US equity futures rose 0.5% on Tuesday, trimming losses from the previous session as chip producers rebounded and Treasury yields softened. Contracts for the S&P 500, Dow and Nasdaq 100 each gained 0.5%. AI-infrastructure companies recovered from aggressive losses as investors weighed uncertainty over the sector, including the prospect of massive IPOs (initial public offerings) by hyperscalers such as Anthropic and OpenAI against doubts that near-term AI demand can justify the scale of capital expenditure. Nvidia edged higher ahead of its earnings tomorrow. Broader sectors also advanced as long-term Treasuries recovered from recent selloffs. US Secretary Treasury Bessent threatened sanctions against banks and companies that intermediate trade with Iran, while energy prices eased after Iran responded to the threats. GE Vernova and Veritiv gained more than 2%.
