IREN Limited (NASDAQ: IREN) and Nebius Group (NASDAQ: NBIS) both reported earnings recently, but the results looked nothing alike, and the worse-looking quarter may belong to the better long-term buy.
IREN posted June-quarter revenue of $137.2 million, missing the $140.75 million analyst consensus by 2.52%, with a $684 million GAAP net loss driven by a $450.4 million non-cash impairment on decommissioned mining hardware.
Despite the headline loss, IREN’s AI Cloud revenue hit $70.5 million and more than doubled sequentially, signaling that its pivot away from Bitcoin mining is gaining real commercial traction.
CEO Daniel Roberts captured the fundamental challenge facing the company when he said “the digital world can scale almost instantly, but the physical world cannot,” a line that frames IREN’s entire operational risk.
Nebius moved in the opposite direction, with Q2 revenue jumping 454.04% year over year to $582.30 million, beating the analyst consensus by 1.33%, while its AI Cloud unit produced $285.7 million of adjusted EBITDA at a 50% margin.
Four landmark contracts closed during the Nebius quarter, averaging more than a billion dollars each, with remaining performance obligations now standing at an extraordinary $37.49 billion.
IREN owns power, land, substations, cooling and buildings across Texas, British Columbia, Oklahoma, Australia and Spain, with more than five gigawatts of announced capacity, and Roberts wants each layer to earn a margin.
Recent three-year IREN contracts price at more than $20 million per megawatt of IT load, with active discussions reportedly near $25 million, while customer prepayments funded roughly 96% of the Microsoft GPU capital expenditure.
Nebius is more software-forward, with its Aether, Token Factory and Tavily products wrapping its GPU infrastructure, and short-term training deals negotiated at $40 million to $50 million per megawatt, demonstrating clear pricing power.
Concentration risk is real at Nebius, however, with three customers accounting for 24%, 21%, and 14% of Q2 revenue respectively, and the company carrying $8.5 billion in convertible debt with a fair value of $20.8 billion.
IREN’s Horizons 2, 3 and 4 data center expansions target the December quarter, with revenue predominantly expected in the March quarter, and FY2027 capital expenditure guidance sits at $25 billion to $30 billion.
Nebius carries its own heavy funding lift, with $20 billion to $25 billion of 2026 capital expenditure planned and a Vera Rubin rollout scheduled to begin in late 2026 or early 2027.
The market has clearly favored Nebius so far, with NBIS up 149.9% year to date while IREN is down 6.14%, but that performance gap is precisely where the contrarian opportunity lives.
If Roberts delivers on Horizons 2 through 4 on schedule and secures data center financing without heavy equity issuance, the discount between the two stocks could close quickly and decisively.
Nebius suits a growth-at-scale investor looking for a proven compounder, while IREN suits a contrarian who believes Roberts’ “funding flywheel” strategy will deliver and is willing to absorb the execution risk that comes with it.
