THE 15% TRAP

SpaceX IPO Is June 12. Here’s What I’m Seeing in Every Meeting.


5 Takeaways

  • SpaceX announced June 12 as the IPO date. The planning window is now measured in weeks, not months.
  • Most shareholders are using rearview mirror thinking. They are looking at what already happened on a decision that is still ahead.
  • Traditional advisors will tell you to sell down to 15% of net worth. If you had followed that advice the whole way up, you would have a fraction of what you are holding today.
  • The right concentration target is your number, not the rule of thumb. Optimize for sustainable growth first. Layer tax strategy on top.
  • Tax stacks. Salary, RSU vesting, ISO exercises, and share sales all land in the same year. Each event raises your marginal rate for the next one. If you have not modeled the full stack, you have a guess.

I filmed a raw video this weekend at my desk. White t-shirt. Reading glasses. No script. Just the honest version of what I have been seeing in every meeting with SpaceX shareholders for the last four months.

The message in the video is the same as the message in this post.

You still haven’t gotten it yet.

SpaceX announced June 12 as the IPO date. That is days, not months. And the patterns I keep seeing in conversation after conversation tell me that a lot of shareholders are about to walk into this event without a strategy.

Here is what I mean.

The rearview mirror trap

The shareholders I talk to are smart. Senior engineers. Program managers. Technical leads. They built systems that work. They are not unintelligent people.

But when it comes to the equity, most of them are using rearview mirror thinking on a forward-looking decision. They are looking at what already happened. The vest. The 409A. The Slack thread from last quarter. They are reacting to information instead of planning ahead of it.

Pre-IPO equity does not reward reactive planning. The decisions that matter most have to be made before the event, not after it. And the calendar is not waiting.

For the full timeline of what to do and when, the SpaceX IPO Planning Guide for Shareholders breaks it down step by step.

Why the 15% rule is wrong for this moment

Traditional advisors love the rule of thumb. Sell down to 15% of net worth. Diversification is the cardinal rule. Concentration is the cardinal sin.

Here is the problem. If you had followed that rule the whole way up, every time the 409A increased, every time you hit a vesting cliff, every time a tender offer hit, you would not have a fraction of what you are holding right now.

You did not get here by selling. You got here by holding. By staying concentrated through a power-law compounding event.

That does not mean you should stay 100% concentrated. Of course not. Concentration risk is real, especially as the position represents a larger and larger share of your net worth. But the right answer is not “diversify to the rule of thumb.” The right answer is “diversify to your number.”

For some shareholders that target is 50%. For some it is 30%. For some it is 15%. The right number depends on your goals, your time horizon, your risk tolerance, and your view on the company.

If your advisor cannot tell you what your number is and why, that is the conversation to have.

Score your concentration risk and model the diversification path with the SpaceX Concentration Risk Analyzer.

Optimize for growth first. Then optimize for tax.

Here is the sequence that almost nobody is using.

Step one: figure out the right concentration target for your situation. Step two: build the tax strategy that gets you there with the smallest amount of tax leakage.

Most shareholders are doing it backwards. They are starting with tax optimization (which exercise, which AMT bracket, which lot to sell first) and never zoom out to ask the bigger question of what their actual concentration target should be.

Tax optimization on the wrong concentration target is just expensive tax optimization. Get the target right first.

Here is the related trap. Most advisors want to skip you straight to Level 3 (portfolio management) because that is what they sell. But Level 2 (the Builder phase: cash account, tax-advantaged vehicles, concentration reduction) is the foundation you cannot skip. Portfolio management built on a missing foundation is just expensive portfolio management.

For the full Worker to Investor framework as it applies to SpaceX shareholders, the W2I SpaceX page lays out the levels. For the broader three-level system that applies across companies, the framework page walks through Worker, Builder, and Investor in detail.

Tax stacks. Most shareholders have not modeled it.

This is the one that bites every year.

Tax does not add. It stacks.

