People need to stop thinking that (m)any companies do anything for float reasons.
First, as the other replier states, in the Kickstarter case, Amazon is not holding the funds so there is no float.
But let's pretend they do charge your card. And let's further pretend that they hold your funds for 365 days (in actuality they hold it for a few weeks or months). And let's further pretend that they get 1% on that money (money market rates are closer to 0.5%). That would be a rounding error of $1 million.
