Karn Saroya on House of Chimera: Can Reinsurance Become a Real-Time Capital Market?

• Karn Saroya, CEO of Re, joined an X Space with House of Chimera to break down what reinsurance is, why it matters, and why bringing risk transfer onchain creates value.
• Reinsurance is risk transfer, and it underwrites the insurance products that power everyday life, from mortgages to driving to small business operations.
• Re brings reinsurance onchain by turning proof of capital into a live, continuously verifiable system, improving transparency, trust, and liquidity.
• Re’s token model lets users choose between higher yield and higher liquidity, with Re’s own capital absorbing first losses, and DeFi integrations helping the product scale.

In a recent X space with House of Chimera, Karn Saroya, CEO of Re, unpacked what reinsurance is, and why moving the capital layer onchain is a better way to run the global risk market.

Insurance can feel like the opposite of exciting. It’s paperwork, premiums, and fine print, and it’s a system you hope you never need. But insurance underwrites modern life. Mortgages, car ownership, business operations, and basic economic activity depend on risk being priced and carried. Behind insurance sits an even more foundational layer most people rarely think about: reinsurance.

That is where Re comes in. Re is an onchain reinsurance company building infrastructure that makes proof of capital continuous, so risk markets can operate with transparency and lower friction.

The TL;DR: Reinsurance is Risk Transfer

Reinsurance is often described as risk transfer. As Karn explained, “reinsurance is insurance for insurance companies.” Insurance companies originate policies and collect premiums. To grow, diversify, or expand into new regions, insurers transfer part of that risk and part of that premium to reinsurers.

This risk transfer is what allows insurers to scale. Reinsurers operate as a capital backstop, absorbing risk so carriers can write more policies with stability.The value proposition here is that lowering the friction of risk transfer creates a more efficient and scalable insurance market.

Reinsurance is a Massive Market Few Notice

One of the striking moments of the X space was how quickly the conversation moved from skepticism about insurance to surprise at the size of the market. Reinsurance processes roughly $1 trillion in premiums per year, and the largest global reinsurers operate at a scale that is difficult to grasp without seeing the numbers.

Re is already operating at a meaningful scale today, while still early relative to the broader market. Karn shared that Re supports roughly “650,000 policyholders across the United States, backs 35 insurance companies, and supports around $350 million in business.”

Karn also emphasized how much room there is to grow in a market where the biggest players are enormous. “There are individual reinsurers that are larger than all of DeFi almost,” he said.

Onchain reinsurance is more than making DeFi more interesting, it is about connecting onchain capital rails to one of the largest, most durable markets in global finance.

Why the Old Model Struggles

Traditional reinsurance boils down to a promise to pay under certain conditions and proof that the capital is there when it matters. Karn described the product as “a promise that’s made to pay under certain conditions and proof that you can pay under those conditions.”

The challenge is that in traditional markets, proof does not behave like a live system. It is periodic and fragmented, with limited real-time visibility into capital and exposures

Re’s onchain thesis is that proof should be continuous. If capital and exposures can be verified in real-time, transparency increases trust, and trust increases liquidity. That liquidity can translate into a lower cost of capital, which becomes a durable competitive advantage.

Lowering friction in risk transfer creates value

Bringing reinsurance onchain is about improving the infrastructure that coordinates capital behind risk transfer. When friction drops, the system can move faster and allocate underwriting capacity more efficiently.

Lower friction can mean improved liquidity, lower cost of capital, and faster scaling for insurers that want to expand into new geographies or product lines. Over time, that infrastructure advantage compounds because capital can be verified, routed, and deployed efficiently.

How Re’s token model gives users choice

A key differentiator with Re is that the structure gives users a way to choose where they want to sit in the risk and liquidity tradeoff, rather than treating all depositors the same. Re uses a tranched capital structure, with Re’s own balance sheet positioned in front.

Karn explained that the transparency dashboard shows “65 million of our own assets in the risk-bearing layer.” The products express that structure through two tokens. reUSD is designed to be more liquid and more insulated from insurance losses. It uses overcollateralization and dedicated reserves to help support redemptions and maintain stability. reUSDe takes on more direct exposure to insurance risk, offering higher premium potential, but with lower liquidity.

Users can choose their position on the curve based on how much liquidity they want and how close to risk they are willing to sit.

Adverse Selection

A common skepticism about reinsurance is adverse selection. If insurers can offload risk, why would they not dump the worst risk and keep the best outcomes for themselves?

Karn says that reinsurance has long standing incentive structures designed to prevent exactly that. First, insurers retain skin in the game, which creates economic alignment. Second, insurers often take first-loss positioning so they feel deterioration before the reinsurer does. Third, contract structures can keep exposure within narrow bands that produce stable margin profiles.

He also noted that if a carrier tried to game the system, pricing responds, because every risk has a price and the market reprices when risk quality changes.

Why Insurance Can Improve in Downturns

One of the most surprising parts of the X space was the macro takeaway. Many people assume recessions automatically hurt insurance businesses, but Karn argued the opposite can be true.

In downturns, people often drive less and businesses see less activity, which can reduce both the frequency and severity of claims. Premiums, however, do not reprice immediately, so margins can improve.

That explains why Re distinguishes premium-backed yield; the return stream comes from large numbers of real-world premium payers and is less correlated with crypto market moves.

Composability as a Growth Engine

Onchain infrastructure is both a transparency upgrade, and a distribution engine. Once an asset exists as an onchain primitive, it can integrate across DeFi and become more usable, more liquid, and more composable.

Karn noted that reUSD can be used across venues such as Morpho and Pendle, and he referenced additional integrations like Silo. The practical implication is that distribution can scale through composability, because users can deploy reUSD within the broader DeFi stack rather than treating it as a standalone destination.

The more embedded and efficient capital access becomes, the harder it is for traditional market structures to replicate that efficiency offchain.

The Vision Ahead

The conversation closed with a clear view of where insurance markets are heading. Karn described a future where coverage becomes software-like, with AI systems coordinating risk decisions and capital in real-time.

In that world, capital proof cannot rely on periodic checks. It needs to function like a live system, verifiable and available programmatically. Re’s bet is that building this infrastructure now creates compounding advantages as markets shift toward faster, lower friction risk transfer.

Karn shared that Re’s 2026 goal is to add $400 million in new business and reach a $1 billion premium run-rate by 2027. He also noted early momentum, saying that as of February, Re had already written $147 million toward the 2026 target.

If Re continues to reduce friction in risk transfer through capital proof, transparent structures, and DeFi native distribution, onchain reinsurance may become one of the clearest examples of DeFi expanding beyond crypto-native markets into real-world financial infrastructure.
