Industrial giant Honeywell International Inc. (HON.US) is set to spin off its aerospace business, while SpaceX's record-breaking IPO ignites imagination in the aerospace supply chain.

American industrial giant Honeywell International Inc. (HON.US) announced on Monday the new brand identity for its automation business and the upcoming spin-off aerospace business - Honeywell Technologies and Honeywell Aerospace. With Honeywell International Inc. set to officially spin off its aerospace business on June 29, 2026, the two companies will become independent and publicly traded on the U.S. stock market. Honeywell International Inc. currently has a market value of approximately $150.72 billion, and the automation business will operate under the name Honeywell Technologies and continue to publicly trade on the Nasdaq market under the stock code "HON." According to a statement, following the spin-off of the aerospace business, Honeywell Technologies will become a global technology leader in the transition from automation to end-to-end autonomy in the industrial sector, offering a comprehensive portfolio of products built on critical missions, outcome-based technologies, solutions, and software systems to drive customer productivity and performance growth. The company will be revalued against high-growth infrastructure assets in the future. At the same time, the aerospace business will trade under the name Honeywell Aerospace on Nasdaq under the code "HONA." The company will become one of the largest publicly-traded pure aerospace technology systems suppliers, with a leading position in technology and systems, and will continue to drive the future of the aerospace industry through growing electrification and autonomous flight systems. "Today marks another decisive moment in our transition to two independent and specialized companies," said Honeywell International Inc. Chairman and CEO Darius Adamczyk in a statement. With Honeywell International Inc. splitting into two entities, the publicly traded company with the code HON will continue to exist but will focus on automation technology, while the aerospace business will be separately listed with the code "HONA." The company has also arranged investor days for the aerospace and automation businesses, declaring that both companies post-divestiture will independently address the capital markets. Honeywell International Inc.'s latest spin-off is releasing an important market signal at a time when Elon Musk-founded space exploration and AI leader SpaceX is preparing for a record-breaking IPO with a targeted valuation of around $1.8 trillion. SpaceX recently announced plans to raise up to $75 billion, and if successful, this IPO would break global records. While SpaceX's recent Starship V3 test flight experienced booster return failures and was requested for investigation by the FAA, the test still achieved several key objectives, including simulating satellite deployment and controlled spacecraft splashdown. The market is currently grappling with two narratives: SpaceX's grand growth story challenging public market valuation ceilings with its reusable rocket business model, Starlink, AI applications, CECEP Solar Energy storage, and space orbit AI computing infrastructure; and mature industrial assets like Honeywell International Inc. striving to separate aerospace supply chains amidst the commercial aviation investment boom, capturing demand for avionics, autonomous flight, and commercial spaceflight overspill. The consolidation of Tesla, Inc., SpaceX, and xAI into a "trifecta" is shaping Musk's "super business empire," and may represent the ultimate fate of the three companies Musk has founded. With Musk's recent progress in areas such as space AI data centers, large-scale storage, AI, full self-driving (FSD), Robotaxi, and innovative Siasun Robot & Automation, the world's richest man seems to be weaving a financed, coherent "super vertical integration asset chain" that amplifies leverage in both the capital market and high-tech industries. As the wealthiest person in the world, Musk has achieved what others thought impossible in the past - building a commercially viable, high-frequency rocket launch business through SpaceX, bringing electric cars into the mainstream market through global electric vehicle leader Tesla, Inc., and providing internet connectivity infrastructure services from space through Starlink. However, some investors question whether Musk can truly establish his recent "epic" chip-making operation in Austin and realize his vision of AI, self-driving, Siasun Robot & Automation, space AI data centers, and human migration to Mars.
