Everyone is talking about Space Exploration Technologies (NASDAQ: SPCX), commonly known as SpaceX. With Elon Musk at its helm, it gets a lot of attention. That's part of why it easily raised $86 billion in its historic initial public offering, which was oversubscribed by more than four times.
But there's plenty of risk in owning SpaceX stock. The company is already doing great things, but that doesn't automatically make it a great investment. It's astronomically expensive and spending like money is going out of style; the fundamentals should always be of prime importance to investors.

I may want to revisit SpaceX later, when it's cheaper and looking in better financial shape. But right now, MercadoLibre (NASDAQ: MELI) and On Holding (NYSE: ONON) look like much better growth stocks. Here's why.
MercadoLibre is growing faster than SpaceX, and it's been in high-growth mode for a long time. Management recently noted that it's growing at the rate of a start-up, even though it's already several decades old. Revenue increased 49% year over year in the 2026 first quarter. At this point, it's also the leader in its industry and region, and it's profitable, something SpaceX is missing today.
Growth at MercadoLibre is visible everywhere. Unique active buyers increased 26% year over year on the e-commerce platform in the first quarter, while fintech monthly active users rose 29%. Total payment volume increased 50%, while gross merchandise volume was up 42%.
However, the company still has a massive long-term opportunity. Despite MercadoLibre's years of high growth, its markets remain underpenetrated in e-commerce and fintech, and it continues to improve its value proposition to attract more people to its platform. It has lowered the free shipping threshold in Brazil, leading to many positive results, such as record new additions in the first quarter. It plans to replicate this success across more of its markets as well.
Finally, MercadoLibre's stock has dropped this year due to pressure on the bottom line. The company is expanding to capture market share and strengthen its foundation for future growth, and it's also attracting more people to its credit products, which often carry higher risk until they're established partners. These things are hurting it in the short run, but they create the opportunity for higher growth.
At the lower price, MercadoLibre stock trades at only 43 times trailing-12-month earnings, or near its 10-year low. Compared with SpaceX's 105 price-to-sales ratio, MercadoLibre looks like a much better buy.
On is challenging the leading activewear companies with its premium line of products that are gaining loyal fans. These fans are affluent and resilient and have more money to spend in the inflationary environment, driving robust performance.
In the 2026 first quarter, sales increased 26% year over year (currency-neutral), across both wholesale and direct-to-consumer channels. Since it has a high full-priced sales rate, it has strong margins. Gross margin improved from 59.9% to 64.2%, while profit margin widened from 7.8% to 12.4%.
Said CEO Caspar Coppetti about sustaining the premium brand through full price, "Our results represent this strategy, the kind that builds the brand for years and decades to come."
On is still rolling out and building its brand in many parts of the world. Even in the U.S., where it's fairly well-established, it still has low brand penetration, reaching 30% for the first time in the first quarter.
It's also attracting more younger customers, with its largest-ever increase in the share of 18-to-24-year-olds in its direct-to-consumer customer base in the first quarter. In the annual Piper Sandler Taking Stock With Teens survey, an industry report on retail and brand trends among younger shoppers, On ranked fourth in footwear, indicating a higher market share among buyers.
On trades at only 39 times trailing-12-month earnings, and it looks like a bargain at that price.

Four leading AI models discuss this article
"SpaceX is not a public, cash-flow-driven stock, so using it to frame MELI/ONON as clearly better growth bets overlooks private-market risk and potential IPO mispricings."
Strongest counter: the piece conflates a private SpaceX with public-growth stocks. SpaceX isn’t freely traded; the '$86B IPO oversubscribed' claim and the SPCX ticker look dubious, turning the SpaceX case into hype rather than fundamentals. Even if SpaceX were public, profitability would be uncertain and burn-heavy, so valuation would hinge on future cash flows the article glosses over. MELI/ONON risks—credit losses, LatAm volatility, inflation—are underplayed, and the piece omits On’s brand durability and potential competitive pressure. The article also ignores macro headwinds that could sap e-commerce and premium-brand demand in the next few quarters.
SpaceX, if/when public, could unlock enormous upside through Starlink and launch services, so the skeptics may be premature. The promise of an IPO could still re-rate the stock far higher than MELI/ONON on growth prospects regardless of current profitability.
"The article conflates growth-stage consumer retail with infrastructure-heavy aerospace, failing to account for the specific credit risks inherent in MercadoLibre's fintech expansion."
The article’s premise is fundamentally flawed because it compares a private, capital-intensive aerospace firm (SpaceX) to a mature e-commerce platform (MELI) and a premium consumer discretionary brand (ONON) using mismatched metrics. The author cites a '105 price-to-sales ratio' for SpaceX, which is a speculative valuation metric that ignores the massive recurring revenue moat from Starlink. While MELI’s 43x P/E is historically attractive, it ignores the mounting credit risk in its fintech arm as it moves down-market. Meanwhile, ONON’s 39x P/E assumes it will maintain its 'premium' status without succumbing to the inevitable brand dilution that plagues athletic footwear as it scales beyond the affluent early-adopter cohort.
