This chapter introduces one of the most important and least understood patterns in the business world: the power law. Thiel explains how a tiny number of investments generate virtually all returns, and why this pattern has profound implications far beyond venture capital.
The Power Law
In venture capital, returns do not follow a normal distribution. They follow a power law, where a small number of companies generate the vast majority of returns. The best investment in a portfolio outperforms all others combined. The second-best outperforms all remaining ones combined. And so on.
“The biggest secret in venture capital is that the best investment in a successful fund equals or outperforms the entire rest of the fund combined.”
— Peter Thiel
This is not a minor statistical curiosity. It is the defining feature of the startup ecosystem. Most ventures fail, a few do reasonably well, and a tiny fraction achieve exponential success.
Why Most People Miss It
The power law is counterintuitive because we are trained to think in terms of normal distributions. We expect outcomes to cluster around an average. But in venture capital — and in many other areas of life — outcomes are radically unequal.
Why the Power Law Is Hidden
- It unfolds over time: In the early days of a fund, the differences between investments are not yet visible. Failed companies disappear quickly, but the huge winners take years to emerge.
- Diversification obscures it: Investors spread their bets to manage risk, which masks the fact that almost all returns come from a tiny fraction of bets.
- We prefer narratives of equality: The idea that one company is worth more than all others combined feels unfair, so we resist it.
Implications for Venture Capital
If the power law governs returns, it has radical implications for how VCs should invest. The conventional approach of diversifying across many companies and hoping for a few hits is fundamentally misguided.
VC Strategy Under the Power Law
- Focus, don’t diversify: Only invest in companies that have the potential to return the entire fund
- Every investment must be a potential home run: There is no room for “safe bets” that might return 2x or 3x
- The portfolio approach is dangerous: If you do not think a company can be a massive winner, do not invest at all
- Double down on winners: When you find a power-law company, increase your investment rather than spreading capital
Implications for Everyone
Thiel argues that the power law is not just a VC concept. It applies to career choices, project selection, and life decisions. Most of the value you create will come from a single activity, a single company, or a single market.
The Power Law in Life
- Career: One career path will likely be far more rewarding than all alternatives. Choose carefully rather than keeping all options open.
- Startups: One market or product line will generate most of your company’s value. Focus ruthlessly.
- Time: Some activities produce exponentially more value than others. Identify them and prioritize.
- Relationships: A few key relationships drive most of your personal and professional growth.
“You should focus relentlessly on something you’re good at doing, but before that you must think hard about whether it will be valuable in the future.”
— Peter Thiel
The Power Law and Startup Strategy
For founders, the power law means you should not hedge your bets. Do not start a company just to see what happens. Start one only if you believe it can become enormously valuable. One company, one market, one product can define your entire career and create more value than everything else you might do.
Key Takeaways
- Returns in venture capital follow a power law: the best investment outperforms all others combined
- Most people miss the power law because it unfolds slowly, diversification hides it, and it feels counterintuitive
- VCs should only invest in companies with the potential to return the entire fund
- The power law applies to careers, time allocation, and life decisions — not just investing
- Focus is more valuable than diversification in a power-law world
- Think hard about whether what you are doing has the potential for exponential returns
