Quick Answer
Investor rights that adjust their conversion price downward if the company later issues shares at a lower price.
Anti-dilution protection adjusts an investor's preferred stock conversion price if the company subsequently issues shares at a lower price per share (a down round). This protects investors from value dilution by giving them more shares upon conversion. The two main types are full ratchet (conversion price drops to the new lower price) and weighted average (conversion price is adjusted based on the size and price of the dilutive issuance).
In Practice
An investor owns preferred shares with a $10 conversion price. The company raises a down round at $5/share. With full ratchet, the conversion price drops to $5, doubling the investor's share count. With weighted average, it might drop to $7.50.
Why It Matters
Anti-dilution provisions are standard in VC deals but their type matters enormously. Full ratchet can devastate founder ownership in a down round, while weighted average is significantly more founder-friendly.
VC Beast Take
Anti-dilution protection is one of those terms that seems abstract until it matters — and then it matters enormously. The 2022-2023 downturn triggered more anti-dilution adjustments than the industry had seen in a decade, as companies that raised at peak 2021 valuations were forced into down rounds. The mechanics are straightforward but the second-order effects are brutal: when investors get repriced shares, the dilution falls disproportionately on common stockholders — founders and employees. This is why experienced founders negotiate 'pay-to-play' provisions alongside anti-dilution: if an investor wants price protection, they should also be required to participate in the down round. Pay-to-play forces investors to put up new money or lose their preferential treatment, aligning incentives between capital preservation and company survival.
