Microsoft, one of the largest buyers of rented AI computing capacity, is taking a harder look at its agreements with the specialized cloud providers known as neoclouds. The review comes as shares of companies in the group are already deep in bear market territory.
CoreWeave closed the week at $46.40, about 66 percent below its high for the year, while IREN has fallen roughly 70 percent from its peak, according to a report published by KuCoin. The report suggests the decline could continue if Microsoft pulls back on future commitments.
Microsoft Tightens Oversight of Neocloud Partners
Citing Bloomberg, the report says Microsoft is reassessing its relationships with neocloud providers because of project delays and rising costs. The company is reportedly applying closer oversight to projects run by firms including Nebius, IREN and Nscale.
The most significant detail is that senior Microsoft executives are said to be weighing a pause on signing new deals. For a sector that depends heavily on a small number of very large customers, that would be a meaningful shift.
Why Microsoft Matters So Much to the Sector
Microsoft is a major client for both CoreWeave and IREN, and it has signed agreements worth more than $80 billion with neocloud providers over the past few years. Any slowdown in its spending would ripple through the revenue outlook for these companies.
There are already signs of a cooling appetite. Microsoft has begun turning off capacity it leased from Oracle, pointing to the Nvidia GPUs in that arrangement as outdated. That move raises questions about whether large tech companies will renew leases once current contracts expire.
Other Big Customers Are Also Recalibrating
Microsoft is not the only large customer adjusting course. Meta Platforms, another key buyer of neocloud capacity, is reportedly exploring whether to lease its surplus space to other AI companies.
OpenAI, also a significant customer, is said to be looking for ways to reduce costs. That effort could lead it to revisit the terms of its contracts with neocloud providers, adding further uncertainty to the sector's demand picture.
A Crowded and Increasingly Competitive Market
While demand signals soften, supply is growing. Several Bitcoin mining companies, including Riot Platforms, MARA Holdings and Core Scientific, are repositioning their infrastructure toward AI computing.
Independent players such as Lambda, Firmus and Nscale are also competing for business. SpaceX has entered the field as well and recently raised $40 billion to expand its operations, according to the report.
Analysts Warn of Future Write-Downs
Research firm Gartner has added to the cautious tone. In a recent report, it identified $3.5 trillion in potential impairments tied to AI infrastructure and said neoclouds would be the most exposed when those write-downs hit in late 2030.
Impairments occur when assets such as data centers or chips lose value faster than expected, which can weigh heavily on balance sheets for capital-intensive businesses.
What the Shift Means for AI Infrastructure Players
CoreWeave is set to report earnings next week, and analysts expect third-quarter revenue to rise 159 percent to $3.54 billion, based on Benzinga data. Strong growth figures, however, may not settle investor concerns about future demand.
For founders and investors in AI infrastructure, the episode highlights the risk of depending on a handful of hyperscale customers. As buyers like Microsoft scrutinize costs and timelines more closely, providers that can deliver reliably and diversify their client base may be better placed to weather a slowdown.
