The AI rally has gotten ahead of itself
Uma corrida impulsionada pela inteligência artificial chegou a um momento de pausa reflexiva: a Nvidia, recém-coroada a empresa mais valiosa do mundo, recuou 3,5% e arrastou futuros globais para baixo numa sexta-feira marcada pelo vencimento de US$ 5,5 trilhões em derivativos. Os mercados, que por meses navegaram numa maré de otimismo tecnológico, agora aguardam dados econômicos que dirão se a expansão que justificou essas alturas ainda está de pé — ou se o entusiasmo correu mais rápido do que a realidade.
- A Nvidia caiu 3,5% após tornar-se a empresa mais valiosa do mundo, interrompendo abruptamente o ímpeto da alta impulsionada pela IA.
- O chamado 'triple witching' — vencimento simultâneo de US$ 5,5 trilhões em contratos de derivativos — obriga traders a reposicionar apostas, injetando volatilidade num momento já delicado.
- Bolsas na Ásia fecharam no vermelho, com Hong Kong, Coreia do Sul e Taiwan sentindo o peso da fraqueza do Nasdaq, enquanto o iene japonês acumula seis dias de queda e levanta o espectro de intervenção oficial.
- Na Europa, o Stoxx 600 abriu em baixa e a Carlsberg despencou 9% após a Britvic rejeitar duas ofertas de aquisição, chamando o lance de subavaliação significativa.
- Os dados de PMI dos EUA e da Europa, esperados ao longo do dia, serão o teste decisivo: confirmam expansão econômica ou validam os temores de que as valorizações foram longe demais?
A corrida da inteligência artificial que sustentou os mercados globais por meses deu sinais de cansaço numa sexta-feira de contornos delicados. Os futuros americanos operavam levemente no negativo após um fechamento misto em Wall Street: o Dow Jones superou 5.500 pontos pelo melhor dia do mês, mas o Nasdaq terminou em queda, puxado pela Nvidia — a fabricante de chips que acabara de se tornar a empresa mais valiosa do mundo e que recuou cerca de 3,5%, interrompendo uma escalada que parecia imparável.
O momento coincide com o chamado triple witching, evento trimestral em que opções e futuros vinculados a ações e índices vencem simultaneamente. Segundo a plataforma SpotGamma, cerca de US$ 5,5 trilhões em contratos chegam ao vencimento nesta sexta, forçando traders a rolar posições ou abrir novas apostas — um processo mecânico que pode amplificar movimentos em qualquer direção. Jamie Cox, da Harris Financial Group, resumiu a incerteza ao CNBC: há sinais de mercado superaquecido, mas ainda não está claro se o teto da corrida da IA foi atingido.
Na Ásia, as bolsas fecharam em baixa, com as praças de tecnologia em Hong Kong, Coreia do Sul e Taiwan refletindo a fraqueza do Nasdaq. O iene japonês acumulou seis dias de queda, alimentando especulações sobre intervenção cambial. Na Europa, o Stoxx 600 abriu no vermelho, com bancos e construção liderando as perdas. Um episódio corporativo chamou atenção: a Carlsberg despencou 9% após a Britvic rejeitar duas ofertas de aquisição da gigante dinamarquesa, alegando subavaliação — as ações da Britvic dispararam mais de 11%.
Nas commodities, o petróleo Brent recuou para US$ 85,62 e o WTI para US$ 81,22, pressionados pela perspectiva de juros elevados. O Bitcoin caiu 1,3%, para US$ 64.109. O dia se encaminha para um teste: os índices PMI dos EUA e da Europa dirão se a expansão econômica que sustentou o otimismo dos mercados ainda está em curso — ou se chegou a hora de uma consolidação mais prolongada.
The artificial intelligence rally that has powered global markets higher for months is showing signs of fatigue. On Friday morning, stock futures across the United States were trading slightly lower, a pullback that follows a mixed close on Wall Street the day before. The Dow Jones had reached its best day of the month, crossing above 5,500 points for the first time, but the Nasdaq Composite finished in the red despite hitting an intraday record. The culprit was Nvidia, the chip manufacturer that just this week became the world's most valuable company. The stock fell roughly 3.5 percent, interrupting what had been a relentless upward march.
