What does current price/share have to do with value of a stock option? The price/share is what I PAY to acquire the stock ... if I buy it at that strike price and it's valued at that price I have zero net gain. I've had various conversations where people making offers in more mature companies try to correlate my potential stock option grant X price/share as some measure of worth. It's only the gain that matters.
