Update: Lede paragraph date revised to Thursday to reflect accuracy.
Hertz gave several updates on its fleet of Tesla and Polestar all-electric vehicles, which it started offering to customers earlier this year, during its Earnings Call for Q2 2022 held on Thursday.
Hertz expanded its EV offerings to sixteen new cities earlier this month and has experienced widespread success in its EV fleet.
Initial Order of 100,000 Teslas
Hertz initially ordered 100,000 Tesla Model 3 and Model Y vehicles in October 2021. The move was Hertz’s introduction into EV adoption, which has expanded to other automakers, including Polestar, who announced a 65,000 unit deal with the rental agency just months later. The 100,000 vehicle deal was not offered at a discount. However, Hertz has maintained that its adoption of Teslas has resulted in a dramatic spike in interest from renters.
“With respect to EV specifically, over 15,000 Uber drivers to date have rented a Tesla from Hertz, at a minimum rate of $334 per week, comprising over half a million transaction days,” company CEO Stephen Scherr said. “Driver feedback has been positive and they remain drawn to the opportunity as gasoline prices remain elevated and demand for the service among Uber customers is strong. Our Tesla’s enabled Uber drivers could differentiate themselves and to improve upon the quality of their riders experience, and that translates into higher earnings for them.”
20,000 Teslas and Polestar EVs Delivered
Hertz detailed on the call that it has accepted around 20,000 electric vehicles in its fleet since it started taking deliveries of its various EVs. Scherr continued that deliveries are ongoing.
Maintenance Reductions
Electric vehicles are most often noted for their drastic reductions in service compared to combustion engine vehicles, which results in more savings over the lifespan of the car due to fewer moving parts. Hertz is learning that lesson pretty easily, according to Scherr, who stated the company is seeing a roughly 50 to 60 percent decrease in maintenance costs:
“On maintenance, I think Kenny said to you, we are running kind of 50% to 60% of what maintenance costs are on ICE vehicles. That’s roughly in line with where we are. If there’s anyone surprised, it’s probably a slightly higher expense on tires, but not much more, and that’s embedded in the figure I’m giving you. So I would say, overall, we are very pleased with the results. They’re coming in roughly in line with what we thought when we first underwrote the move in this strategic direction.”
Additionally, Kenny Cheung, Hertz’s CFO, also commented on the maintenance cost reductions:
“As for the primary drivers of the year-on-year increase, we experienced higher cost and transportation and fuel, reflecting the effect of broader inflationary trends as well as in maintenance on order fleet. We expect maintenance expenses to moderate as our fleet continues to grow younger. On the forward, we anticipate additional operating leverage as more expensive third-party labor strategically replaced with Hertz employees and we further reduced maintenance expense as we rejuvenate the fleet and continue to grow our number of EVs.”
Return Customers
Scherr said that customers seem to be more interested in renting Teslas over and over again, which has translated to an increase in repeat clients for the company. “I think we have schooled our customers on how to use them, so much so that I think there’s an embedded tether there,” he said, referring to Tesla’s key card. “They’re coming back to use the car and rent the car more frequently. And I think all of those are expressions of the first mover edge that we have around EVs.”
Consumers may be hesitant to try a new, technologically-advanced product, especially when dealing with a car. However, it seems that once Hertz’s rental clients make the jump to try an EV, they’re much more likely to come back simply because of the ease of access and features.
Less Vehicle Depreciation
Company executives also stated that the depreciation of EVs in their rental fleet is moving at a slower pace than its ICE vehicles. Cheung said that the performance of the EV fleet early on has the company “more confident” in the economics of the BEVs compared to their ICE offerings.
This is comparable to the scenario that police departments have when purchasing an EV. Initially, the cost of a quality electric vehicle is somewhat higher than an ICE vehicle. Over time, as fuel costs, maintenance, and other costs pile up, the EVs will be more advantageous to Hertz and other adoptees in the books. The cost of savings is exponentially more in an EV compared to an ICE car. This has been proven on several occasions, including with the Westport, Connecticut Police Department.

SpaceX has solved Starship’s biggest challenge, Elon Musk says
Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.

SpaceX is coming for wireless giants with Starlink Mobile
SpaceX COO Gwynne Shotwell outlined ambitious plans for Starlink Mobile during the company’s August 4 Earnings call, signaling a direct challenge to U.S. wireless giants like AT&T, T-Mobile, and Verizon.
Shotwell noted that the three companies generate roughly $600 billion in combined annual revenue. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said. “We will eliminate dead zones leveraging the satellites in orbit. It will be better during any natural disaster… I’m quite excited about Starlink Mobile.”

SpaceX intends to combine its satellite constellation with terrestrial infrastructure. The company has acquired about 65 MHz of spectrum from EchoStar and plans to deploy next-generation Starlink Mobile satellites in 2027, with upgraded service targeted for the end of that year.
Shotwell described the enhanced network, leveraging more satellites and spectrum, as potentially “100 times better” than the current direct-to-cell offering, which already supports basic texting and app-based voice/video in coverage gaps through partnerships. She also indicated plans for low-cost cellular base stations that could integrate with existing Starlink dishes, creating a hybrid system for broader capacity in urban, suburban, and rural areas.
For the general public, Starlink Mobile promises significant advantages. Satellite connectivity can fill gaps where traditional cell towers fail, delivering service in remote locations, mountains, or during outages caused by storms, wildfires, or infrastructure damage—conditions in which ground networks often collapse.
Users could enjoy more consistent coverage without relying solely on dense tower builds, potentially at competitive prices as SpaceX scales. The hybrid approach aims to support full mobile services, including higher-speed data, while working with unmodified smartphones over time.
These developments revive long-standing but unfounded rumors of a Musk-developed “Tesla phone.” Speculative claims of a “Pi Phone” or similar device with built-in Starlink connectivity have circulated for years on social media, often featuring fabricated images and details. Elon Musk has repeatedly denied any such plans, stating Tesla has no intention of entering the smartphone market unless forced by extreme circumstances with app stores.
No official product, filings, or development announcements have ever materialized; the rumors remain hoaxes.
The announcement quickly pressured telecom stocks. Shares of AT&T, Verizon, and T-Mobile fell between roughly 2 and 4 percent in after-hours and premarket trading as investors weighed the competitive threat from a hybrid satellite-terrestrial network.
While execution challenges remain—spectrum deployment, infrastructure rollout, and regulatory hurdles—Shotwell’s remarks mark SpaceX’s clearest signal yet of entering the consumer mobile market as a full competitor.
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.
