AMD ALERT🚨🚨: On Kimi K3 2.8T, AMD has even better profit margins per gigawatt compared to B300, GB200 NVL72, and B200. This is due to AMD's lower TCO and better performance, leading to better profit margins of 53.6% on Mi355X compared to 44.3% on GB200 NVL72. This is from our open-source Agentic Inference benchmark, AgentX. Shoutout to @roaner & @EmadBarsoumPi 10x engineers for optimizing this 2.8T model!
@StockMKTNewz hey @grok make a donut chart out of this positions
$TSLA signs a long-term deal to buy 90% of a 509 MW solar and 360 MW battery project in Arizona. The KKR-backed facility is expected online in 2028 as AI data center growth tightens U.S. power markets.
$AVGO launched its AI XPV platform with $APO and $BX to help deploy more than 20GW of AI compute capacity by 2028. The first $35B tranche will back Anthropic’s 1GW+ AI infrastructure buildout using Broadcom XPUs and networking.
Optical interconnect names are running because $NVDA CEO Jensen Huang basically validated the future AI architecture where copper wins inside the rack but optics becomes unavoidable as AI clusters scale across full data centers. Thats why optical components, transceivers, DSPs, silicon photonics & testing names are getting re-rated today: • $MRVL +30% • $AEHR +21% • $COHR +16% • $LITE +12% • $VIAV +11% • $AAOI +10% • $CRDO -1% (due to earnings)
THE OPTICAL PHOTONICS BOTTLENECK As AI clusters scale past copper’s physical limits, the bottleneck shifts to optical & these are the companies building that layer across the stack: 1. $AAOI building the transceiver layer of the AI network through vertically integrated U.S.-based InP laser manufacturing. It has already secured over $200M in its first volume 1.6T order from one hyperscale customer followed by another $124M in 800G orders from a second. 2. $AEHR building the reliability layer for the optical & AI hardware stack through burn-in & test systems. It just received a record $41M follow-on order from its lead hyperscale customer reinforcing the idea that Sonoma is becoming a key production burn-in platform for high-power AI ASICs. 3. $CRDO building the connectivity layer that helps AI clusters move data faster through active electrical cables, retimers & high-speed interconnect silicon. The DustPhotonics acquisition also extends that platform into silicon photonics before copper becomes a real constraint. 4. $LITE building the laser layer of the AI optical stack through EMLs, optical components & optical switching exposure. The setup is backed by a $2B $NVDA strategic investment & optical circuit switch backlog above $400M with orders reportedly extending through 2028. 5. $VIAV building the testing & validation layer of the optical stack through network instrumentation & photonics measurement tools. It is the picks-and-shovels layer of the transition because every high-speed optical buildout still needs to be tested regardless of which transceiver vendor wins. 6. $COHR building one of the core photonics bottlenecks through indium phosphide lasers, optical engines & communications components tied to next-gen AI networking. It also has a $2B $NVDA strategic investment behind it & is doubling InP device capacity into the 1.6T ramp. 7. $MRVL building the DSP & optical infrastructure layer through electro-optics, PAM DSPs, interconnect silicon & custom networking chips. The Celestial AI deal & NVLink Fusion exposure both strengthen its position as photonics becomes more central to AI cluster design.
$GOOGL TPU shift is now pulling demand across the full AI compute stack from silicon & packaging to optics, power & memory: • CPU Architecture: $ARM • Optical Circuit Switch: $COHR, $LITE, $FN • Memory: $MU, $SNDK, Samsung, SK Hynix • Server Power & Analog: $MPWR, $AEIS, $VICR • Optical & Interconnect: $AAOI, $MRVL, $CRDO • Thermal & Power Management: $VRT, $MOD, $NVT • High-Density Interconnect Cables: $APH, $TEL, $GLW • ASIC Design, Manufacturing & Packaging: $AVGO, $TSM, $AMKR

@NuttyCLD Amazing article! Thank you for making it available!
SpaceX just filed with the FCC to launch up to 1M satellites designed to function as solar-powered orbital data centers creating massive AI compute capacity in space. Elon wants to use Starship’s low launch costs and laser-linked satellites to scale AI compute without stressing Earth’s power grid.
Every new AI generation requires more HBM per GPU which means more revenue per chip for $MU. Just yesterday, $TSLA unveiled Cortex 2, a massive AI compute cluster to train Optimus humanoid robots and power an end-to-end neural network for Cybercab autonomy. The AI economy is becoming memory-first which helps explain why Micron stock is up ~5x over the past year.
3 REASONS $MU IS HAVING ITS $NVDA MOMENT 1. HBM demand growing faster than GPU demand 2. Memory content per GPU increasing every generation 3. Edge, autonomy and agents all memory-intensive Memory is becoming critical infrastructure in the new digital economy as scaling laws
@GustavoBolsa Socialismo y moneda fiat son lo mismo
Tesla’s chip game is no joke. AI5 chip will be roughly comparable to a Nvidia Hopper Chip in a single SoC, and Blackwell class when you run two of them together. Those AI chips from Nvidia run ~$25K-$50K each. AI5 will run at ~250W compared to H100’s 700W or Blackwell’s 1,000W+ in full spec. Tesla is LOCKED IN.
