Bitcoin Mining Companies Report Widening Q1 Losses as AI Data Center Shift Accelerates

In early May 2026, several publicly listed North American Bitcoin mining companies released their Q1 earnings reports, revealing a broad set of losses across the sector: Hut 8 reported a net loss of $253 million, Core Scientific posted a $347 million loss, and Riot Platforms recorded a quarterly loss exceeding $500 million.

In parallel with these earnings releases, Hut 8 shares surged more than 35% in a single trading session, while Core Scientific’s AI hosting revenue surpassed its self-mining revenue for the first time. These divergent market reactions reflect an ongoing structural revaluation of the industry, where Bitcoin miners appear to be increasingly shifting toward AI data center infrastructure as a core growth vector.

Breaking Down Q1 Results: A Sector-Wide Earnings Snapshot

Loss overview across key miners

In Q1 2026, several major listed Bitcoin mining companies reported net losses:

Hut 8 posted a net loss of $253.1 million, compared with $134.3 million in the same period last year. The primary driver was unrealized losses on digital assets totaling $295.7 million, recorded under fair value accounting rules. Quarterly revenue reached $71.02 million, up approximately 226% year-over-year, though below analyst expectations of $79.39 million. During the same period, Hut 8 announced the Beacon Point AI data center lease agreement, a 15-year contract valued at approximately $9.8 billion, covering 352 MW of IT capacity.

Core Scientific reported a net loss of $347.2 million, compared with a net profit of $57.63 million a year earlier. Revenue increased to $115.2 million, while gross profit rose from $8.2 million to $30.1 million. The loss was largely driven by $266.5 million in non-cash impairment charges and $30.8 million in fair value losses related to warrants and contingent value instruments. Self-mining revenue declined 55% year-over-year from $67.2 million to $30.1 million, while AI hosting revenue rose from $8.6 million to $77.5 million, an increase of more than eight times, surpassing mining revenue for the first time. The company also signed a 12-year hosting agreement with CoreWeave valued at over $10 billion and completed a $3.3 billion project bond issuance at a 7.75% coupon rate.

American Bitcoin, co-founded with involvement from Eric Trump, reported a net loss of $81.8 million, widening from $59.5 million in the prior quarter. The company recorded $117.18 million in non-cash impairment losses on digital asset holdings. Mining revenue totaled approximately $62.1 million, down from $78.3 million in the previous quarter. Management noted that despite a 22% decline in Bitcoin prices during the period, the company maintained a 52% gross margin, with mining costs improving from approximately $46,900 in Q4 2025 to $36,200.

Cipher Mining reported a net loss of $114.3 million, compared with $39 million a year earlier. Revenue declined approximately 28.8% to $34.84 million. The results were impacted by planned facility shutdowns at the Black Pearl site, lower electricity contract valuations, and higher interest expenses linked to new debt financing.

Riot Platforms reported a GAAP net loss of approximately $500 million, compared with $296.4 million in the prior year. Total revenue reached $167 million, including $33.2 million from AI data center operations. Losses were primarily driven by non-cash mark-to-market adjustments.

Understanding "Paper Losses": The Role of Non-Cash Accounting Items

A significant portion of reported losses across the sector is concentrated in non-cash accounting adjustments.

The first driver is unrealized losses on digital assets. Under the FASB fair value accounting standard (ASU 2023-08), companies must mark Bitcoin holdings to market each reporting period. If the market value falls below cost at quarter-end, losses must be recognized in the income statement, even without asset sales. For Hut 8, approximately $295.7 million of its reported loss was attributable to this mechanism.

The second driver is non-cash impairment charges. Mining rigs, data centers, and related infrastructure may trigger impairment tests when market conditions change, resulting in accounting write-downs. For Core Scientific, approximately $266.5 million of its loss was related to impairment expenses.

While these items do not involve immediate cash outflows, they significantly increase earnings volatility and can distort short-term profitability metrics.

The Accounting Multiplier Effect: FASB Fair Value Impact

The U.S. Financial Accounting Standards Board introduced ASU 2023-08, requiring digital assets to be measured at fair value with changes recognized in net income each reporting period. The rule became effective for calendar-year reporting entities beginning in 2025.

