China EVs Shatter CATL's Battery Monopoly
Chinese electric vehicle manufacturers are aggressively dismantling Contemporary Amperex Technology Co. Ltd.'s (CATL) supply chain monopoly to salvage deteriorating profit margins.
The structural shift in the world’s largest EV market reached a psychological inflection point on September 16, 2026, when CATL’s A-shares dipped below the RMB 300 threshold—a one-year low—before rebounding. The volatility reflects growing investor anxiety as major automakers, including Li Auto, Xiaomi, and Xpeng, actively pivot capital and contracts toward tier-two battery suppliers.
This "De-CATLization" trend signals a fundamental realignment in industry power dynamics. Automakers are no longer content with standard procurement contracts; they are executing strategic equity investments to incubate competitors, dilute CATL’s pricing power, and regain control over their core component costs.
Automakers Battle Squeezed Margins
The urgency to diversify stems from a severe profit imbalance between upstream suppliers and downstream manufacturers. Financial disclosures for the first half of 2026 reveal that CATL generated RMB 43.28 billion (US$6.01 billion) in net profit. In stark contrast, 15 major listed Chinese automakers posted a combined net profit of just RMB 21.05 billion (US$2.92 billion), with 11 of those companies reporting profit declines or outright losses.
While auto industry revenues grew 2.7% to RMB 6.078 trillion (US$844 billion) between January and July 2026, costs outpaced growth at 3.8%. Consequently, the sector's overall profit margin plummeted 20% year-on-year to a dismal 3.6%—well below the 6.5% average for downstream industrial enterprises. Meanwhile, the upstream battery sector, led by CATL, maintained robust gross margins near 20%. With batteries accounting for 40% to 60% of a vehicle's total cost, automakers are effectively bleeding capital to sustain battery manufacturers' profitability.
Tier-Two Suppliers Capture Market Share
To mitigate supply chain risks and enforce cost reductions, OEMs are formalizing alliances with alternative suppliers. On September 4, Li Auto announced an RMB 2.65 billion (US$368 million) capital injection into Sunwoda Power, securing an 11.17% stake. Li Auto has completely phased out CATL from its L8 model lineup in favor of Sunwoda and is transitioning its MEGA models to proprietary 5C batteries.
Simultaneously, Xiaomi formalized a strategic partnership with CALB to co-develop "Dragon Armor" batteries, shifting reliance away from CATL units previously used in its SU7 and YU7 models. Xpeng has aligned with EVE Energy, while Seres integrated Gotion High-Tech into its supply chain.
These maneuvers have eroded CATL’s absolute dominance. While the company saw a slight recovery to a 45.37% domestic market share in the first seven months of 2026, this follows a drop to 43.42% in 2025—its lowest point in years.
Tech Parity Drives Structural Shift
The feasibility of this diversification strategy relies on the narrowing technological gap among Chinese battery manufacturers. In the lithium iron phosphate (LFP) segment, tier-two companies have achieved near-parity in cell chemistry. EVE Energy’s success in securing contracts for BMW’s Neue Klasse platform via large cylindrical batteries demonstrates that alternative suppliers can bypass traditional form-factor competition and meet global premium standards.
Despite the shifting landscape, CATL retains a formidable defensive moat built on intellectual property and scale. The company secured 3,210 new patents in the first half of 2026 alone. Analysts project that while CATL’s market share will experience marginal dilution, its leadership position remains secure in the near term.
Over the next three to five years, the Chinese EV supply chain will likely transition from a single-supplier hegemony to a fragmented ecosystem characterized by deep cross-shareholding and joint R&D ventures between automakers and tier-two battery firms.
