Kraken

Kraken is one of the oldest and largest cryptocurrency exchanges in the world, founded in 2011 and launched in 2013 by Jesse Powell after the Mt. Gox security failures convinced him crypto needed an exchange built on trust. Operated by parent company Payward, Inc., Kraken lets retail and institutional clients buy, sell, trade, stake, and self-custody dozens of digital assets, alongside crypto futures, margin, and index products. By late 2025 it served over 5 million funded accounts, held tens of billions in client assets, and was preparing for a public listing.
