Added Jun 23, 2026
Excess and surplus lines are absorbing a growing share of the market as admitted carriers restrict appetite and standard markets struggle to price for elevated risk.
Analysis:
E&S growth is a massive structural shift. Startups building technology infrastructure for the E&S market — digital submissions, automated quoting, and data-driven underwriting for surplus lines — have a large and growing TAM. The E&S market has historically been technology-poor.
