How much of their massive AI infrastructure investment are the big technology companies actually funding from their own operations? A comparison of April–June 2026 results shows that, among Alphabet, Microsoft, Amazon and Meta, only Microsoft and Meta kept capital spending below operating cash flow. In the same quarter, Alphabet raised about $74.4 billion (roughly ¥11.7 trillion) from outside investors through equity and debt issuance. Being a big company does not mean funding all capital spending from core business earnings. On October 26, Taiwan's Economic Daily News reported the view of an unnamed institution that large companies with strong cash flow can keep investing, while heavily indebted operators may be forced to sell assets, raise equity or consolidate. But when the four giants and CoreWeave are compared over the same period on the same basis, what separates them looks less like whether they use outside funding and more like the terms on which they can obtain it.
Can Big Tech Keep Investing in AI on Strong Cash Flow?
On October 26, Economic Daily News, citing the outlook of an unnamed institution, reported that in 2027 the ability to generate returns from AI investment will be tested more severely, and that capital markets will widen the gap in lending terms according to each borrower's financial condition. Large technology companies with abundant cash flow can continue investing, the report said, while heavily indebted AI infrastructure operators may be forced to strengthen their finances through asset sales or equity raises, or to accept industry consolidation. It rated Microsoft as better placed to keep investing than heavily indebted AI infrastructure operators, and also cited Alphabet's sound financial base as a strength.
This outlook does not claim that large companies fund all of their capital spending from their own money. In fact, it credits Microsoft with access to capital markets in addition to abundant cash flow. The basic contrast, however, is between large companies that generate a great deal of cash from their core businesses and AI infrastructure operators that depend heavily on borrowing.
To test that difference, we compare whether each company covered its capital spending within operating cash flow. The subjects are Alphabet, Microsoft, Amazon and Meta, plus CoreWeave, which provides cloud infrastructure for AI. The comparison period is April–June 2026, the quarter for which all companies have reported results.
Only Two of the Four Giants Kept Capital Spending Below Operating Cash Flow
The measure is the "purchases of property and equipment" line in each company's consolidated cash flow statement, divided by operating cash flow. Operating cash flow represents cash generated by core business activity, and purchases of property and equipment show cash spent on data centers and other facilities. A ratio above 100% means the company spent more on acquiring equipment than it earned from operations in that quarter. The calculation does not include capital investment made through leases.
The April–June 2026 results are as follows.
| Company | Operating cash flow | Purchases of property and equipment | Purchases / operating CF |
|---|---|---|---|
| Microsoft | $55.441 billion | $35.802 billion | 64.6% |
| Meta | $31.862 billion | $30.116 billion | 94.5% |
| Alphabet | $39.069 billion | $44.924 billion | 115.0% |
| Amazon | $45.387 billion | $54.208 billion | 119.4% |
| CoreWeave | $0.679 billion | $6.422 billion | 945.8% |
Note: Editorial calculations based on each company's earnings materials. Microsoft's figures are for fiscal fourth quarter 2026. CoreWeave's purchases include capitalized software-related spending. Ratios exclude investment made through leases.
Microsoft devoted 64.6% of operating cash flow to acquiring property and equipment, and Meta 94.5%, both below 100%. Alphabet, at 115.0%, and Amazon, at 119.4%, spent more on equipment than they generated in operating cash flow. For Amazon, the ratio stays above 100% even after deducting $1.132 billion in separately recorded proceeds from equipment sales and similar items. CoreWeave stood out at 945.8%, with equipment purchases far exceeding operating cash flow on a scale well beyond the four giants.
We do not compare the free cash flow (FCF) figures each company publishes because their calculation methods are not uniform. FCF is generally operating cash flow minus capital spending, but what counts as capital spending differs by company. Alphabet and Microsoft subtract purchases of property and equipment; Alphabet's April–June FCF was negative $5.855 billion. Meta also subtracts $962 million in principal payments on finance leases and reports FCF of positive $784 million. Amazon, meanwhile, reported trailing-twelve-month FCF of negative $7.604 billion, reflecting proceeds from equipment sales and incentives, among other items.
Because published FCF differs in method and period, lining the figures up directly makes it hard to tell whether differences reflect business reality or accounting definitions. This comparison therefore uses a single approach: purchases of property and equipment divided by operating cash flow.
