The filing, made public on April 20, 2026, confirms that Tether acquired approximately half of the total IPO share offering when the company listed on Nasdaq in May 2025 at $12.80 per share, formalizing a non-binding interest Tether had previously disclosed to purchase up to $25 million worth of shares at the $12 per share midpoint price ahead of the listing.

The stake is valued at roughly $24 to $25 million at the IPO price, though the stock has since fallen more than 50% from its opening price.

The disclosure formalizes what was already a significant commercial relationship. Antalpha provides supply chain financing, hashrate-backed loans, and equipment financing to institutional Bitcoin miners, with supply chain loans typically denominated in USDT, Tether's stablecoin.

Tether chairman Giancarlo Devasini also appears in the same regulatory filing as a separate shareholder, meaning Tether's leadership holds Antalpha exposure at both the corporate and individual level.

Antalpha's business model sits at the center of the global mining supply chain. When an institutional miner purchases Bitmain's Antminer hardware, Antalpha is typically the institution offering the financing, often secured by the machines themselves or by Bitcoin collateral. The company originated $2.8 billion in loans during 2024, and its outstanding loan portfolio stood at $1.6 billion as of December 31, 2024. Revenue reached $47.45 million for the full year, up 321% from 2023, and the company swung to a $4.39 million net profit after posting a $6.6 million loss the prior year. First-quarter net income grew 423% year over year, a figure that sharpens the contrast between strong underlying financials and a struggling share price. Antalpha uses a capital-light structure: it earns technology financing fees on loans while a related entity called Northstar provides the underlying capital, keeping credit risk with Northstar rather than on Antalpha's balance sheet.

The Bitmain connection runs deep. Antalpha was co-founded as a sister company to Northstar under a parent entity beneficially owned by Micree Zhan, Bitmain's CEO and co-founder. Ahead of the IPO, the companies underwent a legal separation, with Northstar transferred to an irrevocable trust with Bitmain co-founder Jihan Wu as trustee. Despite the legal separation, Northstar remains Antalpha's primary funding source, and Bitmain retains a right-of-first-refusal arrangement that directs hardware customers toward Antalpha for financing. Critics and analysts have described the separation as legal rather than operational, given these enduring ties.

The result is a tightly linked triangle. Bitmain sells the machines, Antalpha finances the purchase in USDT, and Tether issues the USDT.

For Asian miners, the stakes are concrete. Antalpha's loan book is concentrated in Asia: 77.4% of its $1.6 billion portfolio, or roughly $1.26 billion, is directed at Asian institutional clients. That share has grown from 66.2% in 2023. The Americas, by contrast, fell from 24.6% of the loan book to just 6.9% over the same period. EMEA holds 15.7% of the portfolio, a figure that underscores how little of Antalpha's current business reaches Africa and clarifies that the continent's potential remains entirely forward-looking. Antalpha served approximately 75 institutional clients globally as of its IPO filing, a number that puts the concentration of a $1.6 billion portfolio in sharp relief. For miners across East and Southeast Asia seeking to upgrade hardware after the April 2024 Bitcoin halving compressed margins, Antalpha is often the only institutional-grade financing option accessible. "We are building Antalpha for the long term, with transparency, prudence and risk management at the core," said Paul Liang, Antalpha's CFO, in a May 2025 statement on the company's Tether Gold collateral arrangement.

The relationship between Tether and Antalpha has expanded well beyond equity. In May 2025, Antalpha committed to allocating up to $40 million in Tether Gold (XAUt, Tether's gold-backed token) as collateral diversification. In October 2025, Antalpha anchored $150 million in financing for Aurelion, described as the first Tether Gold treasury company to list on Nasdaq. These moves signal that the institutional mining finance layer is beginning to intersect with tokenized real-world asset infrastructure.

That ecosystem integration carries meaningful concentration risk. With Tether holding approximately half of the total IPO share offering and Northstar serving as Antalpha's primary funding source, miners using the platform carry direct exposure to Tether's financial health. The interlocking dependencies are a structural feature, not an incidental one.

The picture outside Asia is also shifting. In Africa, Ethiopia has allocated 600 megawatts of capacity to Bitcoin mining, drawing operators with electricity costs as low as $0.03 to $0.04 per kilowatt-hour from the Grand Ethiopian Renaissance Dam. BitFuFu, a Bitmain-incubated operator, is already active in the country with an 80-megawatt facility.

Tether, meanwhile, expanded its USDT footprint across sub-Saharan Africa through MiniPay, which reported 7 million phone-verified wallets as of December 2025. USDT accounts for approximately 43% of sub-Saharan Africa's crypto transaction volume, meaning the payment rails for USDT-denominated mining loans already exist at scale in the region. If Antalpha were to expand into African mining markets, its supply chain loan infrastructure would run on that foundation. In South Asia, where Pakistan is pursuing a state-backed initiative targeting 17,000 BTC mined annually using surplus power, USDT is already widely used for remittances and inflation hedging. Pakistan's Virtual Assets Bill 2026 extends formal legal protections to approximately 40 million crypto users, signaling an enabling regulatory environment for the sector. India ranks first globally for crypto adoption in TRM Labs' 2025 report, Pakistan ranks third, and Bangladesh, a major USDT remittance corridor, ranks 14th.

ANTA shares tell a more complicated story. The stock opened its first trading day at $16.38, hit a 52-week high of $27.72, then fell to around $8.51 in mid-April 2026, a decline of roughly 51% from its opening price. That divergence between strong underlying financials and a struggling share price is consistent with broader weakness in mining-sector equities, though analysts have not isolated a single cause.

Tether reported over $10 billion in net profits for 2025, holds more than 96,000 BTC (approximately $8.4 billion at recent prices), and has deployed over $20 billion across more than 120 portfolio companies. The Antalpha position is a small line in a large book, but its strategic logic points toward something larger: Tether is positioning itself as the financial substrate of Bitcoin mining infrastructure in the regions where that infrastructure is growing fastest.
