The IOTA Data Marketplace was launched in November of 2017 with several large companies participating during the initial beta phase. The Marketplace makes it possible to securely store, sell, and access data streams. Users of the IOTA Data Marketplace fall into two categories; buyers and sellers of data. Data is offered for sale at a set amount of IOTA and individuals or corporations can purchase this data.

31 companies launched the IOTA Data Marketplace in November of 2017. The number of companies that participated in the Data Marketplace during January of 2018 totaled 44 entities. The Data Marketplace continued to grow into March of 2018 as the total number of companies participating in the IOTA Data Network has grown to 55 registered participants. Two companies (Microsoft and Schneider Electric) are no longer listed as participants in the IOTA Data Marketplace.

A few things stand out after reviewing the growth of the Data Marketplace:

29 out of the initial 31 participants remain in the Data Marketplace as of March (2018).

13 participants were added to the Marketplace participant list during January (2018).

13 additional participants were added to the IOTA Data Marketplace participant list during March (2018).

Two companies were no longer listed on the participants list as of March (2018). These companies are Microsoft and Schneider Electric.

Here is a table that was created by Haakon from the IOTA Discord that shows the growth of the Data Marketplace over the past 4–5 months:

The IOTA Data Marketplace is still in beta form as of right now but we are hoping that it will be made available to the public soon.
