Daily stocks & crypto headlines, free to your inbox By continuing, I agree to the Market Data Terms of Service and Privacy Statement Shares of Rigetti Computing (RGTI) garnered retail investor interest on Friday as the community debated its missed deadline for delivering a 100+ qubit chiplet-based system by the end of 2025. Rigetti had said in July that it remains on track to release its 100+ qubit chiplet-based system at 99.5% median two-qubit gate fidelity before the end of 2025. However, walking into 2026, there has been no announcement from the company of the said system. To further concerns and drag down investor sentiment, the company announced in a filing with the Securities and Exchange Commission that its director Fitzgerald Alissa sold nearly 60,000 shares of the company.

On Stocktwits, retail sentiment around RGTI stayed within the ‘bullish’ territory, accompanied by ‘normal’ message volume. A Stocktwits user highlighted the insider share sale on Friday as a sign of the company’s downfall. 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. Rigetti Computing Inc. (NASDAQ:RGTI) just flipped the switch on its biggest quantum breakthrough yet – and for once, Wall Street didn't sleep through it. The company's reveal of a 36-qubit modular quantum system with record-setting fidelity has investors scrambling, sending RGTI stock up 14.5% by 10 a.m. ET.

Quantum might still be years from going mainstream, but Rigetti's stock is having its moment right now. Rigetti has built the largest modular quantum computer yet by linking together four 9-qubit chips to create a 36-qubit system. But it's not just about size—the company also cut its error rate in half, reaching 99.5% accuracy in how its qubits work together. That's a major step toward making quantum computers more reliable. What makes this even more impressive is that Rigetti isn't just talking about modular quantum design – it's actually delivering. With real data, real performance and a clear path to building a 100+ qubit system by the end of the year, Rigetti is turning big quantum ideas into working technology.

Rigetti Computing, a pure-play quantum hardware and software firm, recently achieved a key technical milestone and is now pushing toward early commercialization. In mid-2025, Rigetti announced general availability of its 36-qubit multi-chip quantum computer and reported a 99.5% median two-qubit gate fidelity on that system. These developments come amid mounting investor expectations for quantum computing’s transition from laboratory to market. Financially, Rigetti bolstered its balance sheet via a $350 million equity offering in 2025 that strengthened its cash reserves.

Meanwhile, revenue remains modest and volatile, reflecting the early stage of quantum technology. In this climate, the company is navigating both technical challenges and market pressures as it seeks to turn breakthroughs into stable business outcomes. Rigetti’s near-term technical agenda centers on scaling qubit count, improving error rates, and advancing modular architectures. The company has set a target to grow beyond its 36-qubit multi-chip system toward a 100+ qubit architecture later in 2025 and further toward the 1,000+ qubit range over several years. Achieving high fidelity and reducing noise remain critical, Rigetti’s recent milestone of 99.5% median two-qubit gate fidelity on its modular 36-qubit platform marked a roughly twofold improvement in error rate versus prior designs.
