Executive Snapshot
Brock Purdy's May 2025 extension is worth $265 million over five years at a $53 million average, with $100 million fully guaranteed at signing — 37.7 percent of the total, one of the lower at-signing shares among the current quarterback class. Read on that number alone it is an unremarkable deal for a player of his standing.
Two features make it worth a page. The first is a full no-trade clause running the life of the contract, the first ever granted by San Francisco to a franchise quarterback, and reportedly pushed for by his representation rather than offered. The second is a vesting calendar keyed to April 1 rather than the fifth day of the league year, which is the league convention. Both are departures from house practice and both were obtained by a player drafted with the final pick of his class.
The April 1 Calendar
| Date | What converts | Amount |
|---|---|---|
| At signing (May 2025) | Fully guaranteed at execution | $100M |
| At signing | 2027 salary tranche fully guaranteed | $11.904M |
| April 1, 2026 — passed | Balance of 2027 salary plus the 2027 option converts from conditional to fully guaranteed | ~$27.2M (option reported at $15M and $15.3M) |
| April 1, 2027 — next live trigger | 2028 salary fully guaranteed; 2028 option bonus converts from injury-guaranteed to fully guaranteed | $55.05M salary + $20M option |
| 2032 | Void year: void base salary plus prorated option bonus | $4M proration |
The next date on this contract is April 1, 2027, and it is a large one: roughly $75 million converts on a single morning. A club evaluating a quarterback in March 2027 is not making a football decision in isolation; it is making a $75 million decision with a deadline. That asymmetry is the point of the structure, and it is why the Institute regards trigger-date proximity as a more useful predictor of roster moves than performance data in the weeks before a vesting date.
The Clause and the Guarantee Trade
Purdy's representation pushed for the no-trade clause and a favorable guarantee structure in negotiation, and Purdy has said publicly that he would have signed without the clause. Whether that candor cost anything is unknowable, but the clause is in the document and San Francisco had never granted one at the position before.
The at-signing guarantee of 37.7 percent is the price. A quarterback holding a no-trade clause and $100 million locked has a different risk profile from one holding no clause and $130 million locked, and reasonable representation could argue for either. What is not reasonable is describing the deal by its $265 million headline, which assumes every trigger converts and every option is exercised. Multiple outlets have noted San Francisco can exit after 2026 at minimal penalty.
The trackers disagree on the total guarantee: Spotrac carries $182.55 million, NFL.com reported $181 million at signing. The Institute reports both.
Off the Field
Endorsements. No named-outlet figure. This page does not estimate one.
Foundation. No eponymous filing entity was located. Organizations with the surname Purdy appear in IRS records and are unrelated to the player; they should not be attributed to him.
Tax. California's top marginal individual rate of 13.3 percent is the heaviest home-state burden in professional football. On a $53 million average, the differential against a no-tax state is worth more per year than most players earn in a career, and it is the reason California clubs consistently pay a higher gross for the same net.
