According to CoinMeta, Musk was pessimistic about the future of Anthropic in September 2025, but a year later he admitted he was "clearly wrong." Anthropic pays $1.25 billion per month to use SpaceX hardware, with total expenditures expected to reach $15 billion by 2029. Musk called Anthropic an "obvious leader in AI" and praised its model. Although the partnership with SpaceX is not locked in, both parties can terminate it within 90 days.
