The Life-Changing Offer That Launched Lionel Messi’s Legendary Career

When Lionel Messi was a teenager, a seemingly simple yet extraordinary deal sketched informally on a napkin altered the course of football history. This humble contract included not just the basics of joining FC Barcelona’s youth team but also an unconventional clause that would prove pivotal: the club’s commitment to pay for Messi’s growth hormone treatment. This commitment laid the foundation for one of the most remarkable sports careers the world has ever seen.

The Growth Hormone Treatment: A Gamble That Paid Off

Messi’s local Argentine club, Newell’s Old Boys, had hesitated over the expense and risk of funding the treatment. To them, investing heavily in a young and unproven player was just too great a gamble. Barcelona, on the other hand, saw potential and invested in Messi’s future.

The growth hormone therapy was effective, and Messi’s physical development improved markedly. From that point, his career trajectory skyrocketed, not only bringing personal glory but also catapulting Barcelona — and later the Spanish national team — to international dominance. This early gamble by FC Barcelona arguably became the best money ever spent on a young athlete.

Messi’s Rise to Billionaire Status

Off the field, Lionel Messi has also achieved monumental success, particularly financially. At 38, Messi has earned over $700 million in salary and bonuses since 2007, according to Bloomberg. When factoring in taxes, investments, and sponsorship income, his net worth has soared past the $1 billion mark — according to the Bloomberg Billionaires Index.

This milestone places him alongside his longtime rival Cristiano Ronaldo, who became the sport’s first billionaire after moving to Saudi Pro League club Al-Nassr FC in 2023. Together, these two icons represent the elite circle of the world’s wealthiest athletes.

A Career Driven by Passion, Not Money

In an interview with Mundo Deportivo, Messi spoke candidly about his motivations. “Money was never a problem for me, nor an obstacle in anything,” he said. “If it had been about money, I would have gone to Saudi Arabia or somewhere else.” This speaks volumes about Messi’s dedication to the sport itself, above financial incentives.

Innovative Deals with Inter Miami

Messi’s move to Inter Miami in the United States added new dimensions to his career and earnings. His contract featured groundbreaking perks, including an unusual equity option allowing him to purchase a stake in the club. David Beckham, a retired English football legend and one of the club’s shareholders, had already set a precedent.

While it’s unclear whether Messi has exercised his option to acquire equity, Inter Miami’s value has surged. As of February, the club was valued at approximately $1.45 billion — a 20% increase — making it the most valuable soccer team in the U.S., 16th globally, and more valuable than prestigious clubs like Newcastle United.

New Revenue Streams: Streaming and Beyond

Messi’s transfer to the U.S. wasn’t just about traditional salary and bonuses. During contract negotiations, there were discussions between the MLS and Apple about a potential revenue-sharing agreement. This deal would provide Messi with a share of sales from new subscriptions to Apple TV+’s MLS Season Pass, marking a new frontier in athlete compensation.

Jorge Mas, Inter Miami’s owner, revealed that subscriptions to the streaming service doubled shortly after Messi joined, underscoring the immense impact of his presence. Mas also estimated Messi’s total annual earnings from the club — including equity rights and player pay — between $70 million and $80 million.

Off-Field Management and Business Ventures

Messi’s off-field affairs have been closely managed by his father, Jorge, who acts as agent, business manager, and adviser. This family partnership has been crucial in navigating his vast business empire.

One of the key figures in Messi’s investment portfolio is Alfonso Nebot Armisen, a relatively low-profile Spanish banker managing a private investment firm since 2009. However, Messi’s business dealings have not been without controversy. Both Messi and Ronaldo faced scrutiny by Spanish tax authorities. A decade ago, Messi and his father were convicted of defrauding Spain of roughly 4 million euros related to image rights income. Though sentenced to prison, Messi ultimately avoided jail time but paid fines.

Diversifying Investments Beyond Football

Since then, Messi has continued to diversify his portfolio beyond his football earnings. In December 2024, he listed a Real Estate Investment Trust (REIT) on a minor Spanish exchange valued at $232 million. The company, Edificio Rostower Socimi, manages various hotels and commercial real estate properties.

This foray into real estate marks Messi’s strategic expansion into wealth management — a move that will safeguard his financial future long after his playing days conclude.


Lionel Messi’s story is not just one of dazzling skill and trophies but also of calculated risk, innovative agreements, and shrewd financial management. From a napkin contract that underwrote his growth hormone treatment to becoming a sporting billionaire and savvy businessman, Messi’s journey is a testament to talent meeting opportunity and vision.
