Michael Burry flags $3 trillion AI write-off risk at Microsoft, Amazon, Oracle

Burry's concern is not that the AI spending is happening, but that it may be getting ahead of the demand that is supposed to pay for it. He pointed to net capital investment by S&P 500 companies reaching 2.07% of GDP at June 30, a level he described as the highest in nearly four decades outside the period following the 2000 Nasdaq peak. That is the backdrop for the roughly $3 trillion in commitments and other exposures he attributes to Microsoft, Amazon, Alphabet, Meta and Oracle.

The comparison he draws is to the late-1990s telecom buildout, when heavy investment was followed by excess capacity, weaker returns and substantial depreciation. He expects the current investment to keep rising, and said write-downs could emerge around 2028 or 2029 if AI capacity exceeds demand. He also raised questions about Oracle's treatment of customer prepayments and cited rising financing concerns surrounding its large data-center projects.

The stakes appear to hinge on the pace of AI demand relative to new capacity, and on how these commitments are ultimately valued. If demand keeps up, the spending remains a growth story; if it lags, the same obligations could become the kind of asset write-down Burry is flagging, a risk that may weigh most on the finance and investor-relations teams at the five companies named.
