CNBC's Deirdre Bosa reports on the AI leaderboard.

The release of Open AI's ChatGPT has accelerated the development of artificial intelligence and warnings about its impact on society.

Rise of AI

Google has rapidly advanced its position in the artificial intelligence sector after the release of Gemini 3 and the deployment of its custom TPU chips. These developments have contributed to a shift in perception, with Google now seen as a leader in AI execution and distribution at scale. 

While Google's TPUs are gaining traction, their closed nature limits enterprise flexibility, making the broader AI market competitive rather than winner-take-all. Amazon, despite being the largest cloud provider, has struggled to match Google's momentum in both custom AI chips and model performance, with its "Trainium" chip and "Nova" models lagging behind.

Now that big AI shift is where we start today and we've got some team coverage. Deirdre Bosa looking at how Google is building out its AI ecosystem. Christina Parts of Neville's is digging into how that's impacting the supply chain. And Julia Boorstin has the Mag 7 stock that can't seem to find its AI footing. Deirdre we're going to start with you. So Dom and AI the leaderboard it changes fast and narratives they can swing harder than the fundamentals. Just look at Google. It went from broken to beloved in a matter of months not even because the business changed that dramatically. Now it's on top now because it started executing Gemini 3. Its model landed TPUs its custom AI chips. They're gaining traction and Google is shipping AI at a Google scale. It has the distribution. But just as markets got over their skis on the other side of this trade this probably is not a winner take all situation. Take the emerging chip narrative. Yes Meta buying Google custom chips powers the alphabet bull story. But the narrative that TPUs are about to overtake NVIDIA across the enterprise. Not so fast. TPUs you have to remember this. They lock you into Google stack. So they only run inside of Google Cloud for most enterprises. That is a tough sell. They want optionality to be able to plug into NVIDIA or AMD or whatever comes next. There's room for both essentially. So the real fight isn't Google versus NVIDIA. It may actually be Google versus the other hyperscalers TPUs. They strengthen Google Cloud against the number one and number two hyperscalers Amazon and Microsoft. And it raises the question if Google has all of this momentum and custom silicon right now where's the pickup for Amazon's chip training. All right. So again since you open the door for this D where is Amazon exactly in this race since it is the biggest cloud computing player out there and a hyperscaler itself. It's the biggest cloud computing player out there the number one hyperscaler. So it should be leading in A.I. right. And what we're learning from Google is that having your own custom chip is a huge part of that. We know that Amazon has been working on its own set of custom A.I. chips. The most well known is train him and even signed a deal with Anthropic. But it's you know not a very well kept secret that there's disappointment not just on Wall Street but in tech circles with that chip. It certainly does not have the momentum that Google does. And that's just on the chip side. Dom I bet you'd be hard pressed to name you know Amazon's family of A.I. models. Most people would. It's Nova by the way. But they're not climbing the leaderboards and that gap between sort of Google and everyone else not just Amazon by the way has been increasing in recent months or at least the narrative has. It's always been there. They're executing. And Wall Street is now appreciating.
