After the recent price rally in quantum stocks, an insider sale at D-Wave Quantum raises new questions. What this means for investors.
• Grants under the CHIPS Act recently provided strong tailwind for quantum stocks
• Insider selling of around $437,000 caused disillusionment at D-Wave Quantum after trading
• Shares are already pricing in a lot of future fantasy
After the stock market party for quantum stocks: disillusionment in after-hours trading
Quantum stocks, including D-Wave Quantum shares, had been trading in a frenzy over the past week. After the prospect of financial subsidies as part of the “CHIPS and Science Act,” investors jumped at the chance.
D-Wave Quantum has increased by more than 60 percent since last Wednesday. Most recently on Friday there was an increase of 14.22 percent to $29.40. After trading, however, the mood at D-Wave changed: the share fell by 2.62 percent to $28.63.
Industry colleagues Rigetti Computing and IonQ also benefited from the buying mood in the sector and entered the weekend with significant gains of 19.87 percent to $26.42 and 8.07 percent to $63.64, respectively. Here too, however, losses were seen in after-hours trading.
Insider selling raises questions
The background to the apparently rapid change in mood at D-Wave Quantum was a transaction by Sophie Ames, Executive Vice President and Chief Human Resources of the Palo Alto-based company. As Benzinga reports, Ames disclosed the sale of 23,025 shares. The volume was around $437,000. The transactions were carried out on May 20th at a weighted average price of approximately $18.98.
According to Benzinga, the sale was made under a pre-agreed Rule 10b5-1 trading plan that was adopted in June 2025 and amended in September 2025. Following the sale, Ames continued to hold 596,803 shares, including 543,750 unvested restricted stock units.
What does this mean for investors now?
An insider sale shouldn’t automatically be viewed as a warning sign, especially since in this case, according to Benzinga, it occurred via a predetermined trading plan. Nevertheless, the timing of the disclosure certainly raises questions: the share is in the spotlight after a massive rally, the valuation is increasingly pricing in future fantasy, while investors are still waiting for concrete operational confirmation.
Those who trade the stock rely less on the current state of business than on the assumption that government funding, technological advances and commercial demand will soon converge more closely. But the after-market setback also shows that the fall height for D-Wave Quantum has increased. It is therefore crucial for investors whether the share can support its momentum story with reliable progress or whether profit-taking will initially dominate after the insider news.