That method has limits, however. In particular, Microsoft's 64.6% may not fully reflect the burden of its infrastructure expansion, because it excludes investment through leases. As of June 30, 2026, the company had $329.1 billion (about ¥5.18 trillion) in leases not yet commenced, mainly related to data centers. These leases will begin in stages from fiscal 2027 through fiscal 2033, with terms ranging from 1 to 20 years.
Microsoft plans to extend the useful life of data centers and similar assets from 15 to 25 years starting in fiscal 2027, and says many future data center leases will shift from finance leases to operating leases. On the earnings call, CFO Amy Hood explained that finance leases are included in capital expenditures while operating leases are not. The company's calendar-2026 capital spending outlook has also been lowered from about $190 billion to about $175 billion. If the accounting treatment of leases changes, the amount recorded as capital spending can shrink even when actual facility plans change little.
Alphabet Raised About $74.4 Billion Externally; the Gap With CoreWeave Lies in Funding Terms
Beyond comparing capital spending with operating cash flow, how much outside funding each company raised also matters. Alphabet's cash flow statement for April–June 2026 records $30.499 billion in proceeds from issuing common stock, $19.063 billion from issuing mandatory convertible preferred stock, and $24.847 billion from issuing debt. The total is $74.409 billion, or about ¥11.7 trillion at ¥157.30 to the dollar (HSBC Tokyo's end-of-September 2026 mid-rate). These are gross proceeds from fundraising and do not mean the entire amount went to capital spending.
Alphabet's equity issuance was part of an $80 billion fundraising plan announced on June 1. The plan originally called for a $30 billion underwritten public offering and a $10 billion private placement to an affiliate of Berkshire Hathawax, but an upsized public offering and full exercise of the underwriters' option to buy additional shares brought the actual total raised to $49.6 billion.
The plan also included a $40 billion at-the-market (ATM) offering expected to begin in the third quarter of 2026. No shares were sold under the ATM in April–June, however. And because proceeds from that program are mainly intended to cover taxes tied to employee stock compensation, they cannot be treated as funding for capital spending in this quarter.
Other large companies also raised outside funds, to varying degrees. Comparing equity and debt issuance in April–June, Alphabet raised about $74.4 billion, Meta about $24.9 billion and Amazon about $13.6 billion. Microsoft issued no debt in the quarter, and its equity issuance was limited to employee programs. These are all gross amounts before repayments: for Alphabet, total debt issuance; for Meta and Amazon, proceeds from long-term debt excluding short-term notes. Of Alphabet's debt proceeds, net proceeds from unsecured bond issuance came to $20.3 billion. Amazon, for its part, raised a cumulative $66.998 billion through long-term debt in January–June 2026.
In the outlook Economic Daily News reported, equity raises such as capital increases were cited as a way for heavily indebted AI infrastructure operators to rebuild their finances. Yet among these four companies, the largest equity issuer was Alphabet. Economic Daily News does not claim that large companies never raise equity, of course. Even so, using the mere fact of outside funding as the line between large companies and heavily indebted operators is difficult.
Where the two groups differ more visibly is in funding terms. On August 10, Alphabet completed a $25 billion issuance of U.S. dollar unsecured bonds. Maturities range from 2028 to 2066, and the eight fixed-rate tranches carry rates of 4.500% to 6.500%. Two floating-rate notes are also included.
CoreWeave, by contrast, disclosed on September 18 that its existing unsecured notes carry rates of 8.500% to 9.750%. Alphabet's fixed-rate bonds are at 6.500% or below, while CoreWeave's existing unsecured notes bear interest of 8.5% or more. Because issue dates, maturities and other terms differ, this rate gap cannot be taken directly as a difference in the two companies' creditworthiness. Still, it confirms a wide gap in the interest burden within the same type of funding instrument, unsecured bonds.
CoreWeave also has funding on different terms. The $3.7 billion convertible notes it priced on September 18 carry a 2.875% rate, but because they include a right to convert into shares, they cannot be compared simply with ordinary bonds. A $2.6 billion term loan signed on August 10 carries a floating rate of SOFR, the U.S. short-term benchmark rate, plus 5.50%. Mitsubishi UFJ Financial Group served as joint lead arranger on that loan alongside JPMorgan.
