NEW YORK, December 31, 2025, 20:15 ET — Market closed
- IonQ shares closed down 0.9% at $44.87.
- IonQ said it finalized a South Korea delivery agreement for its Tempo 100 quantum system.
- U.S. markets are closed Jan. 1 for New Year’s Day and reopen Jan. 2.
IonQ Inc shares fell 0.9% to $44.87 at Wednesday’s close, after hitting a session low of $44.68 and a high of $46.42. Quantum-computing peers Rigetti Computing, D-Wave Quantum and Quantum Computing Inc also ended lower, and about 11.4 million IonQ shares changed hands.
The group has traded like a high-beta corner of tech, where sentiment shifts can move prices quickly even without major earnings catalysts. For many investors, customer wins and system-delivery milestones remain the clearest near-term signals of demand.
IonQ’s latest headline was a South Korea delivery agreement as the company pushes deeper into installed systems. In a small, early-stage market, that kind of announcement can matter as much for credibility as for near-term revenue.
IonQ said on Monday it finalized an agreement to deliver a 100-qubit Tempo 100 system to South Korea’s Korea Institute of Science and Technology Information (KISTI). “This is a defining moment for both IonQ and South Korea,” Chief Executive Niccolo de Masi said in a statement. A qubit is the basic unit of quantum information, and IonQ did not disclose the contract’s financial terms. 1
The company said the system will be integrated with KISTI-6 (“HANGANG”), the country’s largest high-performance computing cluster — the kind of conventional supercomputer used for heavy scientific computing — in an on-site hybrid setup that links quantum and classical machines.
For investors, the next questions are timing and how quickly a delivered system turns into recurring usage and follow-on orders. Without pricing and delivery detail, traders often wait for later disclosures or management commentary.
IonQ’s shares can also move in sympathy with the rest of the quantum-computing group, where momentum has tended to spill across names. That dynamic was visible again on Wednesday as the sector drifted lower into the holiday break.
Before the next session, U.S. stock markets will be closed on Thursday for New Year’s Day and reopen on Friday, January 2, according to the New York Stock Exchange holiday calendar. 2
Friday’s early economic calendar includes S&P Global’s final U.S. manufacturing PMI for December at 9:45 a.m. ET, a survey of purchasing managers that can shift rate and growth expectations.
The Institute for Supply Management is scheduled to publish its December manufacturing PMI on Monday, January 5, at 10:00 a.m. ET; readings below 50 indicate contraction. 3
On the company front, IonQ has not announced a date for its next earnings report; MarketBeat’s calendar lists an estimated Feb. 25 release. Investors will look for any update on system-delivery timelines and demand into 2026. 4
After the holiday, traders will watch whether IonQ can hold above Wednesday’s low and push back toward the session highs, with liquidity typically thinner around the turn of the year.
IonQ, based in College Park, Maryland, sells access to its quantum computers through major cloud platforms, including services run by Amazon, Microsoft and Google, according to a Reuters company profile. It is competing with quantum hardware developers such as Rigetti and D-Wave as customers test early commercial use cases. 5
