The FIFA World Cup has been capturing the attention of football fans around the world for almost two weeks. In Poland, the excitement is somewhat lower than usual, as the national team is not among the tournament’s participants this time. Yet the World Cup remains not only a sporting celebration, but also one of the largest business events in the world.
While national teams compete on the pitch, an equally intense battle is taking place in the background between the brands that have dressed football’s biggest powers for decades and built their global position on the popularity of the sport. One might assume that such a major tournament should benefit Adidas and Nike shareholders. History, however, tells a very different story.
Data from the last six World Cups show that share-price declines have been more common than gains during the tournament itself. What is more, for the stock market, the weeks before the opening match and after the final often matter more than the matches themselves. The pitch lives to the rhythm of 90 minutes — lately often a little longer — but financial markets look much further ahead, pricing not the result of the next game, but what may happen in the months or even years ahead.
Legendary Polish coach Kazimierz Górski, the architect of Poland’s greatest football successes, used to say that “the ball is round and there are two goals.” Around every World Cup, however, another match is played — far less visible, but worth billions of dollars. While national teams compete for the trophy, global brands battle for fans’ attention and future profits.
Adidas has supplied the official World Cup ball for more than 50 years, while Nike outfits many of the world’s most recognisable national teams. Intuition suggests that the tournament should help both companies. Yet history shows that sporting excitement does not always translate into stronger sales or higher share prices.
Data from the six World Cups held in the 21st century indicate that the tournament is not necessarily a favourable period for sportswear manufacturers. Adidas shares ended the tournament period lower in five out of six cases, generating an average return of -3.95%. Nike performed slightly better, with an average return of +0.56%, but even here it is difficult to identify a clear and repeatable pattern.
Interestingly, in none of the World Cups analysed did both companies record decisive gains at the same time during the four-week tournament period. An even more revealing picture emerges when the perspective is extended to include one month before the tournament and one month after its conclusion.
Historically, both Adidas and Nike have more often delivered stronger results before the opening whistle or after the final than during the tournament itself. This resembles the well-known stock-market principle of “buy the rumour, sell the news”, under which investors buy on expectations ahead of an event and take profits once the event is already under way.
It should be remembered, however, that the analysis is based on only six observations. Even such interesting data should therefore be treated more as an indication than as a hard-and-fast market rule.
Success on the pitch does not automatically mean success on the stock market
The performance of Adidas and Nike after previous World Cups illustrates this clearly. Adidas dressed the World Cup winners in 2010, when Spain won the tournament, in 2014, when Germany lifted the trophy, and in 2022, when Argentina became champions.
However, the company’s monthly share-price returns after those tournaments were +1.99%, -6.12% and +21.63% respectively. It is difficult to identify any consistent pattern in these figures.
A similar situation can be seen in the case of Nike, which sponsored the winning national teams in 2002, when Brazil triumphed, and in 2018, when France won the title. In the first month after the tournaments ended, Nike shares generated returns of -7.45% and +2.86% respectively.
In one case investors gained, in the other they lost. In practice, even winning the World Cup with a sponsored national team does not guarantee a rising share price. Financial results, sales prospects and the condition of the wider economy remain far more important to the market than sporting triumph.
Adidas and Nike move in very different directions
The most interesting difference between Adidas and Nike has emerged in the period between consecutive tournaments. Since the World Cup final in Qatar on 18 December 2022, Adidas shares have risen by almost 44%, while Nike has lost 59% of its value.
Adidas has also clearly outperformed Nike this year. Since the start of the year, its shares have gained nearly 4%, while Nike stock has fallen by almost 32%. This shows that success is not determined by the number of sponsored teams or World Cup emotions, but by the effectiveness of a company’s strategy and the overall health of its business.
Under the leadership of Bjorn Gulden, who returned as chief executive in 2023, Adidas has successfully rebuilt its position. The company has placed greater emphasis on the combination of sport and lifestyle, expanded its apparel business and increased its presence in China and Latin America.
The effects are visible in its results. In the first quarter of 2026, Adidas revenue increased by 14%, operating margin reached 10.7%, and operating profit came close to EUR 705 million.
Nike is facing a very different set of challenges. Elliott Hill, who returned as CEO in autumn 2024, took over a company struggling with excessive inventories, weaker wholesale sales and market saturation in popular footwear models.
The turnaround process is continuing, but it is weighing on results. In the third quarter of fiscal 2026, revenue fell by 3%, while gross margin declined by 130 basis points to 40.2%. In addition, guidance for the following quarter assumes a 2–4% revenue decline, alongside an approximately 20% fall in sales in China.
The World Cup is a marketing stage, not a substitute for business performance
Adidas therefore enters the World Cup with a strong income statement, a credible strategic plan and the additional advantage of supplying the official ball used in every match of the tournament.
Nike enters the same period under greater pressure, although early signs of stabilisation in North America and a planned Investor Day in the autumn give investors hope for a clearer roadmap for the group’s recovery.
This shows that the World Cup can be a major marketing stage for brands, but it cannot replace rising revenue, healthy margins or confidence in management strategy.
The most important lesson from World Cup history is simple: a major tournament can increase brand recognition, but the value of a company’s shares is determined not by the result of the final, but by the quality of the business long after the final whistle.
