PM equity and RSU vesting: what your offer actually means
In 2026, the equity conversation for PMs has split into two completely different games. At established public tech companies (Google, Meta, Microsoft, Stripe), RSUs are liquid and function like deferred cash: the real question is tax efficiency and refresher cadence, not whether the equity will be worth anything. At AI-native companies (Anthropic, OpenAI, xAI, Mistral, Perplexity), the equity is pre-IPO paper with valuations that move 3-5x between funding rounds in 18 months. A $200K RSU grant at a $30B valuation and a $200K RSU grant at a $150B valuation are fundamentally different instruments. A PM who can evaluate product viability but cannot evaluate the viability of their own equity is working with a blind spot in both directions.
How RSUs actually work
An RSU (restricted stock unit) is a promise to deliver shares on a future date, contingent on continued employment. The mechanics in order:
- Grant: The company awards a dollar-denominated grant (e.g., $400K over four years). The share count is calculated by dividing the dollar grant by the 30-day average stock price at grant date. A lower stock price yields more shares on the same dollar grant, which matters if you can time a job change during a dip.
- Cliff: Most schedules have a one-year cliff: zero shares vest until month 12, when 25% delivers at once. Leaving before 12 months means leaving with nothing from that grant.
- Vesting: After the cliff, the remaining 75% typically vests quarterly (6.25% per quarter for three years).
The schedule varies significantly by company, and those differences compound:
| Company | Vesting structure |
|---|---|
| Front-loaded: 33% Y1, 33% Y2, 22% Y3, 12% Y4 | |
| Meta | 25% Y1 cliff, then 6.25%/quarter |
| Amazon | Back-loaded: 5% Y1, 15% Y2, 40% Y3, 40% Y4 |
| Microsoft | Standard: 25%/year quarterly |
The Amazon back-load is the most important structural fact in big-tech comp. Average tech tenure is 2-3 years. A PM who joins Amazon and leaves after two years collects 20% of their headline equity grant. The same two-year stint at Google nets 66%. “Total comp” on Levels.fyi is a four-year average. It is not what you receive if you leave on the median schedule.
The tax hit most articles understate
When RSUs vest, the shares are ordinary income, taxed at your marginal rate in the year of vest. The company withholds at the flat IRS supplemental rate of 22% (for income up to $1M). A senior PM vesting $300K in a single year lands in the 37% federal bracket. That 15-point gap on $300K is $45,000 in additional tax owed at filing, not at withholding. If you did not set aside the difference, April is a surprise.
When you sell:
- Sell immediately at vest: No additional federal tax beyond what you already paid as ordinary income.
- Hold and sell later: Appreciation above the vest-date price is capital gains. Short-term (under one year) is up to 37%. Long-term (over one year) is 0%, 15%, or 20% depending on total income.
A 2017 Journal of Financial Economics study (covering 1983-2006 data) found that 39% of individual stocks lost money and 64% underperformed the broad market. Concentrated stock in a single employer is real portfolio risk. The decision to hold vs. sell immediately should be explicit, not a default.
The refresher treadmill
FAANG packages are designed so that if you stay, your annual comp looks roughly flat year over year. New refresher grants vest on a staggered schedule that offsets the depletion of the original grant. This is intentional retention architecture: base salaries at most big-tech companies cap around $250K-$300K, so the only way to raise total comp without a promotion is through refreshers.
If you never leave, rolling refreshers plus your original grant produce roughly constant annual equity income. That is the design. It is also why total comp projections that extrapolate year-one equity to future years are misleading: they either assume no refreshers (underestimating what a long-tenure PM earns) or assume generous refreshers without specifying how they are determined.
Ask the recruiter before you sign:
- What is the typical annual refresh grant dollar amount at my level?
- Is it fixed, performance-based, or based on unvested equity remaining?
- Does it vest immediately into the current schedule or start a new four-year clock?
RSU vs. startup stock options
Options give you the right to buy shares at the grant-date strike price. RSUs deliver shares outright at vest. The comparison that matters by company stage:
- Pre-seed to Series B: Options with a low 409A (fair market value) can carry real upside: if the strike is $1/share and the exit is $50/share, each option is worth $49. RSUs at this stage are unusual and typically signal the 409A is already high.
- Series C/D onward (or pre-IPO): The 409A is high enough that options carry less leverage. RSUs are standard because the company does not want employees to face large exercise costs at a high-valuation exit.
The 90-day post-termination exercise window is the most overlooked options risk. Standard: when you leave, you have 90 days to exercise vested options or forfeit them. If you hold ISOs worth $200K at a pre-IPO company with no liquidity, you may face a six-figure exercise cost and AMT exposure on paper gains for shares you cannot sell. Some companies (Amplitude, Coinbase, Pinterest) offer extended multi-year windows. It is worth asking at any startup where you hold options.
What happens when you leave or get acquired
Leaving voluntarily or by layoff: Unvested RSUs are forfeited in most cases. Some companies vest a partial tranche if you are within 30 days of a scheduled vest date; check your grant agreement. There is no pro-rata payout for a partial quarter at most public companies.
Acquisition: Whether unvested equity accelerates depends on your agreement:
- Single-trigger acceleration: Unvested shares convert at the close of the deal, regardless of whether your role continues.
- Double-trigger acceleration: Unvested shares only accelerate if the deal closes AND you are terminated or constructively dismissed within a defined window (typically 12-18 months after the deal). Double-trigger is standard at most companies. Single-trigger is rare outside of executive agreements.
If you are at a company in active acquisition conversations, read the equity section of your grant agreement before the deal closes. “Change of control” language determines whether your unvested equity survives.
Pre-IPO AI company equity in 2026
OpenAI, Anthropic, xAI, Mistral, and Perplexity grant equity at valuations set by funding rounds, not by public trading. Three facts that matter when evaluating these offers:
- No public market to sell into without a company-controlled tender offer; secondary market access (Forge Global, Nasdaq Private Market) is company-policy-dependent and often restricted.
- Valuation is a negotiated number between the company and its investors. A $300B valuation is not what the market would pay at IPO; it is what the last investor paid for a preferred share with liquidation preferences you do not hold.
- Apply the same viability judgment you would to a product decision: is this company generating durable revenue at a margin that justifies its valuation, or is the number funded by narrative? PMs who cannot evaluate that for their own comp cannot credibly evaluate it for their product decisions either.
Five questions to ask the recruiter
Most candidates skip at least three of these:
- What is the share count (not just the dollar value of the grant)?
- What is the current 30-day average stock price used for the calculation?
- What is the exact vesting schedule, including cliff date and cadence?
- What is the annual refresh policy at my level, and what do strong performers typically receive?
- Is there an ESPP (Employee Stock Purchase Plan), and what is the discount?
The dollar value of the grant is the least useful number in the offer letter without answers to all five.
