PE mid-market: 'Capital concentration and what mid-market advisors must do differently'

Deal value up 44% — but deal count fell 6%.

The headline numbers look like a recovery. Look closer, and they tell a very different story.

Private equity deal value for buyout and growth transactions above $500 million reached $1.1 trillion in 2025 — a record, surpassing even the 2021 peak. Deals at that threshold increased 44% versus 2024, and buyout deals above $2.5 billion surged 72% to over $600 billion. If you read those numbers in isolation, you might conclude that the market has roared back to life.

But here is the question nobody in the mid-market seems willing to ask loudly enough: whose market has roared back?

While buyout deal count across all transaction sizes dropped 5%, the number of buyout deals over $500 million rose 20%. More money. Fewer deals. And almost all of that money sitting at the very top end of the market.

That is not a recovery. That is concentration. And for mid-market advisors, it is one of the most consequential structural shifts of the past decade — one that demands an entirely different operating playbook.

The anatomy of a two-speed market

Let us be precise about what the data is showing us.

Private equity firms announced or completed 18 megadeals valued at $5 billion or above in 2024 — more than double the prior-year total and the fourth-highest annual tally since 2000, according to S&P Global. That momentum accelerated further into 2025. Meanwhile, at the other end of the spectrum, smaller funds are being quietly squeezed out of the market entirely.

Megafunds — those raising $5 billion or more — accounted for 43.7% of all capital raised in 2024, while representing only 3.5% of fund count. Read that again. 3.5% of funds. 43.7% of capital. In 2020, funds smaller than $500 million raised $79 billion, or 17% of total fundraising. By 2025, that share had dropped to $60 billion and just 13% of the total.

This is not cyclical. This is structural. Capital is not waiting for conditions to normalise before flowing back down the size curve. It is consolidating — deliberately, systematically, and with LPs' full endorsement.

Fundraising has become increasingly concentrated, with LPs favouring large, established funds and avoiding smaller managers. High short-term bond yields and slower capital recycling have reinforced this flight to safety, pushing more money into mega-funds — the highest concentration in 15 years — while lower-tier GPs face fundraising cycles averaging 20 months.

20 months to close a fund. That is not a pipeline problem. That is an existential pressure on the mid-market ecosystem.

So where does that leave mid-market advisors?

Here is where the conversation needs to become uncomfortable.

For years, the mid-market advisory model was built on a relatively stable set of assumptions: a healthy volume of transactions in the £10m–£250m range, competitive but manageable processes, and a buyer universe that included regional PE houses, trade buyers, and family offices alongside the institutional names. That universe is contracting.

Between 2020 and 2025, the number of new PE firms declined approximately 18% per annum globally, while the number of first-time buyout fundraisers fell 15% per year. Fewer buyers. Fewer funds. More capital sitting with fewer managers who are chasing fewer, larger targets.

More sponsors are chasing fewer high-quality assets, while sovereign wealth funds and family offices — equipped with patient, low-leverage capital — continue to expand their presence.

What does that mean for the advisor sitting with a £30m EBITDA business, a motivated vendor, and a process timeline? It means the old assumptions about buyer depth, speed of decision-making, and deal certainty need to be fundamentally reassessed. It means the advisor who pitches the same process they ran in 2019 is not just out of date — they are actively misrepresenting the market to their client.

The valuation gap that won't close itself

The concentration of capital at the top does not just reduce buyer volume. It distorts the entire valuation environment in ways that disproportionately hurt mid-market sellers.

Deals valued between $2.5 billion and $10 billion continued to grow as a percentage of total value in both North America and Europe. When the most active part of the deal market is operating at multiples supported by mega-fund economics, leverage capacity, and platform-build logic, those comparable transactions start to create unrealistic benchmark expectations across the entire market.

Vendors read the headlines. They see 44% value growth. They do not see that the growth is concentrated in a segment that bears almost no resemblance to their own transaction profile. And so the valuation gap — between what sellers expect and what realistic buyers will pay in the mid-market — has not just persisted. In many sectors, it has widened.

The dry powder situation is certainly maintaining pressure on dealmakers. While the buyout industry's stockpile of unspent capital fell slightly from $1.3 trillion to $1.2 trillion, the value of aging dry powder — that held for four years or longer — ticked up to 24% of the total, from 20% in 2022. That suggests GPs are struggling to find first-rate, affordable targets.

There is capital in the market. There is appetite. But that capital has become highly discriminating, and the bar for what constitutes a "quality" asset has never been higher.

What must change — and what mid-market advisors must do differently

The question is not whether the mid-market advisory model needs to evolve. It clearly does. The more important question is: in which direction, and how fast?

First: stop selling process and start selling insight. The value of an advisor in a concentrated, buyer-thin market is no longer the ability to run a wide process. It is the ability to read the market with precision — to know which buyers are genuinely active, which mandates align with the asset, and which conversations are worth having before a formal process begins. Relationship intelligence, not process management, is the differentiator.

Second: become genuinely conversant in alternative capital structures. With exits sluggish, PE firms leaned heavily on alternative liquidity strategies in 2024–25, including minority stake sales, dividend recaps, secondaries, and NAV loans, driving $410 billion in liquidity events across 30% of buyout portfolio companies. These are not just GP tools. They are increasingly relevant frameworks for mid-market vendor situations — partial exits, growth capital injections, earn-outs with structured equity participation. Advisors who cannot articulate these options are not serving their clients fully.

Third: get ahead of the exit backlog conversation. Average holding periods for buyout deals reached 6.4 years in 2025, reflecting sponsors' preference to delay exits rather than exit at lower valuations. That backlog does not disappear — it creates a wave of assets that will eventually need to transact, and the advisors who have built relationships with the relevant sponsors now will be the ones mandated when those processes begin. Are you in those conversations today?

Fourth: sector specialisation is no longer optional. Outperformance will increasingly be driven by operational improvement, sector specialisation, and data-enabled transformation, not financial engineering. Firms that concentrate on a small number of areas where they can build true domain mastery will be best positioned to create outsized value and capture a disproportionate share of opportunities. The same logic applies to advisors. A generalist mid-market house competing for mandates against sector-focused boutiques — backed by teams with deep operational credibility — is playing a losing hand.

Fifth: rethink what "coverage" means. The family office and private wealth segment is becoming a material force in mid-market deal flow. Private wealth is particularly compelling: while individual investors hold roughly half of global capital, they represent just 16% of alternative assets today, leaving significant room for expansion. The advisors building systematic relationships in that segment — not just ad hoc conversations — will access a buyer pool that the traditional PE-focused process misses entirely.

The structural question nobody is asking

Here is the real issue underneath all of this.

The concentration of capital at the top of the market is not simply a market cycle phenomenon that will self-correct when rates fall or sentiment improves. It reflects a deliberate reallocation of LP conviction — away from the mid-market, toward larger, more liquid, more institutionally credible managers.

As consolidation among funds has intensified over the last decade, LPs are pledging more capital but tending to do so with fewer managers. Fewer managers means fewer buyers. Fewer buyers means thinner processes, longer transaction timelines, and more power asymmetry between buyer and seller in mid-market deals.

The advisors who thrive in this environment will not be the ones who wait for the market to return to the shape it held in 2019. They will be the ones who accept the structural reality, adapt their model accordingly, and start building the capabilities — in capital structuring, sector depth, alternative buyer relationships, and market intelligence — that the new environment demands.

Deal value is up 44%. Deal count is down. Capital is concentrating. The mid-market is not broken — but it is being fundamentally reshaped.

The only question worth answering is: are you reshaping with it?
