Wolfspeed (WOLF) is the name most investors think of first when they hear silicon carbide, and it is the natural rival to the “Elon Musk’s NEW AI Masterplan” pitch’s applications pick, onsemi. The pitch promises that three “secret” stocks can “unleash enough wealth to make every household in America $2.38 million,” and it points at onsemi as the “backdoor” into the robotics wave. Wolfspeed is the pure-play way to bet on the same underlying material, which makes the comparison between the two the fastest way to understand the pitch.
Both companies sell into the same electrification story. They just carry it differently.
What Wolfspeed does
Wolfspeed is a pure-play silicon carbide company. It grows the silicon carbide wafers, makes devices on them, and sells them into electric-vehicle inverters, charging infrastructure, and industrial power systems. Because silicon carbide handles higher voltages and temperatures with less wasted heat than plain silicon, it is the material of choice for the most demanding power electronics.
The trade-off is focus. Wolfspeed’s entire business is tied to the silicon carbide ramp, which means its fortunes rise and fall with how fast the material gets adopted and how well it manages the cost of building out fabrication capacity.
Where onsemi differs
onsemi is the second-largest power chipmaker in the world, with a broad silicon power business plus a leading position in automotive image sensors. It has built silicon carbide capacity through its own fabs and acquisitions, but silicon carbide is one slice of a larger, profitable company rather than the whole story.
That is why the pitch lands on onsemi for the applications step. The pitch says onsemi is “already supplying Tesla with a key piece of sensor technology,” which is accurate, and it argues that onsemi’s power-management chips will let the Optimus robot “move efficiently, stay cool, and run longer without needing to stop and recharge as often.” The image-sensor strength gives onsemi a second angle on robots that a pure silicon carbide play like Wolfspeed does not have.
What the pitch means for both
The Masterplan’s thesis is that robots will need power and sensing chips in volume, and that thesis is positive for the whole silicon carbide complex. If Optimus and its rivals reach mass production, demand for high-efficiency power chips rises, which benefits both a diversified supplier like onsemi and a pure play like Wolfspeed. The difference is concentration: Wolfspeed gives you more direct exposure to the material, while onsemi gives you exposure to the material plus a profitable base business and a sensing story.
The honest caveats
The caveats around the pitch apply to both names. onsemi trades at about 18 times forward earnings with a roughly $28 billion market cap, and its tease price equals the current close of $71.67, a re-pitch at the current price. Its revenue today is overwhelmingly automotive and industrial, and the robot catalyst is years away. The ad’s marquee number, “on the receiving end of up to $500 billion in 2027 alone,” is aimed at ASML, whose annual revenue is around $30 billion, and it is a rhetorical flourish. The “39 hedge funds are investing” line is filler, true of essentially every large-cap.
The reason the pure play trades the way it does is the cost of the ramp. Building silicon carbide fabrication capacity is expensive, and Wolfspeed has funded a heavy expansion in the United States that weighs on its near-term results. When the ramp is going well, that spending looks like an asset; when demand softens, it looks like a drag. That is the concentrated risk a diversified name like onsemi avoids, and it is the single most important thing to understand before choosing between the two. The Masterplan thesis is directionally good for both companies, but the path and the volatility are very different. Neither approach is wrong; they simply answer different questions about how much risk you want to take to reach the same eventual market.
The bottom line
Wolfspeed and onsemi are two different ways to play the same silicon carbide and electrification story, one concentrated and one diversified. The Masterplan pitch favors the diversified one with a sensing angle, but both are legitimate if you understand which risk you are taking.

The offer is worth stating plainly. The Near Future Report costs $179 for the first year and renews at $199, with a 30-day refund window, so you can read the full reports and ask for your money back if they do not hold up. Subscribing unlocks the special report the pitch is built around, the “Manifested AGI Revolution,” which names the stocks the ad teases. The fine print worth remembering is that these are large, well-covered companies trading near their current prices, not the “secret” the headline suggests.
