Global  stock markets are approaching one of the most important financial evenings of October 2026.

The U.S. Federal Reserve is preparing to announce its latest interest-rate decision, while Microsoft and Alphabet, Google's parent company, are scheduled to publish quarterly earnings after Wall Street closes.

These developments arrive as investors reassess the sustainability of the artificial intelligence investment boom, elevated interest rates and the relationship between technology spending and corporate profitability.

The timing is particularly important.

On October 27, the Nasdaq Composite climbed 1.18%, while the S&P 500 gained 0.60%, supported by renewed enthusiasm for artificial intelligence and semiconductor companies.

However, Wednesday's early U.S. trading was more cautious.

Investors were balancing stronger semiconductor demand against concerns about large technology companies' capital expenditure and the possibility that the Federal Reserve could maintain restrictive monetary policy.

The central question is straightforward:

Can strong AI-related earnings support technology valuations if the Federal Reserve keeps interest rates elevated?

The answer may depend less on whether Microsoft's and Google's revenue exceeds expectations and more on whether their enormous AI infrastructure investments are generating sustainable returns.

For Indian investors, the outcome could influence Nifty IT, foreign portfolio flows, the rupee and the valuation of technology companies.

1. Why October 28 Is Important for Global Markets

Two major events are scheduled within hours of one another.

First, the Federal Open Market Committee will announce its monetary-policy decision.

Second, Microsoft and Alphabet will publish results covering the September 2026 quarter.

These events influence financial markets through different mechanisms.

The Federal Reserve affects the cost of capital, interest-rate expectations and global financial conditions.

Big Tech earnings influence expectations for corporate profits, AI demand and future technology investment.

When both developments occur on the same evening, investors must reassess the price they are willing to pay for future earnings.

Tonight's Key Events

All times are scheduled and shown in Indian Standard Time where relevant. Microsoft and Alphabet are expected to publish their earnings releases after the U.S. market closes.

This sequence creates the possibility of two separate market reactions.

Stocks may respond initially to the Federal Reserve's language and later react to the earnings and guidance released by technology companies.

The result could be a volatile overnight session for Nasdaq futures and global technology shares.

2. What Is the Federal Reserve Expected to Do?

The Federal Reserve raised its benchmark policy-rate range by 25 basis points in September 2026.

That brought the federal funds target range to 3.75%–4.00%.

The September decision reflected the Fed's concerns about persistent inflation, even as economic activity and employment remained relatively resilient.

For October 28, market expectations largely favour leaving rates unchanged.

However, maintaining the same interest rate does not necessarily mean that monetary policy will become less restrictive.

Investors will pay close attention to the Fed's assessment of inflation, economic growth and the possibility of further interest-rate increases.

The most important question is whether policymakers believe existing rates are sufficient to bring inflation toward their 2% objective.

Three Possible Federal Reserve Outcomes

These are hypothetical scenarios, not predictions.

Even if rates remain unchanged, the Fed Chair's comments could significantly influence Treasury yields and the dollar.

A hawkish message would suggest that interest rates may need to remain elevated or rise further.

A softer message could reduce expectations for additional tightening.

Both outcomes would influence how investors value technology companies whose anticipated profits extend far into the future.

3. Why Interest Rates Matter So Much for AI Stocks

Technology companies are particularly sensitive to changes in  financial conditions because a large portion of their valuations often depends on expectations for future earnings.

When interest rates rise, investors generally apply higher discount rates to those future cash flows.

Other things being equal, this reduces their present value.

The effect can be especially significant for high-growth businesses whose expected profits lie several years ahead.

But today's AI market presents an additional challenge.

Large technology companies are committing substantial capital to data centres, processors, networking equipment and energy infrastructure.

These investments must eventually generate enough revenue and cash flow to justify their cost.

Higher financing expenses can make projects less attractive, particularly when investments require significant borrowing or take years to produce returns.

Therefore, AI investors are now evaluating two issues simultaneously.

First: Will the Federal Reserve provide an environment supportive of technology valuations?

Second: Can AI companies convert rising infrastructure investment into sustained financial returns?

This combination makes tonight's policy announcement and technology earnings unusually interconnected.

4. Microsoft Earnings: Can Azure Growth Justify AI Spending?

Microsoft is one of the most important companies in the global AI investment ecosystem.

Its Azure cloud platform provides computing infrastructure used by enterprises, software developers and AI applications.

Microsoft is also investing in AI-enabled software, enterprise applications, data centres and cloud services.

For the September quarter, analysts surveyed by Visible Alpha expected Azure revenue growth of approximately 47.7% year-on-year, accelerating from 42% in the previous quarter.

Reuters also reported expectations for Microsoft's total revenue to increase around 16.7% to $90.66 billion.

These are analyst forecasts, not announced results.

Microsoft's earnings report is particularly significant because the company is introducing a revised financial reporting structure.

