For Anthropic employees
Reports suggest Anthropic may be preparing for a public listing. That changes the financial planning conversation.
In June 2026, reports indicated that Anthropic filed confidential paperwork that may relate to a potential initial public offering. If the company eventually goes public, shares that are currently illiquid could become tradable on a public exchange. For Anthropic employees getting married, this is a meaningful moment to get clear on how equity is treated.
Flat fee of $5,000 per couple. No payment to get started.
Why timing matters for Anthropic employees
While the company remains private, equity has no public market price. That makes this window particularly relevant for financial planning. A prenup established now can address your equity while valuation is still determined by internal metrics and funding rounds rather than daily market fluctuations.
This is not about predicting outcomes. It is about having clarity in place before the financial picture becomes significantly more complex.
What changes with a public listing
How equity looks different before and after shares become publicly traded
While private
Your shares have no public market price
If publicly traded
Shares may trade on a public exchange with a daily market price
Once shares become publicly traded, there is a widely available market price rather than periodic round-based valuations. A prenup established while the company is private can address both the current illiquid state and the scenario in which shares eventually become liquid.
While private
Selling is restricted
If publicly traded
Lock-up periods eventually expire and shares may become tradable, subject to company policies
The transition from restricted to unrestricted shares creates a moment when paper wealth becomes accessible. Your attorney can help you think through how this transition is addressed.
While private
Valuation is set by funding rounds
If publicly traded
Valuation changes daily based on market conditions
A prenup can describe how pre-marital equity is treated regardless of which price point is eventually realized, providing clarity that does not depend on a specific valuation.

How is Anthropic equity valued for a prenup if there is no public price?
Since Anthropic is privately held, there is no public share price. Common approaches include using the most recent fundraising round valuation, the 409A fair market value, or agreeing to a valuation framework in the prenup itself. Your attorney can help you decide what makes sense for your situation.
What if Anthropic goes public after we marry?
If Anthropic eventually transitions to being publicly traded, your private shares would convert to publicly traded stock. A prenup can address how shares held before the marriage are treated versus shares that vest during the marriage, regardless of whether the company is public or private at the time.
What about refresher grants I receive during the marriage?
New equity grants received after marriage may be treated differently than pre-marital grants. Rules differ by state, and your attorney can review what applies where you live. A prenup can set expectations for how future grants are handled.
What about my RSUs and stock options?
RSUs that vest during a marriage may be treated differently depending on where you live. Stock options add another layer because the exercise price, grant date, and vesting schedule all matter. Your attorney can help you address both vested and unvested equity in the prenup.
What does it cost and how long does it take?
Neptune charges a flat fee of $5,000 per couple, which covers two independent attorneys (one for each partner). There is no payment required to get started, and consultations are free. Turnaround is typically around 3 to 4 weeks when both partners use Neptune attorneys. Rush pricing applies when the wedding is within 45 days.
