Sept 19 (Reuters) - Crypto custody startup BitGo's

revenue nearly quadrupled in the first half of 2025, its filing

for a U.S. initial public offering showed on Friday, following a

string of stellar crypto debuts as investors flock to new

listings.

U.S. IPOs are set to have one of the busiest issues since

2021 this fall, with crypto firms anchoring a market that was

scuttled by tariff uncertainty in April.

Blowout day one receptions to stablecoin giant Circle

, crypto exchange Bullish and blockchain lender

Figure have reinforced investor appetite for the

digital assets sector, which has made significant headway

towards mainstream acceptance on marquee regulatory wins.

As Washington takes an increasingly welcoming stance on a

sector that once was on the fringes of finance, ETF flows and

institutional adoption have also upticked.

"Investors are increasingly viewing digital assets as an

asset class in their own right, rather than purely speculative

instruments," said Josef Schuster, CEO of IPO research firm

IPOX.

Founded in 2013, BitGo is one of the largest crypto custody

firms in the United States. It stores and protects digital

assets for clients, a role that has gained importance as

institutional interest in crypto grows.

It secured a valuation of $1.75 billion in a 2023 funding

round.

BitGo reported a profit of $12.6 million on revenue of $4.19

billion for the six months ended June 30, compared with a profit

of $30.9 million on revenue of $1.12 billion a year earlier.

BitGo intends to list on the New York Stock Exchange under

the symbol "BTGO".

Goldman Sachs and Citigroup are the lead underwriters for

the offering.
