Why is Alphabet stock climbing today?

Alphabet stock surged 2.4% in pre-market trading, reaching $355.59 after an investment firm's analyst boosted his price target. Evercore analyst Mark Mahaney raised his target from $420 to $450 and maintained a Buy rating. The upgrade was based on new proprietary data showing Google's search engine dominance is strengthening, with 78% of respondents naming it their primary search engine in August 2026, up from 70% in 2024 and 2025.

The analyst also revised his growth forecasts for Google's search revenue, projecting 4% to 5% above Wall Street expectations for 2028. Meanwhile, a separate firm raised its price target for the shares to $485, signaling a broader institutional consensus shift. The favorable reaction follows a U.S. federal judge's decision on September 16 not to force Google to divest its advertising technology business, instead requiring only minor ad bidding rule changes and the appointment of an internal compliance monitor.

This outcome was viewed as significantly less severe than the complete breakup the government had sought. Additionally, a credit rating analysis affirmed Alphabet's ability to fund its AI infrastructure investments through 2028. The NASDAQ and S&P 500 were modestly up in pre-market trading, but Alphabet's gain stood out, indicating a company-specific catalyst rather than a market-wide move.

With GOOGL still below its 52-week high of $408.61, further upside remains possible if the analyst sentiment continues to strengthen.
