OpenAI, Anthropic, Stripe and Databricks make for an unusually attractive list of names to put next to the word Ethereum. They are among the companies held by ARKVX, subject to portfolio changes, but they are not what ARK and Securitize are individually tokenizing.

The onchain asset represents an interest in the ARK Venture Fund itself. ARK continues to manage the portfolio, which invests across private and public companies associated with disruptive technologies. Securitize provides the tokenization and investor infrastructure.

Ethereum becomes a rail for the fund

ARKVX is an actively managed closed-end interval fund. With the new structure, eligible investors can access a tokenized version on Ethereum while the investment strategy behind the vehicle remains unchanged.

That distinction separates this launch from the idea of putting each private holding directly onchain. Owning the tokenized fund does not amount to receiving a freely transferable OpenAI share token. The investor owns an interest in ARKVX through a different infrastructure layer.

The Block reported roughly $1.3 billion in net assets for the fund around the time of the announcement. It is also the first ARK fund to be brought onchain through this model.

Tokenization does not erase the redemption rules

ARK's own disclosures are explicit about the liquidity model. ARKVX shares are not listed on a securities exchange, no secondary market is expected to develop, and liquidity is provided through periodic repurchase offers. Those offers can also be oversubscribed.

Putting ownership records and investor access on Ethereum does not convert that structure into continuous crypto-style trading. The blockchain rail and the legal characteristics of the underlying fund are separate layers.

That may be the more useful part of this launch. Tokenization is increasingly being applied to financial products that already have their own rules rather than to assets designed from scratch for crypto markets. The technology can change how interests are issued, held or administered without rewriting every constraint attached to the instrument.

The partnership predates the tokenized fund

ARK and Securitize had already established a strategic relationship in October 2025, when ARK announced an investment in the tokenization company. At the time, both companies framed the relationship around connecting traditional asset management with blockchain-based financial infrastructure.

ARKVX turns that relationship into a live fund deployment. Securitize handles the onchain issuance and investor experience; ARK remains responsible for investment management and the fund continues to operate under its existing structure.

Access is still subject to investor eligibility and other applicable restrictions. ARK's disclosures continue to describe the fund as illiquid, unlisted and dependent on its periodic repurchase process for redemptions.
