Google Antitrust Ruling Sparks Tech Rally as AI Market Dynamics Shift

Alphabet surged 9% in a single session after US District Judge Amit Mehta delivered a narrower-than-expected remedy in Google's antitrust case. The ruling requires data sharing with rivals but preserves Core business structures, including Apple's lucrative search default deal. Tech stocks added $420 billion in market value over three days as the decision removed regulatory uncertainty.

The verdict acknowledges generative AI's disruptive impact, naming OpenAI, Anthropic and Perplexity as emerging competitors reshaping search economics. Wedbush analysts highlight potential for expanded Apple-Google collaboration on AI integration, particularly around Alphabet's Gemini model. This follows Broadcom's newly announced OpenAI partnership, signaling intensified AI infrastructure competition.

While the DOJ's multi-year campaign against Big Tech continues, markets interpreted the ruling as avoiding worst-case scenarios for platform companies. The Nasdaq climbed 1.1% on the week as investors reappraised tech valuations under evolving regulatory and technological landscapes.
