Major New Entrants from 2012 Onward

  • Founders like Evan Spiegel, Bobby Murphy (Snapchat), Travis Kalanick, Garrett Camp (Uber), and Brian Chesky, Joe Gebbia, Nathan Blecharczyk (Airbnb) all became billionaires post-2012  .

  • More recently, AI-boom entrepreneurs such as Alexandr Wang (Scale AI, billionaire by 2021) and others at AI startups like Anthropic joined the ranks  .


Rough Estimate


Combining the data and typical patterns:

  • Base idea: If there were roughly 200–250 billionaires in Silicon Valley around 2012, and there are ~380 in 2025, that suggests at least 130–180 new billionaires over that period.

  • Confirmed high-profile cases: Names listed above add further evidence of numerous new additions, especially from tech booms (social media, AI, mobility).
