Index Ventures Raises $2 Billion Across Three Funds After Wiz Sale Windfall

Index Ventures announced Friday it raised $2 billion in fresh capital spread across three funds, according to TechCrunch. The 30-year-old venture firm pulled in $400 million for a new seed-focused fund and $900 million for its core venture fund. It also added $700 million to a $1.5 billion growth fund it raised back in 2024, pushing its total available capital to $3.5 billion.

This is Index's second big raise in three years. The firm closed $2.3 billion across two funds in 2023, including $800 million for a predecessor venture vehicle, TechCrunch reported. Compare that to the new haul and the growth-fund math checks out: Index didn't need to raise a brand-new growth fund this time around, it just added money to the one already in play.

Index has resisted the urge to balloon its fund sizes, something plenty of other venture firms have not done in recent years as AI hype pushed valuations and fund targets skyward. A firm that raises bigger and bigger funds needs bigger and bigger exits to justify the fees, and bigger funds often mean writing bigger checks into more speculative deals just to deploy the capital. Index staying roughly in its lane is either discipline or caution, depending on who's judging.

The Wiz Payout Behind the Timing

The raise lands just months after one of the largest exits in tech history closed. Wiz, the cloud security company Index backed at the seed stage, completed its $32 billion sale to Alphabet earlier this year. Index became Wiz's largest outside shareholder with a 12% stake, a position Reuters has reported was likely worth $3.8 billion.

That's real money landing in Index's coffers and, by extension, in the pockets of the limited partners, pension funds, endowments, and family offices who fund Index's vehicles. A win of that size makes it a lot easier to go back to those same LPs and ask for another $2 billion. Investors chase track records, and a $3.8 billion payout on a seed check is the kind of track record that opens wallets.

Index was also an early investor in Figma, which went public last year. Two marquee exits in close succession gives the firm a strong pitch heading into fundraising conversations, and it shows in the numbers.

Where the New Money Is Headed

Index's recent bets lean heavily into artificial intelligence. The firm's portfolio includes Physical Intelligence, a robotics company, and Fireworks AI, an inference platform. It's also an investor in Anthropic, having put money in when the AI model maker raised at a $183 billion valuation last September.

That's a significant valuation for a company that, like most frontier AI labs, is still burning enormous amounts of cash to train and run models. Whether $183 billion holds up depends entirely on whether Anthropic and its peers can turn that spending into durable revenue, something that remains an open question across the entire AI sector. Index is betting yes, but so is nearly every other major fund right now. The concentration itself is notable given how concentrated venture capital has become in a handful of AI names.

What's Left Unanswered

TechCrunch's report lays out the raise cleanly but doesn't get into how Index plans to deploy the new seed and venture capital, or which sectors beyond AI and robotics will see checks. It also doesn't address whether the firm faces any pressure from LPs to diversify beyond AI given how crowded that trade has gotten.

The bigger unresolved question applies to the whole venture industry, not just Index: what happens to fund performance if AI valuations correct. A firm sitting on $3.5 billion in fresh capital has plenty of room to be patient. Whether it stays disciplined when everyone else is still chasing the same handful of AI unicorns will become clear over the next year.
