This study takes the designer toy brand Labubu as its research subject, and explores the influence mechanisms of multi-platform online popularity on its market price. By collecting popularity data from Bilibili, Dewu, and Google Trends between May and July 2025, and integrating them with Xianyu secondary market price data, this study applies correlation analysis, multiple linear regression, and the Granger causality test to analyze the dynamic impacts of different communication platforms on price fluctuations. The results show that Google search popularity has a significant positive predictive effect on Labubu's price, indicating that an increase in online attention subsequently drives up market prices. Bilibili popularity is negatively correlated with price, reflecting an obvious time lag between video content production and market responses. Meanwhile, the influence of Dewu platform popularity on price remains relatively limited.
