$2 billion to $5 billion valuations are being discussed for Quantum Art and Classiq in advanced Wall Street SPAC talks, with Quantum Art reportedly further along and potentially listing before end-2026.
About 30 SPACs are searching for quantum targets, including an Israeli vehicle that recently raised $172 million, as quantum startups chase faster access to capital for costly, largely pre-revenue development.
Quantum Art has raised about $200 million in total to build trapped-ion hardware, while Classiq has raised about $200 million for software used with partners and customers including Nvidia, Microsoft, AWS, BMW and Citi.
Five quantum startups have already gone public via SPACs since the start of 2026 and another five are in advanced talks, leaving listed quantum companies with a combined valuation near $70 billion.
Israel now hosts roughly 20 of the world’s 270 quantum companies, but the boom carries valuation risk because practical fault-tolerant systems remain unproven and some public peers trade at more than 100 times revenue.
