NVDA took a hit today on some interesting news. Rivian just announced they've built their own AI chip for their upcoming vehicle lineup.

This is actually a bigger deal than it sounds. When automakers start rolling their own silicon instead of buying from the usual suspects, it signals a shift in the supply chain dynamics. We've seen Tesla do this, now Rivian's following suit.

The market's reading this as potential lost business for the chipmaker, even though automotive chips are just a slice of their revenue pie. But perception drives price action in the short term.

What's worth noting: this vertical integration trend in the EV space mirrors what we're seeing across tech sectors. Companies want control over their core tech stack, especially when it comes to AI processing power. Can't blame them.
