Tesla's $25 Billion Factory Blitz: Semi Production Begins as Wall Street Questions the Price Tag
Veröffentlicht: 30.04.2026 um 16:12 Uhr, Redaktion boerse-global.de
Tesla kicked off mass production of its long-awaited Semi truck on April 29, finally delivering on a promise that has lingered for years. The first heavy-duty electric truck rolled off the line at the company's Nevada facility, where a dedicated battery-cell plant now supplies the 4680 cells that had previously been a bottleneck. The timing is no coincidence — the Semi launch arrives just as Tesla reveals an eye-watering $25 billion capital expenditure plan for 2026, a sum that has left investors wrestling with the gap between ambition and near-term returns.
The Numbers That Moved the Market
Tesla's first-quarter results, released alongside the Semi news, painted a picture of operational strength that initially pushed shares up 4% in after-hours trading. Revenue hit $22.4 billion, a 15.8% year-over-year increase but slightly below analyst forecasts. Adjusted earnings per share of $0.41 comfortably beat the consensus estimate of $0.37, while gross margin climbed to 21.1% — the highest in several quarters. Excluding regulatory credits, automotive gross margin improved to 19.2%.
The stock's early gains evaporated within hours. CFO Vaibhav Taneja confirmed that capital expenditures would exceed $25 billion in 2026, a $5 billion increase from prior guidance and roughly three times Tesla's historical annual capex of $8.5 billion in 2025. The shares closed roughly 3.6% lower after the call, leaving the stock down 15% year-to-date — the worst performer among the Magnificent Seven. The relative strength index now sits at 31.5, suggesting oversold conditions.
Six Factories, One Giant Bet
The $25 billion will fund six new factories, artificial intelligence infrastructure, the Cybercab production line, and a dedicated chip fabrication plant in Austin. The centerpiece is Project Terafab, a vertically integrated mega-facility designed to produce more than a terawatt of AI compute capacity annually. Intel formally joined the project on April 7 as a partner. Tesla's fifth-generation AI chip, AI5, is slated for low-volume production at the facility by late 2026, with volume manufacturing beginning in 2027.
Should investors sell immediately? Or is it worth buying Tesla?
The Semi factory in Nevada is already operational, with a long-term target of 50,000 trucks per year. Each long-range Semi can travel roughly 500 miles on a charge, powered by three electric motors. Tesla is building its own charging network for the trucks, starting with a station in Ontario, California, and plans for 66 additional sites across the United States. The company has not disclosed specific delivery targets for 2026.
Robot Dreams and Reality Checks
CEO Elon Musk tempered expectations on several fronts during the earnings call. Production of the Optimus humanoid robot will begin in Fremont in July or August, just months after the last Model S and X rolled off the line. Musk cautioned that initial output would be "very slow" and that the precise production rate is impossible to predict given the robot's 10,000 individual components.
On autonomous driving, Musk delivered a blunt assessment: Hardware 3 is simply incapable of enabling unsupervised Full Self-Driving. The planned Robotaxi rollout by the end of 2026 has been scaled back from "most of the United States" to "roughly a dozen states." Affected customers will receive a discounted upgrade program. Musk does not expect meaningful Robotaxi revenue before 2027.
Tesla at a turning point? This analysis reveals what investors need to know now.
Analyst Divisions Deepen
Wall Street remains split on Tesla's trajectory. Wedbush's Dan Ives maintains an Outperform rating and $600 price target, arguing that the massive spending is a prerequisite for Tesla's role in physical AI. TD Cowen trimmed its target from $519 to $490 but kept a Buy rating. Needham remains cautious with a Hold, warning that the first-quarter margin improvement may partly reflect one-time items.
Tesla's balance sheet provides substantial cushion — net liquidity stands at $35.5 billion. Whether the bets on autonomous driving, humanoid robotics, and chip manufacturing generate the revenue momentum to justify the valuation will likely become clearer in 2027, when Robotaxi revenue and Optimus production are expected to appear in the financial statements for the first time. For now, the Semi's production start offers a tangible milestone, even as the broader investment thesis remains a work in progress.
