NBIS stock is experiencing a significant pre-market surge, with reports of gains ranging from over 5% to over 10% or even 11%. The reason for the surge is not entirely clear, but it may be related to the company's strong revenue growth, with a reported 684% jump in Q1 revenue, and its involvement in AI infrastructure. The stock's movement is also possibly linked to its connection with Nvidia, which has reportedly made a significant investment in the company.
