## Plain-language explanation

Prime numbers follow a mysterious pattern. Claude did not solve the famous Riemann Hypothesis, but its researchers say it raised the minimum known share of certain zeros lying on the crucial line from 41.6% to 67.2%.

## Research contribution

An unreleased Claude system improved a lower bound for the proportion of nontrivial zeros of the Riemann zeta function on the critical line. Anthropic reports internal verification, external expert examination and a formal proof artifact.

## Academic interpretation

For ζ(s), the Riemann Hypothesis asserts that every nontrivial zero has real part 1/2. A positive-proportion theorem gives a lower bound on zeros lying on that line; increasing the proven fraction is distinct from establishing 100%. The announced 67.2% bound and its assumptions must be read with the paper and formalization.

## Implications

Advances analytic number theory and showcases AI assistance in delicate estimates, without resolving the distribution of all nontrivial zeros.

## Caveat

Do not label this a proof of the Riemann Hypothesis. Third-party examination is reported, not independently re-performed by this site.
