- Jul 7, 2026NA Startup Funding Shatters Records in H1 2026North American startups raised $392 billion in the first half of 2026, an all-time record, with roughly 80% of Q2 investment dollars flowing to AI-focused companies as capital concentrates in an ever-smaller set of megadeals.→
- Jun 29, 2026SeeQC Files S-1 for Nasdaq IPO to Fund Digital Quantum Computing ChipsSeeQC, which builds digital quantum-computing infrastructure, filed a Form S-1 to list on the Nasdaq Global Market under ticker 'SEQC,' paired with a $65 million PIPE financing that values the combined entity at roughly $1 billion. The company integrates superconducting single-flux-quantum logic with cryogenic CMOS to shrink the wiring and heat load of quantum systems -- reporting $4.2 million in 2025 revenue against a $12.2 million net loss.→
- Jun 29, 2026SeeQC Files S-1 as Quantum Computing IPO Wave Widens Beyond IonQ and D-WaveDigital quantum computing firm SeeQC filed an S-1 on June 29, becoming one of the first pure-play quantum specialists to file since the 2021 SPAC rush. SeeQC's superconducting chips integrate quantum bits directly with classical control electronics, targeting scalable systems that competitors say require room-scale cabinets today.→
