Alphabet Rises 3% as NVIDIA's Sudden CEO Exit Puts Google TPUs in Focus

Alphabet shares climbed 3% to $301.97 in Thursday trading after NVIDIA's abrupt leadership shake-up pushed investors to reconsider where future AI chip spending could flow. NVIDIA stock fell 6% on the same day. Broadcom, the chipmaker that helps Google design its Tensor Processing Units, gained 5%.

The trigger came on November 12, when NVIDIA (NASDAQ:NVDA) announced that Jensen Huang resigned as president, chief executive officer and board member, effective immediately. Chief financial officer Colette Kress is serving as interim CEO while retaining her finance role, and the board is weighing internal and external candidates for a permanent successor, according to the company.

What does Huang's exit change for AI chip buyers?

NVIDIA's products and existing contracts remain in place through the transition. Harvey Jones, named the board's first-ever chair, stated: "we expect the company's operations, customer commitments and product roadmap to continue without interruption."

Words are one thing. Markets reprice on uncertainty, and the absence of a permanent CEO at the dominant supplier of AI accelerators (the specialized chips that train and run large models) gives rivals a fresh opening. Much of Thursday's buying in Alphabet reflects investor speculation about whether the biggest cloud buyers might look beyond NVIDIA graphics processing units, and Google's in-house TPUs sit closest to hand.

The stakes are large. NVIDIA's GPUs anchor most large-scale AI training today, and any perceived wobble in its execution affects how hyperscalers — the handful of companies operating planet-scale data centers — allocate their capital. Alphabet, Microsoft and Amazon all buy heavily from NVIDIA while developing their own silicon in parallel.

Why did Alphabet gain the most?

Alphabet has the longest track record in custom AI chips among the three cloud giants, and it monetizes that silicon directly. Google rents TPU systems to customers through Google Cloud, turning custom chips into a revenue line as well as an internal cost tool. That gives Alphabet a direct path to benefit if AI buyers diversify away from NVIDIA.

The financial backdrop supports the pitch. Google Cloud revenue rose 103% year over year to $30.71 billion in Q3 2026, results the company reported to the SEC on October 28. CEO Sundar Pichai noted at the time: "We're also seeing strong demand for our TPU systems across a wide range of customers."

Microsoft (NASDAQ:MSFT) and Amazon (NASDAQ:AMZN) trailed Alphabet's move. Microsoft shares stood at $528.98, up 2%. Amazon stock sat at $269.49, up 1%.

How do the three cloud chip strategies differ?

The divergence matters because it determines who captures NVIDIA's shortfall, if any materializes.

• Alphabet sells TPU systems broadly through Google Cloud, pairing merchant sales with internal use.
• Microsoft pairs NVIDIA hardware with its own Maia systems inside Azure, building what CEO Satya Nadella called a "fungible fleet" that moves capacity to the highest-value work.
• Amazon runs most of its Bedrock AI service on in-house Trainium chips and is preparing to sell those chips outside AWS, a model closer to Google's.

Andy Jassy, Amazon's chief executive, said on the company's latest earnings call: "The number of companies who have a significant cloud business and a chip strong enough to sell externally is effectively two." By that count, Alphabet and Amazon form the small group of cloud providers developing merchant AI chips, while Microsoft relies more heavily on NVIDIA.

Is cloud demand strong enough to carry all three?

Yes, by the growth numbers. Azure revenue at Microsoft grew 48% in the quarter ended in September. Amazon Web Services revenue rose 39% over the same stretch. Both figures sit well behind Google Cloud's 103% pace.

A leadership setback at NVIDIA could cut both ways for Microsoft and Amazon, since their data centers lean on NVIDIA hardware even as their in-house chips mature. For Alphabet, the exposure runs the other direction: any buyer hedging away from NVIDIA finds a credible, commercially available alternative in TPU systems already renting at scale.

What are the risks to the Alphabet trade?

The bears have numbers of their own. Alphabet's capital expenditures reached $51.36 billion in Q3, and its free cash flow came in at negative $9.07 billion, figures that show the cost of the infrastructure build-out behind the TPU push. Alphabet is also funding part of that push with debt and at-the-market share sales — a dilutive financing mechanism in which a company sells newly issued stock into the market over time.

Timing adds risk. NVIDIA plans to report its Q3 FY2027 results on November 17, a release that could show whether its customer relationships are holding steady through the transition. Strong results and a quick rebound in NVIDIA stock could cool the speculation currently lifting Alphabet.

For now, the market has rendered a split verdict: NVIDIA down 6%, Alphabet up 3%, Broadcom up 5%. Until NVIDIA's board names a permanent CEO, investors face an open question about who leads the AI chip market's next phase — and Alphabet, with a 103%-growth cloud business and TPUs already on sale, holds the clearest claim to the challenger role.
