Selling cars is just the beginning; AI is the ultimate destination.

Recently, Tesla delivered a mixed financial report.

On July 23, Tesla released its second-quarter 2026 financial results. Looking solely at the revenue figures, this was a solid report. In the second quarter of 2026, Tesla delivered 480,000 vehicles, a 25% year-over-year increase and a new all-time high; revenue reached $28.62 billion, up 26% year-over-year, marking the first time annual revenue exceeded $100 billion over the past twelve months. Additionally, service and other business gross profit reached $648 million, up 50% year-over-year, with gross margin rising from 9.2% to 14%, all setting new records.

But if you turn to the income statement, the picture changes: in the second quarter, Tesla's GAAP operating profit plummeted 57% year-over-year from $923 million to $398 million, causing the operating margin to drop directly from 4.1% to 1.4%—the weakest performance Tesla has seen in recent years.

At the same time, a more concerning development is that Tesla’s free cash flow turned negative in the second quarter, reaching -$1.1 billion—the first negative figure since Q1 2024, compared to a positive $146 million in the same period last year and $1.44 billion in Q1 this year. The gross margin, which is of greatest interest to outsiders, stood at 16.8%, a decline of 41 basis points year-over-year.

The day after the earnings report, Tesla's stock price plummeted 14.52%, with its latest market capitalization at $1.2 trillion, losing $200 billion (approximately 1.35 trillion yuan) in a single day.

What’s really going on with Tesla? How should you interpret this earnings report to avoid missing the key points of the story?

The most surprising aspect of the second-quarter earnings report was that Tesla's revenue increased by 26% year-over-year, but its profit declined by 57%.

A careful breakdown of Tesla's earnings report reveals that this is primarily due to three factors:

First, Tesla's carbon credit revenue dropped significantly. In the second quarter, Tesla's carbon credit revenue fell sharply from $439 million in the first quarter to $146 million, a 67% sequential decline. Just one quarter later, carbon credit revenue decreased by $300 million.

For a long time, carbon credits have been a significant source of revenue for Tesla. In the United States, multiple automakers, including General Motors and Stellantis, have purchased carbon credits from Tesla. Since 2015, Tesla has generated over $11 billion in revenue from selling carbon credits. This is nearly pure profit, with marginal costs approaching zero.

But now, policy trends have shifted. Last year, the U.S. House of Representatives passed the comprehensive tax cut and spending bill championed by President Trump, known as the "Big and Beautiful" bill. This legislation eliminated penalties for failing to meet Corporate Average Fuel Economy (CAFE) standards and repealed California’s mandatory electric vehicle sales mandate. As a result, traditional internal combustion engine manufacturers no longer need to spend heavily to purchase carbon credits to avoid fines, directly cutting off Tesla’s crucial source of profit.

William Blair & Co. analysts also predict that Tesla's carbon credit revenue will completely disappear by 2027.

Secondly, research and development and administrative expenses have risen significantly.

The Q2 financial report showed that Tesla's operating expenses rose sharply from $2.955 billion in the same period last year to $4.353 billion, a 47% year-over-year increase. Stock-based compensation surged from $635 million to $1.151 billion, an increase of over 80%, including performance incentives for the CEO in 2025. Research and development expenses also climbed from $1.589 billion to $2.371 billion, up 49% year-over-year, with the reason stated plainly as "AI and other R&D initiatives."

In addition, the $240 million warranty reserve established in the second quarter for cell failures in early-delivery energy storage equipment impacted Tesla’s profitability during the period.

However, what truly sent a chill through the market was the negative free cash flow (-$1.1 billion). Upon closer examination, Tesla’s operating cash flow still stood at $4.697 billion, an 85% year-over-year increase.

The issue isn't with "cash generation capacity," but with the pace of spending. Financial reports show that in the second quarter, Tesla's capital expenditures surged from $2.394 billion a year ago to $5.789 billion—an increase of $3.3 billion.

So where did the money go? Looking at the balance sheet, it appears Tesla is re-entering an "investment phase." The company is simultaneously advancing six or seven initiatives: Cybercab, Optimus, Megafactory Texas, the Austin semiconductor wafer fab, lithium refining, and expanding 4680 battery production.

During the earnings call, Tesla management forecasted that capital expenditures in the second half of 2026 will further increase, with the full-year total exceeding $25 billion, continuing to rise over the next two to three years. Musk characterized this on the call as “the fastest end-to-end industrial expansion cycle in the United States since World War II,” comparable to the industrial breakthrough of Ford’s Model T and the wartime production surge during World War II.

The good news is that Tesla still holds $43.5 billion in cash and short-term investments, a decrease of $1.2 billion quarter-over-quarter, but this is still more than sufficient for short-term needs. The real test is whether this investment can quickly generate commercial returns.

If cars are Tesla's "cash cow," then AI, autonomous driving, and robotics are the key to its $1.2 trillion valuation.

