Cloud revenue rose 103% at Alphabet (GOOGL) and 39% at Amazon (AMZN), showing AI is driving real growth, but the article argues free cash flow should be checked first because infrastructure spending consumes cash now while returns arrive years later. In the third quarter, Amazon reported $20.7 billion in net income, yet its $42.4 billion operating cash flow fell short of $75.9 billion in net equipment and property spending, leaving roughly negative $33.5 billion in free cash flow. Among the four AI spenders, Microsoft (MSFT) retained about $0.32 of each operating cash-flow dollar after capital spending, while Alphabet's spending exceeded operating cash for a second straight quarter, though these companywide figures do not isolate AI profitability. Amazon's quarterly interest expense rose from $538 million to $1.7 billion, and Microsoft's quarterly free cash flow fell about 27% from $25.7 billion a year earlier but stayed positive.

- Google, Microsoft, and Amazon have to justify the AI spending boom this week
Google, Microsoft and Amazon report quarterly earnings this week, and the key question is how well their AI spending pays off compared with expected returns. These companies, which lead a week of results accounting for more than a third of S&P 500 earnings, face the same scrutiny Meta faced. Bank of America said hyperscalers' 2027 capex estimates have already been revised up by nearly 90% year to date. Competition for capital is intensifying as AI labs prepare large IPOs and businesses scale back AI spending and use cheaper models, making it more important to justify AI costs.
- Alphabet vs Microsoft: Why Free Cash Flow Just Became the Only AI Scorecard That Matters
Alphabet fell 10.49% to $290.81 and Microsoft rose 2.78% to $545.78 in premarket trading on October 29, 2026, even though both reported results the same evening and are spending heavily on AI infrastructure. Alphabet's search revenue of $63.35 billion fell short of the $64.85 billion consensus, while Google Cloud revenue jumped 103% to $30.71 billion. Alphabet's capital expenditures of $51.36 billion exceeded its $42.29 billion operating cash flow, with the gap covered by $28.7 billion in senior notes and at-the-market stock sales. Microsoft, by contrast, posted fiscal first-quarter cloud revenue of $63.9 billion and free cash flow of almost $19 billion, while Alphabet's free cash flow was negative $9.1 billion. The article argues that free cash flow is becoming the key yardstick for comparing the two companies.

- Cracks are emerging in the AI spending boom
Investors are growing nervous about AI infrastructure spending, even as Alphabet, Amazon, Meta and Microsoft plan to spend more than $740 billion on capital expenditures this year. The Nasdaq fell 2.9% on Friday, with chip stocks hit hard and Qualcomm down 11%. Alphabet plunged 12% on Thursday, wiping out $500 billion in market value, and reported negative free cash flow of $9.1 billion in the third quarter while expecting to spend up to $205 billion this year, as its Search advertising growth slowed to 12% amid the rollout of AI Mode. Amazon posted negative free cash flow of $42.4 billion over the past 12 months despite 39% AWS growth, and Meta reported negative free cash flow of $2.1 billion in the third quarter even as ad revenue rose 26%. Negative cash flow, mounting debt and doubts about whether these investments will pay off are weighing on market sentiment.
- Big Tech Earnings Face a $600 Billion Question: Is AI Spending Paying Off?
U.S. stocks rose Monday, helped by enthusiasm for AI, but this week's earnings from Alphabet, Microsoft and Amazon will test whether that optimism holds under closer scrutiny of the technology's enormous costs. The three companies have nearly $1.7 trillion in combined backlog and plan to spend as much as $600 billion this year. Investors now want to know whether that spending is paying off.

- Amazon Soars 5% as Phillip Securities Upgrades It to Buy After Earnings Sell-Off
Amazon (AMZN) shares rose 5% after Phillip Securities upgraded the stock to Buy with a 330 USD price target, following a Friday sell-off over AI spending that outpaced cash flow. Phillip analyst Helena Wang pointed to demand visibility: AWS revenue grew 39% to 46.0 billion USD last quarter, backlog reached 578 billion USD, and CEO Andy Jassy projected AWS growth above 40% in both 2027 and 2028. Against this, capital spending has nearly tripled since late 2024 to 77.3 billion USD in the September quarter, leaving trailing 12-month free cash flow at a 42.4 billion USD outflow. Alphabet and Meta face similar cash shortfalls, while Nvidia stands to benefit from the spending. Amazon's forward P/E fell to 24x, its lowest in five years and less than half its five-year average of 49x.

- Amazon is on a course to spend half a trillion dollars in a single year: JPMorgan
JPMorgan tech analyst Doug Anmuth projects Amazon's capital expenditure will reach 395 billion USD in 2027, up 77% year over year, and 476 billion USD in 2028, up 20%, as he expects capex growth not to slow next year. He argues management's strong visibility into demand gives it confidence to underwrite growth above 40% over the next two years and to invest even more aggressively in AI infrastructure. Amazon itself estimated 2026 capex at 220 billion USD, while CEO Andy Jassy said 2027 spending would be 'meaningfully more' without giving a figure. Trailing 12-month free cash flow turned to a 42.4 billion USD outflow, driven by a 94.8 billion USD year-over-year increase in property and equipment purchases, mainly for AI. Shares fell over 1% on Friday before rebounding Monday, lifting year-to-date gains to 9% versus 11% for the S&P 500.
- Tempus AI Revenue Up 23%; Gains Cut Net Loss: Rapid Earnings Reaction
Tempus AI (TEM) reported third-quarter revenue up 23% to $411.5 million and raised its 2026 revenue outlook; shares rose about 3.9% in pre-market trading. The net loss narrowed to $14.9 million from $80.0 million, mainly due to $42.8 million in unrealized gains on marketable securities, while the operating loss barely changed at $56.9 million versus $61.0 million. Data and Applications revenue rose 33% to $108.1 million, with a gross margin above 71%, which lifts overall margins. Adjusted EBITDA reached $25.6 million versus $1.5 million a year earlier, though it excludes about $48 million in stock-based pay. The adjusted EBITDA outlook held at about $65 million, implying about $34 million in the fourth quarter, and the article flags Hereditary testing revenue, up just 3%, as a point to watch.
- Bitmine Buys More Ethereum as Tom Lee Calls the Binance Hack Bullish
Bitmine Immersion Technologies bought 8,573 more ETH in its latest weekly purchase, lifting total holdings to 6,060,506 ETH, worth about $13.7 billion, or 4.9% of Ethereum's 122.2 million token supply. The company said it is 99% of the way to its goal of owning 5% of the network. Chairman Tom Lee said the record $6.4 billion Binance hack, which the FBI attributed to North Korea, showed crypto's resilience, as ETH fell only 4%, compared with an 8% drop on the day of the $1.5 billion Bybit hack in February 2025. Lee cited six reasons, including Binance's ability to cover all customer losses and the FBI naming North Korea within two days. As of Nov. 1, total holdings, including cash, other tokens and investments, reached $14.5 billion, and about 86% of its ETH is staked through its MAVAN platform, with projected annual staking revenue of about $358 million.
