What matters

Track what the company has actually announced, the study or asset involved, and the evidence needed to confirm the milestone.

  • Source supports program identity and development context, not a scheduled authorization event; refresh stage and clinical record.
  • Research candidate, not a live market, clinical probability, company equity or access to private shares.

Primary evidence

IND-enabling program — decision date unconfirmed

Company context

Company-authored LinkedIn About explicitly states Type: Privately Held and links arbor.bio. Opened and checked October 31, 2026. This is an undated company self-report, not independent registry proof. The opened 2026 Metagenomi annual report also calls Arbor private.

Potential outcome market

Will Arbor publicly confirm clearance to begin human dosing of ABO-202 in ALS by the market deadline?

This event is research, not a listed market. A market needs a precise question, resolution rules and liquidity before trading opens.
