Goldman Sachs and Houlihan Lokey emerged as the preeminent financial advisors in the mergers and acquisitions (M&A) arena during the first half of 2026, according to the latest league table compiled by GlobalData. Goldman Sachs commanded the top position in terms of deal value, advising on transactions totaling a staggering $597.4 billion, while Houlihan Lokey secured the lead in deal volume, successfully navigating 152 distinct M&A engagements. This performance highlights a dynamic period in the global M&A market, characterized by significant high-value transactions and a sustained level of advisory activity.
H1 2026 M&A Advisory: A Tale of Two Leaders
The first half of 2026 witnessed a robust display of advisory prowess, with investment banks and advisory firms playing a crucial role in facilitating corporate growth and strategic realignments. GlobalData’s Financial Deals Database, a comprehensive repository of M&A activity, provided the foundational data for this influential ranking.
Goldman Sachs: Dominance in Deal Value
Goldman Sachs’ commanding lead in deal value underscores its strategic involvement in some of the largest and most complex M&A transactions of the period. The $597.4 billion in advised deals signifies a significant uptick in the scale of engagements for the venerable investment bank. This performance is particularly noteworthy when compared to the preceding year, as analyst commentary suggests a substantial increase in the value of deals advised upon.
Aurojyoti Bose, GlobalData’s lead analyst, commented on this remarkable surge, stating, "Goldman Sachs saw the total value of deals it advised on more than double during H1 2026 compared to H1 2025 due to its involvement in big-ticket deals." This increase is not merely incremental; it represents a strategic pivot or a period of exceptional deal-making success. The analyst further elaborated, "Resultantly, it went ahead from occupying the third position by value in H1 2025 to top the chart by this metric in H1 2026." This leap from third to first place is a testament to the firm’s ability to attract and execute mega-deals, often involving cross-border transactions or significant industry consolidations.
The data further substantiates this claim: during H1 2026, Goldman Sachs advised on $61 billion in deals, which included 20 mega deals valued at more than $10 billion each. These large-scale transactions, often the result of extensive due diligence, intricate negotiations, and complex regulatory approvals, are the hallmarks of sophisticated investment banking. The ability to secure and successfully close such deals is a key indicator of an advisor’s market influence and strategic capabilities.
Houlihan Lokey: Sustained Volume Leadership
In parallel, Houlihan Lokey demonstrated exceptional consistency and breadth in its advisory services, leading the pack in the number of M&A deals executed. With 152 deals under its belt, the firm has solidified its reputation as a go-to advisor for a high volume of transactions. This achievement marks a continuation of its previous success, as Bose noted, "Houlihan Lokey was the top adviser by volume in H1 2025 and managed to retain its leadership position by this metric in H1 2026 as well."
This sustained leadership in volume suggests a strategic focus on a diverse range of clients and deal sizes, potentially spanning mid-market to larger enterprises. A high volume of deals often indicates strong client relationships, efficient deal execution processes, and a broad market reach. For companies seeking M&A advisory, a firm with a proven track record of handling numerous transactions can offer invaluable experience and a streamlined approach, particularly for those engaging in their first or second M&A activities.
Key Players in the M&A Advisory Arena
While Goldman Sachs and Houlihan Lokey occupied the top spots, other prominent financial institutions also demonstrated significant M&A advisory capabilities in the first half of 2026.
Morgan Stanley: A Strong Contender in Both Metrics
Morgan Stanley proved to be a formidable competitor, securing the second position in the value ranking with a substantial $420 billion in advised deals. Its presence at the top tier across both value and volume metrics highlights its comprehensive M&A advisory services. The firm also captured the second spot in the volume ranking, advising on 122 deals, underscoring its broad engagement across the M&A landscape.
JPMorgan Chase: Significant Deal Value and Volume
JPMorgan Chase also made a strong showing, ranking third in the value table with $382.2 billion in advised transactions. Its advisory efforts extended to 90 deals, positioning it as a significant player in both the financial scale and the sheer number of M&A activities it facilitated.
