To The Moon

Two technology giants are reporting earnings, but the biggest question may not be how quickly their AI businesses are growing. It is whether AI will strengthen their existing business models or gradually undermine them.

Microsoft and Alphabet are both investing heavily in artificial intelligence. Yet their biggest opportunities and risks are different. Microsoft wants AI to make its enterprise ecosystem more valuable, while Alphabet must grow its AI business without weakening the search and advertising engine that has powered its profits for years.

That difference could become increasingly important as investors assess their long-term growth prospects.

1. Google’s challenge: Protecting the search cash machine

Alphabet’s traditional strength is its ability to connect users with information and advertisers with potential customers.

AI is changing that relationship.

Instead of entering a search query, clicking through several websites and comparing results, users can increasingly ask AI tools to summarise information and provide direct answers.

This creates an important challenge for Google. If users receive more information directly from AI-generated responses, the company must find effective ways to monetise those experiences without damaging the user experience.

AI could also create opportunities. More sophisticated search tools may attract users, improve relevance and support new advertising formats.

The earnings question is whether Alphabet can demonstrate that its AI investments are strengthening its core business rather than simply adding costs.

I would focus on three indicators:

• Search revenue growth: Is the core advertising business remaining resilient?

• AI monetisation: Can AI-powered search experiences generate commercially attractive revenue?

• Google Cloud profitability: Can Alphabet build a second major earnings engine beyond advertising?

Alphabet does not need AI to replace Search to succeed. But it does need to show that its business can adapt as user behaviour changes.

2. Microsoft’s opportunity: Selling AI to customers it already has

Microsoft approaches the AI market from a different position.

Its enterprise software, productivity tools and cloud services already have established customer relationships. That gives the company opportunities to introduce AI products to businesses that already use its ecosystem.

If customers pay more for AI-enhanced productivity software or expand their Azure consumption, Microsoft could increase revenue from existing relationships rather than depending entirely on finding new customers.

However, adoption alone does not guarantee success.

Businesses must see enough productivity gains to justify additional subscription costs. If AI tools are expensive to operate but customers are unwilling to pay a meaningful premium, the financial returns may disappoint.

Investors should therefore look for evidence that AI is increasing paid usage, strengthening customer retention and supporting profitable cloud growth.

The distinction is important: impressive demonstrations can generate excitement, but repeatable commercial demand creates a business.

3. The hidden risk: AI could disrupt both companies

It would be a mistake to assume Microsoft is automatically protected or that Alphabet is destined to lose.

Microsoft faces competition from other cloud providers and AI platforms. Enterprise customers may use several models and services, making it harder for any one provider to capture all the value.

Alphabet faces pressure to adapt Search, but it also possesses extensive distribution, infrastructure, data capabilities and advertising relationships.

Both companies must invest continuously to remain competitive. If AI capabilities become easier to replicate, some of today’s spending advantages could narrow over time.

The companies that succeed will need more than advanced models. They will need distribution, customer loyalty, efficient infrastructure and the ability to turn technical improvements into revenue.

4. What would make the earnings reports genuinely bullish?

For Alphabet, I would look for resilient Search growth alongside evidence that AI features are commercially viable. Strong Google Cloud growth would add another source of confidence.

For Microsoft, I would look for healthy Azure demand and signs that AI products are contributing meaningful revenue without placing excessive pressure on margins and cash flow.

For both companies, management’s spending plans matter. Higher capital expenditure is not necessarily negative if it supports attractive future returns. The concern arises when investment rises sharply but management provides little evidence of corresponding commercial benefits.

Investors should also consider valuation. A strong business can still deliver disappointing share-price returns if expectations were already too optimistic.

My takeaway

The AI competition is becoming a test of business-model resilience.

Microsoft needs to demonstrate that AI can increase the value of its enterprise ecosystem. Alphabet needs to show that it can monetise AI while protecting the economics of Search and expanding Google Cloud.

Both have substantial opportunities, but their paths to success are not identical.

The most revealing earnings signal may be whether AI is creating new revenue without undermining the profitable businesses that fund the investment.

That is the distinction I would watch: not simply which company spends more on AI, but which company demonstrates the clearest path from technological progress to durable earnings growth.

For discussion purposes only. This is not financial advice.
