

Antalpha’s performance, combined with Tether’s growing investment footprint, offers a window into how stablecoin issuers are recalibrating their role in the crypto economy—from liquidity providers to strategic accelerators for on-chain assets, mining finance, and tokenized real-world assets. For investors, the key questions revolve around governance outcomes, the impact on Antalpha’s strategy and profitability, and how Tether’s venture portfolio may influence regulatory and market perceptions of stability-backed capital in crypto markets.

As the crypto landscape evolves, observers will watch how Tether’s stake translates into governance influence at Antalpha, how Antalpha leverages this partnership to scale its lending and financing operations, and how the broader set of Tether-backed ventures interacts with growth in mining, asset tokenization, and institutional-grade on-chain infrastructure.

Readers should stay attentive to Antalpha’s quarterly results and any subsequent regulatory disclosures that illuminate how such strategic holdings shape governance, risk, and value creation in the mining-finance niche and beyond.
