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.

This amount represents a balance that is +60% higher than what was invested a year ago and still exceeds analysts’ estimates on Wall Street by US$ 50 billion.

The central point of investor concern lies in the return capacity of these billion-dollar investments aimed at building infrastructure to support artificial intelligence tools.

Amazon is not alone in this movement. Alongside Google (GOGL34), Microsoft (MSFT34), and Meta (M1TA34), the projection is that US$ 700 billion will be allocated to artificial intelligence spending this year alone, which increases pressure on the market.

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.
