The big story going into May was the planned combination of Chicago-founded Winston & Strawn with Taylor Wessing's UK arm, to be known as Winston Taylor. The deal was announced in December 2025, partners at both firms approved it in January, and completion was expected in May 2026. The combined firm would have more than 1,400 lawyers and around 20 offices across the US, the UK and Europe, plus outposts in Latin America and the Middle East.

The structure is the interesting part. This was not a simple buy-out. Taylor Wessing is a verein, a loose international alliance of member firms, and only some members joined. Taylor Wessing's Netherlands and Belgium offices voted to operate under the Winston Taylor brand. Its German partnership stayed outside the merger, with Winston Taylor agreeing a cooperation and referral arrangement with the legacy Taylor Wessing verein instead. For European lawyers, that is a useful reminder that a "UK firm merger" often means different things in different jurisdictions, depending on who owns what and who has voted.

What it means for sellers. Partners at the firm being absorbed want a platform, not just a price. The pitch in these deals is usually access to US clients, deeper capital markets work and better rates for talent, rather than a cash payout. Partners vote on terms such as equity entry, profit-sharing and brand, so the deal is as much a culture negotiation as a financial one.

What it means for buyers. US firms want London and European reach without building from scratch, and a UK firm with an established client base is a faster route than lateral hiring.

The AI angle. Scale is part of the pitch because technology costs money. Legal tech attracted record investment in 2025, around $4.08 billion, with a further $2.34 billion in the first quarter of 2026, much of it concentrated in a handful of AI platforms such as Harvey and Legora. Larger firms can spread those licence and integration costs across more lawyers. That logic is not always spelled out in a merger announcement, but it is in the background of most of them.

Whether combinations like this deliver more than the sum of their parts will take years to judge. In the meantime, they have become the model that others are measured against.
