Solidion (STI) Surges Over 350% on Space Battery Breakthrough, SpaceX IPO Mania

Solidion Technology (STI-US) shares skyrocketed over 350% on June 4, 2026, triggering multiple trading halts, after the company announced a patent breakthrough in extreme-climate battery systems targeting space applications. The rally was amplified by mounting excitement over SpaceX's historic initial public offering. The company unveiled its Generation Extreme-Climate Battery (Gen-ECB) platform, capable of operating in high radiation, vacuum, and extreme temperatures. It aims the technology at low-Earth orbit AI data centers, lunar bases, and deep-space missions, citing potential synergy with SpaceX's Starship flights. The Dallas-based firm stated its batteries could power lunar habitats and provide backup during solar eclipses. SpaceX filed updated IPO documents with the SEC on June 3, planning to list on June 12 at $135 per share. The offering would raise $75 billion at a $1.77 trillion valuation, making it the largest IPO in history and eclipsing Tesla and Meta in market capitalization. The listing has fueled a speculative frenzy in space-themed stocks, with Solidion emerging as the latest beneficiary despite limited revenue. The Dow Jones Industrial Average closed at a record high, up 1.7%, while gold surged past $4,500 an ounce for the first time.
