ASIC Miner Profitability Ranker 2026
Real-time profitability ranking of hundreds of ASIC miners across 10 major algorithms. Set your electricity cost and see which miner earns the most — right now.
How the ASIC Miner Profitability Ranker Works
This ASIC profitability ranker calculates real-time earnings for all live known ASIC miners using live coin data — network difficulty, block rewards, and coin prices — sourced from Minerstat and WhatToMine. For each miner, it identifies the most profitable coin on its algorithm and computes: Daily Profit = Revenue − Electricity Cost − Pool Fee. Enter your electricity rate to see results personalised to your location and region.
Top ASIC Miner Manufacturers in 2026
The ASIC mining hardware market is dominated by a handful of key manufacturers, each producing miners for specific algorithms:
Bitmain (Antminer)
The world's largest ASIC manufacturer. Bitmain's Antminer S21 Pro (234 TH/s, 15 J/TH) and S23 (318 TH/s) are among the most efficient Bitcoin SHA-256 miners in 2026. Bitmain also makes the L9 for Scrypt (LTC/DOGE/QUAI) and KS5 Pro for KHeavyHash (Kaspa).
MicroBT (Whatsminer)
MicroBT's Whatsminer series is Bitmain's main competitor for SHA-256 Bitcoin mining. The Whatsminer M60S (186 TH/s) and M66S (298 TH/s) are widely used in large-scale Bitcoin mining operations for their reliability and competitive efficiency.
Bitdeer (SealMiner)
Bitdeer's SealMiner A4 Ultra Hydro achieves 9.4 J/TH — one of the most efficient SHA-256 Bitcoin miners ever built. Designed for industrial hydro-cooling, it sets the 2026 benchmark for Bitcoin mining efficiency.
IceRiver & Jasminer
IceRiver produces efficient KHeavyHash miners for Kaspa (KAS). Jasminer focuses on EtcHash miners for Ethereum Classic. Both are popular altcoin ASIC options with strong profitability at low electricity rates.
ASIC Efficiency: J/TH Explained
Joules per Terahash (J/TH) is the most important efficiency metric for ASIC miners — more important than raw hashrate. A lower J/TH means more hash per watt of electricity, which directly determines profitability at any given electricity rate.
| J/TH Range | Generation | Profitability @ $0.06/kWh | Example Miners |
|---|---|---|---|
| < 12 J/TH | Latest gen (2025–2026) | Very profitable | Bitdeer SealMiner A4 Ultra, Antminer S21 XP Hydro |
| 12–18 J/TH | Current gen (2026–2025) | Profitable | Antminer S21 Pro, Whatsminer M60S, M66S |
| 18–25 J/TH | Previous gen (2022–2023) | Marginal | Antminer S19j Pro+, Whatsminer M50S+ |
| 25–35 J/TH | Older gen (2020–2022) | Breakeven | Antminer S19 Pro, Whatsminer M30S+ |
| > 35 J/TH | Legacy (pre-2020) | Usually unprofitable | Antminer S17, S15, older S9 series |
Frequently Asked Questions
Which ASIC miner is most profitable for my algorithm in 2026? +
Profitability depends on electricity cost. At $0.06/kWh, efficient miners under 15 J/TH like the Antminer S21 Pro and Bitdeer SealMiner A4 rank highest. Set your electricity rate above to see personalised results.
What is J/TH efficiency in ASIC mining? +
Joules per terahash (J/TH) measures electricity used per unit of hashpower. Lower is better. Top 2026 ASICs achieve 9-15 J/TH. Older miners above 30 J/TH are rarely profitable at standard electricity rates.
How often does ASIC mining profitability change? +
Profitability changes with every Bitcoin difficulty adjustment (every ~2 weeks) and with daily BTC price movements. This ranker uses live data updated every hour to reflect current conditions.
