IPO Status
SPAC merger announced
Once the listing closes, Terra Quantum will join the tracked pure-play quantum stocks on this site.
Terra Quantum is expected to go public in the second half of 2026 via a business combination with Axiom Intelligence Acquisition Corp 1 (Nasdaq: AXINU), announced as a definitive agreement on May 26, 2026. The deal implies a $3.5 billion equity value and $3.6 billion pro forma enterprise value, with existing Terra Quantum shareholders rolling 100% of their equity and holding about 92% of the combined company.
Terra Quantum's own post-merger ticker is expected to be "TQ" on Nasdaq, though this converts only at closing. Until then, AXINU is the SPAC shell trading ahead of the combination; the deal remains subject to shareholder, regulatory, and listing approvals.
Facts checked
Terra Quantum is not directly public yet. It has a definitive SPAC agreement with Axiom Intelligence Acquisition Corp 1 (Nasdaq: AXINU), and the combined company is expected to use ticker TQ only after the transaction closes. Until then, AXINU is the publicly traded SPAC shell, not Terra Quantum common stock.
The announced transaction values Terra Quantum at $3.5 billion in equity value and could provide up to $190 million in gross proceeds. The company previously raised roughly $100 million privately; closing remains subject to shareholder, regulatory, and Nasdaq approvals.
Terra Quantum is a Swiss quantum technology company operating across three lines: hybrid quantum-classical algorithms delivered as a service (TQ42 platform), quantum-secure communications, and quantum sensing. Its hybrid approach runs optimization and machine-learning workloads on classical hardware enhanced with quantum methods, serving customers in finance, automotive, and energy.
The company raised roughly $100M privately (Series A rounds, 2020–2023, led by Lakestar) before pursuing a public listing. On May 26, 2026, Terra Quantum signed a definitive business combination agreement with Axiom Intelligence Acquisition Corp 1 (Nasdaq: AXINU) at a $3.5 billion equity valuation, with up to $190 million in gross proceeds expected. Existing shareholders roll 100% of their equity and are expected to hold roughly 92% of the combined company.
The deal is a swift upgrade from a $3.25 billion non-binding letter of intent Terra Quantum had signed with a different SPAC, Mountain Lake Acquisition Corp II, about a month earlier. Closing is targeted for the second half of 2026, subject to shareholder, regulatory, and Nasdaq listing approvals; the combined company is expected to trade under the ticker "TQ" and remain headquartered in St. Gallen.
| Round | Amount | Date | Key Investors | Valuation |

Arqit (ARQQ) is the listed quantum-encryption comparable; D-Wave (QBTS) monetizes quantum optimization. Terra Quantum spans both models.
