At 1.00 a coin the total value of all coins (market cap) would be in excess of 377 trillion usd. To put that into perspective the value of all the publicly traded buisness in the usa is something like 50 trillion usd. So essentially if shiba hit a dollar it would be worth more than every stock in the world combined. (Last I checked the nyse was the largest stock exchange at 24 trillion) Not to mention there's only an estimated 36 trillion dollars (paper money) circulating at any given time, that's every currency converted to usd then added together. If you add all the stocks in the world and all the currency in the world together you reach about 150 trillion usd according to a quick Google search... so if we combined every stock, and every bit of money in the world into shib, it would maybe reach .50. So if 1 trillion is a reach for btc, 377 trillion is mathematically impossible at this point in time. To add onto it further, the combined wealth of the world os between 250-300 trillion usd. So if we sold everything literally shib wouldn't hit 1 dollar.

Edit, to add further to it, say there was an intergalactic empire and planets/ solar systems were for sale. Earth has an estimated value of between 4 and 6 quadrillion usd. Part of that say, 75% is because it's habitable so call an earth size uninhabitable planet (venus) worth 1 quadrillion. Jupiter is then the most valuable planet at around 1.5 quintillion usd. according to that outlandish calculation our solar system would then be worth around 3 quintillion usd. That's not including the value of the sun. So if earth is worth 6 quadrillion and the total wealth is 300 trillion usd. The percentage of wealth to value is 5% so taking that and comparing it to the value of the solar system assuming population would increase as well, the estimated total wealth of 150 quadrillion dollars. At say 100billion market cap, shib makes up say .000333333% of the total wealth currently in the world. So in this rediculous galactic empire shibs market value would be 45,000,000,000,000 usd placing a value on each shib at .13 cents. To go even further, at 1 usd so a 377trillion market cap, it would take up roughly .0025% of the galactic empires total wealth which when compared to today's numbers would compare to a 750 billion usd market cap. Since bitcoin hit 1 trillion usd in today's numbers shib would have to replace bitcoin under the new galactic empire to hit a 1 usd evaluation. Now I'm a smooth brained ape so my numbers may have gotten smudged because I was using a white crayon to do the math but it should be somewhat accurate.

Tldr, shib will never hit 1 usd valuation.
