Why Tesla Stock Fell Despite the Semi Launch

Tesla’s Semi rollout in Sparks, Nevada, gave investors a long-awaited production milestone. It did not resolve two other questions in focus on Friday, September 25, 2026: when supervised Full Self-Driving (FSD) might receive EU-wide authorization, and whether Tesla can scale production of its Optimus robot. Shares closed at $372.11, down $5.83, or 1.54%. The day’s reporting points to competing good and bad news, not a measurable contribution from any single headline. 119354

The EU decision moved beyond October

Tesla had said on September 1 that an EU-wide vote on supervised FSD could potentially take place on October 6. Instead, a report describing the draft committee agenda says it allotted 25 minutes for continued discussion of the Netherlands’ authorization request, with no vote listed. Reuters reported that the next apparent opportunity for a decision is not before December. That is a possible decision window, not a guarantee of a vote or approval. 3544

The Dutch regulator RDW had approved the system nationally in April, and Belgium and several other countries subsequently followed. RDW is also seeking authorization across the bloc. Those national steps do not amount to EU-wide clearance: a bloc-wide rollout requires support from at least 15 of 27 member states representing 65% of the EU population. Reuters had previously documented skepticism among some European regulators about the technology and its claimed safety benefits, despite Elon Musk’s confidence that approval was near. 353334

Optimus raised a separate production concern

Friday’s reversal also coincided with reporting, attributed to The Information, that problems with Optimus robot hands were threatening production goals. A subsequent account described complex hand assembly, supplier constraints and failures of automated equipment. These are reported obstacles, not independently established production totals; the available evidence does not support a precise comparison between Fremont’s output and a year-end target. 4

That distinction matters because the Semi event demonstrated progress on one product while the Optimus report questioned Tesla’s ability to manufacture another at scale. The reports do not establish how much of Friday’s share-price move was caused by robotics concerns rather than the EU delay or other factors. 48

Why the Semi milestone was not enough

Thursday’s event at Tesla’s new Sparks factory put the long-delayed electric truck back in the spotlight. Tesla described the launch as a move toward higher-volume production, with an eventual factory capacity of 50,000 trucks a year. Capacity is not current output: the announcement marked progress, but investors still had to weigh the execution risks elsewhere in Tesla’s plans. 1178

Analyst outlooks underscore why there is no single verdict on the stock. A Stock Analysis snapshot showed a Buy consensus among 43 analysts and an average target of $396.94; an earlier MarketBeat snapshot showed Hold among 46 analysts and a $412.25 average target. They use different samples and dates. Similarly, the forecast of roughly 475,000 third-quarter deliveries, versus an estimate of about 466,000, came from Barclays analyst Dan Levy—it should not be attributed to RBC’s Tom Narayan. 192027

The supported conclusion is narrower than a claim that the Semi launch failed: Tesla delivered a positive truck-production milestone, while the EU timetable slipped and reported Optimus manufacturing problems added uncertainty. Friday’s closing price records the outcome, but cannot isolate the market impact of each development. 9354
