## IPO Signal Research — Pre-IPO Signal → Outcome Correlations
Source: https://www.techstackipo.com/research/ipo-signals
Dataset: 27 historical tech IPOs (2019–2026) | 216 pre-IPO signals | 114 correlations computed | 53 statistically significant (p≤0.05)

Key findings:
- Media Hype Score ≥80 correlates with average +69.4% first-day return (n=9)
- Valuation trajectory 2–4x in 12 months correlates with average +59.3% first-day return
- Fast funding velocity (rounds within 6 months of IPO) correlates with average +51.7% first-day return
- Funding velocity is the strongest predictor of 3-month post-IPO return (Pearson r=0.63, p<0.001)
- Large first-day pops do NOT predict 1-year performance — correlation is negative
  Example: Snowflake +112% day-1 → +1.4% year-1 return
- Notable historical IPOs in dataset: Arm (+24.7% day-1), Instacart (+12.3%), Reddit (+48.4%),
  Airbnb (+113%), DoorDash (+86%), Rivian (+29%), Palantir, GitLab, Affirm, Rubrik, Klaviyo

Signal types tracked: media hype, funding velocity, revenue growth, valuation trajectory,
underwriter tier, auditor quality, employee count, S-1-to-pricing days

## Data Methodology
- Sources: SEC EDGAR filings (confidence 1.0), company press releases (0.9), Bloomberg/Reuters/WSJ (0.8), secondary media (0.6), estimates (0.4)
- Update frequency: Weekly intelligence sweeps (Monday) + daily SEC monitoring
- IPO status rule: ONLY marked Pre-IPO when S-1 filed or publicly announced — never inferred from funding stage
- Valuation: Latest post-money valuation from equity rounds; secondary market pricing noted separately
