I think the market has this wrong, especially if they think this is in anyway tied to the company gaining some new foundry customer.
This appears to me to be a typical financial leveraging exercise, where they take on a lot of debt in order to own 100% of the revenue from lagging node production.
Seems like typical short-term Finance thinking to me, all well and good unless demand falls off a cliff when the megacap tech hyperscalers are forced to pull back sharply on capex.
Why would they do that? Because (unlike the AI disruption they all face) the other corporate users of AI are not ready to run off an adoption cliff.
Each and every one of the megacap tech companies are in an existential race, scrambling to replace a good deal of their existing products with datacenter revenues. Users are already shifting to use of AI in place of the key products offered by the megacap tech companies, so those companies are moving to AI as quickly as possible, before their entire business model is destroyed.
Oracle is a great example of what is happening, where they are slashing headcount at the same time as they are going all in on debt-fueled datacenter construction. Amazon appears to be at the other end of the spectrum and that is likely because they don't feel as at risk from AI. Microsoft, Google, Meta..soon to be disrupted.
So much manipulation by so many to create competitive moats, all for naught.
Other companies are also adopting, but not at such a furious pace, and so don't need the datacenter growth being offered by the megacap tech companies. At some point (very soon) there will be a reckoning, which results in datacenter capex being probably cut in half (more or less).
AI is still a thing, just not quite as fast as megacap tech companies need it to be.