This framework has materially increased reported earnings volatility across the industry. A notable reference point is Strategy (formerly MicroStrategy), which holds 818,334 BTC at an average cost of $75,537. In Q1 2026, the company recorded $14.46 billion in unrealized losses due to Bitcoin price fluctuations, resulting in a reported net loss of $12.54 billion.

Although Bitcoin prices later recovered from approximately $68,000 following a quarterly low near $87,000 earlier in the period, the accounting treatment ensured that temporary price movements had an immediate impact on reported earnings.

For mining companies, this accounting regime improves transparency but also amplifies short-term volatility. As a result, investors increasingly focus on operational metrics rather than headline net income.

Several operational trends stand out:

American Bitcoin reduced mining costs from approximately $46,900 to $36,200 per Bitcoin while maintaining a 52% gross margin, suggesting efficiency improvements. Core Scientific expanded AI hosting revenue more than eightfold, indicating a structural shift in revenue composition. Hut 8 reported 226% year-over-year revenue growth, primarily driven by AI computing operations.

Capital Market Divergence: Repricing Mining Equities

Following earnings releases, mining-related equities exhibited significant divergence in performance:

• Hut 8 shares rose more than 35% during intraday trading on May 6, closing at $108.94, a record high. The move was closely associated with the announcement of the Beacon Point AI data center lease, a long-term contract providing revenue visibility over 15 years.
• Core Scientific shares rose approximately 11% during regular trading but declined about 7.2% in after-hours trading following earnings release.
• American Bitcoin shares posted modest gains during trading before reversing in pre-market activity.

Market behavior suggests that headline losses alone are not the primary valuation driver. Instead, investor attention is increasingly focused on the credibility, scale, and execution of AI infrastructure contracts. Companies with long-term, contracted AI revenue streams appear to receive more favorable valuation treatment, even amid significant accounting losses. Conversely, firms with large impairment charges or weaker visibility into AI monetization face more cautious investor sentiment.

From Bitcoin Mining to AI Infrastructure: Structural Transition in Progress

Core economic logic of the shift

The transition from Bitcoin mining to AI infrastructure is driven by overlapping physical requirements. Both mining facilities and AI data centers depend on large-scale power access, industrial cooling systems, and substantial physical infrastructure.

Rather than repurposing mining hardware, operators are monetizing existing infrastructure assets, including power agreements, land, grid interconnections, and cooling capacity. In many cases, these assets are difficult to replicate due to long permitting timelines for new grid connections in North America, which can take several years.

As a result, existing mining infrastructure has increasingly become a strategic input for AI and high-performance computing (HPC) workloads, where revenue per megawatt can exceed Bitcoin mining returns.

AI contract expansion across the sector

As of 2026, publicly listed mining companies have collectively announced more than $70 billion in AI and HPC-related contracts. Key developments include:

According to CoinShares estimates, AI-related revenue could account for approximately 70% of total revenue for listed mining companies by the end of 2026, up from roughly 30% currently. This suggests a gradual redefinition of the sector from Bitcoin mining operators toward AI-focused data center infrastructure providers.

Conclusion

The Q1 2026 earnings season highlights a clear structural divide in the Bitcoin mining industry. Reported losses are largely driven by Bitcoin price volatility, mandatory fair value accounting under FASB standards, and non-cash impairment charges, rather than purely operational cash flow deterioration.

At the same time, capital markets are increasingly differentiating between companies based on their ability to secure and execute long-term AI infrastructure contracts. Since the 2024 Bitcoin halving, the economic threshold for mining profitability has continued to rise, placing sustained pressure on traditional mining-only business models.

As cumulative AI contract value exceeds $70 billion and mining infrastructure is progressively repurposed for high-performance computing workloads, the industry appears to be undergoing a structural transformation rather than a cyclical downturn.

For market participants, the key analytical focus is shifting toward three variables: the quality of AI contract execution, the sustainability of power and infrastructure advantages, and the evolving relationship between network hash rate dynamics and mining economics.
