ByteDance finds itself at a pivotal juncture where its rapid expansion collides with shrinking margins. As China's premier tech giant, the company saw its first-half revenue surge to a level nearly matching Meta's, but the heavy financial commitment to artificial intelligence is taking a visible toll on its bottom line.

According to three sources cited by The Information, ByteDance's net profit for the first half of this year fell by a single-digit percentage year-over-year to approximately $20 billion. During the same period, revenue climbed about 30% to hit roughly $120 billion. For comparison, Meta also posted a 30% revenue increase in the first half, reaching $117 billion, putting the two companies on nearly equal footing in terms of sales. However, their market valuations tell a different story, with Meta hovering around $1.7 trillion while ByteDance is estimated at $630 billion by secondary market tracker CapLight.

The key factor behind the profit decline is the sharp escalation in AI expenditures. ByteDance recently finalized a $30 billion bank loan, the largest in its history, with a portion of those funds earmarked to support its ever-expanding AI infrastructure. Meanwhile, following the restructuring of its data security architecture in the United States in January, TikTok has been accelerating its e-commerce initiatives, providing a significant boost to overall revenue growth.

Revenue Momentum Picks Up, with TikTok's Global Contributions Rising

The roughly 30% revenue growth in the first half marks a slight acceleration compared to the pace of the past two years. Sources indicate that the company's full-year revenue for last year grew 29% to about $200 billion, with a similar trajectory expected in 2024, while net profit rose 27% to $42 billion in the prior year.

The share of overseas revenue is steadily climbing. A source revealed that international markets accounted for more than 30% of ByteDance's total revenue in the first half, predominantly driven by TikTok. This compares to just 25% in 2024, with forecasts suggesting the full-year figure for 2025 will hold steady around 30%. While Douyin remains the single largest revenue contributor, TikTok's weight within the overall revenue mix continues to expand.

In January, ByteDance sold an 80% stake in TikTok's US data security operations to an American holding joint venture while retaining control of the app's revenue-generating activities. Following that structural shift, as previously reported by The Information, TikTok has ramped up efforts to grow its e-commerce presence in the US, rolling out new programs to attract established brands to TikTok Shop.

AI Investments Dent Profitability, While a Massive Loan Fuels Expansion

AI spending is the direct culprit behind the current margin pressure. ByteDance is developing its own large language models and video generation models, with its Doubao AI assistant ranking among China's most popular mobile AI applications. Its Seedance video model holds a leading position in the global AI video market. Additionally, the company is aggressively pushing into AI cloud services, selling its proprietary models to enterprise clients.

On the chip front, ByteDance is both securing access to existing advanced semiconductors and, as reported by The Information in May, developing its own custom chips for AI model inference. To fund these initiatives, the company secured that $30 billion bank loan, marking the largest single financing round in its corporate history.

On the commercialization side, ByteDance launched Doubao Work, an AI assistant tailored for professionals, in June with paid subscription tiers. The company is also banking on the commercial traction of its Seedance video model to generate additional revenue for its AI business and cloud platform.

Fierce Domestic AI Rivalry, ByteDance Stays the Course with In-House Development

ByteDance faces intense competitive pressure in the AI arena from domestic rivals. In recent months, companies like Moonshot, Alibaba, Z.ai (Zhipu AI), and DeepSeek have released open-source models that approach frontier capabilities in coding and agent tasks at a fraction of the cost of leading US models, quickly gaining global attention. ByteDance, by contrast, has fallen somewhat behind in this race.

Acknowledging the gap, founder Zhang Yiming made his stance clear during an internal meeting in July: the company will not resort to "distillation"—a technique that involves training its models on outputs from US frontier models—even if it means temporarily lagging domestic competitors.

ByteDance is also the only major Chinese model developer that keeps the vast majority of its models closed-source, providing access to enterprise clients primarily through its own cloud platform.

Meanwhile, domestic competitors are accelerating fundraising efforts to bet big on AI: Alibaba is seeking to raise roughly $10 billion through a large-scale share placement for AI infrastructure, while Z.ai (Zhipu AI) kicked off a $5 billion equity and convertible bond issuance plan this week.
