Is the Antminer Z15K profitable?

The Bitmain Antminer Z15K mines Zcash on the Equihash algorithm at 525 KH/s, drawing 2,483 W (4.7 J/KH). At $0.08 per kWh it earns about $39.69 a day, spends $4.77 of that on power, and keeps $34.93. That’s around $1,048 a month. It stops making money above roughly $0.666 per kWh.

That puts it #3 of 522 on daily profit across every miner we track, and #3 of 9 Equihash miners on efficiency. At the current best price of $4,647 it would pay for itself in about 4 months if today’s numbers held. They won’t, so treat that as a rough guide. It’s an air-cooled unit, released in August 2026.
