HONG KONG, Nov 3 (Reuters) - Chinese autonomous driving

firm Pony AI is set to price its Hong Kong listing at

HK$139 ($17.90) per share, two people with knowledge of the

matter said on Monday.

Pony AI is planning to fully exercise an upsize option by

issuing 6.3 million additional shares to raise a total of HK$6.7

billion ($862 million), said the sources, declining to be named

because the information was confidential.

The offering price would represent a 4.2% discount to Pony

AI's Friday close of $18.68 apiece on Nasdaq.

Pony AI did not respond to Reuters' requests for comment.

Bloomberg first reported the pricing guidance on Sunday

evening.

The company is offering about 42 million shares in the Hong

Kong listing at a maximum price of HK$180 a share, its listing

prospectus showed.

It will price the deal later on Monday and start trading on

the Hong Kong Stock Exchange on November 6.
