Quantinuum Inc. is trading 6.3% up at $66.70, extending a sharp post-IPO rally after Hewlett Packard Enterprise highlighted the company as a key partner in a new hybrid quantum computing initiative.

  • The upward move follows two sessions of significant gains, including a 15.4% jump in pre-market trading on June 18 as the partnership fuels renewed investor enthusiasm.
  • Investors are currently weighing the company's long-term growth potential against its relatively small $31 million revenue base and lofty market valuation.
