Solana-based PreStocks tied to Anthropic and OpenAI posted sharp declines this week after both AI firms warned that unauthorized share transfers conducted through tokenized structures and SPVs may be invalid and carry no shareholder rights. The announcements mark a clear conflict between private-market tokenized instruments and the legal protections afforded to holders of private company equity.
According to CoinGecko, the Anthropic-linked token on Solana-based PreStocks plummeted after the notice, sliding from roughly $1,400 to a low around $812 within a day. OpenAI’s equivalent token also fell to lows near $900 after previously trading above $1,300. The tokens have since rebounded somewhat, with the OpenAI instrument trading above $1,000 in subsequent sessions.
Anthropic PreStocks were trading around $879 at the time of writing, down nearly 32% since late Tuesday, leaving the token with a market capitalization of about $8.4 million. PreStocks are tokenized instruments designed to track the implied value of private firms before a potential public listing, but they are not officially backed by the companies whose shares they reference.
What happened?
In updated transfer policy notices, Anthropic and OpenAI warned buyers that unauthorised equity transactions may not provide any legal ownership over the underlying shares. Anthropic stated that any sale or transfer conducted without board approval is void, meaning buyers would not be recognised as shareholders and would not receive stockholder rights. OpenAI issued a similar warning, saying transfers completed without written consent could be invalidated and carry no economic value to purchasers. The notices also cautioned that unauthorised transactions may violate U.S. securities laws.
The episode centers on SPVs, or special-purpose vehicles, which are commonly used in private secondary markets to pool investor money around shares of privately held companies. Under that structure, the SPV holds the shares while outside investors buy exposure to the vehicle rather than direct ownership of stock. Layered SPV arrangements can create multiple levels of fees and complicate verification that the underlying shares were legally obtained, according to PitchBook analyst Emily Zheng, who spoke to Decrypt. Zheng noted that such structures can obscure whether the transfer was properly authorized in the first place.
Anthropic went further by publishing a list of platforms and firms it described as unauthorized channels for trading its shares. The list included Open Door Partners, Unicorns Exchange, Pachamama, Lionheart Ventures, Sydecar, Upmarket, and new offerings on Forge Global and Hiive. Forge Global’s inclusion drew particular attention because it operates as a regulated secondary marketplace for accredited investors trading private company shares. Earlier reports cited Anthropic’s implied valuation on Forge at about $1 trillion, surpassing OpenAI’s valuation of roughly $880 billion on the same platform, figures later confirmed by Forge CEO Kelly Rodriques.
In the meantime, both companies emphasized that unauthorized tokenized activity remains distinct from company-approved secondary sales. As of publication time, neither OpenAI nor Anthropic has announced enforcement action against token holders.
What drove the move
The immediate catalyst was the public guidance from Anthropic and OpenAI warning that unauthorized equity transfers involving tokenized interests and SPV-based deals may be void and carry no rights or value. The statements underscored a broader issue in private markets: tokenized representations of private equity can create ambiguity around ownership and governance, especially when transfers bypass board-approved channels.
The market reaction reflected those concerns. The most-noted price moves occurred on the Anthropic-linked PreStock, which saw a steep retrenchment after the notices. The OpenAI token also traded with renewed volatility, dipping to multi-hundred-dollar lows before stabilizing somewhat.
Market context and investor implications
The warnings come amid a broader wave of scrutiny over secondary-market tokenization and the vehicles used to distribute exposure to private firms. SPVs are a common conduit for private market access, but they can complicate legal ownership verification and raise questions about the enforceability of transfers in unusual or unauthorized structures.
While the tokens themselves are not official company securities, their price signals reflect investor appetite for synthetic exposure to private AI leaders and the perceived risk of regulatory or legal challenges to tokenized deals. The situation also spotlighted the tension between high-profile private valuations and the accuracy or enforceability of secondary-market pricing in tokenized formats.
Bigger picture
The episode sits at the intersection of private-market liquidity, regulatory risk, and the evolving use of tokenized equity instruments. The unauthorized-transfer warnings come at a time when Forge Global and other platforms have been cited as venues for secondary trading of private shares, with notable mentions of Anthropic and OpenAI in different market contexts. Forge CEO Kelly Rodriques publicly affirmed the indicated valuations on Forge, aligning with earlier reports that placed Anthropic’s implied value around $1 trillion and OpenAI’s at roughly $880 billion on the same platform.
Analysts view the moves as a reminder that tokenized instruments tied to private equity carry material risk if they rely on unapproved transfer channels or unclear ownership trails. The episode could influence how market participants price such instruments and how platforms vet transactions involving private-company equity.
What analysts are saying
Industry observers have pointed to the potential for higher costs and greater opacity in layered SPV structures, which can complicate due diligence and ownership verification. The Decrypt report cited PitchBook’s Emily Zheng, who noted that multi-layer SPVs can create several fee layers and complicate confirmation of legal ownership, a factor that could sour investor sentiment toward tokenized private-market exposure.
Enforcement and next steps
At this stage, neither OpenAI nor Anthropic has announced enforcement action against token holders. The notices emphasize potential legal risk and underscore the need for clarity on what constitutes authorized channels for secondary transactions in private equity. Investors will be watching for any regulatory or platform-level actions that could affect tokenized holdings or the broader use of SPV-based structures in AI-related equities.
Closing: what to watch next
Key developments to monitor include any further guidance or enforcement actions from Anthropic and OpenAI, updates from secondary-market platforms on how they handle tokenized exposure to private shares, and potential changes in pricing dynamics for PreStocks tied to Anthropic and OpenAI. Market participants will also be attentive to any shifts in appetite for private-market risk against the backdrop of ongoing regulatory scrutiny and evolving governance rules for tokenized securities.
As the industry navigates these questions, the next moves in the PreStocks space will hinge on how quickly issuers and platforms can establish clear authorization pathways for transfers and robust verification of underlying ownership, as investors weigh the potential upside of private-market exposure against the risk of invalid transfers and lost rights.
