Nvidia.
Can you characterize how big and how dominant Nvidia is?
Robby Whelan
Yeah, Nvidia. Most people think that Nvidia controls 90% or more of the advanced AI chip market.
Ryan Knudsen
That's our colleague Robby Whelan. He covers tech.
Robby Whelan
And I can't think of another industry where there's such a market concentration. It's not that Nvidia has chased out the competition or had some sort of nefarious strategy to make it impossible for people to compete with them. It's that they were very early first movers in this idea that these chips that used to be primarily used for video games were also really, really good for doing AI computing.
Ryan Knudsen
As the AI industry has boomed, more and more are developing their own AI chips and coming for Nvidia's crown. But the company that might have the best shot is a small one, one you've probably never heard of, Advanced Micro Devices or amd.
Robby Whelan
So AMD is very much the David to Nvidia's Goliath and the CEO of amd, a woman named Lisa Su. She has a really good track record of slaying giants. She's done it before, but she's never met an opponent like Nvidia. Nvidia is truly a Goliath here. And the idea that she's going to take them on, it's very audacious and it's very exciting for a lot of people who watch this industry.
Ryan Knudsen
When Lisa Su took over AMD a little over a decade ago, its market cap was less than $3 billion. Now AMD is worth more than 350 billion, and there's no sign of slowing down. A few weeks ago, AMD scored a major coup when it inked a massive chips deal with OpenAI. Recently, Robbie sat down with Su to talk about the deal, the company, and why she believes we're only scratching the surface of the AI revolution.
Robby Whelan
Where are we in terms of focus right now about going forward and how to get to where you want to be? And where is that that you want to be?
Lisa Su
Well, we are in a very special time, so we are probably going faster than we've ever gone before. I mean, I certainly believe that the technology is moving faster than I've ever seen in my career. And the role of AMD is to enable all of that with the foundational computing.

Ryan Knudsen
Lisa Su rose through the chips industry as an engineer. Early in her career she worked at IBM in Texas Instruments.
Robby Whelan
She's an engineer who has a PhD in electrical engineering from MIT. She's deeply interested in what's called device physics, which is sort of the marriage of gadgets and hard science. So she understands how a piece of silicon inscribed with transistors translates into the computing power that appears on your screen when you're a software developer. She understands it perfectly.
Ryan Knudsen
Su joined AMD in 2012 and took over as CEO two years later. And soon after she earned a reputation for making bold bets.
AMD is an American company that's been a long time player in the chip space. It was founded in the late 1960s and it's based in Santa Clara. When Su joined the company in 2012, it was mainly focused on chips for individual computers and electronics known as CPUs. But when she took over as CEO two years later in 2014, she saw some holes in AMD's strategy.
Robby Whelan
She looked at the product line of what AMD was making and she said, we're not focusing on the right things. We need to be focused on accelerated advanced computing because that's what our customers want. She would go to these meetings and they would say it's great that you guys make computer chips that power PCs or mobile devices, but what we really want is a data center server that can help us take our products to the next level. Okay, so she totally revamped AMD's product line and and AMD started making these chips that are essential to the data center.
Ryan Knudsen
Su started focusing on the chips that were critical for cloud computing, an area that exploded over the last 15 years. And the strategy paid off, and it helped AMD become a major player in a market that had long been dominated by Intel.
Robby Whelan
She positioned herself in a way that she was in the data center. She ate up Intel's market share in data center computing, and she really leapfrogged Intel.
Ryan Knudsen
But the pivot proved consequential for another reason. It gave AMD a foothold in data centers, which had become critical in the rise of AI. After the launch of ChatGPT in 2022, sue saw an opportunity to pivot the company again.
Robby Whelan
They were having a board meeting in late 2022. And so she comes to this board meeting and she says, look, I've had this epiphany. I'm going to pivot the entire company. She says, you know, artificial intelligence is rising. It's a once in a lifetime opportunity, and we are positioned in a very special way for us to take advantage of that. She said, we're going to revamp our entire product line so that it's now all oriented around artificial intelligence. And this was a major turning point.
