OpenAI and Anthropic are both racing toward what could be two of the largest IPOs in history. If you’re trying to understand the OpenAI vs Anthropic employee equity picture – whether you’ve moved between the two labs, hold offers from both, or just want context beyond your own cap table – this is the comparison you need.
What follows covers equity mechanics, IPO timelines, and governance structure. It is not a comparison of which company is the better investment. That’s not a call we’re in a position to make, and it’s not one you should outsource to an article, either.

Where OpenAI vs Anthropic Employee Equity Diverges
IPO Timeline Certainty
Anthropic’s October 2026 target is closer and, so far, more consistently reported than OpenAI’s. OpenAI’s timeline has already moved once, with CFO Sarah Friar reportedly signaling a 2027 listing instead of the original September 2026 target. If you’re at Anthropic, you likely have a shorter, firmer runway to get your planning done. If you’re at OpenAI, you may have more calendar time – but less certainty about exactly when to have everything in place.
Revenue Growth Story and What It Means for Your Shares
Anthropic’s revenue grew roughly five-fold in about a year (from $9B to a $47B annualized run rate), driven heavily by large enterprise contracts. OpenAI’s growth has also been substantial, but the shape of the story is different – more consumer-facing revenue alongside enterprise deals, and a wider gap between revenue and reported losses. Neither growth story is “better” from where you sit as an employee; they simply create different expectations for how public investors may react to each company’s first few quarterly reports, which in turn affects how volatile your stock may be right after lockup expires.
Governance Structure and What It Means for Shareholders
Both companies use a mission-aligned governance structure that limits a pure shareholder-first model – but the mechanics differ. OpenAI’s nonprofit Foundation directly appoints the for-profit PBC’s board. Anthropic uses an independent Long-Term Benefit Trust that selects the board of directors. OpenAI’s structure has also drawn active regulatory attention – multiple state attorneys general and the House Oversight Committee have requested information related to CEO Sam Altman’s personal investments and potential conflicts of interest. As of publication, Anthropic’s governance structure has not drawn a comparable public inquiry. Neither structure has been tested in public markets yet, and both are worth understanding before you assume your shares behave like typical common stock in a conventional C-corp.
What Doesn’t Change, No Matter Which Company You’re At
Strip away the company-specific details and the underlying planning problem is identical: a large, concentrated, still-illiquid equity position that’s about to become partially liquid on a timeline you don’t fully control.
- Your ISO exercise and AMT strategy doesn’t wait for either company’s IPO date – the math runs on your grant price and current fair market value.
- Your concentration risk is the same problem whether the ticker eventually reads OpenAI or Anthropic – or both, if you’ve worked at each.
- You need a financial advisor who specializes in this exact intersection of tech equity, before the next headline sends a fresh wave of employees from either company into the market for one.

Frequently Asked Questions
Is OpenAI or Anthropic going public first?
As of publication, Anthropic is targeting an October 2026 listing, while OpenAI’s original September 2026 target has reportedly slipped toward 2027. Neither date is confirmed, and both remain subject to change as each company’s confidential S-1 review proceeds.
Which company has a higher valuation, OpenAI or Anthropic?
OpenAI’s most recent private valuation ($852 billion) is lower than Anthropic’s (~$965 billion) as of their respective most recent funding rounds. However, OpenAI is targeting a higher IPO valuation of up to $1 trillion. These are different numbers measuring different things – a private funding round mark versus a target for the public offering – so they aren’t directly comparable without more context.
Do OpenAI and Anthropic employees have the same lockup period?
Reported lockup periods are similar but not identical – roughly 90 to 180 days for OpenAI, and 180 days for Anthropic. Your specific grant agreement and each company’s final IPO prospectus will confirm the exact terms that apply to you.
Should I compare my equity offer at OpenAI versus Anthropic based on valuation alone?
No. Valuation is one input among many – vesting schedule, grant type (RSU vs. ISO vs. NSO), strike price, current equity value, and your own tax situation all matter more to your actual after-tax outcome than a company’s headline valuation. This is exactly the kind of decision worth modeling with a financial advisor rather than estimating from a comparison table.
