Spark Capital’s $75 million 2023 investment in Anthropic is reportedly now worth about $7 billion
According to Bloomberg on October 22, 2026, citing a person familiar with the matter, venture capital firm Spark Capital invested $75 million in Anthropic in 2023, its largest single check ever. At Anthropic’s latest private-market valuation of about $965 billion, that stake is now worth about $7 billion. Spark is currently the only known venture capital firm with a board seat at Anthropic. The value is an unrealized paper valuation. Anthropic is preparing for an IPO, and some in the market expect the listing valuation could be as high as $2 trillion. Spark did not respond to a request for comment.

Yasmin Razavi is a General Partner at Spark Capital. In May 2023, she led Anthropic’s $450 million Series C financing round (at a valuation of about $5 billion) and therefore joined the board, becoming the only known external venture capitalist holding a board seat at Anthropic. Spark had previously invested in companies such as Postmates and Discord, but this investment in Anthropic, which Razavi called the company’s largest check ever, elevated its reputation in Silicon Valley from a “good VC” to a landmark case.
On the capital path, Spark first led an early round with $75 million in exchange for equity and a board seat; it later continued to add through multiple funds, with total investment of about $777 million across six rounds, including the $75 million in the 2023 Series C. The funds were used to support Claude product development and safety research. Entering at the early low valuation of about $5 billion allowed it to achieve a high multiple on paper at the current private valuation of $965 billion, while institutions that entered at the same time or later (such as Iconiq, which invested more than $6 billion at a higher valuation and holds a stake worth about $17 billion) have significantly lower multiples.
Compared with Sound Ventures (which invested $35 million in the same round), Spark secured a board seat governance right because of its earlier and larger commitment, while Sound only obtained financial exposure. This is consistent with the evolution of the traditional VC model of “capital in exchange for control” during an extremely long private-company period: large early checks can still lock in scarce governance positions, while large late-stage checks are more purely financial participation.
This change turned Spark from an ordinary early-stage investor into an institution with the only external board seat in Anthropic’s governance structure, improving its bargaining position in subsequent financing and strategic discussions; at the same time, the paper return from a single early investment has already covered several times the size of its related funds, changing the overall return distribution of that fund. If the IPO proceeds as expected, the paper value could expand further, but actual monetization will still depend on the listing price, lock-up period, and liquidity arrangements.

A large early low-valuation check plus a board seat can, as valuation rapidly expands, lock in both financial multiples and a governance position.
Early and late investors in the same company can have paper return multiples that differ by dozens of times because of different entry times.
