Performance Summary: Quantum Companies in June 2026
| Ticker | Company Name | 01/06/2026 | 30/06/2026 | Difference | Percentage | Remark |
| IONQ | IONQ Inc | 72,07 | 53,26 | -18,81 | -26,10% | The stock saw high volatility, dipping mid-month due to inflation data and geopolitical concerns, but rebounded. Analysts noted that it continues to trade at a massive premium ($65.3x forward sales$) relative to its fundamentals, driven strictly by its long-term platform potential. |
| RGTI | Rigetti Computing Inc | 25,54 | 19,32 | -6,22 | -24,35% | Moved sideways to slightly down (-12.3% year-to-date). However, analysts highlighted its massive relative advantage of having $569M in cash with zero debt to execute its 3-year "quantum advantage" roadmap, contrasting with other cash-strapped pure-plays. |
| QBTS | D-Wave Quantum Inc | 30,14 | 23,99 | -6,15 | -20,40% | Spiked over 12% on June 15 after Mizuho lifted its target price to $35, praising its logical-qubit roadmap up to 2030 and strong business pipeline. However, standard investor caution on near-term revenue conversion led to an uneven end of the month. |
| QTUM | 31 | 159,75 | 165,38 | 5,63 | 3,52% | |
| HQ | Horizon Quantum Holdings Ltd | 13,2 | 27,76 | 14,56 | 110,30% | Retained heavy upside momentum following its June expansion plans into Europe (Ireland) and the overall positive sentiment trickling down from global government funding directives. |
| QUBT | Quantum Computing Inc | 11,96 | 9,7 | -2,26 | -18,90% | Dropped over 21% over the course of June, correcting from $11.96 down to the low $9s. This drop was a broad technical pullback on speculative hardware equities, despite completing a major operational milestone by acquiring NHanced Semiconductors. |
| IQMX | Real Asset Acquisition Corp | 11,35 | 10,8 | -0,55 | -4,85% | Merged successfully with Real Asset Acquisition Corp at the end of June. The price stabilization and volume surges were entirely driven by investor excitement for its debut on the main Nasdaq board. |
| IBM | IBM Common Stock | 297,8 | 281,21 | -16,59 | -5,57% | Stable performance with slight upward traction. Benefited heavily from defensive institutional money leaving riskier quantum pure-plays and seeking established tech companies with diversified commercial quantum enterprise platforms. |
| GOOGL | Alphabet Inc Class A | 380,34 | 357,37 | -22,97 | -6,04% | Driven upwards by massive systemic AI tailwinds alongside continuous updates on its quantum-fault tolerance research labs, offsetting any macro inflationary jitters |
| FJTSY | Fujitsu Ltd | 21,4 | 19,87 | -1,53 | -7,15% | Price remained resilient on the Tokyo Stock Exchange due to the formal deployment of their asset-management algorithm research partnerships with major entities like Daiichi Life Group. |
| NVDA | NVIDIA Corp | 211,14 | 200,09 | -11,05 | -5,23% | |
| CVE:ONE | 01 Quantum Inc | 0,58 | 0,5 | -0,08 | -13,79% | Volatile micro-cap activity; highly dependent on short-term retail momentum regarding their portable hardware security modules. |
| BABA | Alibaba Group Holding Ltd - ADR | 124,22 | 95,98 | -28,24 | -22,73% | Stock movements were largely dictated by macro Chinese regulatory cycles and regional hardware stimulus incentives, coupled with domestic sovereign cloud developments. |
| BIDU | Baidu Inc | 135,31 | 114,29 | -21,02 | -15,53% | |
| ATO | Atmos Energy Corp | 169,13 | 172,27 | 3,14 | 1,86% | Movements were completely disconnected from the quantum sector; stock actions followed standard utility defense buying (Atmos) and aerospace/defense logistics trends (AAR). |
| AIR | AAR Corp | 112,62 | 142,93 | 30,31 | 26,91% | |
| ACN | Accenture Plc | 187,07 | 124,44 | -62,63 | -33,48% | |
| QNC | Quantum eMotion Corp | 3,24 | 3,12 | -0,12 | -3,70% | Volatile micro-cap activity; highly dependent on short-term retail momentum regarding their portable hardware security modules. |
