$3.5 Billion Into Custom Silicon
Nvidia is investing $3.5 billion in Taiwanese chipmaker MediaTek through convertible bonds, a deal that gives MediaTek access to Nvidia’s NVLink Fusion ecosystem for building custom AI chips that plug into Nvidia-based data centers.
MediaTek shares jumped about 10% on Tuesday following the announcement, extending a roughly 200% rally year-to-date. The chipmaker, the world’s biggest smartphone chip company by market share according to Counterpoint Research, has been working to diversify into data center chips for AI workloads. The partnership lets it build custom silicon for hyperscalers while staying connected to Nvidia’s dominant infrastructure.
“Basically, every cloud, every model builder is deploying our platform in some shape, form, or fashion,” Nvidia senior director Dion Harris said on a press call Monday. “So by MediaTek being able to offer this extension to its customers, it allows them to standardize on the rack-scale infrastructure across their AI factories.”
NVLink Fusion and the Custom Chip Race
The core of the deal is NVLink Fusion, Nvidia’s technology that lets any chip, including those made by other companies, communicate quickly within a data center. Under the partnership, MediaTek can offer NVLink Fusion to customers developing custom AI chips, meaning those semiconductors can sit alongside Nvidia GPUs in the same rack using the same interconnect standard.
The move comes as Amazon, Google, Microsoft, OpenAI, and Anthropic invest heavily in building their own chips to reduce reliance on Nvidia’s GPUs. Amazon has its Trainium and Inferentia lines. Google has its TPU series. Microsoft launched its Maia chip last year. OpenAI is developing its Jalapeno chip. Anthropic has been discussing custom silicon with Samsung.
Rather than fight that trend, Nvidia is positioning itself as the connective tissue between all these custom efforts. Deals like the MediaTek partnership let Nvidia cede ground on individual chip designs while maintaining its lead as the dominant data center scaffolding. The company has argued for years that it is not just a chip company but an infrastructure company, and the MediaTek deal is the clearest evidence yet of that broader strategy in action.
“This is really about opening up this ecosystem to the entire MediaTek customer base,” Harris said.
Beyond Data Centers
The partnership also covers consumer PCs and automotive platforms. MediaTek and Nvidia will extend their collaboration on the DGX Spark, Nvidia’s desktop AI computer, into the RTX Spark for consumer AI PCs. The companies also signed a deal with Amazon last week to deploy an additional 2 million GPUs across AWS infrastructure and integrate NVLink Fusion, though that partnership did not include a direct investment.
On the automotive side, MediaTek’s auto platforms will continue using Nvidia’s RTX graphics for intelligent vehicle cockpits alongside Nvidia Drive AGX for autonomous driving workloads. “AI is transforming every computing platform, from the world’s largest AI factories to the PC and the car,” Jensen Huang said in a statement.
MediaTek expects its custom data center chip business to generate $2 billion in revenue in 2026, the company said in June. The Nvidia deal could accelerate that trajectory by giving MediaTek’s custom chips access to Nvidia’s broader data center ecosystem and the rack-scale architecture that underpins it.
The Investment Pattern
The deal fits Nvidia’s broader pattern of investing in companies that feed back into its own ecosystem. Critics of the model note that when Nvidia funds the companies buying or amplifying its technology, revenue and investment begin chasing each other in a circle. The convertible bonds give Nvidia a future equity stake in MediaTek if the shares appreciate further, deepening the financial interdependence between the two firms.
For MediaTek, the deal provides both capital and credibility at a critical moment. The company has been slowly building its custom data center ASIC operations, but the Nvidia partnership gives it a stamp of approval that could open doors with hyperscaler customers who might otherwise default to Nvidia’s own chips or those from competitors like Intel and Marvell.
The competitive dynamics are shifting across the semiconductor industry. U.S.-China tensions have reshaped supply chains, while the AI boom has created demand for custom chips that general-purpose GPUs cannot always satisfy. Nvidia’s strategy of investing in the ecosystem around its GPUs, rather than trying to own every chip in every data center, could prove to be the more durable approach over time.
The announcement came alongside MediaTek’s release of quarterly results showing strong demand for its mobile and connectivity chips. The data center push adds a new growth vector to a company that has traditionally been known for smartphones and consumer electronics products.
Market Reaction
MediaTek’s stock closed at TWD 4,315 on Tuesday, up 9.94% for the day. The convertible bond terms were not disclosed beyond the $3.5 billion principal amount. The deal gives Nvidia a potential equity position that could grow significantly if MediaTek’s data center business hits its ambitious revenue targets in the coming years.
Nvidia shares were roughly flat on the news, reflecting the market’s view that the investment is strategically sound but not transformative for a company with a $4 trillion market capitalization. The bigger story may be what the deal signals about the future of AI infrastructure: a world where Nvidia’s ecosystem is so deeply embedded that even companies building competing chips need to plug into it.
The Taipei Times first reported the deal terms on Monday, with Bloomberg and CNBC confirming details the following day.
