Special purpose acquisition company Dune Acquisition III, which focuses on digital assets, sports entertainment, software-as-a-service (SaaS), and artificial intelligence, submitted a filing with the U.S. Securities and Exchange Commission (SEC) on Tuesday. The company aims to raise up to $150 million through an initial public offering (IPO). Dune Acquisition III plans to offer 15 million units at $10 per unit to raise $150 million. Each unit consists of one share of common stock and one-third of a warrant, with the warrants exercisable at $11.50 per share. The SPAC is led by Chief Executive Officer and Chairman Carter Glatt, formerly the head of corporate development and senior vice president at GTY. Chief Financial Officer Jeron Smith, founder of Unanimous Media, The Incubation Lab, and Heir, has also joined the team. The SPAC intends to target businesses in the digital assets, sports entertainment, SaaS, and artificial intelligence sectors. The management team's previous SPAC projects include Dune Acquisition, which went public in 2023 and completed a business combination with hydrogen supplier Global Gas (OTC: HGAS; down 99.7% from its $10 issue price), and Dune Acquisition II (IPODU; up 4.4% from its $10 issue price), which went public in 2025. The company, based in West Palm Beach, Florida, was founded in 2025 and plans to list on the Nasdaq, though a ticker symbol has not yet been selected. Dune Acquisition III submitted its application confidentially on November 6, 2025. Clear Street is acting as the sole book-running manager for the offering.
