ON vs WOLF: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. ON and WOLF share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined ON and WOLF exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

onsemi (ON Semiconductor) is a US-based semiconductor company focused on intelligent power and sensing technologies. Its power products, including silicon and silicon-carbide devices, manage and convert electricity in electric vehicles, industrial equipment, and power supplies, while its sensing products, such as image sensors, are used in automotive cameras and industrial vision. The company has deliberately concentrated on automotive and industrial markets, where semiconductor content per vehicle and per machine is rising, and it has been repositioning its manufacturing and product mix toward higher-margin, differentiated products rather than commodity chips.

Wolfspeed, Inc. is a pure-play silicon carbide company that makes SiC wafers and substrates and turns them into power devices used in electric vehicles, industrial equipment, energy systems, and increasingly AI data centers. It is unusually vertically integrated, mastering both the difficult SiC crystal-growth and wafer process and the downstream power-device fabrication. Its flagship asset is the Mohawk Valley 200mm SiC fab in Marcy, New York, which it has been ramping while winding down older 150mm capacity in Durham. Revenue has been modest and volatile, around $150 million in the third quarter of fiscal 2026 with similar guidance for the following quarter, and the company was still reporting losses as it scaled production, though AI data-center demand grew sharply off a small base.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• ON drivers: AI data-center power opportunity; Rising semiconductor content in vehicles.
• WOLF drivers: Silicon carbide adoption in electrification; Mohawk Valley fab ramp.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is cyclicality: onsemi's automotive and industrial end markets rise and fall with the economy, vehicle production, and factory investment, so revenue and earnings can swing sharply and a soft patch can pressure results even amid long-run content growth. For WOLF, the overriding context is that WOLF is a post-bankruptcy equity: legacy shareholders were nearly wiped out, and today's holders sit behind a company that still needs to prove it can grow revenue and reach sustained profitability.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick ON if you believe its drivers more; WOLF if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the ON and WOLF guides.

ON. Figures are approximate and tied to the asOf date; verify live numbers before acting. For a cyclical semiconductor company, earnings multiples can look high near a cyclical trough (when profits are depressed) and low near a peak, so it helps to consider where automotive and industrial demand sit in the cycle rather than a single P/E. The AI data-center growth adds a faster-moving element to what has been a more cyclical, content-driven story.

WOLF. Figures are approximate and tied to the asOf date; verify live numbers before acting. Because the company emerged from Chapter 11 in late 2025 with an entirely new capital structure, traditional trailing multiples are not meaningful and pre-2025 financials and share counts do not map to today's equity. Investors are effectively pricing the odds and timing of a successful SiC ramp and a path to profitability, not a stable earnings stream, which makes valuation highly assumption-dependent.

Headline figures (approximate, Jul 2026): ON shows revenue (q1 2026) ~$1.51 billion, above the midpoint of guidance, gaap gross margin ~38.5% in Q1 2026, non-gaap diluted eps ~$0.64 in Q1 2026, ai data-center growth up more than 30% sequentially; expected to roughly double year over year in 2026; WOLF shows quarterly revenue (q3 fy2026) ~$150 million, with next-quarter guidance around $140 to $160 million, profitability Still loss-making as the Mohawk Valley fab ramps; margins improving off low levels, debt after restructuring Cut roughly 70%, from about $6.7 billion to around $2 billion post-emergence, shares outstanding ~45 million new shares after the Renesas equity issuance cleared in early 2026.

ON and WOLF are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
