Tesla’s (NASDAQ:TSLA) second-quarter for 2021 saw the electric car maker post $11.958 billion in revenue. The results, which were discussed in the Q2 2021 Update Letter, were released after the closing bell on Monday, July 26.
Tesla’s second-quarter was impressive, with the electric car maker producing a total of 206,421 vehicles, an astounding number considering that Q2 was beset by a number of headwinds. The company also delivered 201,250 vehicles comprised of 199,360 Model 3 and Model Y, as well as 1,890 Model S.
Tesla’s strong Q2 results were due in part to the Model Y’s accelerating ramp in the United States and the all-electric crossover’s momentum in China. Tesla also finally started deliveries of the new Model S Plaid and Model S Long Range, which are high-margin vehicles.

The following are the key points in Tesla’s Q2 2021 Update Letter.
Revenue
Tesla beat expectations in Q2 2021, reporting a revenue of $11.958 billion for the second quarter, representing total revenue growth of 98% year-over-year. In comparison, Wall Street expected Tesla’s Q2 2021 revenue to be at $11.299 billion, with the highest estimates pointing to revenue of $12.827 billion and the lowest estimates pointing to $9.5 billion of revenue.
Earnings
Tesla also beat expectations for earnings, with the company posting earnings per share of $1.45 in the first quarter. Wall Street, on the other hand, expected Tesla to report a gain of $0.98 per share.
Profitability
Tesla posted a GAAP operating income of $1.3 billion in the second quarter, with an 11.0% operating margin in Q2 2021. The company also posted $1.1 billion of GAAP net income and $1.6 billion of non-GAAP net income. GAAP automotive gross margin also stood at an impressive 28.4%. This was the first time that Tesla exceeded $1 billion of GAAP net income in its history.
Cash
Tesla had an operating cash flow less CapEx (free cash flow) of $619 million in the second quarter. The company also saw a decrease of $912 million in its cash and cash equivalents, resulting in its war chest now standing at $16.2 billion as of Q2 2021.

Gigafactories
Tesla has provided some updates on the company’s multiple Gigafactories that are under construction. According to Tesla, commissioning has already started in some areas of Gigafactory Texas. Gigafactory Shanghai has completed its transition as Tesla’s primary vehicle export hub as well. Over in Europe, Tesla is focusing on growing import volumes to the region as Giga Berlin continues its equipment tests.
4680 Cells
Tesla’s Q2 2021 Update has provided a number of key updates about the development of the company’s 4680 cells. For one, the company has successfully validated performance and lifetime of its 4680 cells. Manufacturing validation of the 4680 cell production lines at the Kato Road facility are nearing their end as well. Last but not least, internal crash tests of 4680 structural battery packs have so far been successful.
Tesla Energy
Tesla Energy hit its stride in the second quarter, with battery storage deployments tripling in Q2 2021. This increase was primarily due to several Megapack projects. The company noted, however, that while Powerwall demand is exceptional, supply chain challenges have kept the home battery system backlogged. As for the Solar Roof, deployments reached 85 MW in the second quarter, more than tripling year-over-year.

Elon Musk
Elon Musk and SpaceX shrugs off the trading day Wall Street feared most
SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.
SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles
The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.
Cybertruck
Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.
Investor's Corner
SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles
Venture capitalist Chamath Palihapitiya has cautioned investors shorting SpaceX shares, drawing a direct parallel to the intense short-selling pressure Tesla faced in its early public years.
Responding to reports of elevated short interest in the newly public rocket, satellite, and AI company, Palihapitiya noted that similar dynamics played out with Tesla, where aggressive short sellers ultimately “went broke.”
SpaceX (NASDAQ: SPCX) went public on June 12, 2026, in the largest IPO on record, pricing at $135 per share. Shares quickly surged to an all-time high of $225.64 just days later, briefly implying a valuation exceeding $2 trillion. The stock has since retreated sharply amid valuation concerns, lockup expiration fears, and broader market dynamics.
By early August, it traded near $108–$125, representing a roughly 50 percent decline from the peak and bringing the market capitalization closer to the $1.5–1.7 trillion range. On August 4, shares closed up more than 9 percent at $125.33 ahead of earnings before facing pressure in after-hours and premarket trading.
Short interest has climbed dramatically. According to S3 Partners data widely cited in market reports, short positions reached approximately 219.3 million shares by late July, about 34 percent of the limited public float of roughly 640 million shares, and represented a notional value of around $24.6 billion.
Utilization of shares available to borrow hit 95 percent, with borrow fees rising. This level of shorting exceeded the dollar value of short bets against Tesla at the time and built rapidly ahead of two catalysts: the company’s first post-IPO earnings and an August 6 lockup expiration that could free up to 911.5 million additional shares.
CEO Elon Musk has issued warnings of his own. In mid-July, as short interest approached one-third of the float, he posted that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” reiterating his view that the company could ultimately be worth more than Earth if it achieves its goals.
On August 4, just before earnings, Musk responded to the latest short-interest data by saying, “I try to warn them, but they just double down.”
SpaceX delivered its first quarterly results as a public company after the close on August 4. Second-quarter revenue rose 92 percent year-over-year to $7.8 billion, beating consensus estimates near $6.8–6.9 billion.
The net loss narrowed to $541 million, or 9 cents per share, better than the roughly 23–24 cent loss expected. Starlink/connectivity contributed about $4.3 billion (up 66 percent), while the AI business generated $2.6 billion (up roughly 250 percent). Capital expenditures were heavy at $18.4 billion, largely tied to AI infrastructure. Management projected a $100 billion annualized revenue run rate by year-end 2026 and outlined a path toward $1 trillion in annual revenue by 2030.
The combination of Chamath’s historical reminder, Musk’s repeated alerts, and the company’s ambitious growth targets underscores the high-stakes debate surrounding SPCX. Short sellers are positioned for near-term supply pressure from the lockup, while long-term bulls point to Starlink scale, Starship progress, and AI compute expansion as reasons the bears may ultimately face the same fate as many early Tesla skeptics.
