Investors of nvidia (NVDA.O) may feel more excited about the sales data of its key supplier taiwan semiconductor (TSM.N).

In Wednesday's trading, nvidia's stock price was just a few dollars away from its historical high. Recent multiple increases have brought it close to the historical closing high of around $135 in June (adjusted for stock splits). On Wednesday, nvidia's stock price fluctuated between gains and losses, ultimately falling by 0.2% to close at $132.65, following a 4.1% increase the previous day.

Earlier on Wednesday, nvidia's key supplier taiwan semiconductor announced a 40% year-on-year growth in September sales, becoming a potential factor driving the stock price. Taiwan Semiconductor's total sales revenue for the third quarter reached NT$759.69 billion, approximately $23.58 billion, in line with previous expectations.

Taiwan Semiconductor and nvidia have been working hard to meet the demand for ai chips. Taiwan Semiconductor confirmed plans to double its advanced packaging capacity (known as CoWoS) by the end of 2024, a necessary technology to manufacture nvidia's highest-performance AI chips.

Investors seem to no longer worry about potential delays in shipping nvidia's Blackwell AI chips, but are instead focusing on the company's continued investment capabilities in AI technology.

JPMorgan analysts wrote in a report on Tuesday: "It is expected that nvidia's revenue will reach $175 billion next year and increase to $225 billion by 2027. Considering the entire technology hardware supply chain, research and development, and other operational costs, the total AI expenditure may reach approximately $1 trillion."
