Canaan Inc., the Nasdaq-listed Bitcoin mining hardware maker, closed May 2026 with 1,867 BTC in its corporate treasury. That’s up 41 BTC from the 1,826 BTC it held at the end of April, continuing a steady accumulation streak that’s become one of the quieter corporate Bitcoin plays on public markets.
The company also holds 3,952 ETH alongside its Bitcoin stash. But Bitcoin is clearly the main event here.
How Canaan keeps adding to the stack
The 41 BTC monthly increase didn’t come from a single source. Canaan self-mined 90 BTC during May 2026, a figure powered by its installed hashrate of 10.05 EH/s running at an average efficiency of 23.7 J/TH. On top of that, the company received 24 BTC from customer payments.
Quick math: that’s 114 BTC coming in during the month, but only 41 BTC net added to the treasury. The gap suggests Canaan sold or deployed roughly 73 BTC to cover operational costs, capital expenditures, or other business needs.
