IonQ: Institutional Accumulation Intensifies Amid Quantinuum IPO Hangover

IonQ shares fell nearly 10% after Quantinuum's IPO and CHIPS Act snub, yet BNP Paribas boosted its stake by 163.5% as revenue and backlog soared.

The quantum computing sector is experiencing a split-screen moment. IonQ shares took a near-10% hit on Friday, closing at €51.21, as investors digested a rival’s public debut. Yet beneath the surface, big money is piling in. BNP Paribas Financial Markets increased its stake by 163.5% to nearly 788,000 shares, a position worth roughly $35 million. That vote of confidence came just days after regulator filings confirmed the move on June 4 – the same day Quantinuum began trading on the Nasdaq.

Quantinuum’s IPO was a study in fleeting euphoria. The company raised $1.68 billion in an offering that was twenty times oversubscribed. Shares opened at $68, a 13% premium to the issue price, before retreating to around $62. The post-IPO cooling prompted a broad reassessment of valuations across the quantum computing space, and IonQ – which competes directly with Quantinuum on trapped-ion technology – bore the brunt.

The pressure wasn’t limited to the IPO aftershock. The U.S. government also distributed roughly $2 billion in CHIPS Act funding, with IBM scooping up $1 billion for its “Anderon” fab and Quantinuum netting $100 million. IonQ came away empty-handed. That sparked a rotation away from smaller specialists toward well-capitalized incumbents, adding to the stock’s weekly turbulence.

But IonQ’s fundamental story remains robust. First-quarter 2026 revenue hit $64.67 million, a 755% surge from a year ago. The backlog of contracted orders swelled to $470 million, up 554%. Management lifted full-year guidance to between $260 million and $270 million – roughly double the prior year’s haul – and the company sits on $3.1 billion in cash.

Much of that firepower is earmarked for the planned acquisition of SkyWater Technology, a $1.8 billion deal that shareholders approved in May. The transaction is expected to close in the second or third quarter of 2026 and would give IonQ full control over its ion-trap chip fabrication. That vertical integration is critical for delivering the 256-qubit system slated for demonstration later this year and for the longer-term target of 8,000 logical qubits by 2028.

Commercial traction is already building. The University of Cambridge became IonQ’s first paying customer for its sixth-generation 256-qubit package, which includes quantum computing, networking, and sensing. Separately, IonQ sold its first Quantum Memory Node to the U.S. Mid-Atlantic Regional Quantum Internet. These wins underpin the raised guidance and give institutional investors tangible evidence of demand.

Institutional ownership is broadening. Vanguard now holds more than 34.7 million shares, while Nomura Asset Management built a new position in the fourth quarter of 2025. On the other side, several insiders have sold millions of dollars’ worth of stock over the past six months. Analysts maintain a consensus “Moderate Buy” rating, with price targets ranging from $35 to $100 and a median of roughly $65.

Technically, the stock sits above its 50-day moving average of €39.70 and its 100-day average of €38.05, but remains about 20% below its 52-week high of €71. The 30-day annualized volatility of 159% underscores the ride. The relative strength index of 52.3 suggests neutral territory – neither overbought nor capitulation.

The next catalysts come quickly. IonQ is scheduled to speak at the Mizuho Global Technology Conference on June 9 and at the Rosenblatt Annual Technology Summit on June 10. Both sessions are expected to shed light on SkyWater integration timing and the deployment schedule for the first 256-qubit systems, which the company targets for the end of the second quarter of 2027. With second-quarter revenue guidance pegged at $65 million to $68 million, the market will soon test whether IonQ’s growth narrative can hold up in an increasingly crowded quantum ecosystem.
