$AAOI Let's go down a speculative rabbit hole
This is just for fun...
Thompson said substrate supply is basically secured through the end of 2027.
They currently have:
2 suppliers in Europe
2 in Japan
3 in China
(sorry to anyone that thinks there's only 3).
Cool.
But then he said something much more interesting.
AAOI is already talking with 2-3 substrate suppliers about deeper partnerships, potentially even a JOINT VENTURE, because the amount of laser capacity they expect to need in 2028/2029 is going to be insane.
He said their laser capacity could grow by well over 10x over the next few years.
So naturally my brain started going...
What could an AAOI substrate JV actually look like?
My guess is they probably wouldn’t randomly try to learn how to grow InP crystals themselves.
Much more logical would be AAOI + an existing Japanese/European InP substrate supplier
AAOI brings:
> Capital
> Guaranteed huge demand
> Long-term purchase commitments
> Specific wafer requirements
The substrate company brings:
> Crystal growth technology
> Engineers
> Process IP
> Manufacturing experience
And together they build a gigantic new source of InP substrates dedicated partly to AAOI.
That alone would be interesting.
But then I started thinking about the domestic version of this.
Because look at what AAOI is already building.
> They grow their own epitaxy.
> They fabricate their own lasers.
> They are massively expanding transceiver manufacturing.
> They are building out CPO laser capacity.
> And increasingly, they are putting all of this in Texas.
Management even said early feedback from customers around the potential Chinese transceiver restrictions has made customers more aggressive about wanting U.S.-manufactured supply.
They also said the capacity they expect to have through Q2 2027 is basically already spoken for and customers are asking for 20%-40% more than they can supply.
So...
What if AAOI eventually convinces one of its existing foreign substrate suppliers to build a U.S. operation with them?
Then you could theoretically get:
> U.S. InP substrate
> AAOI Texas epitaxy
> AAOI Texas laser fabrication
> AAOI Texas 800G / 1.6T transceiver
> AAOI Texas CPO laser / external light source
That would be pretty great.. right?
And even the raw indium piece could eventually become more domestic.
Commerce already awarded $210M of CHIPS funding to Korea Zinc subsidiary Crucible Metals for a massive Tennessee critical-minerals facility that specifically plans to produce indium in the U.S., with operations expected around 2029.
yes...2029
What years did Thompson literally just say AAOI is planning substrate supply for?
2028 and 2029.
To be clear, this entire domestic JV structure is my speculation.
AAOI only disclosed that it is discussing partnerships with 2-3 substrate suppliers and that a JV is one potential structure.
It could very easily end up being dedicated capacity at an existing Japanese or European facility.
But I think the domestic version is really interesting to think about.
Especially because the U.S. government is already throwing money at domestic InP capacity. Commerce recently signed an LOI for up to $50M for Coherent’s InP expansion in Sherman, Texas.
So now zoom out.
> AAOI wants >10x laser capacity.
> It says substrate supply is secured through 2027.
> It is already planning for 2028/29.
> It is considering JVs with substrate suppliers.
> It is aggressively moving optical manufacturing into Texas.
> Customers are increasingly asking for U.S.-made supply.
> The U.S. government is actively funding domestic InP and indium infrastructure.
And AAOI thinks its CPO lasers are good enough that major customers already want them, with capacity being the limiting factor.
I have zero idea what they ultimately do.
But if AAOI’s endgame is to become one of the most vertically integrated U.S. optical manufacturers, going further upstream into secured domestic InP substrate capacity would make a ton of strategic sense.
NFA.

What I love about GPT-5.6 Sol is how it moves between code, docs, and browser work without losing the thread. It follows repo-specific constraints, verifies risky links before acting, and keeps me in control of actions. That makes it genuinely useful, not just impressive.
