Introducing Castle A company, today, is an unintentional wrapper of macro events: an airline is an embedded oil trade, a solar developer is a tax-credit bet, and a data center is a wager on permits clearing before a moratorium lands. These exposures are intangible, lack historical data, and, therefore, remain unprotected on corporate balance sheets. On the other hand, there are players who actively seek this risk. As quantitative traders, we modeled these events, and we craved more avenues to express our opinions and to provide liquidity. Castle exists to bridge this gap. We leverage markets and models to cover the risks that insurers won’t, enabling businesses to focus solely on their execution. Read about one of our recent trades, in collaboration with our friends at Susquehanna and @Kalshi , as a CNBC exclusive linked below. We were quants, engineers, and hedge fund managers. Now, our Mission is to reprice one of the world’s oldest and largest markets. Find out more about Castle’s Mission below
