Selling shares · OpenAI

How to sell your OpenAI stock

Q: Do I own shares in OpenAI?

Generally no. OpenAI staff typically hold PPUs (profit participation units) - a contractual right to a share of OpenAI's profits that vests over time - rather than shares or stock options. There's no strike price and nothing to exercise.

Q: Can I sell my OpenAI PPUs?

Usually only when OpenAI runs a tender offer: the company or an incoming investor buys a limited amount of vested PPUs at a set price, for a set window. Recent tenders (including a SoftBank-enabled sale) let current and former staff cash out meaningful amounts. Outside a tender, PPUs generally can't be sold to an outside buyer.

Q: How are OpenAI PPUs taxed?

Generally as ordinary income when they pay out or you sell in a tender - like a cash bonus rather than a stock sale. There's usually no capital-gains or AMT treatment and no 83(b), because you never hold a conventional share. Take advice specific to PPUs.

At OpenAI you don’t hold shares or stock options — you hold PPUs (profit participation units). That one fact changes everything about selling and tax. Here’s what you actually have, how a tender lets you cash out, and what you’ll owe.

Status Privately held · Reviewed November 2026

OpenAI is a private US AI company — still private as of November 2026. After an October 2025 restructuring it runs as a for-profit public-benefit corporation controlled by the OpenAI nonprofit, with Microsoft holding about 27% and a valuation around $500 billion; an IPO is reportedly a 2027 question. You probably don’t want the corporate diagram — you want to know what your PPUs are worth and how to turn them into cash. This guide is for the OpenAI holder.

What you actually hold at OpenAI

This is the big one. OpenAI staff generally don’t receive shares or options — they receive PPUs (profit participation units): a contractual right to a slice of OpenAI’s future profits that vests over time. You don’t “exercise” a PPU, there’s no strike price, and historically returns were capped. Most of the usual startup-equity playbook (83(b), AMT, ISO/NSO) simply doesn’t apply. What matters is your vested PPU count, what each is worth at the latest valuation, and whether a tender is open.

How OpenAI equity turns into cash

OpenAI is private, so there’s no open market. Liquidity has come through company-run tender offers — OpenAI (or an incoming investor such as SoftBank) offers to buy a limited amount of vested PPUs at a set price, for a set window. Recent windows let staff sell meaningful sums. Outside a tender, PPUs generally can’t be sold to an outside buyer the way shares can, because they’re a contract with the company, not a transferable share certificate.

The decision you’re probably facing

PPUs are not shares — don’t plan like they are. Because a PPU is a contractual profit share, not stock, your decisions are different: there’s nothing to exercise, no AMT to model, and you usually can’t sell on a secondary platform. The real question is how many PPUs to sell when a tender opens, knowing the proceeds are taxed as ordinary income (below) and that holding means betting on OpenAI’s profits and an eventual IPO.

So the practical steps are: confirm your vested PPU count, value it at the latest tender/valuation, and work out the after-tax cash from selling a given amount in the next window. The estimator and report help you put real numbers on it.

The tax reality (US)

PPU proceeds are generally taxed as ordinary income when they pay out or you sell in a tender — closer to a cash bonus than a stock sale. There’s usually no capital-gains or AMT treatment and no 83(b) election, because you never hold a conventional share with a cost basis. Employers typically withhold, but withholding can fall short at higher incomes. This is genuinely different from options/RSUs — see our methodology, and take advice specific to PPUs.

What to expect on price

A tender has a set price; a private secondary to an outside buyer usually happens at a discount to the last headline valuation — because the buyer takes an illiquid minority stake, and you likely hold common shares worth less than investors’ preferred. See what discount is fair.

Work out your OpenAI PPUs

Before the next tender, get the numbers straight: how many PPUs you’ve vested, what they’re worth at the latest valuation, the ordinary-income tax, and the after-tax cash from selling a given amount. The free estimator gives you the range; the report runs it on your numbers.
