Tesla’s Elon Musk shares new insights on “funding secured” tweet as messages with Saudi PIF are revealed
Elon Musk recently shared some insights about his infamous 2018 “funding secured” tweet, which he posted when he announced his intentions to take Tesla private. The Tesla CEO’s recent comments came as text messages between Musk and the Saudi Arabia Public Investment Fund Head were shared online.
The text messages between Musk and the Saudi PIF Head Yasir Al-Rumayyan were revealed as part of a 300-page motion filed late last week by Alex Spiro, the Tesla CEO’s lead attorney. The messages were part of Musk’s deposition with the US Securities and Exchange Commission, which accused the CEO of securities fraud.
In August 2018, Musk announced on Twitter that he was looking to take Tesla private at $420 per share (pre-split) and that he had funding secured. A blog post published soon after explained that Musk’s reference to funding being secured came from previous talks with the Saudi PIF. Musk eventually walked away from the take-private deal, despite Tesla’s financial advisers coming up with a possible list of investors which included Silver Lake and Volkswagen AG.
A look at Musk’s texts to the Saudi PIF Head showed that the CEO was extremely adamant about the sovereign fund confirming that it had shown interest in helping Tesla become a private company. The initial messages shared by Musk’s attorney were calm enough, with the Saudi PIF head confirming that any Tesla venture in Saudi will be 100% owned by the EV maker with no strings attached.
The next messages, which seemed to follow a report which alleged that the Saudi PIF had no interest in helping Tesla go private, were more aggressive.
-->During his appearance at TED 2022, Musk noted that he has an obsession with the truth. This is something that was extremely evident in his texts with the Saudi PIF Head. Musk confronted Al-Rumayyan about the report, noting that “This is false.” The Saudi PIF Head confirmed Musk’s statement, noting that the report was “Not true” and that “Nobody talked to them (the media).” The Saudi PIF eventually issued a statement, but Musk was not happy with its content and tone.
“This is an extremely weak statement and does not reflect the conversation we had at Tesla,” Musk sternly wrote, also adding later on that the Saudi PIF was “throwing me under the bus.”
Al-Rumayyan’s attempts at placating the Tesla CEO were evident in later messages, with the PIF Head assuring Musk that he was a friend and thus must not be treated like an enemy. “The last thing I want to do is ‘throw you under the bus.’ I am your friend. So, please don’t treat me like an enemy,” the PIF Head wrote to Musk.
Despite the back and forth, however, Musk remained aggravated about the situation. Even after Al-Rumayyan shared another article, Musk noted that the piece was “weak sauce and makes me sound like a liar.” Musk then noted that “There will be no further communication unless you fix the public perception of wishy washy support and interest from the PIF.” Al-Rumayyan’s last messages to Musk shared in Spiro’s filing stated that the Saudi PIF would be working on a statement, a move that the Tesla CEO stated meant “a great deal.”
In recent Twitter posts, Musk shared some more insights on his “funding secured” tweet. According to Musk, and just as the CEO stated in his text messages from 2018, “the head of Saudi PIF committed unequivocally to take Tesla private with me, as witnessed by the Tesla CFO and several others. That is why I said funding was secured.” Musk also posted some fresh criticism of the SEC’s San Fransisco Office, which he described as “puppets” of Wall Street short seller sharks.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
