The AI gold rush is no longer confined to Wall Street’s "Magnificent Seven" tech giants. As of 2025, the AI boom has spilled over into a broader ecosystem, with companies like Oracle, Broadcom, and Palantir surging ahead while some original members (looking at you, Tesla and Apple) struggle to keep up. Index providers are scrambling to formalize this shift, with Cboe launching a "Magnificent 10" index. Meanwhile, energy producers, chipmakers, and even obscure software firms are cashing in on the AI wave. Here’s why the market’s obsession with the "Mag 7" might be yesterday’s news.

How Did the Magnificent Seven Dominate the AI Boom Initially?

When ChatGPT kicked off the AI frenzy three years ago, investors piled into Big Tech like it was the last lifeboat on the Titanic. According to Bloomberg data, the S&P 500’s 70% rally since 2023 was driven mostly by just seven companies: Nvidia, Microsoft, Alphabet, Meta, Apple, Amazon, and Tesla. At their peak, they accounted for over 35% of the entire index. Even now, analysts project their 2026 earnings to grow 15% versus 13% for the rest of the S&P 500. But dig deeper, and cracks emerge. Nvidia and Meta are still flying high with 21-33% gains this year, while Apple and Tesla are dragging their feet—proof that not all tech giants are equal in the AI race.

Why Are Analysts Debating New AI Power Rankings?

Wall Street’s obsession with categorizing winners has led to some creative rebranding. Seaport Research’s Jonathan Golub wants to ditch Tesla for a "Big Six." Melius Research’s Ben Reitzes added Broadcom to create an "Elite Eight." But as Jurrien Timmer of Fidelity ($16.4 trillion AUM) puts it: "New winners always replace old winners—that’s capitalism." Oracle’s 75% surge this year (thanks to AI cloud services) and Palantir’s ridiculous 135% rally prove his point. Remember the Nifty Fifty? The Four Horsemen? FAANG? Each group had its moment before fading. History’s repeating itself with AI.

How Are Index Makers Adapting to the AI Expansion?

Cboe Global Markets made it official on September 10, 2025, launching the "Magnificent 10 Index." The original seven got company: Broadcom, Palantir, and AMD joined the club. Oddly, Oracle was excluded despite its monster 1992-style single-day rally that same day. Nick Schommer at Janus Henderson ($34.7 billion AUM) told us, "Oracle and Broadcom are undeniably part of this now." Cboe’s criteria—liquidity, AI leadership, market cap—show how the game has changed. Taiwan Semiconductor, Broadcom, and Palantir are now ecosystem linchpins, while legacy players like Adobe face existential doubts.

Which Dark Horse Companies Are Winning the AI Race?

Forget the usual suspects—Arista Networks (cloud networking), Micron (memory chips), and Western Digital (storage) are quietly printing money from AI demand. Even energy firms are cashing in as data centers guzzle power. But the real intrigue lies in private markets: OpenAI’s rumored $500B valuation, Anthropic’s rise, and SpaceX’s AI ambitions remind us that the most disruptive players might not even be publicly traded. As for Tesla? Its EV headaches make AI bets on robotaxis look desperate. Apple loyalists still believe the iPhone will morph into an AI gateway device, but that faith is wearing thin.

What’s Next for the AI Investment Landscape?

The Mag 7’s era isn’t over—it’s just getting crowded. With AI permeating every sector from healthcare to agriculture, the next winners could come from left field. (Biochip makers, anyone?) One thing’s clear: betting solely on yesterday’s tech darlings is like bringing a flip phone to a drone race. As Palantir’s 135% rally proves, niche players can become market-shaking giants almost overnight. This article does not constitute investment advice.

FAQs: AI’s Market Shakeup

Why is Tesla underperforming in the AI boom?

While Tesla pushes autonomous driving and robots, its Core EV business faces brutal competition. Investors see clearer AI plays elsewhere.

How did Palantir become a top Nasdaq performer?

Its pivot to AI-driven data analysis for governments and enterprises fueled a 135% surge in 2025—a classic "niche to necessity" story.

Will private AI firms like OpenAI go public soon?

Unlikely before 2026. Their sky-high valuations and ample private funding reduce pressure for IPOs.
