SpaceX goes all-in on steel Starship, scraps expensive carbon fiber BFR tooling
In a wholly unforeseen turn of events, SpaceX has taken the extraordinary step of permanently scrapping both its Port of Los Angeles-based BFR development tent and what seem to be the majority of what it contained, irreparably destroying custom-built tooling meant to support the fabrication of carbon composite BFR spaceships and boosters.
Likely worth anywhere from several to tens of millions of dollars (USD), SpaceX’s advanced BFR production tools were procured from industry-expert Ascent Aerospace sometime in 2017 before being officially delivered to the rocket company’s newly-erected Port of LA tent around April 2018. Situated at the port specifically due to logistical concerns about the high cost of transporting 9m/30ft-diameter objects from SpaceX’s main Hawthorne facilities to a barge for transport east, the company has decided to unequivocally destroy its aerospace-grade composite tooling less than 12 months after accepting delivery. Put simply, this is the best evidence yet that SpaceX – willing or not – has gone all-in on build Starship and Super Heavy out of stainless steel less than six months after CEO Elon Musk began to hint at the program’s utterly radical pivot.

From the very beginning of SpaceX and Elon Musk’s serious pursuit of an entirely reusable launch vehicle capable of transporting dozens of astronauts and passengers to and from Earth and Mars, the plan had been to build the vast majority of the rocket’s booster and spacecraft structures out of advanced carbon fiber composite materials. Above all else, this fundamental architecture was motivated largely by the significant performance gains a rocket could achieve by replacing traditional aluminum tanks and structures with carbon fiber.
For a rocket (and especially an orbital spaceship) meant to somehow make Earth-Mars transport both routine and at least minutely affordable, focusing primarily on the optimization of the mass of cargo delivered relative to the empty weight of the spaceship and booster made (and still does make) a great deal of sense. Assuming that the reusability of a system is roughly constant, the only conceivable way to further lower the cost of price per unit of cargo or passenger ticket would be to increase the usable cargo/passenger capacity for each individual launch, making an extremely light and high-performance rocket the low-hanging fruit target.


The centrality of carbon fiber composites remained with SpaceX’s Sept. 2017 iteration of BFR, downsized by 25% to a diameter of 9m (~30 ft). Around six months later, that commitment to composites was further solidified by the delivery of the first 9m-diameter carbon fiber tooling in March or April 2018. The tooling used to mold and
In the subsequent months of 2018, SpaceX’s BFR and composite R&D team spent tens of thousands of hours building out an ad-hoc advanced composites workshop inside a temporary tent in an industrial area, and ultimately managed to build a number of full-scale carbon fiber segments, including at least one large tank barrel section and the beginnings of a tank dome. In September 2018, that progress was partially revealed alongside the announcement that Japanese billionaire Yasuka Maezawa had purchased the first crewed lunar launch of BFR for several hundred million dollars, set to occur no earlier than 2023.
Two months after indicating that the first BFR “airframe/tank barrel section” would be built out of a “new carbon fiber material”, Musk provided the very first teaser for a “counterintuitive” development that would later be identified as the CEO’s decision to wholly replace BFR’s proposed used of composites with stainless steel and an advanced metallic heat shield. Still more than a little controversial and hard to follow almost half a year later, the feeling at the time was that SpaceX’s eccentric leader had decided to throw away more than 24 months of composite BFR design and development work for an almost entirely unproven alternative approach.
For better or for worse, it appears that SpaceX (or maybe just Musk) has quite literally trashed the most concrete demonstration of a prior commitment to advanced carbon fiber composites, scrapping the vast majority of its composite tooling and perhaps even the prototype BFR segments built in 2018.


It remains to be seen whether the now-permanent decision to pursue a stainless steel design in place of carbon fiber was a very expensive mistake, a stroke of genius, or something in between, However, the undeniably brisk progress made with the BFR’s steel variant in last four or so months bodes well – at a minimum – for Musk’s optimism that this radical change will ultimately result in an operational vehicle far sooner (and presumably cheaper) than the composites route.
Generally speaking, it seems safe to – on the face of it – agree with Musk’s argument that steel should ultimately lend itself far more easily to reusability thanks to its high tolerance for extreme temperatures. Unlike Falcon 9’s aluminum structures (and even the most exotic, advanced carbon fiber composites), certain varieties of stainless steel can weather heating approaching that experienced during orbital reentry with minimal erosion or damage to its mechanical properties. As Musk puts it, the Super Heavy booster’s suborbital trajectory could require almost no heat shielding – and perhaps even paint – at all.
Only time will tell whether the inevitably harsher realities of real-life engineering are so kind. In the meantime, SpaceX is perhaps just hours away from the first attempted static-fire test of a Raptor installed on something approaching flight-hardware, in this case a full-scale Starship hop test prototype.

