Check SPV Transfer Rules Before a Buyer Commits

A buyer can commit before the company says yes

If you are selling vested shares in a private company through an SPV, a single-purpose buying vehicle, the buyer can commit before your company approves the transfer. Anthropic and OpenAI told investors earlier this year that unapproved sales or transfers of their shares would be treated as void.

A buyer commitment leaves the transfer incomplete. The buyer may agree to buy, but the shares still move under the company's rules. If the company did not approve the transfer, the sale can fail after the buyer has already committed.

Run the two checks before money moves

Before any buyer commits, ask two questions. The first asks whether your company allows the transfer. The second asks whether the platform clears the company's right of first refusal, or ROFR, the company's chance to buy the shares first, before the buyer commits.

• Company transfer check: Ask the company for a yes or no on SPV transfers. If the answer is no, stop before the buyer commits.
• Platform ROFR check: Ask the platform for a yes or no on clearing ROFR before commitment. If the answer is no, do not treat the buyer commitment as final.

The first check protects you from a transfer restriction. Many private companies limit who can buy shares and how they can be sold. An SPV is a new buyer, even if it is buying on behalf of investors. A transfer restriction can require company approval, board approval, or a signed agreement from the buyer.

The second check protects you from a platform timing gap. EquityZen resolves a company's right of first refusal before an SPV-based offering is opened to investors. Hiive handles a company's right of first refusal during the transaction instead of clearing it in advance of investor commitment. That difference changes when the sale becomes safe.

A ROFR can look like a simple company option. In practice, it can change who buys your shares. If the company exercises it, you may sell to the company instead of the SPV. If the company declines, the SPV can proceed. The platform's timing determines whether the buyer's commitment is made with that risk already resolved.

The market is moving faster than your paperwork

SPV secondary purchases have grown quickly. SPVs accounted for 7% of private share trades on Forge in 2018 and 64% in early 2025. More SPV activity means more chances for a buyer to commit before the company's approval is in hand.

EDGAR filings show 105 HII-named SPV vehicles since August 2025, covering 76 underlying company names; the 92 vehicles with dollar amounts show $553,035,046 sold and 6,071 investor slots. In the first 11 days of September 2026, nine HII-named SPVs made their first Form D filings with the SEC, while ten such vehicles were formed during August 2026.

From May 2026 through the first 11 days of September 2026, 69 of the 105 HII vehicles first appeared on EDGAR. The pace matters because a faster market can pressure sellers to move before the paperwork is clean.

Keep the record before the buyer commits

Start with the company. The agreement that governs your shares may allow an SPV transfer, require board approval, or leave the company's ROFR unresolved. The company can say yes to the transfer and still exercise its ROFR, so the two answers are not the same. If the answer is no or unclear, pause the sale.

Then ask the platform. It may clear ROFR before investors commit, or handle it during the transaction. The platform's answer tells you whether the buyer is committing before the company's choice is resolved.

Get the answers in writing. A platform page can say ROFR is managed during the transaction. A company email can say the transfer needs approval. Those documents are the record you can show the buyer. If either answer is unclear, pause the sale and get the answer in writing before the buyer commits.
