What is the maximum amount you can borrow from Kickstarter?

I'm curious, what's the ceiling on the amount of funding one can potentially secure through Kickstarter? Is there a specific dollar limit that backers are allowed to pledge towards a project, or is it more of a case-by-case basis determined by the project's popularity and appeal? As a platform designed to support creative endeavors and innovative ideas, I'm interested in understanding the financial boundaries Kickstarter imposes on its users.
