In the first half of 2026, VC capital reached $412.7 bn, surpassing the previous year’s total of $319.2 bn and underscoring investors’ strategic focus on AI. Mega‑deals—defined as rounds of $100 mn or more—account for 87.5% of this funding.

Strategic Takeaways and Outlook

■AI‑centric mega‑deals reinforce a “few large players” model for scalability and market dominance.

■Companies favor tender‑offer exits over IPOs, providing liquidity while avoiding public market volatility.

■Heightened market volatility prompts some decacorns to postpone IPO plans, emphasizing flexible capital management.
