Micron Technology Inc. (MU) is set to report its fiscal fourth-quarter results after the bell on Sept. 30, and the print could test whether the market finally rethinks a long-held assumption: that the memory-chip maker is merely a cyclical stock.
For years, Micron has been priced as a classic memory-cycle name. Demand swings, and manufacturers that add capacity during tight periods have, in the past, sown the seeds of oversupply further down the road. But the current upcycle, driven by the build-out of artificial-intelligence infrastructure, is unlike anything the industry has seen before—and its profit surge has investors asking whether Micron’s market value can overtake Tesla Inc. (TSLA).
Nvidia Corp. (NVDA) estimates that the five largest AI hyperscalers will spend nearly $800 billion on data centers this year, a figure it projects will rise to $1.3 trillion in 2027. By 2030, Nvidia sees global data-center capital expenditure reaching between $3 trillion and $4 trillion.
The processors powering that build-out require extraordinary amounts of memory, particularly high-bandwidth memory (HBM), where supply remains nowhere close to demand.
“We expect tight conditions to persist beyond calendar 2027 as a result of AI-driven demand across all segments coupled with structural supply constraints,” Micron Chief Executive Sanjay Mehrotra said on the company’s June earnings call.
Management also expects at least half of Micron’s revenue to eventually come under multi-year take-or-pay contracts, with the largest agreements carrying floor prices through their terms.
The contrast with Tesla is already stark.
Micron earned $28.2 billion in GAAP net income in its fiscal third quarter ended May 28—more than double the $13.8 billion it posted the prior quarter and roughly 15 times the $1.9 billion it earned a year earlier. For the first nine months of fiscal 2026, net income was about $47.3 billion, nearly nine times the prior-year period.
Tesla, by comparison, earned a combined $25.9 billion in GAAP net income across all of 2023, 2024 and 2025 combined. Strip out a roughly $5.9 billion one-time non-cash tax benefit Tesla booked in 2023, and that three-year total falls to about $20 billion.
Tesla’s earnings have been shrinking since 2023: net income fell to $7.1 billion in 2024 and $3.8 billion in 2025. In its second quarter, net income was $1.1 billion, down 5% year over year, and operating margin contracted to just 1.4% from 4.1% a year earlier. Over the last four reported quarters, Tesla earned roughly $3.8 billion—about one-thirteenth of what Micron earned over the same span.
Micron currently trades at a market value of about $1.22 trillion, versus roughly $1.47 trillion for Tesla. Yet the valuation multiples diverge sharply. Micron’s shares are priced at just 6.8 to 7 times projected fiscal 2027 earnings, while Tesla trades at roughly 165 times its estimated adjusted earnings per share for 2027. Management has guided to fourth-quarter GAAP earnings of $30.73 a diluted share, plus or minus $1.00—implying another sequential profit increase.
For Micron’s market value to surpass Tesla’s at Tesla’s current level, Micron shares would need to reach roughly $1,300, just above its 52-week high of $1,255, and still only about 8 times fiscal 2027 earnings. Alternatively, Tesla shares would need to fall to around $309—a level it traded below as recently as late July.
The Sept. 30 print will be the first real test of that re-rating thesis. Memory stocks can swing violently in both directions, and a steep downturn in memory prices would likely cut the call short—but for now, the numbers already point to a widening gap between what these two giants are earning and what the market is paying for them.