In 2026, Tesla made progress in the commercialization of autonomous driving. Previously, Tesla’s Robotaxi fleet had accumulated over 380,000 miles (approximately 610,000 kilometers) across six cities in two states. More importantly, around the end of 2025, Tesla achieved its first fully unsupervised Robotaxis in Austin.

Compared to Musk’s famous 2019 statement that “a million Robotaxis will be on the road next year,” this progress represents genuine commercial advancement, not just PPTs or empty promises.

During the earnings call, an analyst asked, "Why not prioritize deepening our presence in a single city to increase vehicle scale in that city?"

In response, Ashok Elluswamy, Vice President of AI at Tesla, said that deploying simultaneously across multiple cities is intended to validate the algorithm’s generalizability, demonstrating that the system can adapt to diverse road conditions without requiring city-specific tuning. Additionally, Tesla is prioritizing “total miles driven” over “number of vehicles deployed,” as autonomous vehicles operate around the clock, allowing a small fleet to accumulate vast amounts of real-world mileage. Furthermore, because the Cybercab features an entirely new vehicle chassis, Tesla must first gather driving data specific to this platform before scaling up deployment.

Meanwhile, CFO Vaibhav Taneja added that deploying simultaneously across multiple cities can quickly reveal potential issues in software and operational processes, allowing for early risk mitigation in smaller fleets.

Meanwhile, the adoption rate of Tesla’s FSD is also reaching a turning point. In the second quarter, 55% of customers in North America subscribed to FSD at the time of vehicle delivery. The global total number of paid FSD users has approached 1.5 million, representing a 56% year-over-year increase. Of these, 55% opted for a one-time purchase, while the remaining 45% chose the subscription model.

Also of great interest in this earnings report is the progress of Optimus. Tesla has officially retired the Model S and Model X production lines at its Fremont factory, replacing them with the first-generation Optimus humanoid robot production line. It is understood that the next-generation Optimus V3 will soon begin production at the Fremont facility.

The Model S and X once established Tesla as a benchmark for premium electric vehicles, but now they are making way for Optimus, signaling Tesla’s complete departure from its early narrative of “luxury electric cars” and a full embrace of “embodied intelligence.”

This time, Musk’s statement is clearly different from his usual style—he is proactively lowering expectations. He said, “Mass-producing humanoid robots is the most challenging manufacturing ramp-up in Tesla’s history, with nearly all components being new and no existing supply chain; a large number of processes can only be completed internally.”

Recently, rumors of a merger between Tesla and SpaceX have been circulating widely in the market.

Regarding this, Tesla CEO Musk neither confirmed nor denied during the earnings call. He stated, “The numerous collaborative projects highlighted in this meeting demonstrate that the overlap between our businesses continues to grow, and the Terafab chip factory will become a core strategic initiative for our collaboration. However, earnings calls are not appropriate for discussing mergers and acquisitions; such matters must go through a full compliance process.”

From the collaborative projects mentioned by Musk, the boundaries between the two companies are rapidly blurring: the Grok large model will be integrated into Tesla vehicles to power the operation of Digital Optimus; Starlink terminals will be fully deployed across Cybercabs and eventually expanded to all Tesla models currently on sale; autonomous taxi operations face numerous cellular network dead zones, and Starlink’s global communication capability ensures vehicles won’t shut down due to connectivity loss; onboard Starlink also enables 4K HD live streaming and in-car productivity and entertainment, with per-gigabyte data costs far lower than traditional cellular networks.

Tesla's legal head, Brandon, added that both parties signed a major investment framework agreement earlier this year and will continue advancing key projects such as the Terafab chip factory and digital Optimus.

When pieced together, these details reveal not a collaboration between two independent companies, but rather a unified technological foundation spanning automotive, robotics, AI, aerospace, and satellite communications.

Tesla's history is, in fact, a recurring story of being pushed to the brink—only to rise again.

In 2008, the Roadster nearly bankrupted Tesla; Musk risked his entire fortune to keep it alive. At the time, Tesla bet that electric vehicles could be sexy; in 2018, Tesla struggled through the "production hell" of the Model 3, eventually pulling through thanks to its Shanghai Gigafactory, and growing into the world’s most valuable electric vehicle company.

Now, the nature of the bet has changed. This time, Tesla’s wager is whether it can successfully transform—from a car manufacturer into a super tech conglomerate integrating robotics, autonomous driving, AI chips, end-to-end photovoltaic solutions, and next-generation energy storage.

What truly determines the success of this gamble is not how many Optimus units Tesla can produce this year, nor how many cities Robotaxi will cover next year, but whether Musk can turn the six or seven simultaneous fronts into a self-sustaining whole before market patience runs out.

Elon Musk is best at imagining and storytelling, and he has turned it into reality multiple times in the past. I hope he succeeds again this time.
