SpaceX’s Falcon Heavy eyed by Europe/Japan as ULA nails spectacular Delta Heavy launch
According to RussianSpaceWeb, SpaceX’s Falcon Heavy rocket is under serious consideration for launches of major European and Japanese payloads associated with the Lunar Orbital Platform-Gateway (formerly the Deep Space Gateway).
Currently targeting launch readiness in the mid-2020s, those heavy scientific and exploratory government payloads are eyeing Falcon Heavy at the same time as the United Launch Alliance’s (ULA) Delta IV Heavy – the most powerful operational rocket prior to FH’s debut – is busy wrapping up a scientific launch for NASA and prepping for another launch in September for its singular anchor customer, the National Reconnaissance Office (NRO).

A breathtaking mission to the sun
United Launch Alliance (ULA) has just completed the ninth successful launch of its Delta IV Heavy rocket, originally developed by Boeing in the 1990s and debuted in 2004 before the company’s launch vehicle subsidiary joined forces with Lockheed Martin’s own rocket branch. Delta Heavy’s August 12th mission saw the rocket send a small NASA payload known as Parker Solar Probe (PSP) on a trajectory that will eventually place the craft closer to the Sun than any human-made object before it. In pursuit of a better understanding of how exactly our solar system’s namesake functions and behaves, PSP will also become the fastest object ever created by humans, traveling at an extraordinary 200 km/s (120 mi/s) at the zenith of its deepest periapses (the point at which PSP is closest to the sun).
In a fitting send-off for the small heat-shielded spacecraft, Delta IV Heavy’s launch was a spectacle to behold, with clear skies and the cover of darkness combining to magnify the best of the rocket’s telltale features. Upon ignition of its three massive RS-68 rocket engines, each producing over 700,000 lb-ft of thrust, the rocket is held down for several seconds in a process that famously culminates in what appears to be self-immolation just before liftoff, a consequence of the rocket burning off excess hydrogen fuel expelled during the ignition process. Unlike Falcon 9’s dirtier kerosene-oxygen combustion, Delta Heavy’s hydrogen and oxygen fuel produce a flame that is nearly transparent, aside from a bright orange tint created by materials in each engine’s ablative (read: designed to disintegrate) nozzle.

While Delta IV Heavy has used one of its other nine successful launches for a NASA payload (a test flight of the Orion capsule), all seven remaining missions were conducted for the USAF (1) and the National Reconnaissance Office (NRO; 6), and all six remaining missions on the rocket’s manifest also happen to be for the NRO. Put simply, Delta IV Heavy would not exist today if the NRO did not have an explicit and unflappable need for the capabilities it offers. The primary downside is cost: DIVH costs at least $350 million and usually more than $400m per launch. Thankfully for ULA, the NRO has very few problems with money, and the agency’s estimated annual budget of $10 billion (2013) is more than half of NASA’s entire budget.
After Falcon Heavy’s successful debut, Delta IV Heavy’s monopoly over heavyweight NRO and USAF payloads is rapidly coming to an end, and both agencies are almost certainly attempting to equally quickly certify SpaceX’s newest rocket for critical national security space (NSS) launches. With that influx of the slightest hint of competition, Delta IV Heavy’s ~$400 million price tag starts to look rather painful in comparison to Falcon Heavy’s cost ceiling of around $150 million, potentially much less in the event that 1-3 of its boosters are recoverable. That competition likely won’t kill Delta IV Heavy, thanks entirely to the anchor support of the NRO, but it most certainly will guarantee that Delta Heavy is retired the moment ULA’s next-gen Vulcan rocket is ready to take over, likely no earlier than 2024.
Outside of the NRO, however, there is a surprising amount of interest in Falcon Heavy for interesting (and heavy) government payloads, particularly with respect to the NASA/ESA/JAXA/Roscosmos cooperative lunar space station, known as the Lunar Orbital Platform-Gateway.
Falcon Heavy enters the mix
The first payload considering Falcon Heavy for launch services is the Japanese Space Agency’s (JAXA) HTV-X, and upgraded version of a spacecraft the country developed to assist in resupplying the International Space Station (ISS). HTV-X is primarily being designed with an ISS-resupply role still at the forefront, but Russianspaceweb recently reported that JAXA is seriously considering the development of a variant of the robotic spacecraft dedicated to resupplying the Lunar Orbital Platform-Gateway (LOPG; and I truly wish I were joking about both the name and acronym).

As the name suggests, LOPG is fundamentally a shrunken, upgraded copy of the present-day International Space Station but with its low Earth orbit swapped for an orbit around the Moon. Why, you might ask? It happens that that question is far less sorted at this point than “how”, and there’s a fairly strong argument to be made that NASA is simply attempting to create a low-hanging-fruit destination for the chronically delayed SLS rocket and Orion spacecraft it routinely spends ~20% of its annual budget on. The alternatives to such a crewed orbital outpost are actually landing on the Moon and building a base or dramatically ramping development of foundations needed to enable the first human missions to Mars.

