AT&T partners with Amazon to offer Leo satellite broadband for businesses

AT&T is partnering with Amazon to offer satellite internet to business customers, combining Amazon Leo's low-Earth-orbit satellite services with AT&T's fibre and 5G networks. AT&T becomes the first major US telecommunications provider to integrate Amazon Leo satellite services with existing networks. Amazon has been testing Leo with enterprise customers since November 2025 and plans to launch commercially this year. Leo has already secured contracts across several industries, including a partnership with Delta Air Lines. Amazon reportedly has 392 satellites in space, with 315 in the correct operational orbit. This remains far behind SpaceX's Starlink, which has 11,124 working satellites. The partnership targets enterprise and public sector customers seeking more reliable connectivity.

Tech giants' $1.1T AI spending spree raises cash-flow concerns as investment outpaces returns

Amazon, Meta, Microsoft, Alphabet and Oracle — collectively dubbed the "Hyper 5" — have spent $1.1 trillion on capital expenditures over the past five years to build AI infrastructure, according to S&P Global Market Intelligence. Analyst estimates project another $5.3 trillion in spending through 2030. The investment surge is putting pressure on free cash flow. Amazon's free cash flow fell to negative $7.6 billion over the 12 months ended 30 June, from positive $18.2 billion a year earlier. Meta's second-quarter free cash flow dropped 91% to $784 million. S&P Global warns the key risk is companies transitioning from cash to debt-funded investment before returns validate the spending. However, the tech giants remain highly profitable, distinguishing this cycle from the dot-com boom.
