$MU $WDC $SNDK and $AMAT emerge as key winners in the AI memory buildout

$Bloom Energy Corp(BE)$ spiked from $10 to $300+ in 2 years up 3000%, but its not the real AI bottleneck.

It's actually $Micron Technology(MU)$ $Western Digital(WDC)$ $SanDisk Corp.(SNDK)$ $Roundhill Memory ETF(DRAM)$ .

These will 10x-20x from here:

1/ Bandwidth is the new clock speed.

By 2035, Next-Gen GPUs need 1,024 TB/s of memory bandwidth. That's 64x what $NVIDIA(NVDA)$ $Advanced Micro Devices(AMD)$ $Broadcom(AVGO)$ delivers today. Without HBM scaling, the GPU is just an expensive paperweight.

2/ HBM stacks are multiplying faster than GPU dies.

Rubin (2026): 8 HBM4 stacks. Next-Gen (2035): 32 HBM7 stacks. Memory is growing 4x faster than compute dies. The bottleneck isn't silicon it's stacked DRAM.

3/ Capacity is what makes trillion-parameter models possible.

288 GB on Rubin. 6,144 GB on Next-Gen. That's a 21x jump in HBM capacity in under 10 years. No memory = no frontier AI. Full stop.

4/ Power budgets are being eaten alive by memory.

Total system power goes from 2,200W to 15,360W by 2035. A massive chunk of that is HBM. Whoever solves memory power efficiency wins the datacenter.

5/ The interposer is becoming a city.

Rubin's interposer: 2,194 mm². Next-Gen: 9,245 mm². Advanced packaging is now a critical supply chain choke point.

$MU, $SNDK, $AMAT, $WDC aren't just memory plays they're infrastructure.
