IREN’s bitcoin mining revenue drops 58% as firm plans full exit by year-end

IREN began as Iris Energy, an Australian-founded bitcoin miner that listed on Nasdaq and built data centers powered by renewable energy in Texas and Canada. Like Core Scientific and Cipher before it, the company has spent the past two years redirecting that same power and real estate toward AI cloud and GPU hosting, as post-halving block rewards and rising network difficulty squeezed mining margins across the industry.

Shareholders who bought IREN for bitcoin exposure now hold a company actively unwinding that business, with mining revenue down 58% and a stated plan to exit entirely by December. Investors seeking pure mining exposure must look to rivals such as Marathon or Riot, while AI customers, including those tied to Microsoft, gain claim on IREN's power capacity and data-center build-out, now central to its $200 million AI cloud revenue line.

The reshuffle raises a fair question about what kind of company IREN now is: a miner diversifying opportunistically, or one abandoning a business whose economics no longer work, repackaged as an AI infrastructure story. Stranded power and purpose-built data centers are the common thread, but betting that GPU hosting scales faster than mining revenue shrinks is a wager, not a settled outcome, and the 17% share drop suggests the market isn't fully convinced yet.

December is the checkpoint for whether IREN substantially completes its mining exit as promised, and early 2027 is now the marker for its $4 billion AI run-rate target, a timeline that has already slipped once alongside Microsoft-related delivery shifts. The next quarterly report will show whether AI cloud revenue keeps compounding at anything near its 182% pace or whether the transition drags further past these dates.
