Why Alphabet (Google) Stock Fell Over 7%: Antitrust Fears, AI Pressure, and Apple’s Surprise Move

Alphabet Inc. (NASDAQ: GOOG, GOOGL), the parent company of Google, witnessed a sharp sell-off on May 7, 2025, with its shares dropping over 7% intraday. The stock plummeted from a previous close of $165.20 to an intraday low of $153.30, erasing billions in market capitalization. While Big Tech stocks often face market volatility, the magnitude and timing of this decline point to a convergence of structural challenges, regulatory risks, and competitive threats.

This article explores the key reasons behind the fall, examines investor sentiment, and discusses what lies ahead for Alphabet and its shareholders.

Antitrust Ruling Triggers Shockwaves

One of the most immediate triggers for the stock’s decline is the latest development in Alphabet’s long-standing antitrust battle with the U.S. Department of Justice (DOJ). A federal judge recently ruled that Google unlawfully maintained monopolistic control over parts of the digital advertising ecosystem — particularly its dominance in the ad exchange market and ad management tools.

In response, the DOJ is now seeking a forced breakup of Alphabet’s advertising technology stack. Specifically, regulators want Alphabet to divest:

  • Google AdX – its dominant ad exchange platform
  • Google DFP – its DoubleClick for Publishers ad server

This would represent the most significant structural blow to Google’s advertising business in its history. While appeals and legal defenses could delay execution, investors are pricing in long-term damage to the company’s cash cow — digital advertising — which still constitutes over 75% of Alphabet’s revenue.

Analysts warn that if regulators succeed, it could reduce Alphabet’s ad revenue, increase operational inefficiencies, and expose it to further scrutiny in international markets such as the EU and India.

Apple’s AI Search Experiment Spooks Investors

In an equally disruptive development, reports surfaced that Apple is actively exploring AI-powered search alternatives for its Safari browser. According to insiders, Apple has held discussions with emerging AI startups like Perplexity and Anthropic, testing the possibility of integrating AI-driven search tools that could eventually replace Google as the default search provider on iPhones and Macs.

This is no small risk. Google reportedly pays Apple $18 billion to $20 billion annually to remain the default search engine across Apple devices. Losing that deal could create a major earnings hole and shake confidence in Google’s search moat.

Moreover, Apple’s move signals a broader trend of platform players diversifying away from Google and exploring AI-native interfaces, which could disrupt the search industry at its core.

Massive AI CapEx Raises Red Flags

Alphabet has been aggressive in positioning itself as a leader in the AI arms race, competing with Microsoft (via OpenAI), Amazon, Meta, and others. In Q1 2025, U.S. hyperscalers — including Alphabet — collectively spent over $81 billion on AI-driven data centers, model training infrastructure, and chips. Alphabet’s share of this spending is believed to be among the largest, with heavy investments in:

  • Tensor Processing Units (TPUs)
  • Data center expansions
  • AI model development (Gemini series)
  • Cloud-based AI APIs for enterprise clients

While these investments promise long-term AI leadership, Wall Street is split. On one hand, bulls argue that Alphabet’s AI tools will unlock new monetization paths in search, cloud, and productivity. On the other, bears warn that unchecked spending could compress margins if monetization lags behind costs — especially in a slower macro environment.

Increased capital expenditure (CapEx), when paired with declining margins or weak guidance, often triggers negative market reactions — as seen today.

Market Reaction and Valuation Picture

The stock’s dramatic fall also reflects broader sentiment. Investors were already cautious following Q1 earnings, which, while strong, came with elevated CapEx guidance and no major upside surprises. The regulatory and competitive threats simply accelerated the correction.

As of May 7:

  • Previous Close: $165.20
  • Intraday Low: $153.30 (over 7% drop)
  • PE Ratio: ~16.9
  • EPS (TTM): $9.15
  • Market Cap: ~$1.87 trillion

Despite the fall, Alphabet’s valuation remains relatively attractive compared to peers like Microsoft and Amazon, especially if its AI bets pay off. But the uncertainty introduced by the antitrust case and Apple’s strategic shift is making investors reconsider the “safe Big Tech” narrative.

Analyst Views: Is This a Buy-the-Dip Moment?

Several analysts issued mixed reactions:

  • Morgan Stanley reiterated an “Overweight” rating but lowered the price target, citing regulatory overhang as a medium-term concern.
  • JPMorgan noted that Alphabet remains “a structural long-term winner in AI and search,” but advised clients to expect volatility in the coming quarters.
  • Bernstein analysts warned that the Apple-Perplexity tie-up, if it materializes, could “break the back of Google’s iPhone search dominance,” making the scenario more than just theoretical risk.

In short, while the fundamentals remain solid, the narrative has shifted from dominance to defense.

What Lies Ahead: Strategic Crossroads

Alphabet finds itself at a strategic inflection point. Here’s a breakdown of the key forward-looking themes investors should watch:

1. Antitrust Outcome

  • If Alphabet is forced to divest its ad-tech business, the company will need to reorient its monetization strategy across YouTube, Search, and Cloud.
  • The case also sets precedent for future tech regulation, both in the U.S. and abroad.

2. Apple’s Next Move

  • The tech world is closely watching Apple’s WWDC in June 2025 for any announcement regarding its search engine partnership.
  • If Apple confirms a shift away from Google, a major stock re-rating could follow.

3. AI Monetization Pace

  • Alphabet’s Gemini AI models are being integrated into Google Search, Workspace, and Cloud — but actual revenue contribution remains murky.
  • Investors need clearer signals on ROI and pricing of AI products.

4. Cloud and YouTube Resilience

  • Google Cloud and YouTube are seen as strong pillars beyond Search. Growth in enterprise cloud and monetized YouTube Shorts could soften any core business weakness.

Conclusion

Alphabet’s stock decline reflects a perfect storm of structural regulatory risks, competitive AI disruption, and investor sensitivity to high-spending tech narratives. While Alphabet is far from losing its status as a global tech leader, the days of unquestioned dominance — especially in search and advertising — may be numbered.

Investors now face a dilemma: stay long in a quality compounder navigating short-term storms, or wait on the sidelines until regulatory and competitive clouds clear. Either way, Alphabet’s response in the coming quarters will define the next phase of its evolution.
