# What Is Power Law?

> Power law describes the return distribution in venture capital where a small number of investments generate the vast majority of fund profits, while most deals return little or zero.

**Power law** captures how venture outcomes skew heavily: returns concentrate in a few exceptional companies rather than distributing evenly across a fund's portfolio.

### How it works

Empirical VC fund data shows top-decile investments often produce multiples that dwarf the rest of the book. A fund might write off or modestly return on half its companies while one exit returns 50x and carries the fund. That shape drives [portfolio construction](/glossary/portfolio-construction)—enough bets, enough ownership, enough follow-on in winners.

Founders feel power law in fundraising: investors ask whether the business can be "fund returner" scale for their fund size, not merely profitable. Small outcomes may not move DPI for large funds even if founders succeed personally.

### Why it matters

- **Founders:** Position TAM and ambition credibly; power-law investors pass on good small businesses seeking venture-scale capital.
- **Investors:** Fund strategy must match power-law reality—reserves and ownership in winners matter more than minimizing loss counts.

### Common mistake

Assuming disciplined execution alone guarantees venture-scale returns. Power law sectors reward extreme upside scenarios; median outcomes underperform cost of capital for many funds.

## FAQ

### What is power law in simple terms?

In VC, winners are huge and losers are common. One or two companies in a fund often return more than all other investments combined.

### Why does power law matter?

It explains why investors seek companies that could be category leaders—not incremental businesses—and why funds tolerate many failures to find outliers.
