Marketability has always meant many different things to many different people. In the sports industry, commercial viability is very much in the eye of the beholder, shaped by shifting corporate goals, regional nuances, and an evolving digital landscape.
Since 2010, when SportsPro first compiled its annual list of the world’s 50 Most Marketable Athletes, researchers and editors have spent untold hours attempting to decode what defines athletic marketability and, specifically, what makes one competitor more commercially attractive than another. It remains an inexact science, dependent upon an extensive and ever-evolving array of variables that defy a one-size-fits-all approach.
No single ranking can possibly please every sports fan, as evidenced by the passionate social commentary that invariably accompanies the annual release. Nor can any static list meet the distinct needs of every organization or corporate sponsor. The global head of sponsorship at an established multinational corporation will naturally hold a very different view of an athlete’s commercial power compared to the chief executive of a fledgling challenger brand that is prioritizing rapid growth within a specific market or among a very particular demographic.
Some brand marketers actively seek broad geographic reach and mainstream visibility, aiming for household-name recognition across multiple continents. Others look for authentic ambassadors with local or regional relevance, preferring smaller but deeply engaged communities of followers over passive mass audiences. Furthermore, some brands prioritize consistent activity and high interaction rates on specific digital platforms over raw performances on the field of play, while others simply want to sign the most famous athlete their marketing budget can buy.
Put simply, an individual athlete’s marketability can be defined as the extent to which they influence consumer purchasing behavior and brand affinity. However, that baseline definition says little about what actually drives that influence. In reality, an athlete’s ability to convert casual fans into active consumers depends on a multitude of intersecting factors. These range from personal attributes—such as raw personality, athletic talent, public presentation, and personal reputation—to external conditions like the economic size of their home market or the global reach and cultural relevance of the sport in which they compete.
For that very reason, the variables that render an athlete marketable have transformed dramatically over the last decade and a half, and the analytical model powering SportsPro’s flagship list has evolved right alongside them. Marketability used to be predominantly a question of raw fame and media exposure. Today, it is fundamentally about the relationship between an athlete and their audience: how strong that connection is, which direction it is moving, and how much potential is still left to be unlocked.
Indeed, when it comes to assessing athlete marketability, timing is everything and context matters immensely.
Brand marketers must grapple with a complex series of questions before committing capital. How many official partners does an athlete already have in their portfolio, and in which specific commercial categories? How willing and able are they to accept new sponsors given their existing competitive and commercial commitments? Where is their audience geographically distributed, and what does that demographic makeup look like? What major tournaments and marquee events are they competing in during the calendar year? How much career runway do they have ahead of them before retirement or decline? How visible and influential are the organizations and teams they represent? What is the current state of public sentiment toward them? And, crucially, to what extent can they speak authentically about the complex topics and social issues that drive modern cultural conversations?
Many of these questions are far from easy to answer, yet they represent vital considerations for any corporate marketer holding a budget destined for athlete sponsorship. Equally challenging is the foundational task of compiling a ranking that attempts to compare vastly different types of athletes, across a wide spectrum of sports and geographies, in a definitive and standardized way.
Though SportsPro lays claim to the most comprehensive assessment of athlete marketability undertaken anywhere in the sports industry, the list of the world’s 50 Most Marketable Athletes remains precisely that—SportsPro’s list. It is built using NorthStar’s sophisticated, data-driven marketability assessment model, but it ultimately represents just one possible ranking based on an editorial understanding and definition of marketability that has been carefully developed and refined over the course of 16 years.
Equity Meets Momentum
The core editorial view guiding these rankings is that the most marketable athletes in any given year are not simply those who are winning championship titles or breaking through competitively. Rather, they are the individuals emerging as highly desirable spokespeople in an increasingly cluttered sports marketing landscape because they possess a unique story to tell and are actively cultivating deeply engaged digital followings, particularly through the clever and authentic use of social media.
More specifically, those experiencing the most accelerated growth in reach, engagement, and cultural relevance are identified as the most commercially appealing partners for brands. Whether they are established veterans or rising stars, their steep upward trajectory signals untapped marketing potential, indicating future commercial opportunities that likely exceed their present scale.
Working closely with analytics partner NorthStar, the assessment model has been restructured around three distinct pillars: brand equity, momentum, and commercial trajectory. In previous iterations, the model’s drivers were composites weighted heavily toward established equity, recognizing momentum only through a set of scoring boosts without any dedicated measure of future trajectory.
Under the updated framework, each of the three elements has its own dedicated pillar and specific drivers. Brand equity remains the single largest pillar, accounting for 45 percent of the total NorthStar Marketability Score. However, the two forward-looking pillars together carry 55 of the 100 available points. This structural shift ensures that built-up brand equity successfully gets an athlete into commercial contention, but momentum and future trajectory ultimately differentiate the top performers.
Consequently, the ranking is explicitly designed to highlight the current and future commercial trajectory of athletes competing globally, rather than merely reflecting their individual marketability over the entire fullness of time. True marketability encompasses this delicate interplay of past foundations, present realities, and future possibilities.
An athlete’s accumulated brand equity is defined as the trust, reach, and commercial standing that establish where they stand today. Momentum signals the direction and pace of change in that equity—measuring whether public attention and digital engagement are actively building, and whether commercial brands are naturally moving toward the athlete. Meanwhile, commercial trajectory acts as a forward-looking measure, assessing the room left for growth in terms of career years, untapped geographic markets, and unexploited sponsorship categories.
Assessing athletes through this multifaceted lens returns the process to the true root of the 50 Most Marketable Athletes ranking, affectionately known within the industry as 50MM.
