This adds to the decline in Block's stock price, which has fallen 18.24% so far through 2025.
Despite the sharp market reaction, certain metrics in Block's third-quarter results showed strong growth for the company.

Block Bitcoin Mining Business
Block Chief Financial Officer Amrita Ahuja said on a conference call with investors that the company's Bitcoin mining arm, Proto, is starting to see results.
“We generated the first revenue and planted the seeds of what could be the next major ecosystem,” Ahuja said. “We have monetized Proto’s innovations in hardware and software through hardware sales across ASICs, mining hashboards, and full mining rigs that provide many of the key advanced components for mining Bitcoin.”
Proto was launched in November 2024, but the deployment of the first mining rig was not announced until August. Ahuja said third-quarter revenue was “modest,” but the company is “aggressively pursuing a robust pipeline into 2026.”
