Tesla’s Cash Burn Deepens as Robotaxi Growth Stalls, Testing Investor Faith
Published on 07/26/2026 at 16:53 | Redaktion boerse-global.de
For a company that just delivered a record number of vehicles, Tesla’s stock is behaving as if the opposite happened. The shares closed at €275.35 on Friday, shedding 17.31% over the past seven trading sessions — a sell-off that has little to do with demand for cars and everything to do with the widening gap between Elon Musk’s futuristic ambitions and the cold math of the balance sheet.
The second-quarter results, released on July 22, told a story of two Teslas. On one side, deliveries hit an all-time high of 480,126 vehicles, pushing revenue up 26% to $28.24 billion. On the other, the operating margin collapsed from 4.1% a year ago to just 1.4%, hammered by price cuts and a sharp drop in revenue from regulatory credits. Adjusted earnings per share of $0.33 missed the $0.52 analysts had penciled in, and for the first time in over two years, free cash flow turned negative — falling to minus $1.1 billion.
That cash-flow reversal is the detail that has rattled investors most. A year ago, Tesla generated $146 million in free cash flow during the same period; in the first quarter of 2026, the figure stood at $1.44 billion. The culprit is a spending spree of historic proportions. Operating expenses surged 47% to $4.35 billion, while capital expenditures hit $5.79 billion — a 142% jump from the $2.39 billion spent in the year-ago quarter. For the full year, Tesla plans to invest over $25 billion, more than double last year’s outlay.
Chief Financial Officer Vaibhav Taneja has already warned that operating expenses will keep rising through 2026 and beyond, signaling that the cash drain is no temporary blip. With an operating margin of just 1.4%, there is precious little room for error. If the core auto business does not stabilize, further quarters of negative free cash flow loom as Tesla funds its AI ambitions.
Should investors sell immediately? Or is it worth buying Tesla?
The Robotaxi Story Loses Momentum
The bull case for Tesla has long rested on a future beyond car sales — robotaxis, humanoid robots, and energy storage. But the numbers from the second quarter suggest that even the most advanced of these bets is struggling to accelerate.
Tesla’s quarterly presentation showed a cumulative paid robotaxi mileage curve that has climbed past 2.4 million miles. On the surface, that looks like progress. Strip out the cumulative effect, however, and a different picture emerges. The second quarter added roughly 900,000 paid miles — exactly the same as the first quarter. Worse, 500,000 of those miles came in April alone, meaning the pace slowed to around 200,000 miles per month in both May and June.
The robotaxi service now operates in seven metro areas across Florida, California, and Texas, but it still lags far behind Alphabet’s Waymo and Baidu’s Apollo Go. Musk himself struck a cautious tone on the earnings call, warning that even a single injury accident would generate global headlines and trigger immediate regulatory pushback. That is not the language of a company on the verge of rapid scaling.
Meanwhile, the Cybercab has entered production at Gigafactory Texas, and Tesla is preparing to pilot the third generation of its Optimus humanoid robot in Fremont, with suppliers reportedly targeting a production rate of 1,000 units per week by September. But these are early-stage projects, and the energy storage and services divisions — while posting record profits — are not yet large enough to offset the pressure on automotive margins.
Technical Signals and the $259.70 Line
The stock’s decline has pushed it deep into technically oversold territory. The relative strength index stands at 27.9, a level that often precedes short-term bounces. The average analyst price target of €373.67 implies roughly 36% upside from current levels, suggesting that a significant portion of Wall Street still believes in the long-term autonomy and AI thesis.

But the market is testing a critical floor. At €275.35, the stock sits just 6% above its 52-week low of €259.70, set in late July. That level has effectively been retested in recent days, and a break below it could open the door to a deeper slide. On the upside, the 50-day moving average at €348.59 represents the first major resistance.
The annualized 30-day volatility of 63.53% underscores just how unpredictable the ride is likely to remain. With the cash burn showing no signs of abating and the robotaxi narrative losing its upward glide path, the coming weeks will hinge on a single question: Are investors willing to keep funding a $1.11 trillion valuation through a period of shrinking margins and negative cash flow, waiting for a payoff that has yet to materialize?
