Private-market secondary transactions can offer access to AI companies before an exit, but buying existing shares is different from investing in a new financing round. The company may receive no new capital, and the buyer’s rights depend on the specific security and transfer process.

Verify what security you are buying

Common shares, preferred shares and interests in a special-purpose vehicle can have different economic and governance rights. Review the actual instrument rather than relying on a headline company valuation.

Understand transfer restrictions

Private companies often have rights of first refusal, board approval requirements or contractual restrictions on transfers. A transaction is not complete simply because a buyer and seller agree on price.

Reconcile the valuation

Compare the secondary price with the latest primary financing, but account for security class, liquidation preferences and time since the round. A discount to the last round does not automatically mean the shares are cheap.

Model dilution

Future fundraising and employee option pools can reduce ownership percentage. Understand fully diluted capitalization and whether the security has any protection.

Evaluate the company, not the hype

For AI startups, review retention, revenue quality, gross margin, compute costs, model dependency and defensibility. Our AI startup valuation framework provides a starting point.

Liquidity can take years

There may be no reliable market for resale. IPOs and acquisitions are uncertain, so investors should not treat private secondary shares like liquid public stock.

Information rights may be limited

Secondary buyers may receive less company information than primary institutional investors. Determine what financial and operational data is available before relying on seller materials.

Secondary shares can be useful when price, rights and company quality align, but they require security-level diligence. The investment is not merely a bet on an AI brand; it is a purchase of a specific private asset with specific restrictions.
