>Commodities like corn have been managing this for a long time… what’s special about chips?

Chips aren't grown, for starters. They require very expensive facilities that take a long time to plan, build and start up. And ag firms are not seeing their stock price skyrocket based on the assumption that they will show exponential revenue growth every quarter, so there's no incentive for them to overbook their capacity and hope for the best. Maybe if the population was doubling every six months, you'd see something similar in corn. Prices in the real world are not perfectly elastic, and big deals are often locked in long before actual production.
