Amprius shares jump 21 per cent on battery market growth forecast

Amprius Technologies Inc. (NYSE:AMPX) shares rose 21.50 per cent to close at $20.85 on Thursday, following the release of a market analysis by SNS Insider. The report projects the US silicon anode battery market to reach $31.27 billion by 2035, representing a compound annual growth rate of 51 per cent between 2026 and 2035.

The forecast indicates a significant expansion from a base value of $536.6 million in 2025. SNS Insider attributed this growth trajectory to substantial federal investment in battery innovation, the expansion of electric vehicle manufacturing capacity, and the increasing commercialisation of advanced battery technologies.

Amprius was identified in the report as a primary beneficiary of these trends. The company is recognised as a leader in advanced lithium-ion technology, specifically delivering silicon-anode batteries that offer up to twice the energy density, range, and flight time of conventional graphite-based cells.

The analysis also highlighted comparable opportunities for peers such as Group14 Technologies Inc., Sila Nanotechnologies Inc., and Enovix Corporation. Industry analysts regard silicon-based anodes as the next major innovation in advanced lithium-ion batteries, driving the high growth rates projected across the sector.

In addition to the US outlook, the SNS Insider report noted strong growth potential in Europe, where the silicon anode battery market is expected to climb to $7.62 billion by 2035. This represents a compound annual growth rate of 48.09 per cent, rising from a 2025 valuation of $146.2 million.

Earlier this month, Amprius announced a strategic collaboration with Matternet to advance the performance of the latter’s M2 aircraft. The partnership underscores the company’s focus on high-energy applications beyond traditional automotive markets.

While the market reaction was positive, some financial commentary noted that certain artificial intelligence stocks may offer greater upside potential with less downside risk than AMPX, referencing separate reports on AI stocks benefiting from tariff policies.
