Corporate M&A Lateral Hiring Rose 15.8%, Faster Than the Market

Corporate M&A lateral hiring is running ahead of the legal market as a whole. Sartori & Partners data show 2,933 corporate and M&A lawyers joining a new firm in the settled 12 months to September 2026, up from 2,532 in the year before, a rise of 15.8%. Across every practice, lateral moves rose 9.0%, from 13,128 to 14,305. For a firm planning its next corporate hire, that gap means more rivals for the same candidates, at partner level as much as below it.

Corporate and M&A lateral moves rose 15.8% in the settled year to September 2026, 1.8 times the market's rate. In absolute terms that is 401 more corporate moves than in the prior settled year. The practice now holds 20.7% of all lateral moves, second only to litigation at 39.9%. Litigation grew 7.5% over the same windows, so the corporate rise is specific to transactional work rather than a tide lifting every practice. Private equity, which counts 38.2% of corporate movers among its own, rose 14.9%.

A firm that budgeted a corporate search on last year's pace should expect more competing offers and a shorter window between first meeting and signed terms.

Juniors did not carry the growth on their own. Corporate partner arrivals rose 12.2%, from 778 to 873, while partner moves across all practices rose 8.4%. In litigation, the largest practice, partner hiring was flat, with a change of 0.9%. Private equity partner hiring grew faster still, at 16.1%, but on a base of 469 partner moves against 873 in corporate.

The level mix sits close to the market. Partners were 29.9% of corporate laterals in the 12 months to October 2026, against 27.7% across all practices, and associates 57.7% against 58.5%. Partner volume climbed every year from 2023 to 2025: 619 that year, 668 in 2024 and 789 in 2025. By October 2026 the count had reached 787, already close to the full 2025 total.

For a firm seeking a corporate partner, this is a seller's market that has not yet turned. More firms are bidding than a year ago, and candidates know it: expect to compete on role and platform, not only on pay.

In the Sartori & Partners lateral database, corporate moves fell from 2,514 in 2022 to 1,895 in 2023, a year that ran at 75.4% of the 2022 level. The market as a whole held 86.2%. Corporate hiring then rose to 2,247 in 2024 and 2,594 in 2025, above its 2022 volume. By October, the 2026 count stood at 2,617, past the full 2025 total; the market, at 12,554, had not yet reached its 2025 count of 13,237.

Corporate hiring swings harder than the market in both directions. A firm that adds corporate partners only in strong years pays the highest price for them. The 2023 dip shows when the competition thins: in a slow deal year, fewer firms are bidding, and a patient firm gets a wider choice.

Where corporate lawyers land is tilted toward size. Firms of 1,000+ lawyers took 62.6% of corporate laterals with a known firm size in the 12 months to October 2026, against 53.6% across the market and 43.3% in litigation. Firms of 150-399 lawyers took 8.7% of corporate moves, against 13.3% market-wide.

Partner hiring is concentrated in the same way. The ten most active corporate partner hirers took 20.9% of corporate partner moves, against 13.5% for the ten most active partner hirers across the market. White & Case, DLA Piper, Simpson Thacher & Bartlett and Greenberg Traurig sit in the 21-40 band of corporate partner hires. Reed Smith and Holland & Knight make this partner list without appearing among the ten most active corporate hirers at all levels.

A firm below the largest size class competes against guarantees it may not match. Its case has to rest on fit: a practice the candidate can lead, clients that are not conflicted out, and a role the largest firms will not offer.

Lateral moves are only one exit from a corporate team. Since May 2026, Sartori & Partners data show 316 corporate and M&A lawyers leaving a law firm for an in-house role, equal to 20.1% of the practice's lateral moves over the same months. In litigation the figure is 12.3%, and across all practices 13.1%. Corporate lawyers go in-house at 1.6 times the litigation rate. Private equity, for all its overlap with corporate work, sits at 11.4%. Company legal teams hire transactional lawyers to run deals from the inside, and that route stays open in a busy year.

For a firm, this is a retention cost as much as a recruiting one. A corporate team sees departures to companies on top of departures to rival firms, so succession and replacement plans should assume a higher outflow than a disputes team of the same size. The measure starts in May 2026, so there is no earlier year to compare.

Hire into the rise rather than waiting it out. Corporate moves grew 15.8% against 9.0% for the market, and partner moves grew 12.2%: a calmer quarter is unlikely to bring fewer bidders. Expect the largest firms in most processes, since 62.6% of corporate moves ended at firms of 1,000+ lawyers.

Search across the adjacent benches. Of corporate movers, 38.2% also work in private equity and 12.5% in banking and finance, so a corporate mandate can draw on candidates who carry another label. Weigh the city too: Houston takes 3.2% of corporate arrivals against 2.3% of all moves, and Boston 3.3% against 2.6%, while Washington takes 2.9% against 5.6%. And budget for retention: with in-house moves at 20.1% of lateral moves, the team a firm builds will lose people to clients faster than a litigation group would.
