Over the next year, Roku predicts that 100% of the streaming audience will see ads. For growth marketers in 2026, CTV will remain an important “safe space” as AI creates widespread disruption in the search and social channels. Plus, easier access to self-serve CTV ad buying tools and targeting options will lead to a surge in locally-targeted streaming campaigns.

Despite all the talk of an “AI bubble,” Warren Buffett’s Berkshire Hathaway just made a massive new bet on the sector—buying 17.8 million shares of Alphabet (Google) worth $4.3 billion. Alphabet is now one of Berkshire’s largest positions.

📈 The Big Story: Buffett Finally Joins the AI Party

Warren Buffett—famous for avoiding hype cycles and sticking to value investing—has surprised the market with a major move into AI infrastructure.

Latest SEC filings reveal that Berkshire Hathaway bought:

  • 17.8 million shares of Alphabet

  • Valued at ~$4.3 billion

  • Purchased during Q3 2025

  • Now ranking among Berkshire’s top holdings

This marks one of Buffett’s boldest tech investments since Apple.

🤖 Why Alphabet? Why Now?

Despite fears of an AI bubble, three factors make Alphabet a unique “value” AI play in Buffett’s eyes:

1. The Hyperscaler Advantage

Alphabet is part of the “Big 3” hyperscalers powering global AI workloads:

  • Google Cloud

  • TPU infrastructure

  • Gemini model ecosystem

  • Cybersecurity, ads, and search integration

This gives Alphabet diversified revenue streams beyond just AI models.

2. Dominant Cash Flows

Even if AI margins compress, Alphabet prints cash from:

  • YouTube

  • Search

  • Ads

  • Cloud subscriptions

Buffett loves giant, predictable cash machines.

3. AI Is Becoming a Utility

Buffett invests in long-term infrastructure: railroads, energy, insurance.
AI infrastructure today is starting to look like the next electricity or internet.

Alphabet fits that thesis perfectly.

💬 Market Reaction

Investors reacted instantly:

  • Alphabet shares rose on the news

  • Analysts called it a “validation moment” for AI

  • Many investors see Buffett’s move as a signal AI is underpriced, not overhyped

Some even speculate Berkshire may expand its AI holdings further.

🧠 The Bigger Picture

This move sends a strong message:

If Buffett—the world’s most cautious value investor—sees long-term value in AI infrastructure, the sector may still have years of growth ahead.

The AI race is no longer just about cool demos. It’s about trillion-dollar infrastructure, cloud dominance, and computing power becoming the foundation of the global economy.

🔮 What This Means for the Future

Expect:

  • More institutional money flowing into hyperscalers

  • Accelerated AI infrastructure spending

  • Stronger valuation support for long-term AI players

  • Potential follow-on bets in Nvidia, AMD, Broadcom, or data center REITs

If Buffett is early… everyone else is late.

📢 Final Take

Alphabet just gained the endorsement of the world’s most trusted investor.
While headlines scream AI bubble, Buffett is quietly buying the dip.

And historically—when Buffett makes a big move in tech—it reshapes the market.
