How long is Anthropic’s lease with SpaceX? Opinions vary.
Elon Musk has clarified the terms of SpaceX's lease with Anthropic, stating it is a short-term agreement rather than a long-term commitment. This contradicts SpaceX's recent S-1 filing, which describes the deal as a three-year lease. The situation raises questions about the accuracy of the information provided by both companies regarding the lease duration.
- ▪Elon Musk stated that SpaceX's lease with Anthropic is a 180-day agreement with a 90-day mutual cancellation notice.
- ▪SpaceX's S-1 filing describes the deal as a three-year agreement with payments through May 2029.
- ▪The discrepancy between Musk's comments and the S-1 filing has led to confusion about the terms of the lease.
