IBorrowDesk logo

IBorrowDesk

iborrowdesk.com

Best for short interest

Tracks stock-loan availability and borrow fee data as reported by Interactive Brokers (IBKR). Updates roughly every 15 minutes during North American trading hours and hourly elsewhere on weekdays. The data reflects IBKR only and not the wider market. The site is unaffiliated with IBKR; displayed quotes are provided by IEX. A paid Patron tier adds longer history, CSV exports, and more tracking capacity.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
