Recently, reports emerged stating that General Motors’ self-driving unit, Cruise LLC, was dismissing nine top executives amid an ongoing probe. A memo from Cruise President Mo Elshenawy, which was shared by the self-driving unit online, shows that the nine executives were but the tip of the iceberg in the company’s efforts to strategize its operations.
Cruise has had a very eventful year. In August, Cruise received approval to deploy its self-driving robotaxis 24/7 in San Francisco. Following an incident when one of the company’s self-driving robotaxis crashed into a firetruck, however, the California Department of Motor Vehicles (DMV) advised Cruise to cut its fleet in the city by 50%.
Things took a turn for the worse in October when a pedestrian, a woman, was initially struck by a human-driven car. The impact was so notable that the woman was thrown into the path of a Cruise robotaxi, which ended up running over the pedestrian. The Cruise robotaxi detected a collision and proceeded to pull over, dragging the woman about 20 feet further. The pedestrian was taken to SF General Hospital with serious injuries.
By late October, the California DMV advised Cruise to halt all its operations in San Francisco. Since then, Cruise has implemented a number of changes. Leaders such as former Chief Executive Officer (CEO) Kyle Vogt and Chief Product Officer Daniel Kan also left the company.
In his memo, Cruise President Mo Elshenawy noted that the company has now updated its operating plans. These updates include a workforce reduction that affects about 24% of the company’s staff. Bloomberg News estimated that Cruise’s workforce reduction efforts would likely affect about 900 full-time workers. Most of the ones affected will be from operations, though some technology positions will also be affected. Engineers, however, will mostly be safe.
Following is Elshenawy’s memo to Cruise staff, as shared by the GM self-driving unit in its official blog. The document covers the company’s decision behind its workforce reduction, as well as what those affected by the update could expect in the coming months.
In October, Cruise paused operations to take time to examine our processes, systems and tools and improve how we operate. While we remain committed to commercialization, we will approach it within a thoughtful and achievable time frame—with safety as our north star.
-
As a result of our updated operating plans, today Cruise shared the difficult news that we are making staff reductions impacting 24% of full-time Cruisers. This reflects our new future and a more deliberate go-to-market path, meaning less immediate need for field, commercial operations and corporate staffing.
As we look forward, the road to successful commercialization is dependent on defining and meeting an exceptional performance and heightened safety bar. Cruise is committed to playing a key role in defining these standards with the input of our regulators, our communities and other AV industry leaders.
We are extremely grateful to the departing employees who have helped further our mission, and the remaining Cruisers who will carry that mission forward in our next chapter.
Below is a letter from Mo Elshenawy, President and CTO of Cruise, that went to all employees today:
Cruisers:
We knew this day was coming, but that does not make it any less difficult—especially for those whose jobs are affected.
Today, we are making staff reductions that will affect 24% of full-time Cruisers, through no fault of their own. We are simplifying and focusing our efforts to return with an exceptional service in one city to start with and focusing on the Bolt platform for this first step before we scale. As a result, we are reducing our employee counts in operations and other areas. These impacts are largely outside of engineering, although some Tech positions are impacted also. As you might have learned, yesterday, we took action to part ways with several SLT members.
-
Craig and I believe this is a necessary step, and our leadership team and the board are fully aligned with how our go-forward U.S. staffing needs will map to the priorities ahead of us, and set up Cruise for the long term. We have also ended additional assignments of contingent workers who support our driverless operations, as we refined our go forward plans.
In a few moments, you will receive an email letting you know whether or not you are affected by this staffing reduction. If you are impacted, you will get details about what happens next in a subsequent email.
Please know that our first priority is to treat departing Cruisers with fairness, and I will describe more about how we are doing that below.
I also want to explain why we are making these reductions, and what this means for Cruise moving forward.
