Quantinuum, the Honeywell International-backed quantum computing firm, increased its IPO target to $1.46 billion by expanding share offerings to 26.5 million shares priced between $53-$55. This represents a significant jump from the previous target of approximately 21 million shares at $45-$50 each. At the top of the new range, the company would achieve a market valuation of $14.3 billion.

The quantum computing startup has attracted strong investor demand, with orders exceeding the available shares by a double-digit multiple. Quantinuum stands to benefit from the Trump administration's recent announcement of over $2 billion in funding for quantum computing firms, including a specific allocation of $100 million to the company, in exchange for an equity stake.

Quantinuum develops powerful quantum computers capable of solving complex tasks beyond traditional processors, with applications spanning chemistry, machine learning, cybersecurity, finance, and drug discovery. The shares are scheduled to begin trading on the Nasdaq Global Market under the symbol QNT following Wednesday's pricing.
