Google’s stock plummeted 7.5% on Wednesday, May 7th, 2025 – its largest single-day drop in years – triggered by comments from Apple. A Bloomberg report revealed Apple services head Eddy Cue’s perspective that AI-powered search engines are poised to supplant traditional search engines like Google. This news sent a tremor through the market, underscoring investor anxiety regarding a potential disruption to Google’s foundational search business. That tells you just how sensitive investors are to one terrifying idea: Search is no longer untouchable.
A Crack In The Core
What happens to Alphabet if Search is no longer dominant? Could we be looking at a scenario where the tech giant’s stock faces a potential 40% downside? Let’s delve into the underlying factors to understand this potential scenario.
Clearly, GOOG stock is volatile, and if you are looking for potential upside with less volatility than a single stock, consider the High-Quality portfolio, which has outperformed the S&P 500 and delivered returns exceeding 91% since its inception.

Google’s Business Model: The Search Empire
Alphabet’s business fundamentally revolves around its search dominance. Approximately 76% of Alphabet’s revenue comes from advertising, which translated to $265 billion out of $350 billion total revenue in 2024. This breaks down as:
- Google Search & Other: $198 billion (main contributor to ads)
- YouTube Ads: ~$46 billion
- Google Network: ~$30 billion
Search isn’t just any revenue stream—it’s the crown jewel that funds everything else in Alphabet’s ecosystem, from Waymo to Google Cloud and countless moonshot projects. The problem is simple: if Search falters, the entire house of cards could collapse.
The Valuation Set-Up: How the Market Prices Google Today
Alphabet currently commands impressive market metrics:
- Market Cap: ~$2.0 trillion
- Trailing Twelve Months P/E: ~17x
- Enterprise Value/EBITDA: ~14x
- Free Cash Flow Yield: ~3.8%
These multiples exist primarily because investors believe in the durability of Google’s search monopoly and its consistent growth trajectory. But these assumptions rest on increasingly shaky ground. If growth slows or margins compress, the valuation math changes dramatically—and not in Google’s favor.
Apple’s AI Threat: A Real Disruption Signal
Apple’s recent emphasis on AI integration isn’t just another routine tech announcement; it suggests a fundamental change in how users could access information. By deeply embedding Siri and ChatGPT-like AI capabilities directly within iOS, Apple is forging a direct route for users to obtain information, potentially circumventing Google altogether.
Consider this: if users can readily obtain answers from their iPhone’s lock screen or through Siri without needing to open a browser, Google’s role in the information access process diminishes significantly. This threat isn’t isolated. Concurrent advancements in platforms like ChatGPT, Perplexity AI, and Microsoft’s Bing Copilot are also establishing alternative pathways for information discovery.
The most immediate and concerning consequence for Google is the potential for a decline in search referral traffic originating from iPhones. This impact could realistically begin to materialize within the next 12 to 24 months.
What if Google Search Declines? A Stress-Test Analysis
Revenue Impact:
Let’s consider a stress-test scenario where AI disruption leads to a 15-20% decrease in Google Search revenue over the next 2 to 3 years. This would translate to a significant annual revenue reduction of $40 to $60 billion for Alphabet. Simultaneously, to remain competitive in the AI landscape, Alphabet will likely face increasing infrastructure costs, particularly for TPUs and inference. This combination of reduced revenue and higher costs could compress Alphabet’s operating margins from the current 32% down to around 26%.
Valuation Implications:
The more substantial impact, however, could stem from valuation compression. If the market’s perception shifts and it no longer views Search as an invulnerable business, Alphabet’s price-to-earnings (P/E) ratio could contract from its current 17x to approximately 12x-14x. When this P/E compression is coupled with lower earnings due to the revenue decline and margin pressure, the total potential downside for Alphabet’s stock ranges from 35% to 40%.
Market Perception and Value Erosion:
Even before any actual financial collapse occurs, a change in market sentiment regarding the untouchability of Search could lead to a significant erosion of Alphabet’s market capitalization. A 35-40% decline would equate to a potential loss of around $800 billion in valuation for the company.
Historical Precedents: The Decline of Once-Dominant Tech Companies
History offers cautionary tales of tech giants faltering in the face of significant platform shifts. Microsoft, despite its dominance in computing, was slow to adapt to the rise of the internet and mobile, losing its central position. Intel, once seemingly unassailable, found its market challenged when Apple’s custom silicon revealed its relative stagnation. Similarly, IBM’s reign in enterprise computing waned as the cloud rendered its hardware-focused strategy less critical.
These examples illustrate a recurring pattern: dominant companies that failed to effectively navigate fundamental changes in computing paradigms didn’t just experience a decrease in market share – they risked becoming less relevant in the evolving technological landscape. Is Google positioned at a similar inflection point today?
What to Watch: The Slow-Motion Unraveling?
Several indicators will signal whether this threat is materializing:
- iOS 18 adoption rates and Siri usage data
- Changes to Google’s Traffic Acquisition Cost (TAC) payments to Apple
- Chrome usage trends versus AI-native platforms
- Advertiser spend shifts toward AI-native ad placements
Each of these metrics provides visibility into whether Google’s search moat is holding or beginning to crumble.
Conclusion: Is This Google’s “iPhone Moment” — but in Reverse?
The current market reaction isn’t merely about a disappointing quarter or temporary headwinds. It reflects growing concern about whether the next computing paradigm – centered around conversational AI – fundamentally sidelines Google.
Google built its empire on organizing the world’s information through traditional search. If that model becomes obsolete, the company could transform from a reliable growth compounder into a value trap almost overnight. The 7.5% stock drop might just be the beginning of a more significant revaluation as investors wrestle with this existential question.
What made the iPhone so revolutionary wasn’t just the device itself but how it reshaped the technology landscape. Google now faces a similar moment – but instead of being the disruptor, it risks becoming the disrupted.
For investors aiming to reduce the inherent volatility associated with individual stocks like Google, there are alternative investment strategies available. The Trefis RV strategy, which has a history of outperforming its all-cap stock benchmark, provides a diversified approach to potentially achieve solid returns. Likewise, the High-Quality portfolio has shown superior performance compared to the S&P 500 with returns that exceed 91% since its initiation, offering potential upside with reduced stock-specific risk.
