Musk calls Micron's prices reasonable as Micron fell 14% and $150 billion sits locked in

The biggest memory buyer graded his suppliers in public

On October 13 Elon Musk wrote on X↗ that "Micron▼−3.24% — Micron, down 3.24 percent today has been reasonable regarding future memory prices, while others have been extortionate, which is something today's customers won't forget," calling Micron's stance "the smart move for long-term customer loyalty" ¹. Musk buys memory at industrial scale: his xAIPVT$200B — xAI, private, latest valuation $200B runs the Colossus data-center complex near Memphis, and he said on October 2 that Tesla▼−0.86% — Tesla, down 0.86 percent today cut the memory on its AI5 robot chip by a third, to 96GB, because that was "the only way to get enough volume for Optimus production" ¹². He named Samsung, TSMC▲+0.36% — TSMC, up 0.36 percent today and Micron as suppliers to his planned Terafab chip project in April, and left the extortionate ones unnamed ¹.

The tape prices a supply flood; the filings price a lock-in

Micron fell more than 14% over four sessions through October 13, closing down 3.6% on the day, after ChangXin Memory Technologies' president, Cao Kanyu, told a Shanghai conference on October 10↗ that CXMT would ship denser 4F² DDR5 server memory modules by the end of 2026 ¹³⁴. The Philadelphia semiconductor index logged a fifth straight loss, SK Hynix dropped more than 10% in Seoul and Samsung 7.4% ³⁵. What the selling is not pricing: on September 30 Micron disclosed roughly $150 billion of contracted future revenue under 26 long-term agreements↗, every one take-or-pay, covering more than 35% of its revenue through 2030 and backed by $32 billion of customer commitments, mostly cash deposits ⁶⁷. That book exceeds the $133.2 billion Micron sold in all of fiscal 2026, and it is counted at minimum pricing where price frameworks are already set ⁶⁷. Contract prices for DRAM, NAND and high-bandwidth memory had already surged 80–90% in the first quarter of 2026, Counterpoint Research found ¹.

The caveats that decide it

CXMT has yet to show it can build 4F² at commercial yields, its DDR5 cost per bit runs an estimated 30% above the incumbents, and Apple▼−0.13% — Apple, down 0.13 percent today reportedly walked away from CXMT supply talks after finding no price advantage ³. Micron's finance chief, Mark Murphy, says he has "no line of sight" to the shortage easing↗, and JPMorgan expects shortages through 2028 ¹². The post Musk replied to put more than 75% of Micron's fiscal 2027 output as already sold, though that figure is the analyst's relay, not a Micron filing ¹. Watch whether CXMT ships and qualifies server DDR5 by year-end, and whether the suppliers Musk left unnamed start losing orders. In a shortage any maker can name a price; only one is paying for the right to keep its customers when the shortage ends.
