What Canaan Reported for May 2026

Canaan Inc. released an unaudited Bitcoin mining update on June 11, 2026, covering the month ending May 31, 2026. The Nasdaq distribution of Canaan’s May update identifies the company as Canaan Inc. and reports results for self-operated mining, joint-venture operations, mining infrastructure, and its digital-asset treasury. The original Canaan release on PR Newswire labels the figures unaudited.

The headline figure was 90 BTC from self-mining during May. Canaan separately reported 24 BTC originating from customer payments. That distinction matters because the two amounts do not describe the same economic activity. Self-mining reflects Bitcoin produced by the company’s own operating portfolio. Customer-payment Bitcoin relates to the company’s equipment or hosting business and should not be counted as additional mined production.

The release also reported a record month-end cryptocurrency treasury of 1,867 BTC and 3,952 ETH. Canaan’s note defines the balance-sheet figure as assets owned by the company, including Bitcoin and ETH receivables, while excluding Bitcoin and ETH received as customer deposits. The number is therefore a balance-sheet measure rather than a claim about how much the company mined in May.

How the 90 BTC Figure Is Defined

The 90 BTC figure is a monthly operating result from Canaan’s self-mining portfolio. The company described the update as unaudited and used rounded numbers in the operating tables. It should therefore be cited as a company-reported May production figure rather than as an audited production number.

Self-mining output depends on the machines that are energized, the power available to them, the operating hashrate, pool and facility arrangements, Bitcoin network conditions, and the company’s allocation between operating and installed capacity. The release does not say that every installed machine ran continuously during the month.

The company also reported a planned hosting-agreement expiration that reduced part of its footprint. That operating change helps explain why installed capacity, operating capacity, and production must be reported separately. A higher installed hashrate does not automatically produce a higher monthly Bitcoin total.

The site’s Digital Asset funding analysis covers a different type of digital-asset company event. A funding announcement concerns capital formation. Canaan’s update concerns operating output and balance-sheet holdings. The two should not be compared as if they were the same financial metric.

Treasury Holdings Reached a Reported Record

Canaan said its cryptocurrency treasury reached a record high of 1,867 BTC and 3,952 ETH at the end of May. The word record is used here because it appears in the company’s release. It does not mean the company was the largest corporate holder, nor does it establish a ranking against other public miners.

The treasury number includes the company’s stated balance-sheet holdings and receivables while excluding customer deposits. This definition prevents a common reporting error. A platform may hold digital assets on behalf of customers without owning them economically. Canaan’s note says those customer deposits are excluded from the reported treasury measure.

A treasury balance can change for several reasons. Mining can add assets. Customer-payment arrangements can add assets. Sales, transfers, accounting classifications, receivables, and price movements can change the balance-sheet presentation. The May release gives the month-end holdings, but it does not by itself provide a full reconciliation of every movement during the month.

The update therefore supports a narrow conclusion. Canaan reported more Bitcoin and ETH on its balance sheet at May month-end than in its prior reported position. It does not support a claim about the company’s future Bitcoin strategy, the market value of the holdings, or the likely return to shareholders.

Hashrate and Efficiency Snapshot

Canaan reported 10.05 EH/s of non-joint-venture installed hashrate and 6.47 EH/s of non-joint-venture operating hashrate at month-end. The installed figure reflects capacity that was installed. The operating figure reflects capacity in operation under the company’s definitions. The gap between them shows why installed capacity should not be used as a direct substitute for production.

The company reported joint-venture installed hashrate of 4.82 EH/s and joint-venture operating hashrate of 2.83 EH/s. Canaan’s note says the joint-venture metrics are shown separately and are not included in Bitcoin production or average all-in power-cost calculations in the same way as the non-joint-venture portfolio.

Efficiency was reported as 17.9 J/TH for the North American non-joint-venture fleet and 23.7 J/TH for the global non-joint-venture average. Canaan also said global average mining efficiency improved 13.5% year over year. These are company-reported operating measures. They indicate energy used per unit of computing work, not profit per Bitcoin.

Why 24 BTC from Customer Payments Is Separate

Canaan reported an additional 24 BTC from customer payments. The release does not describe that amount as self-mined Bitcoin. It is associated with the company’s equipment and hosting activities, so it should be shown separately from the 90 BTC mining result.

This distinction is relevant for readers comparing mining companies. One company may receive Bitcoin from customers, operate machines for customers, own machines directly, or combine all of those activities. A headline that adds every Bitcoin movement together can overstate direct production.

The company’s balance-sheet note also excludes customer deposits from the treasury definition. That is another reason to keep the customer-payment figure separate. The origin of an asset and the company’s ownership of it are different questions.

The correct reading is not that Canaan mined 114 BTC through self-operated mining. The primary release supports 90 BTC of self-mining and a separate 24 BTC from customer payments. Any total that combines them would need a clear label and should not be called production.

Joint-Venture Operations and the Alborz Disruption

Canaan said its joint-venture operations generated approximately 45 BTC during May. The release described that amount separately from the 90 BTC self-mining result. It also said the joint-venture portfolio faced wildfire-related disruption at the Alborz site and expected the site to return to full operations in mid-June.

The company’s note says its joint ventures represent a 49% stake in the Alborz, Bear, and Chief Mountain facilities in West Texas. The joint-venture hashrate figures are therefore reported separately from the non-joint-venture portfolio. The release also says joint-venture metrics are not included in Bitcoin production or average all-in power-cost calculations in the same way as the non-joint-venture figures.

These distinctions affect comparability. A reader who adds 90 BTC and approximately 45 BTC might create a combined operational figure, but it would combine categories that Canaan presents separately. The more defensible approach is to report each category with its scope and keep the joint-venture amount labeled as approximately reported by management.

