Nvidia has put $3.5 billion into the Taiwanese chipmaker MediaTek, snapping up the bulk of a record $3.9 billion bond sale that also drew in Alphabet. On its own, the deal deepens a partnership that already spans AI data centers, PC chips, and automotive tech. But it landed with a familiar thud on Wall Street, where Nvidia’s own shares fell around 5%, because it is the latest entry in a pattern that has investors increasingly uneasy: Nvidia keeps writing large checks to the companies that fuel demand for its products.
That unease has a name now, circular financing, and Nvidia’s chief executive Jensen Huang went out of his way to reject it. “This is not circular,” Huang told Bloomberg, arguing that Nvidia and MediaTek each run their own separate businesses. Not everyone is convinced. The deal follows a $30 billion stake in OpenAI earlier this year and a $105 billion backstop for an OpenAI data center just two weeks ago, and the short-seller Michael Burry summed up the skeptics’ view in four words: “whistling past the graveyard.” A Bernstein analyst put it more plainly, saying the move would “clearly fuel” circular-financing concerns.
What the deal does
Look past the money and the strategy is clever, which complicates the simple “it’s a bubble” read. The centerpiece is NVLink Fusion, Nvidia’s proprietary technology for connecting chips inside a data center. By financing MediaTek to adopt it, Nvidia is enlisting one of the world’s biggest chip designers to help make its interconnect the industry standard. As more companies build their own custom AI chips, a trend Nvidia cannot stop, it is instead positioning itself as the indispensable wiring that all those chips plug into.
That is why some analysts call this less circular than Nvidia’s other deals. It is not simply lending a customer money to buy Nvidia chips; it is paying a partner to extend Nvidia’s architecture. The structure is telling, too. Nvidia bought convertible bonds, which give it downside protection as a creditor plus upside if MediaTek does well, and its return climbs highest if NVLink Fusion becomes the fabric everyone builds around. The investment and the ecosystem dominance are the same bet.
Clever, but the pattern is real
Here is where both things can be true at once. Financing MediaTek to entrench your interconnect is smart, defensible strategy. It is also, undeniably, Nvidia using its enormous balance sheet to manufacture demand and lock in its ecosystem, which is exactly what critics mean when they warn about a self-reinforcing loop. When the same company supplies the chips, funds the buyers, and bankrolls the partners, the growth can start to look like it is feeding on itself, and a stumble anywhere in the chain ripples everywhere.
MediaTek, for its part, gets validation and capital to push beyond smartphones into data-center AI, a market it thinks could be worth $70 billion or more by 2027. For Nvidia, this is one more thread in a web it has been weaving all year.
So is Huang right that this is not circular, or are the skeptics right that it is more of the same? The honest answer is that it is truly both, a sound strategic move and a fresh data point for the bubble worriers. Nvidia can keep making deals like this one for as long as the AI boom holds. The question that keeps dragging its stock down is what happens to all these interlocking bets if it does not.
