Space Exploration Technologies Corp. Class A Common StockAnthropic's call to slow AI development threatens its $45B compute-rental deal, which can be exited on 90 days' notice.

Anthropic chief executive Dario Amodei published a blog post calling for a slowdown in the pace of artificial intelligence development, warning the technology is progressing so fast that control could be lost, and citing recent cybersecurity events as evidence. The warning puts pressure on SpaceX, which in May signed a deal to rent computing capacity to Anthropic that is expected to bring in $1.25 billion per month through May 2029, worth roughly $45 billion overall. SpaceX has also agreed to lease approximately $920 million in capacity to Alphabet from October 2026 to June 2029, and roughly $150 million worth of capacity per month to start-up Reflection AI through 2029. SpaceX chief financial officer Bret Johnsen has said the company's AI business could reach a $100 billion annual revenue run rate by the end of 2026, and Elon Musk has said the AI segment could propel SpaceX to $1 trillion in annual revenue as soon as 2030. However, most customers can end their infrastructure agreements with 90 days' notice, so if Anthropic needs less capacity because of its plan to pace AI development, it could exit its contract far earlier than anticipated. SpaceX generated $7.8 billion in total revenue in the second quarter of 2026, up 92% year over year, with $2.561 billion from AI, $4.291 billion from connectivity, and $0.962 billion from space. Based on trailing 12-month revenue of $23 billion, SpaceX trades at a price-to-sales ratio of 87.3, 14 times the Nasdaq-100's 6.1, and Wall Street expects total revenue of $106.5 billion in 2027, a forward price-to-sales ratio of 18.8. SpaceX stock is already down 34% from its all-time high.
