On May 11, Anthropic declared every unauthorized secondary transfer of its stock void. OpenAI followed within hours with a substantially similar position. The policy covers SPVs, forward contracts, beneficial interests, and tokenized securities. If your fund is carrying Anthropic exposure that came in through any of those, and your IR team has been telling LPs about it, the issuer is now saying in writing that the transfer never bound the company, and when the issuer's records and your portfolio system disagree about whether a share is yours, the issuer's records are the ones that hold up.
US VC direct secondaries hit $106 billion in 2025, up from $50 billion the year before. Roughly 86 percent of that $106 billion sits in 20 names: Anthropic, OpenAI, SpaceX, ByteDance, and a short list of other AI and frontier-tech companies. On top of the direct market is the SPV layer, which is bigger and growing faster, and 89 percent of GPs expect their SPV deal volume to grow again this year. For the last two years, an LP who wanted AI exposure usually got it through an SPV two or three steps removed from the stock itself, which is exactly the layer the May 11 notice is aimed at.
The word Anthropic chose matters. A voidable transfer is one the company could go challenge later if it wanted to. A void transfer never happened as far as the company's cap table is concerned. Both companies have the cap table, the transfer agent, and the courts on their side.
The assumption every portfolio system makes
Before GoodStream I ran Payability for nine years, and every fund accounting platform, monitoring tool, and LP reporting workflow I saw in that time worked from the same assumption, which is that a signed subscription document equals a position on the issuer's cap table. You sign, you wire, you carry the position, you mark it, you roll it into NAV, and you tell your LPs about the exposure. Nobody goes back to the issuer to confirm the holder, and until this month nobody had a reason to.
Anthropic put that assumption on the front page. Most funds with AI exposure in 2026 got at least some of it through a secondary, an SPV, a forward, or a tokenized wrapper. Those funds are now marking NAV on positions the issuer says never legally happened, and reporting exposure to LPs that may not survive a call to the transfer agent. There is a clawback question sitting underneath that as well, and I doubt many teams have modeled it yet.
What it takes to know what you own
Better fund accounting software doesn't fix this, because the software only knows what somebody typed into it. The fix is tying every position back to what the issuer recognizes, and doing it for the whole book, including the positions nobody is nervous about.
Every position needs to trace to a specific transfer event and a specific issuer acknowledgment, meaning the subscription document on the GP's side plus a confirmation that the issuer or transfer agent recognizes the holder. When an issuer changes policy the way Anthropic just did, you need to find every affected position in hours rather than weeks. And your LP reporting has to separate "position on our books" from "position confirmed by the issuer," because those stopped being the same thing this month, and I wouldn't want to explain the difference to an LPAC after the fact.
This is a documents problem before it is a software problem. The paper that says what a position is standing on, the sub doc, the transfer consent or the absence of one, the SPV operating agreement, is already in the fund's folders, and the work is reading all of it and putting what it says next to what the issuer says. At GoodStream that reading is what we do, with every number tied to the page it came from, so when a position turns out to stop at a sub doc with no issuer consent behind it, you can see that before an LP does.
Anthropic's notice went out on May 11 and OpenAI's went out the same day. Any fund carrying a position in either company should be asking the transfer agent this week whether the issuer agrees that it holds one.
