TL;DR: Most of the numbers Burry used match Microsoft's annual report. But the move to 25-year useful lives, the shift toward operating leases, and the capex outlook of roughly $175 billion were all stated by the CFO on the July 29 earnings call. The bigger story is scale: $329.1 billion of leases not yet commenced, about 3.7 times the lease liabilities already on the balance sheet.

On Microsoft's fiscal 2026 fourth-quarter earnings call on July 29, 2026, CFO Amy Hood said in her prepared remarks that the company was extending the useful lives of its data centers and office buildings from 15 to 25 years, that more of its future data center leases would shift from finance leases to operating leases as a result, and that this brought its calendar 2026 capex expectation to roughly $175 billion with investment plans unchanged. When Michael Burry wrote on Substack on September 24 that Microsoft was making its spending look smaller, most of his numbers matched Microsoft's annual report, but nothing had been uncovered: the company had announced the change, and the reason for it, two months earlier. What deserves attention is the scale: $329.1 billion of leases not yet commenced, roughly 3.7 times the lease liabilities already on the books.

## July 29: the CFO said it in her script

Microsoft reported its fiscal 2026 fourth quarter that day. After walking through the quarter and just before the outlook, Amy Hood added a paragraph. Starting with fiscal 2027, the estimated useful lives of data centers and office buildings would go from 15 to 25 years, based on the company's operating history and how long it expects to use these assets.

She was plain about what it would and wouldn't do. The change only affects the timing of future depreciation, she said, with a "minimal benefit" to fiscal 2027 operating income. The bigger effect is on capital expenditures, because "more of our future datacenter leases will shift from finance leases to operating leases," and "finance leases are included in capital expenditures while operating leases are not." Then the number: setting this aside, calendar 2026 investment expectations were unchanged, but the lease shift brought the expectation to about $175 billion.

Three months earlier, on the April 29 call, her calendar 2026 figure had been roughly $190 billion. I covered the cut itself in my [notes on MacroMicro EP209](/en/blog/macromicro-ep209-the-half-eaten-peach/), so I won't repeat it here. In that post I described it as depreciation being spread over more years. Rereading the CFO's words, she says the depreciation effect is small; capex shrinks mainly because leases move into a different bucket. Nothing on this site has explained that bucket yet, so I'll spend some time on it.

Wire coverage of the earnings that week already carried both the 15-to-25 change and the $175 billion figure.

## The line nobody lingered on: two kinds of lease

Microsoft builds some of its data centers and leases others from developers. The leased ones have to be classified first.

A finance lease is closer to buying something in installments. An operating lease is closer to plain renting. US lease accounting lists five tests, and a lease that meets any one of them on the day it starts is a finance lease: ownership transfers at the end; there's a purchase option the tenant is reasonably certain to use; the term covers the major part of the asset's remaining economic life (75% in practice); the present value of the payments equals substantially all of the asset's fair value (90% in practice); or the asset is so specialized the landlord has no other use for it afterward. Only when all five fail is it an operating lease. The classification is set on the start date.

Which bucket a lease lands in shows up in three places.

The first is capex, the bucket Hood's line was about. Microsoft reported roughly $41 billion of capex for its fiscal 2026 fourth quarter, which lines up with $35.8 billion of cash paid for property and equipment plus $5.6 billion of finance leases (those two add to $41.4 billion, a small gap from the reported figure).

The second is the income statement. A finance lease's cost is split into amortization of the asset and interest, and the interest sits below operating income. An operating lease shows a single lease cost inside operating expenses. In fiscal 2026 Microsoft booked $5.4 billion of finance lease amortization and $2.5 billion of interest, against $7.0 billion of operating lease cost.

The third is the cash flow statement. Operating lease payments come out of operating cash flow, $6.4 billion in fiscal 2026. Finance lease principal goes through financing activities, $3.1 billion that year.

One thing is the same in both buckets: they're on the balance sheet. The accounting policy note says so directly, with operating leases carried as right-of-use assets and lease liabilities. So "switch to operating leases and the debt disappears" is a misunderstanding. What changes is that the lease skips the capex line and the rent leaves through operating cash flow instead.

The direction is easy to flip, too. I heard an English-language tech podcast in early August describe it as operating leases being turned into finance leases. People who follow this industry every day mix it up. Hood's own words put the direction the other way: finance to operating.

Why would useful life affect classification at all? Because the 75% test compares the lease term with how long the asset can be used. Stretch the asset's life and the same lease covers a smaller share of it, so it's less likely to clear the bar.

