SpaceX’s BFR officially updated with new fins/legs, canard wings, and more
Speaking before a crowd of roughly 100 members of the press and even more SpaceX employees, CEO Elon Musk and lunar tourism customer Yusaku Maezawa presented and answered questions for more than an hour and a half, over the course of which Musk made public a number of updates to the company’s BFR booster and spaceship.
Maezawa, on the other hand, revealed a wholly unexpected plan for private lunar tourism deemed #dearMoon, built upon the goals of both (partially) funding development of BFR and placing a group of 6-8 international artists aboard a SpaceX spaceship for a journey around the Moon as early as 2023.

Lacking no ambition, both BFR and #dearMoon have a vast amount of work to complete before their aspirations can be realized. Foundational to an unprecedented private voyage around the Moon, BFR is where this story begins, and SpaceX’s latest 2018 variation on the concept has departed from the 2017 vehicle’s design, with the majority of those changes centering around the upper-stage spaceship, known as BFS.
Those changes can generally be sorted into three main categories: new wings and fins, new operational strategies for spaceship landings, and new a Raptor engine layout.

Wings and fins
The most immediately visible difference between the spaceships of 2017 and 2018 can be found with both crafts’ aerodynamic surfaces and control implements. BFR (2018) now features three distinct fins in a tripod configuration, although Musk stated that the tail fin was scarcely a fin at all and essentially present for the sole purpose of being the third landing leg. Perhaps the most unusual feature of these new tripod fins is that the lower pair have been designed to be massive, agile control surfaces necessary for reentry and landing on planets or moons with significant atmospheres. Those three fins will simultaneously act as landing legs and critical control surfaces while operating in an atmosphere.
Additionally, BFR (2018) has been updated to include a pair of forward canards that will effectively act as a stand-in for grid fins on the spaceship, whereas the booster will simply have traditional titanium grid fins, judging from an official render of the full rocket. Compared with the delta wing or stubby winglets of 2016 and 2017 variants, BFR (2018) will have far more aerodynamic control authority, improving the versatility and stability of the vehicle during atmospheric reentry, flight, and landing on Mars, Saturnian moon Titan, and – most importantly – Earth.

Stay tuned for additional discussion of spaceship landings, changes to SpaceX’s Raptor engine strategy, and more later this week.

SpaceX IPO could push Elon Musk’s net worth past $1 trillion: Polymarket
The estimates were shared by the official Polymarket Money account on social media platform X.
Recent projections have outlined how a potential $1.75 trillion SpaceX IPO could generate historic returns for early investors. The projections suggest the offering would not only become the largest IPO in history but could also result in unprecedented windfalls for some of the company’s key investors.
The estimates were shared by the official Polymarket Money account on social media platform X.
As noted in a Polymarket Money analysis, Elon Musk invested $100 million into SpaceX in 2002 and currently owns approximately 42% of the company. At a $1.75 trillion valuation following SpaceX’s potential $1.75 trillion IPO, that stake would be worth roughly $735 billion.
Such a figure would dramatically expand Musk’s net worth. When combined with his holdings in Tesla Inc. and other ventures, a public debut at that level could position him as the world’s first trillionaire, depending on market conditions at the time of listing.
The Bloomberg Billionaires Index currently lists Elon Musk with a net worth of $666 billion, though a notable portion of this is tied to his TSLA stock. Tesla currently holds a market cap of $1.51 trillion, and Elon Musk’s currently holds about 13% to 15% of the company’s outstanding common stock.
Founders Fund, co-founded by Peter Thiel, invested $20 million in SpaceX in 2008. Polymarket Money estimates the firm owns between 1.5% and 3% of the private space company. At a $1.75 trillion valuation, that range would translate to approximately $26.25 billion to $52.5 billion in value.
That return would represent one of the most significant venture capital outcomes in modern Silicon Valley history, with a growth of 131,150% to 262,400%.
Alphabet Inc., Google’s parent company, invested $900 million into SpaceX in 2015 and is estimated to hold between 6% and 7% of the private space firm. At the projected IPO valuation, that stake could be worth between $105 billion and $122.5 billion. That’s a growth of 11,566% to 14,455%.
Other major backers highlighted in the post include Fidelity Investments, Baillie Gifford, Valor Equity Partners, Bank of America, and Andreessen Horowitz, each potentially sitting on multibillion-dollar gains.

