Jim Cramer recently told television viewers that they should consider buying SpaceX shares for their kids, a casual statement that glosses over a massive structural reality: SpaceX is private. You cannot simply open a brokerage account, type in a ticker symbol, and purchase a slice of Elon Musk's aerospace behemoth for a minor's custodial account. Yet the televised recommendation touches on a genuine parental anxiety about generational wealth, technological displacement, and missing out on the next technological monopoly.
Retail investors hear a famous pundit mention a company and assume accessibility. That assumption crumbles the moment you try to execute a trade. SpaceX remains closely held, funded by private equity, venture capital, and Musk's own balance sheet. If you want to secure exposure to the commercial space economy for the next generation, you have to look past the CNBC soundbite and examine how private markets actually operate, what the valuation metrics really look like, and why retail access to such assets remains intentionally restricted by securities law.

The Structural Illusion of Private Monopolies
SpaceX dominates global launch services. Starlink commands an unprecedented share of low Earth orbit satellite internet. These facts are undisputed. What is disputed, and rarely addressed by television commentators, is the liquidity wall that separates private titans from ordinary portfolios.
When a company stays private longer, ordinary people are cut off from the early equity appreciation that used to enrich public market participants. Decades ago, companies went public when they achieved moderate scale. Today, tech and aerospace giants linger in the private sector well past valuations of one hundred billion dollars. Additional details regarding the matter are explored by The Wall Street Journal.
SpaceX operates on its own timeline. It does not answer to quarterly earnings calls from jittery institutional holders in the same way a public corporation must. This grants Musk immense strategic freedom to pursue capital-intensive, multi-decade gambits like the Starship program without facing an immediate stock collapse over short-term missed revenue targets.
For parents hoping to build a nest egg, this freedom is a double-edged sword. You get stability from short-term market noise, but you also get zero liquidity. You cannot sell shares to pay for college tuition next fall. Your capital is locked behind a velvet rope reserved for institutional funds, accredited investors, and sovereign wealth entities.
Decoding the Valuation Game
Talk of buying SpaceX for anyone requires confronting astronomical valuation figures. Private funding rounds routinely price the company at staggering levels, often rivaling or exceeding the market caps of venerable public defense and aerospace contractors.
How do private valuations work when there is no daily public market to price the asset? They rely on periodic tender offers and private placements. Employees and early backers occasionally sell blocks of shares to institutional buyers like fidelity or venture firms, establishing a benchmark price.
Consider a hypothetical family trying to mimic institutional access. Suppose an investor attempts to use a special purpose vehicle or a secondary market platform that promises access to pre-initial public offering shares. These vehicles often carry steep administrative fees, high investment minimums, and strict accreditation requirements. The Securities and Exchange Commission guards these boundaries fiercely. They exist to protect everyday people from illiquid, high-risk assets, but they also lock working-class families out of the wealth generated by generational monopolies.
If you are an accredited investor with a high net worth, you might gain entry through specialized secondary funds. Even then, the management fees can erode returns, and the holding period can span a decade or more. For a child born today, that investment might finally become liquid by the time they finish university, assuming the company executes a clean transition to public markets.
The Public Alternatives and Proxy Plays
Since you cannot buy SpaceX directly, how do you capture the commercial space boom for a child's portfolio? You look at public proxies. The space economy is not a monolith; it is an ecosystem of component manufacturers, satellite operators, defense contractors, and material science firms.
Defense Contractors and Legacy Aerospace
Companies like Lockheed Martin, Northrop Grumman, and Boeing build hardware that intersects with government space budgets. They pay dividends, offer steady cash flows, and trade on major exchanges. They do not possess the hyper-growth narrative of SpaceX, nor do they carry the same valuation risk. They are defensive anchors.
Pure-Play Public Space Stocks
A handful of smaller satellite manufacturers, launch startups, and space tourism companies trade publicly. Most of them struggle with profitability. They burn through cash at an alarming rate, fighting for survival in the shadow of SpaceX's cost-per-launch dominance. Investing in these smaller public entities carries severe risk. Many are speculative vehicles that experience wild volatility based on a single successful or failed rocket launch.
Broad Technological Exposure
Sometimes the best proxy for a dominant private enterprise is the broader technological infrastructure that supports it. Semiconductor manufacturers, advanced materials producers, and cloud computing giants provide the underlying muscle for modern aerospace engineering. Buying shares in a diversified technology index fund for a child offers exposure to the broader sweep of innovation without the catastrophic single-stock risk of a failing micro-cap space stock.
The Reality of Custodial Accounts and Long Horizons
Setting up a custodial account, whether a Uniform Gifts to Minors Act account or a Uniform Transfers to Minors Act account, is a straightforward administrative task. Funding it with assets that can actually compound over an eighteen-year horizon requires discipline.
If Cramer's advice contains a kernel of wisdom, it is the focus on long-term horizon thinking. Children have time on their side. They can afford volatility. They can absorb a bear market and watch an asset class mature.
However, channeling that time horizon toward an unavailable asset like SpaceX misses the operational reality of personal finance. A parent cannot buy what is not for sale. Chasing complex, high-fee secondary market structures to grab a fractional piece of a private rocket company often introduces more friction and risk than the potential alpha justifies.
Instead, building a durable portfolio for a minor means accepting the boring mechanics of index investing, dollar-cost averaging, and selecting publicly traded assets with transparent financials. The romance of space exploration captivates the imagination, but brokerage statements care only about cash flow, valuation multiples, and execution.
The commercial space race will reshape global communications, defense, and logistics over the next generation. Participating in that economic shift does not require owning the market leader through opaque channels. It requires disciplined capital allocation, a clear-eyed view of market access rules, and the patience to let public equities compound while private giants play their own high-stakes game behind closed doors.