Ryan Knudsen
This time, sue wanted to take aim at Nvidia.
Back then, Nvidia wasn't a household name, but it was clear to sue that it was on the rise.
Robby Whelan
ChatGPT was trained, trained on Nvidia's chips. It took seeing a product like ChatGPT for most people in the world to realize how big Nvidia was going to get, how big AI was going to get. And I think that that was the real talent that Lisa Su has that shined through in this moment. She said, this is going to change everything and we have to be in front of it.
Ryan Knudsen
We're going to bet the whole company on it, basically.
Robby Whelan
Exactly. We're betting the whole company on it.
Ryan Knudsen
By the way, Nvidia CEO Jensen Huang and Su were actually distant cousins. They only met as adults.
Fast forward, you know, two to three years. How does that pivot go? Like, what does she actually do?
Robby Whelan
She goes top to bottom and revamps AMD's entire product line. She rolls out three or four generations of what's called the Instinct series GPU. So this is the first time that AMD is in the modern era, in the AI era, is directly competing with Nvidia. And to be honest, they have a hard time competing with Nvidia. I mean, the first few generations of the Instinct were generally regarded in the market as not as powerful, not as easy to use as Nvidia's. Equivalents. But that's okay for a company like amd because what they're doing there is they're trying to get a foothold, they're testing out these products, they're. And they're trying to find customers to sign up and commit to using them.
Ryan Knudsen
To take on Nvidia, Su decided to focus on chips that were one step ahead. Rather than making chips that are good at training AI models, which has dominated the AI market so far, sue wanted to make chips that were good at inferencing. What does that mean? What is inference computing?
Robby Whelan
So in AI computing, there are two main chips functions that people need to utilize. When you're developing an AI model or an AI tool, whatever it is, be it a chatbot or a video generation app, you have to first train it and then you have to make it capable of responding to queries, which is to say you have to run it. And the running it is usually referred to as inference. Inference computing. Inference is when you or I sit down and says, hey chatgpt, what should I eat for lunch today? And spits out a few recipes for us, that is inference. It's querying the models and it's running.
Ryan Knudsen
Them at its most basic. The training is the learning part or when an AI model is devouring everything it can, and the inferencing is the doing the actual responding to prompts.
This decision is starting to pay off. In October, AMD announced that massive deal with OpenAI to help it run inference functions for ChatGPT.
Under the deal, OpenAI agreed to buy a ton of AMD chips starting next year. And in return, OpenAI could get as much as a 10% ownership stake in AMD.
Robby Whelan
And when this announcement was made, AMD's stock shot through the roof. They saw huge gains in their share price and everyone was very excited about it.
Sponsor Voice
Shares in the chipmaker AMD have surged over 30% today on news of a.
Robby Whelan
Huge new tie up with Open Air. And basically the reason why everyone was so excited was because here you had the what most people regard as the best company in AI development, which is OpenAI not jumping ship entirely from Nvidia, but saying, look, AMD is just as good for us to operate our models so we can use their chips. You can pay them a tremendous amount of money to buy them. And it's not just Nvidia anymore. They're not the only game in town.
Ryan Knudsen
Yet amid all the excitement and money, there's also concern about an AI bubble. And the AMD deal with OpenAI raised questions among some investors, the AMD OpenAI.
Robby Whelan
Deal, it wasn't all sunshine and roses. There were some concerns as well that came up and they surrounded the financing of the deal and they sort of pointed to this idea of is this really a wonderful deal for everyone involved, or does it maybe indicate that we might be in a huge, dangerous financial bubble surrounding AI?
Ryan Knudsen
After the break, Robby sits down with Lisa Su to talk about the concerns about an AI bubble.

Recently, Robby flew to a big AMD office in Austin to meet with Lisa Su.
Robby Whelan
So can you just start by telling me your, say your name and title and where you grew up and how long you've been in your current role?
Lisa Su
Lisa Su, CEO of AMD I grew up in New York, born in Taiwan, grew up in New York, and I've been in this role. I joined AMD in 2012.
