On June 5, Rigetti Computing fell 5.15% in regular trading, trading at $22.23/share, with trading volume of $151 million. The decline reflects a continuation of profit-taking pressure following the stock's over 50% surge on May 21-22 after the US Commerce Department announced approximately $2 billion in investments across nine quantum computing companies.

Multiple headwinds are converging on the stock. Company executive Rivas David filed Form 144 on May 29, signaling intent to sell 499,328 shares valued at approximately $12.68 million, adding selling pressure. Additionally, Quantinuum began trading on June 4 under the ticker QNT after pricing its IPO at $60 per share to raise approximately $1.68 billion. As a full-stack quantum platform with strong technical credentials, Quantinuum's listing directly dilutes the scarcity premium that had supported Rigetti's valuation as one of few pure-play quantum stocks.

The broader semiconductor sector is also under significant pressure, with Marvell Technology down 7.46%, Micron Technology down 6.44%, Advanced Micro Devices down 5.75%, Broadcom down 4.0%, and NVIDIA down 2.51%, adding systematic downside to the stock.
