The SpaceX IPO is one of the most anticipated public market events in years. Millions of Americans are preparing to buy shares for the first time, excited to finally own a piece of one of the most valuable private companies ever built.

What most of them do not know is that some investors were already in. Years ago. At a fraction of today’s valuation. Inside a retirement account.

And the structure they used to do it is still available today.

How Private Market Investing Actually Works

Before a company like SpaceX goes public, it spends years, sometimes decades, growing in the private markets. During that time, its value compounds. Early investors who got in at low valuations generate returns that can be 10x, 50x, or even 100x by the time an IPO arrives.

By the time a company files an S-1 and sets an IPO date, the most significant growth phase is often already behind it. Retail investors buying on opening day are entering at a valuation that already reflects years of private market appreciation.

This is not unique to SpaceX. It is how the modern capital markets work. Companies stay private longer because private capital is abundant and there is no pressure to go public early. The result is that the most valuable phase of a company’s growth happens entirely outside the reach of most individual investors.

Or so most people assume.

What the IRS Has Always Allowed

Here is something most Americans have never been told: the IRS has never prohibited a retirement account from investing in private company stock.

IRC Section 408, which governs IRAs, identifies a short list of prohibited holdings: life insurance, collectibles, and S-corporation stock. Everything else is permitted. Private equity, pre-IPO shares, venture capital fund interests. All of it has always been legal inside an IRA.

The reason most investors did not know this comes down to the platforms they use. Traditional brokerages and custodians, the Fidelitys and Schwabs of the world, do not support private investments. They cannot charge management fees on a private company share the way they can on a mutual fund or ETF. When capital moves into a private company, it leaves their fee-generating ecosystem. So they built platforms that do not support it, and most investors assumed that meant it was not allowed.

It was always allowed. The limitation was institutional, not legal.

How Investors Used Self-Directed IRAs to Access Private SpaceX Equity

A Self-Directed IRA operates under the same IRS rules as a traditional IRA but is not restricted to the investment menu of a brokerage platform. It allows the account holder to invest in virtually any asset the IRS does not explicitly prohibit, including private company stock.

In the years before the SpaceX S-1 filing, investors who knew about Self-Directed IRAs were able to access private SpaceX equity through secondary market platforms, tender offers, and private funds with SpaceX allocations. Every dollar of appreciation that occurred inside the IRA wrapper grew either tax-deferred or, in the case of a Self-Directed Roth IRA, completely tax-free.

For those holding private SpaceX shares inside a Self-Directed Roth IRA, the outcome is particularly significant. Once the account has been open for five years and the account holder is past age 59½, all distributions are 100% tax-free. Not tax-deferred. The IRS has no claim on any of the growth.

This is the same structure that has produced some remarkable outcomes for Self-Directed IRA investors over the years. Investors who used Self-Directed Roth IRAs to buy Bitcoin early or invest in private startups at low valuations have in some cases turned modest initial investments into life-changing sums, entirely tax-free.

SpaceX is simply the most prominent recent example of the same opportunity.

The Opportunity Going Forward

The SpaceX IPO will give any standard retirement account the ability to buy shares at the public market price. That is a meaningful development for investors who want exposure to the company going forward.

But SpaceX is not the only private company with significant growth potential still ahead of it. There are thousands of private businesses across real estate, technology, energy, and other sectors where investors with the right structure can participate before a liquidity event.

The investors who missed the private phase of SpaceX do not have to miss the next one. The same Self-Directed IRA structure that allowed early SpaceX investors to participate is still available and still works exactly the same way. The legal framework has not changed. The opportunity has not gone away. What has changed is that more Americans are becoming aware that it exists.

This is not investment advice. Whether any specific private company represents an appropriate investment depends entirely on an individual’s financial situation, risk tolerance, investment objectives, and other factors. What a Self-Directed IRA provides is access, not a recommendation. The investment decisions remain entirely with the account holder.

Why IRA Financial

Most retirement account custodians do not support private investments. They are built around publicly traded securities and have no infrastructure for holding, valuing, or processing alternative assets.

IRA Financial is one of the few Self-Directed IRA custodians in the country with the expertise and operational infrastructure to support private market investments, including pre-IPO equity, private funds, real estate, cryptocurrency, private lending, and more.

Since 2010, IRA Financial has helped more than 30,000 clients invest over $7 billion in alternative assets inside tax-advantaged retirement accounts. Our team includes in-house tax attorneys and ERISA specialists who review investment structures, evaluate tax implications, and help clients understand exactly what they are doing before they commit.

The investors who accessed private SpaceX equity through a Self-Directed IRA did not do it alone. They worked with a custodian that knew how to make it happen cleanly and compliantly.

If you want to understand how a Self-Directed IRA could expand your investment options, our team is available for a free consultation. There is no obligation and no pressure. Just an honest conversation about what is possible inside a retirement account and whether it makes sense for your situation.

The Bottom Line

The SpaceX IPO is a landmark moment for retail investors. It is also a reminder that the most significant wealth-building opportunities often happen before the public ever gets access.

The legal framework to participate in those opportunities has always been available to ordinary Americans. A Self-Directed IRA does not require a hedge fund budget or Wall Street connections. It requires knowing the structure exists and working with a custodian who knows how to use it.

The next SpaceX is already out there somewhere, growing in the private markets. The question is whether you will be in a position to participate before it goes public.
