The global sportswear industry is recalibrating after NBA superstar Stephen Curry ended his 12 year partnership with Under Armour to sign with a Chinese brand. The move, which had been speculated for months, sends ripples through a market already strained by shifting geopolitical winds and a rebalancing of supply chains. For the UK sportswear sector, the implications are twofold: it signals the rise of Chinese brands as genuine competitors on the world stage, and it underscores the volatility of celebrity endorsements in an era of climate conscious consumers and tightening trade regulations.
Curry’s new deal is with Anta Sports Products Limited, a Fujian based company that has been aggressively expanding its footprint beyond China’s borders. Anta already owns the Finnish brand Amer Sports, which includes Wilson and Salomon, and has been positioning itself as a challenger to Nike and Adidas. The financial terms have not been disclosed, but industry analysts estimate the deal could be worth over $1 billion, eclipsing Curry’s previous Under Armour contract. For Under Armour, losing Curry is a blow to its basketball segment, which has been a bright spot in an otherwise challenging decade defined by declining sales and operational restructuring.
From a scientific perspective, Curry’s decision mirrors a broader trend: the decarbonisation of supply chains and the decentralisation of manufacturing hubs. China remains the world’s largest producer of synthetic fibres and finished apparel, but its carbon intensity per unit of output is one of the highest. Anta has announced plans to achieve carbon neutrality by 2050, using recycled polyester and bio based materials in its premium lines. However its supply chain still relies heavily on coal fired power, a contradiction that the UK sector is watching closely. British sportswear brands such as JD Sports and Sports Direct have been under pressure from investors to disclose scope 3 emissions, and any shift in supplier loyalty toward Chinese brands could complicate these efforts.
The UK market for sportswear is worth approximately £13 billion annually, with a growing share going to direct to consumer online sales. The sector is also facing headwinds from inflation and a slowdown in discretionary spending. Curry’s move could intensify competition for shelf space in UK retailers, especially if Anta decides to push its basketball shoes into the European market. While Anta’s products are sold online through platforms like AliExpress, they have limited presence in physical UK stores. A major endorsement like Curry’s could change that, leveraging his popularity among younger demographics who care about performance and, increasingly, brand ethics.
Climate scientists have long noted that consumer goods have a lifecycle impact that extends beyond the point of sale. The microplastics shed from synthetic sportswear during washing contribute to ocean microplastic pollution, a problem that is accelerating with global warming. Curry’s new deal with Anta might accelerate innovation in biodegradable materials, but it also risks locking in more plastic based production if the company fails to scale up sustainable alternatives. The biosphere collapse we are witnessing is not caused by individual transactions; it results from cumulative industrial patterns. For the UK sportswear sector, the key question is whether this deal will push brands to prioritise circular economy models or simply shift market share without reducing environmental impact.
In the short term, investors are reacting cautiously. Under Armour shares dropped 3% following the announcement, while Anta’s stock rose 1.2% on the Hong Kong exchange. The UK sportswear index, which tracks companies such as JD Sports, ASOS, and Nike’s UK operations, remained flat. Analysts point out that the UK market is more aligned with football and running than basketball, so the direct effect may be muted. However the symbolic weight is substantial. A Chinese brand securing arguably basketball’s greatest shooter signals a multipolar future for sportswear, one where Western dominance is no longer guaranteed.
For the environmentally conscious consumer, Curry’s choice may be a litmus test. Under Armour has made strides in reducing water usage and switching to renewable energy in its own operations. Anta’s record is less transparent. But Curry has also been an advocate for social justice and community investment. Whether his new partner meets those standards remains to be seen. As the planet warms, every sponsorship deal carries a carbon shadow. The UK sportswear sector, with its regulatory frameworks and consumer activism, will be a critical arena to watch.
This is not merely a story about shoes. It is about the forces reshaping global production: the rise of new economic powers, the pressure to decarbonise, and the fickle nature of brand loyalty. For now, Steph Curry has made his move. The market is still processing the fallout.
