The AI Build-Out Meets the Cash Register: Amazon and Alphabet Post Negative Free Cash Flow

Investors spent two years rewarding every dollar the biggest tech companies announced for AI. In 2026 they began reading the other side of the ledger.

• Alphabet’s long-term debt grew 111 percent to $98 billion and Amazon’s rose 81 percent to $119 billion, and both reported negative free cash flow for the first time ^[1].
• Alphabet raised the top of its 2026 capital spending range to $205 billion, Microsoft guided to $190 billion and Meta to between $138.9 and $145 billion ^[1].
• Amazon’s guidance stood at $200 billion, with consensus near $207.4 billion after Alphabet’s report ^[1].
• Alphabet shares fell 7 percent after its July 24 announcement ^[1].

The spending guidance

After the second-quarter reports, the guidance for 2026 capital spending looked like this, according to a Digital Today analysis: Alphabet raised the top end of its range to $205 billion; Microsoft guided to $190 billion in capital expenditures and finance leases, including about $25 billion tied to higher component prices from AI chip demand; Amazon held its $200 billion figure from April, with consensus rising to about $207.4 billion; and Meta guided to between $138.9 billion and $145 billion ^[1].

What it cost the balance sheet

The financing shows. Alphabet’s long-term debt rose 111 percent to $98 billion, and Amazon’s rose 81 percent to $119 billion. Both companies reported negative free cash flow for the first time ^[1]. Free cash flow is operating cash minus capital spending, a measure of what is left for buybacks, dividends or debt repayment. When it turns negative, a company is funding growth with borrowing.

The market’s reaction

Alphabet shares fell 7 percent after the July 24 capex announcement, with Amazon, Meta and Microsoft also declining. As the analysis puts it, markets had treated AI infrastructure spending as a growth signal and have recently begun to weigh the cash drain against uncertain returns more closely ^[1].

What analysts and the filings said

Evercore ISI’s Mark Mahaney was quoted saying that Alphabet’s higher capital spending raises the likelihood that Amazon and Microsoft will make similar decisions ^[1]. The cash-flow turn was new for both companies: Alphabet’s free cash flow turned negative in the second quarter for the first time, while Amazon’s turned to a deficit in the first quarter with an annual deficit expected ^[1]. Amazon’s debt rose 81 percent to $119 billion between December 31, 2025 and March 31, 2026, and Alphabet’s rose 111 percent to $98 billion in the first half of 2026 ^[1].

The revenue side is why the spending continues. Google Cloud revenue grew 82 percent in the second quarter, its fastest pace since at least 2020; AWS grew 28 percent in the first quarter with about 32 percent estimated for the second; and Microsoft’s Azure and cloud services grew 40 percent in the first quarter with about 39 percent estimated for the second ^[1]. Meta, meanwhile, was reported to be exploring selling computing power externally alongside its $138.9 to $145 billion capital plan ^[1]. The market’s question is whether revenue growth of this kind can repay the debt and the depreciation that follow such large builds.

How to think about it

Heavy investment is not a mistake in itself; it is how infrastructure gets built. The question is the return: whether AI revenue grows fast enough to pay for the capacity. One piece of encouraging evidence is cloud growth, with Google Cloud reported up 82 percent in the second quarter ^[1]. One cautionary piece is leverage, which magnifies both the upside and the pain. Watch free cash flow and debt as closely as you watch revenue growth. This is analysis, not investment advice.
