The founders of Fal and Fireworks are in talks to secure new investment that would nearly double the market values they established during funding rounds earlier in 2026. Fal has spoken to investors about raising capital at a $15B valuation, and Fireworks has discussed a figure of $30B.

The surge in fundraising follows a boom in demand for open AI models, which has increased the need for the inference infrastructure provided by these startups. Both companies are seeking to capitalize on this trend to scale their operations and tool ecosystems for AI developers.
