Canaan (NASDAQ: CAN) boosts May bitcoin mining efficiency and projects
Rhea-AI Filing Summary
Canaan Inc. reported its unaudited bitcoin mining update for May 2026, showing continued growth in production efficiency and digital asset holdings. Self-mining generated 90 BTC, with another 24 BTC from customer payments, lifting the company’s treasury to 1,867 BTC and 3,952 ETH at month-end. After a planned hosting agreement expiration, Canaan ended May with 10.05 EH/s of installed and 6.47 EH/s of operating non-joint-venture hashrate. Its North American self-mining fleet reached record efficiency of 17.9 J/TH, about 11% better year over year, while global average efficiency improved to 23.7 J/TH, a 13.5% YoY gain. Joint venture operations produced roughly 45 BTC, nearly matching April despite wildfire-related disruption at the Alborz site, where restoration is underway. Beyond mining, Canaan highlighted an 8 MW hash-to-heat project in the Nordic region and a follow-on order from Tether for high-density hash board modules, underscoring efforts to expand into energy-efficient heating and next-generation compute systems.

Canaan Inc. Provides May 2026 Bitcoin Production and Mining Operation Updates
North American fleet efficiency improved by ~11% YoY, reaching a record 17.9J/TH
Further expanded global operations with hash-to-heat deployment in the Nordic region
SINGAPORE, June 11, 2026 /PRNewswire/ -- Canaan Inc. (NASDAQ: CAN) (“Canaan” or the “Company”), an innovator in crypto mining, today released its unaudited bitcoin mining update for the month ending May 31, 2026.
Management Commentary
“As we continued to streamline our self-mining portfolio and improve operational efficiency, our mining operations delivered solid results during May ,” said Nangeng Zhang, chairman and chief executive officer of Canaan. “Our self-mining operations delivered 90 BTC during the month, with an additional 24 BTC originating from customer payments. As a result, our cryptocurrency treasury reached a record high of 1,867 BTC and 3,952 ETH by the month-end. Following the planned expiration of a hosting agreement during the month, we further refined our mining footprint, ending the month with 10.05 EH/s of installed hashrate and 6.47 EH/s of operating hashrate. Importantly, our North American self-mining fleet achieved an average efficiency of 17.9 J/TH, representing our best regional fleet performance to date and an ~11% YoY growth. Our global average mining efficiency in May was 23.7 J/TH, representing a 13.5% improvement YoY. These results demonstrate the resilience and competitiveness of our operations, even amid ongoing industry margin compression.”
Zhang continued, “ Our joint venture operations generated approximately 45 BTC during May, nearly matching April's production despite wildfire- related disruptions at the Alborz site. Restoration efforts are progressing well, and significant stabilization work has already been completed. We expect the site to return to full operations within the coming week. We would like to thank WindHQ for its rapid and professional response to the disruption, which reflects the strong partnership we have built.”
“Beyond our mining operations, we continue to advance initiatives that demonstrate the broader potential of our infrastructure platform. The expansion of our hash-to-heat deployment in the Nordic region highlights how compute infrastructure can create value beyond traditional mining applications. As demand for AI and computing infrastructure continues to grow, we believe Canaan’s strengths in hardware innovation and energy-efficient systems make us well-positioned to unlock new opportunities where energy and computing can create value together. ”

Recent Corporate Updates:
Won Competitive Bid to Provide Hash-to-Heat Equipment to Nordic District Heating Network
On May 19, 2026, the Company announced that it had been selected to support a district heating network in the Nordic region with a combined capacity of approximately 8 MW. The project utilizes the Company's Avalon A1566HA hydro-cooled units and leverages Canaan's proprietary semiconductor and system design technologies to support dynamic overclocking and underclocking, enabling the stable delivery of hot water at temperatures of approximately 80 degrees Celsius for integration into existing district heating infrastructure. The project builds upon a successful initial deployment of approximately 2 MW, which is currently operating and supplying hot water to local residents. Following the strong performance of the first phase, the Customer placed a follow-on order in March 2026 for an additional 6 MW of capacity. This deployment further demonstrates the commercial viability of the Company's hash-to-heat technology and its potential to accelerate the replacement of legacy heating systems, while creating value beyond traditional bitcoin mining applications through energy-efficient heating solutions.
Extended Collaboration with Tether on New Form Factors for Mining and Compute Systems
On April 28, 2026, the Company announced that it had secured a follow-on order from Tether for high-density mining hash board modules, custom-developed to support next-generation immersion-cooled mining and computing systems. The agreement follows a successful 2025 proof-of-concept (POC) R&D project conducted in partnership with Tether and ACME Swisstech, a Swiss-based R&D firm specializing in innovative mining system solutions. This follow-on order is slated for deployment at a Tether-affiliated mining facility in South America. The collaboration reflects a broader trend toward partner-driven, modular mining architectures, where infrastructure operators design optimized systems around high-performance compute building blocks—combining Canaan’s ASIC expertise with Tether’s drive for optimized, independently cooled operations.
