Bitmain dominance and the 2026 ASIC manufacturing competition

The Era of Antminer Dominance

Bitmain controlled approximately 75% of the global Bitcoin mining machine market during the late 2010s. Founded in 2013 by Micree Zhan and Jihan Wu, the firm earned $1.1 billion in 2017 and $742.7 million in the first half of 2018. I watched as those massive profits shrank when the market slumped, leading to a $500 million loss in the third quarter of 2018 and $1 billion in unsold inventory during the second quarter of 2018. The company also lost half of its 3000 staff in late 2018. Bitmain faced $715 million in liabilities on its balance sheet as of June 2018 due to redeemable shares from its Series A and B funding rounds. The company faced significant hurdles when its Hong Kong IPO application lapsed in 2019 after investors reacted to Bitcoin price volatility. An internal governance dispute between Zhan and Wu sparked legal battles in the Cayman Islands and China, where the Beijing Haidian District Market Administration eventually ruled in Zhan’s favor. This conflict ended in 2021 when Zhan purchased Wu’s stake for $600 million, which forced the spin-off of Bitdeer and BTC.com. Why did the Hong Kong Stock Exchange reject the initial application despite such high historical profits?

A Fragmented Manufacturer Market

Competition from MicroBT and Canaan ended the total dominance of the Antminer series. While Cambridge estimated Bitmain’s market share at 82% in 2025, other reports show MicroBT at 21% and Canaan at 9%. Bitdeer now manufactures its own hardware too. High network difficulty forces miners to prioritize efficiency over raw volume. I favor manufacturers that prioritize thermal durability and energy efficiency. MicroBT’s Whatsminer series provides competitive alternatives to the Antminer. The market shifted toward diverse suppliers like MicroBT and Canaan, which reduced the market concentration that characterized the early years when Bitmain supplied nearly seventy-five percent of the world’s machines to mining operations. I would avoid manufacturers with inconsistent hardware update cycles, like Ebang, which showed a slower R&D cycle compared to MicroBT. Micree Zhan obtained a $400 million loan from Bitmain to complete the purchase of shares. You likely know that efficiency dictates survival when difficulty rises.

The 2026 Efficiency Race

Current 2026 models prioritize hydro-cooling to maintain profitability. The Bitdeer Sealminer A2 Pro Hydro produces 500 TH/s at 14.9 J/TH efficiency and yields approximately $24.07 daily at a $0.07/kWh power cost. Bitmain’s Antminer S21 XP Hydro provides 473 TH/s with 12 J/TH efficiency, earning roughly $22.24 per day under identical power conditions. For air-cooled operations, the Bitmain Antminer S21 XP provides 270 TH/s with 12 J/TH efficiency for air-cooled users, while the Bitmain Antminer S21 Pro generates 15 J/TH at 2900W.

MicroBT’s M79S reaches 930 TH/s with 13.5 J/TH efficiency, though it requires 12,555 watts. The Canaan Avalon A1566HA delivers 480 TH/s at 16.8 J/TH efficiency using 8,064 watts. I recommend the Bitdeer Sealminer A2 Pro for large-scale operations because its 500 TH/s hashrate beats the S21 XP Hydro. In 2026, hardware manufacturers like Auradine also enter the market with the Teraflux AT2880, which produces 180 TH/s at 16.0 J/TH. The Antminer S21 XP remains a smart choice if you prefer high-efficiency air-cooled miners instead of hydro units. The Antminer S21 Pro generates $9.95 in daily income at a $0.07/kWh power cost. Comparing the S19 Pro’s 29.5 J/TH efficiency against these newer models shows the performance gap.
