The Rise of a New Mag 7 | GoAI Insights

For the past two years, the U.S. stock market has been dominated by the so-called “Mag 7” — Apple, Microsoft, Google, Amazon, Nvidia, Tesla, and Meta. They drove nearly every rally, adding more than five trillion dollars of market value in a single year. To many investors, they looked untouchable.

But 2025 is telling a different story. The old Mag 7 still make up about 36 percent of the S&P 500’s total market cap, but their momentum has slowed. In the first three quarters of this year, they added just over three trillion dollars, a huge number but far less than before. The giants remain powerful, but their run is no longer unstoppable.

At the same time, a new set of players is stepping into the spotlight. Broadcom, Oracle, and Palantir have quickly climbed the leaderboard and are now being called the “new Mag 7.”

The Companies Taking the Baton

The numbers speak for themselves.

• Broadcom $AVGO has become the fourth-biggest contributor to the S&P 500 this year, adding more market value than Apple, Tesla, Amazon, or Meta. Its CEO has promised to stay in charge through 2030, keeping the focus on AI chips and custom solutions.

• Oracle $ORCL is making headlines with its cloud business. The company just signed a massive $300 billion deal with OpenAI to provide computing power over five years starting in 2027. Oracle also said its AI-driven cloud revenue could top half a trillion dollars in the next few months. The stock jumped more than 24 percent in September alone.

• Palantir $PLTR , once seen as a mysterious defense contractor, is now making real progress in the commercial market with its AI platforms. Its market value has grown by more than $260 billion this year, putting it among the top ten contributors to the S&P 500.

Each of these companies plays a different role in the AI ecosystem — hardware at Broadcom, cloud infrastructure at Oracle, and AI software at Palantir. What unites them is that they all sit at critical points in the AI supply chain.

Why the Old Mag 7 Are Slowing

This shift does not mean the old Mag 7 are fading away. They are still giants, but their growth paths look less steep than before.

• Apple $AAPL has gained only 2.7 percent this year as it takes its time rolling out AI features, while rivals are racing ahead.

• Amazon $AMZN is up just 1.3 percent, with slower growth at AWS and growing competition from Microsoft and Google in AI cloud services.

• Tesla $TSLA has risen 10 percent but is losing electric vehicle market share in Europe, facing weaker demand and tougher competition worldwide.

Meanwhile, Nvidia $NVDA , Google $GOOGL , Microsoft $MSFT , and Meta $META are still soaring with gains of 40, 29, 23, and 24 percent respectively. But the group as a whole is no longer moving in lockstep the way it once did.

The Logic Behind the Shift

To me, the logic behind this handover is clear. AI is moving into its second phase.

1. The first phase was all about infrastructure — the cloud and the chips that powered the boom. That was the sweet spot for the original Mag 7.

2. The second phase is more about applications and specialization. Growth is no longer concentrated in a few mega-caps. Companies that can carve out a strong position in specific parts of the AI ecosystem are now the ones taking off.

Investors are hunting for the next growth engine. The old Mag 7 have already delivered much of their upside, while companies like Broadcom, Oracle, and Palantir are just getting started.

What Investors Should Watch

There are a few lessons here.

• AI is no longer a single story. It is becoming an entire ecosystem, and different parts — chips, cloud, software — can each be investment themes on their own.

• The old Mag 7 remain strong but may play more of a defensive role now, rather than leading the charge.

• The new Mag 7 have greater upside but also bigger risks. Palantir’s business model is still evolving, Oracle’s growth depends heavily on giant contracts, and Broadcom’s valuation is already high.

My Take

What excites me most is that AI’s power is spreading out. It is no longer just in the hands of a few mega-caps. The market is becoming more diverse, and opportunities are more scattered. For investors, that means spotting which of the new stars can become long-term leaders while staying mindful of the risks.

It feels like a relay race. The old Mag 7 are still running, but they are no longer sprinting alone. The new Mag 7 are catching up fast and could take the torch. That makes the next few years of the AI boom even more fascinating — and a true test of investor judgment.
