Anthropic IPO: A Financial Planning Guide for Employees

Published on July 13, 2026

If you’re an Anthropic employee with equity in the company, you may be facing significant financial decisions ahead of the IPO. Anthropic confidentially filed its initial registration paperwork with the U.S. Securities and Exchange Commission on June 1, announcing its intent to go public. None of the details are available yet, and the filing doesn’t guarantee the company will go through with the IPO. But that shouldn’t stop you from making a plan.

If you’ve never gone through an IPO, you may feel overwhelmed by what it means, how much you might gain from it and what you need to do. The key is to take small steps now. Start gathering information, building a team and envisioning your life post-IPO.

First, zoom out

It’s easy to get stuck thinking only about the buy/sell strategy of an IPO. But this is a financial event that, if handled well, could accelerate or meet your most exciting financial goals. Could you buy a house faster? Achieve financial independence earlier? Pay off debt? Send your children to college?

“I think it’s important to use this as an opportunity to get your whole financial picture in order, and not just focus on this,” says Peter McGinley, a certified financial planner (CFP®) with NerdWallet Wealth Partners.

Having a solid, holistic plan can be an anchor over the next several months when waiting and watching feels nerve-wracking. If you’re working with a financial advisor, they’ll walk you through what to do to update or create a financial plan that gives you confidence as the clock ticks down toward the IPO.

Steps to take

Write down two to three concrete financial goals this liquidity could accelerate.
Consider avoiding major purchases or financial commitments until you’ve built a plan.
If you don’t have a financial advisor, start looking for one now, but keep in mind that “financial advisor” is not a regulated title. Look for verifiable credentials such as CFP and verify registration via FINRA’s BrokerCheck site or the SEC’s IAPD database. A good one needs time to understand your full picture before the IPO.

Know what you actually hold

You may have one or more types of equity, including incentive stock options (ISOs), nonqualified stock options (NSOs) or restricted stock units (RSUs). Each type gives you shares in Anthropic, but their mechanics and tax treatment differ. It’s important to know what you hold and to understand how that changes the decisions you’ll need to make before and after an IPO.

RSUs vs. stock options: The basics

Attribute	Restricted stock units (RSUs)	Stock options
What are the typical stages?	Grant, Vesting, Transfer, Sale	Grant, Vesting, Exercise, Sale
What is the value based on?	The market price. Because you don’t pay to acquire the shares, they’ll always have some value, unless the share price of your company goes to $0.	The bargain element — that is, the difference between the strike price and the market value of the shares at the time they’re exercised. Because you pay to acquire the shares, options are valuable when the strike price is lower than the market price.
How are they taxed?	Usually, the market value of the vested shares is taxed as ordinary income. You may also be taxed on any capital gains when you sell.	ISOs: Typically, taxes are deferred until you sell your shares, though you may trigger the alternative minimum tax when you exercise. If you meet certain holding-period requirements when you sell, any profit from the sale may be taxed at the typically lower capital gains tax rate. NSOs: The bargain element is usually taxed as ordinary income. You may owe capital gains tax when you sell.
When are taxes owed?	When the shares vest. This means employees don’t have the ability to time the tax event. You may also owe capital gains tax later if you sell the shares.	When you exercise your options. This means employees have some ability to time the tax event. You may also owe capital gains tax later if you sell the shares.

ISOs: Be prepared for AMT risk

With ISOs, taxes on your shares are usually deferred until you sell. But if your potential windfall is big enough, alternative minimum tax (AMT) may apply in the year you exercise. AMT is a parallel tax system that follows different rates and rules. It’s calculated at the same time as the standard federal income tax, and you’ll pay whichever bill is higher.

The goal of AMT is to make high earners pay at least some income tax, which means you may lose some tax breaks. For example, there is no standard deduction or state and local tax deduction under the AMT system. For ISOs, that also means the IRS treats the difference between the strike price and the fair market value of your shares as income when you exercise your options.

We don’t know yet where Anthropic shares will price if and when it starts trading. But that spread could be very large — especially if you were an early stage hire. (The strike price for your ISOs is typically based on the valuation of the company at the time they’re granted.) In just 14 months, valuations of Anthropic jumped from roughly $61 billion to $965 billion.

Ultimately, you will need to decide when to exercise your options, as well as how much to exercise at once. AMT exposure will play a role in your decision. For example, say you hold ISOs with a $10 strike price.

If you exercise after the IPO, you could have a much larger spread. If the stock opens at $200 after the IPO, it could be $190 per share — or $190,000 on 1,000 shares. That could lead to a substantial tax bill. But you may be able to sell some of your shares to help pay the taxes.
If you exercise before the IPO, the spread may be smaller if it’s based on an independent valuation that is lower than what the stock would trade for publicly. But that requires having the cash to exercise and handle any taxes before you have the ability to sell.

RSUs: Take a look at your withholding

With RSUs, you avoid decisions around when to exercise, and you don’t have to put up any cash to receive your shares. But you may still be in for a surprise tax bill.

