Cap Table: What It Means and How to Negotiate It (2026)

What is a cap table? A cap table (capitalisation table) is the record of who owns what in a company. It lists every shareholder and their shares, plus everything that could become shares: granted options, the unallocated option pool, warrants, and convertible instruments such as SAFEs or convertible notes. In short, it is the single source of truth for ownership, and it changes every time the company raises money, grants options, or converts an instrument. A cap table is not itself a thing you "negotiate", but the terms that feed into it, valuation, option pool, conversions and new share issues, are negotiated hard, because they decide how much of the company you keep. Understanding the cap table is what lets you see through a term sheet to the ownership it actually produces. This article is general guidance, not legal advice. Have a qualified professional review your financing documents. ## Fully diluted ownership: read the denominator Ownership percentages are almost always quoted on a "fully diluted" basis, meaning the denominator includes every share that could exist if all options, warrants and convertibles were exercised or converted, not just shares issued today. This matters because the same holding can be a different percentage depending on what is counted: - Issued shares exist now.

• Fully diluted shares add granted options, the unallocated option pool, warrants and convertible instruments. Always ask exactly what is in the denominator. Some cap tables leave out SAFE conversions or a proposed pool increase, which flatters a percentage. "Fully diluted" is only meaningful with its assumptions stated. ## Pre-money, post-money and your dilution Two numbers drive the dilution maths at a round: - Pre-money valuation is the company's value before the new investment.
• Post-money valuation is pre-money plus the money invested. The investor's stake is their investment divided by the post-money. For example, a company with a USD 4 million pre-money that raises USD 1 million has a USD 5 million post-money, so the investor owns 20% (1 divided by 5), and the founders go from 100% to 80% in that round. Because "valuation" can mean either figure, always confirm which one an investor means; the difference can roughly double your apparent dilution. Dilution compounds across rounds. A founder at 50% who is diluted 20% in each of three rounds ends near 25%, before counting any option pool. Every round and every pool top-up chips away at the percentage, which is why founders watch the cumulative picture, not just one round. ## The terms that quietly move the cap table - The option pool (and the pool shuffle). If a larger pool is required pre-money, those pool shares dilute existing holders, mainly founders, not the new investor. This lowers your effective pre-money valuation even if the headline looks unchanged.
• Convertible instruments. SAFEs and convertible notes convert into shares later, often at a discount or a valuation cap, so they can dilute more than the headline round suggests. Model their conversion before you sign.
• Liquidation preferences and anti-dilution. These do not change the percentage lines on the cap table directly, but they change who gets what on an exit or a down round, so read them alongside the ownership numbers.
• Warrants and advisor shares. Small-looking grants add up in the fully diluted count. ## How to negotiate with the cap table in mind - Model the fully diluted cap table before signing, including the pool and all convertibles, so you see your real post-round ownership, not the headline.
• Treat the option pool as a valuation issue (see the option pool shuffle): a bigger pre-money pool is extra dilution, so trade it against valuation.
• Clarify pre-money vs post-money on every term sheet before reacting to a valuation.
• Account for every SAFE and note at its conversion terms, not its face value.
• Keep the cap table clean and current, because a messy or stale cap table slows diligence and can cost you leverage in a round. ## Common mistakes to avoid - Reading ownership off issued shares only, ignoring the fully diluted count.
• Not asking what is in the "fully diluted" denominator (pool? SAFEs?).
• Confusing pre-money and post-money valuation.
• Treating a large pre-money option pool as free when it is pure founder dilution.
• Letting SAFEs and notes pile up without modelling their conversion.
• Running the cap table in an unversioned spreadsheet that nobody trusts. ## A note on jurisdiction The cap table concept is universal, and the dilution maths is the same everywhere. What varies by jurisdiction is the legal machinery behind entries on it: share-issue approvals, pre-emption rules (for example Section 62 of the Companies Act, 2013, in India), the instruments used (SAFEs are common in the US and increasingly elsewhere; some jurisdictions prefer convertible notes or compulsorily convertible instruments), and filing requirements. Treat "varies by jurisdiction" as the default and make sure the cap table reflects what the company's statutory records actually say.

Drafting, reviewing, tracking and governing those underlying contracts can live in one AI workspace tuned to how your company raises and grants equity, with the ownership-affecting clauses linked and the approval and conversion dates in view, so the paperwork and the cap table tell the same story. Adira is one tool built around that single-workspace idea for the contracts a cap table rests on. This guide is enough to read a cap table and see through a term sheet.
