(Reuters) -Flood insurance provider Neptune filed for a U.S. initial public offering on Wednesday, becoming the latest company to tap into renewed investor demand for new stocks.

As tariff worries fade and stock markets hover near record highs, the U.S. IPO market is seeing increased activity again, with investors favoring high-growth sectors and companies largely shielded from trade risks.

Analysts say the window through mid-October will be crucial, with several high-profile names lining up to gauge whether confidence in equities can withstand political and economic uncertainty.

Founded in 2018, Neptune provides flood insurance to homeowners and businesses. Flood insurance has become a pressing issue in the United States as climate change fuels more frequent and severe storms with millions vulnerable to damages and costs.

It is aiming to list on the New York Stock Exchange under the ticker symbol 'NP'.

Morgan Stanley, J.P. Morgan and BofA Securities are the lead underwriters of the offering.
