The phrasing of the question indicates a possible misunderstanding of electrical current. The pink wire from the ignition switch is part of a circuit that is protected by a 50A fuse under the hood but that doesn't mean that it actually flows anywhere near that much current (or is even capable of flowing that much current). The amount of current flow varies depending on the draw from various components connected to the circuit. Also, that particular wire is in parallel with some others so the current is split between them.
So the question is... what are you trying to accomplish that would lead you to ask that question? If you are planning to add some kind of electrical accessory and want to find a power source, there are far better options than tapping into the ignition wire. The best is to use one of the three extra ports in the dash fuse box that GM put there specifically for adding electrical accessories.
