AI-Driven Equity Issuance Sets Record in Global Capital Markets During First Half of 2026

In the first half of 2026, the global equity capital markets (ECM) experienced a transformative wave, primarily driven by artificial intelligence-related equity issuance. This period saw a remarkable increase in activity, largely attributed to the historic IPO of SpaceX, which alone accounted for a staggering USD 86.2 billion. According to the latest ECM Highlights report by Dealogic, global ECM issuance reached a monumental USD 729.4 billion, marking an over 73% increase compared to the same period last year.

A Closer Look at the Statistics

The statistics unveil a standout trend in the market, with technology sectors dominating the landscape. These sectors contributed approximately one-third to the overall issuance volume, highlighting the growing reliance on technological advancements in capital markets. Notably, convertible bonds also achieved their highest first-half figures to date, signaling a robust investor appetite for innovative financial products.

The ECM issuance witnessed explosive growth particularly in the Americas, especially in the second quarter, which recorded the highest quarterly value in history. Not only did the SpaceX IPO take center stage, but it also typified the capital momentum largely powered by AI infrastructure expansions and its diversification into broader applications through ventures such as xAI.

Breakdown of Global Issuance

The report highlights that global IPO volumes skyrocketed to USD 207 billion in the first half of 2026, a dramatic leap from USD 68.6 billion recorded during the same period in 2025. The Americas alone accounted for USD 442 billion, showing a 104% year-on-year growth.

Technology maintained its status as the leading sector in the Americas, securing 32% of deal value from these remarkable figures. The second quarter’s ECM performance was particularly notable, with USD 303.8 billion in issuance, trailing only behind the first quarter of 2021, which reached USD 316 billion.

Meanwhile, the EMEA (Europe, the Middle East, and Africa) markets reported a 29% increase in ECM growth in the first half of 2026. This growth was boosted by notable convertible bond transactions and accelerated private equity disposals. However, the United Kingdom’s market lagged with a 14% decrease, grappling with a backlog of prospective IPOs that have yet to materialize into substantial activity.

Asia-Pacific (APAC) markets reflected contrasting dynamics, led by the efforts of China and Hong Kong, which saw over USD 105.2 billion in equity issuance. This represented a 62% year-on-year growth, underscoring the national push to back local AI champions amidst growing global competition in this domain. However, India and Japan faced challenges due to fluctuations in energy prices, primarily instigated by ongoing geopolitical tensions in the Middle East, though there are expectations for a recovery in the latter half of 2026.

Expert Insights and the Road Ahead

Samuel Kerr, Head of Global ECM at Mergermarket EMEA, remarked on the unprecedented deal sizes being observed. According to him, the volume of capital deployed in AI capital expenditure in the first half of 2026 has been extraordinary. While there's an optimistic outlook from investors, there's an unmistakable caution given the historical context of past tech booms and subsequent downturns.

Kerr pointed out that looking ahead, a critical question looms over whether the current capital markets possess the capacity to support the anticipated megadeals arising in the near future. Corporations like Anthropic and OpenAI are poised to enter the market, and their performance could serve as a bellwether for sustained market health.

Conclusion

The first half of 2026 sets a remarkable stage for how AI influences the global equity landscape. With record-breaking numbers and a showcase of innovation within capital markets, the future seems equally promising and precarious as stakeholders navigate the continuing evolution of technology in finance.
