On June 16, Rigetti Computing fell 5.11% in regular trading, trading at approximately $21.46/share, with turnover of $209 million. The decline came as profit-taking pressure intensified following the prior session's sharp 9.20% rally to $22.91.

On the news front, company executive Rivas David previously filed Form 144 indicating plans to sell approximately 499,000 shares valued at roughly $12.68 million, with this overhang continuing to weigh on sentiment. Additionally, Quantinuum's public listing has been diluting Rigetti's scarcity premium as a pure-play quantum computing stock.

The broader semiconductor sector also traded lower on the session, with Intel down 2.73%, Advanced Micro Devices down 2.73%, and NVIDIA down 1.61%, creating a systematic headwind. The combination of individual stock profit-taking after an overextended rally and sector-wide weakness jointly pressured shares. On the supportive side, the U.S. Department of Commerce's prior announcement of approximately $2 billion in funding for nine quantum computing firms — including roughly $100 million for Rigetti — alongside IBM's multi-billion-dollar quantum investment plan continue to provide medium-term valuation support.
