HawkEye 360 targets $2.4bn valuation in New York IPO

HawkEye 360, a leading signals intelligence company specialising in radio frequency satellite data, has launched its initial public offering roadshow, targeting to raise up to $416m through the sale of 16m shares priced at $24-$26, with an additional 2.4m shares available to underwriters. The company operates a constellation of more than 30 satellites, delivering intelligence to US and allied government customers. HawkEye 360 reported $117.7m of revenue in 2025, up 74% from 2024, with $2.7m in net income, $24.8m in EBITDA and a sharply reduced operating loss. IPO proceeds are expected to be used for debt reduction, acquisition-related payments and general corporate purposes. The listing comes amid increasing activity in the space sector, with rising investor interest in defence-focused satellite intelligence companies. [Read more]

SpaceX moves closer to blockbuster IPO with confidential US filing

SpaceX has confidentially filed for a US initial public offering, according to sources cited by Reuters on 1 April 2026, potentially setting up the largest IPO on record. The company is reportedly targeting a valuation of more than $1.75tn and could seek to raise over $50bn, eclipsing Saudi Aramco's 2019 listing. Much of the proposed valuation is attributed to Starlink, SpaceX's satellite communications business, which analysts describe as the company's main recurring revenue engine. A successful listing could act as a bellwether for large technology and space-related IPOs, lifting broader investor appetite for the sector. [Read more]