![Two horizontal bars compare a 13-year lease term with the asset life: with a 15-year asset life, 13 years exceeds the 75% threshold, while with a 25-year asset life, the same 13 years falls short of it.](/figures/lease-13y-vs-75pct-threshold-en.svg)

## September 24: the same facts, a different story

This isn't the first time Burry has gone after big-tech accounting. In November 2025 his target was server depreciation schedules. The Taiwanese podcast 科技浪 (Tech Wave) spent its November 17, 2025 episode on it, and the figure discussed there, about $176 billion of depreciation understated across 2026 to 2028, was his own estimate, not a figure from any filing. On November 20, the Taiwanese podcast 財報狗 (Caibaogou) noted that NVIDIA's CFO had pushed back on an earnings call. That round was about machines. This one is about buildings and leases.

On September 24, 2026, Burry published a long Substack post, "Capital Cycle IQ & Forensic Files on the Big 5 Hyperscalers," going through the five big cloud builders one by one. The free opening talks about roughly $3 trillion in combined purchase commitments, future leases and other off-balance-sheet arrangements across the five. The Microsoft lease section sits behind the paywall.

An English-language markets story the next day summarized it. Burry, it reported, said Microsoft had nearly tripled its uncommenced leases to more than $300 billion while stretching the upper end of its data center useful-life range from 15 to 25 years, shifting spending toward operating leases and lowering reported capex for 2026 and 2027. The only words that story put in quotation marks and attributed to him were "Too cute by half."

Two more lines travelled widely in the Chinese-language version: that "no analyst has ever asked about this," and that Microsoft uses these numbers "as a lever to get the outcome it wants." The original is behind the paywall and I couldn't find either line anywhere public, so I'm not treating them as Burry's words.

## Early October: a Chinese-language news flash

By the time it reached me, the story had been boiled down into a short Chinese-language flash with six bullet points. It read like a list of things someone had been caught doing.

I came across it on October 8, 2026. Read in the flash's tone, it's easy to come away thinking Microsoft had been exposed: a quiet change in accounting, capex made to look better. Go back to the July 29 call transcript and it turns out the whole thing is in the CFO's own prepared remarks, including the line explaining that finance leases count as capex and operating leases don't.

The numbers weren't the problem. The "exposed" part was.

![A timeline has four markers: late April and late July are far apart, the intervals from late July to late September and then to early October narrow sharply, and a bracket groups the three points on the right as the same event.](/figures/timeline-disclosure-to-newsflash-en.svg)

## Checking the six claims

I checked each one against Microsoft's fiscal 2026 annual report (filed July 29, 2026), the two earnings calls, and the US lease accounting standard.

| What the flash said | Verdict | The condition it left out |
|---|---|---|
| Data center leases average about 13 years | Partly right | 13 years is the weighted-average remaining term of finance leases. Operating leases are at 6 years. The report doesn't break out data centers separately |
| A lease covering most (75%) of the asset's economic life is a finance lease; otherwise it's operating | Partly right | 75% is one of five tests. Another is whether the present value of payments reaches 90% of the asset's fair value. A lease is operating only if all five fail |
| The old useful life was 15 years | Right | The report says buildings and improvements are depreciated over "five to 15 years," so 15 is the top of a range |
| Now it's 25, so 13 years is only about half and the leases become operating | Partly right | Only "more of" the future leases shift; existing leases aren't reclassified. And 25 years appears only on the call so far. The annual report still says five to 15 |
| The 2026 capex forecast fell to about $175 billion while actual plans stayed the same | Right | That's calendar 2026, not fiscal 2026 |
| Uncommenced leases of $329.1 billion, up 3.5 times in a year | Right | From $92.7 billion a year earlier, so 3.55 times. This year's report also adds that some arrangements depend on contractual conditions being met |

A few of those conditions deserve more room. Thirteen divided by 15 is about 87%; divided by 25 it's about 52%, so "about half" is correct arithmetic. But 13 years is how much time is left, on average, on the finance leases Microsoft already has. It says nothing about how long the new ones will run. The report puts the terms of the uncommenced leases at 1 to 20 years. Seventy-five percent of 25 years is 18.75, so a 19- or 20-year lease could still be a finance lease under that test, and the present-value test can make it one on its own. Hood said "more of," not "all." That word choice was precise.