What the April–June numbers show is that two of the four giants spent more on capital investment than their operating cash flow, and that the scale of outside funding does not necessarily track the excess of cash spent on capital investment. Meta raised about $24.9 billion even though its equipment purchases were 94.5% of operating cash flow, while Amazon raised about $13.6 billion at 119.4%. In other words, whether capital spending stays within operating cash flow and whether a company uses outside funding are separate questions.
The difference between large technology companies and heavily indebted AI infrastructure operators therefore appears to lie in terms such as interest rates and maturities rather than in whether they raise outside funds. That gap could shape how much room each company has to invest in 2027, when huge AI infrastructure spending continues. The outlook reported by Economic Daily News, that lending-term gaps will widen by borrower, is consistent with this financial data on that point.
Outside Funding Is Not Proof of a Cash Shortage: What to Check in Upcoming Earnings
Still, it would not be appropriate to treat large companies' outside funding as evidence that their cash positions are tightening. Regarding Alphabet in particular, it is plausible that it is not raising money out of necessity but widening its financial options while it can borrow on favorable terms. At the end of December 2025, before the large fundraising, the company held a combined $126.843 billion in cash and marketable securities. Its trailing-twelve-month FCF through the end of June 2026 was also positive $53.273 billion.
As of June 30, 2026, cash and marketable securities totaled $242.474 billion, well above long-term debt of $98.165 billion. The June-end balance includes funds raised in the quarter, however, so it must be distinguished when judging financial capacity before the raise. JPMorgan's mid-year outlook, as introduced by Fortune, also included an analyst view that high leverage in AI infrastructure financing reflects a strategic decision to borrow while terms are good rather than a shortage of funds. And S&P Global's analysis, reported by fi-desk in May, assessed that both Alphabet and Microsoft have ample financial capacity, backed by their high credit ratings of AA+ and AAA respectively.
Such counterarguments are valid against the interpretation that links large-scale outside funding to a funding shortfall. But this analysis does not claim that Alphabet's finances are strained. What matters is the fact that even companies with ample cash and FCF choose to raise huge sums through stock and bonds. In April–June 2026, at least, Alphabet's equipment purchases exceeded operating cash flow, and large-scale outside fundraising was carried out separately. Although the uses of the two flows do not necessarily correspond directly, it is clear that investment decisions and financing decisions need to be considered separately.
The relationship between large companies' capital spending and operating cash flow is also not fixed. In Meta's July–September 2026 results, announced on October 21, operating cash flow was $32.786 billion while purchases of property and equipment reached $33.942 billion. The ratio was 103.5%, up from 94.5% in April–June to a level above 100%. Equipment purchases that stayed within operating cash flow in the previous quarter exceeded it in the next.
Two checkpoints in upcoming earnings will help judge whether this reading holds up.
The first is Alphabet's July–September 2026 results. If its quarterly report (Form 10-Q) shows FCF turning positive from negative $5.855 billion in April–June, while equity and debt issuance proceeds fall sharply from about $74.4 billion, it would be easier to conclude that the company has returned to covering capital spending with operating cash flow. That would strengthen the interpretation that the large April–June raise was temporary or a strategic securing of funds.
The second is Amazon's earnings, due October 29. The trailing-twelve-month FCF it reported as of April–June was negative $7.604 billion. If that measure returns to positive in the next report, it would indicate improved ability to absorb the cash outflow from expanded capital spending with core business cash flow. However, trailing-twelve-month FCF is a different measure from a single quarter's capital spending ratio, and the two should not be conflated.
If both Alphabet's quarterly FCF and Amazon's trailing-twelve-month FCF improve, the view reported by Economic Daily News, distinguishing large companies with abundant cash flow from heavily indebted operators, would gain persuasiveness. Conversely, if Alphabet's large outside raises continue and Amazon's FCF stays negative, the reading that big companies are also actively using outside funds, and that the difference lies in the terms rather than in whether they raise money, would remain compelling.
In judging the sustainability of AI infrastructure investment, what matters is not simply how much money a company has raised. It must be evaluated by the balance between cash generated by core operations and investment spending, together with terms such as interest rates, maturities and dilution from equity issuance. If capital markets become more selective heading into 2027, what separates each company's competitiveness is likely to be how favorably it can secure the funds needed to keep investing on such a huge scale.
