January 1, 2026, began with the release of December delivery data from China's three major electric vehicle manufacturers: NIO, XPENG, and Li Auto. The numbers tell very different stories and deserve in-depth analysis for investors in this sector.

Those who closely follow the Chinese EV market know just how dynamic and competitive this sector is. Every month, the three manufacturers vie for market share, and the December 2025 data is no exception. What emerges is a varied picture, with some significant surprises that could impact investment strategies in the coming months.

Comparison of December 2025 numbers

The most striking figure concerns NIO , which recorded its all-time monthly record with 48,135 vehicles delivered, marking a 54.6% growth compared to December 2024. This result is particularly significant considering that the Shanghai-based company had to manage the launch of three distinct brands: NIO (premium), ONVO (family), and FIREFLY (premium city cars). Specifically, the NIO brand contributed 31,897 units, ONVO 9,154, and FIREFLY 7,084 vehicles.

Li Auto delivered 44,246 vehicles, a solid result that brings fourth-quarter deliveries to 109,194 units. The Beijing-based company reached a significant milestone in December: 1.5 million vehicles cumulatively delivered since its founding. However, comparing this figure to the 58,513 vehicles delivered in December 2024, a 24.4% year-on-year decline emerges, a point that warrants attention.

XPENG closed the month with 37,508 deliveries, recording a modest 2% growth compared to December 2024. This figure may seem modest, but it must be contextualized within an extraordinary year for the Guangzhou-based company, which delivered a total of 429,445 vehicles in 2025, with annual growth of 126% compared to 2024.

NIO: Multi-brand strategy starts to pay off

NIO's performance deserves special attention. Founded by William Li, the company has built an ecosystem across three brands over 2025, each with a distinct positioning. Its flagship brand, NIO, continues to dominate the premium segment, where it maintains a 40% market share among BEVs priced above RMB 300,000 in China. December's record follows an already solid November with 36,275 deliveries, confirming a steady growth trend in the second half of the year.

An interesting fact concerns the All-New ES8 SUV, which has surpassed 40,000 cumulative deliveries, setting the record for the fastest electric vehicle to reach this milestone in the RMB 400,000+ segment in China. This demonstrates that NIO's premium positioning is working, despite competitive pressure in the industry.

The cumulative deliveries figure is particularly significant: NIO is one step closer to the symbolic milestone of one million vehicles delivered. This goal will likely be reached in early January 2026 and will represent a key moment for corporate communications.

Regarding infrastructure, NIO has continued to expand its charging and battery swap network, a key differentiator from its competitors. Its BaaS (Battery as a Service) strategy remains a cornerstone of its business model, although financial data from recent quarters still show compressed margins and significant operating losses.

Li Auto: Monthly decline hides structural growth

Li Auto's data requires a closer look. The 24.4% month-over-month decline may seem alarming at first glance, but it must be considered in context. December 2024 marked an exceptional peak for the company, driven by aggressive promotions and the launch of new models. The year-over-year comparison is therefore particularly unfavorable.

Li Auto remains a financially solid company. In 2024, it posted revenues of RMB 144.5 billion and a net profit of RMB 8 billion, figures that clearly distinguish it from its still loss-making competitors. Its vehicle margin, although down from 22.7% to 19.7% in Q4 2024, remains among the highest in the industry.

In December, the company also announced international expansion with the introduction of the L9, L7, and L6 models in Egypt, Kazakhstan, and Azerbaijan, marking its first steps into markets outside of China. This geographic diversification strategy could prove important in the medium to long term, especially considering the growing saturation of the domestic market.

The company also launched the "Livis" AI glasses, a product that demonstrates its desire to expand the ecosystem beyond vehicles. This diversification echoes the strategy of other tech-focused manufacturers like Tesla with its side projects.

XPENG: A turning point despite a lukewarm December

XPENG is perhaps the most interesting case study. The December 2025 figure, with only 2% year-over-year growth, might seem disappointing. But this number must be placed in a broader context: the Guangzhou-based company closed 2025 with 429,445 vehicles delivered, more than doubling volumes from 190,068 in 2024 (+126%).

This means that XPENG has built its growth over the previous months, with a steady progression that saw the peak of competition concentrated in the first half of the year. The slowdown in December could indicate a normalization of production rates after a year of aggressive expansion.

A distinctive element of XPENG's strategy is international expansion. In 2025, the company delivered 45,008 vehicles to overseas markets, a 96% year-over-year increase, expanding its presence to 60 countries and regions. This geographic diversification represents an important resilience factor in the event of a domestic market slowdown.

On the sustainability front, XPENG announced that vehicles delivered in 2025 will reduce greenhouse gas emissions by over 6.61 million tons over their life cycle, equivalent to the carbon absorption of 110 million young trees over 10 years. This figure underscores the company's commitment to ESG, which is increasingly relevant for institutional investors.

Considerations for investors

Analysis of the December 2025 data offers interesting insights for investors in these stocks. Each company has a distinct risk-return profile that deserves to be evaluated based on the investor's time horizon and risk tolerance.

For short-term investors, volatility remains high. Chinese stocks are subject to macroeconomic factors (government policies, geopolitical tensions, currency dynamics) that can generate significant movements regardless of corporate fundamentals. December's data could trigger mixed reactions: positive for NIO, neutral for XPENG, potentially negative for Li Auto.

In the medium term (6-12 months), it will be crucial to monitor margin developments and the ability to maintain growth rates. NIO will need to demonstrate that its multi-brand strategy can generate economies of scale. XPENG will need to confirm its 2025 trajectory. Li Auto will need to manage the transition to fully electric vehicles while maintaining profitability.

In the long term , the Chinese EV market remains one of the most promising in the world. Electric vehicle penetration in China continues to grow, and the three manufacturers are well-positioned to benefit. However, competition is fierce, and the ability to differentiate through technology, services, and branding will be crucial.

The overall market picture

The December 2025 data confirms some structural trends in the Chinese EV market. Competition is intensifying not only between the three players analyzed, but also with traditional manufacturers accelerating the electric transition and new entrants seeking to carve out a niche.

The price war that began in 2023 has had lasting effects on margins across the industry. Li Auto has managed to maintain positive profitability, but margins are declining. NIO and XPENG continue to operate at a loss, betting on future growth to reach breakeven.

International expansion emerges as a key theme for 2026. All three companies are investing in building a presence outside of China, but they must contend with European tariffs (up to 38% on Chinese vehicles) and trade tensions with the United States. Emerging markets (the Middle East, Southeast Asia, and Latin America) represent an opportunity, but require significant investments in infrastructure and sales networks.

On the technology front, autonomous driving remains a key differentiator. XPENG has made its XNGP technology a standout, while NIO is developing its own NAD system. Li Auto recently announced OTA updates with advanced NOA features. The race to Level 4 autonomy is in full swing, and whoever manages to offer the best experience could gain a significant competitive advantage.

In conclusion, the December 2025 numbers tell three different but interconnected stories. NIO is reaping the rewards of a bold strategy, XPENG has consolidated exceptional growth, and Li Auto is navigating a transition phase. For investors, the challenge is to distinguish signals from noise and build a fundamentally long-term view, without being distracted by short-term volatility.
