How Long Can the AI Money-Burning Game Continue? After Google's Plunge, Three Tech Giants Face Earnings Tests

Alphabet (GOOGL-US) reported its second-quarter earnings last week and significantly raised its capital expenditure outlook for 2026, triggering market skepticism about the return on artificial intelligence (AI) investments. The company's stock plunged 7% the next day, dragging down Amazon (AMZN-US), Meta (META-US), and Microsoft (MSFT-US). As these three tech giants release their earnings reports this week, investors will closely monitor AI infrastructure spending, cloud business growth, and free cash flow, testing market patience with tech companies' 'money-burning' data center expansions.

Google Loses Its Trust Premium: AI Spending Sparks Backlash

Alphabet has long been one of Wall Street’s most favored hyperscale cloud providers, primarily because it effectively converts massive capital expenditures into revenue. Over the past year, Google Cloud has grown faster than its competitors, and the Gemini model and related services have gradually gained traction in a market dominated by OpenAI and Anthropic, driving Alphabet’s stock price up approximately 70%.

However, investor sentiment toward AI spending is shifting. In previous quarters, tech giants raising capital expenditures was seen as proof of strong demand and growing backlog. But after Alphabet announced an increase in its 2026 capital expenditure forecast to accelerate AI data center construction, the market reacted negatively.

Alphabet’s stock dropped 7% the next day, reflecting investor concerns that rising AI infrastructure investments could deplete cash reserves, with uncertain timelines and scales of return. Long considered a 'cash printing machine,' Alphabet reported negative free cash flow for the first time in Q2 2024. Its long-term debt surged 111% to $98 billion in the first half of 2026.

Mark Mahaney, Managing Director of Internet Research at Evercore ISI, noted that Alphabet’s capital expenditure hike raises the likelihood that Amazon and Microsoft will take similar actions. The market will now scrutinize other tech giants more strictly, no longer accepting spending increases solely due to strong AI demand.

Microsoft and Amazon Face Rising Spending Pressures as AI Fatigue Spreads

Microsoft and Meta are set to report earnings after U.S. market close on Wednesday (29th), followed by Amazon on Thursday (30th). In April, Microsoft projected that its 2026 capital expenditures and finance leases would reach $190 billion, with about $25 billion attributed to component price hikes due to AI chip demand squeezing memory supply. Visible Alpha surveys show analysts currently estimate Microsoft’s annual spending at around $190.1 billion.

Cowen analyst Derrick Wood warned that if Microsoft further raises its capital expenditure, it could face selling pressure, referencing Alphabet’s stock reaction post-earnings. FactSet surveys even suggest Microsoft’s free cash flow could turn negative in Q4 2024—the first time since at least 2001.

Amazon forecasted in February that its 2026 capital expenditures would reach $200 billion, the highest among tech giants until Alphabet raised its upper forecast to $205 billion. After Alphabet’s earnings report, market estimates for Amazon’s capital spending increased by nearly $2 billion to $207.4 billion.

Analysts expect Amazon may further raise spending to expand AI, in-house chip development, and satellite network operations. The company’s long-term debt jumped 81% to $119 billion from end-2023 to March 2024, and its free cash flow turned negative in Q1. The market expects it to remain negative throughout the year.

Jake Dollarhide, CEO of Longbow Asset Management, pointed out that amid growing 'AI fatigue' and skepticism over soaring capital expenditures and tech giants’ debt-funded data center builds, Amazon may struggle to satisfy investors with this earnings report.

However, Wedbush argues that if increased spending supports AWS’s renewed growth and strengthens competitive advantages in Bedrock, Alexa, and logistics networks, the cost remains justified.

Cloud Demand Remains Strong: Market Now Focuses on Whether Spending Translates to Growth

Despite growing investor scrutiny over AI spending, cloud computing demand remains robust. Google Cloud’s Q2 revenue surged 82%, the fastest growth since at least 2020, up from 63% in the previous quarter. In 2020, Google Cloud was only 30% the size of AWS; by Q1 2026, it had reached nearly half.

AWS remains the global leader in cloud infrastructure, with Q1 revenue growth at 28% and Q2 projected to accelerate to nearly 32%. Microsoft Azure and other cloud services grew 40% in Q1, with Q2 expected at 39%.

Mahaney stated that cloud demand appears 'unstoppable,' but it will be difficult for other players to match Google Cloud’s Q2 growth pace. This puts investors in a dilemma: reducing spending risks losing customers due to insufficient compute capacity, while continued heavy investment could further erode cash flow and increase debt.

Meta is the only one of the four without a mature cloud services business. Analysts estimate its 2024 capital expenditure at around $138.9 billion, with the company previously indicating it could reach up to $145 billion. Meta continues to generate strong cash flow and is exploring selling compute capacity to third parties to monetize its massive AI infrastructure.

Tiffany Wade, portfolio manager at Columbia Threadneedle, said investors need patience with these tech stocks, as Alphabet, Amazon, and Microsoft remain potential long-term AI winners. She believes that given strong cloud demand, tech companies should buy additional compute from external suppliers rather than turn away customers due to capacity constraints.

The real test this earnings season is no longer whether AI demand exists, but whether Amazon, Meta, and Microsoft can prove that tens of billions in capital expenditures ultimately translate into cloud growth, profitability, and cash flow.
