Investment Ideas

Robotics and physical AI may be one of the next big investment themes after the AI software boom. AI models are powerful, but companies also need sensors, compute systems, vehicle intelligence, factory automation, and machines that can act in the real world.

One stock that fits this theme is Aptiv (NYSE: APTV), a large-cap technology and advanced mobility company working on intelligent edge systems, ADAS, sensing, software-defined vehicles, and automation-related hardware.

SpaceX could soon become one of the biggest IPO stories in market history. According to reports, the company may target an IPO price of around $135 per share, raise about $75 billion, and reach a valuation close to $1.75 trillion.

That would make SpaceX one of the most valuable public companies from day one. But the big question for investors is simple: is the valuation already too high?

SpaceX is not a traditional aerospace company. Investors are looking at it as a combination of rocket launches, Starlink satellite internet, defense contracts, reusable rocket technology, and future space infrastructure.

That makes the company unique, but it also makes valuation very difficult.

At the reported IPO valuation, investors would be paying a very high price compared with current revenue. This means the market would be pricing in many years of strong future growth before the company proves it as a public stock.

Robotics and machinery may be the next step after the AI software boom. AI can analyze data, but companies still need machines that can move products, automate warehouses, reduce labor pressure, and make supply chains faster.

One stock that fits this theme is Symbotic (NASDAQ: SYM), a warehouse robotics and automation company focused on AI-enabled supply chain systems.

The $20 Trillion Question

A $20 trillion market cap sounds extreme at first glance. But Nvidia is no longer trading on a simple semiconductor narrative. It is increasingly being valued as the core infrastructure layer of the AI economy, and that changes the scale of the opportunity. At roughly $4.53 trillion today, a $20 trillion valuation by 2030 would require Nvidia to rise a little more than 4.4x from current levels, which implies a stock price near $757 per share if the share count stays roughly similar.

Nvidia Is Growing From an Already Massive Base

The reason that scenario cannot be dismissed outright is simple: Nvidia’s business is still compounding from an already massive base. In fiscal 2026, Nvidia generated $215.9 billion in revenue, up 65% year over year. Fourth-quarter data center revenue reached $62.3 billion, up 75%, while full-year gross margin held above 71%, showing that this is not…
