ON Semiconductor provides the silicon carbide MOSFETs (which are semiconductors that switch or supply voltages) for electric vehicle components for EV drive trains, such as traction inverters, DC/DC inverters, on-board chargers, fast chargers and energy storage applications. ON is Aehr’s number one customer because they must test silicon carbide semiconductors for failures before supplying silicon carbide-based powertrains and charging systems for key Electric Vehicle OEMs, such as Tesla, Volkswagen, Mercedes Benz, Nio and BMW. EliteSiC is the portfolio of SiC products that ON provides to popular EV OEMs to increase electric power train efficiency and extend EV range. Of the estimated $8.13 billion in revenue that On Semi is expected to report this year FY2023, $1 billion is from silicon carbide components. This is up 5X from 2022. In Q1, the SiC revenue doubled from Q4.

3 AI Trends Driving the 2026 Cybersecurity Stocks Rally

Cybersecurity stocks surged in 2026 as AI-enabled attacks rose 89%. We look at how AI threats, AI labs and platform consolidation are driving demand.

Beyond Hyperscalers: Here’s the Next $1 Trillion AI Infrastructure Opportunity

Since 2022, Big Tech capex has been the clearest barometer of AI demand. But the market’s reaction to Google’s latest earnings shows investors are questioning how long that spending can last. While the market frets over hyperscalers’ cash flows, a second wave of AI infrastructure spending has quietly emerged, driven by enterprises and neocloud customers.

Google’s $250 Billion AI Chip Opportunity Takes Aim at Nvidia

In April, there was a major shift in the AI accelerator market, and for once, it didn’t come from Nvidia. Six months later, merchant TPUs are moving from announcement to commercial execution, with Google recognizing its first revenue from TPU systems in Q2 (from a small base). Last quarter, Cloud revenue growth accelerated to 82% for $24.8 billion, compared to $22.5 billion expected. In addition, new details around the TPU 8t show that Google’s threat to Nvidia is not limited to inference. At the time, we pointed out that Google may be one of Nvidia’s strongest AI challengers, as Big Tech is closest to the problems that accelerators must solve. The problem that Google is prioritizing is lower cost per token, with token economics becoming a predominant concern as AI spending is pushing Big Tech’s free cash flows into the red. Below, we discuss two reasons why Google’s AI story is about to change, not from advancements in AI software, but by going after one of the most profitable hardware businesses the tech industry has ever seen.
