Leases [Abstract]
Leases	Leases The Company leases real estate for office space under operating leases. There are no restrictions or covenants imposed by any of the leases, and none of the Company's leases contain material residual value guarantees. In November 2025, Bakkt executed a Termination of Lease Agreement (the "Lease Termination") for its corporate headquarters office space in Alpharetta, Georgia. The Company recognized income of approximately $7.1 million related to the lease termination, which was recognized in Other (expense) income, net in the consolidated statements of operations. In December 2024, the Company signed a Lease Assignment and Assumption Agreement (the “Lease Assignment”) for its New York office lease, whereby a third-party agreed to assume all the Company’s rights, title and interest in and to the lease, including but not limited to the performance by the third-party of all of the Company’s duties and obligations under the lease.

In January 2025, the Company signed an Assignment and Assumption of Lease with Landlord’s Consent for the New York office lease, which provided the landlord’s consent to the Lease Assignment.
