Anthropic Eyes $900B Valuation in New Funding Round

Anthropic is exploring a new funding round that could value the company at over $900 billion, according to reports this week, a figure that would vault it past OpenAI as the most valuable private AI company in the world.

Key points

• Anthropic is reportedly in discussions for a funding round at a valuation exceeding $900 billion, per The Hindu BusinessLine.
• If completed at that figure, Anthropic would surpass OpenAI in private market valuation, a striking reversal given OpenAI’s head start in the consumer AI race.
• Separately, a homeowner made headlines by proposing to swap a mansion for Anthropic equity, an unusual indicator of how broadly retail appetite for Anthropic exposure has grown.
• ZeroHedge also floated the question of whether Anthropic’s commerce-oriented AI capabilities could eventually threaten incumbent platforms like eBay.
• No deal terms, lead investors, or closing timeline have been confirmed in the available sources.

What is driving the $900 billion figure?

The valuation target reflects a broader acceleration in Big Tech AI spending commitments rather than a sudden leap in Anthropic’s fundamentals. As hyperscalers continue to announce multi-billion-dollar infrastructure buildouts, the implied addressable market for frontier model providers has expanded sharply in investor models.

Anthropic’s existing backers already include Google (which has committed up to $40 billion, as covered in our April 26 edition) and Amazon, which has deepened hardware integration ties. A fresh round at $900 billion-plus would represent a significant step up from Anthropic’s prior reported valuation of roughly $61 billion following its Series E in early 2024. The sources available do not specify the size of the round being discussed or who would lead it, so investors should treat the headline number with caution until more detail emerges.

How does this compare to OpenAI?

OpenAI closed a $40 billion round in early 2025 at a $300 billion post-money valuation, later rising to a reported $340 billion in secondary markets. A $900 billion Anthropic valuation would more than double that figure, which is a meaningful claim even in a sector where valuations have moved fast.

It is worth being precise about what is being compared. OpenAI’s valuation has a longer track record of disclosed round data behind it. The $900 billion figure for Anthropic, as reported, is a target being explored, not a closed deal. Private AI valuations at this scale are also driven heavily by strategic investor appetite and compute access agreements rather than revenue multiples alone, which makes direct comparisons to public-market peers imprecise.

Retail appetite and the mansion story

The mansion-for-equity proposal reported by ZeroHedge, while unlikely to close as structured, signals something real: demand for Anthropic equity among non-institutional individuals is running well ahead of available supply. Anthropic remains private, and secondary market access is tightly controlled. The story echoes similar dynamics seen around SpaceX and OpenAI in earlier cycles, where perceived scarcity drove increasingly creative attempts to gain exposure.

For IPO watchers, this retail fervor is a double-edged data point. It supports a strong public debut when the company eventually lists, but it also creates froth risk if headline valuations become untethered from disclosed financials. Anthropic has not announced an IPO date; the most recent guidance from company-adjacent commentary, covered here in late March, pointed to a possible Q4 2026 window.

What to watch

The $900 billion figure needs confirmation and deal terms before it changes the investment calculus materially. Key questions include who is anchoring the round, whether existing investors like Google and Amazon are participating further, and what governance or liquidity provisions accompany any new shares. Until those details surface, the number is a signal of directional momentum rather than a settled fact.
