Why Are Longer-Dated Options Typically More Expensive than Short-Dated Options for the Same Strike?

Longer-dated options have a greater extrinsic value, primarily time value, because there is more time for the underlying asset's price to move favorably before expiration. This increased probability of a significant price change justifies a higher premium.

They offer more flexibility and a lower rate of theta decay, which investors are willing to pay for.
