The Top 3 Risks Alphabet Investors Should Not Ignore

Alphabet (NASDAQ: GOOGL) (NASDAQ: GOOG) is one of the most dominant companies in the world, powering everything from global search to mobile operating systems to the internet's underlying infrastructure. For long-term investors, it is one of the safest stocks on the market.

But even giants carry risks, and Alphabet's most significant challenges aren't short-term headwinds. They are structural, slow-building forces that could influence how the company performs over the next decade.

Here are the three most essential risks investors need to keep on their radar.

1. A structural shift in how people search for information

For the first time in two decades, Alphabet's core business model faces a fundamental challenge. Generative artificial intelligence (AI) and intelligent agents are transforming how people retrieve information, and this shift has a direct impact on the company's economics.

On the main level, AI reduces the need for traditional search queries. Instead of typing into a search bar, users are increasingly asking AI systems to answer questions, summarize complex content, or perform tasks directly. This new business model differs significantly from the one Google Search uses for monetization.

The threat isn't an overnight collapse; it's a decade-long erosion of:

• query volume
• ad impressions
• click-through behavior
• and the value of the commercial intent that powers Google's margins.

Alphabet is innovating, but it must also protect its cash engine, making it highly vulnerable to its competitors like OpenAI and Perplexity. These newcomers can pursue AI-first interfaces without worrying about cannibalizing a huge ad business; Alphabet cannot. Every AI enhancement must strike a balance between enhancing user experience and protecting multibillion-dollar revenue streams.

This tension makes search transformation far riskier for Alphabet than it is for newer AI-native platforms.

In other words, how well it adapts to the change in search behavior will decide how much it can defend (and grow) its search business's profitability.

2. Regulatory pressure is intensifying

One of the most significant risks that the company faces is its own success, since it attracts the attention of parties who initially have little interest in it. Among these, the regulators are becoming a significant hurdle for its ongoing growth.

Particularly, Alphabet's significant dominance in areas such as search, Android, and handling huge amounts of data has become a target for regulators in various regions. If they force changes -- for example, banning default search agreements, requiring Android to let users select their search provider and browser during set-up, or breaking up ad-tech units -- the company could lose crucial advantages that have taken decades to build.

This is a risk that will not go away -- arguably, it will intensify. Unlike earnings volatility, regulatory outcomes unfold gradually but permanently. They reshape the landscape over years, not quarters, which is precisely why long-term investors must track them closely.

3. Rising competition from AI-native and platform-scale rivals

For years, Alphabet was either a monopoly or a duopoly in many of its businesses. However, its competitive landscape is more complex today than ever before.

The biggest disruptors to watch are AI-native challengers. Start-ups like OpenAI and Perplexity don't carry legacy business models. They can design search alternatives, conversational engines, and agent-based workflows optimized for the future, not constrained by the past.

These companies chip away at user attention and shape new habits. Even a minor share erosion in search or information retrieval can meaningfully impact Alphabet's long-term growth.

And tech giants are aggressively seeking to fortify their core businesses while expanding into new ones -- some of which Alphabet is already operating in. For instance, Microsoft is embedding AI deeply into Windows, Office, and its cloud ecosystem, which will be a challenge to Alphabet's cloud business. Meta, leveraging its billions of global users, is pushing open-source AI models with worldwide reach and cost advantages.

Alphabet still holds enormous advantages in areas such as digital advertising and AI. But the competitive intensity has increased dramatically as all of its major competitors now have credible AI strategies.

In short, while competition may not dethrone Alphabet, it can slow growth, compress margins, and weaken long-term returns.

What does it mean for investors?

Alphabet isn't facing an existential crisis. It remains one of the strongest technology platforms of its time, with enormous reinvestment capacity and global reach.

However, long-term investors should recognize that shifts in search behavior, regulatory restructuring, and AI-driven competition represent meaningful, slow-moving risks that can shape the company's next decade.

Alphabet can still grow, but the path may be bumpier, more regulated, and more competitive.
