How much is the NYSE?

Excuse me, as a cryptocurrency and finance practitioner, I'm often asked about various market valuations. However, I'm slightly confused by the question, "How much is the NYSE?" The New York Stock Exchange (NYSE) is a physical exchange that facilitates the trading of stocks and other financial instruments, not a tangible asset that can be valued at a specific dollar amount. Perhaps you're inquiring about the market capitalization of companies listed on the NYSE? Or are you referring to the trading volume or overall value of transactions conducted on the NYSE? Clarifying the question would help me provide a more precise answer.