Cruise today vs Cruise moving forward
As we’ve shared, our goal is to focus our work on a fully driverless L4 service that meets a new AV performance bar, prioritize the Bolt platform, relaunch ridehail in one city to start, and enhance our safety standards and processes before we scale. We are ceasing work on the Origin MY24 but not losing sight of our work on future programs. This is very different from our prior plans to expand into more than a dozen new cities in 2024.
As a result of our decision to slow down commercialization, we are restructuring to focus on delivering the improvements to our tech and vehicle performance that will build trust in our AVs.
-
Many of you will be impacted because we aren’t commercializing as quickly, and therefore don’t need support in certain cities or facilities. In other cases, we restructured teams based on the work we’re prioritizing. We didn’t take any of these decisions lightly, though I know that isn’t much of a consolation if you’re someone affected by the actions we are taking today.
How we’re helping departing employees
We know there’s no “good” way to lay off employees, but treating people fairly on their way out was a key principle that guided our approach, and our top priority was determining how we could provide a strong severance package, while treating departing Cruisers with respect. In short, we are offering departing Cruisers pay, at minimum, through April 8, 2024 (approximately 16 weeks), plus continued subsidized health benefits, RSU vesting, the January 5 bonus, and additional immigration support for those holding work visas.
Severance details include:
- Severance pay: Departing employees will remain on payroll through Feb. 12 and are eligible for an additional 8 weeks of pay, with long-term employees offered an additional 2 weeks’ pay per every year at Cruise over 3 years.
- Bonus: All impacted employees will receive their 2023 bonus (eligible target payout) on Jan. 5, 2024.
- Medical, Dental, Vision: we will provide Cruisers and their dependents who are currently enrolled in Cruise benefits the option to receive Cruise-subsidized medical, dental and mental health/EAP benefits through the end of May.
- Perks Wallet: We will give Cruisers two months to access the perks most important to them via our Perks Wallet.
- 401(k): We will give Cruisers two months to continue contributions into their 401(k) plan, including our employer match.
- RSU vesting: All Cruisers, including those impacted and those remaining, will receive their January 15th RSU vest. In addition, we will provide liquidity for all of these January 15th shares in Q1 based on an updated 409A fair market valuation that we will conduct in the first quarter. Tax obligations for these January 15th vested shares will not be incurred until we provide you liquidity for these shares.
- Career support: Departing employees will receive a year-long subscription to LinkedIn Premium, and we will create an opt-in alumni directory to connect potential employers with impacted Cruisers. Cruise Talent Acquisition will also run workshops on resume building, networking, and interview prep with departed Cruisers in the new year.
- Immigration support: We are offering continued time on payroll through March 24 in lieu of a lump-sum severance payment to allow visa holders additional time to help transition and manage their immigration status. Eligibility for the Perks Wallet and 401(k) contributions and match will also continue through this time. We also have dedicated support lined up to help Cruisers based on their needs.
Our message to other employers in the market is that each departing Cruiser is a talented, driven, and mission-focused team member who will contribute and achieve great things elsewhere. They are departing us through no fault of their own. Other companies will be privileged to have these professionals on their teams, as we were privileged to have them here during their time at Cruise.
What’s next
As mentioned, in a few moments, you will receive an email letting you know whether or not you are affected by this staffing reduction, and if you are impacted, you will get details about what happens next. I am so sorry we have to do this by email, as I would prefer that we have a conversation with each of you. Unfortunately, given the scale of this change, this approach allows us to communicate to those who are impacted at the same time. We know you will want to say goodbye to your colleagues, so you will have access to Cruise email and Zoom for the next couple of hours (until 10am PT).
This is one of the hardest days we’ve had so far because so many talented people are leaving. I’m thankful we had the chance to work together, and I know I speak on behalf of so many Cruisers who will be reaching out to those departing to help with our professional networks and references. On behalf of the SLT, the Cruise Board and GM, I’m truly grateful to everyone who has played a role in building Cruise and who has poured so much into the promise of making our roads safer and our world better.

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.
Elon Musk sheds two new bits of detail on Starship after 13th test launch
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 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.
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.
