This descriptive research examines the IPO regulatory frameworks of five key countries: India (SEBI), China (CSRC), Japan (FSA), USA (SEC), and Saudi Arabia (CMA), focusing on regulatory authorities, approval processes, disclosure norms, and recent reforms. The study details SEBI's merit-disclosure hybrid with 2025 float reductions, CSRC's STAR tech waivers, FSA's Growth Market flexibility, SEC's disclosure-based S-1 efficiency, and CMA's SME fast-track. Comparative tables highlight process timelines (1-12 months), public floats (10-30%), and investor protections amid global IPO resurgence. Objectives cover regulatory bodies and frameworks; scope limits to these exchanges; limitations restrict to five countries. Findings reveal convergence toward tech accommodations, enhancing market access while addressing asymmetry.
