Warning: The entire AI industry will likely be bottlenecked by two companies: 1. $AXTI ($700M) 2. $SMTOY ($31.7B) Which both control 60–70%+ of the world's InP substrates. Future $NVDA, $GOOGL TPU v7 pods, $META, $MSFT, $AMZN hyperscaler clusters require InP-based lasers and receivers. $AVGO, $LITE, $COHR use for EMLs for 800G/1.6T transceivers, DFB lasers, and other optical infra. Without InP substrates, the supply chain falters. After looking at TPU BOM to Maia BOM, it looks like future ASICs + GPUs + hyperscaler deployments are heavily reliant on photonics. And two vendors could freeze the global InP substrate market covering nearly all of: - Hyperscaler optics (TPU pods, etc) - Optical transceivers (5g, data) - LiDAR (robotaxis, drones, military) -Optical Modules (interconnect clusters) - Silicon photonics laser dies (Nvidia’s future co-packaged optics and Intel/Broadcom SiPh engines use InP CW laser arrays.) Since these companies make up majority of the market supply: -AXTI (est. ~30–35%) -Sumitomo (est.~30%) - JX Nippon (est. 10-15%) That’s it. (eg. 2021 industry note from Yole states that "Sumitomo Electric + AXT together had “more than 75%” of the InP substrate market") Hyperscalers/AI are moving toward photonics but the entire AI industry is fragile. If either $AXTI or $SMTOY stop supplying materials, the entire future AI buidlout gets crippled. It's even crazier that a $700m company could become the the center of it all. InP substrate will likely one of the biggest bottlenecks alongside HMB as the AI industry shifts to photonics.



Changed my mind about Soitec ( $SLOIF ) and took a sizable position ~43 for CPO exposure. $NVDA GTC next week biggest catalyst pushing photonics and this architecture. ~1.5B euros MC. Trading at 1x book value and ~2x P/S (very depressed valuations) Genuine monopoly over substrates side for CPO (typically very premium valuations for photonics + even extra premium for monopoly status) Algos and analysts might get confused over market share but it’s an actual monopoly over SOI substrates since they give licenses to other players like Shin Etsu for diversification sake eg. $TSM doesn’t like just 1. I don’t think institutions will wait until next year to frontrun these names like Soitec or $TSEM (and most probably haven’t even heard of these names like $AXTI yet) This timing would be buying the likely bottom of the depressed smartphone cycle, while getting full upside of CPO mid-late 2027 + $NVDA GTC catalyst next week. I personally think it’s a 3x from here so I went long.




Wow One of the best days of the year for new highs - $RSP near highs and growth stocks destructed My screens are again full of stuff; just not the stuff I usually am in. ROTATION baby. Rarely see this.



$HIMS weekly Not sure if this is why shorts are doubling down but 200 weekly moving average is a good target for algos, this is also where the previous all-time high is







$QQQ Nasdaq. Are we about to break the structure and challenge ATH $637? All up to $MSFT $TSLA $META $NOW $IBM $LRCX $CLS earnings tomorrow. Also Fed Interest decision.


$IREN Update Seasonal strength very strong over the next 2 weeks: Average return: 49% Worst return: 18% Earnings on Thursday
