Anthropic is planning a $5 to $6 billion employee tender offer at a valuation reported at $350 billion or higher. For many Anthropic employees, this is the first real opportunity to convert paper wealth into actual dollars.

At the same time, reports indicate Anthropic is targeting an IPO as early as October 2026, with Goldman Sachs, JPMorgan, and Morgan Stanley in early discussions.

These two events, happening in close succession, create the most consequential financial planning window most Anthropic employees have ever faced. The decisions you make in the next few months around the tender offer, ISO exercises, and tax planning will compound for years.

The employees who plan now will keep significantly more than those who react after the fact. This guide walks through what you need to know and what you need to do.

The Tender Offer: Your First Real Liquidity Window

The tender offer gives eligible employees the opportunity to sell a portion of their vested equity to outside investors. Reports suggest the company has allocated $5 to $6 billion to the program, though the final amount depends on participation.

Here is why this matters so much. Anthropic is still a private company. You cannot sell shares on the open market. The tender offer may be your only chance to convert equity into cash before the IPO. And if the IPO timeline shifts (which happens), it could be your only liquidity event for a while.

What You Need to Decide

How much to sell. Selling a portion still leaves you with substantial exposure to future upside. If the tender permits selling 10% to 25% of your vested position, you retain the majority of your equity. This is not an exit. It is partial liquidity. The question is: how much cash do you need now, and how much concentration risk are you comfortable carrying into an uncertain IPO timeline?

Which shares to sell. This is where most employees make costly mistakes. If you hold both ISOs and NSOs, the tax treatment is completely different depending on which shares you tender. In most cases, tendering NSO shares first is the better move. NSOs are taxed as ordinary income regardless of when you sell them. ISOs, on the other hand, can qualify for long-term capital gains treatment if you meet the holding requirements (one year from exercise, two years from grant). Selling your ISOs in a tender offer before meeting those requirements turns them into a disqualifying disposition, meaning they get taxed the same as NSOs anyway. You lose the tax advantage entirely. The order matters enormously.

Use tender proceeds to fund ISO exercises. This is one of the highest-leverage moves available to early Anthropic employees. Here is the sequence: tender your NSO shares for cash, use that cash to exercise your ISOs, and start the holding period clock toward qualifying disposition. When a future liquidity event arrives (IPO or next tender), those exercised ISOs can potentially qualify for long-term capital gains treatment instead of ordinary income. The difference between a 23.8% capital gains rate and a 50%+ ordinary income rate in California is substantial. This strategy requires capital and planning, but for employees with low-strike ISOs, the tax savings can be six figures.

The Tax Impact Is Bigger Than You Think

For California-based Anthropic employees, the combined marginal rate on tender proceeds can exceed 50%. Federal income tax at the top bracket (37%), California state tax (13.3%), Medicare (1.45%), and Additional Medicare Tax (0.9%). If your tender proceeds stack on top of your base salary, bonus, and any RSU vesting in the same year, you could be paying more than half of your proceeds in taxes.

Here is what a proactive advisor would be telling you right now: the year you sell matters as much as how much you sell. Coordinating tender participation with your other income sources, ISO exercise timing, and charitable strategies can reduce your effective tax rate significantly. But this planning has to happen before you submit your tender election. Not after.

Understanding Your Anthropic Equity

Anthropic employees hold different types of equity depending on when they joined and their role. The company is transitioning from options-heavy compensation (for earlier employees) to more RSU-heavy packages (for newer hires and refresher grants). Recent grants may be split between options and RSUs, with RSUs making up the larger portion. This means employees at the same company face genuinely different planning challenges. And employees with multiple grants may hold a mix of ISOs, NSOs, and RSUs, each with different strike prices, vesting schedules, and tax treatment. Mapping your full equity inventory is the first step before making any decisions.

Incentive Stock Options (ISOs)

Many early Anthropic employees hold ISOs with low strike prices. The spread between your strike price and the current 409A fair market value may be enormous. As the company’s valuation has climbed, the cost of waiting to exercise has grown with it. Every 409A update that increases the fair market value makes your future exercise more expensive and increases your AMT exposure. It is only going to get more expensive from here.

Here is the critical detail. Exercising ISOs does not trigger regular income tax. But the spread between your strike price and the fair market value IS an AMT preference item. At Anthropic’s current valuations, the AMT bill from exercising ISOs can be hundreds of thousands of dollars.

The strategic response is to batch-exercise ISOs across multiple tax years, staying within your “AMT-free zone” each year. This is the single highest-leverage planning decision for early Anthropic employees. Waiting until the IPO year to exercise concentrates all tax events into your highest-income year. Starting now spreads the impact and can save six figures.

How to fund the exercise. This is the practical question every Anthropic employee asks. You need cash for two things: the exercise cost (strike price times number of shares) and the potential AMT bill. Your options include using tender offer proceeds (sell NSOs first, use the cash to exercise ISOs), taking a securities-based loan against your existing brokerage account (rates are typically SOFR plus 4 to 5%, which may be lower than the expected return on your investments), or pulling cash from a taxable brokerage account. Each has tradeoffs. Non-recourse exercise funding companies exist but often charge 20 to 30% of the stock value at exit, which is extremely expensive. A securities-based loan or using tender proceeds is almost always a better option.

