Resolution criteria

• Yes if a U.S. SEC Form 4 lists Elon Musk (including via the Elon Musk Revocable Trust) as the reporting person and shows purchases of Tesla common stock with Transaction Code “P” dated on or before 2025-09-18. Primary source: Musk’s Form 4 filings on EDGAR. (sec.gov)

• No if no such Form 4 reports any Musk purchases dated on or before 2025-09-18.

• Exclusions: company share repurchases by Tesla, option exercises (Code “M”), awards/RSUs (Code “A”), gifts (Code “G”), or derivative-only activity do not count. Resolution relies on the Form 4 transaction date, not the filing date. EDGAR issuer page may be used to verify additional or amended filings. (sec.gov)

Background

• Elon Musk filed a Form 4 on 2025-09-15 disclosing open‑market purchases on 2025-09-12 totaling about 2.57M TSLA shares at $372–$396 per share ($1B). This was his first open‑market buy since 2020, widely reported by major outlets. (sec.gov)

Considerations

• Because Form 4s can post up to two business days after a trade, this market will resolve based on the transaction date shown on the Form 4 even if the filing appears after 2025-09-18. The specific Sep 12, 2025 purchases disclosed by Musk’s Form 4 meet the date condition. (sec.gov)
