Poolside abandoned its $2 billion Series C raise in early April 2026 after CoreWeave exited the anchor-tenant role for Project Horizon. The round targeted $14 billion pre-money valuation with Nvidia NVentures potentially anchoring $1 billion. Only $250 million in soft commitments materialized instead of the full target. Poolside had raised $500 million Series B in October 2024 at $3 billion post-money valuation led by Bain Capital Ventures.