The IRS treats RSUs as ordinary income when they vest. RSU vesting typically takes place over a number of years, but if you hold double-trigger RSUs, then another event (often a liquidity event, such as an IPO) also has to occur in order for the RSUs to vest. That means if you hold double-trigger RSUs, you may not have any vested RSUs yet. Also, when you prepare to file your annual tax return, you may notice that the income on your W-2 appears much higher than what was in your paychecks. That may be due to your vested RSUs.

Employers often withhold taxes on vesting RSUs, similar to how they withhold taxes on regular income. This may happen through a “sell to cover” arrangement, in which you elect for a portion of your vested shares to be sold on the vesting date to cover the withholding. You’d receive fewer shares than your original grant promised, but, in theory, you already paid your taxes.

In reality, underwithholding is a common issue. The IRS default tax withholding rate on supplemental income is 22% (37% on any supplemental income above $1 million). But that default rate may not be enough. To avoid surprises, you’ll need to determine what your withholding rate should be, and then make changes before your RSUs vest. Your company’s HR department or equity platform should be able to walk you through the mechanics.

Steps to take

Log into your equity platform and pull your full grant history. For each grant, make a note of the type, grant date, strike price or grant price, vesting schedule and number of vested shares vs. unvested shares.
Ask your equity platform or HR if the company has established a fair market value for the shares before the IPO (a 409A valuation). This can help you model your income per share if you exercise your options before the IPO.
If you have ISOs, calculate the spread on your vested grants (estimated fair market value minus strike price) to get a sense of your AMT exposure. A CPA or financial advisor can help you model this, including how many shares you might be able to exercise before AMT kicks in. Getting this advice before the IPO gives you time to act without urgency.
If you have RSUs, estimate the income from RSUs that vest at the IPO, and then calculate whether the default 22% withholding rate will be enough to cover the tax bill. Check with your equity platform or HR to confirm the withholding rate and method. You may be able to sell to cover. If you think the withholding rate is too low, adjust it before the IPO (or plan to make estimated quarterly tax payments to cover the gap).

Understand what you can do — and when

The IPO may not be the finish line you’re hoping for. You may face certain restrictions around when you can actually sell your shares. The rules are unique to each company, so we won’t know Anthropic’s until its SEC filings become public. But you can still plan for the likely scenario that there will be a significant chunk of time — possibly six months — when the company is public but you can’t sell your shares. Companies use lockup agreements to prevent certain shareholders (including employees) from suddenly flooding the market with shares, which could bring the stock price down.

The lockup period has tax implications you’ll need to incorporate into your plan once details are released. But there’s also an emotional side you should prepare for. Stock prices are volatile, and a post-IPO price pop may not last until you’re free to sell. It’s unrealistic to try to predict what will happen to the company’s stock price, even if you work there, McGinley says. “So we don’t try to predict it. We just try to plan for all scenarios.”

At this stage, you’ll need to determine how much stock you want to keep long-term. Even if you strongly believe in Anthropic’s future, you should be mindful of how much of your net worth and income is tied to a single company. Selling some of your holdings may reduce your concentrated risk.

Steps to take

Understand the liquidity terms. Lockup agreements typically span 180 days, but the terms may differ depending on your role in the company. For example, it may be longer for executives and directors, who likely hold more stock. Additionally, look for a lockup waiver, which may allow some shareholders to sell before the lockup expires. These terms affect when and how many shares enter the market, which can affect the share price and your own plan to sell.
Work with an advisor to model scenarios. You should feel confident that your plan will hold up even if the stock price drops, rises or stays the same between the IPO and the expiration of your lockup period.
Consider whether and how to address concentration risk over time. You may want to evaluate the tradeoffs based on your situation and make a plan for trimming your holdings over time to mitigate the risk.

Plan for future equity grants

These probably aren’t the last Anthropic shares you’re going to get. Your future compensation may include additional equity, which will be easier to sell once the company is public.

McGinley says many clients choose to sell RSUs when they vest. Selling soon after vesting may reduce future capital gains exposure and may help reduce concentration risk. In addition, he says, it helps to think of future equity grants as cash bonuses. If someone handed you the cash today, would you use it to buy Anthropic stock? Often, selling and using the money to diversify into other assets may better align with long-term financial goals.

Steps to take

Build future equity grants into your ongoing financial plan. If you decide to sell shares when they vest, consider using the proceeds to diversify your holdings and meet your other financial goals.
Review your plan annually so you can adjust if your financial situation — or Anthropic’s — changes significantly.

Follow the plan

The beauty of making a plan before an IPO is you get to feel like you’re driving the car instead of riding a roller coaster. You may not know every detail about Anthropic’s big debut yet. And you can’t control price swings once it’s public. But you can know what possibilities the IPO creates for you and what traps it puts in your path.

A potential IPO could happen quickly. Getting started — even just by identifying what you hold and having a first conversation with a tax professional or financial planner — could put you in a strong position before the opening bell.