![The upper lease bar is divided into an elapsed segment and a remaining 13-year segment, while the lower bar shows new lease terms from 1 to 20 years, with its right end extending beyond the 18.75-year threshold.](/figures/remaining-term-vs-new-lease-term-en.svg)

As for 25 years, the change takes effect in fiscal 2027, and the annual report covers the year that ended June 30, 2026, so it isn't in there. As of October 8, the first-quarter 10-Q hadn't been filed yet.

## The real story is scale, not classification

After going through all six, the classification question struck me as the small one.

As of June 30, 2026, the report says, Microsoft had $329.1 billion of leases, mostly data centers, that had not yet commenced. They start between fiscal 2027 and fiscal 2033. The lease liabilities already on the balance sheet come to about $88.5 billion: $21.9 billion operating plus $66.6 billion finance. So the leases still waiting to start are about 3.7 times the ones already recorded. That ratio is my calculation.

![Three columns use the same scale: last year's uncommenced leases are short, this year's are three and a half times taller, and existing lease liabilities on the balance sheet are only about as tall as last year's uncommenced leases.](/figures/unstarted-lease-scale-vs-balance-sheet-en.svg)

Once those leases commence, they land on the balance sheet whichever bucket they fall into. The operating bucket just makes the capex line look a bit smaller and takes a little more rent out of operating cash flow each year.

So I think Burry is about half right on what matters. Microsoft is locking in a huge amount of future data center capacity through leases. That figure is now 3.55 times what it was a year ago, and part of it is conditional. But you can make that case with the $329.1 billion line from the annual report. You don't need to frame it as a company getting caught.

## How long are the other rulers?

Is Microsoft's 25 years unusually long? Here are building lives from each company's latest annual report:

| Company | Fiscal year end | Building / data center useful life | Leases not yet commenced |
|---|---|---|---|
| Microsoft | 2026-06-30 | 5 to 15 years; call says data centers move to 25 from fiscal 2027 | $329.1B |
| Alphabet | 2025-12-31 | 7 to 40 years | about $58.5B |
| Amazon | 2025-12-31 | up to 40 years (or the building's remaining life, if shorter) | about $96.4B |
| Meta | 2025-12-31 | 25 to 30 years | about $103.8B |
| Oracle | 2026-05-31 | 1 to 40 years | about $260B |

Two caveats. The dates differ: Microsoft and Oracle are mid-2026, the other three are year-end 2025. And each company describes uncommenced leases a little differently, some as total payments and some as commitments, so this isn't a same-day, same-basis comparison.

The table cuts both ways. If you think Microsoft is being conservative, you'll point out that 25 years only reaches the bottom of Meta's range and stays well short of the 40-year ceilings at Alphabet, Amazon and Oracle. If you think it's moving numbers around, you'll point out that it lengthened lives in the very year its lease pipeline exploded. My own read: the length itself isn't unreasonable, but the timing is worth remembering.

## Further thoughts: is this a leak or a rerun?

When a flash like this scrolls past, what most people want to know is one thing. Is this new bad news, and should I worry about what I own?

What I took from this one is to split it into two layers. The first is the facts: are the numbers right, and which document are they from. The second is the story: was this dug up, or did the company say it out loud. Flashes often get the first layer right and the second wrong, and the second is usually the part that makes people nervous.

![An arrow representing a news alert passes through the first gate labeled “Facts” but is stopped at the second gate labeled “Story.”](/figures/two-gates-fact-and-story-en.svg)

Telling the two apart isn't hard. Pick the single most important number in the flash, here the $175 billion, and look for it in the company's latest earnings call or annual report. If the CFO said it in her prepared remarks and explained why, it's a disclosed change in accounting, and the market has known since July 29. The real question becomes whether you agree with the approach, not whether you were fooled.

If you want to see whether this drifts somewhere worse, there's one concrete line to watch. The annual report lists "right-of-use assets obtained in exchange for lease obligations." For fiscal 2026 it was $4.6 billion for operating leases and $24.6 billion for finance leases, against $7.8 billion and $20.5 billion the year before. When the fiscal 2027 first-quarter 10-Q comes out, if the shift Hood described is real, the operating share of that line should rise noticeably. Checking it will tell you how much "more of" turned out to be.

## One thing to take with you

What this one taught me: when a story says someone "got caught," first check whether they said it themselves.

What I do now: next time I'm about to forward a "so-and-so exposed" flash, I first open the most recent public record from whoever it's about. For a company that's the earnings call; for a person it's their own post. I find the key number or sentence from the flash and write down one line: did they say it themselves, and on what date.
