Nvidia eclipsed Google parent Alphabet as the third most valuable US company on Wednesday, just after overtaking Amazon and as investors looked to the dominant AI chip maker’s upcoming quarterly report.

The Santa Clara, California company’s stock rose 2.46%, putting its value at $1.825-trillion (R34.8-trillion), while Alphabet’s stock climbed 0.55%, leaving it with a value of $1.821-trillion.

Nvidia has been a top beneficiary of technology companies’ race to build AI into their products and services, and the latest gain in its stock came a day after it ended a session with a market capitalisation above Amazon’s for the first time in two decades.

Amazon’s market capitalisation was $1.776-trillion after its stock rose 1.39% on Wednesday.

Nvidia controls about 80% of the high-end AI chip market, a position that has boosted its stock price 47% this year after it more than tripled in 2023. Customers face shortages of Nvidia’s top-of-the-line components while AI developers face months-long waiting lists to use its processors through cloud computing providers.

Technology-related companies, including Microsoft and Meta Platforms, have also rallied to record highs on AI optimism.

Nvidia’s quarterly report next Wednesday will be among Wall Street’s most closely watched of the week. Analysts expect another blowout quarter and outlook, and anything less could deflate Wall Street’s AI rally, some investor warned.

“The market recognises Nvidia as the AI king. But if Nvidia has one bad quarterly report, if they don’t overly exceed investors’ expectations, this thing could sell off 20% or 30% in one after-hours session,” said Jake Dollarhide, CEO of Longbow Asset Management in Tulsa.

Tripling

Susquehanna analyst Christopher Rolland on Wednesday increased his price target for Nvidia’s stock to $850 from $625, saying he expects strong quarterly results and guidance. Nvidia shares were last at $739.

An early leader in the AI race, Microsoft in January overtook Apple to become the world’s most valuable company, now valued at over $3-trillion. State oil giant Saudi Aramco is the world’s third most valuable publicly listed company, according to LSEG.

Analysts, on average, see Nvidia’s January fiscal quarter revenue more than tripling to $20.37-billion, fuelled by demand for its top-shelf AI chips, according to LSEG data. Analysts see its adjusted net profit surging over 400% to $11.38-billion.
