That market cap system is outdated and proven to basically be wrong. sorry.
Good news is depending on the system of calculation you choose it could be higher. (or slightly lower if you choose the more typical calculation system)
I know there's other (possibly) more accurate market cap numbers out there. There's plenty of different ways of calculating that number. I think market price is likely the best way. List price can give inflated numbers due to the fact any card can be listed for any amount. Its what cards actually sell for that's the most important.
