What RSKX is

An exchange where catastrophe exposure is a tradable contract.

Today, when an insurance carrier needs to offload exposure to a wildfire season, a hurricane corridor, or a flood-prone county, the options are slow, bilateral, and opaque. Reinsurance treaties are negotiated months in advance behind closed doors. Catastrophe bonds take a year and millions in legal fees to bring to market.

There is no real-time, transparent venue where a carrier can simply buy down its tail the way an airline buys fuel hedges or a bank hedges rate risk.

We're building that venue. On RSKX, catastrophe exposure becomes a standardized, tradable contract — listed, priced in the open, and matched between the desks that need to shed risk and the desks that want to take it on.

HOW IT WORKS

A standardized contract. A live order book. Automatic settlement.

Every contract is written against a defined event in a defined geography — a named hurricane making landfall above a wind threshold, a wildfire crossing an acreage threshold inside a hex, a flood event exceeding a stage trigger. Listed publicly. Matched continuously. Settled when the event data is in.

01

List the contract

Each contract is keyed to an H3 resolution-9 hex (≈ 400 m across) and a defined event threshold. Specifications are public. Anyone can quote on either side of the book.

HURRICANE · R03·C07
02

Match in the open

Real-time bid/ask, transparent depth, executed against a public order book. Makers post liquidity, takers fill it. Same rules every desk that's ever traded electronically already knows.

BID 56.2¢ · ASK 56.8¢
03

Settle on event data

When the qualifying event data lands from NOAA, USGS, NIFC, or NWS, the contract resolves automatically. Cash-settled in USD. 48h dispute window. No claims process, no adjudication.

WHO TRADES ON RSKX

Two sides of one book.

On one side, institutional desks laying off correlated CAT exposure. On the other, allocators and traders taking on catastrophe as an uncorrelated asset class — without the lock-up and legal cost of a cat bond.

HEDGERS

Anyone whose balance sheet owns the tail.

Most of the volume on RSKX is institutional. Carriers, MGAs, reinsurers, state plans — desks that hold concentrated, correlated CAT exposure and need a faster, cheaper way to lay it off.

Carriers & MGAs Offload CAT aggregate from a specific footprint to keep writing new business in it.
Reinsurers Hedge retroceded exposure precisely, at the hex level, without rolling another treaty.
State plans Citizens FL, California FAIR Plan, and other insurers of last resort buy down tail capacity.
Munis & utilities Hedge weather-driven load and infrastructure exposure (ERCOT freezes, wildfire shutoffs).
Corporate risk Energy desks, REITs, agribusiness — anyone whose P&L moves with a named weather event.
Homeowners Smaller volume, real use — buy a contract on your hex when your policy won't price the deductible.
SPECULATORS

Trade the weather.

On the other side of the book, allocators and traders who want exposure to a fat-tailed, weather-driven asset class that doesn't correlate with the rest of their portfolio.

ILS funds Replace a single ILW or cat-bond position with a live order book of granular exposures.
Hedge funds Trade weather as an uncorrelated alpha sleeve, sized at the contract not the treaty.
Family offices Take direct exposure to catastrophe risk without locking up capital in a multi-year SPV.
Quant desks Build climate, wind, and precipitation signals straight into a tradeable contract.
Market makers Post two-sided liquidity, capture spread, earn rebate. Standard exchange role.
Retail (limited) Capped position sizes. Available where local regulation permits.
