Megaport (ASX:MP1) closed 7.80% higher on 29 September 2026 as investors assessed new AI-infrastructure contracts and an upgraded FY27 Revenue outlook. The network-as-a-service provider’s exposure to cloud, data-centre and AI connectivity remained central to the market response.

Megaport is a network-as-a-service provider that lets businesses connect to cloud platforms, data centres and each other on Demand through software rather than through the slow, fixed process of provisioning physical circuits. Its network spans data centres around the world, and its customers use it to spin connectivity up and down flexibly as their needs change. As the plumbing that links enterprises to major cloud and infrastructure providers, Megaport sits squarely in the path of the surge in data-centre and artificial-intelligence build-out that has reshaped technology investment, which makes contract news tied to AI infrastructure especially significant for the stock.

The catalyst on Tuesday was exactly that. Megaport told the market it had secured three AI-infrastructure contracts worth around US$978.6 million, a headline figure large enough to reframe the company’s growth trajectory in investors’ eyes. On the back of those wins, Megaport lifted its FY27 revenue guidance to a range of A$720 million to A$810 million, up from the previous A$620 million to A$730 million. An upgrade of that magnitude, backed by named contract wins rather than aspiration, is precisely the kind of update that prompts a sharp re-rating, and it explains why the shares responded so strongly.

The timing helped. The dominant global theme heading into the session was a surge in bond yields, with the US 10-year Treasury Yield pushing to roughly 5.24%, a fresh high since 2007, as markets lifted the odds of an October Federal Reserve rate hike toward 70%. Higher long-end yields are typically unkind to growth stocks, whose value rests heavily on cash flows well into the future. Yet the session also featured a bounce in select tech and growth names, one of the identifiable themes of the day, and Megaport was well placed to ride that bounce given it arrived with concrete, AI-linked contract news rather than merely benefiting from a sentiment swing.

That combination is worth underlining. On a day when the yield story was crushing rate-sensitive sectors such as REITs and gold miners, and when the overall market was struggling for direction beneath a thin headline gain, Megaport offered two things at once: exposure to the AI-infrastructure Investment wave that continues to dominate technology spending, and a tangible upgrade to its own revenue outlook. Investors did not have to take the growth story on faith, because the guidance lift was anchored to specific contracts.

Megaport’s move also sat comfortably within the session’s broader pattern, in which the biggest individual gains were driven by company-specific Earnings and guidance news rather than the macro backdrop. While the yield surge dictated the fate of bond-proxy and property names, the standout risers were those with their own catalysts. Megaport had one of the most compelling of the day: nearly a billion US dollars of AI-infrastructure contracts and a materially higher revenue outlook to match. For a company whose entire proposition is connecting businesses to the infrastructure underpinning the AI era, Tuesday delivered a validation the market was quick to reward.
