Billionaire Dan Loeb Doubles Down on Nvidia While Abandoning Another Mega-Cap Tech Giant
Dan Loeb's Third Point hedge fund is betting harder on artificial intelligence. According to Motley Fool, the billionaire investor piled into Nvidia for a fourth straight quarter during the first three months of 2025, expanding his position to nearly 3 million shares. That's a significant commitment to the AI chipmaker at a time when mega-cap tech valuations are drawing scrutiny across Wall Street.
But here's where it gets interesting.
While Loeb was loading up on Nvidia, he simultaneously dumped his entire stake in one of the "Magnificent Seven" stocks—the group of mega-cap technology companies that've dominated market gains. Motley Fool didn't specify which stock Loeb abandoned, but the move signals something important about how sophisticated investors are thinking about valuations right now.
The contrast is striking. On one hand, Loeb's repeated purchases of Nvidia suggest conviction that AI infrastructure remains underpriced, even as the stock's valuation has climbed substantially. On the other hand, his complete exit from another mega-cap suggests he's found more attractive opportunities elsewhere or believes that particular company's valuation has gotten out of hand.
So why does this matter?
Third Point manages billions in assets. When Loeb moves, institutional investors and fund managers pay attention. His quarterly shifts often precede broader market sentiment changes, not because he has magical foresight, but because his team conducts exhaustive research before redeploying capital at this scale.
Nvidia's dominance in AI chip manufacturing hasn't wavered. The company controls roughly 80% of the data center GPU market, making it functionally essential to anyone building large language models or training neural networks. Every major cloud provider—Amazon, Microsoft, Google—depends on Nvidia's technology. That moat isn't disappearing anytime soon.
Yet the real question is whether Nvidia's stock price has gotten ahead of itself. The company trades at premium valuations relative to traditional semiconductor peers, justified by its AI exposure but increasingly subject to debate among value-focused investors. Loeb's continued accumulation suggests he believes the market underestimates future earnings growth, particularly as demand for AI infrastructure accelerates over the next several years.
The exit from another Magnificent Seven stock is harder to interpret without knowing which company Loeb abandoned. Was it a valuation call? A belief that competitive threats are emerging? Or perhaps he simply found better risk-reward ratios elsewhere in his portfolio.
This portfolio shift arrives as institutional investors are recalibrating their positioning in mega-cap technology stocks. Some worry that concentration risk has become dangerous—too much of the market's gains are concentrated in too few companies. Others argue that the AI revolution justifies current valuations for the winners and that missing out on Nvidia-like opportunities is riskier than overpaying.
Frankly, Loeb's strategy suggests he's not choosing between those two camps. Instead, he's being selective within the mega-cap tech space: aggressively backing the infrastructure plays (Nvidia) while turning skeptical on others.
For individual investors watching this unfold, there's a practical lesson here. Conviction in a single thesis—AI infrastructure will matter enormously—doesn't mean treating all beneficiaries equally. Loeb's willingness to exit one Magnificent Seven position entirely while repeatedly buying another shows that scale and market dominance aren't automatic reasons to hold everything that looks expensive.
Third Point's moves will likely influence how other hedge funds and institutional managers think about their own mega-cap tech exposure in coming quarters. Watch for whether other sophisticated investors follow Loeb's lead on either side of this trade.
