Bitcoin's recent recovery has brought it back to the estimated cash-cost line for publicly traded miners, a level that underscores the shifting economics of the industry. As of Tuesday evening, the token was trading at $75,499.64 on Coinbase, nearly matching the $75,500 weighted average ex-tax cash cost calculated by CoinShares for the second quarter. While the symmetry is notable, analysts caution that this figure is not a hard price floor, given the wide variation in power contracts, equipment efficiency, and financing across operators.
The rebound, however, does more than just improve current mining margins; it also highlights a structural transformation. According to CoinShares' latest mining report, at least 35 exahashes per second (EH/s) of computing capacity is scheduled to exit the listed-miner group, representing about 4.7% of the network's total hashrate of roughly 750 EH/s. This exodus is not easily reversible, as it involves long-term commitments that go beyond simply switching off machines.
Committed Exits and AI Pivot
Several miners have made irreversible moves. Core Scientific paid $41.9 million to cancel an order for approximately 15 EH/s of next-generation mining hardware. Keel, formerly Bitfarms, ceased mining operations on June 29. IREN aims to substantially complete its transition away from Bitcoin mining by December 31. CoinShares expects Cipher Digital to exit mining by the end of 2027, while TeraWulf is winding down its remaining 145 megawatts.
These decisions are driven by the economics of AI infrastructure versus traditional mining. CoinShares estimates that AI data centers can generate roughly $1.5 million in annual profit per megawatt, compared to about $500,000 from Bitcoin mining. Although these are modeled figures and AI projects require significantly more capital, the profit gap explains why even a sustained Bitcoin rally may not redirect already committed sites.
Hash Price Recovery and Stock Divergence
Bitcoin ended June near $58,400, well below the Q2 cash-cost estimate, while the average hash price fell to a record $27.70 per PH/s per day. The token's later recovery toward $77,000 lifted hash price to roughly $38, putting most operators back above breakeven. The Coinbase spot quote was slightly lower Tuesday evening, but the trend is clear.
For miners like MARA Holdings, Riot Platforms, CleanSpark, HIVE Digital Technologies, and Bitdeer Technologies, a sustained Bitcoin rise can still justify adding efficient mining capacity. Their equity valuations remain sensitive to hash price, energy costs, fleet efficiency, and Bitcoin holdings on their balance sheets.
In contrast, IREN, Cipher Digital, TeraWulf, and Core Scientific increasingly require a different analytical lens. Investors must now evaluate power availability, construction spending, lease counterparties, and the timeline for contracted megawatts to generate revenue. Calling them simply "Bitcoin miners" masks the divergent risk profiles that separate these stocks.
Survivors Could Benefit
For miners that stay committed to Bitcoin, there is a potential upside. If capacity leaves the network and difficulty adjusts downward, each remaining efficient unit of hashrate could earn more. New entrants might also purchase displaced machines or secure cheaper power elsewhere, potentially offsetting any lasting decline in network hashrate. The report describes a transfer of economics and infrastructure, not the end of Bitcoin mining.
The next key signal, therefore, is not just whether Bitcoin holds above $75,500, but whether hash price stays above $40 while difficulty and power costs remain contained. Equally important is whether companies promising AI revenue can convert signed capacity into operating cash flow without overstretching their balance sheets.