Ryan Knudsen
One of the main things Robbie wanted to talk with sue about is the AI bubble and specifically whether AMD's deal with OpenAI might contribute to that bubble. Under the terms of the deal, AMD gave OpenAI a big financial incentive to use its chips. If OpenAI hits certain milestones for deploying AMD's chips, it has the option to buy AMD shares at a steep discount at just $0.01 per share.
Robby Whelan
If you're wondering why it sounds like money's going out the door from AMD to a customer and then coming right back in the door to buy their chips, it's because this is an example of what people have recently started describing as circular funding or circular financing. Circular finance.
Ryan Knudsen
Circular financing.
Lisa Su
Circular financing.
Announcer/Advertiser
The circular financing. Right. Where these companies are lending to other companies who are going to be buying their products.
Robby Whelan
And so with the amounts of money that are being tossed around, the numbers that are being tossed around, when people see circular financing, you know, they get. They start to get worried. They start to think, is this a bubble? Is this all going to come crashing down? Are these. Are these companies ever going to be profitable? And are the. Are the people who funded them going to totally lose their shirts?
Ryan Knudsen
Sue defended the deal in her conversation with Robby.
Lisa Su
We structured this deal so that there was complete alignment of incentives, complete alignment, that we wanted to go fast, that we wanted to go big, and that if OpenAI is successful, AMD is successful because they will need lots of GPUs. And the opposite is also true, which is, if AMD is successful, OpenAI gets to share in some of that upside.
Robby Whelan
Given the current phase that we're in of the AI boom and the market conditions, do some of these big deals have to be done in this way that feel sort of circular to investors?
Lisa Su
Look, I don't think you have to do anything. I think people make choices. There are plenty of deals where we are basically selling GPUs. I think the opportunity is to partner deeply in the ecosystem. There are different opportunities to do that, and we've chosen a mechanism which I think really ties the companies together in a way that they care about my success, I care about their success, and everyone wins in this fashion. If, for whatever reason, the GPUs are not deployed, then there's also no equity that goes along with it. From that standpoint, I just view it as a way to tie ourselves closer together. And I think that's actually a good thing.
Robby Whelan
But if I were an investor, I could see myself thinking, this is great. The stock price is going up, it's accretive, but I kind of wish we didn't have to give away 10% of the company to get it done. What would you say to investor who said that?
Lisa Su
I would say you're probably undervaluing the importance of the partnership, that it is not a pure transactional relationship. It's one where we are, you know, deeply developing the future of AI, and that's highly valuable.
Ryan Knudsen
Is she at all concerned about an AI bubble?
Robby Whelan
Yeah. So I said to her, a lot of people are saying that your deal with OpenAI is going to contribute to the sense that there's a bubble. And her response was, essentially, I'm not worried about an AI bubble. And she repeated this mantra she has, which is, basically, there's insatiable demand for computing. And that's why I'm so confident that even if it takes unusual, unorthodox financing at the outset, that things are going to turn out okay and that we're going to benefit in a big way from all this demand.
Lisa Su
We should see this kind of investment because this technology does have so much potential and we are barely scratching the surface. And frankly, what I'm seeing is the people who are being rewarded are those who are willing to take big, bold bets. And this is not the time to stay on the sidelines and worry, hey, am I over investing? It's much more dangerous if you underinvest than if you over invest, in my opinion.
Ryan Knudsen
Sue says that once AI models are up and running and people start relying on them, there'll be almost no limit to the future demand for AI computing. She estimates that the overall market for AI could be worth $1 trillion a year. But isn't sue, the head of an AI chips company, going to say that there's never ending demand for chips? The thing I happen to be selling?
Robby Whelan
That's exactly right. So the bear case here is that OpenAI and other similar customers are going to spend way too much money on silicon, and then they're going to never produce the kinds of profits and revenues that people expect them to.
Announcer/Advertiser
And.