Its updated reporting is expected to provide investors with absolute quarterly Azure revenue figures, rather than relying primarily on percentage-growth disclosures.

That additional transparency could make it easier to assess the relationship between AI-related capital spending and cloud revenue.

What Investors Should Watch in Microsoft Earnings

A strong Azure report may provide reassurance that AI infrastructure spending is supported by real customer demand.

However, strong cloud growth alone may not be sufficient if capital expenditure continues increasing much faster than operating cash flow.

The crucial question is not simply how fast Azure is growing, but how efficiently Microsoft can turn that growth into profits and cash.

5. Alphabet Earnings: Google Cloud Growth Versus Search Disruption

Alphabet faces a different combination of opportunities and risks.

Google Cloud has become a major growth engine, benefiting from enterprise cloud adoption and demand for AI computing infrastructure.

According to LSEG estimates cited by Reuters on October 27, Google Cloud revenue was expected to increase approximately 95.1% year-on-year to $29.57 billion during the September quarter.

Meanwhile, Alphabet's total revenue was expected to increase approximately 25.2% to $128.18 billion.

These forecasts highlight the extraordinary growth anticipated in cloud services.

But Alphabet also faces questions about its traditional Google Search business.

AI-powered assistants, conversational search engines and autonomous agents are changing how users interact with online information.

Investors are watching whether these technologies create additional opportunities for Google or gradually weaken its established search-advertising business.

Reuters reported that Google Search revenue growth was expected to moderate to approximately 14.7%, compared with 16.8% in the preceding quarter.

The results will therefore be important for two reasons.

Google Cloud needs to demonstrate that AI-related demand remains strong.

At the same time, Alphabet must reassure investors that changes in search behaviour are not materially undermining its core advertising economics.

What Investors Should Watch in Alphabet Earnings

The most important development may be management's commentary on the economics of AI.

A company can demonstrate rapid AI adoption while still facing uncertainty about how much profit each additional user or workload will generate.

Investors will want evidence that usage growth can translate into sustainable margins.

6. The Bigger AI Question: Is Big Tech Spending Too Much?

The scale of AI investment has become one of Wall Street's most important debates.

According to Reuters, Microsoft, Alphabet and Amazon collectively have nearly $1.7 trillion in business backlog and could spend as much as $600 billion during 2026.

These figures illustrate both the extraordinary commercial opportunity and the significant  financial commitments involved.

The investment includes data-centre construction, processors, cloud infrastructure, networking equipment and supporting systems.

Such expenditure can create substantial demand for semiconductor manufacturers and industrial suppliers.

However, infrastructure investment does not generate guaranteed shareholder returns.

A data centre must attract customers, operate efficiently and produce sufficient cash flow to justify the capital employed.

The distinction between revenue growth and return on invested capital is becoming increasingly important.

Investors are no longer asking only whether technology companies can build more AI capacity.

They are asking whether the additional capacity will produce attractive financial returns.

This may mark a new phase in the AI investment cycle.

During the earlier phase, announcements of large AI spending programmes often generated enthusiasm.

Now, investors are increasingly evaluating spending discipline, financing costs and free-cash-flow generation.

7. Strong Semiconductor Demand Adds Another Dimension

The latest developments in Asia demonstrate that demand for AI hardware remains substantial.

On October 28, South Korean memory-chip manufacturer SK Hynix reported a more than sevenfold increase in quarterly profit.

The results supported semiconductor shares in Asia and contributed to gains in selected American chip  stocks.

During early U.S. trading, Micron Technology advanced approximately 4.8%, while the Philadelphia Semiconductor Index gained around 0.9%.

The contrast is noteworthy.

Semiconductor manufacturers are reporting strong demand for critical AI components.

At the same time, investors are questioning whether the companies purchasing enormous quantities of this equipment will generate sufficient returns.

These are not necessarily contradictory signals.

Hardware manufacturers can experience strong demand during an investment expansion even when the ultimate profitability of the companies financing that expansion remains uncertain.

The key question is whether AI infrastructure spending can remain financially sustainable over several years.

8. What Could Tonight's Events Mean for Nasdaq and Global Stocks?

The combined market impact will depend on the Fed's guidance and technology companies' earnings.

Four broad scenarios are possible.

Scenario 1: Softer Fed + Strong Technology Earnings

The Federal Reserve signals reduced concern about inflation, while Microsoft and Alphabet report strong cloud growth and reassuring cash flow.

This would create a relatively supportive combination for technology valuations.

Investors could become more confident about both financial conditions and AI-related earnings growth.

Scenario 2: Hawkish Fed + Strong Technology Earnings

The Fed signals that interest rates may remain elevated or rise further, while technology companies deliver strong results.

In this scenario, earnings optimism could be offset by higher discount rates and financing costs.

Large technology stocks might respond differently depending on valuation and balance-sheet strength.

Scenario 3: Softer Fed + Disappointing Technology Guidance

The Fed adopts a less restrictive tone, but Microsoft and Alphabet indicate weaker cloud demand or rising investment costs.

