IBM Stock Soars on AI, Cloud and Quantum Momentum

IBM Stock Soars on AI, Cloud and Quantum Momentum

Trump Seeks a Slice of the Quantum Pie: Stocks Rocket as Govt Eyes IonQ, Rigetti, D-Wave Stakes

Trump Administration’s Quantum Push Citing Wall Street Journal sources, U.S. officials are now treating commercial quantum computing as a strategic sector. Under Secretary Gina Raimondo’s reorganized Chips R&D Office, the Commerce Department is reportedly willing to “go deep” in quantum startups – becoming shareholders in exchange for government R&D grants reuters.com cm.asiae.co.kr. This extends Trump’s “government-as-shareholder” industrial policy in tech; for example, in August the administration agreed to convert nearly $9 billion in CHIPS Act grants into a 10% equity stake in Intel reuters.com cm.asiae.co.kr. The quantum proposals would similarly tie about $10 million of support per company to a U.S.

IBM Stock Soars on Quantum Breakthrough and AI Revival – Key Updates (Sept 25, 2025)

IBM Stock Rockets on AI & Quantum Buzz – Analysts Split on What Comes Next

IBM’s long-term story hinges on its success in AI and cloud. If the company can continue delivering above-consensus results (it has a recent streak of ~6% EPS beats) techi.com and land more big AI deals, bulls see plenty of room to run. For example, Goldman Sachs recently raised its target to $310, Wedbush $325 ts2.tech.

In short, IBM’s blend of growth potential and safe dividends makes it attractive, but investors
