📋 Capture InP supply shock and photonics BOM value through key players in AI supply chain
Capture InP supply shock and photonics BOM value through key players in AI supply chain.
Evidence & details
- +AXTI is vertically integrated and one of the most important suppliers in the AI photonics supply chain.
- +The AI buildout is extremely reliant on AXTI for raw materials (inp substrates) to ramp photonics.
- −High risk is priced in, reflected in low valuation.
- −Any disruption in AXTI's supply could impact the already fragile AI supply chain.

@thgstar2 $SMTOY as a stock would likely be fine since it's an extremely large Japanese giant and InP substrate production is just a small part of their business. But China sent a nuke over to the InP supply chain in Japan with the export control today. https://t.co/Cq2wssDTA3
Thesis: Sumitomo Electric (SMTOY) likely unaffected by China's export ban on dual-use items to Japan because InP substrate production is a small part of its business.
@SwanShapedBird There is a lot risk with $AXTI for sure. That’s why it’s valued like a penny stock at $700m and not $30B+ like $SMTOY despite being both vertically integrated and one of the most important suppliers. And when you combine with the fact the AI supply chain is extre…
Thesis: AXTI is a vertically integrated key supplier of indium phosphide substrates critical for photonics in AI infrastructure, yet valued at only $700M due to perceived risks.
@VulcanMK5 Yep, $LITE and $COHR are amazing and are up quite a bit since they tons pricing power. Go few levels deeper into $AXTI (vertically integrated), Sumitomo -> Dowa, etc. the concentration risk + bottleneck flashes warning signs. With HBM, it was an investment opport…
Thesis: Photonic supply chain bottleneck similar to HBM presents investment opportunity in vertically integrated small caps AXTI and SMTOY as hyperscalers hoard materials.
AXTI and SMTOY control 60-70%+ of the InP substrate market, which is critical for AI photonics components like lasers and receivers used in hyperscaler clusters. Without these substrates, the AI supply chain falters, making these companies potential bottlenecks as the industry shifts to photonics.
source ↗Potential InP substrate bottleneck when hyperscaler ASICs ramp up in mid-2026, benefiting AXTI and SMTOY as dominant suppliers.
source ↗AXTI and SMTOY control over 60% of global InP supply, creating a critical bottleneck for AI data center optical interconnects as the industry shifts from copper to photonics.
source ↗AXTI and SMTOY control over 60% of critical InP substrate supply for AI photonics, making them a bottleneck and single point of failure for the AI buildout. Their obscure status and small market caps contrast with their strategic importance, likely leading to supply hoarding and multi-year agreements.
source ↗InP substrate industry is bottlenecked by AXTI and SMTOY, controlling 60%+ of critical global supply, demand far exceeds supply for AI transceivers/lasers, making them essential chokepoints for AI scaling.
source ↗InP substrate supply is a critical bottleneck for AI photonics, with a duopoly of $AXTI and $SMTOY controlling majority supply. Hyperscalers' AI programs (TPU v7, Maia, MTIA) are tethered to these companies, leading to price spikes and potential delays.

source ↗Indium Phosphide is a critical bottleneck for AI optical interconnects, controlled by a duopoly ($AXTI/$SMTOY) with $AXTI also dominating feedstock supply. As AI clusters scale and shift to optical interconnects, InP demand will surge, benefiting these companies.
