In Short: Google parent Alphabet's market value fell nearly $500 billion after its shares dropped 12.64% following disappointing third-quarter earnings.

Alphabet's Class A shares closed at $283.82, down 12.64%, wiping approximately $499.8 billion from the company's market capitalization, according to Fox Business.
Alphabet's capital expenditures are expected to reach between $195 billion and $205 billion this year, with spending projected to increase significantly in 2027, according to previous Fox Business reporting.
The sell-off followed Alphabet's third-quarter earnings report, which heightened investor concerns about the company's massive spending on artificial intelligence and slowing growth in its core search advertising business.
Alphabet's largest division, which includes search advertising, grew 12% year on year, reaching $63.4 billion in revenue.
The Nasdaq fell over 2% at the open as tech giants like Amazon, Google, Intel, and Alphabet suffered heavy drops, with the index falling over 5.8% so far in October.
According to S&P Global Market Intelligence, Microsoft, Alphabet, Amazon, Meta, and Oracle raised a combined $326 billion in debt in 2026, triple the amount raised last year.
Alphabet's stock fell about 8% in extended trading as investors weighed accelerating infrastructure spending against the returns it is producing.
