IREN Is Switching Off the Business That Made $578 Million
The miner booked a $638.8 million impairment retiring rigs to clear halls for AI tenants. Its $4 billion contracted run rate is still $3 billion above what is actually operating.
SHA-256 · air-cooled
A mid-tier air-cooled machine at 18.5 W/TH. Competent rather than leading: it needs meaningfully cheaper power than an S21 Pro to return the same margin. Its 180-day warranty is half what Bitmain offers on comparable models.

Revenue assumes a 1% pool fee at the current BTC price and network difficulty, with the machine running continuously. Payback needs a hardware cost, which we do not publish because we have no verified retailer feed — add your own purchase price in the calculator.

Data provenance
Manufacturer datasheet as published by retailers; power draw corroborated across three independent sources. Last verified 2026-08-03.
Note: We previously published 3,348 W for this model, which was wrong — the datasheet figure is 3,441 W (18.5 W/TH). MicroBT's own product pages were unreachable, so this was settled against three independent sources that agree. The correction lowers its break-even electricity price slightly.
Any field not listed above is one we could not verify for this machine. We would rather leave a row out than publish a figure you cannot check. Where published sources disagree, we say so instead of picking one. How we verify specifications.

The BLAKE2b chain locked out every SHA-256 rig in existence when it activated on 1 September. The one venue quoting the coin showed a 131.7 per cent bid-ask spread, and no major exchange has listed it at all.

BitGo picked up roughly 250 institutional client relationships and 30 staff. The seller kept a data centre pipeline it says runs past three gigawatts.
