Is Bitcoin Mining Still Profitable in 2026?

Electricity is the primary variable cost in mining, and the profitability threshold in 2026 sits at approximately $0.07/kWh with current BTC prices and leading-gen hardware. US retail electricity averaging $0.13/kWh makes home mining deeply unprofitable. Industrial miners in Texas (curtailment contracts at $0.03-0.05/kWh), Ethiopia (hydropower at $0.02/kWh), and Paraguay (Itaipu dam power at $0.03/kWh) maintain strong margins. US data centre miners using renewable PPAs (Power Purchase Agreements) at $0.03-0.04/kWh are the most profitable operators globally.

Next-generation ASICs in 2026 achieve 17-22 J/TH efficiency (Antminer S21 Pro: 15 J/TH, Whatsminer M63S+: 14 J/TH), versus 30+ J/TH for 2020-era machines. A machine running at 15 J/TH consumes 50% less electricity per unit of hash rate than a 30 J/TH device, making hardware generation the second most important profitability variable after electricity price. Miners on 2019-2020 equipment (S17, M20 series) are operating at or below breakeven in most jurisdictions regardless of electricity cost.

Bitcoin's hash rate reached an all-time high of 820 EH/s in Q1 2026, up from 550 EH/s a year prior. The difficulty adjustment algorithm automatically increases mining difficulty every 2,016 blocks (~14 days) to maintain 10-minute block times, meaning that as more miners deploy capital, each miner's proportional share of block rewards decreases. The 49% increase in hash rate over 12 months has proportionally compressed revenue per TH/s, offsetting much of the BTC price appreciation benefit for existing miners.

Mining profitability scales directly with BTC price. At $95,000, a miner with 100 TH/s at $0.05/kWh earns approximately $450/month profit. At $150,000, the same setup earns ~$720/month — a 60% increase. The post-halving bull cycle thesis argues that BTC prices will rise faster than hash rate growth in 2025-2026, making today's new ASIC investments profitable within 9-12 months. Publicly traded miners (Marathon, Riot) have stacked BTC reserves as a secondary investment thesis alongside operational revenue.

Transaction fees represent an increasing but volatile share of miner revenue. During the April 2024 halving, fees briefly exceeded block rewards ($30M+ in fees in a single day due to Runes protocol congestion). Average daily fee revenue in 2026 is approximately $3-5M, representing 8-12% of total miner income at current prices. As block rewards continue halving over time, transaction fees must grow substantially to sustain miner economics — a transition that remains uncertain for the 2028+ halving era.

Cambridge Centre for Alternative Finance estimates 58% of global Bitcoin mining now uses renewable energy sources (up from 25% in 2019). This shift is driven by economics (renewables often cheapest electricity) rather than ESG pressure alone. US miners participating in ERCOT demand response programs in Texas earn additional revenue by curtailing operations during peak demand, effectively receiving payment for not mining — adding 5-15% to annual revenue and improving overall unit economics.

“Marathon Digital's Q4 2025 earnings report showed all-in sustaining costs of $32,000 per BTC mined, generating significant margin at $95,000+ BTC prices. Marathon has deployed 35+ EH/s of hash rate and holds over 40,000 BTC on balance sheet as a strategic reserve. Marathon's CEO Fred Thiel stated in Q4 earnings that post-halving profitability exceeded pre-halving levels due to BTC price appreciation outpacing the reward reduction.”

“CoinShares' semi-annual mining report estimated the average all-in production cost across publicly listed miners at $45,000-55,000 per BTC in H2 2025, providing approximately $40,000-50,000 margin at current prices. The report noted that the bottom quartile of miners (highest cost operations) face breakeven around $70,000, making them vulnerable to any sustained BTC price dip. CoinShares highlights Ethiopia, Paraguay, and Texas as the three lowest-cost mining jurisdictions globally.”

“Riot Platforms reported earning $17.9M in power curtailment credits in Q3 2025 from its Texas operations — equivalent to approximately 15% of its total mining revenue for the period. This hybrid model (mine when power is cheap, sell power back when prices are high) represents the frontier of institutional mining economics and demonstrates that mining profitability cannot be assessed solely on hash rate revenue.”

“Cambridge's analysis found that the 2024 halving eliminated an estimated 8-12% of the least-efficient hash rate within 90 days, as older ASIC operators were no longer profitable. This hashrate attrition briefly increased profitability for remaining miners before new hash rate deployment restored equilibrium. Cambridge projects continued consolidation toward institutional operators, with the top 20 mining companies controlling over 40% of global hash rate by 2026.”

“JPMorgan's crypto equity research team initiated coverage on five publicly traded miners with a broadly positive outlook, noting that current BTC prices provide 70-100% gross margins on electricity costs for leading operators. JPMorgan cautioned that hash rate growth could outpace BTC appreciation in H2 2026, compressing margins. The team favours Marathon and CleanSpark due to their renewable energy mix and flexible power arrangements, which provide more durable cost advantages than simple geographic low-cost electricity.”
