Investors searching for solid state battery companies to invest in are looking at a field that is mostly promise and partly product, and it pays to know which kind of company you are buying. The solid state story has attracted a mix of pure-play startups, established battery makers, and giant manufacturers with research programs, each carrying a very different risk profile. Here is how to sort them and what to watch for.
The Pure Plays
The pure-play solid state companies are startups built entirely around the technology, and they are the most direct way to bet on it. The trade-off is that many of them are pre-revenue or nearly so, funding research with fresh share issuance while they chase a manufacturing breakthrough. A few have announced partnerships with automakers or pilot production lines, which are useful signals but not yet volume revenue.
These names swing hard on news. A successful pilot run or a major partnership can send the stock up sharply, while a slipped timeline can do the reverse. They are the highest-upside, highest-risk corner of the battery sector, and they suit money that can be lost entirely.

The Diversified Ways In
The lower-risk route is through companies that are not solid state bets but have a solid state program inside a much larger business. These include the big automotive battery makers and diversified electronics and materials companies that are quietly funding solid state research. Owning one of these does not give you a concentrated solid state bet; it gives you a profitable core business with a free option on the technology.
The downside is dilution of the story. If solid state succeeds, these companies will capture only a fraction of the upside, because solid state is one program among dozens. But they will not go to zero if it fails, which is the risk that comes with the pure plays. That trade-off is the central decision for anyone hunting solid state exposure.
Signals That Actually Matter
When evaluating any of these companies, the useful signals are not the press releases. Look for pilot production lines that are actually running, named customers with purchase commitments, and revenue that is starting to appear, however small. A partnership announcement without volumes is marketing; a signed supply agreement with a real manufacturer is progress. The gap between the two is where most of the hype lives.
It also helps to check how the company is funded. A solid state startup that is constantly selling shares is diluting early holders while it waits for the technology to mature, and that dilution is a real cost even if the science eventually works. These are the same questions that apply to the silicon-anode company in the promo, and our Elon’s Missing Pieces teardown walks through them.
The Time-Horizon Reality
The honest view is that solid state is a multi-year story. The technology will not arrive all at once, and the companies that win may not be the ones leading the headlines today. For most investors, the sensible exposure is a small, patient position in either a diversified manufacturer or a diversified basket, not a concentrated bet on a single pre-revenue startup. The marketing around “the next battery” routinely collapses that timeline, and the collapse is where investors get hurt.
How to Size the Position
Because solid state is a multi-year story with most pure plays still pre-revenue, position sizing is the most important decision an investor in this space makes. The sensible approach is to treat any pure-play position as venture-style money: small enough that losing it entirely is acceptable, and held with the patience to wait through multiple slipped timelines.
The diversified manufacturers can be sized more like ordinary equity positions, since their value does not hinge on the technology. The key discipline is to decide which kind of exposure you want before buying, then size accordingly. A portfolio that accidentally treats a pre-revenue startup like a blue chip is where the real losses happen, and the promo’s tendency to present speculative names as sure things is exactly the framing to guard against.
The Bottom Line
Solid state battery companies to invest in fall into two camps: high-risk pure plays priced on potential, and lower-risk diversified manufacturers carrying the technology as one program among many. The category is real, but it is early, and the difference between a partnership headline and a signed supply deal is everything. Size any position accordingly, and give the technology the years it is going to take.
