ByteDance's net profit for 2025 fell by more than 70% year-over-year, despite a significant increase in revenue, according to insider reports. The company's domestic revenue grew by approximately 20%, while overseas revenue surged nearly 50%, driven primarily by the expansion of TikTok Commerce. The proportion of overseas business rose from about 25% in 2024 to over 30% in 2025. The decline in net profit is attributed to substantial investments in AI technologies, including AI chip procurement and the development of foundational models and infrastructure for AI initiatives like Doubao. These investments, particularly in the third and fourth quarters, have significantly narrowed ByteDance's net profit margins.
