Fintech M&A Counsel in 2026: Corporate Lawyers on 45.4% of Deals

A general counsel at a payments company or a digital lender who is weighing fintech M&A law firms should start from one fact: in this sector the corporate bench carries an unusual share of the work. Sartori & Partners data show 493 fintech and payments deals on record in the 12 months to October 2026, and corporate and M&A lawyers worked on 224 of them, or 45.4%. Across all 48,131 dated deals the same practice reached 23.3%. The sector is small, at 1.0% of all dated deals, but corporate lawyers sit on its files far more often than on the market's. This report sets that over-weight against the deal mix, ticket size, the cities where the work is done and the year's direction, and ends with what it means for the next mandate.

The ratio of the two shares is the central number: corporate and M&A lawyers were on 1.9 times as large a share of fintech deals as of all dated deals, a gap of 22.1 points. The contrast with banks, the sector closest to fintech, is sharper still. Corporate lawyers worked on only 13.1% of bank and financial institution deals, where capital markets lawyers dominate at 51.0%. In fintech the capital markets practice reached 23.7%, close to its 26.4% across the market. Financial services regulatory lawyers appear on 5.9% of fintech deals, against 0.5% of all deals, a reminder that licensing questions follow these companies into their transactions. One deal can carry several practices, so the shares overlap and are not added. A deal here is a matter on record, court and trademark filings included, not a measure of fees. For a company, the reading is simple: a fintech mandate is first a corporate mandate, and the corporate partner, not the capital markets or banking partner, is the person to test hardest at the pitch.

By deal type, M&A was the largest category in fintech and payments at 29.4% of the sector's deals, ahead of capital markets at 21.9% and disputes and investigations at 15.0%. The market's order is different: capital markets at 25.7%, disputes at 25.0%, and M&A third at 19.3%. Among bank deals, M&A was just 11.6%. Corporate lawyers' share of fintech deals runs above the M&A type share, so their work in the sector reaches past deals typed as M&A into other categories and into deals that carry no type at all. That matches the practice as a whole, where M&A was 74.6% of corporate and M&A deals and the rest spread across other types. These shares are of all dated deals and some deals carry no type, so they do not form a complete split. For a buyer, the point is that fintech counsel should be judged on transactions first; a firm whose fintech record is mostly disputes or offerings is a different proposition.

Where a value was disclosed, the median fintech and payments deal was $237.9 million, against $315 million for corporate and M&A deals across every sector. Bank and financial institution deals sat far higher, at a median of $660 million. Disclosure itself is more common in fintech: a value was published on 32.0% of the sector's deals, against 17.7% of corporate and M&A deals, so the fintech median rests on a wider base. The comparison is median against median and says nothing about the largest deals in either group. For a general counsel, a smaller typical ticket inside a heavily corporate sector has two consequences. Fee proposals should be sized to the deal rather than to a large-cap template, and a mid-sized team with fintech experience can be the right fit where a firm built for the largest transactions would be over-staffed.

Sartori & Partners data place the lawyers on fintech deals mostly in New York, which appeared on 43.6% of the sector's deals with a known lawyer location, against 36.8% of bank deals. London follows at 18.4%, level with Washington, DC at 18.4%, and London's share runs above its 16.0% of bank deals. The West Coast shows up as well: San Francisco lawyers worked on 13.7% of fintech deals and Palo Alto lawyers on 9.3%. Paris, at 6.3%, is the only continental European city in the sector's list. One deal can count in several cities, so these shares overlap and describe where the work is done, not how many lawyers sit there. A company with a European angle to its deal should ask early whether the London team is part of the core group or a referral office.

Year on year, the fintech and payments deal count held flat (-3.8%), at 487 deals in the latest settled 12 months against 506 a year earlier. Over the same windows the corporate and M&A deal count rose 9.5%, at 11,170 against 10,198, and the deal market as a whole rose 10.6%. In the Sartori & Partners lateral database, the count of corporate and M&A lateral moves rose 15.8%, at 2,933 against 2,532. Those are moves of lawyers between firms, not deals, and they sit beside the fintech count without explaining it. What the three lines together suggest for a company is a timing issue: the corporate partners who handle fintech work are busier on other sectors' deals than a year ago, while the fintech pipeline itself has not grown. Book the team before signing a term sheet, and confirm in the engagement letter which named lawyers stay on the file.

Neither list below is a ranking for fintech M&A, and no list for the pair is published. The fintech list ranks firms by all the sector's deals on record, capital markets and disputes included; the corporate and M&A list ranks firms by all the practice's deals in every sector. Counted name by name, five firms sit in the top 10 of both lists: Latham & Watkins, Wilson Sonsini Goodrich & Rosati, White & Case, Fenwick & West and DLA Piper. The first firm on the fintech list sits in the 41-60 band of sector deals, against the 401-700 band for the first firm across corporate and M&A, a measure of how small the sector is next to the practice. A shortlist that starts from the overlap and then asks each firm for its fintech transactions, team by team, avoids mistaking sector volume for corporate depth.

Four points follow. First, hire a corporate team: corporate and M&A lawyers were on 45.4% of fintech deals, 1.9 times their market share, so the corporate partner's fintech record matters more than the firm's brand in finance. Second, keep regulatory cover in the room, with financial services regulatory lawyers on 5.9% of sector deals. Third, price to the ticket: the median disclosed fintech deal, at $237.9 million, sits below the practice's $315 million. Fourth, check London if the deal crosses the Atlantic; London lawyers were on 18.4% of fintech deals with a known location. Sartori & Partners data, drawn from public law-firm announcements, firm websites and professional profiles, checked monthly, will show in the next edition whether the level fintech count turns.
