rigetti stock nasdaq rgti explodes after key quantum milestone

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’s (NASDAQ:RGTI) stock has taken Wall Street by storm, skyrocketing after the company announced a significant breakthrough in quantum computing technology. Investors, analysts, and tech enthusiasts are watching closely as Rigetti’s latest milestone signals a potential new era for commercial quantum computing—and for the company’s prospects in a sector that’s been long on promise but,... Rigetti’s meteoric rise began after it revealed that its latest quantum processor, codenamed "Aspen-M," achieved reliable error rates and algorithm performance surpassing the much-discussed quantum advantage threshold. Quantum advantage refers to the moment when a quantum computer can solve problems faster or more efficiently than the most powerful classical supercomputers. For years, companies and researchers have been racing toward this line, with incremental progress and heavy skepticism from industry observers. The milestone achieved by Rigetti’s Aspen-M chip goes beyond simple error correction.

According to company disclosures, the system now consistently runs quantum algorithms that demonstrate a tangible speedup for certain optimization and simulation problems—some of which are central to logistics, cryptography, drug discovery, and advanced material... This capability opens the door for enterprises and governments to experiment with quantum solutions that, until recently, were largely theoretical. Quantum computing is often described as the "moonshot" of information technology. Unlike classical bits, which store data as 0 or 1, quantum bits (qubits) can exist in multiple states simultaneously due to superposition and entanglement. This makes quantum computers potentially vastly more powerful for certain classes of problems. However, practical, large-scale, and reliable quantum computers have remained elusive, hindered by noise, instability, and extremely high error rates.

Rigetti’s achievement is significant because it marks one of the first credible demonstrations of a mid-scale, gate-based quantum processor reliably surpassing classical machines for targeted tasks. While other tech giants like Google, IBM, and IonQ have claimed various breakthroughs, Rigetti’s progress is unique for its focus on practical, commercially valuable applications rather than abstract benchmarks. Rigetti Computing, Inc. (NASDAQ:RGTI) stock fell Tuesday after the quantum computing firm posted mixed quarterly results and outlined ambitious hardware milestones for the next two years. Shares slipped after revenue came in below expectations, even as losses narrowed and the company strengthened its cash position. Analysts continued to track Rigetti's technology roadmap and expansion strategy, including new international operations in Europe.

NEW YORK, December 30, 2025, 21:48 ET — Market closed Rigetti Computing, Inc. shares closed up 0.7% at $22.41 on Tuesday. About 24.9 million shares changed hands, a level traders flagged as elevated for the stock.

The move mattered because quantum-computing “pure plays” have been a fast-money trade in late December, with sharp rallies followed by quick pullbacks as liquidity thins. Investors.com said the group saw a brief surge on Dec. 22 before a three-day sell-off tied to profit-taking and lighter institutional activity during the holidays. Investors Fresh coverage has kept the sector on traders’ screens even as questions linger over timing for commercial adoption. Barron’s said Jefferies rated Rigetti “Hold” on concerns about reliance on government contracts, noting that 90% of its 2024 revenue came from such work.

Barron’s A Tuesday analysis on Nasdaq.com by Zacks Investment Research compared Rigetti with larger peer IonQ and pointed to the company’s near-term execution risk. “Rigetti remained focused on execution within superconducting quantum hardware,” Zacks writer Urmimala Biswas said, while noting the company’s end-2025 goal for a 100+ qubit “chiplet” system—multiple smaller chips packaged together to scale performance—and a... Zacks also said estimates for Rigetti’s 2026 loss widened to 18 cents a share from 16 cents over the past month and put the stock’s price-to-sales multiple at roughly 220 times. Nasdaq
