How Mega-Events Reshape Economies Before They Happen

Mega-events beyond the headline numbers

‍

Mega-events generate substantial economic activity. They mobilize public spending, increase tourism flows and concentrate international attention in a short period of time. This short-term boost is well documented across major international sporting events. What research also shows, however, is that this surge in activity does not automatically translate into lasting economic gains once the event has passed. Studies analyzing co-hosted World Cups and large-scale sporting events point to a consistent pattern: long-term outcomes depend primarily on pre-existing infrastructure, institutional quality and the efficiency of public investment, rather than on the event itself (Kehel, 2025).

‍

Rather than creating new growth independently, mega-events tend to accelerate economic trajectories that are already in motion. When governance frameworks are solid and infrastructure is largely in place, the preparation phase can reinforce existing strengths. When these conditions are weaker, the same investment effort often leads to cost overruns and limited structural impact. This imbalance is described in the literature as a form of “winner’s curse”, where the scale of the event amplifies underlying weaknesses instead of correcting them (Ait Soussane & Ibourk, 2025).

‍

Where economic outcomes are shaped

‍

The economic relevance of a mega-event takes shape well before the event itself. The years leading up to it concentrate the most consequential decisions, including public investment approvals, infrastructure prioritization and regulatory coordination. Research on large international sporting events shows that this preparatory phase accounts for the bulk of the economic effects associated with hosting, rather than the event period itself (Kehel, 2025).

‍

By the time the event takes place, much of its economic outcome has already been determined. Infrastructure has been delivered, budgets committed and resources allocated. Analyses comparing World Cup host countries with different levels of institutional quality and public investment efficiency show that the event tends to function as a deadline for executing decisions already in progress, rather than as a trigger for new economic dynamics (Ait Soussane & Ibourk, 2025).

‍

This sequencing helps explain why mega-events should be understood as forward-looking economic signals. Their significance lies in how early planning shapes capital deployment and institutional behavior over time, not in the short-lived activity generated during the event itself.

Portugal’s track record with mega-events

‍

Portugal has already experienced several large-scale international events, offering a useful reference for how these cycles tend to unfold in practice. Rather than reshaping the economy overnight, these events have typically served to unlock execution, accelerating projects and decisions that were already planned or politically viable.

‍

Expo 98

‍

Expo 98 remains the clearest example of a mega-event with lasting structural impact. Its economic relevance did not come from the exhibition itself, but from the urban redevelopment carried out in the years leading up to it. Investment focused on transport infrastructure, utilities and land regeneration, transforming Lisbon’s eastern waterfront into what is now Parque das Nações, a change that extended well beyond the event period (Aelbrecht, 2012).

‍

UEFA Euro 2004

‍

Euro 2004 played a key role in accelerating infrastructure investment and strengthening Portugal’s capacity to host complex international events. It improved transport connectivity, enhanced institutional coordination and reinforced the country’s visibility as a reliable host. At the same time, post-event analyses show that economic outcomes were uneven across host cities, particularly where stadium investment was not aligned with long-term demand, highlighting the importance of matching event-related spending with post-event use (Power & Sidaway, 2005).

‍

Web Summit

‍

The Web Summit, hosted in Lisbon since 2016, illustrates a different economic dynamic. Unlike large sporting events, it required limited upfront public investment and no major new infrastructure. Its impact has instead been cumulative, driven by recurring international business travel, global visibility and continuous exposure to technology and innovation networks. Over time, this continuity has contributed to Portugal’s repositioning within the European tech ecosystem, generating more persistent effects than those typically associated with short-duration, high-CAPEX events (Moreira, 2018).

Taken together, these precedents point to a consistent pattern. Portugal tends to capture more durable economic benefits when mega-events are used to advance existing strategies rather than to justify large-scale, standalone investments. This historical context provides a useful lens for assessing future mega-events.

The 2030 World Cup as a shared economic framework

‍

The FIFA World Cup 2030 introduces a materially different hosting model for Portugal. Rather than a single-country structure, the tournament is being co-hosted with Spain and Morocco, distributing infrastructure requirements, public spending and administrative responsibilities across three economies. This shared framework alters the economic dynamics typically associated with World Cup hosting.

‍

Academic work focused on the 2030 tournament examines how this co-hosting model affects investment intensity and risk distribution. Analyses of the Portugal–Spain–Morocco framework show that Portugal enters the cycle with relatively limited direct capital expenditure requirements, relying largely on existing infrastructure while benefiting from coordinated planning and transnational tourism flows (Kehel, 2025). This reduces exposure to the high upfront investment risks that have characterized previous single-host World Cups.

‍

Institutional context further shapes potential outcomes. Comparative studies analyzing World Cup host countries through differences in institutional quality and foreign direct investment performance show that economies with stronger governance frameworks are better able to convert mega-events into sustained indirect benefits, particularly when investment pressure is shared rather than concentrated (Ait Soussane & Ibourk, 2025). In this context, Portugal’s role is defined less by expansion and more by optimisation.

‍

Viewed through this lens, the 2030 World Cup functions primarily as a coordinating signal rather than a growth driver. It brings forward execution and alignment across sectors that were already in motion, while limiting the risk of over investment. This makes it a useful case for understanding how mega-events can influence economic trajectories without redefining them.

What this means for Portugal’s investment landscape

‍

This analysis helps clarify how mega-events fit within Portugal’s current economic and investment context. Rather than acting as standalone growth drivers, they interact with an economy that has already prioritised institutional stability, infrastructure readiness and capital discipline. In this setting, hosting reinforces existing strengths instead of reshaping economic fundamentals.

‍

For international investors, this distinction is central. Portugal’s appeal increasingly rests on predictability, regulatory clarity and the ability to absorb capital without abrupt policy shifts or excessive public spending. Mega-events aligned with these conditions tend to support visibility, coordination and confidence, rather than introduce volatility.

‍

This environment is particularly relevant for long-term capital seeking structured exposure. Portugal’s economic model, combined with regulated investment routes and residency-by-investment mechanisms, reflects an approach focused on transparency, gradual deployment and resilience across political and economic cycles.

‍

Viewed through this lens, mega-events do not create opportunity on their own. They reveal how an economy manages scale, scrutiny and international attention. In Portugal’s case, that signal is consistent with an investment landscape oriented toward stability, optimization and long-term positioning rather than event-driven growth.

Portugal’s Golden Visa, hospitality and long-term investment

‍

The Portugal Golden Visa is directly linked to Portugal’s economic strategy of attracting long-term capital into productive sectors, with hospitality playing a central role. Rather than driving short-term speculation, the program channels investment into regulated funds that support hotel operations, asset repositioning and tourism infrastructure. In the context of sustained tourism demand and major international visibility toward 2030, this model reinforces economic activity that is already structurally embedded in the Portuguese economy.

‍

For investors, this translates into a residency-linked investment aligned with real economic fundamentals. Through regulated hospitality vehicles such as those managed by VIDA Capital, capital is deployed into operating hotel assets designed to capture long-term tourism and mobility trends. In this sense, the Golden Visa is not a standalone benefit, but part of a broader investment framework combining residency, economic participation and exposure to Portugal’s hospitality sector.
