Space Exploration Technologies (NASDAQ: SPCX), AMD (NASDAQ: AMD), and Palantir Technologies (NASDAQ: PLTR) may seem like an odd grouping of companies. But I have a good reason to consider them together: They're all incredibly overvalued.
While that may sound like a shocking statement, after digging into each stock, that's the reality, and investors sitting on them may want to consider swapping them out of their portfolios for some more reasonably valued counterparts in their industries.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue »
So, just how pricey are they? Let's take a look.
Although SpaceX just went public a few weeks ago, I think it's one of the most overvalued stocks on the market. But that's only if you value the company based on what it has already done.
The majority of SpaceX investors are buying into the stock because of what it could achieve under Elon Musk's leadership. That's a fair investment thesis, and it's what has allowed Tesla to remain one of the largest companies in the world despite its business struggles over the past few quarters. If that's your angle, I'm not going to argue, but it doesn't alter the fact that SpaceX's business as it stands now does not justify the company's valuation.
SpaceX hasn't reported earnings results as a public company yet, so the only information investors have to go on is from its IPO presentation. According to that, in 2025, SpaceX generated $18.7 billion in revenue and reported negative net income. So if we value the company using 2025 sales, that would price SpaceX at 92 times sales.
Even if SpaceX could snap its fingers and become instantly profitable with a 45% profit margin (its stated long-term goal), that would value the stock at 204 times earnings. That's an incredibly expensive stock, and with 2025 revenue growth coming in at only 33%, those numbers don't jibe.
That's not to say SpaceX cannot overcome this with future growth, but even then, a lot of hoped-for growth is already priced into the stock, so I'm avoiding it.
AMD stock has risen by about 150% so far in 2026. While some of that gain was earned, the rest of it is a real head-scratcher.
AMD is constantly compared to Nvidia, as these two compete against each other in many product lines, but the most important arena for both right now is the data center market. Nvidia's data center division is far larger and growing much faster than AMD's, which makes it odd that AMD is now valued at such a premium to Nvidia.
Four leading AI models discuss this article
"High multiples are justified only if 40%+ sustained growth materializes; the article underweights execution risk and TAM expansion while over-relying on trailing or static 2025 figures."
The article claims SpaceX (SPCX), AMD, and PLTR are wildly overvalued—92x 2025 sales for SpaceX despite negative earnings and only 33% growth, plus AMD trading at a premium to Nvidia despite lagging data-center momentum. This is directionally fair on multiples: SPCX's implied 204x earnings even at a hypothetical 45% margin looks extreme. However, the piece glosses over SpaceX's Starlink subscriber ramp (already >4M users), reusable-rocket cost curve, and multi-year NASA/DoD backlog that could drive 50%+ CAGR. AMD's 150% YTD move in 2026 reflects MI300/MI350 AI GPU traction and potential share gains if Nvidia supply remains constrained. Missing context: growth optionality and margin expansion trajectories matter more than static multiples when TAMs are expanding 40-60% annually.
The strongest case against my skepticism is that these names are priced for perfection precisely because their addressable markets (satellite broadband, AI accelerators, defense software) are still in early innings; if execution hits, current multiples compress rapidly via 40%+ revenue CAGR, rendering today's 'overvalued' label irrelevant within 24 months.
"The article fails to distinguish between speculative hype and the structural strategic value these companies provide to the AI and aerospace supply chains."
The article’s premise is fundamentally flawed, most notably by claiming SpaceX is a public company; SpaceX remains private, rendering the '92x sales' valuation analysis speculative at best and factually incorrect at worst. Regarding AMD, labeling it 'overvalued' relative to Nvidia ignores the market's appetite for a viable second-source supplier in AI silicon, which is a strategic necessity for hyperscalers. Palantir, while trading at a high forward P/E, is successfully pivoting from government consulting to high-margin commercial software, which warrants a premium. Investors should ignore the 'overvalued' blanket statement and instead focus on the margin expansion and total addressable market (TAM) capture rates for each firm.
If we enter a period of prolonged high interest rates, the 'growth-at-any-cost' valuation multiples assigned to these companies will likely undergo a violent, justified contraction.
