On Thursday (May 21), quantum computing concept stocks surged across the board during U.S. trading hours. D-Wave Quantum (QBTS.US) rose 21.31% to $23.41, leading the sector, with an intraday high of 22.69%; Rigetti Computing (RGTI.US) increased by 20.17% to $20.29, reaching a peak of 21.92% during the day; Quantum Computing Inc. (QUBT.US) climbed 13.39% to $10.84, with an intraday high of 16.32%; IonQ (IONQ.US) rose 8.08% to $56.71, peaking at 8.88%.
On the news front, according to The Wall Street Journal, the Trump administration will provide a total of $2 billion in funding support to nine quantum computing companies and acquire equity in these companies on behalf of the government. Among them, Infleqtion saw a pre-market increase of 25.6%; D-Wave Quantum has officially signed a government cooperation agreement. This marks the first time the U.S. government has systematically intervened in the quantum computing sector through a &#34;subsidy + equity stake&#34; approach, which is viewed by the market as the starting point for a new sector rally driven directly by policy.
The overall sector saw strong buying during the day, with all four major stocks maintaining prices above their opening levels, showing no significant profit-taking: QBTS.US rose from an opening price of $21.85 to a daily high of $23.68; RGTI.US opened at $18.60, reached a high of $20.58, with a fluctuation of about 12%; QUBT.US had an intraday fluctuation of about 8%. The market's reaction to the narrative of &#34;government endorsement + equity binding&#34; was significantly more pronounced than the previous simple &#34;policy expectation,&#34; indicating a shift in quantum computing from thematic speculation to a fundamental reassessment phase
