Facebook pre-IPO secondary market and employee lockup (2010–2012)
2010–May 2012What Happened
In the years before Facebook's May 2012 initial public offering, a thriving secondary market emerged on platforms like SecondMarket and SharesPost. Facebook employees began selling shares as early as 2007, and by 2011, average share prices on secondary markets had tripled in a single year. Facebook eventually banned employee share sales in 2010, then ran a company-sponsored tender offer before listing at $38 per share and a $104 billion valuation.
Outcome
Facebook's stock dropped below its IPO price on the first trading day and continued falling for months. Employees who sold pre-IPO at secondary prices actually fared better in the near term.
The stock recovered and ultimately surged, rewarding those who held through the IPO dip. Facebook's experience became the canonical cautionary tale about pre-IPO pricing, showing that tender offer participants and holders can both be right depending on time horizon.
Why It's Relevant Today
Anthropic employees face a structurally similar choice: sell at $350 billion now or hold for a potentially higher IPO price. Facebook's history shows this bet can go either way — the IPO price is not guaranteed to exceed the pre-IPO valuation, especially in the short term.
