What happened
Iren's five-year Microsoft deal is worth $9.7 billion and covers 200 megawatts at its Childress facility. Micron reported $54.2 billion in fiscal 2026 fourth-quarter revenue, up 479% year over year.
Why it matters
Micron's revenue growth could narrow the market-cap gap to the current leader.
What to watch
Iren's plan hinges on bringing sites online on time; it aims to deliver the first 300 megawatts of its Sweetwater facility by Q4 2027. Micron's CEO guided toward an "even stronger fiscal 2027."
WHO IT HITSInvestors with $1,000 to allocate to AI infrastructure, as well as supply-chain planners at data center operators and memory-chip buyers, are watching whether Iren's Microsoft deal scales and whether Micron's revenue growth holds at current prices.

Both companies sit at different points in the AI build-out. Iren is a converted crypto miner now selling multiyear capacity contracts, while Micron supplies memory chips that every data center uses. Iren's $9.7 billion Microsoft deal gives it a long runway, but construction timelines remain a key variable. Micron's growth has been faster than the market leader's, though the body notes a $1.2 trillion to $5.5 trillion market-cap gap. For readers with $1,000 to allocate, the question is likely whether Iren can convert its multigigawatt pipeline into on-time deliveries and whether Micron's revenue trajectory continues.
