From his small office in Singapore, Kelvin Pang is ready to wager a $23 million payday that the worst of the chip shortage is not over for automakers — at least in China.

Pang has bought 62,000 microcontrollers (MCUs), chips that help control a range of functions from car engines and transmissions to electric vehicle power systems and charging, which cost the original buyer $23.80 each in Germany.

He's now looking to sell them to auto suppliers in the Chinese tech hub of Shenzhen for $375 apiece. He says he has turned down offers for $100 each, or $6.2 million for the whole bundle, which is small enough to fit in the back seat of a car and is packed for now in a warehouse in Hong Kong.
