[DigiTimes]: China approves first exports of Indium Phosphide (InP) substrate in 2026 which should help alleviate bottlenecks in the optical communications market. Very bullish development for $AXTI digitimes.com.tw/tech/dt/n/shwn…



$AXTI shares are down ~30% after a below-expectations pre-announcement of earnings, but the prior earnings do not change the thesis around InP shortages. I have initiated a position. AXT is one of the few pure-play suppliers of indium phosphide (InP) substrates, a critical material for high-speed optical communications, silicon photonics, and AI datacenter interconnects, and InP supply constraints are emerging as a structural bottleneck in the AI build-out. If demand for InP remains tight and the company’s role in easing that bottleneck stays intact, the fundamental thesis remains unchanged. For investors with a long horizon and conviction in optical/AI infrastructure demand, this sell-off may present an entry point. cc: @aleabitoreddit




This really is making me wonder. What happened is retail based on @aleabitoreddit and some other frontier analysts front ran the optics/photonics cycle. Then we started seeing statements that $JPM Fidelity etc have been buying $SIVE Now we start hearing a narrative saying "you know what? You're WAY too early with that stuff. You should sell it." So they want us to sell it right as they're accumulating it 🤔










On top: $NVDA CEO also called out Silicon Photonics (optical networking) with memory. Stating that Nvidia would require “supply volumes beyond imagination”. What a bullish read through on the SiPH supply chain from $SIVE (now upstream Nvidia ecosystem) to $SOI
