Silicon carbide is the material quietly replacing ordinary silicon inside the most demanding power electronics, from electric-vehicle drivetrains to the inverters that will one day run humanoid robots. It shows up in the “Elon Musk’s NEW AI Masterplan” pitch from Brownstone Research’s Near Future Report, because the pitch’s applications pick, onsemi, is a major player in the material even though it is not the name most investors associate with it.
The pitch promises that three “secret” stocks can “unleash enough wealth to make every household in America $2.38 million.” The silicon carbide story is the underlying technology behind part of that promise, so it is worth understanding what the material does and why it matters.
What silicon carbide does better
Silicon carbide, or SiC, is a compound semiconductor that can handle higher voltages, higher temperatures, and faster switching than plain silicon. That means power chips made from it waste less energy as heat and can run at frequencies silicon cannot match. In an electric vehicle, a silicon carbide inverter can add a few percent of driving range, because more of the battery’s energy reaches the wheels.
The trade-off is cost. Silicon carbide wafers are harder to grow and more expensive to process than silicon, which is why the material has concentrated first in premium applications like high-end electric vehicles and fast chargers, and why it is spreading outward as manufacturing scales up.
Why robotics leans on it
A humanoid robot is a battery-powered machine with dozens of motors packed into a small body. Efficiency and heat matter enormously there, because there is nowhere to put a big cooling system. Silicon carbide power chips switch fast and run cool, which is exactly the profile a robot joint wants. The Masterplan pitch makes this point indirectly, arguing 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.”
Where onsemi fits in silicon carbide
onsemi is the second-largest power chipmaker in the world, and it has been building out silicon carbide capacity across its own fabs and through acquisitions. That gives it exposure to the material without being a pure play. The pure-play rival most people think of is Wolfspeed, which is far more concentrated in silicon carbide but also more exposed to the material’s ramp and its balance-sheet costs.
The pitch’s specific claim about onsemi is that it is “already supplying Tesla with a key piece of sensor technology.” That is real, and Tesla is one of the largest users of silicon carbide in the industry, which makes the extension of that relationship to robot power chips plausible.
The fine print on the stock
The honest caveats mirror the rest of the Masterplan pitch. 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. That is a re-pitch at the current price. Its revenue today is dominated by automotive and industrial demand, and the robot catalyst is years away.
There is also a marquee number in the ad that belongs to a different pick. The “$500 billion in 2027” figure is aimed at ASML, the chip-equipment maker whose annual revenue is around $30 billion. It is a rhetorical flourish, and it should make a reader check the rest of the claims.
The adoption curve is the part investors tend to underestimate. Silicon carbide costs more than silicon, so it has concentrated first where the efficiency gain pays for itself fastest, in premium electric vehicles and fast chargers. As wafer costs come down and manufacturing capacity scales, the material spreads into more vehicles and industrial gear. That is a genuine, multi-year tailwind, but it is a ramp rather than a switch, and the timing of that ramp is what drives both the pure-play and the diversified names. onsemi gives you that exposure inside a much larger, already profitable silicon business, which is why its stock does not swing as hard on silicon carbide news as a focused rival’s does. For an investor who wants the material’s upside without the pure-play volatility, that diversified exposure is the main argument in onsemi’s favor.
The takeaway
Silicon carbide is a real technology shift with a clear efficiency story, and onsemi is a credible way to get diversified exposure to it. The pitch compresses a multi-year ramp into a near-term headline, but the material story itself is sound.

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.