Regardless of the LOPG’s existential merits, a lot of energy (and money) is currently being funneled into planning and initial hardware development for the lunar station’s various modular segments. JAXA is currently analyzing ways to resupply LOPG and its crew complement with its HTV-X cargo spacecraft, currently targeting its first annual ISS resupply mission by the end of 2021. While JAXA will use its own domestic H-III rocket to launch HTV-X to the ISS, that rocket simply is not powerful enough to place a minimum of ~10,000 kg (22,000 lb) on a trans-lunar insertion (TLI) trajectory. As such, JAXA is examining SpaceX’s Falcon Heavy as a prime (and affordable) option: by recovering both side boosters on SpaceX’s drone ships and sacrificing the rocket’s center core, a 2/3rds-reusable Falcon Heavy should be able to send as much as 20,000 kg to TLI (lunar orbit), according to comments made by CEO Elon Musk.

That impressive performance would also be needed for another LOPG payload, this time for ESA’s 5-6 ton European System Providing Refueling Infrastructure and Telecommunications (ESPRIT) lunar station module. That component is unlikely to reach launch readiness before 2024, but ESA is already considering Falcon Heavy (over its own Ariane 6 rocket) in order to save some of the module’s propellant. Weighing 6 metric tons at most, Falcon Heavy could most likely launch ESPRIT while still recovering all three of its booster stages.
Regardless of the outcomes of those rather far-off launch contracts, it’s clear that some sort of market exists for Falcon Heavy and even more clear that its injection of competition into the stagnant and cornered heavy-lift launch segment is being globally welcomed with open arms.

SpaceX’s amended S-1 is sparking a major Tesla merger conversation
A single line in SpaceX’s amended S-1 just sent Tesla stock down 5% in one day.
A single line buried in SpaceX’s amended S-1 filing is doing more to move Tesla’s stock price than anything Tesla itself has announced in months. The clause, disclosed as SpaceX prepares for what could be the largest IPO in Wall Street history, states that the company “may issue a significant amount of equity in connection with future transactions.” While this may be seen as boilerplate language in S-1 filings, the historical ties between SpaceX and Tesla, and with Elon Musk reportedly discussing a possible merger with close colleagues, investors are interpreting it as something closer to a signal.
The concern among institutional investors like Gary Black, managing director of The Future Fund, pointed directly to the amended filing on X, saying it “strongly suggests more SPCX equity will be issued,” which could potentially be used to acquire Tesla. He estimated such a deal could be 28% dilutive to Tesla shareholders since SpaceX would likely command a significantly higher valuation multiple. Black added that institutional investors he knows hate the idea of a combination because they prefer pure plays over conglomerates, which he said “nearly always gravitate to the lowest common multiple.”
The Tesla and SpaceX merger everyone is talking about is quietly building
The bull case runs the math differently. Tesla influencer and retail shareholder advocate AleXandra Merz pushed back on what she called a widespread misunderstanding of how merger-of-equals deals actually work. Rather than simply splitting the difference between two market caps, a merger exchange ratio is negotiated based on relative fair market values, meaning the lower valued company typically sees its stock reprice upward toward the deal value.
Under her model, SpaceX enters at a $2.5 trillion valuation and Tesla at $1.6 trillion, producing a combined entity worth $4.1 trillion split evenly between both shareholder groups. That implies Tesla’s side of the deal would be valued at $2.05 trillion, a gain of roughly $450 billion from its current market cap. She cited Dow-DuPont and CBS-Viacom as historical examples of how markets reprice both companies toward the announced exchange ratio after a deal is unveiled.

The SpaceX S-1 amendments also revealed just how much financial infrastructure already binds the two companies together. As Teslarati has reported, SpaceX purchased $697 million in Tesla Megapacks, $131 million in Cybertrucks, and the two companies have shared supply chain resources, and semiconductor fabrication plans since well before any merger conversation became public. A retail poll by Tesla influencer Sawyer Merritt is finding that 36% of respondents do not plan to buy SpaceX shares at IPO and 15.3% saying their decision depends on the valuation.

