Adds background in paragraph 2, shares move in paragraph 3

June 5 (Reuters) - Meta META.O is considering raising tens of billions of dollars in a stock offering as it seeks new sources of capital to fund the company's AI ambitions, the Financial Times reported on Friday.

The report comes after Alphabet GOOGL.O moved to raise $84.75 billion in upsized equity offerings, as Big Tech competes to build data centers and capitalize on growing demand for AI.

Meta shares were down 6.6% following the report.

Executives at Meta have been exploring "creative" ways to raise cash as it prepares to sharply boost its AI-related capital expenditures to as much as $145 billion this year and even higher in 2027, the FT report said, citing three people familiar with the plans.

The company did not immediately respond to a Reuters request for comment.
