Nebius, CoreWeave, IREN Stocks Rise After Alphabet Raises AI Capex Forecast

Citi says growing political opposition to artificial intelligence infrastructure ahead of the November U.S. midterm elections has not materially weakened the data center construction pipeline. Data center development has become a bipartisan flashpoint, with local governments introducing moratoriums and at least 15 state legislatures proposing tighter regulatory restrictions, yet spending remains strong as AI infrastructure demand continues to support development. The impact has been concentrated among speculative and early-stage projects, which are increasingly delayed or cancelled during local approval processes, while late-stage developments that have already secured sites and grid connections continue to move ahead. Hyperscalers are seeking workarounds to power constraints and local restrictions, with Amazon pursuing direct investment in nuclear development with Dominion Energy and Meta securing a major nuclear power purchase agreement with Constellation Energy. Citi does not expect another market shock comparable to the emergence of DeepSeek, arguing investors have already adjusted to the prospect of highly efficient Chinese models, though it flags a potentially greater risk from governments restricting models deemed too dangerous, which could abruptly create excess computing capacity.

IREN's fair value estimate has been trimmed from US$80.93 to US$79.03, a modest adjustment reflecting a mix of growing AI cloud contracts and ongoing questions around execution and supply build out through 2027. The revision lifts revenue growth assumptions to 168.01% from 125.79% and net profit margin expectations to 11.73% from 5.79%, while the future P/E assumption drops to 31.26x from 90.29x and the discount rate rises to 9.41% from 8.83%. On the bullish side, JPMorgan shifted IREN from Underweight to Overweight with a US$65 price target, citing a partnership with Nvidia, new customer signings and higher industry pricing, while H.C. Wainwright raised its target to US$90 after IREN announced US$2.8b of new multi year AI cloud contracts and lifted its 2026 AI cloud annual recurring revenue target to more than US$4b. Northland initiated IREN at Outperform with a US$99 price target, and Freedom Capital upgraded the stock from Hold to Buy. Freedom Capital nonetheless flagged execution on supply additions over the next two years as a central risk, noting the story depends heavily on adding capacity on schedule.

Nscale, the London-based AI data center developer backed by Nvidia and Microsoft, filed publicly for an initial public offering in New York, seeking to raise as much as $3 billion. The company reported a net loss of $1.02 billion on revenue of $140.6 million for the six months ended June 30, compared with a net loss of $368.9 million on revenue of $10.4 million a year earlier, according to its Friday filing with the US Securities and Exchange Commission. Spun off from a cryptocurrency mining operation in early 2024, Nscale was valued at about $14.6 billion in a March Series C round led by Aker ASA and 8090 Industries, with Nvidia and Nokia Oyj also participating. The company has agreed to add more than 30,000 Nvidia chips to an existing rental agreement with Microsoft at its Narvik, Norway gigafactory, and Anthropic has agreed to spend $45 billion to rent AI cloud computing power from its flagship West Virginia data center development. The offering is being led by Goldman Sachs, JPMorgan Chase and Morgan Stanley, with shares expected to trade on the New York Stock Exchange under the symbol NSCL.
