Bitmain is cutting prices across much of its Bitcoin mining hardware lineup as miners face shrinking margins and high operating costs.

Discounts deepen across S19 and S21 lines

According to The MinerMag and internal price lists, Bitmain has rolled out steep discounts, bundle deals, and auction-style sales on models including the Antminer S19 and S21.

Hardware pricing has reportedly fallen to about $3 to $4 per terahash (TH), levels that earlier in 2025 were typically associated with distressed sales.

Bitmain has also experimented with bidding formats that let buyers set the final price.

Bitmain wrote in a November 2025 post on X:

“Name your price and grab this batch of ANTMINER S19k Pro—final cost is up to your bid!”

Hashprice below breakeven

The discounts come as hashprice, a revenue metric for miners per unit of hashpower, has fallen to roughly $35 per petahash per day.

Many miners are said to need around $40 per petahash per day to break even, pushing some operators to shut down machines or delay expansion.

Bitmain’s factory lists show hydro and immersion models discounted as well, including S19e XP Hydro and 3U S19 XP Hydro near $3/TH, and S21 immersion units around $7/TH.

Bundled hosting and post-halving pressure

Bitmain is also bundling hosting, offering rates around 5.5 to 7 cents per kWh in locations including the U.S., Brazil, Kazakhstan, Paraguay, and Ethiopia.

The squeeze has continued after the April 2024 block subsidy halving, which cut rewards to 3.125 BTC.

Bitcoin’s price rose above $126,000 in October before falling to around $80,000 in November, while fees stayed weak, with recent blocks often generating under 0.05 BTC in total fees.