"The article correctly identifies high multiples but fails to establish whether growth rates justify them—a critical omission that undermines the overvaluation thesis."
This article makes a valuation argument but conflates two distinct problems. SpaceX at 92x sales is expensive—agreed—but the author then admits the thesis is about future growth under Musk, which is precisely what justifies high multiples for early-stage, capital-intensive infrastructure plays. That's not a flaw; it's the business model. AMD's 150% YTD gain needs context: vs. what baseline? If Nvidia is up 200%, AMD underperformed despite better valuations. The real issue the article dodges: are these companies' growth rates sustainable enough to justify current prices, or are they priced for perfection? The article asserts overvaluation without modeling breakeven scenarios.
If SpaceX achieves even 20% of its stated margin targets while maintaining 25%+ revenue CAGR, a 92x sales multiple on a 2025 base becomes defensible within 3-5 years—the article's 'negative earnings' snapshot ignores the trajectory entirely.
"The 'overvalued' label is overly simplistic; growth optionality and strategic tailwinds may justify high multiples, given credible revenue ramps and AI/space secular demand."
The article rests on shaky ground: SpaceX public status/ticker is dubious; 2025 revenue, negative net income, and 92x sales imply a stretched base case. SpaceX, if public, would be priced for enormous future cash flows from Starlink, human spaceflight, and defense, so some premium may be justified despite current losses. AMD being described as valued at a premium to Nvidia is questionable in most periods— Nvidia still leads AI compute and data center growth; Palantir's valuation hinges on government vs. commercial mix and profitability trajectory, not just hype. The missing context includes capex needs, regulatory risk, and AI-cycle sensitivity.
The market could be pricing in significant optionality (Starlink monetization, defense budgets, AI compute demand). If those bets hit, the multiples here make sense; a negative view today could prove shortsighted.
"Starlink ARPU erosion in emerging markets could invalidate high multiples even with strong subscriber growth."
Gemini's claim that SpaceX is not public is correct, but it sidesteps the core valuation debate: private rounds still embed 90x+ sales multiples via secondary markets. The real gap is nobody quantified Starlink's ARPU compression risk as subscriber mix shifts to lower-margin emerging markets. If global broadband pricing falls 30-40% by 2027, even 50% CAGR won't justify current implied EV.
"SpaceX's valuation is anchored by launch dominance, not just Starlink's ARPU, making Starship's operational success the primary risk factor."
Grok, your focus on ARPU compression is the only tangible risk mentioned, but you’re ignoring the moat. SpaceX isn't just a broadband provider; it’s the only entity with a reliable heavy-lift launch cadence. Even if Starlink pricing drops, the launch business creates a floor for valuation that software-only firms lack. Gemini and ChatGPT are right to flag the private status, but the real danger is the 'priced for perfection' trap: any delay in Starship's operational reliability tanks the entire thesis.
"SpaceX's valuation depends on at least one of two businesses (launch or Starlink) maintaining pricing power; current multiples assume both do."
Gemini's launch-business moat argument is stronger than the Starlink-only thesis, but it inverts the risk. Heavy-lift cadence only matters if SpaceX captures pricing power—which erodes if competitors (Blue Origin, Rocket Lab) mature. The real question: does launch margin sustain valuation if Starlink commoditizes? Nobody's modeled a scenario where both businesses face margin compression simultaneously. That's the 'priced for perfection' trap Gemini mentioned, but it cuts deeper than Starship delays.
"Valuation should hinge on near-term cash-generation milestones and funding dynamics, not only ARPU risk, because capex burn and contract timing could trigger rapid multiple compression."
Grok flags ARPU compression as the real risk; I’d push further: the valuation ignores funding cadence and capex burn required to scale SpaceX’s Starlink and launch stack. Even with improving margins, DoD/NASA backlog timing and Starship certification create stiff cash-flow cliffs. If cash burn accelerates or revenue visibility slips by 12–18 months, a 92x sales multiple collapses far faster than any upside from ARPU. Optionality isn't a cushion without near-term cash-gen milestones.
The panelists agreed that SpaceX, AMD, and PLTR are overvalued based on current metrics but have growth potential. They highlighted risks such as ARPU compression, competition, and cash flow cliffs.
