Mercedes-Benz, the company synonymous with German engineering and leather-scented luxury, might get kicked out of the American market. Not because of tariffs, not because of emissions scandals, but because of who owns its stock.

A bipartisan Senate bill introduced in April 2026 by Senators Elissa Slotkin (D-Mich.) and Bernie Moreno (R-Ohio) would prohibit the sale of connected vehicles in the US by any automaker where more than 15% of ownership is held by Chinese entities. Mercedes-Benz Group AG has roughly 20% of its ownership linked to Chinese stakeholders. In English: Mercedes is over the line, and the consequences could be enormous.

The ownership problem Mercedes can’t easily fix

Two major Chinese stakeholders put Mercedes on the wrong side of the proposed 15% threshold. BAIC, a Chinese state-owned automaker, holds approximately 10% of Mercedes-Benz Group. Li Shufu, the founder of Geely (the Chinese company that also owns Volvo Cars), holds another roughly 10%. Combined, that’s about 20% Chinese ownership.

Mercedes is now actively lobbying Congress to raise the ownership ceiling from 15% to 25%. The argument is straightforward: these are passive investments, not operational control. BAIC and Li Shufu aren’t designing Mercedes vehicles or accessing customer data. They’re shareholders collecting dividends.

The Senate Commerce Committee is set to review the bill during the week of July 21, 2026, making the next few weeks a critical window for Mercedes’ lobbying operation.

Why connected vehicles are the real target

This bill isn’t about who makes the best sedan. It’s about data, surveillance, and the digital infrastructure embedded in modern cars.

Connected vehicles collect vast amounts of data. Location tracking, driving patterns, voice commands, camera feeds. The concern on Capitol Hill is that Chinese-linked ownership could theoretically provide a pathway for that data to flow to Beijing.

The bill follows similar proposals in the House, including the Motor Vehicle Modernization Act of 2026, which contains comparable 15% ownership restrictions. Mercedes isn’t alone in the crosshairs either. Volvo Cars, majority-owned by Geely, has been identified as potentially affected by the proposed ownership limits.

The broader US-China decoupling in autos

The logic follows a familiar template: connected devices with Chinese ties represent national security risks. It’s the same reasoning that led to restrictions on Huawei and TikTok, now applied to vehicles that can record conversations, track locations, and connect to home networks.

What this means for investors

The immediate market impact depends entirely on what happens in committee during the week of July 21. If the bill advances with the 15% threshold intact, Mercedes-Benz shares could face meaningful selling pressure as investors price in the risk of losing US market access.

The ripple effects extend beyond Mercedes. Any non-Chinese automaker with significant Chinese investment will need to reassess its shareholder composition.

Traders should watch the Senate Commerce Committee markup closely. If Mercedes’ lobbying succeeds and the threshold moves to 25%, the company clears the bar. If the 15% number holds, the playbook shifts to watching whether Mercedes can convince its Chinese shareholders to reduce their positions.

Volvo Cars investors face an even starker calculus, given Geely’s majority ownership stake. For that company, no amount of threshold adjustment would help.
