The landscape of enterprise software is undergoing a seismic shift, with the top 10 private companies now collectively valued at an astonishing $1.93 trillion, surpassing the $1.88 trillion value of the entire Sapphire Pure SaaS Index, which tracks 115 public companies. This unexpected shift underscores the rapid ascendancy of private firms, particularly in the AI sector, as they capitalize on burgeoning market opportunities.
Leading this charge is Anthropic, which has seen its valuation soar to as high as $1 trillion in secondary markets, markedly higher than its primary round valuation of $380 billion established earlier this year. With an annualized revenue leap from $9 billion to $30 billion in just four months, Anthropic’s rise is emblematic of the explosive growth characterizing the AI-native landscape. The combined valuation of Anthropic and other top private companies pushes the total private software valuation beyond $2.5 trillion.
Among the top private players, OpenAI holds a hefty valuation of $840 billion, while other notable companies like Stripe and Databricks command valuations of $159 billion and $134 billion, respectively. The emergence of these firms is particularly striking given that most were founded within the last five years; for instance, Anthropic was established in 2021 and xAI in 2023. As such, the current top 10 list starkly contrasts with that of 2020 and will likely continue to evolve rapidly.
The Sapphire Pure SaaS Index, which includes major public players like Palantir ($324 billion), Shopify ($211 billion), and Salesforce ($176 billion), has faced challenges, losing approximately 30% of its value since its peak in October 2025. The index now reflects a total market capitalization of $1.88 trillion. As it stands, Anthropic alone represents more than half the total valuation of the public pure-play SaaS market, highlighting a significant paradigm shift.
This evolution in market dynamics has led to the top 10 private companies now comprising over 30% of the entire public software market. The Sapphire Broad Software Index, which encompasses all major software incumbents such as Microsoft, Oracle, and SAP, is valued at $6.37 trillion. The concentration of value among the ten private firms is unprecedented, driven by their ability to rapidly capture market share and innovate.
The pace of growth in this sector is remarkable. The overall valuation of enterprise software unicorns rose from $1.64 trillion in 2021 to $4.12 trillion in 2025, with the top five companies’ share increasing from 13% to 43% over the same period. Notably, the three leading AI labs—OpenAI, Anthropic, and xAI—accounted for 73% of the valuation growth in 2025 alone.
As the secondary market gains prominence, the disparity between private and public market valuations has widened. The secondary market for Anthropic saw it valued at $1 trillion shortly after its $380 billion primary round, suggesting that investor sentiment is far outpacing public market performance. In contrast, the Sapphire Pure SaaS Index has seen its multiples compress significantly, now trading at 3.1x NTM revenue, down from a peak of 15.2x in December 2020.
The implications of this shift are profound. Public B2B SaaS and private AI-native companies are no longer competing in the same arena. The traditional playbook that emphasized per-seat pricing and moderate growth is rapidly becoming obsolete. Instead, a new model focused on usage-based pricing, extraordinary growth rates, and remarkable efficiency metrics is taking hold, with companies like Anthropic showcasing growth rates of up to 1,400% year-over-year.
As we advance, it is clear that the private AI sector is entering a new era of value creation, one that may redefine the benchmarks for success in enterprise software. The first quarter of 2026 may mark a pivotal crossover moment in this transformation, as the top private AI-native companies eclipse the public SaaS market, reshaping the future landscape of the industry.
