S&P 500 Seven-Day Win Streak Ends as CPI Jumps to 3.4% — Amazon Rallies on Jassy AI Letter, Molotov Cocktail Hurled at Altman Home

Georgi Kuzmanov Senior Equity Analyst & Founder

The S&P 500’s best win streak since October came to a quiet end on Friday. The benchmark index dipped 7.77 points to close at 6,816.89 (−0.11%), weighed down by a hotter-than-expected March CPI print that pushed headline inflation to 3.4% year-over-year — the highest reading since the ceasefire energy reset began rippling through the data. The Dow fell harder, shedding 269 points (−0.56%) to 47,916.57, dragged by value-heavy industrials and financials positioning defensively ahead of bank earnings next week.

But the Nasdaq told a different story entirely. The composite gained 80.48 points (+0.35%) to 22,902.90, buoyed by Amazon’s 2.02% surge after CEO Andy Jassy published a combative shareholder letter defending the company’s $200 billion AI capital expenditure plan for 2026. The session’s split personality — inflation anxiety in one corner, AI exuberance in the other — perfectly captures where markets stand heading into bank earnings season.

The backdrop grew considerably stranger after the bell: The New York Times reported that a Molotov cocktail was hurled at the home of OpenAI CEO Sam Altman, adding a visceral new dimension to the intensifying backlash against frontier AI companies. The VIX held calm at 19.23, down 1.33% — but it’s hard to imagine that serenity lasting as the tectonic plates of inflation, AI, and geopolitics continue shifting beneath the market’s feet.

Closing Scoreboard

What Happened

This was a session defined by the tension between a backward-looking inflation shock and a forward-looking AI spending conviction. The March CPI print landed at 3.4% year-over-year — exactly at consensus but the highest since mid-2023 — driven overwhelmingly by the post-ceasefire energy price reset that has pushed gasoline costs sharply higher. Core CPI came in at 2.6%, roughly in line with expectations, while the February core PCE (released simultaneously in a rare same-day doubleheader) printed at 2.8%, matching the consensus figure cited by CNBC and the Daily Upside.

The market’s reaction was notably measured. Traders had been bracing for this headline number for weeks, and the fact that core measures remain relatively contained gave the Fed’s “patient” narrative enough oxygen to survive. But the Dow’s outsized decline reflects real concern: if energy-driven headline inflation proves stickier than expected — and with Brent crude still flirting with $96 — the math on rate cuts becomes increasingly unfavorable. The seven-day S&P win streak, the longest since October 2025, finally ran out of momentum.

The Nasdaq’s positive close was almost entirely attributable to Amazon, which surged 2.02% to $238.38 after CEO Andy Jassy published a 5,000-word shareholder letter that read more like a declaration of AI war than a corporate communication. “We’re not investing approximately $200 billion in capex in 2026 on a hunch,” Jassy wrote, while simultaneously taking shots at Nvidia (“customers want better price performance”) and Intel (noting that Amazon’s Graviton chip is now used by 98% of its top 1,000 cloud customers). Amazon also announced its Leo satellite network will launch in mid-2026, positioning it against SpaceX’s Starlink.

Mega-Cap and Key Movers

Tesla gained 0.98% to $349.00, benefiting from elevated oil prices that continue to accelerate EV adoption globally. China exported a staggering 349,000 electric vehicles in March alone — up 140% year-over-year — with high energy costs catalyzing demand across Southeast Asia, the Middle East, and Latin America. Microsoft was the session’s notable laggard among mega-caps, falling 0.59% as some investors rotated out of software names following Jassy’s pointed comments about Amazon’s competitive chip offerings.

Sector Breakdown

The session produced a narrow, bifurcated tape. Technology-adjacent sectors outperformed on the Amazon and AI narrative, while rate-sensitive sectors suffered from the hot CPI print pushing Treasury yields higher.

Global Markets

Europe closed mixed in muted trading ahead of the U.S. CPI data. The DAX finished essentially flat at 23,803.95 (−0.01%), the FTSE 100 was fractionally lower at 10,600.53 (−0.03%), the CAC 40 edged up to 8,259.60 (+0.17%), and the Euro STOXX 50 closed higher at 5,926.11 (+0.51%). European markets were cautious as the Axios Markets newsletter highlighted growing concerns about the “petrodollar” system — with Iran’s crypto tolls and yuan-denominated oil sales raising existential questions about dollar dominance in energy markets.

Asia was mixed overnight. Japanese equities benefited from continued yen weakness, while Hong Kong retreated slightly despite China’s blockbuster EV export data.

Fixed Income and Commodities

The 10-year Treasury yield jumped 4 basis points to 4.30%, its highest close in over a week, as the CPI print reinforced the case for the Fed to remain on hold through at least July. The 2-year yield also ticked higher, keeping the yield curve mildly inverted and signaling that rate-cut expectations continue to get pushed out. The CME FedWatch tool showed June cut probability falling toward 20% — a significant deterioration from the 35% probability seen just a week ago.

Gold pulled back modestly, with spot prices settling around $4,748.50 (−0.95%). The yellow metal had been trading near $4,795 earlier in the week, and the pre-CPI positioning drove some profit-taking. Bitcoin fell more sharply, dropping 1.6% to approximately $70,500. The crypto community noted that Bitcoin has now failed to clear $73,000 for the third time since the ceasefire — a well-defined triple-top pattern that could signal a near-term reversal if support at $69,000 doesn’t hold.

