Morning recap: The AI trade delivered

The morning session played out almost exactly as the pre-market briefs suggested it would. Cisco Systems (CSCO) was the session's single most dramatic mover, posting its largest single-day gain since 2011 after reporting a strong sales forecast and unveiling a restructuring plan centered on AI infrastructure. The stock's reaction confirmed what the morning setup implied: investors had been underpricing Cisco's ability to participate in the AI buildout, and the earnings report forced a rapid reassessment.

The Dow Jones Industrial Average revisited the 50,000 level, with CSCO and Nvidia (NVDA) among the primary contributors. The S&P 500 and Nasdaq both traded higher, broadly in line with the bullish pre-market tone.

The one potential disruptor — April's CPI reading of 3.8% year-over-year, the highest since 2023 — did not derail the rally. Markets absorbed the inflation data without a sharp selloff, choosing instead to focus on the AI spending narrative that dominated headlines from the open.

The shift: Policy approval changes the Nvidia calculus

The morning's most consequential development was not a stock move but a regulatory one. The U.S. government approved approximately ten Chinese companies — including Alibaba — to purchase Nvidia's H200 AI chips, ending a period of restriction that had effectively closed China as a market for Nvidia's most advanced processors.

This is a meaningful policy shift, not a minor administrative update. The H200 is Nvidia's high-performance AI training chip, and China represents one of the largest potential markets for AI compute hardware. CEO Jensen Huang has been publicly advocating for expanded export access, and the approval arrived in the context of a Trump-Xi summit — giving it both commercial and diplomatic weight.

European semiconductor stocks moved higher on the news. NVDA itself is benefiting from the dual tailwind of the export approval and the broader AI spending cycle. The stock's six-session winning streak heading into this week now has an additional fundamental catalyst behind it.

The separate Terafab announcement from Elon Musk — a $119 billion joint venture targeting one terawatt of annual AI compute capacity — added to the sector's momentum. Tesla (TSLA) and Intel (INTC) are the named tickers associated with the venture, though the structure remains a joint venture with partners not fully disclosed in available reporting. At $119 billion, Terafab would be one of the largest single industrial commitments in semiconductor history, and the announcement reinforced the session's central narrative: that AI infrastructure spending is accelerating, not plateauing.

Cerebras, the AI chip startup and Nvidia competitor, also completed its U.S. IPO debut, raising $5.55 billion — one of the larger tech listings in recent memory. Alphabet (GOOGL) is simultaneously selling $17 billion in bonds to fund its own AI capital expenditure, part of what analysts have described as a $300 billion debt-and-equity cycle running in parallel across global markets.

The inflation counterweight holds but doesn't go away

April's 3.8% CPI print is the session's unresolved tension. Gasoline prices drove much of the increase, which offers some comfort — energy is excluded from core inflation measures and tends to be volatile. But the headline number is the highest since 2023, and it lands at a moment when the Federal Reserve had been inching toward a more accommodative posture.

The market's calm reaction to the data is partly explained by the AI rally providing an offsetting tailwind. But the inflation print is not a one-day story. It will shape the Fed's posture at its next meeting and is likely to keep Treasury yields elevated. Rate-cut expectations that had been drifting earlier in the year now face a harder path.

One analyst framing circulating this morning described the situation as the Fed's worst-case scenario: inflation moving higher while growth uncertainty persists. That framing may be too stark — a gasoline-driven spike is not the same as broad-based price acceleration — but the directional signal is clear enough that it cannot be dismissed.

Afternoon setup: What to watch into the close

The session's narrative is holding rather than shifting. The AI trade has momentum across equities, IPOs, and credit markets simultaneously, and there is no obvious catalyst in the afternoon session that would reverse it. But several dynamics are worth monitoring.

NVDA remains the most closely watched name into the close. The H200 export approval is a genuine fundamental development, not just sentiment, and the stock's move from here will reflect how much of that opportunity traders believe is already priced in. Nvidia is scheduled to report earnings on May 20 — that event is now the most important near-term catalyst on the calendar, with analysts projecting revenue growth that could push the company's market capitalization toward $8 trillion.

Any further headlines from the Trump-Xi summit on semiconductor trade policy could move the sector again before the close. The diplomatic backdrop has been a consistent tailwind today, and additional specifics — on TSLA's Full Self-Driving approval in China, for instance, or further chip export details — would have immediate price implications.

The CPI data will continue to weigh on fixed income. Watch whether Treasury yields drift higher into the afternoon as bond traders process the inflation print more fully. A sustained move up in yields would be the clearest sign that the macro counterweight is beginning to push back against the equity rally.

Finally, the Cerebras IPO pricing and early trading will be a read on how deep institutional demand for AI hardware names actually runs. A strong debut would extend the day's bullish tone. A muted one would be worth noting — not as a signal that the AI trade is over, but as a data point on where investor appetite has its limits.
