No Nigerian startup or business is worth 56 billion dollars because we don't have any of such entity that serves the global audience/market.

For an entity to be worth such, it must boast of a global market of consumers.

Now remember that the bid price of an asset/value isn't dependent on its stock value.

So the stock value of Tesla might be about 4 billion dollars but it could be sold for more than that depending on the potentials the buyer sees in it.