Whether the merger happens or not, the amended filing is seemingly moving markets and sharpened a debate that is no longer theoretical. SpaceX is weeks away from trading publicly, and Tesla shareholders are now watching every word of every filing for clues about what Musk plans to do next.
Elon Musk has firmly denied recent media reports suggesting that SpaceX has reduced its target valuation for an upcoming initial public offering.
The denial came directly from the SpaceX and Tesla frontman on his social media platform X, where he responded with a single word, “False,” to a post from ZeroHedge that cited Bloomberg sources.
This swift rebuttal underscores Musk’s ongoing effort to manage speculation surrounding one of the most anticipated market debuts in recent history.
False
— Elon Musk (@elonmusk) May 29, 2026
According to the disputed reports, SpaceX had lowered its IPO valuation goal to at least $1.8 trillion from previous ambitions exceeding $2 trillion.
The claims emerged amid growing anticipation for the company’s confidential S-1 filing, which positions it for a potential public listing as early as June.
Some had pointed to strong revenue growth, particularly from the Starlink satellite internet service, which contributed heavily to the firm’s 2025 figures of $18.7 billion. Yet challenges persist in other areas, including substantial investments and losses tied to ambitious projects like Starship development and artificial intelligence initiatives, which plan to make life multiplanetary eventually.
Musk’s response highlights a pattern in which he actively counters what he views as inaccurate portrayals of his companies’ trajectories.
SpaceX, already valued privately at extraordinary levels, stands as a cornerstone of Musk’s empire alongside Tesla and xAI. The entrepreneur has long emphasized the transformative potential of reusable rockets and global broadband access, factors that fuel investor enthusiasm despite operational hurdles.
By rejecting the valuation downgrade narrative, Musk signals confidence in SpaceX’s fundamentals and its readiness for public markets on terms favorable to its long-term vision. People have been waiting a very long time to invest in SpaceX, and the valuation, as well as the introductory share price, is not going to need adjusting.
They’ll have plenty of suitors.
This episode reflects broader dynamics in the technology sector, where rumors often swirl around high-profile entities. Musk’s direct engagement with media narratives serves to maintain transparency and control the narrative around his ventures.
As SpaceX prepares for greater scrutiny in public markets, the founder’s denial reinforces optimism about its prospects. Supporters argue that the company’s innovative edge positions it for enduring success, far beyond short-term valuation debates. With the denial now public, attention turns to forthcoming regulatory filings that could provide clearer insights into SpaceX’s strategy and financial health.
The coming weeks promise to reveal more about how SpaceX will transition into a publicly traded powerhouse.

The Tesla and SpaceX merger everyone is talking about is quietly building
Tesla and SpaceX may be closer to merging than Wall Street or either company is admitting.
Elon Musk has reportedly discussed merging Tesla and SpaceX with people close to him, according to CNBC, which cited sources familiar with the conversation. Tesla employees have long expected such a transaction and the topic is openly discussed internally, according to internal sources. With SpaceX is days away from kicking off its Wall Street roadshow for what could be the largest IPO in market history, this would be the first time the company will have public market currency to execute a stock-for-stock deal with Tesla.
The financial logic for a merger would make sense. A combined SpaceX and Tesla would create a conglomerate spanning rockets, satellites, electric vehicles, AI infrastructure, and energy storage valued at roughly $3.35 trillion to $3.6 trillion based on SpaceX’s IPO target range and Tesla’s current market capitalization. The two companies are already more intertwined than most people realize. SpaceX bought $697 million worth of Tesla Megapack systems for xAI data centers and $131 million worth of Cybertrucks. Tesla invested $2 billion in xAI, which subsequently merged with SpaceX. Past transactions also include Tesla selling solar equipment and parts to SpaceX, and SpaceX helping with Cybertruck materials.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Musk himself signaled where this was heading in November 2025 when he posted on X, “My companies are, surprisingly in some ways, trending towards convergence.” Tesla and SpaceX announced a joint semiconductor fabrication facility in Austin called Terafab on the Gigafactory Texas campus, covering two advanced chip factories, with one serving Tesla’s AI needs for vehicles and Optimus robots, the other targeting space-based data centers under SpaceX’s infrastructure vision.
Wedbush analyst Dan Ives places the probability of a merger at 80% to 90% with a target completion in the first half of 2027. The mechanics of a deal became possible the moment SpaceX filed its S-1. Legal experts said a merger likely would not spark antitrust issues but would raise concerns among shareholders in each company, with questions around which company would be the parent, how a stock swap would take place, and who determines the appropriate price. Musk holds about 20% of Tesla’s equity but controls 85.1% of SpaceX’s voting power through a super-voting share class, meaning he would largely be negotiating the terms with himself.
Not everyone is convinced the timing is imminent. Traders on Kalshi place only 33% odds that a merger will happen before May 2027. The more immediate concern for Tesla shareholders is whether the SpaceX IPO pulls capital and Musk’s attention away from Tesla before any merger consolidates the upside for both.
What is clear is that the structural groundwork is already being laid. The Terafab announcement, the xAI merger, the shared supply chain, the cross-company balance sheet transactions, and now the IPO all point in the same direction. Whether the merger follows in 2027 or later, the two companies are already operating more like divisions of a single entity than independent competitors.
