From what I understand, we have created small amounts of antimatter, atoms at a time.
I don't think too many organizations have the funds to create it in large ammounts though.

How much does it cost to produce antimatter?
If we count on the production CERN has done over the last 10 years (about 1 billionth of a gram), it has cost a few hundred millions euros.
