Visa

Visa is at the top of the list in terms of net profitability. Its net profit margin stands at 52.9%. The American company holds a unique position in the global payment infrastructure, acting as an intermediary in billions of card transactions. Visa earns a small fee from each transaction, but with $13.2 trillion in processed payments in 2024, those fractions of a percent add up to enormous profits. This level of market concentration has already attracted the attention of antitrust authorities in the US, EU, and other countries.

Nvidia

In second place is American tech giant Nvidia, with a net profit margin of 48.85%. The company not only maintains its leadership in AI chip development, but also became the first in history to surpass a $4 trillion market capitalization. Nvidia operates under a fabless model — it designs chips but outsources their manufacturing, allowing it to keep costs low. The explosive demand for AI technology has turned its flagship GPUs into a critical resource for data centers worldwide.

TSMC

Taiwanese semiconductor manufacturer TSMC ranks third, with a net profit margin of 39.4%. The world’s largest contract chipmaker produces semiconductors for tech giants like Apple, AMD, and Nvidia. Despite a dip in profits during the 2023–2024 fiscal year due to a temporary demand slowdown, TSMC bounced back rapidly. AI chip sales fueled a nearly 68% year-over-year increase in net profit. Its success is driven by technological leadership in 3-nanometer chip production.

Broadcom

Fourth is Broadcom, an American company with a net profit margin of 39.31%. In the 2023–2024 fiscal year, its net profit reached $14.08 billion, up 22.5% from the previous period. Growth was driven by AI-related product sales and an expanded client base in the cloud and telecom sectors. Despite temporary cost pressures linked to its VMware acquisition, the deal is already paying off, pushing revenues to record highs.

UBS

Fifth is Swiss banking group UBS, with a net profit margin of 39.09%. In the 2023–2024 fiscal year, UBS posted a staggering 265% increase in net profit, reaching $27.85 billion. Favorable market conditions and the strategic acquisition of longtime rival Credit Suisse fueled this surge. The deal significantly strengthened UBS's position in global banking, although profit later declined due to integration costs and a tougher market environment.
