Alphabet’s search empire is facing its first real stress test in years. The company pulled in $67 billion in ad revenue during Q1 2025, and nearly 74% of that came from Search. That’s not a side hustle. That’s the engine. And the engine runs through Chrome. According to DOJ filings in the ongoing antitrust case, 35% of all Google search queries originate inside Chrome. That browser isn’t just a portal. It’s a pipeline for billions in ad dollars.
The problem is that pipeline is now under threat. OpenAI is weeks away from launching its own browser. Perplexity’s Comet is already in public beta. Both are designed to intercept search behavior and reroute it through AI-native interfaces. Barclays estimates that a 5-point drop in Chrome’s market share could shave more than $3 billion off quarterly Search revenue. That’s not theoretical. That’s a direct hit to Alphabet’s core.
Chrome still holds the crown. Global share sits near 68%. Edge trails at 13%. But the DOJ’s antitrust ruling in August could force structural changes. If Chrome is decoupled from Google Search, the ad funnel narrows. Alphabet knows this. That’s why Gemini is being pushed hard. The AI model is now embedded across Chrome, Gmail, Docs, and Android. It’s not just a chatbot. It’s a retention strategy.
Historically, only 20% of Google searches were monetizable. With AI-driven personalization and intent inference, that funnel is expanding. Gemini’s integration is designed to boost monetization rates by surfacing ads tied to inferred needs, not just keywords. That’s the pivot. Alphabet isn’t just defending its moat. It’s deepening it.
The stock dropped 15% from its recent high. Alphabet posted double-digit top-line growth and a 34% operating margin in Q1. But the market is pricing in forward risk. GOOG now trades at roughly 17 times forward earnings. That’s a discount for a company with $2.16 trillion in market cap and a dominant position in both search and browser infrastructure.
The AI race is noisy. Sentiment flips weekly. But Gemini is never last. And Google’s browser footprint is still unmatched. The real catalyst is the antitrust ruling in August. Until then, the threat is real, but the moat is holding.
