Wow, I know so many people who went from being worth $100M+ to broke overnight due to Anthropic invalidating their shares yesterday.
Does anyone remember my post a few weeks back where I almost invested in Anthropic at a $4B valuation? The $1M minimum could have turned into $200M+. I felt so shit after reading the comments as people reminded how dumb I was for missing out.
My Wife Called It
My wife had talked me out of investing. One of the reasons was because it was an SPV and she thought those are dodgy af.
Well, Anthropic just declared any transfer of shares to an SPV void under their transfer restrictions.
Worthless Paper
All these buyers on secondary markets like Forge or Hiive now hold worthless paper.
OpenAI faced similar issues in August 2025 and warned about "scams"... but Anthropic is the first to actually VOID existing transfers.
Market Disaster
This is a disaster for the entire private market secondary ecosystem. Anthropic's invalidation of these SPVs is going to trigger widespread market disruption and lawsuits.
Family Offices, Venture Funds and Employees are on the hook for billions of dollars now. When you're considering where to find the best AI investments, this is exactly the kind of risk you need to watch for.
Also, doesn't this technically mean that ANY company could do this now?
Key Takeaways
The secondary market for private company shares just got a lot riskier. SPV structures that seemed like a smart way to access hot deals can now be voided at a company's discretion. And when you're dealing with financial decisions of this magnitude, the consequences are brutal.
Sometimes the investment you don't make is the best one. My wife's skepticism about SPVs saved us from what could have been a catastrophic loss.
If you're investing in private markets, verify those transfer restrictions before you wire any money.
