(Reuters) - Nvidia ( NVDA )-backed CoreWeave is aiming to raise as much as $2.7 billion in its U.S. initial public offering, a regulatory filing by the AI startup showed on Thursday.

The artificial intelligence-focused cloud services provider and some of its investors are looking to sell 49 million shares priced between $47 and $55 each.

The offering is expected to be a key test of appetite for AI-focused companies after the launch of Chinese startup DeepSeek's low-cost model and an analyst report Microsoft had cut back on data-center leases tempered the once red-hot demand.

Meanwhile, stock market volatility - driven by uncertainty over President Donald Trump's tariffs and renewed recession fears - also threatens to stall the U.S. IPO market's recovery, analysts say.

Earlier this month, CoreWeave signed a five-year contract worth $11.9 billion with OpenAI.

The deal will give OpenAI a stake in the company, which will issue shares worth $350 million to the ChatGPT maker through a private placement at the time of its IPO.

The company, which provides access to data centers and high-powered chips for AI workloads, mainly supplied by Nvidia ( NVDA ), is aiming to trade on the Nasdaq under the ticker symbol "CRWV."

Morgan Stanley, J.P. Morgan and Goldman Sachs are leading a syndicate of Wall Street banks underwriting the offering.
