MARA signs strategic agreement with Starwood to develop its US data center sites

Neutral Impact 4 of 5 m&a Written later

MARA USA Corporation, a MARA subsidiary, entered into a Strategic Agreement with Starwood Capital Group on February 26, 2026. The agreement covers developing, leasing and marketing MARA's existing US bitcoin mining data center properties, outside existing third-party joint ventures, with each property potentially moving into a joint venture where MARA would hold 10% to 50%. The filing gives no dollar value for the deal, and shareholders will depend on how many properties proceed to development.

Key points

  • Covers all of MARA's United States bitcoin mining data center properties other than those held in existing third-party joint ventures.
  • MARA would elect a 10% to 50% interest in each joint venture; Starwood would be managing member and handle day-to-day operations.
  • Each party can decide whether to proceed after a trigger, such as an executable hyperscaler lease; a decision is required 24 months after closing, extendable by 12 months.
  • If Starwood proceeds and MARA does not after a qualifying lease, MARA must sell its rights to the powered land to Starwood.
