Rigetti Stock Slips As Quantum Trade Cools Into Year End What

December 29, 2025, 12:48 ET — Regular session Rigetti Computing shares fell about 2.1% to $21.92 in midday trading on Monday, after closing at $22.38 on Friday. The decline highlights how quickly sentiment can shift in the small group of “pure-play” quantum-computing stocks as the year ends. Profit-taking and thin holiday liquidity have amplified swings in the sector, Investors.com reported. Investors Moves across the group were mixed.

IonQ fell about 2.3% while D-Wave Quantum rose about 0.6%, and Quantum Computing Inc slid about 2.3%. Quantum-computing shares jumped on Dec. 22 without major company news and then sold off over the following three sessions, the Investors.com report said, as some investors locked in gains and others balked at valuations. Investors Quantum computing exploded onto the investment scene in late 2024, igniting a frenzy that propelled pure-play stocks to astronomical heights. Rigetti Computing (RGTI) emerged as one of the biggest beneficiaries, with shares rocketing over 800% in a single month amid breakthrough announcements and surging optimism.

Over the past three years, RGTI has delivered staggering gains of more than 3,200%, and at its peak, the stock was up over 8,200% from historic lows. Early investors have undeniably struck a rich motherlode, turning modest bets into life-changing wealth. Yet for those new to the quantum sector, the ride has been brutal. On Friday, RGTI tumbled almost 9% to close 61% below its October high of $58, erasing much of the year's explosive gains. This pullback mirrors broader pain across quantum stocks like IonQ (IONQ) and D-Wave (QBTS), which have also plunged sharply after similar booms and busts. With the entire sector reeling, investors need to ask: Is the hype surrounding quantum computing finally over – and is RGTI still a buy?

Quantum computing harnesses principles of quantum mechanics, using qubits that can exist in multiple states simultaneously (superposition) and become entangled. Unlike classical bits limited to 0 or 1, this enables quantum systems to explore vast solutions exponentially faster for certain problems. The potential is transformative: faster drug discovery by simulating molecules, optimized financial models, unbreakable encryption breakthroughs, and efficient logistics routing. Quantum could reshape industries from pharmaceuticals to materials science, unlocking solutions classical computers can't touch in reasonable time. Written by Anders Bylund for The Motley Fool-> Rigetti Computing's stock plummeted 42% in November after reporting an 18% revenue decline and ballooning losses of $201 million in Q3 2025.

The company's full-stack approach to quantum computing is impressive, but the technology remains years away from practical commercial advantages over traditional computers. This stock might just be "the next Aurora Cannabis," which would be an unfortunate fate. Shares of quantum computing expert Rigetti Computing (NASDAQ: RGTI) fell 42.2% in November 2025, according to data from S&P Global Market Intelligence. The bearish timeline included a disappointing earnings report, which erased October's 48.6% gain and then some. Rigetti's stock lost 14.2% of its value across the two-month span from Sept. 30 to Nov.

29. Rigetti Computing, Inc. (NASDAQ: RGTI) saw shares decline sharply on Friday, ending the session at $22.38, down $2.13, or 8.7%, after trading in a $22.33–$24.37 range. Late indications suggested a minor rebound to $22.44 in after-hours activity. With U.S. markets closed Saturday, the focus shifts to how liquidity, positioning, and sentiment may influence the next session.

The decline was not driven by company-specific announcements but rather by two key factors: thin, holiday-affected liquidity and a quiet broader market. Fewer institutional traders during the post-Christmas period amplified the impact of smaller trades, creating a “holiday gap” effect where high-beta names like Rigetti can swing wildly. Meanwhile, the broader market remained near record territory, with investors weighing year-end positioning and potential rate cuts. Over the past two days, RGTI’s narrative has been dominated by analyst discussion and market positioning rather than new company filings. Coverage highlighted both bullish and cautious perspectives. Wedbush recently initiated coverage with an Outperform rating and a $35 target, while Mizuho set a $50 target, emphasizing long-term quantum computing potential.

Conversely, some analysts underscored the company’s current unprofitability and uneven revenue trends. The month of November delivered a harsh reality check to the highly speculative quantum computing sector, resulting in a significant “bleed out” for pure-play stocks like IonQ, Inc. (NYSE:IONQ), Rigetti Computing, Inc. (NASDAQ:RGTI), D-Wave Quantum, Inc. (NYSE:QBTS) and Quantum Computing Inc. (NASDAQ:QUBT).

While these stocks saw massive gains throughout much of 2025, November marked a steep correction. By the end of the month: Read Next: Nuclear Stock Meltdown Continues For Oklo, NuScale, Nano The downturn was triggered by a combination of financial and market pressures that exposed the sector's deep structural risks: November's sharp correction confirms that the quantum market remains a high-risk, speculative sector where investors continue to pay for the decades of potential that may lie ahead rather than quarters of profit.
