Micron up 44.76% in seven days. Meta down 2.01%. The capex flowed where the suppliers sit.
Two weeks ago Micron sat at $453. Friday it closed $757.35. Sandisk went $911 to $1,562. Western Digital ran $387 to $481.
Over the same fourteen days Meta lost 9.35%. Microsoft 2.49%. Amazon held flat.
The names that BUY chips are softening. The names that SELL chips are vertical.
Q1 2026 hyperscaler capex landed at $140.3 billion across Microsoft, Amazon, Alphabet, and Meta. Up 89% year over year. AWS alone printed $41.5 billion in three months.
The order book is real. The chips are physical. They contain DRAM and NAND made by Micron, Sandisk, SK Hynix, Samsung. They contain HBM stacks. They sit in racks built by Western Digital and Seagate.
The hyperscalers funded the build through balance sheets that already show the strain. Meta's 10-Q discloses $182.88 billion of leases not yet commenced, against $58.7B of recognized long-term debt. Oracle's last 10-Q shows $261B of additional lease commitments and $552.6B of remaining performance obligations, against $124.7B of notes payable.
The buyers committed the spend before the chips ship. The suppliers cash the check on delivery. The equity expression is now following the cash, not the announcement.
Meta's leases-not-commenced grew from $52.56B in June to $182.88B by Q1 close. Tripled in nine months. The market reads that as either capex efficiency turning the corner, or a wall of fixed cost arriving in 2027 and 2028.
Microsoft and Alphabet face the same arithmetic at different scale. Microsoft RPO sits in the $300B range. Alphabet capex up 108% Q1.
The buyers are spending against fixed margin. The suppliers are pricing into a shortage they cannot fix. NAND industry capex for 2026 is $22.2 billion total, less than what Amazon spent in three months building data centers.
HY OAS closed Friday at 279bp, a 30-day low. IG OAS at 79bp. AAA OAS quietly widened +3bp over thirty days to 38bp.
HY tightening with AAA widening is unusual. The AAA-rated layer holds data-center-backed asset-backed securities priced at 150-200bps over the broader index. As the off-balance-sheet stack accumulates, the structured-product layer is the first to mark.
The widening is small. It is also the only spread moving the wrong way through the entire risk-on tape this week.
The cohort did not peak May 3-4 as the synchronized highs suggested. Micron took out a fresh peak Friday. Sandisk closed above its prior high.
The bubble narrative requires a synchronized top followed by a synchronized rollover. This is the opposite. The trade rotated. The capex is real, the chips are real, the suppliers' order books are full, and the funders are holding the bag.
For dry powder the question is which side of the rotation is durable. The suppliers' multiples are running into NAND industry capex constraints that cannot expand fast (Kioxia-Sandisk JV through 2034, no new fabs announced, $4.5B JV share against $22B industry total). The hyperscalers' equity is compressing into a 2027-2028 wall of lease commitments.
