Kingsoft Cloud Holdings Ltd (KC) experienced a significant surge in its stock price, soaring 8.00% in the 24-hour period ending Sunday evening. This remarkable upward movement comes in the wake of news that China's Ministry of Commerce has adopted the WPS format for official announcements, showcasing the growing influence of Kingsoft's software products.

The catalyst for this stock movement appears to be an announcement from China's Ministry of Commerce on October 9, 2025. The ministry issued Announcement No. 61 of 2025, implementing export controls on certain overseas rare earth-related items. What caught the market's attention was not just the content of the announcement, but the format in which it was published - WPS, the office software independently developed by Kingsoft Office, a subsidiary of KINGSOFT group.

This development highlights the increasing prominence of Kingsoft's software solutions in official circles. According to Kingsoft Office's 2024 financial report, WPS Office's global monthly active devices (MAD) had already exceeded 632 million, marking a 6.22% year-over-year growth. The use of WPS format in government communications could further boost these numbers, potentially leading to increased revenue and market share for Kingsoft and its cloud services division. Investors seem to be betting on this positive outlook, driving the stock price of Kingsoft Cloud Holdings Ltd to new heights.
