Tesla autonomy dominates as SpaceX merger conviction turns bullish
The author is primarily calling Tesla autonomy, robotaxi deployment and FSD monetization higher, while expecting Tesla to weaken or absorb Uber. No personal holdings are disclosed; late in the window, the author shifted from questioning Tesla-SpaceX merger evidence to treating a combination as increasingly likely, while adding regulatory skepticism around flying-car expectations.

Direction this week
Tesla autonomy conviction remained consistently bullish, centered on robotaxi fleet scaling, FSD monetization and a bearish read on Uber. The Tesla-SpaceX merger stance flipped from evidence-based skepticism on August 11 to increasingly affirmative expectations by August 15-16; flying-car skepticism was newly surfaced late in the window, and Tesla concentration creates clear pump risk.
