Tesla Inc. (NASDAQ: TSLA) CEO Elon Musk has positioned the automaker as the leader in domestic manufacturing within the United States, citing a high percentage of American-made parts in its vehicles. This claim emerges against a backdrop of shifting trade policies under President Donald Trump’s administration, which has implemented tariffs on the auto industry.

Domestic Content Claims

On Saturday, podcast host Katie Miller shared a Wall Street Journal article on social media platform X highlighting Ford Motor Co. (NYSE: F) and General Motors Co. (NYSE: GM) efforts to boost domestic manufacturing. Miller noted that every Tesla sold in the United States is assembled in the country.

Responding to this observation, Musk expanded on Tesla’s manufacturing footprint. He stated that beyond assembly, the parts used in Tesla vehicles are “overwhelmingly made in America.”

On Sunday, Musk quoted a post by Wes Morill, lead engineer for the Cybertruck, to provide specific data points regarding domestic content. According to Morill, Tesla vehicles achieved an 84% total domestic content score. In contrast, Ford vehicles were reported to have 63% American parts.

Musk concluded that Tesla cars sold in America are the “most made in America of any cars.”

Tariff Impact on Competitors

The discussion coincides with comments from Howard Lutnick, Trump’s Commerce Secretary, who supported the administration’s tariffs on the auto industry. Lutnick stated that these measures are bringing “thousands” of jobs back to American auto manufacturing. He also endorsed Ford’s decision to shift production of some Lincoln vehicles away from China and into the U.S.

Ford CEO Jim Farley confirmed that the move to relocate production was a direct response to the tariffs. Farley noted that the Lincoln Nautilus SUV, currently imported from China, attracts a 52.5% tariff. Ford plans to begin U.S. production for these models starting in 2030.

What the Numbers Show

The disparity between Tesla’s 84% domestic content score and Ford’s 63% highlights a significant divergence in supply chain localization strategies. While both companies are responding to tariff pressures, Tesla’s existing infrastructure allows it to claim a substantially higher degree of domestic integration compared to traditional OEMs still reliant on imported components like the Lincoln Nautilus, which faces a steep 52.5% tariff rate.

Market Reaction

Tesla shares (TSLA) rose 0.43% to $343.73 during overnight trading.

Tesla Inc. (NASDAQ: TSLA) faces renewed scrutiny from investor Gary Black, who warned that enthusiasm for the company’s products and leadership is obscuring significant valuation concerns. In a post on X on August 16, 2026, Black highlighted that the stock’s current pricing metrics pose challenges for investors, regardless of brand loyalty.

Valuation Metrics

Black pointed to specific forward-looking estimates to illustrate the disparity between Tesla’s price and its growth prospects. He noted a projected price-to-earnings (P/E) ratio of 200x for 2026, alongside an expected long-term growth rate of 35%. These figures result in a price/earnings-to-growth (PEG) ratio of 5.7x.

This valuation multiple stands in stark contrast to broader market peers. Black compared Tesla’s PEG ratio to the average of 2.4x for the Magnificent 8 stocks, suggesting Tesla is priced at a significant premium relative to its expected earnings growth.

What the Numbers Show

The divergence between Tesla’s PEG ratio and the Magnificent 8 average indicates that the market is pricing in nearly double the premium per unit of growth compared to its peer group. With a PEG of 5.7x versus a peer average of 2.4x, Tesla’s valuation relies heavily on the assumption that its 35% growth rate will be sustained at levels far exceeding those required to justify the current share price relative to earnings.

Strategic Concerns

Black’s critique extends beyond valuation to operational strategy. He previously argued that Tesla cannot replicate Apple Inc.’s (NASDAQ: AAPL) marketing effectiveness by relying solely on word-of-mouth and CEO Elon Musk’s social media presence. Black suggested that professional marketing investment is necessary for expansion into autonomous driving and robotics.

Additionally, Black expressed skepticism regarding Tesla’s self-driving ambitions, noting that investors are losing faith in the company’s ability to scale autonomy using Musk’s vision-only approach. He also criticized the "cult" mentality among some shareholders, warning that attachment to the stock has led to underperformance compared to a basket of Nasdaq-100 names over the past five years. Black had previously valued Tesla at $312.
