ARM: Arm Stock Doubles Valuation in Five Days as Investors Bet on Cloud and AI Growth

The run-up in Arm’s market cap is a massive windfall for volatile king SoftBank who owns a 90% stake in the UK chip designer.

• Arm stock ARM has been on a tear in the past five days, doubling its valuation to cross $150 billion. The company is still riding the post-earnings optimism from last week when it announced $824 million in revenue and projected an upbeat outlook for the year.
• The UK chip designer, backed by Japan’s giant tech investor SoftBank 9984, kicked off this week’s trading with a 30% pump, closing at $148.97 a share. Just five months ago, Arm dropped on the Nasdaq exchange and had its trading debut, flaunting a price tag of $51 a share.
• Arm has been enjoying a growing market share in the cloud and AI business and investors have been generous with their bids. This said, there are about 1 billion shares outstanding but only 95 million are listed for trading in public markets. The rest, valued at $130 billion, is kept under lock and key by SoftBank, who cannot touch that pile until March 12.
