Elon Musk’s upcoming satellite internet service, Starlink, is receiving some opposition from US-based ISPs, with broadband industry groups representing fiber and rural internet providers arguing that the speed of SpaceX’s satellite constellation will likely provide customers with internet speeds that are far too slow. The arguments were presented in a report to the FCC, which claimed that Starlink would hit a capacity shortfall in 2028.
The critical study was commissioned by the Fiber Broadband Association (FBA) and NTCA-The Rural Broadband Association, both of whom are urging the FCC to examine if Starlink should receive funds from the Rural Digital Opportunity Fund (RDOF). The RDOF recently awarded SpaceX $885.51 million over ten years, which should help the private space firm bring Starlink to 642,925 homes and businesses in 35 states.
For its study, the FBA and the NTCA commissioned Cartesian, a business consulting firm, to conduct an engineering analysis of SpaceX’s capability to meet Starlink’s RDOF public interest obligations. Cartesian’s findings were not favorable to SpaceX, with the firm alleging that the Elon Musk-led firm’s internet service will provide speeds that are too slow, among other concerns.
“If SpaceX were to engineer its network to serve only the requisite number of RDOF locations and then serve no other locations (i.e., the network is engineered to serve 70% of 642,925 locations), Cartesian estimates that 56% of SpaceX’s RDOF locations in the low capacity case (average bandwidth usage of 15.3 Mbps per location) and 57% of locations in the high capacity case (average bandwidth usage of 20.8 Mbps per customer)3 will experience service degradation during peak times and not meet the RDOF public interest requirements; further, Cartesian estimates that 25–29% of locations will receive an average of less than 10 Mbps of bandwidth during peak times.”
While the broadband industry group’s letter is strongly worded against Starlink, this does not ensure that the FCC would accept the group’s claims, noted Ars Technica in a report. It isn’t easy to forecast Starlink’s capabilities seven years in advance, especially considering SpaceX’s pace of innovation. Just seven years ago, after all, SpaceX was yet to land and recover a Falcon 9 rocket successfully. Apart from the fact that Starlink may very well be improved as it expands, the FCC may also consider the fact that the Cartesian study was commissioned by entities with a vested interest against Starlink.
SpaceX is yet to issue a statement in response to the Cartesian study. However, the firm did note last week in a petition to the FCC that “Starlink’s performance is not theoretical or experimental.” The Starlink beta currently serves about 10,000 users, and this, according to the private space firm, demonstrates “technical maturity and inherent capacity to support high-throughput, low-latency broadband service to unserved or underserved communities in even the most remote and rural areas of the United States.”

SpaceX Starship just nailed something it’s never done before
SpaceX’s Starship flew successfully Friday, landing both stages and deploying its first Starlink V3 satellites.
Starship’s thirteenth test flight delivered exactly what SpaceX needed with a clean liftoff, two successful stage recoveries, and the first real payload the vehicle has ever carried to space. Booster 20 and Ship 40 lifted off at 5:51 p.m. CT from Starbase, and by the time the mission wrapped roughly an hour later, both halves of the rocket had done exactly what they were supposed to do.
Booster 20 separated from Ship 40 a few minutes into the flight and stuck a controlled splashdown in the Gulf of Mexico about six minutes after liftoff. That is a meaningful turnaround from Flight 12 in May, when the booster lost several engines during its boostback burn before a hard water landing attempt.

Starship 40’s performance was arguably the bigger win. The vehicle deployed the first 20 operational Starlink V3 satellites Starship has ever carried, then flew a suborbital arc to a landing in the Indian Ocean that SpaceX commentator Dan Huot called the company’s softest splashdown yet. “This is a dream scenario for this team that’s trying to get this heat shield data,” Huot said on the live broadcast, according to Space.com’s live coverage. “I’m a little over the moon right now. Wow. Lucky number 13.”
Unlike the mass simulators SpaceX flew on Flight 12, these were production Starlink V3 satellites, meant to extend solar arrays and antennas and attempt to link with the broader constellation before reentering minutes later. Getting real hardware through a full deploy sequence on only the second flight of the V3 generation keeps Starship on schedule for the payload work NASA is counting on for future Artemis lunar landings.
What an awesome launch, really seems like everything went super well and it was all incredibly smooth.

