# What Is Pro-Rata Rights?

> Pro-rata rights give an existing investor the option to invest in a future financing in proportion to their current ownership—helping them maintain their stake instead of being diluted.

**Pro-rata rights** entitle an investor to participate in subsequent financings up to their proportional ownership—buying their share of the new round to avoid dilution below their current fully diluted percentage.

### How it works

Term sheets grant major investors pro-rata in future qualified financings. When Series B opens, each holder with pro-rata receives notice of allocation—typically based on pre-round ownership times round size. Investors may take full pro-rata, partial, or waive. Founders and leads size the round to accommodate pro-rata before assigning new investor slots.

Pro-rata differs from [preemptive rights](/glossary/preemptive-rights) in label and document location but functions similarly in venture practice. Super pro-rata or doubling rights appear in competitive rounds but are founder-unfriendly.

### Why it matters

- **Founders:** Early investors with pro-rata can consume meaningful round capacity—communicate timelines and lead terms early to avoid conflicts.
- **Investors:** Pro-rata in breakout companies drives fund returns; missing pro-rata due to reserve shortages hurts DPI.

### Common mistake

Assuming all investors have pro-rata—only major holders typically do; angels and small seeds may be excluded unless side letters say otherwise.

## FAQ

### What is pro-rata rights in simple terms?

If you own 10% and the company raises again, pro-rata lets you buy enough of the new round to still own 10% afterward—if you choose to invest more cash.

### Why do pro-rata rights matter?

Investors protect ownership in winners. Founders must allocate round capacity for pro-rata holders before bringing in new leads, or negotiate waivers.
