TechStackIPO's IPO Readiness Score is a 0–100 composite built from 12 signals. A score above 90 means a company is in active IPO preparation — either with an S-1 filed, a publicly stated timeline, or both. Grades:
A+ (90–100): S-1 filed or IPO imminent — 12–18 months to listing expected
A (80–89): Advanced preparation — publicly announced timeline or confidential S-1
B (70–79): Pre-preparation — strong fundamentals, no formal IPO process
C (60–69): Growth stage — IPO likely 3+ years out
Why Cerebras Leads the AI Leaderboard
Cerebras filed its S-1 with the SEC on April 17, 2026 — one of two companies in this top 10 with a public S-1 filing (Stripe also filed Feb 14, 2026). Its Wafer Scale Engine AI chip is designed specifically for large language model training, positioning it as a direct competitor to NVIDIA's H100/H200 GPUs. The S-1 filing earns an automatic score boost.
