# American Option ⎊ Definition **Published:** 2026-03-09 **Author:** Greeks.live **Categories:** Definition --- ## American Option An American option is a contract that allows the holder to exercise their right to buy or sell the underlying asset at any time up to and including the expiration date. This flexibility provides more control to the buyer but also introduces complexity for the seller, who may face early assignment. In traditional markets, American options are common for individual stocks, while in crypto, their use is more specific to certain platforms. The ability to exercise early can be valuable if there is a sudden price movement or if the holder wants to capture dividends or other benefits associated with the underlying asset. However, this flexibility typically makes the option more expensive than a comparable European option. Traders must be aware of the exercise style when evaluating the risk and cost of their positions. - [Put Option Premium Cost](https://term.greeks.live/definition/put-option-premium-cost/) - [American Style Option](https://term.greeks.live/definition/american-style-option/) - [Option Greeks Sensitivity](https://term.greeks.live/definition/option-greeks-sensitivity/) - [European Style Option](https://term.greeks.live/definition/european-style-option/) - [Binomial Tree](https://term.greeks.live/definition/binomial-tree/) - [Early Exercise](https://term.greeks.live/definition/early-exercise/) - [Early Exercise Strategy](https://term.greeks.live/definition/early-exercise-strategy/) - [American Style Options](https://term.greeks.live/definition/american-style-options/) ## Glossary ### [American Put Options](https://term.greeks.live/area/american-put-options/) Option ⎊ An American Put Option, within the cryptocurrency derivatives landscape, grants the holder the right, but not the obligation, to sell a specified quantity of an underlying digital asset at a predetermined price (the strike price) on or before a specific expiration date. ## Discover More ### [Zero-Knowledge Option Primitives](https://term.greeks.live/term/zero-knowledge-option-primitives/) ![A complex geometric structure visually represents smart contract composability within decentralized finance DeFi ecosystems.
