Quantinuum IPO Targets $12.7B Valuation, Plans to Raise Up to $1.05B

This IPO gives retail investors their first real shot at direct exposure to a scaled quantum computing company — a space previously locked behind private funding rounds and conglomerate balance sheets. Honeywell, which retains a majority stake, stands to see its own valuation recalibrated as the market prices Quantinuum independently. Broader quantum and deep-tech ETFs may also see inflows as the listing draws attention to the sector.

IPO pricing date: expected imminently given terms are already set. Post-listing lock-up expiry: typically 180 days after IPO date, when insiders can first sell shares. Watch for Honeywell's next earnings call for commentary on retained stake and any valuation impact.