In a single tax year, you can have salary, RSU vesting (multiple tranches), ISO exercises (with AMT implications), secondary sale proceeds, post-IPO share sales, and any other income from outside SpaceX. Each event raises your marginal rate for the next one.

If you are thinking about tax one decision at a time, you are not seeing the actual bill. The math gets dramatically worse as more events stack on top of each other. The smart move is to model the full year, sequence the events to flatten the marginal rate curve, and identify any offsets that move the needle.

The blog post on SpaceX IPO tax math walks through the actual numbers at $1.75T and $2T valuations. Read that next.

The offsets are real, but quantify the juice

Shareholders ask me about the levers that reduce the tax hit. Married filing jointly. Moving to Nevada or Florida or Texas. Donor-advised funds. Charitable remainder trusts.

These are real strategies. They work. But every one of them comes with friction. Marriage is not a tax strategy on its own. Moving states is not a free trade. A donor-advised fund only makes sense if charitable giving was already part of your plan.

So before you take any of those moves, quantify the juice. What is the actual tax savings, in dollars, for your specific situation? Then quantify the squeeze. What does the change cost you in life, time, and flexibility?

If the juice is worth the squeeze, model it and execute. If it is not, ignore it and focus on the bigger levers.

Find yourself on the map

This is the part that turns the framework from theory into action.

We just published the Worker to Investor SpaceX page, which maps every scenario a shareholder might be in right now to the right level of the framework. If you cannot tell which level you are in, you cannot tell what to do next. So let’s name a few of the scenarios I am seeing most often.

Level 1 (Worker) scenarios. “The blackout is coming and I have not exercised.” “I have ISOs and I do not know what to do.” “My RSU vest hit and the withholding looks wrong.” “The 409A jumped to $527 and I am not sure what it means.” These are time-sensitive and they belong at the top of the priority stack. The action is exercising what you can inside your AMT crossover, modeling the withholding gap before the next vest, and rerunning every calculation at the current $2T-plus valuation. Every model you built six months ago is stale.

Level 2 (Builder) scenarios. “I have $3M in SpaceX equity and $200K in everything else.” “I make $400K and I am only using my 401(k).” “A tender offer opened and I do not know how much to sell.” These are concentration, cash drag, and capital deployment problems. The action is reducing concentration on a schedule that fits your number, maxing every tax-advantaged vehicle available to you (401k, backdoor Roth, HSA, mega backdoor Roth if your plan allows it), and using tender windows to fund the foundation that makes Level 3 possible.

Level 3 (Investor) scenarios. “I sold shares after lockup and now I have $4M sitting in cash.” “I crossed critical mass. Do I keep working?” “I need to start thinking about estate planning and trusts.” “I want liquidity but I do not want to sell and pay capital gains.” These are portfolio construction, preservation, and Investor-level tax problems. Most SpaceX shareholders are not here yet. After June 12, more of you will be.

If you read those scenarios and one of them sounded exactly like your situation, that is the map. The W2I SpaceX page walks each scenario into the right tool and the right next step.

What to do this week

Three things. Not ten.

  1. Pull your full grant summary. Every ISO, every RSU, every vest date, every strike price. One page. If you cannot produce the picture, you have a pile of grants, not a plan.
  2. Run your numbers against the actual numbers, not last month’s estimates. Use the SpaceX ISO Calculator, the SpaceX RSU Calculator, and the SpaceX IPO Diversification Simulator. They are free. No login.
  3. Decide what you are not willing to give back. Put a dollar number on it. Put a time number on it. Then build the plan to protect it.

That is the whole assignment for this week.

Your Equity Built This Far. Strategy Protects What Comes Next.

You earned this position. The hard part is done. You showed up. You performed. You vested. The equity exists because of your work.

But earning the equity and capturing the wealth are two completely different things. The gap between those two things is where the millions live. And right now, with June 12 on the calendar, the gap is closing fast.

When you are ready to talk, hit the Talk to Derek button on the site. You will be talking to me directly. Not a junior advisor. Not a group rate. Just the numbers and a real conversation about your specific situation.

You still have time. You just don’t have much of it.
