Robust performance forecasts issued this week by ASML Holding NV and Taiwan Semiconductor Manufacturing indicate that U.S. cloud computing giants are heading into another quarter of substantial expenditure, as they accelerate purchases of advanced chips required to build artificial intelligence operations.

These outlooks demonstrate that demand remains strong for AI chip designers such as Nvidia, Advanced Micro Devices, and Broadcom, all of which rely on Taiwan Semiconductor Manufacturing, the world's leading advanced processor manufacturer, for supply.

Investors are increasingly pressuring major technology firms like Microsoft, Meta Platforms, and Amazon for clearer returns on their AI investments, raising questions about the sustainability of the chip spending surge. Nevertheless, these companies are still projected to spend over $600 billion in the data center sector this year.

Taiwan Semiconductor Manufacturing's CEO, C.C. Wei, stated during an analyst call, "AI demand is very strong... Our customers, and our customers' customers—primarily cloud service providers—continue to signal extremely strong demand and an optimistic outlook."

On Thursday, Taiwan Semiconductor Manufacturing raised its annual revenue forecast and announced it would increase capital expenditure this year to meet demand for AI chips.

ASML Holding NV, the world's largest supplier of chip manufacturing equipment, also raised its full-year revenue outlook on Wednesday.

Giuseppe Sete, Co-founder and President of investment analysis platform Reflexivity, commented, "Despite concerns about an AI bubble, ASML's optimistic data overall paints a positive picture for the semiconductor industry."

Although overall demand for AI chips remains robust, it is increasingly concentrated on high-end processors. These chips are used to run large language models and apply training results to query-and-answer tasks, known as inference operations.

Capacity Constraints Limit Growth Potential

As demand for AI chips and equipment surges, the industry's heavy reliance on a limited number of suppliers means that chip manufacturers can only fulfill orders if they secure sufficient capacity from these providers.

Consequently, companies are entering into long-term agreements to lock in capacity allocations for the coming years.

ASML CEO Christophe Fouquet indicated that demand is expected to outstrip supply for the foreseeable future, leading to tight capacity across multiple markets, from artificial intelligence to smartphones and personal computers.

Executives at Taiwan Semiconductor Manufacturing also highlighted capacity constraints on Thursday, noting that the company is working at full capacity to expand production for large-scale manufacturing of AI chips.

CEO C.C. Wei stated, "Capacity is very tight, but we are doing our utmost to ensure we meet customer demand... We are increasing capital expenditure to boost capacity."
