Mega-Round Option Check: Strike vs Dilution

A large round resets your option math

Your startup just raised at a much higher valuation, and your unexercised options now sit against a new price. Fireworks AI disclosed a $1.505 billion Series D at a $17.5 billion valuation on July 15, nine months after its $4 billion Series C. Run a three-number check: compare your strike to the new round price, your last tender or secondary price to the new round price, and your ownership percentage before the round to after the round's pool and dilution.

Fireworks' annualized revenue run rate exceeded $1 billion, compared with a figure above $280 million at the Series C. Daily token volume on its platform rose from 15 trillion to a level above 40 trillion. Atreides Management, Index Ventures, and TCV led the Series D, while existing investors Evantic, Lightspeed Venture Partners, and NVIDIA participated.

The Fireworks example shows the difference between a higher valuation and a payout. A valuation can rise because revenue, usage, and investor demand all move, or because a small group of large investors pays a higher price. For an employee, the useful number is the gap between what you pay for your shares and what the new investors paid. Dilution happens because new shares are issued: if you owned a fixed number of shares before the round, your percentage can fall after the round, even if the company is worth more.

Three numbers show whether the round helped you

Your strike is what you pay to buy shares. Investors paid the round price in the new round. If your strike is below the round price, your options have value at that price. Above the round price, the round may have raised the company's valuation without creating value at your exercise price.

Treat the round price as a reference point for future exercises, while your exit price may come later. A later fair-market-value price, often called the 409A, may move, but it will not simply equal the round price. Repricing is a board decision, not an automatic result of a raise.

A tender or secondary price is the last private sale price for shares. The annual market for selling private-company shares is roughly $30 billion, up 300% over ten years, yet it equals only 2% of the $1.5 trillion value of late-stage venture-backed companies. That price is a useful comparison, but it does not guarantee a sale. A last secondary price far below the new round price may mean the round is moving on investor demand rather than on a wide buyer base.

Run the check before you exercise

Use this checklist after a large round. Each item should take only a moment if you have your grant letter, cap table summary (the ownership breakdown), plan administrator contact, or a recent valuation document. The first three items are the three-number check; the fourth catches the pool; the fifth turns the result into a decision.

• Compare your strike to the new round price. Below the round price means your options have value at that price. Above it means the round did not create value at that price.
• Compare your last tender or secondary price to the new round price. A large jump can signal investor demand. A small jump can mean the round price is a negotiated reference point with a narrower buyer base.
• Check your ownership percentage before and after the round. New money, new investors, and any expanded option pool can reduce your percentage even if the company value rises.
• Ask whether the option pool was increased before the round. Startups commonly set aside 10% to 15% of company ownership for employee option pools. A pre-round pool expansion can dilute you more than the new investors do.
• Ask for the post-round 409A and the exercise window. The exercise window tells you how long you have to act, especially after leaving.

When the answers are unclear, ask your plan administrator for the post-round cap table summary and the 409A date.
