Investment Banking Services in 2026: Fees, M&A and IPO Data
Investment Banking Services in 2026: What the Fee and Deal Data Actually Show
A look at how M&A advisory, capital markets underwriting and IPO activity are trending in 2026, drawn from bank-reported and third-party deal data rather than marketing claims.
As of mid-2026, investment banking activity is running well ahead of 2025. Global banking fees reached $79.9 billion in the first half of the year, up 17% year-over-year, according to LSEG Data & Analytics, with debt underwriting the single largest fee category. Global M&A volume hit roughly $2.73 trillion year-to-date per Dealogic, and global IPO proceeds nearly tripled to $186.8 billion in the first half, though the number of IPOs actually fell — meaning a handful of very large transactions, not broad-based activity, are driving most of the headline growth.
Investment banking headlines tend to swing between "boom" and "bust" narratives every year, but the underlying activity is easier to read through actual fee and deal-volume data than through sentiment alone. Halfway through 2026, that data points to a genuine rebound in dealmaking, concentrated capital markets activity, and an IPO market that looks stronger in dollar terms than it does in the number of companies actually going public.
1. What Investment Banking Services Cover
"Investment banking" is a broad label that covers several distinct service lines, and understanding the split matters because each one behaves differently across the economic cycle. Mergers and acquisitions (M&A) advisory involves helping a company buy, sell, merge with, or defend against another company, typically in exchange for a fee tied to the deal's value. Capital markets services split into equity capital markets (ECM), which covers stock issuance such as IPOs and follow-on offerings, and debt capital markets (DCM), which covers bond issuance and syndicated loans.
Beyond those two pillars, many banks also offer leveraged finance (financing for private-equity-backed acquisitions), restructuring advisory (for financially distressed companies), and risk management or hedging services tied to interest rates, currencies or commodities. Large global banks such as Goldman Sachs, JPMorgan and Morgan Stanley operate across all of these lines, while boutique advisory firms — Lazard, Evercore and Moelis & Company among them — tend to concentrate on M&A and restructuring advisory without the balance-sheet-heavy underwriting business.
The distinction matters for corporate clients: a full-service bank can bundle advisory work with financing, which can be efficient but also raises potential conflicts of interest, while a boutique's advice is not tied to selling its own balance sheet products.
2. M&A Advisory Activity in 2026: The Data
Global M&A volume reached roughly $2.73 trillion in the year to date as of mid-2026, a 38% increase year-over-year, according to deal-tracking data reported via Dealogic. That builds on an already strong 2025, when full-year global M&A climbed 42% year-over-year to $5.1 trillion and total investment banking revenue topped $100 billion — the second-highest annual total on record.
Activity has been notably concentrated among the largest banks. Reported figures show Goldman Sachs advising on more than $1 trillion of announced M&A so far in 2026, representing over 40% of total announced global deal value and a 71% increase from the same period a year earlier. JPMorgan and Morgan Stanley followed, with reported advised volumes of roughly $687.5 billion and $575.9 billion respectively. Executives at both firms have pointed to accelerating pipelines: Goldman Sachs CEO David Solomon described conditions as "incredibly constructive" for M&A and capital markets on a call with analysts, while Morgan Stanley's finance chief flagged healthcare and industrials as areas of expected pickup.
Regionally, the pattern is uneven. In the U.S. and Canada, the number of public M&A deals rose about 8% year-over-year in the first half of 2026, but total disclosed deal value fell as large-cap transactions became less frequent. In Europe's financial-services sector specifically, deal count held roughly steady while disclosed value dropped sharply — a reminder that deal count and deal value do not always move in the same direction, and headline "M&A is booming" statements can mask very different stories depending on sector and geography.
| Bank | Reported Advised M&A Volume (2026 YTD) | Approx. Share of Global Volume |
|---|---|---|
| Goldman Sachs | $1,000B+ | >40% |
| JPMorgan | $687.5B | ~25% |
| Morgan Stanley | $575.9B | ~21% |
Figures reflect announced (not necessarily completed) deal volume as reported via Dealogic data; shares are approximate and reflect overlapping advisory roles on the same transactions, so totals will not sum to 100%.
3. Capital Markets: Debt and Equity Underwriting Trends
Underwriting — helping companies and governments raise money by issuing stocks or bonds — makes up the other major pillar of investment banking revenue. In the first half of 2026, debt capital markets generated the largest share of global banking fees at $25.2 billion, up 8% year-over-year, according to LSEG. That reflects continued heavy corporate bond issuance as companies term out debt and refinance ahead of anticipated rate moves.
Equity capital markets fees also grew, supported by a wave of large initial public offerings and follow-on share sales (discussed in the next section). Taken together, LSEG reported that all three major fee categories — equity issuance, debt underwriting, and M&A advisory — rose in the first half of 2026 compared with the same period a year earlier, with second-quarter fees running about 6% ahead of the first quarter.
