Deals: AI mega-rounds and quantum breakthroughs ignited markets as mega-merger mania and IPO revivals signaled capital's bold pivot

What’s Happening Right Now?
The markets signaled a decisive AI-fueled breakout, with Anthropic's monster $13B round at a $183B valuation headlining unprecedented venture activity. The quantum computing revolution gained serious momentum as PsiQuantum raised $1B, while mega-deals like Anglo American-Teck's $53B mining merger and Blackstone-KKR's $17B energy infrastructure plays showed institutional capital hunting scale. The IPO window cracked wide open with Klarna's successful $15B debut leading a string of strong public offerings, even as Stripe's $106.7B private buyback signaled premium companies still prefer staying private. Generative AI funding in H1 2025 already surpassed 2024's full-year total, with software and AI companies capturing 45% of all VC funding (Bain & Company, Crunchbase News), while the secondary market exploded 42% compared to H1 2024 (Ropes & Gray LLP, Mondaq). Cross-border dealmaking accelerated with European AI acquisitions and Asian infrastructure plays, pointing to a global capital rotation toward transformative technology and hard assets.
