Artificial intelligence is entering a new stage. After years of record private investment, leading AI companies are preparing to test public market confidence.
Anthropic’s confidential IPO filing is a major signal for the sector. The company could seek a valuation above $1 trillion, placing it among the most valuable technology businesses in the world.
A Rapid Rise to Trillion-Dollar Status
Anthropic’s growth has been exceptional. In March 2025, the company was valued at about $60 billion. Fifteen months later, its valuation reached $900 billion before the latest funding round.
The company also secured $65 billion in new financing from institutional investors, venture firms, and strategic partners. This may become its final private funding round before a public listing.
Revenue growth has strengthened the investment case. Annualised revenue reportedly passed $47 billion in May 2026, after growing fivefold since the start of the year.
The Emerging AI IPO Wave
Anthropic is not alone. OpenAI, recently valued at about $852 billion, is also preparing for a potential listing. SpaceX is targeting an IPO valuation of around $1.75 trillion.
Together, these companies could bring more than $3.5 trillion in potential market value to public investors. Their listings may become one of the largest tests of confidence in the AI economy.
This shift shows how quickly AI has moved from research labs to capital markets. Public investors will now assess whether growth, demand, and infrastructure plans can support such valuations.
Infrastructure Becomes the New Competitive Advantage
Behind the valuations is a major infrastructure race. Advanced AI models require huge computing capacity, specialised chips, data centres, and energy resources.
Anthropic has signed major agreements with Google, Amazon, and Broadcom to secure computing power. These commitments could be worth hundreds of billions of dollars over the coming years.
The company has also agreed to lease two large data centre campuses from SpaceX. The deal is valued at around $15 billion per year, showing the scale of capital needed to compete in AI.
A Crucial Test for Investors
The IPO wave will test how public markets value AI businesses. Private investors have supported rapid growth and high valuations, but public markets usually demand more transparency.
Investors will focus on revenue quality, margins, cash burn, and long-term profitability. Strong growth alone may not be enough if infrastructure costs continue rising.
For the AI sector, the outcome will be important. Successful listings could unlock more capital. Weak demand could force companies to slow spending and prove stronger financial discipline.
Looking Ahead
Anthropic’s IPO filing is more than a company milestone. It reflects the transition of AI from a private funding story to a public market investment category.
The coming months will show whether investors are ready to support trillion-dollar AI companies at scale. The answer will shape the next phase of artificial intelligence, capital markets, and global technology competition.
