3 Big Tech Earnings Reports to Watch as AI Bills Keep Growing

Big Tech Prepares for a Massive Earnings Week

It is shaping up to be a critical week for technology investors. Three of the world's biggest tech powerhouses—Microsoft, Alphabet, and Amazon—are gearing up to release their latest quarterly earnings reports. Investors are eagerly waiting to see whether massive investments in artificial intelligence (AI) are delivering real financial returns.

In their most recent quarterly reports, all three giants posted impressive expansion in their cloud computing divisions. Google Cloud surged by 82%, Microsoft Azure grew 42%, and Amazon Web Services (AWS) jumped 37%. However, building out AI infrastructure requires vast resources, and all three companies have been spending heavily on data centers, servers, and high-performance hardware.

The timing makes this week even more important for markets. Microsoft and Alphabet report their results on Wednesday afternoon, just hours after the Federal Reserve announces its latest interest rate decision at 2:00 p.m. Eastern Time (ET). Amazon follows shortly after with its quarterly report on Thursday.

Microsoft’s Azure Faces a High Bar for Growth

Microsoft (MSFT) gets things started after the market close on Wednesday, October 28, covering the first quarter of its 2027 fiscal year. According to estimates from ChartRow, Wall Street expects earnings per share (EPS) of $4.71, up from $4.13 in the same period last year. Consensus estimates from MarketBeat show revenue is projected to reach $90.63 billion, compared to $77.67 billion a year earlier.

Following its previous report in July, Microsoft stock jumped 15.0% after delivering an EPS of $4.74 to beat the $4.21 estimate. That pop ended a frustrating streak for investors, as Microsoft shares had fallen after each of the prior three quarterly reports despite beating earnings expectations every time.

In September, Microsoft shifted to a new two-segment organizational structure and began breaking out Azure as its own standalone revenue line. Under these restated figures, Azure generated $29.42 billion in revenue during the June quarter, reflecting a 42% growth rate. For the upcoming quarter, Microsoft guided for Azure growth between 44% and 45% in constant currency, alongside capital spending expected to top $50 billion.

Goldman Sachs analyst Gabriela Borges pointed out that Microsoft now controls more variables in its capital expenditure plans, giving the company greater strategic flexibility. She expects investors to focus closely on Azure's unit economics and return on invested capital. Microsoft shares closed at $524.51 on Friday, representing an 8.5% gain in 2026.

Alphabet’s AI Spending vs. Search Growth Concerns

Alphabet (GOOGL) reports later the same evening on Wednesday, holding its conference call at 4:30 p.m. ET. Wall Street estimates reported by ChartRow project EPS of $2.94, compared to $2.87 a year earlier. MarketBeat revenue consensus stands at $127.92 billion, up from $102.35 billion in the prior year.

Alphabet experienced a surprising market reaction following its July report. Even though EPS came in at $9.11—more than triple the $2.88 estimate—the stock fell 7.1%. Because that massive profit beat was tied to specific investment gains, analysts do not expect a repeat performance, keeping the current $2.94 estimate close to last year's baseline.

In the second quarter, Alphabet's revenue rose 24.2% to $119.8 billion, led by Google Cloud's 82% surge to $24.8 billion. However, capital expenditure hit $44.9 billion during the quarter, pushing free cash flow to negative $5.9 billion. In July, Alphabet also raised its full-year 2026 capex guidance to between $195 billion and $205 billion.

Goldman Sachs analyst Eric Sheridan noted that investor anxiety has focused primarily on core Search revenue growth and the absence of a formal consumer AI agent rollout. Nevertheless, Sheridan keeps Alphabet on Goldman's Buy list, highlighting its foundational AI models, Google Cloud momentum, and consumer app ecosystem as future catalysts. Alphabet shares closed at $320.21 on Friday, up 2.3% in 2026, representing the smallest gain among the three tech giants.

Amazon Web Services (AWS) Aims to Keep Accelerating

Amazon (AMZN) wraps up the big tech reports on Thursday, October 29, after market close. ChartRow estimates EPS at $2.01, up from $1.95 a year ago. Revenue consensus from MarketBeat sits at $202.16 billion, compared to $180.17 billion last year.

Amazon stock surged 15.3% after its July report, when EPS of $1.88 beat expectations of $1.83. AWS revenue jumped 37% to $42.2 billion in Q2, marking its fastest growth rate since late 2021. An analyst cited by Benzinga placed the consensus AWS growth rate for this quarter at 38%, with some forecasting potential expansion between 43% and 45%.

To support this momentum, Amazon raised its 2026 capital spending forecast in July to around $220 billion, up from its previous $200 billion plan. Second-quarter capex climbed to $54.2 billion from $32.1 billion a year earlier. CEO Andy Jassy emphasized that even at this investment level, Amazon still lacks sufficient capacity to meet all of this year's customer demand.

Heavy infrastructure outlays brought trailing 12-month free cash flow to negative $7.6 billion. To help fund its ongoing AI investments, Amazon issued $25 billion in bonds in July.

For the third quarter, Amazon guided total revenue between $197 billion and $202 billion, placing the $202.16 billion consensus slightly above the top end of that range. Additionally, Amazon's July GAAP EPS of $5.75 included $53.4 billion in pre-tax income, primarily from its investment stake in Anthropic, illustrating how headline profit can swing based on asset valuations. Amazon shares closed Friday at $248.00, up 7.4% in 2026.

The Big Picture: Massive Capex and Debt Issuance

The massive capital spending across these three tech giants carries broader implications for the global economy. Credit rating agency Moody's estimates that total tech sector capital expenditure could reach $785 billion in 2026 and approach nearly $1 trillion in 2027.

To fund these gigantic projects, hyperscale cloud providers are turning to the credit markets. Debt issuance among hyperscalers is running at approximately $175 billion this year, compared to a five-year annual average of just $30 billion.

Despite their massive reach, all three stocks have lagged behind the broader market benchmark this year. According to CNBC, the S&P 500 has gained over 11% in 2026, outperforming Microsoft (+8.5%), Amazon (+7.4%), and Alphabet (+2.3%). With cloud business growth ranging between 37% and 82%, this week's earnings reports will show whether robust operational performance can offset mounting AI bills.
