What is Weighted Average Anti-Dilution?

Definition

Weighted Average Anti-Dilution

Weighted Average Anti-Dilution is a common investor protection clause that adjusts conversion prices during down rounds based on both the lower share price and the volume of new shares issued.

Why It Matters for Startups

Directly dictates the cap table and dilution structure during fundraising; understanding Weighted Average Anti-Dilution helps founders model equity distributions when structuring rounds for anti-dilution modeling and standard investor contract drafting.

Detailed Deep Dive

Weighted Average Anti-Dilution provides a balanced protection mechanism. Unlike the severe full ratchet, the weighted average conversion price adjustment is moderated by the scale of the down round, protecting investors from loss without completely wiping out founder equity.
