What drove the stock market last week — before and after SpaceX's historic IPO

SpaceX’s debut was a major success, with the stock closing up 19% at nearly $161 and valuing the company at more than $2.1 trillion after raising $75 billion in the largest IPO ever. The strong launch eased market concerns about mega-IPO absorption and helped lift equities, with the S&P 500 up 0.5% and the Nasdaq up 0.3% on Friday. The article also highlighted AI-related capital spending, hotter May CPI data, and expectations that the Fed will hold rates steady at its June 17 meeting.

Analysis

The key market takeaway is not the IPO itself, but the signal it sends about equity absorption capacity after a period of heavy supply anxiety. A clean debut in the largest float-ever reduces the near-term overhang on cyclicals and financials that were trimmed to fund cash, but it also re-prices the “mega-cap AI capex” ecosystem: if public markets can digest this kind of issuance, the bottleneck shifts from financing availability to power, optics, and networking throughput. That favors infrastructure enablers with contracted demand visibility more than the headline AI platforms.

The most interesting second-order winner is the networking/fiber stack. Large AI buildouts are becoming constrained by energy efficiency and deployment speed, which tends to pull forward orders for optical components, high-speed interconnect, and data-center electrical gear. That is supportive for GLW, AMZN-related capex, and arguably BAC/GS on the financing side, but the banks also face a flatter near-term IPO fee curve if these late-stage names price with ample enthusiasm rather than scarcity premiums. On the flip side, ORCL’s selloff suggests the market is starting to punish funding raises unless they come with clearer utilization proof, so the bar for AI capex announcements has risen.

Inflation and policy remain the macro check on this risk-on setup. If the current inflation prints are transitory and tied to energy, the market can keep leaning into AI and IPO supply; if follow-through data broadens beyond oil, duration-sensitive winners like NDAQ and high-multiple tech can quickly lose momentum. The main near-term risk is a reversal in sentiment if the next Fed communication sounds more hawkish than the market expects, because the current rally is built on the assumption that financing conditions stay benign even as capital intensity rises.

Key Decisions for Investors

• Add to GLW on weakness over the next 1-3 weeks; risk/reward is attractive because optical demand is now tied to multi-year AI capex rather than one-quarter order flow, with downside limited by recurring hyperscaler demand.
• Maintain/expand long INTC vs short ORCL as a relative-value pair for the next 1-2 months; the setup favors operationally improving hardware names over companies being penalized for funding intensity without immediate proof of payback.
• Initiate a tactical long BAC / GS basket into any post-Fed dip, but size modestly; IPO supply digestion can support fees and trading activity, yet hawkish policy language is the main near-term risk to financial beta.
• Fade AAPL strength via put spreads or a small short against NVDA over 2-6 weeks; the market is rewarding monetizable AI infrastructure more than consumer AI branding, and Apple’s AI narrative looks less proven relative to capex beneficiaries.
• Keep a core long AMZN and pair it against ORCL for 1-3 months; AMZN captures the infrastructure demand directly, while ORCL is more exposed to the market’s current skepticism toward capex-led growth stories.
