Robinhood's stock surged by 7% after the company launched its first credit card, which offers 3% cash back on all purchases. The card is made of 10 karat gold and targets US consumers. CEO Vlad Tenev highlighted the card's rewards and design aesthetic, with some users expressing concerns over the card's appearance. The credit card is part of Robinhood's major push into the credit card market, aiming to compete with established players like Apple. The card is only available to Robinhood Gold subscribers who pay a monthly or yearly membership fee.
