This figure helps assess Amazon's true profits
A key indicator of a company's profitability is free cash flow (FCF), which is the money a business has remaining after operating expenses and capital expenditures. It's the cash left after what's used to run and grow a company.
Amazon reported negative FCF in 2021 and 2022. But things improved drastically after, with FCF totaling $36.8 billion in 2023 and $38.2 billion in 2024.

Artificial intelligence will continue to be a major use of cash
As are its peers, Amazon is spending aggressively on artificial intelligence (AI) efforts. It plans to spend $125 billion on capital expenditures just this year.
Wall Street consensus analyst estimates call for FCF to dip 45% year over year in 2025. Investors will want to see FCF return to growth sooner rather than later, as this might show that all the AI-related capital outlays are starting to bear fruit.
