Short Interest Monitor: CRWV, SMCI, NBIS

The latest edition of the Short Interest Monitor is heavy on technology names. Half the companies on the list operate in some part of the AI space. Others include Domino's Pizza (DPZ), home furnishing retailer Wayfair (W), and cruise ship operator Norwegian Cruise Line Holdings (NCLH).

AI infrastructure company CoreWeave (CRWV) saw one of the biggest jumps in short interest in early June. CRWV is a "picks-and-shovels" AI play, and it depends on access to high-performance compute, leaving it vulnerable to shifting investor sentiment. Overall cooling sentiment toward the AI space, at least for the moment, might be one factor, but some investors might also be concerned about CoreWeave's ability to convert a massive order backlog into profits, especially as it faces rising costs. The company reported a worse-than-expected first-quarter loss, while capital spending is predicted to more than double this year (to more than $30 billion) as it tries to meet surging demand. Its share price tumbled last week, despite the company being added to the Nasdaq-100®.

Super Micro Computer (SMCI) is another AI-linked company coming under growing short-interest pressure. Needing to raise money to meet demand, SMCI's shares plunged on June 10 after the company announced plans to raise $7 billion via equity and equity-linked financing deals, part of an effort to fund purchases of components needed to fill $39 billion in recent AI server orders. Shares fell sharply at the time due to concerns about dilution and margins, but they surged last week after SMCI announced a new data center blueprint using long-time partner Nvidia's (NVDA) chips. Shares jumped more than 20% over two days, perhaps partly fueled by short-covering.

The rise in short interest in AI infrastructure firm Nebius Group (NBIS) comes after the company's shares more than doubled in April and May. The cloud computing specialist was little known early in the AI boom until Microsoft (MSFT) became a major client late in 2025. Nebius also gained attention as it expanded through acquisitions and partnerships, including a $643 million purchase of Eigen AI announced last month and a deal with Meta (META), announced in March, to supply AI infrastructure. After the recent runup, some investors may be wary of the rich valuation or wonder about the prospects for further near-term gains. Nebius also faces high demand for capital, and some investors see customer concentration risk.
