SoftBank Group Corp's chip maker Arm Ltd has filed with regulators confidentially for a U.S. stock market listing, people familiar with the matter said on Saturday, setting the stage for this year's largest initial public offering.

While SoftBank had said in March it planned to list Arm in the U.S. stock market, the company's IPO registration shows that it is pressing ahead with the blockbuster offering despite adverse market conditions.

U.S. IPOs, excluding listings for special purpose acquisition companies, are down about 22% to a total of just $2.35 billion year-to-date, according to Dealogic, as stock market volatility and economic uncertainty put many IPO hopefuls off.

Arm plans to sell its shares on Nasdaq later this year, seeking to raise between $8 billion and $10 billion, the sources said.

The sources cautioned that the exact timing and size of the IPO are subject to market conditions and asked not to be identified because the matter is confidential.

SoftBank and Arm declined to comment.

There are signs that the IPO market is beginning to thaw. Johnson & Johnson Inc is preparing to list its consumer health business Kenvue Inc in New York next week, hoping to raise about $3.5 billion.

SoftBank has been targeting a listing for Arm since its deal to sell the chip designer to Nvidia Corp for $40 billion collapsed last year because of objections from U.S. and European antitrust regulators.

Since then, Arm's business has fared better than the broader chip industry thanks to its focus on data center servers and personal computers that generate higher royalty payments. The company said sales were up 28% in its most recent quarter.

Arm's IPO is expected to boost the fortunes of SoftBank, which is battling to turn around its giant Vision Fund, which has been hit by losses due to the declining valuations of many of its holdings in technology startups.

Earlier this year, Arm rebuffed a campaign from the British government to list its shares in London and said it would pursue a flotation on a U.S. exchange.

Arm's IPO preparations are being led by Goldman Sachs Group Inc, JPMorgan Chase & Co, Barclays and Mizuho Financial Group.
