Your SpaceX Equity Built Real Wealth. Let's Make Sure It Lasts.
Vested shares, ISOs, RSUs, tender offers; more of your net worth sits in one company every year. The same company that signs your paycheck. Amplius helps SpaceX shareholders turn concentrated equity into a diversified, tax-smart plan, on your timeline and on your terms.
Nobody Decides to Be Over-Concentrated. It Just Happens.
You didn't set out to put most of your wealth in one stock. It accumulated, RSUs settle, ISO spreads widen as the 409A climbs. Tender offers come and go, and the position keeps growing. One day you run the numbers and 70–90% of your net worth is SpaceX, alongside your salary, your benefits, and your career.
That isn't conviction. That's exposure.
Holding longer can feel like the smart move. The story is strong, the trajectory has been remarkable, and selling feels like leaving money on the table. But a diversified plan isn't a bet against SpaceX; it's a decision to preserve the wealth you've already earned.
The math is unforgiving: a 50% decline requires a 100% gain just to break even. If 80% of your net worth is one stock and it falls 40%, your total net worth drops 32%. Research from J.P. Morgan Asset Management has found that a significant share of individual stocks (on the order of 40%) suffer catastrophic declines they never fully recover from, and the figure runs higher for technology companies. Private markets can mask volatility; public markets don't.
Three ways concentration gradually raises the stakes:
The asymmetry of loss
Gains and losses aren't symmetrical. Down 50% needs up 100%. A diversified portfolio doesn't just grow; it survives the cycles that let compounding work.
The double-dependency trap
Your paycheck, benefits, equity, and career all trace back to one company. A single change at SpaceX can touch all of them at once.
The liquidity illusion
Pre-IPO shares aren't cash. You can't sell on a bad day. Tender windows are periodic and can be cut back. Your net worth on paper may not be your net worth when you need it.

7 Ways to Reduce Risk Without a Reactive Sell-Off
Diversifying a concentrated position is rarely one move. It's a coordinated set of them, sequenced across tax years to keep more of what you've built. These are the strategies in the Amplius Concentrated Stock Playbook. The right mix depends entirely on your basis, your timeline, and your goals.
Equity Collar
A collar wraps your stock in a protective band: buy a put to set a floor, sell a call to help pay for it. Often structured at low or zero net cost. You keep ownership while capping the worst case. The trade-off: Your upside is capped too.
Long/Short Tax-Loss Harvesting
A long/short portfolio tracks the market while systematically harvesting losses. Those losses can offset the gains from selling concentrated stock. No multi-year lockup, you own the securities directly, and first-year harvested losses can be a noteworthy share of invested capital.
Exchange Fund Replication (EFR)
EFR uses options to cut single-stock risk substantially and replace it with broad-market exposure—without a taxable event today. Daily liquidity, standard 1099 reporting, no qualified-purchaser requirement, and no seven-year lockup.
Traditional Exchange Funds
Contribute your shares into a pooled partnership and receive a diversified basket in return (no tax at contribution). The classic tool, but harder to use now: strict eligibility, a seven-year lockup, and higher fees.
Qualified Opportunity Zones (QOZ)
Reinvest capital gains into opportunity zone real estate for a "triple" benefit: defer the original gain, step-up basis over time, and (if held 10+ years) pay no tax on the QOZ investment's own growth. Made permanent under recent legislation.
Covered Call
Sell a call above today's price and collect cash now. You're effectively paid to set a limit order at a price you'd be glad to sell at. The trade-off: Upside above the strike goes to the buyer.
Philanthropic Planning
If you're already charitably inclined, donating appreciated stock can beat donating cash. A donor-advised fund lets you "bunch" deductions in a high-income year; a charitable remainder trust can diversify inside the trust and pay you an income stream. Capital gains on donated shares may be avoided entirely.
What Coordinated Planning Can Look Like
Hypothetical: $10M in SpaceX stock, $100K cost basis, 23.8% federal rate on long-term gains.
Estimated tax bill from selling $6M of stock outright.
Retain $3.75M (hold, collar, and EFR) and address $6.25M through a coordinated mix: long/short tax-loss harvesting, a qualified opportunity zone, an exchange fund, and a donor-advised fund.
About a 56% reduction. The collar and EFR reduce SpaceX risk further with no current tax.

Two Kinds of Equity. Two Very Different Tax Stories.
ISOs and RSUs both build wealth, and each carries its own decisions, deadlines, and tax treatment. Getting them right is where a lot of value is won or lost.
ISOs — leverage, with a tax catch
ISOs give you the right to buy shares at a fixed strike price. The leverage is real, and so is the complexity. Exercising and holding can trigger the alternative minimum tax (AMT) on the "spread" between your strike and the current 409A value—even though you haven't sold a thing. Exercise early enough and you start the clock toward long-term capital gains treatment. Wait too long, and a rising 409A can make exercising prohibitively expensive; and a departure usually starts a tight 90-day window to act.
The art is exercising enough each year to make progress without an outsized AMT surprise. That's what the calculator below estimates.
RSUs — simpler, with one trap
RSUs are more straightforward, with one catch to plan around. They're taxed as ordinary income on their full value when they settle. For a pre-IPO company, that's often "double-trigger"; settlement waits for a liquidity event. When it lands, it can be large, and standard payroll withholding (frequently 22%) routinely falls short of what a high earner actually owes. The gap becomes an April surprise. A "sell-on-vest" default and a withholding check keep that from happening.
ISO Exercise & AMT Estimator
Estimate the cash to exercise and the potential AMT impact of exercising and holding.
A rough, educational estimate using 2025 federal figures and a simplified AMT calculation. It ignores state tax, other AMT adjustments, and credits. Your actual result depends on your full return, so confirm with your CPA before exercising.
RSU Tax Estimator
Estimate the tax due when RSUs settle—and the gap typical withholding can leave.
A rough, educational estimate using 2025 federal figures. Actual tax depends on your full return, your state, and your employer's withholding, so confirm with your CPA.
A Clear Path From Concentrated to Confident
Concentrated-stock planning works best when tax strategy, risk management, and investment design are coordinated, then implemented with discipline. Here's how that runs at Amplius.
Map your exposure
We quantify the real number, vested and unvested equity, ISOs, RSUs, and how it all sits against the rest of your financial life. Most people are more concentrated than they think.
Set your target
We define the point where your diversified portfolio can sustain your life without depending on any single stock. That target turns "Should I sell?" into "Here's the plan."
Build the tax-smart path
We sequence sales, exercises, hedges, and gifts across multiple tax years (using the playbook strategies that fit your basis and timeline) to keep more of what you've built.
Diversify and deploy
Proceeds move into a diversified portfolio designed to grow, weather cycles, and eventually produce income. Concentrated equity becomes a durable, independent asset base.
As an independent fiduciary firm, Amplius is paid to advise, not sell you a product. Every recommendation answers one question: Is this right for you?

A short, no-pressure conversation is the fastest way to find out. We'll look at your actual position, talk through the tax-aware paths open to you, and outline what to consider now versus later. No obligation, no jargon.
