Factual Economics and markets

Calibra is a Facebook subsidiary and the first member of Libra.

Unresolvable The public record could not settle it.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

Judged as of 18 June 2019. True: Facebook's announcements and the Libra white paper or launch materials of that date show that Calibra was a Facebook subsidiary (the claim's description of Calibra as a 'crypto-currency' is not part of the proposition tested) and was described as the first, or a founding, member of the Libra Association or network. Mostly true: Calibra was a Facebook subsidiary and a founding member of Libra, but was one of several founding members announced at the same time, rather than clearly 'the first'. Mixed: only one of the two parts (subsidiary; first member) holds. Mostly false: Calibra was related to Facebook but was not a subsidiary, and its membership is misdescribed. False: Calibra was neither a Facebook subsidiary nor a Libra member.

Evidence (3)

  1. E1 Coming in 2020: Calibra Facebook (about.fb.com newsroom) · 18 June 2019 Own record

    “Today we’re sharing plans for Calibra, a newly formed Facebook subsidiary whose goal is to provide financial services that will let people access and participate in the Libra network.”
  2. E2 Facebook Unveils Libra Cryptocurrency, Targeting 1.7 Billion Unbanked CoinDesk · 18 June 2019

    “The Libra Association's group of 28 founding members includes Visa, Mastercard, PayPal, Uber, Lyft, Coinbase and others.”
  3. E3 1 July 17, 2019 Testimony of David Marcus U.S. House Committee on Financial Services (hosted on congress.gov) · 17 July 2019 Own record

    “Technology and marketplaces: Booking Holdings, eBay, Facebook/Calibra, Farfetch, Lyft,”

Reasoning

Facebook's announcement (E1) describes Calibra as a newly formed Facebook subsidiary, but none of the evidence items shows that Calibra was a founding or first member of Libra: E2 does not name Calibra among the 28 founding members, and the quoted line from E3 lists "Facebook/Calibra" under a technology and marketplaces heading without saying the list is of members. The membership part of the criteria is therefore not settled.