For corporate treasurers and CFOs, the practical takeaway is that financing windows have been comparatively open in 2026: issuers with solid credit profiles have generally been able to access debt and equity markets, though pricing and appetite still vary significantly by sector and credit rating.
4. The 2026 IPO Market Recovery — and Its Limits
The IPO market illustrates why headline dollar figures can be misleading without deal-count context. Global IPO proceeds in the first half of 2026 roughly tripled year-over-year to about $186.8 billion, according to EY's IPO Barometer — the highest quarterly issuance volume EY has recorded since it began tracking the data in 2003. Yet the number of companies that actually went public fell to 483, down from 546 in the first half of 2025, a 12% decline.
The gap between "deal count down, dollars up" is explained largely by a small number of enormous listings. A single U.S. IPO accounted for roughly $86.2 billion of proceeds in the second quarter alone — described by EY as the largest IPO of all time — pushing U.S. IPO issuance volume from about $17.1 billion to $128 billion year-over-year even as the number of U.S. listings fell. China's IPO proceeds also grew strongly, roughly tripling to $35.8 billion, while Europe's issuance volume rose more modestly to about $9.2 billion.
The practical implication for companies weighing a public listing: 2026's IPO market has rewarded large, well-capitalized issuers with strong investor demand, while smaller or mid-cap candidates have continued to face a more selective, "prove it first" environment. EY's own analysis frames this as a structural, tech-heavy recovery rather than a broad-based reopening of the IPO window.
5. How Investment Banks Are Selected and Paid
Companies typically choose an investment bank based on sector expertise, relevant deal-size experience, existing relationships, and — for capital markets work — a bank's distribution reach among institutional investors. Larger, full-service banks are often chosen for their ability to combine advisory work with balance-sheet commitments such as bridge financing; boutique advisory firms are more often chosen specifically because they do not have lending relationships that could create a conflict of interest.
Fee structures vary by service line but follow recognizable patterns. M&A advisory fees are generally contingent on deal completion and calculated as a percentage of transaction value on a sliding scale — often higher, proportionally, for smaller deals and lower for very large ones. Underwriting fees for stock or bond offerings are typically a percentage of the amount raised, sometimes called the underwriting spread or gross spread, and are usually split among a syndicate of banks working on the offering rather than paid entirely to one firm.
Engagement letters generally specify whether the bank has exclusivity, how "success" is defined for fee purposes, and what happens if a deal is announced but does not close — details that matter considerably more to the outcome than headline league-table rankings.
6. Risks and Considerations for Corporate Clients
- Conflicts of interest — A bank that both advises on a sale and offers financing to the buyer has competing incentives; independent fairness opinions and clear engagement-letter terms help manage this.
- Fee-timing mismatches — Because most advisory fees are contingent on closing, banks may be incentivized to push a deal toward completion even where terms have shifted unfavorably for the client.
- Market-window risk — As the 2026 IPO data shows, favorable pricing windows can close quickly; companies preparing to raise capital generally build in flexibility around timing.
- Concentration risk in league tables — A small number of banks handling an outsized share of the largest deals means capacity and staffing can become a genuine bottleneck during peak periods, affecting execution timelines.
- Regulatory and disclosure obligations — Public-company transactions and securities offerings are subject to SEC (or equivalent) disclosure rules; missing procedural steps can delay or derail a transaction independent of market conditions.
7. Frequently Asked Questions
Investment banking services generally span three areas: M&A advisory (advising companies on buying, selling or merging with other businesses), capital markets underwriting (helping companies raise money through stock or bond issuance), and related advisory work such as restructuring, leveraged finance and risk management. Large full-service banks offer all three; boutique firms often specialize in just one, such as M&A advisory.
Dealmaking accelerated through 2026 as corporate and private equity pipelines that had built up during a slower 2022-2024 period began converting into signed transactions, helped by more stable financing costs and improving valuations. A relatively small number of very large transactions accounted for a disproportionate share of the total value increase, which is a recurring pattern in strong M&A years.
Not entirely. EY's first-half 2026 data shows the number of IPOs globally actually fell compared with the first half of 2025, even as total proceeds roughly tripled. That divergence means a handful of very large listings, rather than a broad wave of smaller companies going public, drove most of the dollar growth.
Compensation varies by service line. M&A advisory fees are generally contingent on a transaction closing and are calculated as a percentage of deal value, often on a sliding scale. Underwriting fees for stock or bond offerings are typically a percentage of the amount raised, known as the underwriting spread or gross spread.
Relevant considerations include the bank's track record in the specific sector and deal size, potential conflicts of interest if the bank also represents competitors or counterparties, the balance between a large full-service bank's distribution reach and a boutique firm's specialized focus, and a clear understanding of the fee structure and any exclusivity terms in the engagement letter.
