The IPO Buzz: Quantinuum (QNT Proposed) On Tap in $4.7B-Plus Slate to Start June

Quantinuum (QNT Proposed) leads a $4.7 billion-plus lineup to get the IPO market off to a racing start for the month of June 2026. This week is viewed as a hectic warm-up for what’s expected next week – Elon Musk’s SpaceX (SPCX Proposed) is likely to get priced during the second week of June to raise about $75 billion, according to published reports. That timing is contingent upon SpaceX filing its terms and launching its deal later this week.

Anticipation is the name of the game.

Bankers expect to price eight deals, according to the IPO Calendar for the week of June 1, 2026. The calendar shows that seven IPOs are aiming to raise $4.69 billion combined – if all seven deals get priced at the mid-point of their respective ranges. One SPAC IPO – Aeon Acquisition I (AESPU Proposed) – is planning to raise $125 million; Chardan and D. Boral Capital are the joint lead book-running managers. Altogether, these eight deals are likely to raise $4.82 billion in combined proceeds.

A Quantum Computing Play

Honeywell-backed Quantinuum (QNT Proposed) is the name to note this week. Quantinuum’s $1 billion IPO is giving IPO players the chance to invest in quantum computing – both systems and software – to meet “the huge computational demands” of AI that “are making it challenging for classical computing to keep pace,” the prospectus said. The company is not profitable, according to the prospectus.

Quantinuum’s IPO is set to price on Wednesday night, June 3, 2026, to trade Thursday, June 4, on the NASDAQ.

J.P. Morgan and Morgan Stanley are the lead active book-running managers.

Applied Aerospace & Defense IPO

Applied Aerospace & Defense  (AADX Proposed) is on the IPO pros’ radar as well. The private equity-backed space and defense contractor is planning to raise $633.8 million with its IPO. The company designs, engineers and manufactures space and launch systems as well as defense aviation and airborne systems along with C5ISR and precision strike systems, the prospectus said.

The company was not profitable for the year that ended Dec. 31, 2025, according to the prospectus.

The Applied Aerospace & Defense IPO is expected to price on Tuesday night, June 2, 2026, to trade Wednesday, June 3, on the New York Stock Exchange.

Morgan Stanley and Jefferies are the joint lead book-runners.

INNIO Aims to Raise $1.91 Billion

INNIO Holding (INIO Proposed) is the biggest IPO of the week. INNIO expects to raise $1.91 billion – if it prices its 75 million shares at $25.50 – the mid-point of its $24.00-to-$27.00 price range. The principal shareholder, AI Alpine (Luxembourg), is offering all of the stock in the IPO. INNIO will not receive any of the proceeds from the IPO, the prospectus said. After the IPO, AI Alpine will hold stock representing about 90 percent of the voting power of INNIO’s outstanding stock, the prospectus said.

INNIO makes reciprocating natural gas engines and power generation systems. Its equipment segment sells engines under its Jenbacher and Waukesha brands, the prospectus said.  Its global clientele includes data centers, industrial companies and utilities. The company is profitable, according to the prospectus. INNIO’s services segment supplies parts and performs maintenance for its installed base of equipment under multi-year contracts, the prospectus said.

Bankers expect to price the INNIO Holding IPO on Wednesday night, June 3, 2026, to trade Thursday, June 4, on the NASDAQ.