Robby Whelan
And everyone kind of, kind of goes down in flames because. Because everyone up and down the supply chain, including the people who are supplying the silicon to, to these software developers and the backbone of this computing power that everyone needs right now, that that demand will evaporate when eventually the gravy train stops and people realize that, you know, there's not enough demand in the market for the end product. And so everyone up and down the supply chain suffers. And you can easily see a world where if the bubble did pop, if there is a bubble, and if it does pop, then companies like AMD and Nvidia will really be directly in the firing line.
Ryan Knudsen
For amd, the big money will be coming from inferencing the space she's pivoted the company toward.
Lisa Su
Inference is where the payoff is. It's actually where the money is, because inference says that you have a model that's good enough, and now you're just deploying, deploying. You have thousands of agents, tens of thousands of agents there are. They're all asking questions, and you need to be able to support all that. So I think when you see inference grow, that actually means AI is having an impact in the world. And because we see so many different applications, yes, I think this is a place where the battlefield will be around. How do you really serve inference in the most efficient, effective way?
Ryan Knudsen
The pivot to inferencing is something other chip makers are also thinking about, including Nvidia. Its CEO, Jensen Huang has estimated that as much as 90% of the market for computing power will be for inference computing.
Nvidia has signaled that it welcomes competitors. It also said on X that it was, quote, a generation ahead of the industry.
AMD isn't the only company trying to break into the AI chip business and cut into Nvidia's dominance in the market. Other chip makers like Broadcom and Qualcomm have also emerged as competitors designing their own AI chips and data center tech. Silicon Valley giants outside of the chip world are also entering the space. Google is selling access to data center chips it previously reserved for internal use only. And Amazon has started selling chips it says are faster and more energy efficient than Nvidia's.
Robby Whelan
There's a lot of entrance in this market and so, yeah, this has implications for amd. I mean, Lisa Su is probably sitting there and watching and saying, hmm, that's, that's interesting. That's going to make our lives more complicated. But maybe it does also validate her view that this market is really just so big that it requires a lot more suppliers.
Ryan Knudsen
Do you think AMD will be able to catch up to or even pull ahead of Nvidia?
Robby Whelan
I think that's very unlikely. I think that Nvidia's lead is so significant.
But there is a clue in the deal she made with OpenAI. There was a clue in the fine print of it about one of her goals and that was that under this deal, OpenAI only gets the full 10% of AMD's stock if AMD stock reaches $600 a share, which would imply that the full market value of AMD was $1 trillion. So in other words, she wrote this deal with OpenAI in a way that incentivizes the company to become a trillion dollar company.
Ryan Knudsen
So it sounds like she's sort of saying that a rising tide lifts all boats, that there's space for AMD to be worth a trillion dollars and Nvidia to be worth four and a half trillion dollars because we're just going to need all this computing power for the AI revolution.
Robby Whelan
That's exactly what she's saying.

This episode dives into the battle for dominance in the AI chip market, spotlighting Advanced Micro Devices (AMD) and its CEO, Lisa Su. While Nvidia currently maintains a commanding lead in advanced AI chips, AMD—under Su's bold leadership—has not only closed the gap significantly but made strategic moves to position itself as Nvidia’s main rival. The hosts and Robby Whelan explore Lisa Su’s journey, pivotal decisions, and their most recent $10B deal with OpenAI, examining what this means for the AI industry, concerns of an AI bubble, and AMD’s future ambitions.
The episode paints a vivid picture of seismic shifts underway in AI hardware—dominated (for now) by Nvidia, but with AMD, led by Lisa Su’s bold vision and risk-taking, carving out a formidable challenger path. Key industry questions remain about the sustainability of the AI boom, the wisdom (or risk) of circular financing, and whether the market is truly big enough—or overheated. Su’s central argument: betting big on a boundless future of AI isn’t just smart, it’s necessary—and AMD intends to play a central role.
For listeners, this episode delivers crucial context on how the AI computing landscape is evolving, the high-stakes nature of the AMD–OpenAI partnership, and the personalities driving this pivotal business rivalry.
