Never really looked into neoclouds and it might just be me, but the neocloud business looks unattractive...

The biggest supporting argument I hear for them are how high compute prices are, but does this seem dependable for this business?

On the other hand, they are:

> Capital intensive

> Riddled with debt

> Very competitive

> Low margin

If there is someone the equivalent of Nvidia in this business, its is Nebius $Nebius(NBIS.US)

Outside of that, everything looks to be low quality.

What are the barriers to entry in this business? It seems anyone can open up as a GPU vendor to hyperscalers tomorrow, and be successful. Why? Because Nvidia has GPUs to sell. Do more neoclouds hurt them? Absolutely not.

Would love to hear the counter to this. Just an informative debate. I've never done something like this, so maybe it can be useful.

Intel secures another major order for advanced packaging; SK Hynix's next-generation HBM will incorporate EMIB technology.

"South Korean memory giant SK Hynix announcing that it will incorporate Intel's EMIB advanced packaging technology into its next-generation high-bandwidth memory (HBM)."

"Industry analysts believe that when Intel previously introduced its EMIB 2.5D solution, it mentioned that the EMIB-T version incorporates TSV technology to enhance vertical power supply and support design conversion from other packaging technologies. This aligns perfectly with SK Hynix's direction of releasing HBM4 towards doubling the number of I/Os and adding TSV technologies, which is likely one of the reasons why SK Hynix adopted Intel's advanced EMIB packaging."

We need more FAUs for CPO.

"Based on the estimated shipment of approximately 20,000 Spectrum-X units this year, the optical engines required would need 600,000 to 700,000 FAUs (Fiber Optic Active Units), and this number is expected to reach millions by 2027."

"Currently, the supply chain capacity cannot meet this demand."

Zhongji Innolight's Interim Report covering optics:

> Silicon photonics penetration in the global datacom optical interconnect market is expected to rise further, from about 38% in 2025 to about 73% in 2030.

> Optical interconnects accounted for about 5% of global AI capex in 2025, and are expected to reach about 10% over the long term. The global datacom optical interconnect market is projected to grow from $19.4 billion in 2025 to $98.6 billion in 2030, a compound annual growth rate of 33.8% from 2026 to 2030.

J.P. Morgan: DRAM & NAND bit demand vs bit supply

DRAM bit supply/demand to be worse in 2027 before balancing in 2028, same for NAND.

Note: this is for bits. Does not mean shortage is solved in 2028.

Impressive...but at the same time hard to believe that by 2029, the market share for GPUs will be ~21% compared to ~79% for ASICs. Also implying a 17.5% market share for Nvidia lol.

I don't buy that a single bit.

J.P. Morgan on memory LTAs: "A relatively misunderstood element within LTA is the resilience of pricing. Majority of the LTA discussion is currently centered around server memory. CSP and AI related memory demand is likely to be the majority (over 70% of total bit demand and 85+% of total revenue) of the contract. Server memory solutions carry a significant price premium over non-server applications and we believe the LTA mix increase will be pricing/margin accretive from a mid-to-long term horizon."

Memory Stanley: Memory

> Nature of Inflation: Shifted from viewing memory inflation as cyclical to recognizing it as structural.

> Demand Dynamics: Moved from the belief that higher prices cannibalize demand to realizing that higher prices and supply scarcity are actually accelerating demand.

> OEM Pricing Power: Changed from assuming OEMs absorb higher costs to seeing that OEMs are successfully passing through pricing and margin stacking.

> Supply Outlook: Replaced the expectation that supply would eventually catch up with the outlook that supply will remain constrained for years.

> Market Drivers: Expanded from a simple refresh cycle view to a combination of refresh, capacity expansion, and pull-forward demand.

> Overall Market Impact: Shifted from viewing memory inflation as universally bearish for hardware to understanding that memory inflation creates winners and losers.
