What is Sam Altman's net worth? Fortune explored after Katie Miller calls him "a thief who stole a non-profit"

Katie Miller has now once again called out Sam Altman for allegedly seeking to enrich himself. Her statement comes a day after an article was published by The Wall Street Journal. In the article, written by Peggy Noonan, she proclaimed Sam Altman to be neither Oppenheimer nor a scientist on whose shoulders the future of humanity seemingly rested. Katie Miller has long been critical of Sam Altman, who has a net worth of $3.2 billion, as per Forbes. In her post, she slammed the OpenAI founder and claimed that he was not a visionary tech leader. Sam Altman, who does not have direct equity in OpenAI, has built his substantial net worth through his massive personal portfolio, spanning over 400 startup and technology investments.
