Nvidia is investing $3.5 billion in convertible bonds issued by Taiwanese chip designer MediaTek, deepening a long-standing partnership in AI chips, PC processors, and automotive technology. The agreement, announced Monday, is part of a total bond offering of $3.9 billion that also includes Alphabet. Nvidia’s stock reacted with a drop of nearly five percent.
MediaTek issues $3.9 billion in convertible bonds
Nvidia and MediaTek announced the investment Monday in a joint statement. MediaTek is placing zero-coupon convertible bonds worth $3.9 billion in total, of which Nvidia is subscribing to $3.5 billion. Because the bond pays no ongoing interest, MediaTek mainly carries the risk of future dilution for existing shareholders if bondholders later convert. The companies did not disclose further terms on how the proceeds will be used. According to a report by Crypto Briefing, Google parent Alphabet is also participating in the bond without disclosing its own amount. The conversion price is said to sit roughly 115 percent above MediaTek’s share price on the issue date – meaning bondholders are betting on a substantially higher price before converting into shares makes sense. The bond is set to close on September 8 and subsequently list on the Singapore Exchange. MediaTek is Taiwan’s largest chip designer and has been pushing from its traditional smartphone business into data-center AI chips since a $5 billion financing plan was approved in July, a market so far dominated by Nvidia itself along with AMD and Broadcom.
NVLink Fusion opens Nvidia’s data centers to outside chips
At the core of the deepened partnership is NVLink Fusion: MediaTek is adopting the platform so customers can develop their own AI accelerators, known as XPUs, and integrate them into Nvidia’s networked data-center racks. The technology combines NVLink Fusion chiplets, the NVLink-C2C interconnect, and Nvidia’s NVHBM memory standard into a prebuilt toolkit meant to give cloud providers, hyperscalers, and developers of their own AI models a prevalidated development path instead of building each connection from scratch. Nvidia CEO Jensen Huang said, according to the statement, that AI is transforming every computing platform. MediaTek CEO Rick Tsai stressed that the partnership spans cloud infrastructure, local AI computing, and the automotive industry. In practice, that means the two companies are jointly developing several more generations of the RTX Spark and DGX Spark PC and developer chips, which pair Nvidia GPUs with MediaTek chips for laptops, AI workstations, and developer systems. In automotive, the companies are continuing their collaboration on MediaTek’s Dimensity Auto platforms for software-defined, AI-powered vehicles – a field where MediaTek already works with Nvidia today and one gaining importance as autonomous driving features spread.
Investors fear circular financing in the AI industry
Despite the multibillion-dollar alliance, Nvidia’s stock closed nearly five percent lower at $217.55 on the announcement day, while MediaTek shares on the Taiwan Stock Exchange briefly fell about 1.5 percent. According to Bloomberg reporting, the trigger was renewed concern about circular financing: Nvidia keeps pumping billions into companies that are simultaneously among its most important customers and suppliers, including, just in August, a $105 billion guarantee for an OpenAI data center in Ohio and a $500 billion financing initiative for external AI data centers. The price of five-year credit default swaps on Nvidia bonds is said to have risen that day by more than at any point on record – a sign that investors are reassessing Nvidia’s debt risk and viewing its entanglement with its own customers more critically than just a few months ago. Critics see the pattern as a signal that part of current AI demand rests on Nvidia’s own capital rather than independent customer demand – an assessment that is not independently verified and that Nvidia itself has not commented on.
What matters now is whether this pattern of repeated stakes in customers and suppliers continues even as Nvidia simultaneously funds billions in outside AI infrastructure. The MediaTek bond’s closing on September 8 and its subsequent Singapore listing offer an early test of whether investor concern about circular financing fades or hardens further once both companies report their next quarterly results.