Lower interest-rate expectations may provide some valuation support.

However, weaker earnings expectations could limit that benefit.

Scenario 4: Hawkish Fed + Disappointing Technology Earnings

This would represent the most challenging combination for the AI trade.

Investors could face both less favourable monetary conditions and weaker confidence in future technology profits.

That could affect the Nasdaq, semiconductor stocks and other growth-oriented sectors.

These scenarios are illustrative. Actual market reactions will also depend on expectations already reflected in prices, positioning and broader economic conditions.

9. What Does This Mean for the Indian Stock Market?

The Federal Reserve's decision and Big Tech results can influence India through several channels.

Indian IT Services

Companies such as TCS, Infosys, HCLTech and Wipro depend significantly on technology spending by international enterprise customers.

Strong cloud and AI investment can create opportunities for consulting, integration, cloud migration, cybersecurity and application modernisation.

However, rising AI infrastructure expenditure by U.S. technology companies does not automatically translate into higher outsourcing budgets.

Enterprise clients may increase spending in some areas while reducing discretionary projects elsewhere.

Indian IT investors should therefore watch management commentary on enterprise AI adoption, software expenditure and project pipelines.

Foreign Institutional Investment

U.S. interest-rate expectations influence global capital allocation.

A hawkish Federal Reserve could strengthen the attractiveness of dollar-denominated assets and weigh on emerging-market investment sentiment.

A softer policy outlook could help reduce some  financial pressure.

Nevertheless, capital flows also depend on company earnings, valuations and broader risk appetite.

Indian Rupee

The dollar and U.S. Treasury yields can influence currency markets.

Higher U.S. rates may support the dollar, while lower expected rates can reduce some of that support.

However, India's exposure to imported crude oil creates another important factor.

Oil prices above $115 per barrel can increase import-related pressures and affect inflation expectations.

Indian Technology and Electronics Manufacturing

Microsoft, Alphabet and other cloud companies purchase substantial quantities of semiconductors, networking equipment and supporting infrastructure.

Changes in their investment plans can influence global electronics supply chains.

Indian manufacturers with direct exposure to those supply chains may eventually experience changes in orders or investment opportunities.

However, any benefit depends on company-specific capabilities and customer contracts.

10. Six Indicators to Watch After the Announcements

Tonight's headlines will provide the first reaction, but the more meaningful investment signals may emerge from the details.

Federal Reserve statement: Examine whether policymakers change their assessment of inflation, employment and economic activity.

Fed Chair's commentary: Watch for guidance about the likelihood of further policy tightening.

U.S. 10-year Treasury yield: A sustained change may indicate that investors have meaningfully revised their expectations for growth, inflation or monetary policy.

Microsoft Azure growth and free cash flow: These numbers can reveal whether AI demand is supporting profitable cloud expansion.

Alphabet's Google Cloud and Search performance: Investors will evaluate both AI growth opportunities and the resilience of the company's core advertising business.

Nasdaq and semiconductor-sector breadth: Determine whether any rally is broad-based or concentrated in a small number of influential technology  stocks.

11. LiveWorldMarket Insight: The AI Trade Faces Two Different Tests

The most important observation is that tonight's events are testing two different assumptions behind technology valuations.

The Federal Reserve will influence the cost of capital and financial conditions.

Microsoft and Alphabet will provide evidence about the revenue and cash-flow potential of large AI investments.

Both are necessary to understand the sustainability of the current technology rally.

A company can report strong revenue growth but still disappoint investors if its capital expenditure is rising too quickly.

Similarly, lower interest rates can support valuations without correcting weak underlying business economics.

Investors therefore need to examine the interaction between financing conditions and corporate financial performance.

This is particularly important after the recent volatility in technology shares and the renewed rally in semiconductors.

The next phase of the AI bull market may depend less on the amount companies are spending and more on how much financial return that spending generates.

12. Final Takeaway: Can the AI Rally Survive Tonight's Double Test?

The Federal Reserve's October 28 decision and the latest Microsoft and Alphabet earnings represent an important test for global technology markets.

The Fed is widely expected to leave its target range unchanged at 3.75%–4.00%, but its language on inflation and future policy will influence bond yields and investor sentiment.

Meanwhile, Microsoft and Alphabet are expected to demonstrate strong growth in their cloud businesses.

The key question is whether that growth can justify the enormous investment required to support artificial intelligence.

For Indian investors, the implications extend to IT services, foreign portfolio investment, the rupee and businesses connected to global technology infrastructure.

The strongest evidence of a sustainable AI investment cycle would be a combination of resilient demand, improving profitability, manageable financing costs and healthy cash flow.

Tonight's biggest question is not simply whether the Fed holds rates or whether Big Tech beats earnings forecasts. It is whether financial conditions and corporate profits can jointly support the next stage of AI growth.

The answers will help shape global market sentiment heading into October 29.
