Bitcoin's recovery since mid-August has created a clear divide in cryptocurrency market performance. Bitcoin itself has risen approximately 22% since August 17, but mining companies have largely failed to keep pace.
According to a September 9 analysis by The Block, Canaan is the only major mining company outperforming Bitcoin during this period. The other 10 tracked miners have delivered a median return of just 1.8%, trailing Bitcoin's gains by 20.2 percentage points. This translates to miners capturing only 8.2% of Bitcoin's upside, a significant gap for investors who previously viewed miners as leveraged plays on Bitcoin price movements.
AI Ambitions Create Performance Headwinds
Core Scientific and TeraWulf have emerged as the largest underperformers, lagging Bitcoin by 27% and 24% respectively. Both companies are heavily focused on artificial intelligence and high-performance computing ventures. According to S&P Global Market Intelligence estimates, HPC is projected to represent around 71% of revenues in 2026 for Core Scientific and IREN, and 70% at TeraWulf.
The pivot toward AI carries distinct risks. Financing these buildouts requires substantial capital without significant dilution or costly debt, according to Compass Point analyst Michael Donovan. In late July, crypto stocks focused on mining faced headwinds despite gains elsewhere in the sector.
Mining Economics Remain Challenged
Even as mining fundamentals improved in August, they remain well below historical norms. Bitcoin's price rose 24.5% in August while the USD hash price increased 24.4%, climbing from $31.63 to $39.33 per PH/s/day, according to Luxor's August Hashrate Lookback.
However, the August average hash price of $34.63 remains 32% below the 2025 monthly average of $50.68. Transaction fees represented only 0.70% of block rewards, marking the 14th consecutive month that fees failed to exceed 1% of total rewards.
Forward-looking futures contracts offer little optimism. Luxor's averaged contracts for September through February show a projected hash price of $36.98, approximately 27% below the 2025 average. Miners would benefit from higher transaction fees, reduced network difficulty, or lower power costs to meaningfully improve margins.
Exchanges and Stablecoin Issuers Build Resilience
Exchanges and stablecoin firms have outperformed because they generate revenue from multiple sources independent of Bitcoin production. Coinbase reported that 88% of Q2 net revenue came from sources outside Bitcoin spot trading, with its crypto trading market share reaching 10.3%. Average USDC holdings across its products reached $20 billion.
Circle reported $73.3 billion in USDC in circulation at the end of Q2, up 19% year over year, alongside $701 million in total revenue and reserve income.
Miners are attempting their own diversification strategies. CoinShares estimated more than $70 billion in cumulative AI and HPC contracts across public miners, with operators potentially generating as much as 70% of revenue from AI by year-end. Recent acquisitions include Marathon's $1.5 billion purchase of Long Ridge and IREN's $3.4 billion NVIDIA cloud contract.
The divergence reflects a broader market shift: capital is increasingly rewarding businesses that monetize trading, stablecoins, and settlement infrastructure while treating mining as a capital-intensive commodity business carrying execution risks.
