Les 10 plus grosses entrées en Bourse de l’histoire – A 2026 analysis of the 10 largest initial public offerings (IPOs) reveals how they reshaped global capital markets, with Saudi Aramco’s 2019 $29.4B debut leading the pack. These events reflect economic cycles, regulatory shifts, and investor sentiment, offering critical insights for portfolio managers and policymakers.
The 2026 market landscape is defined by a reevaluation of historic IPOs, driven by renewed interest in energy, tech, and emerging markets. While the original TVA Nouvelles article listed the top 10, it omitted key financial metrics and macroeconomic implications. This analysis fills those gaps, linking these events to current market dynamics.
The Bottom Line
- Saudi Aramco’s 2019 IPO remains the largest at $29.4B, bolstered by $11.7B in annual EBITDA.
- Alibaba’s 2014 listing ($25B) catalyzed China’s tech boom, with a 2025 revenue of $126.8B.
- Current interest rates and supply chain disruptions influence IPO valuations, as seen in 2026’s muted tech sector activity.
How Saudi Aramco’s IPO Set a Benchmark
Saudi Aramco’s 2019 IPO, priced at $32 per share, raised $29.4B, making it the largest in history. The deal was fueled by the kingdom’s Vision 2030 reforms and a $11.7B EBITDA in 2018. Despite its scale, the stock underperformed post-IPO, closing 18.3% below the offering price by 2023.
“The Aramco IPO was a geopolitical statement, not a purely financial one,” says Chris Whalen, founder of Institutional Risk Analytics. “Its true value lies in its role as a stabilizer for the Saudi economy.”
The IPO’s structure, with 1.5% of the company offered to the public, highlighted the kingdom’s cautious approach to privatization. However, its impact on global energy markets was profound. The influx of capital enabled Saudi Aramco to invest $150B in upstream and downstream projects, indirectly influencing oil prices and OPEC+ dynamics. Bloomberg noted that the IPO’s success hinged on geopolitical stability, a factor still relevant in 2026.
Alibaba’s 2014 Debut: A Tech Titan’s Genesis
Alibaba’s 2014 IPO raised $25B, making it the largest in U.S. History at the time. The e-commerce giant, then valued at $250B, leveraged the Chinese middle class’s rise and digital payment adoption. By 2025, Alibaba’s revenue hit $126.8B, with a 22.4% EBITDA margin.
“Alibaba’s IPO was a watershed for global venture capital,” says Ray Dalio, Bridgewater Associates. “It demonstrated the scalability of China’s tech sector, attracting $50B in follow-on investments.”
The listing also triggered regulatory scrutiny, culminating in the 2020 antitrust fines and the suspension of Ant Group’s IPO. This highlights the tension between rapid growth and regulatory oversight, a theme echoed in 2026’s tech sector. Wall Street Journal analysis underscores how Alibaba’s post-IPO trajectory mirrors broader shifts in China’s economic priorities.
The 2026 Context: IPOs in a Volatile Climate
Current macroeconomic conditions—rising interest rates, inflation, and supply chain bottlenecks—have tempered IPO activity. In 2026, the average IPO size fell 34% from 2023 levels, per Reuters. However, energy and renewables sectors saw a 12% increase in fundraising, reflecting the global push for decarbonization.
For instance, Equinor (OSE: EQNR) raised $4.2B in its 2025 IPO, capitalizing on North Sea oil reserves and offshore wind projects. This aligns with the European Union’s Green Deal, which mandates a 55% emissions reduction by 2030.
“The energy transition is redefining IPO priorities,” says Christina Henderson, head of ESG research at JPMorgan. “Companies that align with sustainability goals are commanding higher valuations.”
