Cryptocurrency exchange Kraken has signed a multi-season deal with Tottenham Hotspur (commonly known as "Spurs") to become the team's sleeve sponsor. Last week, Kraken announced a similar deal with Spanish team Atletico Madrid, which means the company is now a crypto sponsor of both the English Premier League and Spanish La Liga. Kraken is said to be in talks to raise $100 million by the end of the year for an initial public offering.
