The market Sompo writes
One page per line Sompo actually writes — property, casualty, cyber, construction, aviation, and the rest. The tape on each page is the whole industry, not the house file. Use Sompo for Sompo.

Storylines
- For Sompo this is a distribution event, not just a broker scoreboard. A combined Aon–NFP–USI middle-market machine will concentrate casualty, property, and specialty flow — and…
- Go to Monte Carlo with a one-page on Aspen integration, Service Insurance, construction appetite, and 1/1 casualty retro. The room will ask.
- Sompo’s specialty and Aspen cyber / management-liability capabilities need a clear answer when Gallagher Re shops these risks in the fall.
- The integration is no longer a slide. Monte Carlo this week is the first 1/1 cycle where counterparties will test whether Sompo Re + Aspen prices, authorizes, and services as one…
Risks
- Underinsurance is a claims event waiting. Sompo construction underwriters should be forcing mid-term value endorsements, not waiting for the next bound layer.
- Whitespace is not ‘casualty.’ It is auto, low-attach construction excess, and nuclear-verdict venues. Everything else is starting to see the property-capital overflow.
- If you need a one-line whitespace map: auto in, cyber out. Construction excess sits with auto. Public D&O sits with cyber.
Watch
- Property — Non-CAT rate still falling as capacity stacks
- Casualty — Excess attachment and capacity by class
- Construction — Builders risk vs excess casualty split
- Energy — Power / data-center energy-resilience placements

Risk products
Risk product
Property
Non-CAT commercial property is oversupplied in 2026 — Q1 premiums were down 5.5% and three-quarters of carriers added capacity. CAT, wildfire, convective storm, and older locations are a different market.

Risk product
Casualty
Casualty is fragmented, not uniformly hard. Primary general liability can be placed; excess, auto, and nuclear-verdict classes still price for social inflation. Capital released from property is leaking into casualty unevenly.
8 on the industry tape
Risk product
Cyber
Buyer-friendly and oversupplied. Q1 2026 rates were still down ~3.5% even as U.S. claims jumped nearly 40%. Capacity is chasing; the underwriting question is whether AI-accelerated claims reverse it before 1/1.
5 on the industry tape
Risk product
Professional lines
D&O is on an eighth consecutive quarter of rate decreases. Excess layers are abundant. Private / nonprofit is orderly. The gap is in rapidly scaling AI and data-center issuers whose disclosures are running ahead of controls.

Risk product
Surety
Infrastructure, energy transition, and data-center buildout are pulling surety capacity. Underwriting still screens contractor balance sheets harder than the builders-risk market does.

Risk product
Agriculture
Crop, livestock, and agribusiness remain a structured, subsidy-adjacent market. Climate volatility is rewriting MPCI results and private hail/named-peril pricing. This is a Sompo franchise through AgriSompo — the tape here is the whole ag market.

Reinsurance
Monte Carlo opens the 1/1 book. Property cat is more competitive than two years ago; casualty retro and specialty still screen. Sompo Re + Aspen is in the room as one franchise for the first time.

Industry verticals

Construction
Two markets. Non-CAT builders risk is negotiable (−5% to +10%). OCIP/CCIP primary is orderly. Excess casualty, auto, residential trades, and CAT-exposed projects are not. Tariffs have rewritten completed values 25–30%.
5 on the industry tape
Vertical
Energy
Upstream, midstream, downstream, and transition assets (solar, storage, hydrogen) still split on CAT, well-control, and liability. Power-for-AI is a new buyer sitting on old energy casualty forms.
0 on the industry tape
Vertical
Marine
Hull, cargo, liability, and war remain a specialist market. Red Sea / geopolitical war-risk pricing still gaps in and out. Inland marine overlaps construction and cargo.
2 on the industry tape
Vertical
Aviation
Airline hull/liability, airports, OEMs, and GA are separate buyers. Major-loss years still reprice the whole treaty; attritional GA and products liability have their own cycle.
0 on the industry tape
Vertical
Real estate
Habitational, office, industrial, and CRE portfolios are being underwritten as liability and CAT first, asset value second. Older buildings and habitational casualty are underserved; institutional industrial is competitive.
0 on the industry tape
Vertical
Healthcare
Medical professional, hospital, senior care, and allied health still live in a social-inflation market. Capacity is selective; the oversupply in D&O does not transfer here.
0 on the industry tape
Vertical
Life sciences
Clinical trial, products, and manufacturing liability for pharma, devices, and biologics. Capacity exists but terms still hinge on trial phase, territory, and recall.
0 on the industry tape
Vertical
Manufacturing
Products liability, recall, property, and supply-chain BI. Tariff-driven replacement values are the quiet underinsurance story, same as construction.
0 on the industry tape
Vertical
Mercantile
Retail, wholesale, and distribution — package, property, and premises liability. Shrinkage, habitational-adjacent locations, and auto fleets are the hard corners.
0 on the industry tape
Vertical
Technology
Tech E&O, cyber, media, and now AI liability. The cyber market is oversupplied; AI / model-risk and data-center adjacent tech is not a solved form.
1 on the industry tape
Vertical
Transportation
Commercial auto is one of the most underserved large lines in 2026 — rates still +8% to +15%, excess auto contracting, HNOA difficult. Trucking, fleets, and bus/shuttle do not get the cyber-style capacity flood.
2 on the industry tape
Vertical
Financial institutions
FI bond, D&O, professional, cyber, and lending-related PI. Banks and non-banks are being underwritten for cyber and professional first; D&O is the soft sleeve inside the tower.

Private equity clients
This is not the PE deals desk. It is insurance bought by sponsors and portcos — management liability, representations, portfolio programs, and deal-contingent cover. M&A volume still drives the demand.
