SpaceX’s anticipated initial public offering, along with those of OpenAI and Anthropic, looms large over the private market, potentially creating a significant shift in liquidity and investor focus, according to a latest report by PitchBook. The potential for these mega-cap companies to enter the public market later this year could abandon a void in the private secondary market, where a disproportionate amount of trading volume is currently concentrated in a small number of highly valued firms.
Approximately 86% of private secondary trading volume is tied to the 20 most valuable companies in the private market—a group PitchBook analysts have dubbed “the magnificent few.” This concentration highlights the limited access to liquidity for shares in a broader range of venture capital-backed companies. Emily Zheng, a PitchBook analyst, noted that the IPO market has been “pretty paltry for several years now, illustrating the narrative that companies are staying private for longer,” as reported by Yahoo Finance.
The trend of companies delaying IPOs is driven, in part, by the availability of substantial private capital from venture capital, growth equity, and private credit. This allows companies to achieve significant scale and enterprise value without the scrutiny and regulatory requirements of public markets. In 2025, private market exits generated $154 billion in exit value from approximately $15.7 billion invested, demonstrating a substantial return for investors and reinforcing the shift of value creation occurring before companies go public, according to FNEX. Notable exits included Wiz, Windsurf, Circle, and Figma.
However, the limited number of IPOs also restricts opportunities for broader investor participation. While secondary markets and exclusive vehicles are emerging to provide access to private shares, these options are often limited to accredited investors or institutional players. The impending IPOs of SpaceX, OpenAI, and Anthropic could alter this dynamic, potentially drawing capital away from the private market and offering a more accessible route for public investors to gain exposure to high-growth companies.
Despite the recent sluggishness, the IPO market isn’t entirely dormant. Wellington Management argues that IPOs are “just napping,” pointing out that the public market processes significantly more volume than all of private equity combined. Wellington Management suggests that going public remains crucial for most companies seeking substantial capital and liquidity.
The timing of these potential IPOs is crucial. While the IPO window has technically opened, it remains selective, favoring companies in specific sectors demonstrating a clear path to profitability. The broader economic climate, including interest rate fluctuations and geopolitical uncertainties, will also play a significant role in determining investor appetite for new public offerings. The concentration of trading volume in “the magnificent few” suggests that the private market’s structure could significantly shape public access to private shares, and the IPO market outlook remains uncertain.