Other Notable Advisors
The league tables further revealed the significant contributions of other major financial institutions. Bank of America followed JPMorgan Chase in the value ranking with $230.4 billion, while Wells Fargo secured the fifth position with $208.9 billion. In the volume ranking, after Morgan Stanley and Goldman Sachs, JPMorgan Chase was followed by Evercore, which advised on 81 deals, indicating its strong presence in specialized advisory services or its focus on specific market segments.
Analyzing the Trends: What Drives M&A Advisory Success?
The performance of these leading advisory firms in H1 2026 can be attributed to several key factors:
- Expertise in Mega-Deals: Goldman Sachs’ leap in value is directly linked to its involvement in large-scale transactions. This suggests a continued trend of industry consolidation, cross-border mergers, and strategic acquisitions by major corporations seeking to expand market share, acquire new technologies, or achieve economies of scale. Such deals often require deep industry knowledge, intricate financial structuring, and sophisticated negotiation skills, areas where established investment banks excel.
- Mid-Market Focus and Efficiency: Houlihan Lokey’s sustained volume leadership points to its strength in serving a broader market, likely including a significant portion of mid-market M&A. This segment of the market is often characterized by a higher frequency of transactions, as companies at this stage of growth frequently engage in acquisitions to expand or divest non-core assets. A high volume of deals implies efficient deal execution, a robust network of clients, and specialized teams capable of managing multiple mandates simultaneously.
- Broader Market Dynamics: The overall M&A landscape in H1 2026 appears to be robust. The sustained activity, particularly in high-value transactions, suggests a favorable economic environment for corporate expansion and strategic repositioning. Factors such as readily available financing, investor confidence, and the pursuit of synergies are likely contributing to the ongoing M&A momentum.
- Technological Integration and Data Analytics: While not explicitly detailed in the provided data, it is reasonable to infer that leading advisory firms are increasingly leveraging advanced data analytics and technological tools to identify M&A opportunities, conduct due diligence more efficiently, and provide clients with more precise market insights. GlobalData’s own methodology, which involves real-time tracking and data submissions, reflects this increasing reliance on sophisticated data management.
GlobalData’s Methodology: Ensuring Data Integrity
GlobalData’s league tables are built upon a rigorous and comprehensive data collection process. The firm’s analysts meticulously monitor thousands of company websites, advisory firm websites, and other reliable secondary sources to capture real-time M&A activity. A dedicated team is responsible for gathering in-depth details for each deal, including the names of the advisors involved. To further enhance the robustness and accuracy of its data, GlobalData actively seeks submissions of deals from leading advisory firms. This multi-pronged approach ensures that the resulting league tables provide a reliable and authoritative snapshot of the M&A advisory market.
Implications for the Market and Beyond
The results of the H1 2026 M&A advisory league tables carry several implications:
- Competitive Landscape: The continued dominance of established bulge-bracket firms like Goldman Sachs and Morgan Stanley in high-value deals, alongside specialized advisors like Houlihan Lokey excelling in volume, highlights the segmented nature of the M&A advisory market. Different firms cater to different needs and client bases, each with its unique strengths.
- Strategic Importance of Advisory Services: The significant value of advised transactions underscores the critical role financial advisors play in shaping corporate strategy, facilitating growth, and driving economic activity. Their expertise is indispensable in navigating the complexities of M&A.
- Future Market Trends: The sustained M&A activity suggests a continued appetite for corporate transactions. This could be driven by technological disruption, the need for greater scale, or the pursuit of new market opportunities. Advisory firms that can adapt to evolving market conditions and client needs will likely continue to thrive.
- Economic Indicator: M&A activity is often seen as a barometer of economic health and corporate confidence. The robust performance in H1 2026 suggests a positive outlook for the global economy and a willingness among businesses to invest in strategic growth.
As the M&A landscape continues to evolve, the performance of financial advisors will remain a key indicator of market trends and corporate ambitions. The strong showing by Goldman Sachs and Houlihan Lokey in the first half of 2026 sets a clear benchmark for the rest of the year, indicating a dynamic and active M&A environment driven by both strategic mega-deals and consistent deal-making across a broader spectrum of the market. The ability of these firms to adapt to changing economic conditions, regulatory environments, and technological advancements will be crucial in maintaining their leadership positions in the years to come.
