A guide to the top US law firms in London: who they are, what they do and why their rapid growth matters.
One of the biggest trends in the UK corporate law market over the past 10 years has been the ever-increasing dominance of US law firms in London.
It’s no exaggeration to say that the London legal market has undergone a seismic shift in that period.
Once dominated by the Magic Circle and other elite UK firms, the City has become a battleground for US law firms looking to expand their global reach.
With sky-high salaries, aggressive recruitment and a relentless focus on profitability, US firms have transformed the landscape of City law - forcing UK incumbents to adapt or risk losing talent and (most importantly) clients.

US law firms have long had a presence in London - several big names have had London outposts since as far back as the 1970s - but over the past ten years, their expansion has skyrocketed.
Initially, many focused on specialist areas like high-stakes litigation and private equity, but today, many offer full service practices competing directly with UK heavyweights.
A key driver has been the globalisation of legal work and the rapid growth of private capital in financial markets since the global financial crisis in 2008.
With private equity, finance and M&A work growing ever more complex, clients want seamless cross-border representation. Many US firms, already dominant in New York, eyed an opportunity to replicate their success in London which, aside from being a key financial centre in its own right, serves as the ideal gateway to the European market.
For some, this has meant launching offices from scratch. Others have expanded existing bases through strategic lateral partner hires, while others have gone bigger and opted for headline-making transatlantic mergers.
Either way, a natural consequence of American expansion has been the relentless demand for top-tier legal talent.
US firms have lured partners and associates away from the Magic Circle and leading London-based international firms with eye-watering comp packages and salaries - often paying well over £170,000 for newly qualified solicitors.
In an industry where prestige and pay go hand in hand, it’s fair to say this strategy has proven highly effective.

What do City lawyers actually do each day?
For a closer look at the day-to-day of some of the most common types of lawyers working in corporate law firms, explore our lawyer job profiles:
US law firms in London broadly fall into two categories: those that have grown organically and those that have entered via transatlantic mergers.
These firms have expanded into London without merging with a UK firm.
Many started as small outposts operating without English-qualified lawyers (i.e. serving US clients on US law matters abroad) but are now serious players in the London market.

These firms have expanded via headline-grabbing tie-ups with UK firms, creating global giants.

Why does any of this matter?
Well, the growth of US firms is having a transformative effect on the London legal market. Here are some of most important trends:
Salary wars: UK firms have been forced to increase junior lawyer pay to compete, leading to a spiraling salary war, pushing up the fixed costs of firms and putting a squeeze on profits. How sustainable this model proves to be remains to be seen.
Changed firm structures: Many UK firms traditionally operated with lockstep partnership pay models, but almost all have been forced to adapt to retain their top talent and adopt more performance-based structures, moving to so-called “modified lockstep” models. See our guide to corporate law firms to learn more about different partnership models.
The battle for talent: A feature of the London legal market over the past two-three years has been US firms poaching high-profile partner talent from UK and US rivals. Reports of $20 million pay packages for the biggest rainmakers are no longer uncommon. 2023 and 2024 were the busiest years ever for partner hires in London.
Increased competition for clients: Naturally, US firms now regularly go head-to-head with Magic Circle firms for the major deals.
Culture shake-up: The US model of leaner teams, higher billable hour targets and a more transactional mindset has influenced how many City firms operate - at least those that want to directly compete with their new US rivals.
The Magic Circle itself, for example, is now considered to be splintering.
The likes of Freshfields, A&O Shearman and Linklaters are all prioritising growth in the US - Freshfields, in particular, is looking to shake-off its "Magic Circle" label and align itself more closely with the "global elite" dominated by US firms.
Slaughter and May, meanwhile, has long-eschewed international expansion. Many are now questioning the relevance of the "Magic Circle" tag given firms' diverging strategies.

The growth of US firms in London shows no signs of slowing down.
The likes of Paul Weiss, Sidley Austin and Simpson Thacher are expanding aggressively, while firms with bigger London footprints like Kirkland and Latham continue to dominate much high-end transactional work. Meanwhile, UK firms are being forced to rethink their pay structures, firm culture, and strategic positioning in response.
As US firms keep pushing their advantage, the big question is whether the Magic Circle will hold its ground or if we’ll see more transatlantic tie-ups.
Either way, one thing is clear: the London legal market is no longer just a UK stronghold - it’s a transatlantic battleground - and right now US firms seem to be winning the war.