The AMT credit carryforward. Here is something many Anthropic employees do not know: AMT paid on ISO exercises is not gone forever. It becomes a credit you can use against your regular tax in future years. So if you pay $50,000 in AMT this year because of an ISO exercise, you can recover some of that as a credit in future years when your regular tax exceeds your AMT. You will not get it all back in one year. It comes back in increments. But it does come back. Make sure your CPA tracks this carefully because many do not.

Start the qualifying disposition clock now. To qualify for long-term capital gains treatment on ISOs, you must hold the stock for at least one year from exercise date and two years from grant date. The sooner you exercise, the sooner that clock starts. If you wait until six months before the IPO to exercise, you will not meet the holding requirement when the lockup expires and you want to sell. That turns your ISO into a disqualifying disposition, taxed the same as an NSO. You lose the entire tax advantage.

Non-Qualified Stock Options (NSOs)

NSOs are taxed as ordinary income at exercise based on the spread between your strike price and the fair market value. For California-based employees, the combined rate can exceed 50%.

Because NSO exercise income stacks on top of your W-2 salary, tender proceeds, and any RSU vesting, the year you choose to exercise has a direct impact on your total tax bill. Exercising NSOs in the same year you participate in the tender offer can push hundreds of thousands of additional dollars into the highest tax brackets.

Restricted Stock Units (RSUs)

Newer Anthropic employees may hold RSUs. Anthropic RSUs are typically double-trigger: they require both time-based vesting (usually 25% per year over four years) and a qualifying liquidity event (IPO, acquisition, or company-approved tender) before they settle.

If the tender offer qualifies as the second trigger, your vested RSUs would settle at the tender price and the full value is taxed as ordinary income at that point. This can create a massive income spike in a single year.

If the tender does not trigger your RSUs, they remain unvested until the IPO or another qualifying event. Understanding whether your specific grant terms include the tender as a trigger is essential before making any decisions.

The ISO vs. RSU Election

Some Anthropic employees may have the option to choose between ISOs and RSUs for new grants. This is an irreversible decision that depends entirely on your personal financial picture. ISOs offer the potential for long-term capital gains treatment but carry AMT risk and require capital to exercise. RSUs are simpler (no exercise decision, no cash outlay) but are taxed as ordinary income at settlement.

The right choice depends on your liquidity, your risk tolerance, your other income, and your timeline. This is a decision that should be made with professional guidance, not a Slack thread.

Preparing for a Potential IPO in Late 2026

If Anthropic goes public in October 2026 or later, your shares will be locked for 90 to 180 days after the listing. You will owe taxes on vesting events during the lockup while unable to sell. This is the same trap that catches employees at every IPO.

What to Do Now

Build a cash reserve for taxes. Between the tender offer, potential RSU acceleration at IPO, and ISO exercises, you may owe six figures or more in taxes before you can sell public shares. Start building that reserve now.

Model your full-year income across multiple scenarios. What if you participate in the tender AND the IPO happens in the same calendar year? What if the IPO slips to 2027? Each scenario has a different optimal strategy for ISO exercises, NSO timing, and charitable giving.

Design your post-lockup selling plan now. Decide what percentage of your position you will sell in the first 30 days after lockup expires. Write it down. Commit to it before the emotions of a live stock price cloud your judgment.

Consider hedging strategies. Depending on the terms of your lockup and the availability of options markets after IPO, you may be able to use a cashless collar to protect against downside risk during the lockup period.

The Decisions That Will Cost You the Most

Exercising all your ISOs in one year. Batch-exercising across tax years is almost always better. The AMT savings from spreading exercises over 2026 and 2027 can be six figures.

Participating in the tender without modeling the tax impact. Your tender proceeds stack on top of all other income. Without modeling, you may be shocked by the effective tax rate.

Waiting until IPO day to start planning. ISO exercise timing, cash reserves, and selling plans all need to be established months before the IPO. By listing day, most of the best planning windows have closed. The options themselves do not expire, but the opportunity to exercise them tax-efficiently does.

Skipping a tax projection before exercising. Before you exercise any options, pay a CPA to run a tax projection. They will take your current year income, model the exercise, and tell you exactly what your AMT exposure will be. This costs a few hundred dollars and can prevent a six-figure surprise at tax time. Make sure you work with a CPA who understands tech equity, not a generalist who sees ISO exercises once a year.

Making the ISO vs. RSU election without professional advice. This is irreversible and depends on your complete financial picture. A wrong choice can cost tens of thousands over your career at Anthropic.

Ignoring California tax sourcing if you relocate. If you move to a no-income-tax state before the IPO, California may still tax equity that vested while you were a California resident. The sourcing rules are complex and need to be modeled for each grant.

Why This Planning Cannot Wait

The tender offer is happening now. The IPO may be months away. Every week you delay planning is a week of lost opportunity to optimize ISO exercises, build tax reserves, and design a framework for your most consequential financial decisions.
