I don&#x27;t have any empirical data, however I believe spot prices wouldn&#x27;t move.  Spot prices tend to be relatively flat except for odd spikes which AWS uses to kick off people who use Spot  as if were the same as Dedicated Instances.  You&#x27;re already getting 75-80% off the Dedicated price, so a 5% reduction isn&#x27;t going to move the needle all that much.
