What was claimed

'Just asked Grok @Bot about SpaceX stock price. It replied that it's not IPOed yet. So I corrected it. Still has room for improvement.'

@Jasoncheung on X. Original post

What we found

Yes, SpaceX is public: Class A shares trade on Nasdaq as SPCX since its June 2026 IPO (priced at $135.00 a share). At 09:12 UTC+8 on Oct 22 the US market was closed; the last close (Oct 21) was $159.31, up 7.79% on the day, and after-hours trading ended at $156.70. Three quote sources agreed to the cent. An agent answering from training data alone would say not public yet, which is what the post describes.

Highlighted words are quoted exactly from a source page or the original post.

How we checked it

SEC EDGAR (ticker SPCX, exchange Nasdaq, periodic reports, the 424B4 prospectus) for the listing; Nasdaq, CNBC and Google Finance for the price (Nasdaq and CNBC both carry Nasdaq-sourced data, Google is a separate display).

What the agent did

  1. SEC company_tickers.json: SPACE EXPLORATION TECHNOLOGIES CORP = SPCX (CIK 1181412)
  2. EDGAR filing history: IPO prospectus (424B4) filed 2026-06-12, 10-Q filed 2026-08-04, 8-K 2026-10-20
  3. Prospectus: IPO at $135.00 a share, listed on Nasdaq and Nasdaq Texas as SPCX
  4. Nasdaq quote API: $159.31 last sale, market closed
  5. CNBC quote: $159.31 close, $156.70 after hours
  6. Google Finance page: same two prices
  7. Yahoo Finance API: 429 (rate limited); Stooq: 404

Sites and APIs touched: sec.gov, data.sec.gov, api.nasdaq.com, quote.cnbc.com, google.com/finance, query1.finance.yahoo.com, stooq.com.

Where it went wrong

  • Answering from memory gets this wrong: the IPO is newer than many models' training data. Ask the agent to check a live source.
  • Two of five quote sources failed (Yahoo 429 rate limit, Stooq 404).
  • Outside US market hours 'right now' means the last close or after-hours price; the answer should say which.

Try it yourself

Exact prompt we used
What is SpaceX's stock price right now? Is it publicly traded, on which exchange and under what ticker?

Lowest-access way to try it

L0. Ask the agent to confirm the ticker in an official source (the SEC or the exchange) and to give the time of the quote.

Looked SpaceX up in SEC EDGAR (ticker list, filing history, the IPO prospectus) instead of trusting memory, then read the price from three quote sources and noted that the market was closed.
