Shares of IREN (NASDAQ:IREN) are up 27% midday Thursday, joining a broad rally across Bitcoin (CRYPTO:BTC)-miner-turned-AI-infrastructure names. TeraWulf (NASDAQ:WULF) stock is up 18% and Cipher Mining (NASDAQ:CIFR) shares are up 28%, riding a risk-on session with the Nasdaq 100 up 3%.
Even after today’s pop, the year to date (YTD) scoreboard is lopsided. Cipher Mining stock is up 53% YTD and TeraWulf shares are up 56% YTD, while IREN stock is down 2% YTD. The CoinShares Bitcoin Mining ETF (NASDAQ:WGMI), which holds all three names, is up 37% YTD.
That gap has revived a debate that has followed the sector all summer. If the three companies share the same pivot from Bitcoin mining into AI and high-performance computing (HPC) data centers, why has IREN traded so much worse than its peers, and is today’s move the start of a catch-up trade?
A Sector-Wide Rally
Today’s move looks sector-wide rather than IREN-specific. Crypto-linked and AI-infrastructure names are bouncing together, and the broad-market lift of the Nasdaq 100 is doing much of the work. No fresh company release from IREN seems to have triggered the pop, and news feeds have been quiet on all three miners this week.
The one substantive analyst note across the group came from Morgan Stanley (NYSE:MS | MS Price Prediction), which flagged Cipher Mining as a preferred beneficiary of ERCOT’s large-load “Base Load” classification process. That framework could clear advanced Texas data-center projects toward grid connection sooner, a potentially important tailwind for CIFR’s Barber Lake and Black Pearl campuses. Morgan Stanley stock is up 3% today, part of the same risk-on tape lifting the miners.
The Catch-Up Case for IREN
IREN stock’s lag is striking given the company’s contracted book. The company has disclosed a five-year, $3.4 billion AI Cloud contract with NVIDIA (NASDAQ:NVDA) plus up to $2.1 billion of NVIDIA investment vesting as IREN scales toward 600,000 GPUs. IREN’s management is targeting $3.7 billion in annualized recurring revenue and 150,000 deployed GPUs by end of calendar 2026.
The underlying business trend is another mismatch with the tape. IREN’s AI Cloud services revenue nearly doubled sequentially to $33.6 million in Q3 FY2026, while Bitcoin mining revenue fell to $111.2 million as decommissioned equipment drove $140.4 million in non-cash impairments. TeraWulf’s HPC leasing segment jumped 117% quarter over quarter and now contributes over 60% of revenue at $21.02 million.
CEO Daniel Roberts stated on the Q3 FY2026 call, “There are no idle GPUs…all of our operational capacity is fully contracted.” IREN’s secured power portfolio now spans 5 gigawatts across North America, Spain and Australia, the largest of the three names. TeraWulf brings a 2.9-gigawatt platform with over $13 billion in contracted revenue, and CEO Paul Prager has described the “strongest demand environment to date.”
Cipher Mining carries 700 MW of contracted HPC capacity with roughly $787 million in average annualized net operating income. This is anchored by a 15-year, 300 MW, $5.5 billion Amazon (NASDAQ:AMZN) Web Services lease and a 10-year, 300 MW, $3.8 billion Fluidstack and Google agreement.
The valuation split is where the debate sharpens. IREN carries a trailing price-to-earnings (P/E) ratio of 48.18x and is the only one of the three with an actual trailing-twelve-month profit. TeraWulf and Cipher Mining have no TTM P/E ratio since neither is profitable on a trailing 12-month basis, while bears counter that IREN’s Q3 FY2026 revenue of $144.8 million missed consensus estimates as Bitcoin mining hardware was decommissioned, and Reddit (NYSE:RDDT) chatter on IREN turned “very bearish” through late July even as WULF sentiment stayed bullish.
What to Watch Now
The bull-bear split here is unusually clean. WULF and CIFR bring larger cumulative contracted-revenue books at over $13 billion and roughly $11.4 billion, respectively, but heavier generally accepted accounting principles (GAAP) losses and equity dilution. IREN brings the marquee graphics processing unit (GPU) partnership, the largest secured power portfolio, and the biggest 2026 annual recurring revenue (ARR) target of the three, yet the stock has not repriced with its peers.
An additional takeaway is that the sector concentration cuts both ways. The WGMI ETF is a reminder that one macro theme, AI infrastructure demand routed through former Bitcoin miners, is driving all three names on days like this, which means the trio can also sell off together on any wobble in AI capex sentiment.
Investors can watch for whether today’s gains hold into the close and whether the next IREN update on GPU deployment or contract wins shifts the year-to-date picture. Traders should consider keeping their position sizes modest given the volatility that has defined this group in both directions.
