Common usage–abetted by Merriam-Webster–notwithstanding, “centi-” is the System International (essentially the US Metric System) prefix for “divided by 100”, and has been for at least 6 decades, and hence is incorrectly used here; “centibillionare” actually means “has 1/100 of $1B”. The correct term is “hectobillionaire”.
I read the title wrong so at first I was like “That’s gotta be a really long list”, followed by “even I am a centimillionaire”
