Bitcoin Mining / ASIC

Bitcoin mining is the Proof-of-Work consensus mechanism by which new Bitcoin blocks are produced and new BTC is issued. Miners run Application-Specific Integrated Circuits (ASICs) — purpose-built chips optimized solely for the SHA-256 hashing algorithm — at massive scale, competing to find a hash that satisfies the current difficulty target. The winner earns the block reward (3.125 BTC post-April 2024 halving) plus transaction fees. Mining is capital-intensive (ASICs + power infrastructure), energy-intensive (power is the primary variable cost), and hypercompetitive (global hashrate continuously rises as miners deploy new equipment).

In 2026, the mining sector is undergoing a structural identity crisis. The April 2024 halving cut block rewards from 6.25 to 3.125 BTC, compressing margins for all miners at any given BTC price. Simultaneously, the surge in demand for GPU-based AI/HPC compute has created an alternative revenue stream for companies that own power infrastructure. The result: most major publicly-listed miners are pivoting a significant portion of their capacity to AI/HPC colocation, where they rent power and physical infrastructure to AI companies (CoreWeave, Microsoft, Google) running GPU clusters. Public miners with secured HPC contracts trade at 12.3x NTM sales vs 5.9x for pure-play BTC miners — the market is actively repricing this transition.

The ASIC manufacturing supply chain is dominated by two Chinese companies: Bitmain (Antminer, dominant) and Canaan (Avalon, #2). Bitdeer has entered ASIC manufacturing to vertically integrate. All three primary manufacturers face significant geopolitical risk given US-China tensions and potential export control exposure. MARA Holdings (66.4 EH/s, 18.6 J/TH efficiency) and Riot Platforms are the largest pure-play US public miners; Core Scientific (now majority AI/HPC), IREN, TeraWulf, Hut 8, and Cipher are the leaders in the AI pivot.

Key Claims

• Public miners could derive 70% of revenue from AI by end-2026 — Up from ~30% today; driven by HPC colocation agreements with AI hyperscalers. Evidence: weak — carried-forward claim; not present in the underlying CoinTelegraph full text verified 2026-07-22, origin unconfirmed (CoinTelegraph)
• MARA: 66.4 EH/s, 18.6 J/TH efficiency — Largest US public miner by hashrate; also holds ~38.7k BTC. Evidence: moderate (see MARA Holdings entity)
• HPC-contract miners trade at 12.3x NTM vs 5.9x pure miners — Market values HPC revenue at 2x the multiple of BTC mining revenue. Evidence: weak — carried-forward claim; not present in the underlying CoinTelegraph full text verified 2026-07-22, origin unconfirmed (CoinTelegraph)
• April 2024 halving reduced block reward to 3.125 BTC — Structurally compresses miner economics at any given price level. Evidence: strong (widely documented)
• Bitmain dominant ASIC manufacturer — Controls majority of new ASIC production globally (Antminer series). Evidence: moderate (multiple sources)
• Core Scientific: now mostly CoreWeave AI colocation — CORZ emerged from bankruptcy 2024; pivoted to AI/HPC as primary business. Evidence: moderate (multiple sources)
• Hashprice fell from ~$55/PH/s (Q3 2025) to a "structural low" near $35/PH/s — average mining cost reached ~$70,000 in Q2 2025; TheMinerMag called 2025 the "harshest margin environment of all time." Evidence: moderate (CoinTelegraph)
• Named AI/HPC pivot roster (2026): HIVE Digital (earliest mover, 2022), Core Scientific, MARA, Hut 8, Riot Platforms, TeraWulf, IREN, CleanSpark — TeraWulf recently secured Google as a 14% shareholder. Evidence: moderate (CoinTelegraph)
• MARA, Riot, Hut 8, CleanSpark rank in the top 10 corporate BTC holders — public miners are simultaneously major BTC treasuries, amplifying balance-sheet volatility in drawdowns. Evidence: moderate (CoinTelegraph)
• Galaxy Digital flags an accelerating 2024–2026 M&A/consolidation wave among weaker mining operators facing margin pressure. Evidence: weak (single forward view, cited secondhand) (CoinTelegraph)

Open Questions

• What share of public miner capacity will remain mining vs transition to AI/HPC by 2027?
• Can Bitdeer's self-manufactured ASICs compete with Bitmain at scale?
• What happens to global Bitcoin hashrate if most public miners exit or scale back mining?
• How does US geopolitical pressure on China affect ASIC supply chains?
• What is the actual current AI-revenue share for the sector, and what is the true HPC-vs-pure-miner valuation multiple? (The 70%-by-end-2026 and 12.3x/5.9x figures could not be re-verified against full-text CoinTelegraph on 2026-07-22 — needs a fresh primary source.)
