Bloomberg Reveals Anthropic Shareholder Returns, Spark Capital Invested $75 Million in 2023, Its Largest Single Investment at the Time
Bloomberg has disclosed the shareholder returns of Anthropic. Spark Capital invested $75 million in 2023, making it its largest single investment at that time, with current holdings valued at approximately $7 billion, and it is the only known VC with a seat on the board.
Menlo Ventures began investing in 2023 when Anthropic had very little revenue and was seen as a competitor to OpenAI. It has cumulatively invested over $1 billion, with holdings valued at approximately $14 billion. Iconiq entered in 2025 when the valuation had reached $183 billion, with cumulative investments exceeding $6 billion and holdings valued at around $17 billion.
Sequoia started investing earlier this year, investing about $3 billion for approximately 1% equity, valued at nearly $10 billion according to the latest private market valuation. Singapore's sovereign fund GIC has cumulatively invested over $4.5 billion, also holding about 1%. Sound Ventures (involved with Ashton Kutcher) invested $35 million at a $5 billion valuation in 2023 and has continued to increase its stake.
The latest private market valuation of Anthropic is approximately $965 billion, with some market expectations for an IPO valuation reaching $2 trillion. The IPO will further increase the wealth of the seven billionaire co-founders and may make thousands of employees millionaires. Amazon, Google, and Nvidia are both power suppliers and significant shareholders.
Paper returns need to be realized through the IPO and subsequent sell-offs. Anthropic is advancing its IPO process, with some investors already achieving several times their returns even at extremely high valuations. Both early small bets and later large follow-ups have generated significant paper gains.
In terms of market mechanisms, funds are concentrated in leading model companies, with early VCs and later large institutions and sovereign funds sharing in valuation expansion. Suppliers participate in profit distribution through equity, creating a cycle of computing power investment and equity returns. The traditional small early VC model is under pressure in the context of super-large-scale AI financing.

Spark Capital led the investment in Anthropic with $75 million in 2023 when the company's valuation was around $5 billion and had very little revenue, securing a board seat. Menlo Ventures entered at the same time and continued to increase its stake through special purpose vehicles. Iconiq and GIC made large investments during the high valuation phase after 2025, while Sequoia only began building its position in 2026.
In terms of capital pathways, early small funds exchanged for board seats and high multiple returns, while later billions of dollars entered at higher valuations for around 1% equity. Companies like Amazon, Google, and Nvidia lock in computing power customers through equity investments, creating a dual revenue path of "chip and cloud service sales + equity appreciation." Funds are primarily directed towards model training and infrastructure expansion.
This mirrors the path of early small investors in Facebook receiving huge returns at IPO or SpaceX's later large-scale financing continuing to elevate valuations. Current AI model companies are in a phase of transitioning from private high valuations to the public market, with leading companies absorbing the vast majority of capital, making it difficult for smaller players to enter the core equity layer.
Essentially, this represents capital concentration. The computing power and data barriers of model training allow a few companies to absorb the majority of funds, requiring investors to invest in the tens of billions to obtain meaningful equity stakes. The mechanism is that scale effects and network effects reinforce the advantages of leading companies, further concentrating capital on validated paths, making the extremely high multiple returns of early small bets an exception rather than the norm.