SpaceX considering confidential IPO filing this March: report
The filing could pave the way for a June listing at a valuation that may exceed $1.75 trillion.
SpaceX is reportedly preparing to confidentially file for an initial public offering (IPO) as soon as March. The filing could pave the way for a June listing at a valuation that may exceed $1.75 trillion, potentially making it the largest IPO in history.
The update was initially reported by Bloomberg News, which cited information shared by people reportedly familiar with the matter.
As per the publication, a confidential filing allows a company to receive regulatory feedback before publicly releasing its financials. Bloomberg’s source, however, noted that the timing of SpaceX’s IPO is still under discussion and plans could change.
SpaceX did not immediately respond to requests for comment.
A March submission would mark the clearest step yet toward bringing Elon Musk’s private space company into public markets. People familiar with the preparations said the offering could raise as much as $50 billion. That would surpass the $29 billion debut of Saudi Aramco in 2019, currently the largest IPO on record.
Major banks including Goldman Sachs Group Inc., JPMorgan Chase & Co., Morgan Stanley, and Bank of America Corp. are reportedly positioned for senior roles in the transaction. SpaceX is also said to be considering a dual-class structure that would allow insiders, including Musk, to retain enhanced voting control.
Satellite communications provider EchoStar Corp., which holds a stake in SpaceX, reportedly saw its shares rise following news of the potential filing.
At a valuation exceeding $1.75 trillion, SpaceX would immediately have a larger market cap than all but five of the companies traded in the S&P 500 index. That figure would place it ahead of Meta Platforms Inc. and Tesla Inc. by market capitalization, trailing only a small group of mega-cap firms such as Apple Inc. and Microsoft Corp.
The scale of the proposed valuation reflects SpaceX’s dominance in orbital launch services and its Starlink satellite network, which serves millions of users globally. The company has also outlined long-term expansion plans tied to higher Starship launch cadence, orbital infrastructure, and lunar development initiatives.

Elon Musk outlines plan for first Starship tower catch attempt
Musk confirmed that Starship V3 Ship 1 (SN1) is headed for ground tests and expressed strong confidence in the updated vehicle design.
Elon Musk has clarified when SpaceX will first attempt to catch Starship’s upper stage with its launch tower. The CEO’s update provides the clearest teaser yet for the spacecraft’s recovery roadmap.
Musk shared the details in recent posts on X. In his initial post, Musk confirmed that Starship V3 Ship 1 (SN1) is headed for ground tests and expressed strong confidence in the updated vehicle design.
“Starship V3 SN1 headed for ground tests. I am highly confident that the V3 design will achieve full reusability,” Musk wrote.
In a follow-up post, Musk addressed when SpaceX would attempt to catch the upper stage using the launch tower’s robotic arms.
“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk clarified.
His remarks suggest that SpaceX is deliberately reducing risk before attempting a tower catch of Starship’s upper stage. Such a milestone would mark a major step towards the full reuse of the Starship system.
SpaceX is currently targeting the first Starship V3 flight of 2026 this coming March. The spacecraft’s V3 iteration is widely viewed as a key milestone in SpaceX’s long-term strategy to make Starship fully reusable.
Starship V3 features a number of key upgrades over its previous iterations. The vehicle is equipped with SpaceX’s Raptor V3 engines, which are designed to deliver significantly higher thrust than earlier versions while reducing cost and weight.
The V3 design is also expected to be optimized for manufacturability, a critical step if SpaceX intends to scale the spacecraft’s production toward frequent launches for Starlink, lunar missions, and eventually Mars.
