Solid Power (SLDP) Stock Forecast: What Could Drive It in 2026
Short answer
What is actually driving Solid Power (SLDP) right now is Automaker and battery-partner relationships: Solid Power has multi-year agreements and joint development work with BMW, Ford, and SK On, and in late 2025 added a joint evaluation agreement with Samsung SDI and BMW aimed at a demonstration vehicle powered by all-solid-state battery technology. Revenue and grant income (Q1 2026) is ~$3.1 million, down sharply year over year and driven mainly by SK On and U.S. Department of Energy milestones; effectively pre-revenue from a product-sales standpoint. If that keeps playing out, the setup is favourable; the risk to it is commercialization is unproven: Solid Power generates minimal revenue (largely partner milestones and grants) and is years away from any solid-state battery reaching mass production, so the timeline is long and uncertain. No one can predict where SLDP trades, and Walnut does not publish targets, so treat this as a scenario, not a price target or prediction.
What could drive Solid Power (SLDP) higher?
Automaker and battery-partner relationships
Solid Power has multi-year agreements and joint development work with BMW, Ford, and SK On, and in late 2025 added a joint evaluation agreement with Samsung SDI and BMW aimed at a demonstration vehicle powered by all-solid-state battery technology. These partners give the company validation channels and potential routes to scale. The arrangements are evaluation and development stage, not committed high-volume supply contracts.
Electrolyte-supplier and licensing model
Rather than building its own gigafactories, Solid Power has pivoted toward supplying sulfide solid electrolyte and licensing its technology, a capital-light approach intended to stretch its cash and shift heavy manufacturing capital to partners. It is scaling pilot electrolyte capacity (roughly 30 metric tons toward about 75 metric tons targeted by year-end 2026) and commissioning a continuous production line. Whether this translates into recurring material sales or licensing revenue is still unproven.
Cash cushion and runway
As of March 31, 2026 the company reported total liquidity (cash, equivalents, and available-for-sale securities) of roughly ~$435 million with no debt, boosted by a registered direct offering during the quarter. Management guided to roughly ~$85 million to ~$100 million of cash investment in 2026, implying a multi-year runway. A Department of Energy grant of up to ~$50 million supports the build-out.
Solid-state battery upside potential
If sulfide-based solid-state batteries deliver on promises of higher energy density and improved safety, the addressable market across electric vehicles and other applications is large. Solid Power's claimed compatibility with existing lithium-ion manufacturing lines is its differentiator. This is a long-dated, binary technology bet rather than a near-term earnings story.
What could weigh on SLDP?
Commercialization is unproven: Solid Power generates minimal revenue (largely partner milestones and grants) and is years away from any solid-state battery reaching mass production, so the timeline is long and uncertain. The company continues to post operating losses and may need to raise capital again, which can dilute existing shareholders. It faces well-funded competition from QuantumScape, Toyota, Factorial Energy, and incumbent lithium-ion battery makers, any of whom could reach scale first or with a different chemistry. Demand for the technology also depends on the pace of EV adoption, which has been uneven.
How to think about a SLDP forecast
Rather than chasing a price target, it tends to help to weigh the drivers above against the risks, decide how long you are willing to hold, and size the position so a wrong call is survivable. A “forecast” is really a probability-weighted view of those drivers playing out, not a number.

The bottom line on the SLDP outlook
The bottom line: what is driving Solid Power (SLDP) is Automaker and battery-partner relationships, with revenue and grant income (q1 2026) at ~$3.1 million, down sharply year over year and driven mainly by SK On and U.S. Department of Energy milestones; effectively pre-revenue from a product-sales standpoint. If that keeps playing out the setup is favourable; the risk is commercialization is unproven: Solid Power generates minimal revenue (largely partner milestones and grants) and is years away from any solid-state battery reaching mass production, so the timeline is long and uncertain. No one can predict the price, so treat any SLDP forecast as a scenario, not a target or prediction, and decide from your own thesis and time horizon. Walnut is not an investment adviser.

FAQ
What is the forecast for Solid Power (SLDP)?
+
No one can reliably predict where SLDP will trade, and Walnut does not publish price targets. What is more useful is the setup: the drivers that could push Solid Power higher and the risks that could weigh on it. This page lays out both so you can form your own view. Not a recommendation.
What could drive SLDP higher?
+
The main growth drivers are Automaker and battery-partner relationships; Electrolyte-supplier and licensing model; Cash cushion and runway. Whether they play out is the real question, not a guaranteed path.
What are the risks to SLDP?
+
Commercialization is unproven: Solid Power generates minimal revenue (largely partner milestones and grants) and is years away from any solid-state battery reaching mass production, so the timeline is long and uncertain. The company continues to post operating losses and may need to raise capital again, which can dilute existing shareholders. It faces well-funded competition from QuantumScape, Toyota, Factorial Energy, and incumbent lithium-ion battery makers, any of whom could reach scale first or with a different chemistry. Demand for the technology also depends on the pace of EV adoption, which has been uneven.
Will SLDP stock go up in 2026?
+
Nobody knows, and anyone who says they do is guessing. Solid Power's direction depends on whether the drivers above outweigh the risks, plus the broader market. Focus on the thesis and your time horizon rather than a single-year call.
Is SLDP a buy?
+
That depends on your thesis, time horizon, and what you already own, not on a forecast. See the SLDP "is it a buy?" page for a framework. Walnut is not an investment adviser.
