Doximity shares surged on Friday after the physician-focused digital platform talked up its artificial intelligence tools, with investors looking past an earnings miss and weaker parts of the quarterly report. The stock jumped as much as 200% in pre-market trade before paring most of the gains.

It was still up about 60%, putting it on track for one of the biggest single-day rallies in its history. The trigger was what its Chief Executive Jeff Tangney said on the company’s earnings call.

6% for what he called Anthropic's best model, Fable 5. Doximity had earlier said its Doximity Ask clinical AI platform outperformed OpenEvidence, Claude Fable 5 and other frontier models in an independent Stanford-Harvard study on clinical AI safety.

Doximity is best known as a digital platform for US medical professionals, offering tools for communication, workflow, telehealth and medical information. The company’s numbers were mixed.

6 million, according to Barron’s. But the earnings miss mattered less after management highlighted AI adoption and performance.
