US stocks opened higher on Monday, with technology shares leading gains after Anthropic publicly filed for its initial public offering. The Dow Jones Industrial Average rose 212 points, or 0.4%, while the S&P 500 gained 0.3% and the Nasdaq Composite advanced 0.3%.
The positive start follows two consecutive weekly declines for the S&P 500 and Nasdaq Composite, with Friday's session ending all three major indexes lower.
Anthropic's IPO filing lifts market sentiment
Anthropic's S-1 registration statement, filed Monday, provides investors with a detailed look at the AI company's financials ahead of its debut under the ticker ANT. The company reported $16.3 billion in revenue for the six months ended June, a significant jump from the $4.6 billion generated in all of 2025. However, it also disclosed a loss of $80.7 billion for the first half of 2026.
The filing has intensified scrutiny of Anthropic's financial performance as investors assess the prospects of one of the AI industry's most prominent players. Other major tech stocks also moved higher, with Nvidia up 1.9%, Micron jumping 2%, Intel rising 1%, and Advanced Micro Devices climbing 0.73%.
Oil retreats as diplomatic efforts offer relief
Crude prices fell over 1% on Monday as renewed diplomatic efforts to ease US-Iran tensions provided some relief after last week's rally. Brent crude dropped 1% to $115.42 a barrel, while US West Texas Intermediate fell 1.72% to $101.45. Brent had gained about 6% the previous week following attacks on Saudi Arabia that heightened supply concerns.
Qatari mediators traveled to Tehran on Sunday to help reduce tensions with Washington, prompting traders to pare back some of the risk premium on oil. However, the security situation remains unsettled, with the Iran-aligned Houthis claiming attacks on Saudi airport and oil facilities over the weekend, and Saudi authorities reporting intercepting additional missiles and drones.
Musk warns of neocloud failures, Brazilian stocks slide
Shares of major neocloud companies CoreWeave, Nebius, and IREN fell in premarket trading after Elon Musk warned that more than 200 companies in the sector could face failures and consolidation as financing becomes harder to obtain. In a post on X on Sunday, Musk said, "As of the past few weeks, debt markets have almost entirely shut off access to money for any company that doesn’t have substantial revenue independent of AI data centers." He added, "That means the 200+ neoclouds are going to see guppy-level death and consolidation. Some will make it through, but not many."
IREN shares fell roughly 2%, CoreWeave dropped around 2.2%, and Nebius declined more than 4.4%.
US-listed Brazilian stocks also came under pressure after Luiz Inácio Lula da Silva won Brazil's presidential election. Petrobras plunged 16% in early trading, Itaú Unibanco fell 21%, and brewer Ambev dropped 12%. Mining company Vale declined 1.72%, while aircraft manufacturer Embraer lost roughly 3%.
