With US$ 700 Billion Projected in Investments, Artificial Intelligence Increases Volatility on Wall Street, Decreases Amazon’s Market Value, and Influences Performance of Brazilian Companies Listed in the United States

While Brazil is still experiencing the rhythm of Carnival 2026 and B3 remained closed until Ash Wednesday at 1 PM, artificial intelligence returned to the spotlight in the US stock markets, causing relevant fluctuations this Tuesday (17).

Volatility strengthened amid doubts about the viability of heavy investments in AI, especially among the technology giants.

Amazon (AMZO34) is one of the most emblematic examples of this movement. Far beyond online retail, the company strongly focuses on cloud data storage and announced plans to invest US$ 200 billion in 2026, primarily directed at AI-related projects.

Artificial Intelligence Causes Billion-Dollar Loss at Amazon

Since February 2, Amazon has accumulated a market value loss of around US$ 450 billion.

On the trading day this Tuesday (17), the stock dropped as much as -1.4%, reaching a low of US$ 196 on Nasdaq.

By the end of the day, however, there was a rebound: the shares rose +1.19%, closing the session at US$ 201.15.

The movement reflected a day of strong instability on Wall Street. In the final minutes of trading, the main indices managed to pull back from the red and ended nearly flat.

It is worth noting that the previous day, the financial markets in the US were closed due to the national holiday for Presidents’ Day.

Dow Jones: +0.07% / 49,533.19 points
S&P 500: +0.10% / 6,843.22 points
Nasdaq-100: +0.14% / 22,578.38 points

Brazilian Investments Feel the Impact in the US

Even with B3 closed due to Carnival, it was possible to track the performance of Brazilian companies listed in the United States.

The iShares MSCI Brazil ETF (EWZ), which serves as a sort of Ibovespa in dollars, closed the day down -0.84%, priced at US$ 37.74 per share.

Vale’s shares (VALE3), traded on the New York Stock Exchange under the ticker VALE, fell -4.50%, closing at US$ 15.90.

The market is closely monitoring the psychological barrier of iron ore in China above US$ 100 per ton.

Meanwhile, Petrobras (PETR4), traded overseas as PBR, dropped -1.12%, ending the session at US$ 15.02. Brent crude also registered a decline of -0.89% on the London Stock Exchange, priced at US$ 62.33 per barrel, amid diplomatic negotiations between the US and Iran.

Other Brazilian companies also experienced significant fluctuations on this February 17, 2026. Vale (VALE): -4.50% / US$ 15.90 per share / Mining.

Suzano (SUZ): -1.88% / US$ 10.97 per share / Paper & Cellulose. Gerdau (GGB): -1.70% / US$ 4.05 per share / Steel. Petrobras (PBR): -1.12% / US$ 15.02 / Oil.

Nubank (NU): 0.00% / US$ 16.82 per share / Financial. Itaú (ITUB): +0.11% / US$ 9.17 per share / Banks. Embraer (EMBJ): +0.66% / US$ 71.51 per share / Aviation.

The scenario indicates that even amid the Brazilian holiday, the impacts of artificial intelligence and large investments in technological infrastructure continue to influence the sentiment of global investors and the performance of Brazil-related assets abroad.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

A surreal road in southern Brazil cuts through the Serra do Corvo Branco, revealing mountains that resemble pyramids, cliffs used in commercials, and a Santa Catarina village marked by a sad history before the access was fully paved.

Webb found a cradle of planets 5,550 light-years away where water almost disappears, and the disk around the star XUE 10 has CO₂ in regions where rocky worlds like Earth should be born, revealing a planetary chemistry very different from that which formed our Solar System.

Couple transforms abandoned land in Portugal, moves a 6-ton tiny house, hides a container on the slope, and builds a 50 m² deck in two days while advancing on the main house surrounded by glass and nature.

Giant trucks with no one in the cabin have already moved more than 8.6 billion tons of rock and ore around the world, equivalent to more than a thousand Great Pyramids, all without a single recorded injury.