What the Release Says About Project Footprint

As of May 31, Canaan reported 12 active mining projects globally. The release listed 9.29 EH/s of global operating computing power, 14.86 EH/s of installed computing power, 0.10 EH/s of expected computing power, and 14.96 EH/s of estimated total computing power.

The company’s project table covered America, the joint-venture WindHQ portfolio, Canada, Ethiopia, the Middle East, and Malaysia. The release defines operating, installed, expected, and estimated total computing power separately. Those definitions should be retained because the terms describe different stages of deployment.

Installed capacity is not the same as energized capacity. Expected capacity is not the same as installed capacity. Estimated total capacity combines the company’s defined installed and expected categories. These are infrastructure measures and do not directly state revenue, gross margin, or cash generation.

The site’s DeFi funding report and stablecoin settlement report cover other parts of the digital-asset infrastructure market. Canaan’s project count should be interpreted as an operating footprint, not as a market-share ranking.

Power Cost and Mining Economics

Canaan reported an average all-in power cost of US$0.043 per kWh during May. The release defines this as a weighted average cost of power if all machines consisting of installed computing power were energized. It is therefore a company-defined operating metric, not a complete measure of total cost.

Mining economics also depend on equipment depreciation, hosting expenses, labor, maintenance, pool fees, financing, Bitcoin prices, network difficulty, curtailment, and the share of installed machines that operate. The primary release does not provide enough information to calculate Canaan’s May profit from the power-cost figure alone.

Energy efficiency and power cost are related but not interchangeable. J/TH measures energy efficiency of computing work. US$0.043 per kWh measures power cost under the company’s stated definition. Neither number alone tells readers how much cash the company generated or what return an investor received.

The company also described a Nordic hash-to-heat project and other infrastructure initiatives. Those announcements may broaden the business model, but they do not change the definition of the May self-mining result. Any future contribution from those projects would require separate operating and financial disclosure.

Canaan’s Business Model Beyond Self-Mining

Canaan describes itself as a technology company focused on ASIC high-performance computing chip design, chip research and development, computing equipment production, and software services. The Avalon brand is part of that mining-equipment business. Self-operated mining is one component of a broader model that also includes equipment and infrastructure activity.

This matters when interpreting the 24 BTC from customer payments. A mining-equipment company can receive customer consideration in digital assets while also running its own mining fleet. The payment is evidence of a customer transaction under the company’s report. It is not evidence that the company mined the asset.

Canaan reported a follow-on order from Tether for high-density mining hash board modules and described a Nordic district-heating deployment. Those disclosures show the company is presenting its hardware and energy infrastructure as part of its strategy. They are not a guarantee of future revenue or margin expansion.

The company’s release includes forward-looking language and a safe-harbor notice. Readers should separate historical May results from management expectations about future deployment, demand, AI infrastructure, energy systems, or mining expansion.

What the Update Does Not Prove

The May update does not prove that Canaan was profitable in the month. It does not provide a full income statement, cash-flow statement, or audited treasury reconciliation. It does not establish that the 1,867 BTC and 3,952 ETH holdings will rise in the next month.

The update does not prove that the company is one of the largest public Bitcoin holders. That would require a dated comparison set and a consistent definition of corporate holdings. It also does not prove that the company’s stock will rise because the treasury reached a reported record.

The release does not give a price basis for a market-value calculation in the cited operating update. It is therefore safer to state the asset quantities and omit a dollar valuation. A market price can move while the coin count stays unchanged, and the coin count can change while the market price falls.

The site’s valuation coverage provides context for why a headline number should not be mistaken for a complete valuation. The Canaan update is an operating disclosure, not a valuation report.

How to Read the Data with Bitcoin Market Context

Bitcoin market conditions can affect the interpretation of a miner’s monthly report. A higher Bitcoin price may raise the value of production, while network difficulty, power prices, hosting terms, and machine availability can affect output and cost. The May release itself does not provide a complete sensitivity analysis for those variables.

The correct workflow is to start with the reported production and treasury figures, then ask what each number measures. The 90 BTC figure is self-mining output. The 24 BTC figure is customer-payment Bitcoin. The 1,867 BTC figure is a month-end balance-sheet holding under Canaan’s definition. The 10.05 EH/s and 6.47 EH/s figures describe installed and operating non-joint-venture hashrate.

The site’s Japan crypto bill analysis shows a similar distinction between an event and its legal effect. In Canaan’s case, an operational disclosure should be read as a dated report of company metrics, not as a guarantee of future performance.

Readers should also note that Canaan’s release is unaudited. The disclosure is useful for timeliness, but a full assessment of liquidity, debt, revenue, costs, and accounting treatment would require the company’s financial statements and filings for the relevant period.

Conclusion: Canaan 90 BTC May 2026

Canaan reported 90 BTC from self-operated mining in May 2026 and a separate 24 BTC from customer payments. At May month-end, the company reported 1,867 BTC and 3,952 ETH on its balance sheet under its stated treasury definition.

The release also reported 10.05 EH/s of installed non-joint-venture hashrate, 6.47 EH/s of operating non-joint-venture hashrate, 17.9 J/TH North American non-joint-venture efficiency, 23.7 J/TH global non-joint-venture efficiency, and US$0.043 per kWh of average all-in power cost under the company’s definition.

The central editorial point is separation. Self-mining output, customer-payment Bitcoin, joint-venture production, and treasury holdings are different categories. Combining them without labels can make the headline look stronger than the underlying disclosure. The May update is informative, but it is unaudited and does not by itself establish profitability, valuation, or investment return.

Canaan’s May 2026 update supports a precise description of production, holdings, and operating capacity. It does not remove the need to review audited financial statements, subsequent updates, and market conditions before making any investment decision.
