The Great Migration: Why the World's Best Tech Companies Are Choosing to Stay Private

In a recent episode of the Odd Lots podcast, David George, Head of Growth at Andreessen Horowitz (A16Z), provided a compelling analysis of the shifting landscape between public and private capital markets. As companies like SpaceX, Stripe, and OpenAI continue to thrive outside the public eye, the traditional narrative of the "IPO as the ultimate goal" is undergoing a fundamental transformation.

The Rise of the Private Mega-Cap

George highlights a staggering shift in market composition: private, highly valued technology companies now represent approximately $5 trillion in market cap—nearly a quarter of the S&P 500. He notes that this sector has grown 10x over the last decade, while the number of public companies has been cut in half. According to George, the "best of the best" companies are no longer rushing to go public; instead, they are staying private longer because the private capital markets have become deeper and more liquid, allowing them to fund their operations without the burden of public market volatility.

The Structural Challenges of Going Public

Why do founders avoid the public spotlight? George points to several structural hurdles:

  • Operational Costs and Complexity: Being a public company involves significant regulatory and administrative costs, which can be an "operational headache" for smaller or mid-cap firms.
  • Lack of Analyst Coverage: Public market investors and banks are increasingly tilted toward large-cap companies. Small-cap firms struggle to gain the attention of investors, making it difficult to maintain liquidity and valuation growth.
  • Volatility and Employee Morale: Founders have witnessed the boom-and-bust cycles of 2021–2023. By staying private, founders can better control their stock price and minimize the demoralizing effects of extreme volatility on employee compensation packages.

Solving the Liquidity Puzzle: The Role of Tender Offers

One of the most compelling arguments for going public has traditionally been employee liquidity. George explains that private companies have effectively countered this by implementing regular "tender offers." By allowing employees to sell a portion of their vested stock annually—a practice famously perfected by SpaceX—companies can provide the financial benefits of public equity while maintaining the privacy and control of a private entity. This, George argues, is a "pretty compelling alternative" to the quarterly RSU deposits seen at public giants like Meta or Alphabet.

The AI Paradigm and the Future of Software

George is particularly bullish on AI, noting that these companies are "speed running the process of company growth" at rates never seen before. While AI requires massive capital investment—what George describes as a $5 trillion infrastructure build-out over the next five to seven years—he remains optimistic about demand. Unlike the fiber-optic build-out of the internet era, where "dark fiber" sat unused, modern GPUs and TPUs are utilized almost immediately upon deployment.

Regarding the software industry, George warns that legacy incumbents are being "crushed" because they are failing to capture the growth shifting toward AI initiatives. He predicts a major business model shift: the transition from seat-based subscriptions to outcome-based pricing. As enterprises demand verifiable results, this shift will favor newcomers who can build AI-native solutions, while incumbents risk becoming mere "systems of record" that are built upon but not actively innovated.

Conclusion: A New Era of Value Creation

Historical data underscores this shift. Ten years ago, 88% of market cap creation for top tech companies happened after they went public. For recent IPOs, that number has reversed, with 55% of value creation occurring in the private markets. As David George concludes, for investors seeking the "highest growth, most promising companies," the private market is now the primary arena where the next generation of industry leaders is being forged.
