China Hits Nvidia With Monopoly Probe Over Mellanox Deal

​Beijing Drops the Hammer
China’s market regulator says Nvidia broke anti-monopoly laws tied to its 2020 takeover of Mellanox, the Israeli networking company that powers data centers. The preliminary finding knocked Nvidia shares down about 2% in premarket trading.

The Mellanox Mess
The $7 billion acquisition was greenlit by China at the time, but only with conditions. Regulators now argue Nvidia didn’t stick to all the rules. Details on the exact violations remain vague, but the probe signals Beijing is tightening its grip on U.S. tech giants.

Trade Talks in the Crossfire
The announcement landed awkwardly — right as U.S. and Chinese officials met in Madrid to restart trade negotiations. Analysts warn the move could add fresh tension to already fragile relations.

Chip Wars Escalate
The probe is just one front. Over the weekend, China opened two more investigations into U.S. chips: one targeting alleged dumping and another hitting back at U.S. restrictions. Nvidia, meanwhile, has already been bruised — its H20 chip, designed to comply with U.S. export rules, was blocked from shipping to China earlier this year.

Huang’s $50 Billion Plea
Nvidia CEO Jensen Huang has been vocal, warning Washington that if U.S. firms can’t sell into China, domestic rivals like Huawei will fill the void. He estimates China’s AI market could hit $50 billion within three years, making it too big to ignore.

A Costly Compromise
That lobbying scored Nvidia a temporary reprieve: a deal with Washington last month allowed the company to resume chip sales to China — but only if it handed over 15% of that revenue to the U.S. government. Now, with Beijing’s probe underway, even that fragile compromise looks shaky.

The Bottom Line
​What started as a $7 billion acquisition has ballooned into a geopolitical storm. For Nvidia, the Mellanox deal is no longer just about servers — it’s about survival in the world’s most contested tech battleground.
