PhysicsWallah, India's leading ed-tech unicorn, is preparing for an IPO in 2025, aiming to raise between $400 million and $500 million. After raising $210 million in September, which valued the company at $2.8 billion, PhysicsWallah has now selected four investment banks to advise on the IPO. The chosen banks include Axis Capital, Kotak Mahindra Capital, Goldman Sachs, and JP Morgan. The listing could make PhysicsWallah the first Indian ed-tech firm to go public
