On May 21, Infleqtion rose 8.44% in after-hours trading, trading at $15.79 USD/share, with trading volume of $16.46 million.

On the news front, the rally was driven by the company's announcement that it signed a $100 million letter of intent with the US Department of Commerce, aimed at accelerating and consolidating US global leadership in quantum computing. The agreement is part of a broader $2 billion CHIPS Act allocation directed at nine quantum computing firms, with IBM receiving the largest share of $1 billion, GlobalFoundries receiving $375 million, and companies including D-Wave Quantum, Rigetti Computing, and Infleqtion each receiving up to $100 million.

The catalyst triggered a sector-wide rally during regular trading, with D-Wave Quantum and Rigetti Computing surging over 22%, IonQ rising over 11%, and Infleqtion itself climbing as much as 44% intraday. The after-hours continuation reflects sustained momentum from the policy-driven catalyst. Additionally, the stock had previously corrected over 25% across three consecutive sessions following its Q1 earnings release, creating oversold rebound conditions that amplified the upside response.
