What is the most number of cups stacked?

As of my last knowledge update in October 2023, the record for the most cups stacked in a single attempt is 1,200 cups, achieved by the team of players known as the "Cup Stacking Team" in 2021. This impressive feat showcases the skill and speed required in the sport of cup stacking, where participants compete to build and deconstruct stacks of plastic cups in the shortest time possible. For the latest records, it's always best to check with official record-keeping organizations like Guinness World Records.
