MGA Market 2026: Growth With Less Pricing Power

Renewal season, and a programme underwriter is having the best year of their career and the most uncomfortable one.

Submissions are up. The binder is growing. Carriers that would not return a call two years ago are now offering capacity on classes they had walked away from.

And the commission conversation has changed direction. So has the rate on almost everything in the book except liability.

That combination is the whole MGA story in 2026, and it is why two apparently contradictory pieces of news arrived within months of each other.

Twelve percent against five

Conning published its 2026 MGA study in July, and the headline number is a good one. US MGA premium reached about USD 128bn in 2025. The figure carriers actually filed, through statutory Note 19 disclosures, was USD 102.6bn.

That filed number grew 12% in a year. The property and casualty market as a whole grew about 5%.

So delegated underwriting took share, and took it at more than double the pace of the market it sits inside. Alan Dobbins, Conning's director of insurance research, framed it as structural rather than cyclical: the expansion “represents a meaningful evolution in how underwriting expertise, capital, technology, and distribution come together across the insurance value chain”.

Fronting is now a substantial part of how that works. Fronting carriers wrote USD 22.6bn of gross premium in 2025, roughly 20% of all MGA premium, standing between the underwriting talent and the balance sheet carrying the risk.

Then the outlook got cut

In February, AM Best revised its outlook on delegated underwriting authority enterprises from positive to stable. It did the same to US excess and surplus lines.

Not a downgrade. A statement that the exceptional period is over.

The reasoning is worth reading closely, because it is the mirror image of the growth story. Capacity has flooded into programme business and niche specialty. Rate momentum is easing. Carrier appetites are broadening again, which means the classes MGAs picked up when admitted carriers retreated are classes those carriers now want back.

AM Best also names the dependency that comes with the model. DUAEs lean heavily on reinsurance support, so when reinsurance capacity tightens the consequences arrive as compressed commission income and narrowing underwriting margins rather than as a headline event. The MGA does not own the balance sheet, which is the point of the structure and also the exposure.

Growth and diminishing pricing power are not in tension here. MGAs won share by being where capacity went when carriers pulled back, and that trade runs in reverse when carriers come back.

Where the lines actually moved

The averages hide the part that matters to anyone building a book, because the lines have gone in opposite directions.

Property is in freefall and casualty is the only line still hardening. In the US the split is wider still: property down 13%, casualty up 7%, in the same quarter and the same country.

Which sounds like an argument for pivoting into casualty, until you look at what casualty is doing to the people who write it.

Commercial lines overall ran at a 95.8 combined ratio in 2025, which is a decent year. Underneath that, commercial auto came in at 103.5, medical professional liability at 106, and other and products liability at 108. Casualty rate is rising because casualty is losing money, and a rate rise chasing a loss trend of twelve to fifteen percent is a smaller shortfall rather than a margin.

So the growing line is the unprofitable one, and the profitable line is the one whose price is collapsing. That is the actual strategic problem in this market, and no amount of distribution reach solves it.

More risks, less premium each

There is a second pattern in the 2026 data that gets less attention than rate and matters more to how an MGA is run.

Surplus lines premium grew 2.8% in the first half of 2026 while the number of item filings grew 16.9%, to 4.3 million. Inside that, E&S property premium fell 13.7% while property transaction volume rose 15.2%.

Read those two together.

The same books are handling substantially more risks and collecting less money for each one. An underwriter who quoted a hundred property submissions last year is quoting a hundred and fifteen this year, for less premium, and the commission on each is calculated off a smaller number. Every manual step in that process used to be an irritation. It is now the difference between a profitable programme and an unprofitable one, because the volume went up and the revenue per unit went down at the same time.

This is the mechanism behind AM Best's phrase about compressed commission income. It does not arrive as a negotiation. It arrives as arithmetic.

Britain shows where the capital went

The UK is the second largest MGA market and its numbers show the capital side of the same shift.

Milliman counts more than 300 MGAs underwriting over 10% of the £47bn UK general insurance market, with 233 members of the Managing General Agents' Association writing £13.2bn across the UK and Ireland between them, across more than 250 product lines. Membership has climbed steadily, from 187 in 2022 to 206 in 2023 to 233 in 2024.

Ownership tells you who thinks this model matters. Of the top 300, 58 are broker owned and 31 are insurer owned. Brokers are buying underwriting capability at roughly twice the rate carriers are buying distribution.

The most telling pair of numbers is about capacity rather than premium. Fronting companies supported USD 14bn of MGA premium in 2023, up 27% in a year. Lloyd's backed MGA premium over the same period grew 1%.

Capital did not just arrive. It changed route.

What survives a recalibration

Strip out the parts of this an MGA cannot influence and a short list remains. You cannot set the rate environment. You cannot make casualty profitable by writing more of it. You cannot conjure reinsurance capacity when it withdraws, and you cannot stop a carrier reclaiming a class it once abandoned.

What is left is the cost of running the book, the speed of getting a new product in front of a distribution partner, and the quality of the reporting your capacity provider sees.

All three are platform questions, which is the unglamorous reason they decide who comes out of a softening market intact. If premium per risk is falling and transaction count is rising, the cost of each policy touch is the margin, so policy administration and the automation between submission and issue stop being back-office concerns. If the profitable classes are moving, the ability to define a product and its rating as configuration a business user can change, with rates in effective-dated tables, is what decides whether you reach a niche before it closes. And capacity providers judge you on bordereaux that arrive clean and on time, which is a systems property rather than a diligence one.

The integration point matters as much for an MGA or coverholder, because in a competitive market distribution partners increasingly pick on how fast you can connect rather than on appetite alone.

The number to watch next

Twelve percent growth against a five percent market is a real achievement and it was earned in unusually favourable conditions. Those conditions have changed, and AM Best has said so in the only language a rating agency uses for it.

The interesting figure in next year's Conning study will not be total premium. It will be whether the filed number keeps outgrowing the market once carriers have finished reclaiming the classes they gave away, because that is the test of whether delegated underwriting is a structural shift or a very good decade.
