Sales growth at BYD slowed sharply in 2025, underlining mounting pressure on China’s largest electric vehicle maker as intensifying competition at home and signs of a fading technological edge begin to weigh on its dominance.

The sharp deceleration in sales is more than a China-only story. It marks a turning point with implications for the global electric vehicle market, where competition is intensifying, margins are thinning, and the long-simmering rivalry between BYD and Tesla is taking on a more complex, global character.

The Chinese automaker said full-year sales rose 7.73% to 4.6 million vehicles, its weakest growth in five years. December sales fell 18.3% year-on-year, extending a four-month slide and marking the steepest monthly drop in nearly two years. The slowdown followed BYD’s decision to cut its 2025 sales target by 16%, an acknowledgment that domestic demand had weakened sharply from mid-year amid fierce competition from Geely, Leapmotor, and other fast-moving rivals.

At home, the data point to a market that has entered a more mature and unforgiving phase. Price cuts, once a lever to rapidly expand market share, are now yielding diminishing returns. BYD’s decision in May to slash prices across more than 20 models triggered a selloff in Chinese auto stocks and prompted Great Wall Motor’s chairman to warn publicly that China’s auto industry was in an “unhealthy” state. That comment captured a broader concern: China’s EV market, the largest in the world, is becoming oversupplied, with too many players chasing slowing demand.

Chinese media outlet Southern Metropolis Daily reported that BYD chairman Wang Chuanfu told investors in December that the company’s domestic struggles reflected a weakening of its technological leadership. Wang said BYD would roll out major innovations in 2026, a signal that management believes the next phase of competition will hinge less on price and more on differentiated technology.

Over the past year, BYD has already pushed hard on features. It introduced advanced driver-assistance systems on vehicles priced below $10,000 and launched models boasting ultra-fast charging. However, rivals quickly matched or undercut those moves, eroding BYD’s advantage and forcing it into a margin-sapping price war. The pressure has been significant enough that BYD slowed production and delayed capacity expansion in mid-2025, according to Reuters, a notable shift for a company long defined by relentless scaling.

These dynamics matter globally because China has been the engine of EV growth worldwide. A cooling Chinese market increases the incentive for domestic champions like BYD to look outward, exporting both vehicles and competitive pressure to Europe, Southeast Asia, Latin America, and beyond.

That shift is already underway. BYD’s overseas sales surged 150.7% in 2025 to just over 1 million units, becoming the company’s main growth driver. Europe, in particular, has emerged as a key battleground. BYD’s competitively priced models have gained traction as consumers grapple with high inflation and rising interest rates, conditions that favor lower-cost EVs over premium offerings.

This is where the implications for Tesla become most pronounced. In 2025, BYD sold 2.26 million electric vehicles, positioning it to overtake Tesla in annual EV sales for the first time. Tesla was expected to deliver about 1.64 million vehicles, an 8.3% decline from the previous year. The crossover is symbolic, highlighting a shift in the center of gravity of the EV market toward manufacturers that can deliver scale at lower price points.

Tesla’s strategy, however, is diverging sharply from BYD’s. Elon Musk has deprioritized plans for a mass-market $25,000 EV, instead focusing Tesla’s future on artificial intelligence, full self-driving software, and robotaxis. Musk has said these technologies, rather than vehicle volume alone, will define the next era of automotive competition.

BYD, by contrast, remains firmly committed to volume, vertical integration, and aggressive pricing, backed by control over key parts of its supply chain, including batteries. That approach gives BYD resilience in a global market where affordability is becoming more important, particularly as governments scale back EV subsidies and consumers become more price-sensitive.

The rivalry is therefore no longer just about who sells more cars. It reflects two competing visions of the EV future. Tesla is betting that software, autonomy, and AI-driven services will justify higher prices and unlock new revenue streams. BYD is betting that scale, cost control, and steady incremental innovation will win over mass-market buyers across multiple regions.

But BYD’s domestic slowdown now introduces a note of caution into that strategy. Margin pressure at home could limit how aggressively it can price vehicles abroad without hurting profitability. At the same time, intensifying scrutiny in Europe and the United States over Chinese EV imports, including tariffs and trade investigations, could complicate its overseas expansion.

Still, BYD’s ability to offset weakness in China with explosive growth abroad underscores how competitive the global EV market has become. The rise of BYD as a credible global Tesla rival reinforces the reality that competition is no longer coming only from Silicon Valley or Detroit, but from Chinese manufacturers willing to fight on price, scale, and speed.

