Tether (USDT), issuer of the world’s largest stablecoin, has unveiled a new class of modular Bitcoin mining systems in partnership with Canaan Inc. (CAN) and Swiss engineering firm ACME Swisstech. The hardware aims to cut costs, boost flexibility and accelerate the company’s push to become a top-tier infrastructure player in Bitcoin (BTC) mining.
Tether Unveils Modular Rigs to Scale Bitcoin Mining Dominance
29 April 2026 - 09:02 CEST
The 28 Apr announcement builds on Tether’s aggressive diversification from stablecoin profits into mining and related technologies, leveraging its massive reserves to secure and expand its Bitcoin holdings.
Modular design tackles industry pain points
Traditional rigs arrive fully assembled and sealed, locking operators into costly full-unit replacements for maintenance or upgrades. Tether’s approach decouples compute (hash boards), power and cooling components, allowing targeted swaps that reduce downtime and capital expenditure. The systems integrate the company’s open-source MiningOS software and support immersion cooling, submerging machines in dielectric fluid for superior heat management.
Immersion cooling typically delivers 20-30% better power efficiency than air-cooled setups by eliminating fan energy use and enabling safer overclocking, while also cutting noise and extending hardware life.
Ambition meets execution risks
Tether began recycling up to 15% of profits into Bitcoin accumulation and mining investments in 2023. It built stakes in Northern Data, acquired Peak Mining through affiliated entities and increased its position in Nasdaq-listed Bitdeer Technologies (BTDR) to around 21%. The company has poured billions into energy and mining projects across Latin America.
Nevertheless, setbacks indicate execution challenges involved. Tether committed $500mn to three mining centres and renewable facilities in Uruguay but shelved the project in late 2025 after two years of utility negotiations, incurring roughly $100mn in losses amid high energy tariffs. This contrasts sharply with its modular hardware strategy, which emphasizes adaptability over fixed-site megaprojects.
Competitive edge, broader implications
The modular rigs position Tether against large public miners such as Marathon Digital (MARA), Riot Platforms (RIOT) and Core Scientific, many of which rely on standardized air-cooled fleets and fixed power contracts. By controlling both hardware modularity and software layers, Tether can potentially achieve faster upgrades as chip technology evolves and respond more nimbly to energy price swings.
Profits from mining are expected to flow back into Tether’s Bitcoin treasury and USDT reserves, reinforcing the flywheel between stablecoin issuance, BTC accumulation and infrastructure ownership.
While precise efficiency metrics for the new rigs were not disclosed, the immersion-compatible design aligns with sector trends toward lower J/TH consumption and higher uptime in competitive hash rate races.
