Putting an investment on a blockchain can change how it is issued, recorded and distributed.
It cannot guarantee that someone will be there to buy it.
That distinction is becoming more important as tokenization expands beyond Treasuries and publicly traded securities into private markets. ARK Invest is providing a useful example with the tokenization of its ARK Venture Fund through Securitize.
The fund gives investors exposure to private companies including OpenAI, Anthropic, Stripe and Databricks alongside publicly traded holdings. Its shares can now be accessed through blockchain infrastructure on Ethereum.
But the economics of exiting the investment remain much closer to private markets than to crypto markets.
ARK describes the vehicle as a closed-end interval fund with limited liquidity. Its shares are not listed on an exchange, the manager does not expect a secondary market to develop, and investors primarily rely on periodic repurchase offers when they want to exit.
The fund may now exist on-chain.
A continuously tradable market for it does not.
A Token Can Move Without Having Somewhere to Trade
Tokenization and liquidity are often discussed as if one naturally produces the other.
They solve different problems.
Blockchain infrastructure can provide a digital ownership record and allow an asset to be transferred under a defined set of rules. That can make financial products easier to administer and potentially easier to distribute.
Liquidity requires something else: buyers.
A seller needs a counterparty willing to take the other side of a transaction at an acceptable price. A functioning market also needs price discovery, trading infrastructure and enough depth for investors to enter and exit without dramatically affecting the asset’s value.
Creating a token does not automatically create any of those things.
ARKVX makes that distinction unusually visible.
The fund conducts quarterly repurchase offers that are generally limited to approximately 5% of outstanding shares. If investors collectively request more than the fund is willing to repurchase, they may not be able to sell everything they want.
Those constraints remain relevant after tokenization.
Ethereum can change the infrastructure supporting ownership of the investment. It does not create an unlimited pool of investors waiting on the other side.
The Assets Underneath Are Still Private
The reason becomes clearer when looking inside the fund.
ARKVX was designed in part to provide access to companies that investors cannot simply buy through a brokerage account.
OpenAI, Anthropic and other private companies do not trade continuously on public exchanges. Stakes in private businesses can face transfer restrictions, infrequent pricing events and a much smaller universe of potential buyers.
Those characteristics do not disappear because a fund holding exposure to them has been tokenized.
This creates two separate layers.
At the top sits the fund interest, which can now use blockchain infrastructure.
Underneath sit investments whose economics remain tied to private markets.
The top layer can become technologically more portable without making the bottom layer economically more liquid.
That matters because a financial product cannot promise unlimited liquidity indefinitely if the assets backing it cannot be sold just as easily.
Blockchain can change the wrapper. It cannot make that mismatch disappear.
Access Is Not the Same as an Exit
ARKVX was already unusual before its move on-chain.
Traditional venture capital has historically been dominated by institutions and wealthy investors committing large amounts of capital for long periods. ARK structured its fund to make exposure to private innovative companies available to a broader investor base, including non-accredited investors.
Securitize adds another distribution layer to that model.
Eligible investors can interact with the fund through regulated digital-asset infrastructure, while blockchain technology can support ownership records and other parts of administration.
Those changes can make access easier.
But access and exit are two different financial problems.
An investor being able to acquire exposure to OpenAI through a tokenized fund does not mean that investor will be able to sell that exposure whenever desired.
That distinction becomes especially important as the tokenization industry moves into private equity, private credit, real estate and other assets where limited liquidity is not an accident.
It is part of how those markets work.
Private Markets Put Tokenization’s Limits in Plain View
Tokenization can remove genuine friction from financial markets.
Ownership records can become more programmable. Settlement infrastructure can improve. Products can reach new distribution channels. Assets that previously lived inside isolated databases can interact with blockchain-based financial infrastructure.
None of that is trivial.
But some financial constraints are not infrastructure problems.
A private company may be difficult to sell because there are relatively few potential buyers, because transfers are restricted or because investors disagree about its valuation.
Changing the database that records ownership does not resolve those conditions.
This is why tokenization should not be treated as synonymous with liquidity.
An asset can be digital but restricted.
It can be transferable but rarely traded.
It can even trade and still lack enough market depth for investors to exit large positions efficiently.
The blockchain addresses only part of that chain.
The Next Tokenization Test Is Whether Markets Follow the Assets
ARK’s move is therefore useful for understanding where the industry may go next.
Tokenization has already demonstrated that traditional financial assets can be represented on public blockchains. The next challenge is determining what happens when increasingly complex and less liquid investments move there.
Putting them on-chain is one step.
Building markets around them is another.
For products backed by private assets, that second step may prove considerably harder because it depends on participants, pricing and demand rather than software alone.
ARK has now moved a venture fund with exposure to some of the world’s most sought-after private companies onto blockchain infrastructure.
That expands what can exist on-chain.
It does not guarantee that investors will always find someone willing to take it off their hands.
Tokenization can create a digital asset. Only a market can create a buyer.
