Bitcoin miner Hut 8 to increase hashrate with fleet upgrade

Hut 8 has announced an upgrade to its ASIC fleet with the purchase of 31,145 Antminer S21+ units at $15 per terahash.

North American cryptocurrency mining giant Hut 8 has unveiled plans to upgrade its ASIC fleet with the purchase of 31,145 Bitmain Antminer S21+ miners.

In a Nov. 6 press release, the Miami-headquartered mining company stated that under the purchase agreement, it will acquire the miners at $15.00 per terahash, with delivery expected in early 2025. This upgrade is set to add 3.7 exahashes per second to Hut 8’s self-mining capacity, boosting it to approximately 9.3 EH/s, a 66% increase from current levels.

The new units are expected to enhance fleet efficiency by 37%, lowering average energy consumption per terahash from 31.7 to 19.9 joules, according to the press release.

Hut 8 upgrades mining fleet

Alongside an existing option to purchase an additional 15 EH/s of Bitmain miners at its Vega site, Hut 8 stated its goal to reach around 24 EH/s in self-mining hashrate and 15.7 J/TH in fleet efficiency by mid-2025.

Hut 8 chief executive Asher Genoot noted that the S21+ offers a “faster payback period than more efficient models across a wide band of future hashprice scenarios,” adding that these machines could help the company optimize investment returns. Following the news, Hut 8 shares rose nearly 7.6% to $16.74, according to data from Nasdaq.

The upgrade comes just a few months after Hut 8 expanded its partnership with Bitmain, revealing the upcoming launch of the U3S21EXPH, a next-generation ASIC miner capable of reaching up to 860 TH/s. Scheduled for deployment in Q2 2025, the miner is the first mass-commercialized ASIC model to feature direct liquid-to-chip cooling in a U-form factor.
