On October 19, Pump.fun launched PreStocks trading, giving users access to tokens that track the valuations of major private companies. The initial lineup includes OpenAI, Anthropic, Anduril, Neuralink, Figure AI, Kalshi, Polymarket and Oura. Users can trade these tokens directly or launch memecoins paired with them.
PreStocks are synthetic instruments, meaning holders gain exposure to price movements without owning shares, exercising voting rights or receiving dividends. None of the companies involved issued or authorized the tokens. The product is unavailable to U.S. residents.
A Memecoin Built on Another Speculative Bet
A memecoin paired with PreStocks adds another layer of speculation to a token that already tracks the estimated value of a company with no publicly traded shares. Funding rounds, secondary-market transactions and broker estimates provide reference points, but the gap between a token's price and the company's underlying valuation can be substantial.
Buyers are unlikely to be betting on OpenAI's revenue growth. Instead, the platform is capitalizing on the attention these big names attract, not offering genuine access to their shares. News of a funding round or a major contract can move both the PreStocks token and the memecoins paired with it.
Pump.fun's native token, PUMP, edged higher following the announcement. At the time of publication, it was trading at $0.004445.
Layered Risks and Unclear Backing
A position carries two layers of price risk. If a memecoin falls 20% against PreStocks while the PreStocks token itself loses 20% of its dollar value, the combined loss reaches 36% before fees.
According to Bitquery, the transfer fee on OpenAI and Anthropic tokens has been 1% since October 5, down from 5%. That puts the cost of a full buy-and-sell round trip at roughly 2%, assuming the same fee applies to both transfers. Traders should still check the current rates before entering a position.
Liquidity presents another problem. According to a DL News investigation, a holder of Anthropic PreStocks sitting on nearly $1.5 million in unrealized profits could sell only about 950 of their 2,593 tokens through aggregators, and even then at a 34% discount. Those figures date back to April, but they illustrate an important distinction: round-the-clock trading does not guarantee enough liquidity to exit a large position at a reasonable price.
What actually backs these tokens remains unclear. BlockOffice's review of Anthropic PreStocks does not constitute a full audit, disclose the chain of ownership of the underlying assets or establish that Anthropic authorized the arrangement.
Both OpenAI and Anthropic have previously warned that unauthorized transfers of equity stakes may be declared void. That creates another risk: problems involving an intermediary could undermine the token's value regardless of how well the underlying company performs.
Pump.fun's Troubled Track Record
Pump.fun stands to benefit from the additional trading activity, as do token creators who manage to cash out before prices collapse. Trading generates fees for the platform even when buyers lose money.
According to a Sandmark investigation, Pump.fun laid off employees in late March and early April 2026, roughly two months before 25% of their PUMP token allocations were scheduled to unlock. Their unvested tokens were subsequently canceled, with at least one employee reportedly losing tokens worth more than $1 million.
Co-founder Noah Tweedale attributed the layoffs to overly rapid growth, but the company has yet to publicly address the substance of the allegations. Separately, on August 31, a court allowed some of the RICO claims brought by users to proceed.
A Stark Contrast With the SEC's Approach
The launch comes amid a significant regulatory shift. On September 17, the SEC introduced a five-year innovation exemption for tokenized stocks. Under the framework, tokens traded on licensed platforms must carry the same rights as traditional shares, including voting rights and dividends.

Synthetic products that offer price exposure without shareholder rights fall outside the exemption. The framework is also temporary, imposes limits on the number of eligible stocks and trading volume, and allows public companies to object to the tokenization of their shares.
The comparison with PreStocks requires some caution. The exemption concerns shares of publicly traded companies, while OpenAI and Anthropic remain private. Even so, the difference in how investor rights are treated is striking. The SEC's framework requires tokenized shares to preserve shareholder rights. Pump.fun, by contrast, offers non-U.S. traders a fast-moving speculative market without those rights.
Our Take on PreStocks
Demand for exposure to OpenAI, Anthropic and other high-profile private companies is enormous, and Pump.fun has found a way to capitalize on it. But buyers are not acquiring a stake in any of these businesses, and the companies themselves have not authorized the tokens.
Instead, traders are making a speculative bet tied to opaque private-company valuations, with memecoin volatility, trading fees and liquidity risks adding further uncertainty. The proposition looks highly questionable.
For the broader tokenization market, the implications are mixed. Growing interest in such products points to genuine demand, but association with a platform known for speculative price spikes and crashes could discourage companies and institutional partners from getting involved.
As regulators push for tokenized securities to carry genuine shareholder rights, PreStocks remain a way to speculate on the attention surrounding private companies, not a way to invest in the companies themselves.
