What stands out

Elon Musk used SpaceX's earnings call to announce an exclusive engineering relationship with Nvidia, a short sentence that matters because SpaceX is the kind of customer that stretches compute hardware to its limits. For Nvidia, this is a branding and demand signal that dovetails with already extraordinary growth; the company has been compounding revenue and profits at a pace most incumbents can only admire. For Tesla, it is a reminder that Musk runs several tech experiments at once, and choices at SpaceX can influence supply chains and bargaining leverage across his companies.
