The S&P 500 (SNPINDEX:^GSPC) added 0.15% to close at 6,977, while the Nasdaq Composite (NASDAQINDEX:^IXIC) rose 0.26% to finish at 23,734. Within cloud infrastructure services, industry peers Cloudflare (NYSE:NET) and DigitalOcean (NYSE:DOCN) gained 1.96% and 3.97%, respectively, as investors tracked AI-related network demand and evolving cloud pricing power.

What this means for investors

CoreWeave CEO Michael Intrator made headlines after he and another executive spoke on a podcast addressing concerns over the useful life span of graphics processing units (GPUs) the company has accumulated.

That helped push investors back into the stock with analysts backing CoreWeave as it plans to add Nvidia's (NASDAQ:NVDA) next-generation Rubin AI architecture to its infrastructure. Nvidia holds a meaningful minority stake in CoreWeave, which also gives investors confidence in its future growth.
