Chip stocks surge after TSMC boosts outlook on soaring AI demand

/in /tarafından

Global semiconductor stocks rose on Thursday after Taiwan Semiconductor Manufacturing Co (TSMC) issued a strong revenue forecast and reported record quarterly profits, underscoring surging demand for chips that power artificial intelligence systems.

TSMC — the world’s largest contract chipmaker and a key supplier to Nvidia and Apple — raised its full-year revenue guidance to mid-30% growth, up from around 30%, citing stronger-than-expected AI spending and data center expansion. Analysts say this marks a shift from a cyclical boom to a structural uptrend driven by AI infrastructure demand.

“This isn’t just a transient spike. TSMC’s blowout quarter tells a clear story — this is structural,” said Kate Leaman, chief market analyst at AvaTrade.

The upbeat forecast sent semiconductor stocks higher worldwide. Micron Technology gained about 4%, Broadcom climbed 2.4%, Marvell Technology added 1.3%, and Nvidia rose 1.2%. In Asia, Samsung Electronics advanced 2.8%.

The rally came amid a week of massive AI-related deals, including BlackRock’s $40 billion acquisition of data-center operator Aligned and a partnership between OpenAI and Broadcom to build 10 gigawatts of custom chips — enough to power more than eight million U.S. homes.

The developments reinforce Wall Street’s conviction that AI hardware remains the core driver of tech investment, nearly three years after ChatGPT’s debut. On Wednesday, Salesforce also projected revenue above $60 billion by 2030, driven by rapid AI integration across its cloud services.

TSMC lifts revenue forecast on surging AI chip demand after record profit

/in /tarafından

Taiwan Semiconductor Manufacturing Co. (TSMC), the world’s largest chipmaker, raised its full-year revenue forecast after reporting a record quarterly profit, citing booming demand for artificial intelligence chips. The results reinforced investor confidence in the AI megatrend, which continues to drive growth across the semiconductor industry despite fears of overheating.

TSMC said it now expects 2025 revenue to grow in the mid-30% range in U.S. dollar terms, up from its previous forecast of around 30%. The company maintained its capital expenditure outlook at up to $42 billion for 2025. “AI demand continues to be stronger than we expected three months ago,” CEO C.C. Wei told analysts, adding that customer requests for expanded capacity remain high.

The company’s robust performance comes amid a flurry of billion-dollar partnerships between AI developers and chipmakers, including OpenAI’s collaborations with Nvidia, AMD, and Broadcom to build massive data center capacity. TSMC manufactures chips for all three, as well as for Apple.

In the July–September quarter, TSMC’s net profit surged 39.1% year-on-year to T$452.3 billion ($14.76 billion), easily beating market expectations of T$417.7 billion. Wei said the company remains confident that demand for leading-edge semiconductors is “real” and will continue through 2026, despite geopolitical uncertainties and potential U.S. tariffs on chip imports.

TSMC shares have risen 38% this year, far outpacing Taiwan’s broader market, as the company cements its dominance in the global AI supply chain.

Broadcom unveils Thor Ultra networking chip to challenge Nvidia in AI data centers

/in /tarafından

Broadcom has launched its new Thor Ultra networking chip, designed to help companies build massive artificial intelligence computing systems by linking together hundreds of thousands of processors — escalating its rivalry with Nvidia in the race to dominate AI infrastructure.

Unveiled on Tuesday, the Thor Ultra chip enables data center operators to connect far more AI processors than before, making it easier to train and deploy large models like OpenAI’s ChatGPT. The launch follows Broadcom’s announcement on Monday of a major deal to deliver 10 gigawatts of custom chips for OpenAI starting in 2026, further challenging Nvidia’s dominance in AI accelerators and networking technologies.

“The network plays an extremely important role in building these large clusters,” said Ram Velaga, Broadcom’s senior vice president. “So I’m not surprised that anybody in the GPU business wants to participate in networking.”

AI has become a $60 billion to $90 billion market opportunity for Broadcom by 2027, according to CEO Hock Tan, split between networking chips and custom data center processors built for companies such as Google and OpenAI. In 2024, Broadcom reported $12.2 billion in AI revenue, and in September it disclosed a $10 billion unnamed customer for its AI chips.

The Thor Ultra doubles the bandwidth of its predecessor and acts as a vital link between AI systems and the rest of the data center, improving data transfer speeds and scalability. Engineers developed it alongside Broadcom’s Tomahawk networking switches, refining every detail from power consumption to thermal management.

While Broadcom does not sell servers directly, it provides reference designs for partners to build upon. “For every dollar we invest in our silicon, our ecosystem partners invest six to ten times more,” Velaga said, emphasizing the company’s design-first strategy in the AI infrastructure market.
