Elon Musk’s SpaceX has emerged as the world’s most valuable private company, reaching a staggering $1.25 trillion valuation. This follows its merger with xAI, the billionaire’s artificial intelligence venture.
The deal makes SpaceX the most valuable private company in history, overtaking OpenAI, the creator of ChatGPT, whose valuation has also surged to $840 billion after securing the largest investment ever made in a private company, a $110 billion backing from Nvidia, SoftBank, and Amazon.
The findings come from data analysis by BestBrokers, a financial research and analytics platform that tracks global startup valuations.
The firm analysed the latest data from Crunchbase, TechCrunch, and PitchBook to identify which industries are producing the most unicorns, privately held companies valued at over $1 billion, and which regions dominate the landscape.
1,705 unicorns worldwide, half in the United States
As of March 2026, a total of 1,705 startup companies have reached unicorn status globally, with the United States accounting for 881 of them, more than half of the world’s billion-dollar private companies.
Beyond SpaceX and OpenAI, the US hosts several other massively valued private companies, including Anthropic ($380 billion), Stripe ($159 billion), Databricks ($134 billion), and Waymo ($126 billion).
The country’s dominance reflects its deep venture capital ecosystem, world-leading research universities, and major technology hubs like Silicon Valley.
China ranks second with 287 unicorns, led by ByteDance, the parent company of TikTok, valued at $480 billion, and fintech giant Ant Group at $150 billion. India has emerged as another major hub with 85 unicorns, including Reliance Retail ($101 billion) and Reliance Jio ($58 billion).

The United Kingdom leads Europe with 69 unicorns, including fintech leader Revolut ($75 billion) and payments firm Checkout.com ($40 billion). South and Central America host roughly 38 unicorns, with Brazil leading the region with 20 companies.
AI dominates new unicorns created
Artificial intelligence companies account for the largest share of startups that reached unicorn status in 2026. Of the 39 companies that achieved billion-dollar valuations this year, nine operate in the AI sector, representing 23% of the total.
HealthTech ranks second with five companies (13%), whilst semiconductors, cybersecurity, cloud infrastructure, and SpaceTech each produced three new unicorns. Robotics, data analytics, and cryptocurrency each added two companies to the unicorn ranks.
Among startups that first crossed the $1 billion threshold in 2026, Ricursive Intelligence stands out as the most highly valued. The US-based AI company reached a $4 billion valuation in January after raising $300 million in a Series A round led by Lightspeed Venture Partners, just weeks after launching publicly.
The company was founded by former Google DeepMind researchers Anna Goldie and Azalia Mirhoseini.
Other notable 2026 unicorns include Rain, a Bahrain-based cryptocurrency platform valued at $1.9 billion; Bedrock Robotics at $1.8 billion; Pomelo Care, a digital healthcare company at $1.7 billion; and Varda Space Industries at $1.6 billion, which is developing spacecraft designed to manufacture high-value materials in orbit.
SpaceX’s merger with xAI creates a combined entity valued at $1.25 trillion ahead of a planned IPO, a record in private market history. The deal consolidates Musk’s space exploration and artificial intelligence ambitions under one roof.
OpenAI’s $840 billion valuation, while second to SpaceX, still represents extraordinary growth for a company that was relatively unknown outside tech circles just a few years ago. The $110 billion investment from Amazon, Nvidia, and SoftBank is the largest single investment in a private company to date.
The term “unicorn” was introduced in 2013 by venture capitalist Aileen Lee to describe privately held startups valued at over $1 billion, companies so uncommon they seemed almost mythical. At the time, there were only a few dozen worldwide and now, SpaceX is at the top of the list.
Thirteen years later, the landscape has transformed dramatically, with over 1,700 companies now holding billion-dollar valuations.
