Anti-Dilution
A clause that protects investors from losing value when a company raises money at a lower valuation than their original investment.
By Amit Tyagi, Fitoor Capital · AletheiaAI Glossary
Definition
Anti-dilution protection kicks in when a startup raises a new round at a lower valuation than the previous round — a "down round." Without this protection, earlier investors who paid a high price per share now hold shares worth less than they paid. Anti-dilution adjusts the conversion price of their shares downward, effectively giving them more shares to compensate.
Two main types: broad-based weighted average (the most common, most founder-friendly — the new conversion price is a weighted average factoring in how much new capital was raised and at what price) and full ratchet (the most investor-friendly, most punishing — the earlier investor's price drops all the way to the new round's lower price, regardless of amount raised).
India Context
Anti-dilution is standard in Indian term sheets, almost always as broad-based weighted average. Full ratchet provisions are rare in reputable Indian VC deals but sometimes appear in bridge rounds or strategic investor term sheets. During the 2022–2023 funding winter, many Indian startups faced down rounds — triggering anti-dilution clauses that significantly increased investor share counts and further diluted founders.
Indian founders should model down-round scenarios during good times. Running a 30% valuation haircut through your cap table shows exactly what anti-dilution would do to your ownership.
Example
An investor buys shares at ₹100 per share (Series A, ₹20 crore valuation). Down round: Series B raises at ₹60 per share (₹12 crore valuation). With broad-based weighted average, the anti-dilution formula might reset their price to ₹80/share — giving them 25% more shares. With full ratchet, their price drops to ₹60 — giving them 67% more shares and severely diluting founders.
