US Stocks Edge Higher as Investors Await July Inflation Data and CoreWeave Surges 17%

US stocks edged cautiously higher on August 12 as investors awaited the release of the July consumer price index (CPI), a reading expected to weigh heavily on the Federal Reserve's decision at its September meeting on whether to cut rates further. CRWV provided one of the session's bigger individual moves: shares jumped in early trading, at one point rising as much as 20%, after the AI cloud provider posted second-quarter revenue of roughly $2.6 billion, more than double the year-ago period and above Wall Street's consensus estimate [doc2, doc4].

The CoreWeave print mattered beyond the stock itself. The company cited surging demand for AI infrastructure from hyperscale customers and reported a revenue backlog of roughly $104 billion, reinforcing the market's read that AI-driven data center spending remains a durable growth engine even as investors grow more sensitive to valuations in the space [doc2, doc4]. That combination of a smaller-than-expected loss and a much larger backlog helped calm concerns that had built up ahead of the report.

The broader market's muted, wait-and-see tone reflects how central the inflation data has become to rate expectations. A softer-than-expected CPI print could reinforce the case for continued Fed easing and support the rally in AI-linked names, while a hotter reading could complicate that path and inject volatility into a market that has leaned on rate-cut expectations for support .

What to watch: the CPI release itself, any shift in Fed rate-cut odds that follows, and whether other AI infrastructure and hyperscaler names see a similar lift to CoreWeave's, which would suggest the market is rewarding capacity and demand signals over near-term profitability in the sector.