In its earliest years, the initiative was entirely focused on identifying up-and-coming talent poised to break through on a global scale. Initially, athletes were ranked according to relatively rudimentary criteria such as perceived value for money, a willingness to be actively marketed, youth, and projected marketing potential over a three-year horizon, all with the goal of showing brands where they could generate the most return on investment.
That core logic still applies in the modern, data-driven era, but it operates with added nuance. Most corporate sponsors sign athletes for the duration of a multi-year contract rather than for a single fleeting moment in time. Two different athletes can possess identical commercial profiles today and score similarly within the baseline model, yet be heading in diametrically opposite directions.
If an athlete’s commercial trajectory is defined by their capacity for future growth rather than their current stature, then career runway—or the lack thereof—must be factored directly into the calculation. A lengthy career runway amplifies other growth factors, but that runway naturally narrows with age. Similarly, monetization headroom—the degree to which an athlete’s brand strength exceeds what is already being actively monetized—serves as a vital metric that shifts dynamically as a career progresses.
Consider the case of Harry Kane. Few observers would deny that England’s record goalscorer and high-profile star is immensely marketable. Data tracked by NorthStar indicates that his current commercial returns, led heavily by estimated media value, remain strong relative to his overall brand profile. However, at age 33, he possesses less remaining career runway than many of the younger athletes surrounding him on the list. Consequently, the model reads his commercial value as already well-realized, leaving limited untapped headroom and resulting in a lower commercial trajectory score.
Crucially, a comparatively low commercial trajectory score does not indicate weak marketability. Instead, it signifies that an athlete’s marketability is mature, stable, and already robustly commercialized. Kane secured a notable placement on the list entirely on the strength of his towering brand equity and momentum scores, proving that established value still carries immense weight.
One Model, Many Configurations
One of the most fascinating aspects of compiling the rankings is the way subtle adaptations in the assessment model can produce radically different outcomes.
Each configuration answers a distinct strategic question. Tipping the scales heavily toward brand equity naturally causes established household names to rise to the top. Shifting the balance toward momentum brings rising stars and viral sensations to the fore, with only a few notable exceptions. SportsPro’s published list reflects its own editorial view of marketability, expressed through specific weighting choices, but NorthStar’s underlying model can be configured with equal purpose for entirely different corporate goals, utilizing different weightings, alternative inclusion criteria, or a customized selection of drivers tailored to a specific brand brief.
Interestingly, across the 247 athletes fully assessed by the model, the statistical correlation between brand equity and momentum is close to zero. Furthermore, no single athlete appearing in the top ten on one measure overlaps with the top ten of the other. This stark divergence highlights unavoidable tensions within the industry, such as how to properly weigh an athlete’s marketability today against their speculative future potential, or how to balance an established profile against emerging opportunities.
“What we’re seeing is that, from the overall marketability standpoint, you have athletes that have built brand equity through long and successful careers. But that doesn’t necessarily mean that they have current-day momentum,” explains Chris Collins, founder, chief executive, and president of NorthStar Solutions Group. “Likewise, you may find athletes that have a lot of current-day momentum, but they may be earlier in their career and maybe haven’t converted that momentum into stable brand equity.”
Collins notes that while overlap between the two metrics is rare, exceptions do occur. He points to top-ranked Aryna Sabalenka as a prime example of an athlete who successfully performs across all three pillars. Sabalenka earned more than 70 percent of the available points across equity, momentum, and commercial trajectory, standing alone as the only athlete among the 247 assessed to achieve that feat.
Other challenges remain inherent within the process of compiling the rankings. Every year, the availability and quality of data serve as critical considerations. Publicly available data is frequently incomplete, making it impossible to assess every athlete on a completely level playing field without rigorous adjustment, and any data utilized must be thoroughly validated and verified for absolute accuracy.
NorthStar utilizes data feeds from various leading industry providers, but how that raw data is channeled into the different drivers of the model remains crucial. By expanding the slate of drivers to 27 per athlete, the analytical depth and granularity have increased significantly, ensuring that overlapping data points are not inadvertently measuring the exact same underlying phenomenon twice.
“We’ve obviously refined the model, gotten better, gotten more efficient,” Collins adds. “There’s more data that’s out there. The tools that are available to measure it and process it have gotten better, and we’re continually integrating them into our overall platform and what we do. So, we continue to evolve with it.”
That continuous evolution opens up new possibilities for future athlete rankings while underlining the overarching power of the underlying analytical platform. The system is comprehensive in its broad scope yet sufficiently malleable to evaluate commercial opportunities against any organization’s distinct priorities and strategic objectives.
Once those organizational priorities and objectives are clearly defined, the model can be configured to reflect them directly, altering the weighting of marketability drivers to produce a desired outcome. SportsPro’s published list represents just one specific configuration of the platform; the exact same data engine can be deployed to answer a corporate sponsor’s specific brief, audit an agency’s existing athlete roster, or comprehensively assess the commercial pull of a team, league, or entire sports program.
“There’s an engine underneath all of this,” Collins explains. “The cool part about what we built is anybody can come to us, right? It could be a different list. Somebody may want to know the most marketable women athletes in a specific country or a specific sport. And we would collect the requirements and then configure and tune the model to drive that.”
The system can work directly with individual athletes or talent representation agencies to help them understand where they currently stand, where they are excelling, and where commercial gaps exist that might benefit from targeted strategic investment. It can also analyze the intricate interplay between corporate sponsors and the specific athletes they choose to back, evaluating portfolio gaps and helping brands decide whether an athlete represents a stable value play, a high-growth opportunity, or a piece of a broader, diversified marketing strategy.
With a multitude of use cases spanning diverse sports industry stakeholders, the methodology demonstrates how modern data science continues to reshape the landscape of athlete sponsorship and commercial evaluation.
