Quick Read – Musk identified memory as his AI compute ceiling rather than power or GPUs, spotlighting Micron (MU) as the sole U.S.-based HBM maker among just three global suppliers. – On SpaceX’s (SPCX) earnings call, Musk said memory demand grows 200% annually against 20%…
pply growth, predicting prices will keep rising, not falling. – TrendForce projects Q3 2026 DRAM price growth decelerating to 13% to 18%, raising risk that Micron’s low-looking valuation multiples could prove misleading. – On SpaceX (NASDAQ:SPCX)’s Q2 2026 earnings call held Aug. 4, 2026, Elon Musk answered a question about the pace of compute buildout with five words that memory investors have circulated ever since: “Limiting factor currently is memory.” The remark lands directly on Micron Technology (NASDAQ:MU), the only U.S.-based maker of high-bandwidth memory and one of just three global HBM suppliers. SpaceX itself trades publicly as NASDAQ:SPCX after its 2026 IPO
Musk just told public shareholders that memory caps his AI ambitions, above both power and GPUs. What Musk Actually Said Musk framed the constraint in his own supply-versus-demand math. “The memory output is increasing by around 20% per year. Now, normally that would be fantastically fast and amazing for any large, mature industry.
But ask yourself, is the demand increasing by 20% a year? No, the demand is increasing by 200% a year, maybe higher. So if you’ve got demand increasing much faster than supply, then Economics 101 would suggest that the price increases.
