Answer:
Delaware
Step-by-step explanation:
Actually Delaware has more companies registered there than people living there. Delaware has more than 1,000,000 registered businesses, over 50% of all American corporations, over 75% of IPOs involve companies incorporated in Delaware and over 60% of all Fortune 500 corporations. This means that the trend is increasing and in the future those numbers will only go up.
Two things make Delaware unique:
- bi-partisan consensus on keeping a modern corporate statute
- Delaware's corporate lawyers provide advice in how to achieve this
The combination of the two factors (political and technical skills) have made Delaware's corporation statute one of the most advanced and up-to date. Of course state courts do their part and probably protect corporations more than in any other state.
