Williams was Twitter’s CEO until 2010, when current CEO Dick Costolo took the helm. Williams is now working on developing a publishing platform, Medium, which is dedicated to long-form content.
Co-founder and chairman Dorsey has a 4.9 percent stake while Costolo holds 1.6 percent. This means their gain from the Twitter IPO could be US$585 million and US$189 million respectively if the company is valued at $20 billion, says Wealth-X.
“Twitter’s IPO announcement confirms that being a self-made entrepreneur is one of the few strategies available for acceleration of becoming a billionaire and adds another notch of success to the New York-based venture capitalists in Silicon Alley,” said Wealth-X president David S. Friedman.
“Twitter’s valuation demonstrates that it truly has become the interest graph. However, it’s still too early to see if its monetization strategies on the advertising side will prove successful.”
Twitter chose TWTR as its ticker symbol, but has not indicated whether it will trade on the New York Stock Exchange or the Nasdaq Stock Market.
Wealth-X, which is headquartered in Singapore, made this announcement today, Oct. 4.
