These bubbles form because investors overestimate how quickly an innovation will be adopted and\/or optimized. In the case of quantum computing, it&#8217;s still very early in its adoption stage and nowhere close to optimizing sales and profits for businesses. Both hallmarks of a bubble are present.<\/p>\n<p>To build on this point, the <a href=\"https:\/\/www.fool.com\/investing\/2025\/12\/17\/1-figure-quantum-computing-bubble-burst-ionq-rgti\/\" class=\"text-cyan-900 hover:text-cyan-800\" rel=\"nofollow noopener\" target=\"_blank\">valuations of quantum computing stocks make little sense<\/a>.
