$108.7 billion. That's what U.S. MGAs wrote in premium in 2025, up 17.8% in a year (AM Best).
The MGA boom isn't a pricing cycle. It's structural. But most analysis misses the real story: every force driving growth also raises the operational bar.

→ Non-exclusive carrier deals are now 57% of P&C direct premium. Carriers can shop for better-run partners, so your switching cost lives in operations, not your pitch deck.
→ The fastest-growing lines (cyber, flood, crop) are the hardest to administer.
→ Embedded distribution means more policies, smaller units, no room for manual back-office work.

The MGAs that scale won't win on alone. They'll win because they built policy administration and back-office capacity early, not once the strain hit the loss ratio.

MGA premiums hit $108.7B in 2025. But the boom is structural, and whether your program survives it comes down to operations, not just underwriting.

Facultative reinsurance is having a moment.

Every underwriting shop eventually meets a risk that doesn't fit. Too big for the net line. Outside the treaty. A class no standing agreement ever imagined.
Facultative is how you write it anyway: place exactly that risk, on your terms, without betting the balance sheet on one account.

And demand is climbing. Mordor Intelligence projects facultative placements to outpace the broader reinsurance market through 2031, driven by the large, strange, and specialty risks treaties leave out.

But here's what doesn't make the headlines: facultative is as much a systems challenge as an underwriting one. Every placement documented individually. Every fac cert tied to the right policy. Every bordereau reconciled. Get it wrong and the leakage shows up in your loss ratio.

Our latest breaks down what facultative reinsurance is, how it differs from treaty, and what it asks of the platform underneath it.

Facultative reinsurance lets carriers and MGAs cede individual high-value or unusual risks on custom terms. Learn how it works and why demand is rising.

$40B to $130B in a decade.

That's the U.S. & lines story, and it's now roughly 35 cents of every commercial P&C premium dollar.

We dug into a decade of AM Best, S&P GMI, and ALIRT data to answer three questions a headline can't:
Why did so much risk move to E&S? Property catastrophe losses and admitted-carrier retreat did the visible work. Social inflation and nuclear verdicts did the quieter, stickier work in casualty.

Who actually drove the growth? A cohort of 65 newer specialty carriers, many of them fronting operations tied to MGAs, now writes about a quarter of the market. Most of their surplus still comes from parent capital.

And what happens now that growth is cooling? Premium growth slowed to 9.7% through Q3 2025. AM Best moved its outlook from positive to stable. The next phase rewards discipline over expansion, and the winners will be the ones who can answer a capacity provider's questions with clean data and tight reporting.

Florida and California are the two big catastrophe markets everyone points to. They look like the same story. They aren't.

Florida's crisis was about legislation. Litigation reform reset the market, and carriers are coming back.

California's is about rate adequacy. Until Prop 103 loosens, the math doesn't work, no matter how much capacity you'd like to deploy.

Same headline, opposite playbooks. And for any carrier weighing where to expand next, that difference decides whether you're walking into a recovery or a market that hasn't found its floor yet.

A hallucinating doesn't fail visibly. It fails confidently.

No error message. No asterisk. Just a well-formed answer that happens to be wrong — and in P&C insurance, wrong looks a lot like a coverage dispute, a miscalculated premium, or a regulatory gap you can't explain to an examiner.

47% of enterprise AI users made at least one major business decision based on hallucinated content in 2024. That number doesn't get smaller when you add insurance-specific complexity to the mix.

We wrote a post for carriers and MGAs who want a clear-eyed look at what hallucinations actually are, how they surface in policy admin and underwriting workflows, and what governance architecture keeps them from becoming a liability.

Most P&C carriers and MGAs have heard both terms. Far fewer can explain the actual difference.

A system manages the full lifecycle of every policy you write. A calculates the premium. They work together, but they are built differently, owned by different teams, and break down in different ways when something goes wrong.

Confusing them is one of the most common and expensive mistakes carriers make when evaluating core technology. You can end up replacing a perfectly good PAS to solve a rating problem, or adding a standalone rating engine when the real issue is your policy workflow.

We broke down exactly how they differ, how they interact, and what it means for small and mid-size carriers deciding between embedded and standalone rating architectures.

A policy administration system and a rating engine are not the same thing. Confusing them leads to costly technology decisions for P&C carriers.

June 1 isn't just a date on the reinsurance calendar.

It's the moment that determines whether a Florida homeowners carrier can survive a major storm season.

We broke down what's actually driving the 6/1 renewal in 2025: FHCF retention shifts, ILS capacity hitting $114B, cat bond issuance up 39% year over year, and why small and mid-size carriers now represent 35% of the cat bond sponsor market.

What does it take to absorb 60,000 policies in a week?

That's what some Florida takeout carriers did in 2025 as dropped from 1.4 million policies to under 400,000 in two years. The carriers that thrived had more than capital. They had the operational infrastructure to back it up.

We broke down what actually separates the prepared from the unprepared: tech stack, staffing, and compliance readiness for takeout volume.
