U.S. equities closed higher Friday, capping a week of broad gains—SPY rose 0.72% to $747.03 and QQQ added 0.65% to $687.99. The 524 companies in the AI‑infrastructure universe underperformed with an average move of just 0.36%, 304 advancing and 216 declining, leaving the group 36 basis points behind the S&P. Networking stocks led at +2.24%, while power‑generation names lagged at –1.29%. IESC surged 30.3% to headline the gainers; HUN was the session’s weakest link, falling 19.1%.

Westinghouse confidentially submits an IPO filing. BEP ([Brookfield Renewable Partners)](/company/BEP) and CCJ (Cameco Corporation) jointly announced late this week that Westinghouse Electric Company has confidentially filed a draft registration statement for a proposed public offering. Brookfield Renewable owns a controlling stake in Westinghouse, a leading provider of nuclear reactor technology and services. The step places a concrete marker behind the nuclear industry’s push to supply round‑the‑clock clean power, an increasingly critical resource for hyperscale data‑center operators who are locking in long‑term power purchase agreements with nuclear generators.

Everus Construction to acquire modular‑solutions provider. ECG (Everus Construction Group) disclosed an agreement to acquire Epsilon Industries, a specialist in off‑site modular construction. Everus aims to shorten field‑installation timelines—a persistent bottleneck for data‑center projects where speed to operational power is paramount. The deal could expand Everus’s ability to deliver pre‑fabricated mechanical and electrical assemblies directly to job sites, reducing on‑site labor demands.

Cerebras faces investor investigation. CBRS (Cerebras Systems Inc.) is the subject of a securities‑law investigation, according to a notice from Kaplan Fox, focused on potential disclosure violations. The wafer‑scale AI processor maker has not commented. While the investigation is at an early stage, it adds uncertainty for a company that is working to scale its CS‑3 systems alongside traditional GPU‑based clusters in AI training environments.

Tuesday, August 4: WDC (Western Digital) reports fiscal fourth‑quarter results (EPS estimate $3.30). NAND‑flash supply‑demand and hyperscaler storage orders are the key AI‑infrastructure vectors. Commentary on enterprise SSD pricing and nearline capacity additions will be read as a forward indicator for cloud capex intensity. Also reporting Tuesday: ALAB (Astera Labs) (EPS estimate $0.69). Its intelligent connectivity platform is a read‑through for PCIe/CXL retimer attach rates in GPU‑heavy clusters, making the print pertinent for AI‑server architecture trends. CIFR (Cipher Mining) (loss estimate $0.24) provides an update on its pivot from bitcoin mining toward HPC co‑location services.

Wednesday, August 5: VECO (Veeco Instruments) (EPS estimate $0.26) and TLN (Talen Energy) (EPS estimate $3.12) both report. Veeco’s ion‑beam and MOCVD tools feed compound‑semiconductor and advanced‑packaging lines that underpin AI chip production; the order book will be scrutinized for fab‑expansion momentum. Talen’s nuclear generation fleet and its ability to ink long‑term data‑center power contracts will be parsed as the direct‑connect model becomes more mainstream. Also on Wednesday: TTMI (TTM Technologies) (EPS estimate $0.89) offers a window into high‑reliability PCB demand for networking and compute.

Thursday, August 6: DDOG (Datadog) delivers second‑quarter results (EPS estimate $0.58). Datadog’s cloud‑monitoring and AI‑observability revenue is a proxy for the health of AI‑native workloads running on major public clouds; a solid print would suggest enterprise AI adoption is translating into real consumption growth.
