This market resolves YES if neither Musk NOR Zuckerberg uses performance enhancing drugs like testosterone for enhancement in their fight. This is based on my subjective belief, not offical tests.

If they used gear extensively in training, but are clean day of, I will still resolve NO.

If something else crazy happens, like a robotic exoskeleton or neuralink implant, this market resolves NO.

If they decide to fight with swords, the market resolves NO.

If there is no fight, the market resolves N/A.

Basically, this is meant to capture the likelihood of the fight being abnormally intense / entertaining because of shenanigans.
