NEW YORK, Jan 20, 2026, 17:50 ET — After-hours trading session.
- CoreWeave shares slipped almost 6% by the close and dipped further in after-hours trading.
- A shareholder lawsuit linked to data center delays and revenue timing resurfaced.
- Traders are focusing on tariff news, bond yields, and the upcoming CoreWeave update as Wednesday unfolds.
CoreWeave Inc shares dropped 5.9% to $95.22 by Tuesday’s close and slid further to $94.54 in after-hours trading following the 4 p.m. session. Over the past year, the stock has swung between $33.52 and $187, highlighting the volatile mood around the AI infrastructure sector. 1
This matters because CoreWeave acts as a high-beta indicator for how quickly major clients are still ready to pay for computing power—and how low suppliers can push costs. When investors pull back from risk, these stocks tend to take the initial hit.
Tuesday brought a fresh jolt: a new securities class action highlighting delays in launching additional data center capacity. Traders pay closer attention to that angle than the legal timetable.
The broader market took a hit. Wall Street registered its steepest single-day fall in roughly three months after President Donald Trump revived tariff threats against parts of Europe, announcing a 10% import tariff starting Feb. 1, climbing to 25% on June 1. Jamie Cox, managing partner at Harris Financial Group, said he’d be “surprised if there was a 3% to 5% drop this week.” 2
CoreWeave, set up in 2017, went public on Nasdaq in March 2025 and offers cloud computing tailored for AI tasks. Its stock has fluctuated sharply in response to updates on customer demand, expansion speed, and funding climate. 3
In its latest quarterly update from November, the company announced revenue around $1.36 billion and revealed a revenue backlog of $55.6 billion as of September 30. That report also highlighted interest expenses near $311 million for the quarter—a figure closely watched by investors amid fluctuating bond yields. 4
Nasdaq reported Tuesday that a securities class action has been filed, targeting investors from March 28, 2025, through Dec. 15, 2025. The deadline to appoint a “lead plaintiff” — the representative investor who will guide the lawsuit — is set for March 13, 2026. Reed Kathrein, partner at Hagens Berman, said the firm is probing whether CoreWeave deliberately misled shareholders. This follows a Wall Street Journal report on delays involving a third-party data center developer at a Denton, Texas site planned for OpenAI. 5
The risk to the stock goes beyond just legal expenses. Any new indication of capacity delays, slower customer growth, or tighter capital markets could push investors to rethink a business model that relies on rapid expansion funded upfront.
Coming next is the company’s earnings report on Feb. 18. Traders will be watching closely for updates on capacity deliveries, demand from major customers, and spending trends heading into 2026. 6