This pullback arrives as traders brace for what the market calls triple witching—a quarterly event when stock-linked derivatives, index options, and futures contracts all expire on the same day. According to SpotGamma, an options analytics platform, roughly 5.5 trillion dollars in contracts are set to expire on Friday. When that much notional value comes due at once, traders must either roll their existing positions into new ones or establish fresh bets, and the mechanical nature of that process can introduce volatility into otherwise calm markets. The timing is delicate: the AI-driven rally has lifted valuations to levels that some strategists are beginning to question.
Jamie Cox, a managing partner at Harris Financial Group, captured the uncertainty in a comment to CNBC. While some signals of an overheated market are appearing, he said, it remains unclear whether the artificial intelligence rally has truly hit its ceiling or whether it can sustain its meteoric rise. The market is waiting for clarity, and that clarity may come from economic data released on Friday. The United States is scheduled to publish manufacturing and services purchasing managers' indices, with expectations of 51 and 53.7 respectively—figures that would suggest both sectors are expanding. Housing sales data for May will also be released.
Across Asia, stock markets closed lower on Friday as the Nasdaq's weakness rippled through technology-heavy exchanges in Hong Kong, South Korea, and Taiwan. China's mainland markets also fell, dragged down by consumer-related stocks. Japan's purchasing managers' index for manufacturing ticked upward to 50.5 from 49.9, suggesting industrial activity there is expanding, though the composite index fell from 52.6 to 50. The Japanese yen remained in focus after six consecutive days of decline raised the specter of official intervention to support the currency.
European markets opened lower, following the American lead and watching the yen's weakness with concern. The Stoxx 600 index fell, with banking and construction stocks leading the declines. One notable corporate drama unfolded when Carlsberg's stock plummeted 9 percent after the British soft-drink maker Britvic rejected two unsolicited acquisition offers from the Danish beverage giant, saying the latest bid of 1,250 pence per share significantly undervalued the company. Britvic's shares surged more than 11 percent on the news of the rejection.
Commodity markets reflected the broader caution. Brent crude oil fell 0.11 percent to $85.62 a barrel, and West Texas Intermediate dropped 0.09 percent to $81.22, both pressured by expectations that interest rates will remain elevated across Asia and the United States. Iron ore traded on the Dalian exchange fell 0.36 percent. Bitcoin, which has often moved in tandem with technology stocks and risk appetite more broadly, declined 1.3 percent to $64,109.60.
The day ahead will test whether the artificial intelligence boom has room to run or whether markets have priced in gains that cannot be sustained. The purchasing managers' indices will offer a window into whether economic expansion is continuing at the pace markets have been assuming. With 5.5 trillion dollars in derivatives expiring, any surprise in those numbers could amplify moves in either direction. For now, the momentum that carried stocks higher has stalled, and traders are waiting to see whether it resumes or whether a period of consolidation has begun.

A Conversa do Hearth Outra perspectiva sobre a história
Why does it matter that Nvidia fell 3.5 percent when the Dow hit a record?
Because Nvidia isn't just another stock—it became the world's most valuable company this week, and the entire AI rally has been built on the idea that these chip makers will power the next generation of computing. When the most valuable company stumbles, it signals that maybe the rally has gotten ahead of itself.
What's triple witching, and why should anyone care?
It's when three types of derivatives all expire at once—options, index options, and futures. Five and a half trillion dollars worth are expiring Friday. That forces traders to either close positions or roll them forward, and all that mechanical buying and selling can create volatility that has nothing to do with fundamentals.
So the market is overheated?
That's the question. Some signals suggest it might be—valuations are stretched, especially in technology. But Jamie Cox from Harris Financial Group said it's not clear yet whether the AI rally has truly hit its limit or if it can keep climbing. The market is genuinely uncertain.
What would change the picture?
The purchasing managers' indices coming out today. If manufacturing and services are both expanding as expected, that justifies the valuations. If they disappoint, it suggests the economy isn't as strong as stock prices are assuming, and you could see a sharper pullback.
Why are Asian and European markets falling too?
Because when the Nasdaq stumbles, it ripples outward. Technology stocks in Hong Kong, Seoul, and Taipei all fell. And Europe is watching the yen weaken, which creates its own set of concerns about currency intervention and capital flows.
Is this the beginning of something bigger, or just a pause?
That's what nobody knows yet. It could be a healthy correction after a long run, or it could be the first crack in a structure that's been built too fast. The data today will help answer that.
