Quantum Firms Pursue Public Listings Amid Breakthroughs

In March 2026, quantum computing companies are going public via SPAC mergers to raise capital after recent scientific advances; Xanadu Quantum listed on Nasdaq and the Toronto Stock Exchange, while Horizon Quantum debuted after merging with dMY Squared. Listings have been volatile—Xanadu rallied 15% then fell over 10% after-hours, Horizon is down about 18%, and Infleqtion has plunged more than 30%—as firms seek funds to commercialize emerging quantum capabilities.
