"Companies creating an ‘AWS moment’ in the insurance industry are likely to focus on narrow segments of the value chain or functions (e.g. pricing, core platforms). They are unlikely to change the structure of the market in and of themselves but they dominate their area, sometimes creating monopolies or oligopolies. These companies are able to extract high ‘rents’ from incumbents who become reliant on their services.

Many would suggest that the catastrophe modelling market is one such oligopoly."
