Mark Zuckerberg lost $5.9 billion on Facebook's initial public offering. Shareholders lost billions of their own.
But there was one group of people that befitted from Facebook going public: Menlo Park homeowners.
Real estate site Zillow put together an infographic that shows how the real estate market has ballooned during the three month lead up to Facebook's IPO last month.
The study shows that the number of listings for million dollar homes in the city nearly doubled ahead of the IPO.
Zillow also said that median Silicon Valley home values are up 15 times over the median U.S. home value.
The graphic also looks at neighboring cities and how they fared when other tech companies went public, such as Yelp, LinkedIn and Zynga.