Elon Musk just confirmed the Tesla and SpaceX merger step everyone was waiting for
Tesla and SpaceX formed special committees to weigh a merger, and Elon Musk supports it.
Elon Musk confirmed Tuesday that Tesla and SpaceX have each formed special committees of independent directors to study a possible merger, the first formal step toward combining the two companies after months of speculation.
Musk made the disclosure during SpaceX’s third quarter earnings call. “Both SpaceX and Tesla have formed special committees to discuss this idea at the request of shareholders,” he said. “Because I’m a conflicted party, I can’t actually be in the discussions of the special committees.” He described the setup as “an odd kabuki dance where two groups of people are talking and I can’t be in the conversation.”
Musk did not hide where he stands. “Do I think it would be a good idea? Yes,” he said, pointing to shared work on super intelligence software, chip design, the Terafab facility in Austin, robotics, mass to orbit and connectivity. “I do think there’s a lot of merit to combining the companies as we are pretty much in the super intelligence singularity.”
He also tried to cool expectations. The committees have not agreed on terms for any transaction, and Musk said assuming a merger is a certainty “would be overstating it.” Any deal would go to shareholders, and on the Tesla side it would need approval from 50 percent of all outstanding shares, not just the shares that are voted. Musk called that “quite a high hurdle.”
That bar has tripped Tesla up before. The company’s 2025 attempt to declassify its board won support from only 39.4 percent of outstanding shares and failed. Musk’s own voting stake sits near 20 percent after he exercised his 2018 options in June, so a deal would need broad backing from institutions and a retail base that often leaves votes uncast.
Timing is another open question. Tesla filed its proxy statement Monday for its December 3 annual meeting, and the ballot has only three items: director elections for Musk, Robyn Denholm and JB Straubel, a say on pay vote and auditor ratification. Barclays analyst Dan Levy had argued that an announcement would need to land by late October or early November to make the annual meeting, as Teslarati noted in its SpaceX earnings preview. With no terms agreed, any vote would likely require its own special meeting.
Elon Musk gives his most telling Tesla-SpaceX merger conversation yet
Musk has been edging toward this for weeks. At the All-In Summit in September, he asked “who can imagine what action one might take when there’s so much close collaboration,” Teslarati reported. Last week’s Roadster unveil, built around SpaceX derived cold gas thrusters, pushed the talk further. The two companies already share the Terafab chip project, and Tesla holds a small SpaceX stake that came from its earlier investment in xAI.
SpaceX brought strong numbers to the conversation. It reported Q3 revenue of $14.58 billion, up 161 percent year over year, with its Super Intelligence segment now its largest at $7.56 billion. A higher SpaceX valuation would shape any exchange ratio Tesla holders are offered.
Tesla reports its own third quarter results after the close on Wednesday, October 21. Investors had already ranked merger timing among the top retail questions for SpaceX’s call, and the committees will almost certainly come up again on Tesla’s.

SpaceX delivers blockbuster Q3 results as Super Intelligence segment booms
SpaceX reported its third-quarter 2026 financial results on October 20, posting the company’s first solidly profitable quarter since going public earlier in the year under the ticker $SPCX.
Revenue reached $14.58 billion, up 161 percent year-over-year from $5.6 billion, and well ahead of consensus estimates in the $12.7 to $12.9 billion range. The results highlight a rapid shift in SpaceX’s center of gravity toward artificial intelligence/super intelligence, while Starlink and traditional space operations continue to show robust progress.
Here are the key financial results for the quarter:
- Revenue of $14.58 billion (+161% YoY)
- Adjusted EBITDA of $8.8 billion (+306% YoY)
- GAAP net income of $4.4 billion (versus a $1.1 billion net loss in the prior-year quarter)
- Adjusted EPS of approximately $0.35 (versus roughly $0.13–0.16 expected)
- Income from operations of $2.8 billion
The AI/SI segment generated $7.56 billion in revenue, an 830 percent year-over-year increase, making it the company’s largest segment for the first time. Growth was primarily driven by the activation of major cloud services agreements, the integration of Cursor (acquired earlier in 2026), and rising usage of Grok models and the newly introduced Grok Bot personal agent.
🚨 SpaceX just reported earnings! Here are some highlights:

