Bitcoin Miners Defy 'Death Spiral' Theory Amidst Halving Volatility

The 'death spiral' theory suggests that when Bitcoin's block reward is halved, miners will shut down due to reduced profitability. However, in reality, mining operates as a massive energy enterprise, and miners must continue to mine to avoid defaulting on electricity contracts.

CleanSpark and Marathon Digital, two prominent miners, have shown resilience despite the recent halving. CleanSpark produced 593 BTC in August 2026 with an operational hashrate of 50 EH/s. This contradicts the 'death spiral' theory that mining becomes unprofitable after a halving.

A comparison of the two companies' financials reveals different profiles. CleanSpark traded at $11.98 with a market cap of $3.08 billion, while Marathon Digital traded at $11.26 with a market cap of $4.35 billion. CleanSpark's debt-to-equity ratio was 234.7%, whereas Marathon's was 148.5%. Analysts have set target prices for both companies: $24.00 for CleanSpark and $14.99 for Marathon.

CleanSpark's efficiency and energy costs are crucial to its survival. The company reported a peak efficiency of 16.07 J/Th for its deployed fleet as of August 31, 2026. Its average operating hashrate was 38.3 EH/s, with total Bitcoin holdings reaching 13,703.
