Top 20 US stock trading volumes on March 26: Rumors that Intel and AMD plan to raise CPU product prices

Wednesday’s top US stock by trading volume, Nvidia, closed up 1.99%, with a trading volume of $28.99B. Reports indicate that Schlumberger (SLB) has expanded its collaboration with Nvidia to jointly develop AI infrastructure and models aimed at large-scale deployment in the energy industry.

Both companies stated that this partnership will focus on modular data center design, the development of “Energy AI Factories,” and enhancing accelerated computing capabilities on the SLB digital platform.

Under the agreement, Schlumberger will serve as a modular design partner for Nvidia’s DSX AI Factory, utilizing off-site manufacturing to improve reliability, reduce costs, and enable faster deployment and scaling of data center capacity.

Second place, Tesla, rose 0.76%, with a trading volume of $21.38B. Sources reveal that Elon Musk’s rocket and satellite manufacturing company SpaceX is considering setting its IPO fundraising target at an all-time high, surpassing any previous global company’s fundraising scale.

One insider said SpaceX is weighing a fundraising amount around $75 billion. Some sources have discussed the possibility of raising over $70 billion with potential investors.

These figures are far above the previously reported $50 billion target, more than doubling the current global IPO record—Saudi Aramco’s $29 billion listing in 2019.

Some insiders indicate SpaceX still seeks to go public in June, though the timeline may shift. Bloomberg reported in February that the company might submit IPO documents as early as this month in secret.

Third place, Micron, fell 3.4%, with a trading volume of $20.75B. Micron Technology has launched a cash tender offer to repurchase up to $5.4 billion of its outstanding senior notes. This is part of the company’s debt management plan.

The offer involves various debt instruments, including the 5.300% notes due 2031, the 5.650% notes due 2032, two series of 5.875% notes due 2033, the 5.800% notes due 2035, and the 6.050% notes due 2035. This move allows Micron to adjust its capital structure by repaying or restructuring high-cost debt.

Fourth place, SanDisk, declined 3.5%, with a trading volume of $13.69B. According to market news on March 25, 2026, SanDisk announced a $1 billion investment to acquire approximately 139 million shares of Nanya Technology, which is expected to give SanDisk about 3.9% ownership in Nanya.

SanDisk’s investment aims to strengthen its position in the DRAM (Dynamic Random-Access Memory) sector and to establish a multi-year supply agreement with Nanya Technology.

As part of the deal, Nanya will supply DRAM products to SanDisk under a multi-year strategic supply agreement, marking a shift from a simple buyer-seller relationship to a deeper strategic partnership. After the acquisition, SanDisk will hold about 3.9% of Nanya’s outstanding common shares, becoming a significant shareholder. The purchase price was a 15% discount to Nanya’s 30-day average price.

Sixth place, AMD, rose 7.26%, with a trading volume of $10.45B. Reports suggest the chipmaker plans to raise CPU prices by 10%-15%, indicating strong demand and pricing power in the semiconductor market, with AMD and Intel shares climbing over 7%.

According to media reports, both Intel and AMD have informed customers of planned price increases for their CPU lines starting in March and April. Multiple sources indicate an average increase of 10% to 15%, with some products seeing larger hikes.

Eighth place, Amazon, up 2.16%, with a trading volume of $7.64B. Citibank raised its target price for Amazon, citing expectations that the growth of Amazon Web Services (AWS) will accelerate amid rising demand for AI infrastructure.

Citibank maintained a “Buy” rating and increased the target price from $265 to $285. Previously, based on agreements with OpenAI, Anthropic, and Nvidia, analysts had raised revenue forecasts for AWS.

The firm now expects AWS revenue to grow 28% year-over-year in Q1 2026, 29% for the full year, and 37% in 2027. Analysts believe AI-related workloads will generate about 58% of AWS’s incremental revenue in 2026, rising to 72% in 2027.

Fourteenth place, Arm Holdings, surged 16.38%, with a trading volume of $4.64B. The company announced that its newly released self-developed chip will generate $15 billion in revenue by 2031.

The UK-based semiconductor and software design firm unveiled its first self-developed chip, the AGI CPU, at an event in San Francisco on Tuesday. The chip is designed for AI inference in data centers, with rising demand for CPUs driven by the rise of generative AI.

Arm CEO Rene Haas stated that the new chip is expected to generate $15 billion in revenue by 2031, with the company’s annual revenue reaching $25 billion and earnings per share at $9. This revenue projection is six times its 2025 annual revenue of $4 billion.

Fifteenth place, Intel, up 7.08%, with a trading volume of $4.51B. Reports indicate that AMD and Intel are facing more severe CPU supply issues, adding further pressure on PC and server manufacturers already affected by storage chip shortages.

A study shows that tightening CPU supplies are causing problems across the entire hardware supply chain, including companies involved in PCs, enterprise servers, and related components. The additional pressure makes it harder for manufacturers relying on stable processor and memory chip supplies to plan production and meet delivery deadlines.

Current supply constraints are significant because CPUs remain core components of consumer and enterprise systems. If shortages at Intel or AMD persist long-term, they could impact major equipment manufacturers and cloud infrastructure providers, especially amid ongoing demand related to AI workloads, enterprise upgrades, and PC refresh cycles.

Seventeenth place, TSMC, rose 1.31%, with a trading volume of $4.2B. Recently, Broadcom issued a rare warning, stating that its key manufacturing partner TSMC’s capacity is nearing its limit.