Adjusted EBITDA $8.8B (+306% YoY)
GAAP net income $4.4B (vs. prior-year loss; first solidly profitable quarter post-IPO)
Adjusted EPS ~$0.35 vs. ~$0.13–0.16 expectedSegments:
Super Intelligence (SI, formerly AI): $7.56B (+830% YoY) — now the largest segment, driven by cloud contracts, Cursor, and Grok.
Connectivity (Starlink): $5.25B (+69% YoY).
Space: $1.77B.Other highlights:
Starlink subscribers: 13.6M (+89% YoY).
Nameplate compute: 1.7 GW.
Capex: $19.6B (majority AI infrastructure).
Cash & marketable securities: ~$90B.
First revenue-generating Starship mission (26 V3 Starlink satellites, ~10× Falcon 9 downlink capacity per launch).— TESLARATI (@Teslarati) October 20, 2026
SI adjusted EBITDA reached $5 billion, and nameplate compute capacity stood at 1.7 GW at quarter-end, up from 1.4 GW in June and 0.6 GW a year earlier. Capital expenditures totaled $19.6 billion, with the majority allocated to AI infrastructure, including continued expansion of the Colossus facilities.
The Connectivity segment, which primarily surrounds Starlink, produced $5.25 billion in revenue, a 69 percent year-over-year and 22 percent sequentially. These are pleasant results to see and expected, considering how many airlines have adopted Starlink over the past year.
Starlink consumer subscribers reached 13.6 million, an 89 percent increase from the prior year, and a sequential gain of 1.6 million. Consumer average revenue per user improved to $69. Meanwhile, Enterprise and Government revenue also grew strongly, and Starlink is now installed on more than 3,800 aircraft, making internet more accessible and better performing than previous options.
The Space segment also performed well and contributed $1.77 billion in revenue, up 6 percent year-over-year and 84 percent sequentially. A major milestone was the successful first revenue-generating Starship mission (Flight 14), which deployed 26 V3 Starlink satellites. Those satellites added roughly 10 times the downlink capacity of a typical Falcon 9 Starlink launch.
SpaceX completed 12 customer launches during the quarter, including NASA’s Nancy Grace Roman Space Telescope mission, and continued to grow its backlog of crewed, national security, and commercial flights.
CFO commentary noted that the combination of launch leadership, recurring Starlink revenue, and rapid SI expansion is producing meaningful operating leverage.
The company ended the quarter with roughly $90 billion in cash and marketable securities, providing substantial resources for ongoing investment while targeting an investment-grade balance sheet. Sequential revenue nearly doubled from the $7.81 billion reported in the second quarter, illustrating the pace of the AI-driven acceleration. Things are looking strong for SpaceX.
What’s incredibly striking is the fact that SI has grown to be larger than the rest of the company in such a short amount of time. CEO Elon Musk said on the earnings call that Grok Bot is the “fastest-growing product I’ve ever seen,” so it seems that it could be a true keystone of SpaceXSI over the next few years.
Investor's Corner
SpaceX reports its second earnings today: here’s what to expect
SpaceX (NASDAQ: SPCX) will report its second public earnings call today since its IPO earlier this year, and there are a few things we expect to hear about, as well as Wall Street analysts, who have already outlined their expectations for the call.
Wall Street analysts have a consensus of $12.72 billion in revenue and an earnings per share (EPS) of $0.13. These are broken down into three sectors: Space, Connectivity, and AI/SI, which are perceived in this way:
- Space: $1.41 billion
- Connectivity: $4.84 billion
- AI/SI: $6.47 billion
Other outlets cluster near $12.8 or $12.9 billion in revenue and $0.14 – $0.15 EPS. This implies a roughly 65 percent sequential growth from Q2’s $7.81 billion, driven mostly by AI/SI, with the first post-IPO positive EPS expected.
Here are the three things to watch for on the call:
AI Revenue Ramp and the $100B+ ARR target
AI is truly the swing factor for SpaceX, and analysts expect it to roughly double from Q2’s $2.56 billion and become about half of total revenue. Management previously guided to a $100 billion+ annualized run rate by December, including the Cursor acquisition, which was $60 billion, to close the quarter.
Listen for updates on SpaceX’s compute capacity, especially pertaining to its contracts with Google, Anthropic, and others, revenue per watt, any new deals, and Cursor’s early contribution.
Starlink/Connectivity Metrics and Mobile Expansion
Connectivity remains a main profit engine for SpaceX. Subscriber additions will be something to pay attention to, as Q2 ended at 12 million and previews are looking at 14 million for this quarter. Additionally, ARPU trends, enterprise and government growth, and any commentary on Starlink Mobile will be something to pay attention to, especially following the recent low-band spectrum deal and FCC-related constellation approvals.
Capex Trajectory, Cash Burn/FCF, and Starship/Operational Updates
Q2 capex of roughly $18.4 billion weighed on the stock. Investors will look to scrutinize Q3 spending levels, any guidance on the pace into Q4/2027, free cash flow, backlog, and liquidity. Operational color on Starship (Flight 14 milestones and Flight 15 timing/reusability progress), Falcon cadence, and government/NASA contracts are also in focus.
Of course, there will also be some speculation on the potential Tesla-SpaceX merger, but there was nothing mentioned in the company’s proxy it sent earlier this week.
SpaceX will report earnings after market close today and will stream the call on X.
