Chip Maker ARM Shares Up 98% This Week

Arm Holdings, the UK-based chip designer, has experienced a remarkable surge in its stock market value, nearly doubling in less than a week, fueled by investor optimism surrounding the artificial intelligence (AI) sector.

Following the release of its financial results last Wednesday, which highlighted the increased demand for AI-related technology, Arm's shares have risen by over 98%.

Arm, headquartered in Cambridge, has a significant presence in the global smartphone market, with its chips powering nearly every smartphone.

The company was privatized by Japan's SoftBank in 2016 but returned to the stock market in September of the previous year.

The recent spike in Arm's shares is in line with the broader trend in the chip industry, exemplified by Nvidia, whose shares have more than tripled in the past year due to the surging demand for AI chips.

Nvidia's success in the AI market has propelled it to become one of the most valuable publicly-traded companies globally, boasting a market valuation of approximately $1.8 trillion (£1.4 trillion).

This achievement places Nvidia among the elite "Trillion-dollar club," alongside tech giants Apple, Microsoft, Alphabet, and Amazon.

While Arm's technology is not directly utilized for AI tasks, chip manufacturers like Nvidia opt for Arm's central processing units (CPUs) to complement their AI-specific chips.

Beyond Nvidia, Arm serves other notable clients such as Taiwan Semiconductor Manufacturing Company (TSMC) and well-known consumer brands like Apple.

The increasing demand for Arm-designed chips extends to the automotive industry, particularly as self-driving technology continues to advance.

Established in 1990 by a group of chip designers in Cambridge, Arm was acquired by SoftBank in 2016 for $32 billion. SoftBank had initially planned to sell Arm to Nvidia in 2020, but in April 2022, the deal was shelved due to regulatory objections worldwide. Instead, SoftBank opted to sell shares of Arm on the Nasdaq stock exchange in New York.

This surge in Arm's shares brings positive news for SoftBank, which has faced losses due to declining valuations in some of its investments, including troubled office space firm WeWork.

Despite SoftBank retaining a roughly 90% stake in Arm, the recent boost in Arm's shares has contributed to a nearly 30% increase in SoftBank's own shares over the past week.
