On April 23, 2026, Bitcoin's hashprice—measured by hashrateindex.com—stood at $36.46 per petahash per second (PH/s). According to data from asicminervalue.com, all 14 leading ASIC miners tracked in the current profitability ranking yield positive daily returns for operators paying $0.04 per kilowatt-hour (kWh). Net daily profits range from $12.73 to $31.62, demonstrating a rare period of widespread profitability even amid sustained network difficulty.
Top Performers in Detail
Bitmain Antminer S23 Hydro 3U tops the list with an estimated daily profit of $31.62. Released in January 2026, it delivers 1.16 PH/s at 11,020W, achieving an efficiency of about 9.5 J/TH. The unit requires three-phase power (380–415V) and is designed for water-cooling infrastructure.
MicroBT Whatsminer M79S follows with $29.91/day. Released in December 2025, it offers 1.35 PH/s at 20,000W (14.81 J/TH) and relies on dedicated liquid cooling loops.
Bitdeer Sealminer A4 Ultra Hydro, slated for May 2026, ranks third at $24.20/day. It features 886 TH/s at 8,372W with a remarkable 9.45 J/TH efficiency, designed to sustain performance at higher ambient temperatures.
Bitmain Antminer S23e Hydro 2U (April 2026) earns $23.17/day, with 865 TH/s at 8,650W (10 J/TH). Its 2U form factor enables high-density rack deployment.
Bitmain Antminer S21e XP Hydro 3U (January 2025) yields $20.56/day, running 860 TH/s at 11,180W.
MicroBT Whatsminer M79 (January 2026) brings $19.55/day at 920 TH/s and 14,500W (15.76 J/TH), making it the least efficient hydro unit in the top half.
Proto Rig by Block (September 2025) stands out as the only air-cooled machine in the top 14, earning $18.28/day. It provides 819 TH/s at 12,000W and features nine hot-swappable hashboards with sub-90-second in-rack repair time. The manufacturer also notes immersion readiness.
Bitdeer Sealminer A4 Pro Hydro (May 2026) projects $17.62/day at 680 TH/s and 7,412W (10.9 J/TH).
Bitdeer Sealminer A3 Pro Hydro (September 2025) earns $16.09/day at 660 TH/s and 8,250W (12.5 J/TH).
MicroBT Whatsminer M7DS (March 2026) nets $15.91/day at 680 TH/s and 9,200W (13.5 J/TH).
Remaining Profitable Models
Bitmain Antminer S23 Hyd (single-board, January 2026) earns $15.81/day at 580 TH/s and 5,510W (9.5 J/TH). MicroBT Whatsminer M7D (March 2026) returns $14.23/day at 634 TH/s and 9,200W (14.5 J/TH). Bitmain Antminer S21 XP+ Hydro (July 2025) yields $12.91/day at 500 TH/s and 5,500W (11 J/TH). MicroBT Whatsminer M73S+ (December 2025) rounds out the list at $12.73/day at 540 TH/s and 7,200W (13.33 J/TH).
Industry Milestones and Outlook
On April 7, 2026, Bitdeer unveiled the Sealminer A4 series, with the flagship model achieving a Bitcoin mining efficiency of 9.45 J/TH, setting a new record. Currently, favorable hashprice levels, efficient liquid-cooled rigs, and cheap electricity support miner margins. However, this window depends on volatile variables: electricity tariffs, network growth, and Bitcoin's price. Any significant shift could quickly reshape the profitability landscape. For now, modern ASIC fleets operate in a rare alignment of scale, efficiency, and timing.
