From the FAQ:

Why does my last transaction not show up in my Pledged funds?
We batch process transactions once daily, so transactions usually take 24~48hrs to appear in the system.

Some of our advertisers only report transaction to us every 2 days, in these rare cases the transaction may take upto 72hrs to appear.