If SpaceX achieves its launch cadence targets and Starlink reaches global scale, its valuation may not be 'astronomically expensive' but rather a bargain compared to the long-term disruption of the global telecommunications and logistics markets.
"Lower P/E multiples don't make MELI and ONON better investments than SpaceX; they reflect different growth stages and risk profiles, not obvious mispricing."
This article conflates valuation cheapness with investment quality. Yes, MELI trades at 43x P/E versus SpaceX's 105x P/S—but that comparison is meaningless without context. MELI's 49% YoY revenue growth is real, but the article glosses over why margins are under pressure: aggressive credit expansion into riskier segments. On Holding's 64% gross margin is impressive, but 39x trailing P/E on 26% growth implies the market is already pricing in sustained premium positioning. Neither stock is obviously cheaper than SpaceX on a risk-adjusted basis; they're just different risk profiles. The article also ignores macro headwinds: MELI is heavily exposed to Latin American currency volatility and credit cycles, while On faces intensifying competition from Nike/Adidas in premium athletic wear.
MELI's underpenetrated markets and fintech TAM expansion could justify premium multiples for years, and On's brand momentum among Gen-Z is genuinely differentiated—the article may understate their durability.
"MELI and ONON valuations at 39-43x TTM earnings embed aggressive growth assumptions that overlook execution and competitive risks the article downplays."
The article positions MELI and ONON as superior growth plays to SpaceX by citing MELI's 49% revenue growth, 26-29% user gains, and 43x TTM earnings alongside ONON's 26% sales rise and margin expansion to 12.4%. Yet both still trade at premium multiples for their sectors, with MELI pushing into higher-risk credit and ONON dependent on sustained full-price premium positioning amid athletic apparel competition. The SpaceX 105x P/S benchmark is speculative given its private status and the article's own admission of heavy spending. Broader macro sensitivity in Latin American e-commerce and teen-driven footwear trends remains unaddressed.
MELI's long runway in underpenetrated markets and ONON's accelerating DTC share among 18-24 year olds could justify sustained multiples if execution holds, making the relative-value case stronger than the risks imply.
"Starlink capex/regulatory risk undermines the 'bargain' SpaceX thesis without proven near-term cash flow."
Gemini, your push that SpaceX could be a bargain if Starlink scales assumes near-term recurring cash flow that remains far from proven. The real risk you downplay is satellite capex burn and regulatory/geopolitical headwinds that could delay any FCF upside for years. A lofty P/S can compress quickly if launches slow or subsidies wobble. Until SpaceX shows sustained profitability and predictable cash flow, the 'bargain' case is speculative, not a conviction.
"The market is conflating synthetic proxies for SpaceX with actual equity, while ignoring that MELI's fintech margins are highly sensitive to LatAm interest rate cycles."
Gemini and ChatGPT are debating SpaceX's future cash flows, but both are ignoring the immediate capital structure risk: the 'SPCX' ticker mentioned is a synthetic derivative, not equity. Retail investors buying this are chasing a phantom valuation that doesn't reflect SpaceX's actual cap table. Meanwhile, everyone is ignoring that MELI’s fintech expansion is essentially a bet on high-interest rate environments in LatAm; if those central banks pivot to aggressive easing, MELI’s net interest margin collapses.
"MELI's credit risk is more quantifiable and immediate than SpaceX's regulatory delays, yet the panel treats it as secondary."
ChatGPT's SpaceX skepticism assumes regulatory/geopolitical delays are probable, not tail risks. But Starlink already has 6M+ subscribers generating recurring revenue; the burn question is timing, not existence. More pressing: Claude and Grok both flag MELI's credit expansion into riskier segments without quantifying the actual loss rate or comparing it to historical LatAm fintech defaults. If MELI's credit losses spike 200bps above guidance, the 43x P/E evaporates faster than SpaceX's valuation could compress.
"MELI's fintech reporting lags create parallel opacity risk to SPCX that nobody quantified."
Gemini correctly flags SPCX as a derivative trap for retail, but this same valuation opacity applies directly to MELI's fintech expansion where loan performance data lags U.S. standards. If Brazilian or Argentine regulators demand faster NPL disclosure, the 43x P/E compresses before Starlink's capex timeline even matters. Claude's loss-rate ask is useful but incomplete without that regulatory trigger.
The panel is largely bearish on the given article, citing mismatched metrics, speculative valuations, and overlooked risks for SpaceX, MELI, and ONON. They agree that the article glosses over crucial fundamentals and ignores macro headwinds.
No clear consensus on a single biggest opportunity flagged.
The single biggest risk flagged is the speculative nature of SpaceX's valuation and the potential for rapid compression if launches slow or subsidies wobble, as well as MELI's exposure to high-interest rate environments and potential credit loss spikes.
