QNT Stock Closes Flat On Debut Amid Market Pressure: Retail Turns Bullish, Interest Grows

• QNT stock closed at $60.38, a whisker higher than the company’s IPO price of $60.
• Major quantum stocks were mixed on Thursday, with IONQ gaining nearly 4%.
• Stocktwits sentiment for QNT turned ‘bullish’ from ‘neutral.’

Quantinuum, Inc. shares ended nearly unchanged in their Nasdaq Global Select Market debut on Thursday, with gains capped by a broader technology sell-off following Broadcom’s quarterly report and weighing on sentiment across the sector.

QNT opened at $68 and climbed as much as $71.35 before closing at $60.38, a whisker above the IPO price of $60. Still, retail traders turned upbeat, with several adding the new quantum stock to their watchlists.

Retail Tunes Into QNT

On Stocktwits, the retail sentiment for QNT shifted from ‘bullish’ to ‘neutral,’ and the watcher count increased by about 10x on Thursday. 

“$QNT I’m thinking it was just a bad day to IPO. Bad couple [of] days for most momentum and tech stocks. Same thing happened with Coreweave and now it’s 2-3x IPO price,” said a bullish trader.

Another wrote: “$QNT Very stable and orderly trading today. Wouldn't expect the same urgency as AI-related stocks & IPOs.”

Major quantum stocks were mixed on Thursday. IonQ shares declined 3.8%, while Rigetti shares and D-Wave shares gained about 0.3% each.

The broader technology sector came under pressure after Broadcom issued forecasts that some investors viewed as underwhelming, triggering profit-taking across AI-linked stocks, particularly semiconductor names.

The custom AI chipmaker projected $16 billion in AI chip revenue in the third quarter, much below estimates of $17.2 billion, and kept its fiscal year 2027 outlook unchanged at $100 billion.

The Invesco QQQ Trust Series 1 (QQQ), which tracks Nasdaq stocks, declined 0.5% on Thursday, while the iShares Semiconductor ETF (SOXX) declined 2%.

Quantinuum IPO, Trump Backing

Quantinuum raised $1.68 billion in its IPO, which concluded Wednesday. It sold 28 million shares for $60 each. The offering was increased from 26.5 million shares to a $53-$55-per-share price range and drew more than 20 times the demand for the shares available.

Quantinuum was formed in 2021 by combining Honeywell Quantum Solutions' hardware capabilities with Cambridge Quantum’s software. The company booked a net loss of $136.6 million on net revenue of $5.2 million in 2025, according to its IPO filings.

The IPO timing is notable. Last month, the Donald Trump administration announced a $2 billion package aimed at boosting the U.S. quantum computing industry. Quantinuum is set to receive $100 million, while IBM will get $1 billion, the largest award in the package, to scale its quantum chip foundry.
