Why Are AI Stocks Falling Again?

Microsoft is canceling data center leases, according to a Wall Street analyst.

The artificial intelligence industry is experiencing another TD Cowen shock.

The whole spectrum of companies connected to artificial intelligence — the companies that design the chips, that supply the power, that make the generation equipment — shuddered Wednesday when the brokerage released another note from analysts pointing to evidence that Microsoft was giving up on its data center leases.

“Microsoft has both (1) walked away from +2GW of capacity in both the U.S. and Europe in the last six months that was in process to be leased, and (2) has both deferred and canceled existing data center leases in both the U.S. and Europe in the last month,” the analysts wrote.

Microsoft is one of the biggest players in the artificial intelligence industry, with its near-$14 billion investment in OpenAI and a commitment to spend $80 billion on data center capacity this year.

The company is pulling back, the TD Cowen analysts said, because it had decided not to support incremental increases in training workloads for OpenAI models. Shares in Nvidia, the chip designer that’s become one of the most valuable companies in the world on the back of optimism about artificial intelligence, are down 7% since market close Tuesday, while shares in the power companies Vistra and Constellation are down 9% and 7% respectively. GE Vernova, which makes turbines for gas-fired power plants, is down 9%.

Much of the power industry saw huge increases in their stock prices in 2024, as investors bet on increased demand for electricity from data centers, manufacturing, and electrification. But 2025 so far has been a year of mild expectations.

In February, Cowen analysts issued a similar note warning that Microsoft was pulling back on some of its data center leases. And in January, of course, many of the AI and energy stocks that had been soaring 2024 dropped when the Chinese artificial intelligence company DeepSeek released an open source model comparable in performance to the state of the art in the United States but that required far less computing power to train.

The Cowen analysts were hardly doomy about AI and data center construction, writing that Google and Meta may be “backfilling” the capacity left behind by Microsoft as they seek to expand their own data center footprints.

But the case for across the board optimism may be slightly dimming across the sector. CoreWeave, which buys Nvidia chips and operates data centers, has had to reduce the amount of money its seeking to raise in its planned initial public offering to $1.5 billion, from the over $4 billion it was looking to get from investors earlier in the IPO process, Bloomberg reported. Nvidia, an investor in CoreWeave and its most important supplier, will be “anchoring” the IPO, kicking in $250 million.

Google Bets Big on Virtual Power Plants With 1 Gigawatt Voltus Deal

The additional clean capacity would represent nearly 3% of North America’s existing total.

North America has about 37.5 gigawatts of total virtual power plant capacity, according to energy consultancy Wood Mackenzie’s latest estimate, published last year. That capacity is spread across roughly 2,000 VPPs, which aggregate distributed energy resources like batteries, smart thermostats, and heat pumps to cut, shift, or supply electricity when the grid is under strain — effectively turning them into a single, coordinated power plant.

On Thursday, Google and VPP operator Voltus announced plans to add another 1 gigawatt of clean capacity over the next three or four years — or nearly 3% of North America’s existing total. Under Voltus’ “bring your own capacity” model, Google will fund the VPP to help meet its booming data center power needs, while Voltus will enroll businesses and households across the PJM Interconnection, the notoriously overstrained grid region spanning parts of the Midwest and Mid-Atlantic, compensating them for their participation either directly or through electricity bill credits.

The Federal Reserve raised the federal funds rate by a quarter point, the central bank announced Wednesday afternoon, its first rate change since Chairman Kevin Warsh took his seat in May and its first rate hike in over three years.

The federal funds rate will now sit between 3.75% and 4%. According to projections by regional Federal Reserve presidents and members of the Board of Governors, the central bank expects to hike rates one more time this year.

It’s another hot and expensive summer.

Across the country, average household electricity bills are up 2.7% in the first eight months of the year, according to the latest update to Heatmap and MIT’s Electricity Price Hub, tacking on $4 per month to the typical bill. This level of rise is consistent with the pace set in 2024 and 2025, but faster than 2021 and 2023.