The flight also arrives at a moment when SpaceX needed a win. SPCX has traded below its $135 IPO price since mid-July, as Teslarati reported when the mission slipped to Friday, and short interest has climbed to roughly a third of the tradable float. A clean flight will not fix a balance sheet, but it does answer the one question SpaceX absolutely needed answered this week: whether the fixes made after the July 16 abort would hold up under real flight conditions. They did, on both stages, on the first try after the redesign.
SpaceX has not set a target date for Flight 14, though the company has said it wants to push toward an orbital attempt on the next mission. After Friday, that goal looks a lot more within reach.
Tesla’s Supercharger Diner in Los Angeles dominated the company’s global usage rankings after just one year, proving the concept is more than just a one-off novelty location that will fade away.
The performance could incite the company to build more locations, something that CEO Elon Musk has hinted at for some time.
Tesla’s Supercharger Diner delivered 21.2 GWh of energy in its first year of operation, the company’s head of Charging, Max de Zegher, revealed on X. Of the top 10 most utilized Supercharger locations in Tesla’s global infrastructure, the Diner in Los Angeles was the most used by drivers, and it wasn’t particularly close:
Tesla Diner opened exactly 1 year ago. Inspiring that futuristic places like this exist.
It’s our highest usage Supercharger in the world: 21.2 GWh delivered in a year, 1.6k sessions/day.

On its launch day one year ago, nobody was too sure what the Tesla Diner would be about. It seemed like an interesting concept, and considering it had been in the works for years, it was a highly anticipated launch that many were looking forward to.
Based on its success, we could see additional Diners with Superchargers built throughout the United States, and potentially beyond. Musk has said on several occasions that the company would be willing to bring the Diner idea to more markets.
Tesla makes major change at Supercharger Diner amid epic demand
Of the markets that Musk has mentioned, both Palo Alto and Austin have come to be perceived as ideal selections. However, there are no concrete plans as of now to build new Supercharger Diners anywhere; the location on Santa Monica Boulevard will remain the exclusive spot to pick up Tesla-inspired eats, at least for the time being.
Tesla short sellers won big following the company’s massive fall on Wall Street after it reported subpar Earnings on Wednesday.
Tesla short sellers collected about $4.12 billion in single-day profits on Thursday, according to Bloomberg. Shares fell as much as 15 percent during Thursday’s session. It closed as one of the worst days for Tesla on Wall Street in the past three years.
Investors sold off the stock after Tesla said it would aggressively direct its spending toward AI and its Optimus robot project. The company had record revenues, which were driven by one of the strongest quarters in terms of vehicle deliveries in company history.
However, it missed EPS estimates by reporting just $0.33, a far cry from the $0.53 analysts expected.
S3 Partners reported that about 3 percent of Tesla’s outstanding stock is sold short. Managing Director at S3, Ihor Dusaniwsky, provided the short seller’s potential profit, as well as another figure: shorts have likely had paper gains of $8.92 billion this year, as Tesla shares are down 30 percent in 2026.

Tesla has burned short sellers many times in the past, but the company’s latest Earnings Call was a chance for those skeptics to taste some payback. Although the company gave some very transparent information regarding future projects, the rollout of Robotaxi, Optimus, and Semi, many investors took their profits on Thursday.
Notable short sellers like Michael Burry have been transparent about their skepticism around Tesla shares. Burry just revealed three weeks ago that he had opened up a new short on the stock, stating he shorted Tesla shares at $416.22. “Happy it jumped back to this level,” he said in a blog post.
At the time of publication, Tesla shares were down about 3 percent and the stock was trading at $309.92.
