And yet NKLA still has a $5B market cap despite the entire company being 100% fraud. Amazing. [1] https://finance.yahoo.com/quote/nkla
Tether, either a scam or a criminal money laundering enterprise (or both), has a market cap of over $50B. DOGE, a joke based on an old meme of a Shiba Inu, has a market cap of over $1B.
Not only is the real Tesla's market cap not irrational, at this point I'd say any company that actually has anything of value should be valued in the hundreds of billions. The pizza place around the corner should be at least $100B in that they actually make something.