The EV industry is entering a more demanding phase as 2026 approaches. Growth is slowing in key markets, technology advantages are narrowing, and the battle is shifting from early adoption to mass-market sustainability. BYD’s stalling momentum at home and accelerating push abroad capture that transition — and set the stage for a more intense, globally consequential rivalry with Tesla.

ByteDance is preparing to spend about 100 billion yuan ($14 billion) on artificial intelligence chips from Nvidia in 2026, a sharp increase from roughly 85 billion yuan this year, according to people familiar with the matter who spoke to SCMP.

The proposed spending, which underscores both the scale of its AI ambitions and the strategic importance of access to U.S. chip technology, hinges on whether Nvidia is ultimately allowed to sell its H200 graphics processing units to Chinese customers, a decision that remains subject to regulatory approval in Beijing despite Washington recently easing restrictions on the chip.

The budget, sources cautioned, could still change depending on policy outcomes and market conditions.

The planned outlay forms part of ByteDance’s broader push to dramatically expand capital expenditure on artificial intelligence next year. The Beijing-based company, which is privately valued at about $500 billion, is preparing to lift total AI investment to as much as 160 billion yuan in 2026, according to a Financial Times report earlier this month.

At the heart of the strategy is ByteDance’s surging demand for computing power across its sprawling ecosystem, which includes TikTok and Douyin, its rapidly growing cloud business Volcano Engine, and its expanding suite of large language models.

Volcano Engine, ByteDance’s enterprise cloud arm, is set to become the exclusive AI cloud partner for China Central Television’s Spring Festival Gala, the most-watched television broadcast in the country. The partnership highlights how deeply embedded ByteDance’s infrastructure has become in high-profile national platforms, further intensifying its need for reliable, large-scale AI compute.

The company’s chatbot, Doubao, illustrates the pace of that growth. Doubao is now processing more than 50 trillion tokens per day this month, up from just 4 trillion tokens in December 2024. Tan Dai, president of Volcano Engine, recently said the platform has served more than 100 corporate clients, collectively processing over 1 trillion tokens to date.

Alongside its reliance on Nvidia, ByteDance is working to reduce long-term exposure to supply constraints and geopolitical risk by building internal semiconductor capabilities. Its in-house chip design unit, which employs around 1,000 staff, has made progress on a processor that matches the performance of Nvidia’s H20 chip — a China-tailored product — but at a lower cost, according to one of the sources.

The H20 was designed by Nvidia to comply with earlier U.S. export controls before being blocked, and its absence has accelerated efforts by Chinese firms to develop domestic alternatives. ByteDance is not alone in this push. Other Chinese technology groups are pursuing similar strategies to gain greater control over chip supply, pricing, and long-term planning.

Beyond processors, ByteDance has also been investing in memory technologies, including high-bandwidth memory, through a combination of internal research and equity stakes in specialized start-ups. These components are critical for training and running large AI models efficiently, and shortages can be as constraining as limited access to GPUs.

Internally, ByteDance’s chip arm works closely with Seed, the company’s frontier AI research team, highlighting how semiconductor design is becoming increasingly central to core AI development rather than a peripheral function.

Reflecting growing geopolitical sensitivity, ByteDance transferred its chip unit to a Singapore-incorporated subsidiary, Picoheart, in September. The move came amid intensifying China–U.S. tensions over technology. Some employees based in mainland China have been asked about relocating to Singapore, particularly those working on projects considered more sensitive, according to staff familiar with the discussions.

On the supply side, Nvidia is racing to capitalize on pent-up Chinese demand. The company hopes to ship its newly approved H200 chips to Chinese customers before the Lunar New Year holiday in mid-February, Reuters has reported. Interest from Chinese technology groups has been strong, though Beijing has yet to approve any purchases, leaving timelines uncertain.

The H200 is Nvidia’s second-most powerful AI chip and a significant step up from products currently available to many Chinese firms. That performance gap explains why companies like ByteDance are willing to allocate tens of billions of yuan to secure access, even as domestic chipmakers gain ground.

Beijing, for its part, is attempting to strike a careful balance. While authorities want to accelerate AI development to support economic growth and technological leadership, they are also keen to promote the adoption of domestic chips from companies such as Cambricon Technologies, Huawei’s Ascend unit, Moore Threads Technology, and MetaX Integrated Circuits.

Whether ByteDance ultimately gets the green light to deploy Nvidia’s H200 at scale will be a key test of how that balance is managed — and a signal of how far China is willing to lean on foreign technology as it races to build its AI future.
