Twelve months ago, the narrative around Google was one of existential anxiety. ChatGPT had blindsided it. OpenAI was eating its lunch. Search was supposed to be dying. Sundar Pichai was under pressure. The company that invented the transformer architecture underlying modern AI was somehow losing the AI race.

Today, that narrative has been comprehensively reversed — and the market has repriced accordingly. Over the past year, Alphabet has gone from an artificial intelligence afterthought to the one firm in the market with dominant positions in nearly every aspect of the technology. Now it is on the brink of overtaking AI chip giant Nvidia as the largest company in the world.

Alphabet's market capitalisation stood at $4.81 trillion as of May 7, 2026, second only to Nvidia at $5.05 trillion. The Class C shares closed at $395.14, brushing against a 52-week high — a stock that has gained 160% in the previous twelve months.

THE QUARTER THAT CHANGED EVERYTHING

The catalyst was an earnings report that left Wall Street scrambling to revise its models upward.

Q1 FY2026 revenue reached $109.90 billion, up 21.8% year-on-year and beating the $107.03 billion consensus estimate by 2.67%. EPS landed at $5.11 versus the $2.63 consensus — a 94% beat. Operating income reached $39.70 billion at a 36.1% operating margin.

The headline number that most rattled Nvidia investors was in the cloud division. Google Cloud crossed $20 billion in quarterly revenue for the first time, growing 63%. The cloud backlog nearly doubled quarter-on-quarter to more than $460 billion. That backlog is not speculative — it is contracted demand that will convert to revenue over multiple years, providing a level of earnings visibility that most technology companies can only aspire to.

Capital expenditure more than doubled to $35.67 billion, and the dividend rose 5%. Analyst consensus earnings estimates for Alphabet's 2026 net income rose approximately 19% in the past month alone, with 2027 expectations up more than 7%.

THE AI STACK NO ONE ELSE HAS

What the market is repricing is not just one strong quarter — it is the recognition that Alphabet has assembled an AI competitive position that no single rival can match.

Gene Munster, managing partner at Deepwater Asset Management, stated that Google spans chips, models, infrastructure, and distribution channels, and its profitability is also very strong. That full-stack positioning is the critical distinction. Nvidia dominates chips. Microsoft dominates enterprise software through OpenAI. Meta dominates social AI. But none of them own the entire chain from silicon to search to cloud to consumer applications the way Alphabet does.

Alphabet is expected to generate approximately $3 billion of revenue from TPU-related infrastructure in 2026 and $25 billion in 2027, according to Citizens analyst Andrew Boone. The TPU chip business — which Sundar Pichai confirmed will soon be available for Google Cloud clients to run in their own data centres — represents a genuine and growing threat to Nvidia's dominance in AI compute. When one of Nvidia's largest customers starts winning business by offering its own chips as an alternative, the competitive dynamic shifts materially.

Pichai opened Google Cloud Next 2026 by announcing a $240 billion backlog and 750 million Gemini users, framing the company's AI strategy as the integration of model, runtime, silicon, and distribution into a single platform. The Gemini agent strategy — built on inter-agent communication protocols and a $750 million partner fund for agentic AI deployments — is designed to make Google Cloud the default infrastructure for enterprise AI. If that bet pays off, the cloud business alone could be worth more than most standalone technology companies within two years.

NVIDIA'S STUMBLE NARROWED THE GAP

The proximity of the two valuations owes something to Alphabet's strength — and something to Nvidia's wobble. At the same time Alphabet surged, Nvidia fell more than 6% in two days following a Wall Street Journal report that business partner OpenAI missed internal revenue and growth estimates. The fall was not about Nvidia's own fundamentals — the company reported $68.1 billion in revenue for its most recent quarter, with data centre revenue up 75%, and its May 20 earnings report is expected to show approximately $78 billion in revenue. But in a market where narrative and sentiment move as fast as fundamentals, the OpenAI miss introduced doubt — and Alphabet's results removed it simultaneously on the other side.

The gap between the two has narrowed considerably over the past six months, including a 34% gain for Alphabet in April alone — its best monthly performance since 2004.

THE VALUATION QUESTION

The bull case is compelling. The cautionary note is equally worth hearing.

Alphabet shares now trade at 28 times estimated earnings — hardly a dot-com-era nosebleed, but well above the company's 10-year average of less than 21 times and near its highest multiple since 2008. The biggest risk, as Munster noted, is that investor expectations have nearly peaked, making it difficult to shift market sentiment with a new narrative. To continue exceeding expectations, Google needs to further clarify its Gemini agent strategy and demonstrate a clear path to sustained monetisation from the broader AI ecosystem.

Prediction markets assign a 29.5% probability to Alphabet ranking first by December 31, 2026 — up from 23.5% on May 7, reflecting a tightening race, but still suggesting a majority view that Nvidia holds the crown through year-end. Analyst consensus sits at $398 with 47 buys and 13 strong buys, and zero sell ratings.

The race between Alphabet and Nvidia is ultimately a debate about where the most durable AI value accumulates — at the chip layer, where Nvidia sits, or at the platform and application layer, where Alphabet is now firmly re-established. The market has not yet given its final verdict. But the direction of travel, twelve months after Google was written off as an AI casualty, is unmistakably clear.
