Bamboo Insurance Services, Inc. filed a Form S-1 registration statement dated Aug. 28, 2026, with the SEC for a proposed initial public offering targeting $100 million. The company has applied to list Class A common stock on the New York Stock Exchange under the ticker BMB, although the number of shares and price range have not been determined. J.P. Morgan and Morgan Stanley are joint lead bookrunning managers, joined by Deutsche Bank Securities, Evercore ISI and Wells Fargo Securities as active bookrunners. Bamboo, founded in 2018 by John Chu, operates as a technology-enabled managing general underwriter that partners with insurance carriers rather than taking underwriting risk directly. It focuses on homeowners coverage in wildfire-prone California and has expanded into Texas across homeowners, condo, landlord and renters insurance. Revenue reached $173 million in the first half of 2026, up from $124 million a year earlier, while profit fell to $13.8 million from $23.7 million. Managed premiums are approaching $900 million. Majority owner CVC Capital Partners acquired control in a 2025 transaction valuing Bamboo at $1.75 billion, while White Mountains Insurance retains a minority stake. The shares are to be sold by certain stockholders, so Bamboo itself would not receive IPO proceeds. The registration statement is not yet effective, and the offering terms remain subject to change.
