What the tracker shows

Segmara tracks indicative reference marks for 55 private companies, including OpenAI, Anthropic and Neuralink. Marks are indicative only: they are not live exchange quotes, not offers to sell securities, and not guaranteed transaction prices.

Each mark aggregates private-market signals such as reported secondary transactions and funding rounds, and shows the date it was set. The desk reviews the catalogue against primary sources; the most recent full review was completed on August 23, 2026.

Primary references: SEC private placements investor bulletin, FINRA private placements, SEC EDGAR full-text search.

Is the Segmara pre-IPO tracker free?

Yes. The tracker is free and email-only. No card, no documents, and no brokerage account are required.

Are these live stock prices?

No. Segmara publishes indicative reference marks for private companies with the date each mark was set. Listed or acquired companies appear as research context only. These marks are not live exchange quotes, not offers, and not guaranteed transaction prices.

How often are the indicative marks refreshed?

Each mark shows the date it was set, and the desk reviews the catalogue against primary sources such as SEC filings and reported funding rounds. The most recent full review was completed on August 23, 2026.

Can I buy shares through the tracker?

No. The tracker is research only. Segmara is not a broker-dealer and does not sell, broker, or arrange share purchases.
