Cathie Wood brings $1.3 billion SpaceX and OpenAI fund onchain

Cathie Wood's ARK Invest is tokenizing its about $1.3 billion ARK Venture Fund on Ethereum. ARK Invest and Securitize announced the move on Sept. 24. The fund owns stakes in SpaceX, OpenAI, and Anthropic. OpenAI and Anthropic do not trade on any stock exchange. About 78% of the fund was invested in companies without a public stock ticker as of August 31, according to an ARK holdings file. SpaceX was the fund's top position at 7.54%. OpenAI represented 5.26% of the fund. Anthropic represented 3.86%. Eligible investors can buy exposure to the fund's portfolio through Securitize. The portfolio is mostly invested in private companies. The fund first opened to investors in September 2022. ARK launched it with a $500 minimum. The fund is an interval fund. Its prospectus schedules share buybacks quarterly. The release warns that buybacks may be oversubscribed. ARK says no secondary market is expected to develop. The fund's annual expenses are 2.9% after fee waivers. A September 21 SEC order lets the fund offer a tokenized share class. The share class may trade on alternative trading systems. Cathie Wood said tokenization has the potential to fundamentally reshape how investors access and participate in private and public financial markets. Securitize tokenized BlackRock's BUIDL fund on Ethereum in March 2024. ARK announced a strategic investment in Securitize in October 2025. Securitize shares have rallied since the SEC opened a path for tokenized stock trading on Sept. 17. SEC filings show that the fund's net assets rose from $208 million in July 2025 to $558 million by January 2026.
