As we enter 2025, the global startup scene is booming. There are now 1,259 private companies worth over $1 billion, known as “unicorns,” with a total value of more than $4.3 trillion. This shows just how strong and innovative the startup world is today.
The biggest news of the year? SpaceX, Elon Musk’s space company, has overtaken ByteDance (the company behind TikTok) as the world’s most valuable startup. After a major share sale in December 2024, SpaceX’s valuation jumped to $350 billion, leaving ByteDance behind at $300 billion.

Here’s what’s happening in the unicorn market:
SpaceX leads the pack
