What's the read on where public and private valuations are converging?

A significant valuation dichotomy persists between public and private markets, particularly within the technology sector [2, 4]. Several experts note that private company valuations are substantially higher than their public counterparts, with one source estimating them to be almost double [11, 15, 19]. The gap appears most extreme for high-growth companies; one analysis found that while the average public tech company trades at a 3.5x multiple, over 100 private tech companies command an **average 25x multiple** [20, 30]. This disparity is fueled by the AI boom, where private startups with $5-10 million in annual recurring revenue can achieve valuations between $1.5 billion and $3 billion . This occurs while public SaaS companies like ServiceNow and Atlassian are experiencing multiple compression, trading at what are described as record lows due to growth deceleration and competition for capital [5, 6, 14].

This valuation gap is underpinned by a structural shift in capital markets, which has seen the private technology market swell to a **$5 trillion** capitalization, equivalent to a quarter of the S&P 500 [3, 7, 21, 23]. Companies are staying private longer, with the majority of value creation—over 55% for a modern tech company—now occurring before an IPO [3, 27]. Deep private capital pools and the increasing prevalence of liquidity mechanisms like regular tender offers have reduced the urgency for a public listing [3, 8, 10]. Founders can access capital and provide shareholder liquidity while avoiding the perceived short-term focus and punitive nature of public markets, which often struggle to accurately value hyper-growth companies [8, 10]. This dynamic has concentrated value in unlisted firms, driving investors toward private markets to capture growth and achieve diversification that is increasingly difficult in a concentrated S&P 500 [7, 25].

Despite the prevailing narrative of a private market premium, there are signs of convergence and conflicting data points. One analyst contends that private equity valuations are actually at a **15-year low** relative to public markets, a direct contradiction to the venture-focused commentary . This suggests the valuation landscape is not uniform, with potential differences between venture-backed AI, traditional SaaS, and broader private equity. Other experts observe a blurring of lines between the markets, facilitated by a robust secondary market that allows for trading stakes in private companies [26, 28]. The ultimate catalyst for convergence may be the immense capital requirements of sectors like AI and space, which could force mega-unicorns like OpenAI and SpaceX into the public markets around 2026 to access larger capital pools than even private markets can provide [3, 13].
