On Friday, the United Auto Workers (UAW) union entered its 15th day on strike, accompanied by additional walkouts of General Motors (GM) Ford plants. Stellantis, the parent company of Chrysler, Dodge Ram and Jeep, managed to avoid heightened strikes after reportedly making some progress on contract negotiations.
After the UAW said last week that it would escalate strikes if progress wasn’t made on new contracts, the union officially ordered workers to walk off the job at two assembly plants on Friday: one run by Ford in Chicago, Illinois and another run by Stellantis in Lansing, Michigan, Reuters reports. Stellantis avoided the escalated strikes after UAW President Shawn Fain said the automaker made some last-minute concessions.
The news brings the total number of striking workers up to about 25,000, with the historic strike now in its third week. This is the first time in history that auto strikes have targeted all three of the automakers at once, with the UAW strategically striking at key facilities to disrupt supply chains and force negotiation.
The additional walkouts also mark the second Friday on which additional UAW workers vacated their work sites, with employees walking out of 38 more GM and Stellantis facilities on September 22.
Following the updated walkouts on Friday night, Ford CEO Jim Farley and GM CEO Mary Barra laid into the UAW.
“It’s clear that there is no real intent to get to an agreement,” Barra said.
Yahoo Finance reported on Friday that Farley said the UAW was holding an agreement “hostage” over battery plants, adding that the union’s demands “could have a devastating impact on our business.”
Farley recently also stated that the union’s demands would bankrupt Ford if enacted. Tesla CEO Elon Musk reiterated a similar point this week, saying a 32-hour work week combined with a 40-percent wage hike would be a “sure way” to make the three automakers go bankrupt.
“I need to be clear about one thing, because the UAW is scaring our workers by repeating something that is factually not true, none of our workers today are going to lose their jobs due to our battery plants during this contract period or even beyond this contract,” Farley said. “In fact, for the foreseeable future, we will have to hire more workers as some workers retire in order to keep up with the demand of our incredible new vehicles.”
The union responded that neither Farley nor Barra showed up to bargaining this week.
“We want to get agreements,” Fain said on Friday outside the Lansing GM plant. “We have been there every day 24/7 since the middle of July, we have been there every day. It’s ironic that some of these CEOs make these statements and literally the CEO of Ford has been in probably three meetings over the course of these nine or 10 weeks.”

Ford Supply Chain Officer Liz Door said that if strikes continued, we could see as many as 300,000 to 500,000 employees laid off across the auto industry, especially in auto supply positions. Farley said that the 125,000 jobs held by Ford suppliers would also be put “at risk” without a deal.
In a separate report, Reuters also noted that the UAW dropped charges previously filed against GM and Stellantis with the National Labor Relations Board (NLRB), which alleged unfair labor practices at the two companies and claimed that the companies weren’t bargaining in good faith.
The UAW represents about 150,000 workers at the three auto companies, and the current strikes make up about 17 percent of the total figure. The UAW is demanding the following in updated union contracts:
- 40-percent wage hikes over four years
- 32-hour work weeks
- Eliminating tiered wage systems requiring several years to reach top wages
- Restoring traditional pension plans
- Restoring wage cost-of-living-adjustments (COLA)
- Improved vacation, retirement and family leave
The automakers have offered wage increases of about 20 percent in contracts over the four years, though negotiations reportedly remain far apart.
Some expect the situation to positively affect non-unionized electric vehicle (EV) maker Tesla, though others point out that the strikes are likely to make wages — and subsequently car prices — increase alongside those of the three legacy automakers. Among the topics regularly discussed during negotiations is the fact that EVs have fewer parts than gas cars and thus will require fewer workers in the future.

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.
