Hippo Holdings has expanded its partnership with specialty insurance platform Accelerant, a move that will significantly increase its presence in the U.S. specialty insurance market and accelerate its growth ambitions.

Under the enhanced agreement, effective 1 July 2026, Hippo will serve as a fronting carrier for more than $500 million in annual gross written premiums (GWP) across Accelerant’s U.S. portfolio during 2027. The full programme is scheduled to commence on 1 October 2026.

The expanded relationship has prompted Hippo to raise its growth outlook, with the company now expecting to achieve its $2 billion gross written premium target in 2027, one year ahead of its previous plan.

Expanding Specialty Market Presence

The partnership builds on the relationship established between Hippo and Accelerant in 2025 and reflects Hippo’s strategy of diversifying its underwriting portfolio while expanding into specialty insurance.

Through Accelerant’s Risk Exchange platform, Hippo will gain access to a broader specialty insurance portfolio, advanced risk selection capabilities, expanded distribution channels and enhanced reinsurance connectivity through Accelerant’s Risk Capital Partners.

The collaboration is designed to support disciplined underwriting while improving access to profitable specialty insurance opportunities.

Supporting Long-Term Growth

Hippo said the agreement strengthens its strategy of growing through selective partnerships that combine technology, data analytics and underwriting expertise.

Rick McCathron, President and Chief Executive Officer of Hippo Holdings, said the partnership represents a significant milestone in the company’s growth strategy.

“We are built to move decisively when the right opportunity presents itself, and this is one of those moments. Accelerant operates a data and technology platform that makes specialty insurance work better for the entire insurance value chain, and that same philosophy drives how we are growing Hippo. With this agreement in place, we expect to achieve our $2 billion gross written premium target in 2027, a full year ahead of plan.”

Strengthening the Accelerant Risk Exchange

Accelerant said the enhanced partnership will also benefit members of its Risk Exchange ecosystem by expanding fronting capacity and supporting the continued growth of managing general agents (MGAs).

Jeff Radke, Chairman and Chief Executive Officer of Accelerant, said the relationship has evolved significantly since it began last year.

“The partnership with Hippo strengthens the Accelerant Risk Exchange for our Members and the insureds. What began as a strong working relationship has grown into an exciting partnership and provides the best MGAs continued runway for profitable growth.”

The expanded agreement reflects the growing importance of data-driven partnerships and fronting arrangements within the specialty insurance market, where insurers are increasingly leveraging technology platforms and collaborative ecosystems to support underwriting growth while maintaining disciplined risk selection.
