TeraWulf Falls 5% as AI Infrastructure Names Extend a Month-Long Slide; IREN Drops 4%, Applied Digital Declines 3%

TeraWulf (NASDAQ:WULF) stock is declining 5% to $14.71 in Tuesday morning trading, extending a slide that has taken the shares down 15% over the past month. Even after the drawdown, TeraWulf stock is up 28% year to date (YTD), so today reads as the AI hosting group giving back a summer rally rather than a new leg lower.

Also sliding, IREN (NASDAQ:IREN) stock is down 4% to $41.25. At the same time, Applied Digital (NASDAQ:APLD) stock is slipping 3% to $23.84, while carrying a heavier 24% loss over the past month.

The Global X Data Center & Digital Infrastructure ETF (NASDAQ:DTCR) is down 0.2% to $27.17. For broader market context, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is down 0.6% to $756.55. So, while there’s fear in the markets, WULF is certainly lagging many other stocks today.

Data-Center Repricing in Effect

No fresh company release from TeraWulf accounts for a decline of this size today. The move fits a continuing repricing across data center and AI hosting names, and the past-month figures for TeraWulf and Applied Digital both carry that read. With the DTCR fund and the broad tape close to flat, today’s pain is concentrated in the hosting names rather than the market around them, and momentum from a summer AI infrastructure rally has clearly cooled.

Peer names Cipher Mining (NASDAQ:CIFR) and Core Scientific (NASDAQ:CORZ) sit inside the same structure: heavy capex to convert Bitcoin (CRYPTO:BTC) mining sites into AI and HPC hosting, GAAP losses distorted by non-cash warrant charges, and contracted revenue that arrives mostly in 2027 and 2028 (we profiled seven suppliers powering the broader AI data-center buildout in a free report here). Core Scientific’s landmark 15-year hyperscaler partnership covers 530 MW across 5 sites, with initial delivery in early 2027. Cipher Mining tapped an $810 million bond offering at 6% to fully fund its Stingray project, and its contracted portfolio targets $793 million in average annualized NOI once stabilized.

Group Isn’t Moving as One Block

Applied Digital has fallen much harder over the past month while dropping less than TeraWulf today, so this cohort isn’t trading as a single block. TeraWulf’s Q2 2026 revenue of $44.77 million missed the $50.49 million estimate, but HPC lease revenue climbed to $31.93 million and now represents more than 70% of the mix. That mix shift is what YTD buyers of TeraWulf stock have been paying for.

On the IREN side, AI Cloud revenue more than doubled sequentially to $70.5 million in fiscal Q4 2026, and IREN is targeting $4 billion in contracted ARR operational by December 31. Applied Digital, in turn, signed a 15-year lease with a U.S. investment-grade hyperscaler for 200 MW at Polaris Forge 2 and closed a $2.15 billion private offering of 6.75% Senior Secured Notes due 2031. The order books are stacking, but delivery clocks keep landing in 2027 and 2028.

The bull case for TeraWulf rests on the AI hosting contracts that drove the YTD gain still being in place, including the 20-year Anthropic lease at Kentucky’s Justified Data Campus for 401 MW, worth up to $19 billion of contracted revenue over the initial term. The bear case for TeraWulf is that a business valued on future contracted capacity reprices fast whenever the market questions the pace of the AI buildout, and initial Anthropic delivery isn’t scheduled until the second half of 2027. Cash at TeraWulf stood at $2.62 billion at last report, which limits any near-term funding overhang.

TeraWulf’s strategy also runs beyond the Anthropic lease. Management is monetizing its $530 million sale of a 50.1% Abernathy JV interest, acquired the Muskie Data Campus with initial service targeted for Q4 2028, and picked up FERC authorization for the Chesapeake Morgantown site that could support up to one gigawatt of data center capacity. At stabilization, TeraWulf targets $1.5 billion in average annual NOI and more than $27 billion in total contracted revenue across the platform.

What to Watch Next

TeraWulf’s next hard milestone at Lake Mariner is CB4, which management said “is in commissioning and remains on track for initial delivery in late September.” CB5 is advancing toward initial energization in very early January, according to the Q2 2026 call, and completion of prior building CB3 has already activated a $600 million hyperscaler credit-support tranche tied to the Fluidstack lease.

The DTCR ETF read points to a cluster-level repricing rather than a verdict on TeraWulf itself. Investors can watch for whether the spread between the fund and the hosting names widens further into the close, and Cipher Mining’s Barber Lake rent commencement expected in October is the next dated peer catalyst. Given the beta these names carry, sizing your exposure to the group in line with the volatility they have shown all year is the sensible frame.
