The Squeezed Middle: Why the Consulting Market Is Splitting in Two

If you run an advisory practice, the most important thing happening to your market right now isn't a competitor or a client. It's a shape. The consulting industry is splitting into two distinct tiers, and the space in the middle – where a great many firms currently sit – is quietly disappearing. Understanding that shape is the difference between riding a structural change and being slowly crushed by one.

Let me lay out what's actually happening, because the trend lines have been building for a couple of years and 2026 is the point where they became hard to ignore.

A market pulling apart at both ends

AlphaSense, a market-intelligence firm that tracks the consulting industry closely, describes the sector in 2026 as moving toward a two-tier structure. At the top, heavy consolidation – the biggest firms getting bigger. At the bottom, a rapid expansion of small, agile boutiques. And in between, a mid-market that AlphaSense expects to shrink dramatically.

That word "dramatically" is doing real work, so it's worth understanding why the middle is the dangerous place to stand. A mid-sized firm is caught between two forces. It's too big to be cheap – it carries overhead, layers of staff, an office, a brand to maintain – so it can't compete on price with a lean boutique. And it's too small to be everywhere – it lacks the balance sheet, the global bench, and the breadth to win the enormous enterprise-wide transformation mandates the top tier fights over. So it ends up competing for work it's structurally wrong for, against opponents who are each better suited to that work on one axis or the other.

To see why this is happening rather than just that it is, you have to look at what changed at each end.

What's happening at the top

The big firms are getting bigger on purpose, and they're doing it by buying rather than building. AlphaSense puts the top five firms at roughly 40% of total industry market share – a striking concentration in a famously fragmented business. And the way they're growing tells you about the strategy. The trade press in 2026 reads like a shopping list: Consultancy.eu's news in a single week of June ran through a string of acquisitions, firms snapping up specialist capabilities in due diligence, AI, and particular sectors. The pattern, named in the February 2026 management consulting industry report, is consolidation around capability rather than geography.

Why buy instead of build? Because the market shifted under them. Clients increasingly want proven outcomes and demonstrated delivery, not a famous logo on a deck. When a buyer wants a specific, credible capability, the fastest way for a big firm to offer it is to acquire a firm that already has it. So the top consolidates, and with every acquisition the bar for "big enough to compete at scale" rises a little higher. The mid-market firm hoping to grow into that tier is chasing a line that keeps moving away from it.

What's happening at the bottom

The more interesting and more hopeful change is at the other end, and it's about economics. AI has rewritten the cost structure of a small advisory firm.

The traditional limit on a boutique was leverage – how much work a small senior team could do without hiring an army of junior analysts to handle the research, the data gathering, the modeling, the first-draft synthesis. That grunt work set a ceiling on what a small firm could take on. AI lifted the ceiling. The same research and analysis that used to require a roomful of analysts can increasingly be done by a lean team with the right tools. AlphaSense notes that for some firms, AI-enabled work already represents up to 30% of revenue – a sign of how much of the value chain these tools now touch.

The consequence is that a genuinely small firm – deep in one domain, senior on every engagement, fast because there's no bureaucracy to move through – now has leverage it simply didn't have three years ago. A three-person practice can credibly take on a scope that used to demand thirty people. It can deliver enterprise-grade work without enterprise-grade overhead, and price accordingly. The very same AI wave that lets the giants productize their services is what lets the smallest firms punch far above their weight.

The trap, and why it doesn't feel like one

So the market rewards being clearly one thing: large and consolidated, or small and sharp. It punishes being in between. And the genuinely dangerous part is that drifting into the middle almost never feels like a mistake while you're doing it. It feels like success.

Here's the usual path. A sharp two-person boutique does great work and gets busy. So it hires a few people. To keep them utilized, it takes on adjacent work slightly outside its core. To keep the pipeline full, it broadens the pitch so it appeals to more buyers. Every one of those steps is individually reasonable – responsible, even. But the sum is a firm that has slowly lost the things that made it a boutique – the depth, the seniority on every job, the speed – without gaining the things that make scale work, the balance sheet and bench and breadth. It became medium. And medium is the one place this market is actively emptying out.

What a genuine boutique should actually do

The strategic question for an independent advisor in 2026 isn't "how do we grow." It's "which end are we anchored to, and are we certain?" Because in a market pulling apart, the worst position is unanchored.

If your answer is the boutique end – and for most independent advisors it should be – then the moves follow from it. Stay narrow enough that your depth is genuinely undeniable, rather than broadening until you're a generalist nobody. Keep your senior people on the actual client work instead of layering in juniors to protect a margin, because the senior judgment is the product. Use AI to extend the reach of a small team – to take on bigger scopes while staying small – rather than as the justification for becoming a medium-sized firm. And resist the adjacent-scope creep that quietly converts a sharp practice into a blurry one, even when each individual piece of new work looks attractive.

Fieldway's own read on this is that boutiques aren't the underdogs in this split. They're one of the two structures the market is actively selecting for. The firms that lose aren't the small ones. They're the ones who, handed a market that finally rewards being clearly and confidently one thing, chose instead to be vaguely two.

The middle isn't a stage you pass through on the way up. In this market, it's where firms go to get squeezed. The good news, if you're small, is that small was never the disadvantage you might have feared. Right now, it's the edge.
