5 Largest Global IPOs of All Time

4. NTT Mobile (NYSE:NTT)

Total value of the IPO (in billions of dollars): 18.1

Total value of the IPO adjusted for inflation (in billions of dollars): 28.7

NTT is only ranked lower in our list due to its IPO having taken place back in 1998, and remained the largest IPO in Japan for the next two decades. If adjusted for inflation, the communication company would’ve had the largest IPO in history, easily overtaking our top 3 companies.
