Poker is a game that involves quick decision-making, risk-taking, and bluffing, among other things.
It’s why so many Wall Street investors, from Carl Icahn to David Einhorn, love playing it.
And it’s no different in the highly competitive, risk-taking culture of Silicon Valley.
In fact, some of the top Silicon Valley entrepreneurs and investors are so obsessed with it, they even have their own poker nights almost every month.
Generally, good businessmen are good poker players. It’s no surprise that so many business leaders in Silicon Valley are obsessed with poker.
Chamath Palihapitiya is known as one of the most hardcore poker players in the Valley. He's played in several World Series of Poker events, and finished 101st out of more than 7,000 contestants in 2011.
He also hosts monthly poker nights at his home in Palo Alto, inviting other tech entrepreneurs like David Sacks and Dave Goldberg.
David Sacks has also played in the World Series of Poker, and alongside Palihapitiya, is frequently mentioned as the top poker player in Silicon Valley. In a past interview, Sacks said he doesn't believe in hobbies, but likes to play poker.
He often plays with professional poker player Phil Hellmuth, too. 'I'm not in the same league as (Phil Hellmuth), but I'm not a donkey,' he said in a past interview.
Jason Calacanis isn't afraid to talk about his pokerbobsession, and said in a previous interview that he was 'absolutely addicted' to it at one point. He's a serious poker player and was sponsored by FullTiltPoker when he played in the World Series of Poker for the first time in 2009.

Phil Hellmuth is one of the best professional poker players in the world, so he probably doesn't belong on a list of amateur players. But he lives in Palo Alto and is good friends with a lot of Silicon Valley entrepreneurs. He even gets invited to many private poker games with them.
He told Business Insider that their level of play is so high he was only able to break-even in the first three years playing with them. 'There's a reason these guys made so much money in the real world. Those skills translate to poker,' he said.
With over 30 years of experience in technology, Roger Sippl is a living legend in Silicon Valley.
He's also played in some of the biggest poker games in the world, travelling as far as Macau to play in professional tournaments.
He's been playing poker for a long time, he says. 'I've been playing since I was in my high chair. My grandmother taught me how to play and would deal to me and used to hand out pennies to everyone, but would win them back before dinner,' he told Pokernews.com.
