I am following the tech market and one thing that is becoming increasingly clear is that the biggest technology companies in the world remain concentrated in the US, but the story is more interesting than it seems. AI has accelerated all of this in a way no one expected.

At the top, you have Microsoft, Apple, Amazon, Alphabet, and Tesla dominating. But what caught my attention was Nvidia. This company grew so much that in 2025 it surpassed Apple and Microsoft in market value. In five years, the appreciation was 1,646% — truly absurd numbers. The folks who invested early must be very happy.

Now, what many people don’t realize is that the biggest technology companies in the world are not only American. Asia is also in the game with billions flowing between its companies. And here in Brazil? We also have our highlights.

Totvs was a standout in 2025 with partnerships in generative AI and integration with cloud ERP platforms. Then there’s Locaweb and Sinqia, which are also growing. They are nowhere near the size of the American giants, but the Brazilian tech sector is moving.

What’s happening is that artificial intelligence, automation, big data, and cloud computing are transforming everything. The biggest tech companies in the world are at the center of this revolution, and those who entered early are reaping the benefits.

If you’re thinking about investing in the sector, international options like Apple, Microsoft, and Nvidia continue to be the most solid. But it’s also worth keeping an eye on Brazilian companies like Totvs. The tech market remains one of the most promising, and in 2026, the trends that started in 2025 are only expected to intensify.
