Tether buys 8.2% stake in Antalpha, boosts Bitcoin mining finance
Stablecoin issuer Tether (USDT) says it has taken an 8.2% stake in Bitcoin mining finance platform Antalpha, according to a US SEC Schedule 13D filing. Tether now holds 1.95 million shares via related entities, with Tether chairman Giancarlo Devasini sharing voting and dispositive power. The company also signaled it may adjust holdings over time.
Antalpha provides Bitcoin-backed lending and equipment financing to mining operators and is closely linked to the Bitmain mining hardware ecosystem. The firm reported a ~$1.6B loan portfolio at end-2024. After its 2025 IPO raised about $49.3M at $12.80 per share, Antalpha’s 2025 revenue reached $79.7M (+68% YoY) and net income rose to $18.5M (more than triple).
Tether’s Antalpha investment fits a broader strategy to deploy recent profits into crypto infrastructure and digital-asset financial services. Earlier on Monday, real-world asset tokenization protocol Kaio said Tether participated in an $8M funding round, and Tether previously backed Eight Sleep, Gold.com (via its XAUt tokenized gold product), and Anchorage Digital. Tether has also stated its venture investments are funded from profits rather than stablecoin reserves.
For traders, the Antalpha deal is a clear signal of continued capital flow into Bitcoin mining financing, with potential near-term sentiment support for USDT-linked infrastructure narratives.
Bullish
Tether taking an 8.2% stake in Antalpha is a direct example of stablecoin capital flowing into Bitcoin mining financing. Historically, when large stablecoin issuers or their principals increase exposure to crypto infrastructure (e.g., mining, custody, settlement, tokenization), it often supports market sentiment because it signals sustained demand for crypto rails and operational financing.
Short term, the filing and early trading reaction (shares up about 7% in the report) can lift confidence around the “USDT-to-infrastructure” theme. It may also attract traders to pairs and narratives tied to Bitcoin mining liquidity and financing.
Longer term, if Antalpha’s revenue growth (reported +68% YoY) and loan book scale persist, Tether’s stake could reinforce a durable pipeline between stablecoin ecosystem profits and real crypto value capture. The main risk is that announcements of portfolio adjustments can be read as exposure changes; however, the filing language suggesting possible future rebalancing is typical and is less likely to be bearish unless followed by major reductions.
