Seven AI infrastructure companies file or complete IPOs and major funding rounds in April 2026 to address supply-chain bottlenecks in compute, power, and materials.

Cerebras Systems filed S-1 for IPO on April 17, 2026 (Nasdaq: CBRS planned), with expected raise ~$2 billion at valuation over $35 billion. Fervo Energy filed S-1 on April 17, 2026 (Nasdaq: FRVO planned) with estimated raise ~$250 million. X-energy IPO priced April 23 and began trading April 24, 2026 (Nasdaq: XE), raising ~$1.02 billion at ~$9.1 billion initial market cap. The Elmet Group Co. IPO priced April 22, began trading April 23, 2026 (Nasdaq: ELMT), raising ~$125.5 million at ~$411–438 million market cap. Forge Nano announced definitive SPAC merger on April 21, 2026 with ~$1.6 billion total equity value.

These companies address four supply-side constraints identified by Goldman Sachs as critical to the ~$7.6 TRILLION capital requirement between 2026 and 2031 for global AI infrastructure: Cerebras and Forge Nano tackle silicon replacement cycles and chip manufacturing; X-energy and Fervo Energy provide clean baseload and specialized power for data centers; The Elmet Group supplies critical materials like tungsten and molybdenum for semiconductors and energy; Sivers Semiconductors develops photonics and optical transceivers for high-speed data transmission in AI datacenters.

According to the article, severe physical bottlenecks in the power grid and labor market can elongate construction timelines and stall monetization. Companies offering solutions to these infrastructure constraints are moving to capitalize on the AI build-out by securing funding for the next phase of growth.
