【明報專訊】Alibaba's Ant Group ("Ant") is raising over $267 billion in its simultaneous offerings on the mainland and in Hong Kong, making it the world's largest IPO. Ant combines a payment platform, digital wallet, financial intermediary and lending and insurance services into one, with advantages in big data and artificial intelligence. The market valuation of over $3 trillion by major banks not only reflects that international capital knows no boundaries in its pursuit of profits, but also highlights Hong Kong's role as a window of China. The thresholds for foreign investors in the mainland market allow Hong Kong to continue to play its role for international financing. As long as the mainland is thriving and Hong Kong's uniqueness of "one country, two systems" is maintained, Hong Kong's status as an international financial centre will remain solid.
