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

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

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 grantsreuters.comcm.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 Intelreuters.comcm.asiae.co.kr. The quantum proposals would similarly tie about $10 million of support per company to a U.S. equity investmentreuters.comcm.asiae.co.kr.

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 resultstechi.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 $325ts2.tech. But skeptics point to the high valuation and still-modest growth: with consensus forecasts implying only mid-single-digit gains in coming quarters, the stock may consolidate unless IBM’s bets truly pay off. In short, IBM’s blend of growth potential and safe dividends makes it attractive, but investors should watch closely how the AI strategy executes – as one manager put it, at this “rich” valuation even good results must be very good to move the stock highertipranks.comts2.tech.
