Is the Antminer S23 profitable?

The Bitmain Antminer S23 (318T) mines Bitcoin on the SHA-256 algorithm at 318 TH/s, drawing 3,498 W (11.0 J/TH). At $0.08 per kWh it earns about $11.94 a day, spends $6.72 of that on power, and keeps $5.23. That’s around $157 a month. It stops making money above roughly $0.142 per kWh.

That puts it #43 of 522 on daily profit across every miner we track, and #10 of 262 SHA-256 miners on efficiency. It isn’t in stock with us at the moment. It’s an air-cooled unit, released in January 2026.
