SYDNEY (Reuters) - South Korean gaming company Shift Up is set to price its initial public offering (IPO) at the top end of its price band and raise $313 million, according to a source with direct knowledge of the matter.

Books close this week and pricing is expected to be finalised on Monday, the source said. The source did not want to be identified since they are discussing confidential information.

Shift Up did not have immediate comment when contacted by Reuters.

If finalised, the pricing values the game developer's market capitalisation at 3.5 trillion won ($2.52 billion).

Shift Up's second-largest shareholder is Tencent ( TCTZF ) with a 40% stake, which is expected to shrink to about 35% after the public offering, analysts said.

Tencent ( TCTZF ) did not immediately respond to a request for comment.
