Chicago Lateral Partner Market 2026: Firms Promote More Than Most

The Chicago lateral partner market did not follow the national upswing this year. Sartori & Partners data show 159 lateral partners joining Chicago firms in the 12 months to September 2026, against 163 in the 12 months before: partner hiring held flat (-2.5%). Over the same windows, partner moves across the market rose 8.4%. Chicago firms did not stop adding partners. They made more of them internally. For a firm planning a partner hire in the city, that changes who is movable, what an offer is measured against, and how long the search will take.

The national gain is clear; Chicago's movement is not. Across the market, lateral partner arrivals went from 3,558 to 3,858, and all-level arrivals rose 9.0%. Chicago's all-level count moved from 548 to 601, a shift of 9.7% that stays inside the noise of the two counts, so we read it as flat as well. Partners made up 26.8% of Chicago's lateral moves over the latest 12 months, against 27.7% in the market. New York's partner arrivals were flat too, a change of 3.7%, and Toronto's 15.2% dip on a much smaller base also reads as flat.

By start year, Chicago added 171 lateral partners in 2025 after 125 in 2024, so this year's flat reading follows a step up rather than a slump. A flat partner market after a strong year means fewer partners are already in motion. Most candidates for a Chicago partner seat this year will have to be approached, not found on the move, and the timetable you give your partnership should allow for that.

In the Sartori & Partners lateral database, Chicago firms made 145 lawyers partner in the 12 months to May 2026, 4.9% of all partner promotions in the market. Measured against their own lateral partner hiring, Chicago firms promoted 0.94 lawyers to partner for every lateral partner they brought in. The market runs at 0.79 and New York at 0.76, close to the market rate.

Among the eight cities in the table, only Toronto, at 2.09, promotes more partners per lateral hire than Chicago. Atlanta, at 0.90, sits just below Chicago and Boston, at 0.81, further back. Washington, at 0.67, and Los Angeles, at 0.49, hire more lateral partners than they promote. For a hiring firm, the consequence is direct: a Chicago senior associate or counsel weighs any approach against a credible promotion at home, so the pool of near-partners willing to move is smaller than the city's size suggests.

Promotion in Chicago also comes sooner. Over five years of promotions, new partners in Chicago took 10.2 years on average to make partner, against 11.3 years in New York. The median is the same as New York's, 10.0 years. The difference sits at the edges: the fastest quarter of Chicago's new partners got there within 8.0 years, against 9.0 years in New York, and the slowest quarter took more than 11.0 years, against 13.0 years.

Lateral behavior fits that picture. Only 8.4% of Chicago lateral moves came with a higher title, against 12.9% in the market and 11.6% in New York, which is consistent with a home track that delivers the title without a move. A promise of partnership is therefore a weak lever in a Chicago search. The candidate can usually see their own promotion date, so the offer has to win on platform, client reach or pay.

Chicago's lateral hiring is about as concentrated as New York's, in a far smaller city. Sartori & Partners data show the top 10 hirers in Chicago, listed below, took 21.2% of the city's lateral arrivals at all levels over 12 months, against 21.5% in New York and 62.0% in Toronto. Across the whole market the top 10 took 12.9%, so Chicago is 1.6 times as concentrated as a market that spans every city. In all, 148 firms hired laterally in Chicago, against 310 in New York.

Even so, most Chicago hiring happens outside the top 10, so a candidate in the city seldom faces one dominant bidder. Expect several parallel conversations, move quickly once interest is clear, and build the pitch around your platform rather than around outbidding a single rival.

Chicago's partner mix departs from the market in four practices. Product liability and torts shows the widest gap: it took 13.1% of Chicago lateral partner moves, an index of 195 against the market's own share. Private equity accounted for 17.5% of Chicago lateral partner moves, an index of 144. Employment and labor took 13.1%, index 151, and intellectual property 12.5%, index 136. Litigation, at 41.2%, and corporate and M&A, at 21.2%, sit close to their market shares.

The product liability tilt is not only a partner story: at all levels its share of Chicago hiring is 10.1%, against 6.8% in the market. Banking runs the other way: at all levels it took 12.9% of Chicago moves, an index of 93, while banking partners made up 24.9% of New York's partner moves. A product liability, private equity or employment partner search in Chicago competes with rivals building the same benches, so expect counter-offers and price the package for them. A banking partner search starts from a smaller local share than New York offers.

Relocation runs in Chicago's favor, though at a modest scale. Over 12 months, 78 lawyers at all levels moved to a Chicago firm from another city and 59 left Chicago for one, a net gain of 19. New York ran the other way, with 189 arrivals from other cities against 248 departures. Changing city is still the exception: 15.7% of Chicago lateral moves involved one, against 20.5% across the market. A Chicago partner search is mostly local, but the net inflow shows that lawyers elsewhere will take the move. For a thin practice, put out-of-town partners on the list from the start rather than as a fallback.

Plan for a passive pool. Partner arrivals were flat at 159 against 163, so the strongest candidates are rarely in motion and the first approach has to carry the whole case for the move.

Compete with the internal track, not only with other firms. At 0.94 promotions per lateral partner and a quicker clock than New York's, a near-partner in Chicago compares your offer with a promotion they can date. Sitting partners who already hold the title and want a different platform are the more realistic target.

Expect several bidders and no dominant one. With 148 firms hiring laterally in the city over 12 months, speed and a clear platform case count for more than outbidding a single rival.

Set the brief by practice. Product liability, employment and private equity partner searches are crowded, at an index of 195 for product liability alone; banking draws a lighter local share. Where the local bench is short, widen the search to other cities early, since Chicago takes in more relocating lawyers than it loses.
