Amazon.com Inc reported a $42.4B cash burn in the third quarter on Thursday, sending its shares down 7% in extended trading. The heavy spending on artificial intelligence infrastructure overshadowed the fastest cloud growth the company has seen in five years. Investors reacted cautiously as surging capital expenditures swallowed operating cash flow across the broader tech sector.
