The Tezos Foundation is an independent Swiss-based non-profit organization responsible for the development and promotion of the Tezos blockchain. The Foundation's net worth is estimated to be around $500 million, which is significantly higher than the market capitalization of the Tezos cryptocurrency, which is currently around $1.2 billion. This is because the Foundation holds a large amount of XTZ tokens, which are used to power the Tezos network, and it also has a large amount of funds available to invest in projects that promote the development of the Tezos blockchain. The Foundation also has a large number of partnerships with various companies and organizations, which helps to increase its net worth.
