No. No, it is not. 1/2 cup is less than 2/3 cup, and if you thought otherwise, welcome to the club — we meet in my kitchen, staring at measuring cups, confused.
Think of it this way: if a half cup were a person, they’d be the one who always says, “I’ll have a small salad,” while 2/3 cup is the friend who orders the extra-large nachos and shares them with the table. One is clearly bigger.

Here’s where we get our hands dirty — but not with dough, just with numbers. A 1/2 cup is exactly 50% of a full cup. A 2/3 cup is about 66.7% of a full cup. That’s a 16.7% difference, which in the world of baking is enough to turn your fluffy cake into a hockey puck.
If you need a visual, imagine a pizza cut into six slices. 1/2 cup is three slices. 2/3 cup is four slices. You’d never hand a friend three slices and say, “That’s more than four,” unless you’re both terrible at pizza math and friendship.
