What you actually hold at Mercury

Mercury equity is typically stock options and, for later grants, RSUs. Options you exercise into shares; RSUs settle on a liquidity event or set date. You can generally only sell settled shares. Mercury hasn’t run a widely-reported regular tender programme, so knowing whether and how you can sell matters. Check your grant for vested amount, strike and settlement terms.

How Mercury equity turns into cash

Mercury is private, with no open market. Liquidity has come mainly through its funding rounds rather than a regular tender programme. Outside those, selling is subject to Mercury’s transfer rules (right of first refusal, company approval). Don’t assume a tender window will appear on a fixed schedule.

The decision you’re probably facing

No regular tender — confirm you can sell before you exercise. Because Mercury hasn’t run a regular tender programme, the key question is whether your grant is sellable at all before an exit, and on what terms. Exercising options creates a tax bill — so confirm transferability first, rather than owing tax on shares you can’t move.

The practical steps: confirm what you hold and whether it’s transferable, value it at ~$5.2 billion, and model the tax of exercising or settling.

The tax reality (US)

Most US startup equity is taxed one of two ways. RSUs are ordinary income when they settle (on a liquidity event or set date), with employer withholding that can fall short at higher incomes; later gains are capital gains. Options cost the strike to exercise and, for ISOs, can trigger AMT — use the ISO/AMT calculator. Selling in a tender or secondary is a capital-gains event on any rise since you acquired the shares. Full method in our methodology.

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.
