Chip IPO Radar

Real-time intelligence feed tracking AI chip company IPO filings, secondary valuations, and supply-chain signals — built for investors, procurement leads, and AI infrastructure teams.

What It Does

IPO Filing Tracker — monitors SEC EDGAR for S-1/S-1A filings from AI chip and semiconductor companies in real time
News Intelligence — aggregates AI chip IPO news from Brave Search across targeted queries (Cerebras, Groq, Tenstorrent, supply chain, secondary valuations)
Signal Engine — computes IPO momentum signals from filing activity + news volume, with confidence scores
Watchlist — track specific companies and their IPO stage (pre-IPO → filed → trading)

Data Sources

| Source | URL | What | Refresh | Failure Mode |
|--------|-----|------|---------|--------------|
| SEC EDGAR Full-Text Search | https://efts.sec.gov/LATEST/search-index | S-1/S-1A filings for AI chip/semiconductor companies | Every 6 hours | Shows "data unavailable", logs error |
| Brave Search News API | https://api.search.brave.com/res/v1/news/search | News about chip IPOs, valuations, supply chain | Every 30 minutes | Shows notice, skips without key |

No hardcoded or fabricated data. All filings come from real SEC EDGAR API calls. News comes from Brave Search. If a source is unavailable, the UI displays "data unavailable" — never synthetic values.
