Tesla shares have been losing ground for over a month now, with the retreat largely a function of Elon Musk's growing political role and Tesla's slowing sales momentum, particularly in the EU. While some sales stagnation was expected as Tesla retires the older Model Y in favor of its latest iteration, dubbed Juniper, the sheer loss of sales momentum that we've witnessed in recent weeks have prompted some analysts to blame the politicization and the attendant deterioration in the EV giant's brand image. Yet, Tesla continues to bravely soldier on.

To wit, MoneyUDN is now reporting that Tesla has tapped TSMC to manufacture its latest FSD chips on the 3nm - 4nm process, while Samsung will continue to produce the older iterations of the autonomous mobility-enabling chip.

Of course, Tesla's Dojo supercomputer, which trains the EV giant's neural net, already leverages chips built on TSMC's 7nm process.

This report comes as Tesla is now rolling out a software update in China, enabling enhanced driver assistance on city roads, automatic lane changes, traffic sign recognition, and an updated package of local maps. These features, however, require HW4 cars and an upgrade to the Autopilot subscription package.

Meanwhile, Tesla continues to move towards its goal of launching its unsupervised FSD service by June 2025 in Austin, Texas, and, soon after, in California as well. After all, Bloomberg is now reporting that Tesla has sought approval to launch a ride-hailing service in the Golden State.

Do note, however, that Tesla's competition is also rapidly catching up. While Tesla bulls are quick to dismiss Waymo's robotaxis as overly reliant on an expensive array of sensors and extensively mapped out routes, it is much more difficult to be as nonchalant about Wayve's robotaxi service, whose cars come equipped with 7 cameras, but no radar, LiDAR, HD maps, or labeling.

This gels with a recent investment note from Needham, whose analysts postulate that Tesla's longer-dated growth levers, particularly in relation to the FSD, robotaxis, and the Optimus humanoid robot, are "more priced in than not," and that the EV giant is operating from a "trailing position" in the autonomous ridesharing and robotics spheres.
