Lovable rockets to $6.6B valuation with $330M Series B, underscoring AI-native software’s grip on late‑stage capital

TOP 3 STORIES:

1. Lovable raises $330M Series B at $6.6B valuation to scale AI-native coding globally
Swedish AI coding platform Lovable closed a $330 million Series B led by CapitalG and Menlo Ventures, tripling its valuation in five months to $6.6 billion, with participation from Khosla Ventures, Salesforce Ventures, and Databricks Ventures.[5][1] For founders, this signals that investors are still eager to back opinionated, AI-native vertical platforms at growth stages—but expectations around rapid global go-to-market and infrastructure partnerships will be very high.[5][7]

2. OpenAI targets up to $100B raise at ~$830B valuation, testing the ceiling of AI investor appetite
OpenAI is reportedly seeking to raise as much as $100 billion, potentially valuing the company at around $830 billion, in a round expected to close no earlier than end of Q1 next year.[6][3] This proposed raise further concentrates capital at the very top of the AI stack, meaning early-stage founders should either position clearly as ecosystem complements (infrastructure, safety, domain-specific apps) or deliberately differentiate away from direct platform risk.[6]

3. 2025 data: AI funding dominates with 58% of dollars going into $500M+ megarounds
New year-end data show that in AI, 58% of funding in 2025 went into megarounds of $500M+, with VC firms still leading about 75% of analyzed deals of $1M+ despite fewer billion‑dollar rounds.[4] For entrepreneurs, this creates a barbell market: massive checks for a few AI winners and disciplined, milestone-driven rounds for everyone else—so sharpening capital efficiency and clear paths to revenue is increasingly non‑negotiable.[4]

Flash Insight:
AI continues to dominate capital flows, with Lovable’s leap to a $6.6B valuation and OpenAI’s prospective $100B round illustrating how quickly value accrues to perceived category leaders in AI-native tooling and platforms.[5][6] At the same time, funding analytics show a structurally barbelled environment, where mid-stage rounds are squeezed while very large megarounds and lean early-stage bets thrive.[4] Founders should respond by building products that either tightly integrate into the emerging AI “super platforms” or serve resilient, regulated, or niche markets where differentiation, not raw scale, is the primary moat.
