Mordor Intelligence has published a new report on the US investment banking market, offering a comprehensive analysis of trends, growth drivers, and future projections

US Investment Banking Market Outlook

According to Mordor Intelligence, the US investment banking market is expected to grow from USD 54.74 billion in 2025 to USD 56.68 billion in 2026, and is forecast to reach USD 67.47 billion by 2031, registering a CAGR of 3.55% during the forecast period. The market size reflects steady expansion supported by sponsor-led mergers, a stabilizing IPO calendar, and expanding advisory mandates across infrastructure, energy-transition, and diversified sectors including BFSI, technology, manufacturing, and even auto and car financing-related corporate transactions.

The industry is navigating a period defined by higher policy rates, tighter capital rules, and rising competition from private credit. Even so, market growth continues to be supported by advisory resilience, capital solutions desks, and deeper client wallet share. As banks rebalance their models toward advisory-heavy structures and selective underwriting, the market forecast points to moderate but durable expansion.

US Investment Banking Market Growth Drivers

Sponsor-Led M&A Supporting Fee Pools

A major driver of US investment banking market growth is sponsoring mergers and acquisitions. Large pools of private equity capital continue to seek deployment opportunities, sustaining advisory mandates even amid rate volatility. Mega-cap and large-cap transactions remain central to the US investment banking market share, particularly where integration complexity and cross-border structuring demand experienced advisors. Club deals, sector-focused acquisitions in technology and healthcare, and consolidation across manufacturing and energy continue to generate advisory spreads. Banks with strong sector expertise and balance sheet flexibility are better positioned to defend pricing and protect margins within the US investment banking industry.

Debt Advisory in a High-Rate Environment

Elevated interest rates have changed refinancing strategies across corporate America. Liability management, covenant restructuring, ESG-linked refinancing, and hybrid securities issuance have increased demand for structured advisory services. This shift is reshaping US investment banking market trends, where debt advisory plays a stabilizing role even as leveraged finance volumes soften. Banks that combine derivatives, private credit placements, and bond issuance within one proposal are expanding their market share. Debt's advisory has become a cross-selling gateway that strengthens long-term enterprise relationships.

Energy-Transition and Infrastructure Financing

Federal incentives and clean energy funding programs have expanded financing mandates across renewable power, grid modernization, and climate-related infrastructure. This has created sustained activity within project finance advisory, green bonds, and structured credit. As infrastructure pipelines expand, the US investment banking market forecast benefits from recurring financing needs in energy corridors across multiple states. Dedicated clean-energy teams are becoming common across the US investment banking industry, helping banks secure repeat mandates and diversify revenue beyond traditional M&A cycles.

IPO Pipeline Recovery in Technology and Healthcare

After a period of slower issuance, the IPO calendar has shown signs of improvement. Technology, digital health, and biotech issuers are re-entering the public markets as valuation stability improves. Underwriters are prioritizing execution of certainty, often supporting gross spreads in equity capital markets. Private equity exits and venture-backed listings remain central to US investment banking market trends. A steady IPO pipeline reinforces equity capital markets revenue and supports broader market growth over the forecast period.
