Weibo Corporation (NASDAQ: WB, HKEX: 9898) saw its stock surge 5.13% in Tuesday's trading session following the release of its better-than-expected third-quarter 2025 financial results. The Chinese social media giant's performance was particularly bolstered by strong growth in advertising revenue from Alibaba and significant non-operating gains.

Despite a 5% year-over-year decrease in overall net revenue to $442.3 million, Weibo's financial report contained several bright spots that impressed investors. Notably, advertising revenue from Alibaba skyrocketed by 112% to $45.5 million, driven by higher local services and e-commerce budgets. This surge helped offset declines in other sectors, particularly in food and beverage, which had benefited from the Paris Olympics in the previous year.

The company's bottom line received a substantial boost from non-operating income. Weibo reported a net income attributable to shareholders of $221.1 million, or $0.83 per diluted share, up significantly from $130.6 million, or $0.50 per share, in the same quarter last year. This increase was largely due to a $117.8 million gain on an equity-method investment and a $39.5 million fair-value gain. Additionally, Weibo maintained a strong financial position with $2.04 billion in cash and short-term investments as of September 30, 2025, generating $200 million from operating activities in the third quarter alone.

Weibo CEO Wang Gaofei highlighted the company's progress in intelligent search and AI applications, stating, "Weibo's intelligent search maintained robust growth in user base and search volume, further meeting user demands and driving overall platform search traffic." This focus on technological advancements, coupled with improvements in content marketing and ad conversion rates, appears to have resonated well with investors, contributing to the stock's positive performance.
