Claude’s Fable 5 just solved an 87-year-old math problem, and it matters for bitcoin
Claude Fabel 5 disproved the Jacobian conjecture over the weekend, landing days after the capabilities of China’s Kimi AI became the biggest force moving bitcoin markets.

Summary
- An Anthropic AI model, Claude Fable 5, helped disprove the 87-year-old Jacobian conjecture, a famous open problem in mathematics dating to 1939.
- The model produced a concrete counterexample that mathematicians could verify by hand within a day, showing that a certain kind of mathematical “machine” can pass standard checks yet still not be reversible.
- The breakthrough underscores how rapidly advancing AI capabilities are drawing speculative capital and attention away from crypto and toward computing power, chips and model builders.
That an AI produced original mathematics of this difficulty is the kind of capability leap that now moves markets, crypto among them. Bitcoin has spent months trading on a narrative about artificial intelligence, moving with chipmakers and memory stocks rather than any catalyst of its own.
It fell hard last Friday when Chinese lab Moonshot AI released a model that rattled the semiconductor industry, and it recovered this week as those stocks bounced.
Part of that link is direct. Bitcoin’s biggest holders, its miners, have rebuilt themselves into AI data-center operators, so their fortunes now rise and fall with demand for computing power.
