Wall Street Mixed as Rate Hike Fears Offset Nvidia Rally; SpaceX Sinks on AI Cost Surge

The Quick Take

• The S&P 500 and Nasdaq edged lower despite Nvidia's rally, as renewed rate hike concerns weighed on sentiment
• SpaceX shares fell after reports of higher-than-expected AI-related capital expenditures and a pending share unlock
• The session reflects a tug-of-war between AI equity optimism and monetary policy uncertainty in US markets

US equity markets closed mixed in the latest session, with the S&P 500 and Nasdaq Composite edging lower even as Nvidia extended its recent momentum. The divergence highlights a key tension in 2026 markets: individual AI-beneficiary names are posting strong returns while rate-sensitive valuations across the broader index face pressure from persistent inflation and market speculation about additional Federal Reserve tightening. SpaceX, though privately held, saw its secondary-market shares fall after reports emerged of elevated AI-infrastructure spending and an impending unlock of employee shares — adding a supply overhang concern to the cost-escalation narrative.

The market's mixed close is meaningful for portfolio positioning in India and across Asia, where institutional investors closely track Wall Street sentiment as a proxy for global risk appetite. A sustained period of US rate hike fears could trigger FII outflows from Indian equities, widening the rupee-dollar spread and weighing on emerging market bond yields. Conversely, Nvidia's continued rally amid broader weakness validates the AI investment thesis — a signal that may encourage incremental flows into India-listed technology infrastructure and semiconductor supply-chain names despite the prevailing macro headwinds.

The key variable to watch is the next US Consumer Price Index print, which will determine whether the Fed's data-dependent stance leans toward another rate hike or a prolonged pause. On the AI capex side, SpaceX's reported AI spending is part of a broader trend of private space-tech investments in GPU clusters and inference infrastructure — any guidance from major cloud companies on AI capex trajectories will inform whether the AI equity rally has fundamental earnings support. Watch also the shape of the US Treasury yield curve for leading signals on where rate expectations are heading.
