Frequently Asked Questions
Everything about the trillion dollar club, from the taxonomy to the members.
What is a Kilocorn?
A Kilocorn is a company or asset valued at $1 trillion or more. The term follows the metric prefix progression in startup nomenclature: Unicorn ($1B), Decacorn ($10B), Hectocorn ($100B), Kilocorn ($1T).
How many Kilocorns are there?
As of May 2026, there are 13 Kilocorns: NVIDIA, Alphabet (Google), Apple, Microsoft, Amazon, TSMC, Broadcom, Saudi Aramco, Tesla, Bitcoin, Meta, Berkshire Hathaway, and Walmart (the newest member). Bitcoin remains the only decentralized Kilocorn.
What is the difference between a unicorn, decacorn, hectocorn, and kilocorn?
Each step scales by a factor of ten. A unicorn is a startup worth $1 billion, a decacorn is worth $10 billion, a hectocorn is worth $100 billion, and a kilocorn is worth $1 trillion. The names use metric prefixes, so a kilocorn is worth a thousand unicorns.
What was the first trillion dollar company?
Apple became the world's first Kilocorn on August 2, 2018, when it reached a $1 trillion market capitalization.
Why is it called Kilocorn?
Kilocorn uses the metric prefix kilo- (one thousand) applied to the unicorn taxonomy popularized by Aileen Lee in 2013. A unicorn is worth $1 billion; a kilocorn is worth a thousand unicorns, or $1 trillion. The progression also includes Decacorn ($10B) and Hectocorn ($100B).
