1. Strong December Sales, But Mixed Full-Year Performance
Tesla China’s December 2025 wholesale figures of 97,171 vehicles represent one of its highest monthly totals on record, and year-on-year retail sales were also reported as positive, growing around 13 per cent in December. This suggests a meaningful year-end rebound in demand and supports the view that Tesla’s Chinese operations retain resilience in a highly competitive market.
However, over the full year, China shipments declined by about 7 per cent compared with 2024, and gains were concentrated in only a few months. This has led to Tesla being overtaken by domestic rival BYD as the world’s largest EV seller in 2025, reflecting intensifying competition particularly at the more affordable end of the market.
The stock’s reaction (a more than 3 per cent gain on strong China sales) underscores how much investor sentiment is tied to China as Tesla’s largest addressable EV market. Robust December figures provided reassurance, even though broader annual trends remain challenging.
2. China Is Critical, but Not Sufficient on Its Own
China is, and will remain, strategically crucial for Tesla’s growth for three main reasons:
It remains the largest EV market in the world, with structural growth and supportive infrastructure.
Tesla’s Shanghai Gigafactory is a major export hub as well as a domestic production centre, giving it operational flexibility.
Strong delivery months can help balance out slower periods and justify positive earnings revisions.
However, recovery in China alone may not restore Tesla’s global momentum. The company’s annual sales in key regions such as North America and Europe have faced headwinds, partly driven by price competition and policy changes such as the expiry of federal EV tax credits in the US.
3. Full Self-Driving (FSD): A Future Growth Lever
Approval and widespread deployment of FSD could materially reshape Tesla’s revenue profile. Regulatory filings indicate that Tesla expects full approval of its FSD software in China sometime in early 2026, which would allow broader commercial use of the technology beyond the current partial approval stage.
The significance of FSD to Tesla’s future strategy is multi-fold:
Differentiated product offering: If FSD achieves high reliability and regulatory acceptance, it could enhance Tesla’s brand and justify price premiums.
Recurring software revenue: Software and autonomous features could become a higher-margin revenue stream over time, decoupled from hardware sales.
Robotaxi and new business models: FSD capabilities are foundational for future services such as robotaxis, which investors and company leadership see as a transformative long-term opportunity.
That said, FSD’s path is far from assured. Adoption in China has been mixed, and local consumer expectations around autonomous features differ from other markets, sometimes leading to criticisms about safety and contextual suitability.
4. Competitive and Structural Risks Remain
Tesla’s narrative is currently shaped by two countervailing forces:
Innovation pipeline and forward-looking products (FSD, AI and robotics) that keep long-term growth stories alive and attract speculative capital.
Core EV sales pressure, as rivals such as BYD, XPeng and others expand their market share with compelling products and aggressive pricing. These companies often bundle advanced driver-assistance features at no extra cost, helping them capture local demand.
The competitive pressure is real, and Tesla’s premiums relative to other EV makers mean that market share gains cannot be taken for granted.
5. Conclusion: Short-Term Confidence, Long-Term Fundamentals
The recent rally on China sales data reflects short-term investor optimism that Tesla can stabilise unit sales in its most important market. The rebound in December was impressive and suggests the company’s operations and sales strategies in China are still effective amid a tougher external environment.
Nonetheless, sustainable future growth will likely require successful rollout and monetisation of software-centric offerings such as FSD, continued innovation in vehicle technology, and strategic responses to strong local competition. FSD may well be a pivotal element in realising higher margins and new revenue streams, but the commercial and regulatory path to broad deployment will be incremental rather than immediate.
In summary, Tesla’s stock and growth prospects still depend on a balance between near-term execution in core vehicle sales (especially in China) and longer-term strategic bets on autonomous software and new business models. Neither exists in isolation, and both will shape the company’s trajectory in 2026 and beyond.
