Sept 29 (Reuters) -

Electric aircraft maker Beta Technologies filed for an

initial public offering in the United States on Monday, the

latest company to join the rush to tap a record-breaking bull

run in the equity market.

Easing trade tensions, robust stock markets and pent-up

investor demand have combined to create one of the busiest

windows for listings in years, with technology, aerospace and

green energy firms leading the charge.

Beta Technologies designs, manufactures and sells

high-performance electric aircraft, advanced electric propulsion

systems, charging systems and components.

Electric aviation remains a niche segment of the

transportation industry, with only a handful of companies

developing and testing commercial aircraft.

The company said, citing internal estimates, that operating

costs for its aircraft are 42% lower than conventional planes,

thanks to a simplified design.

"Our aircraft's design eliminates the need for complex

components such as gear boxes, in-flight liquid cooling systems,

and thrust vectoring mechanisms," it added in the IPO

prospectus.

Beta Technologies said its ALIA CTOL electric aircraft

has completed thousands of flights, covering nearly 83,000

nautical miles, including operations in North America and

Europe.

The company's aircraft has also been used by the U.S.

military in training missions and flown by the Federal Aviation

Administration (FAA).

The broader electric vehicle and technology industries

have been in the spotlight for years, drawing investment and

fueling growth across the automotive and clean-tech sectors.

Interest, however, has been uneven, with some segments

and regions growing rapidly while others face adoption and

infrastructure challenges.

Beta Technologies, backed by tech giant Amazon ( AMZN ),

did not disclose the size or terms of its offering.

The company is aiming to trade on the New York Stock

Exchange under the symbol "BETA."

Morgan Stanley and Goldman Sachs are the lead underwriters

of the offering.
