Quick overview

---

Alphabet surpassed Apple Inc. to rise to the second-most valuable company in terms of market capitalization, demonstrating how the parent company of Google has become one of the biggest beneficiaries of artificial intelligence.

Alphabet’s stock increased by 2.4 percent on Wednesday, closing at a valuation of $3.89 trillion. It was able to overtake Apple, which ended Wednesday with a market capitalization of $3.85 trillion after a six-day decline that erased nearly 5% of its value, or $200 billion.

The difference grew even more on Thursday with Apple opening 1.2 percent lower and Alphabet rising 1.1 percent. Since 2019, Alphabet has not surpassed Apple in size. NVIDIA Corp. continues to be the biggest stock, with a valuation of $4.6 trillion.

Alphabet is currently the best-performing of the Magnificent Seven, with shares rising more than 65% since 2025.

The increasing perception that Alphabet is well-suited in many important areas of AI accounts for a large portion of its strength.

Concerns about competition from businesses like OpenAI were allayed by positive reviews for the company’s most recent Gemini AI model, and its tensor processing unit chips are thought to be a major factor in future revenue growth.