Corporate News

Jassy’s AI Manifesto

Amazon CEO Andy Jassy’s annual shareholder letter was the corporate story of the day. In 5,000 words, Jassy made an unapologetic case for the company’s $200 billion AI capital expenditure plan, noting that two large AWS customers actually asked to buy all of Amazon’s Graviton computing capacity for the year (Amazon declined). The letter was pointedly competitive: Jassy took direct aim at Nvidia’s pricing, highlighted Amazon’s Trainium custom chips, and teased the mid-2026 launch of Amazon Leo, a low Earth orbit satellite network designed to compete with SpaceX’s Starlink with speeds up to 1 Gbps.

Intel–Google Partnership Expands

Intel and Google announced an expanded chip partnership focused on AI CPUs, adding to Intel’s remarkable renaissance. The semiconductor’s stock has surged nearly 50% since the end of March, fueled by news of its role in Elon Musk’s Terafab AI chip project and the buyback of Apollo Global Management’s stake in its Ireland chip plant. The Google partnership further validates Intel’s pivot back toward relevance in the AI hardware stack.

Sam Altman Home Attacked

In a disturbing after-hours development, The New York Times reported that a Molotov cocktail was hurled at the home of OpenAI CEO Sam Altman. The incident underscores the increasingly hostile environment facing AI leaders and follows a broader pattern of anti-tech sentiment that has intensified alongside the Anthropic Mythos cybersecurity scare earlier this week. No injuries were reported.

Other Corporate Developments

• Disney (DIS) is planning approximately 1,000 layoffs under new CEO Josh D’Amaro, according to the Wall Street Journal.
• Sazerac joined the race to acquire Brown-Forman (BF.B) at a $14 billion valuation, competing with Pernod Ricard for the Jack Daniel’s parent.
• Ares Management will take private Whitestone REIT in a $1.7 billion all-cash deal.
• The DOJ launched an investigation into the NFL for potentially anticompetitive broadcast practices.
• Russia and Ukraine agreed to a temporary ceasefire, though expectations for durability remain low.
• The Artemis II crew is expected to splashdown tonight, completing a historic lunar mission.
• Investors sought to pull $20 billion from private credit funds in Q1, per the Financial Times, with Carlyle’s flagship fund the latest to face redemption pressure.

Economic Data

The Q4 GDP revision lower to 0.5% from 0.6% was largely overlooked by the market, but it adds to the mosaic of a slowing U.S. economy that is simultaneously grappling with imported energy inflation. The Fed’s dilemma is sharpening: growth is decelerating while headline inflation is accelerating — a quasi-stagflationary setup that leaves very little room for policy maneuver.

Looking Ahead — Bank Earnings Season

Monday brings Goldman Sachs (GS) Q1 earnings, followed by JPMorgan Chase (JPM) on Tuesday. These reports will be the first major test of how Wall Street navigated the volatile ceasefire period, the energy price spike, and the Anthropic Mythos cybersecurity scare. Consensus expects strong FICC trading revenue (given the massive volatility in oil and rates) but weaker advisory fees as M&A activity slowed during the conflict. Questions about banks’ AI spending and cyber defense investment — particularly in the wake of the Bessent-Powell emergency meeting this week — will dominate the earnings calls.

The AlphaEdge Take

The seven-day rally was always borrowed time. Markets needed CPI to come in meaningfully below consensus to justify another push higher, and instead they got an in-line print on a headline number that looks alarming at 3.4% — even if the core measures are better behaved. The S&P’s mere 0.11% decline on a day that could have triggered a much larger selloff is actually a sign of resilience: buyers are still lurking below the surface, supported by the AI narrative and the hope that bank earnings will deliver next week.

But the cross-currents are multiplying. Oil at $96 Brent is not going away — the NYT’s “worse than you think” framing echoes what energy analysts have been whispering for weeks: Iran’s weaponization of the Strait of Hormuz may have permanently altered the global oil market. The petrodollar system is being tested in real time, with Iran charging crypto tolls and the dollar’s centrality to energy markets no longer a given. Harvard’s Ken Rogoff called this moment “bigger than Liberation Day” — that is not hyperbole, that is a former IMF chief economist sounding an alarm.

Meanwhile, the AI theme continues to bifurcate the market. Jassy’s letter was a masterclass in competitive positioning, and Amazon’s surge shows investors are willing to reward companies that articulate a clear AI strategy backed by actual capital commitment. But the Molotov attack on Altman’s home, the Anthropic Mythos cybersecurity scare, and the growing regulatory backlash suggest the social license for AI development is fraying. That tension — between AI as the greatest investment opportunity of the generation and AI as a systemic risk to society — is going to define the next several quarters.

For the week ahead: bank earnings will set the tone. If Goldman and JPMorgan deliver strong FICC trading results and constructive guidance, the S&P could resume its march toward 6,900. If they disappoint or flag credit quality concerns in private credit or commercial real estate, the 6,750 support level from the ceasefire rally base will be tested quickly. The VIX at 19.23 is still below 20 — that calm is fragile. We expect the S&P to trade in a 6,750–6,880 range next week, with bank earnings as the key catalyst.
