Official exchange data is reported twice a month. That's ancient history. Access real-time Securities Lending data, including Cost to Borrow (CTB), Utilization Rates, and Short Interest as a % of Float. Know exactly when a "Crowded Short" is about to explode.
Don't Get Caught Offside. Whether you are looking for a short candidate or protecting a long position, you need to know the "Cost of Crowding."
Exchange-reported short interest is lagged by 15 days. We bridge the gap. By aggregating intraday lending data from global Prime Brokers and Custodians, we provide a live proxy for Utilization Rates and Shares Available to Borrow. See the supply dry up before the price spikes.
We combine Short % of Float, Days to Cover, and Cost to Borrow into a single, proprietary 0-100 Squeeze Score. A score >80 signals a "Powder Keg" scenario where minor buying pressure could trigger a massive cascade of forced covering.
Is the stock "Hard to Borrow" (HTB)? We track the annualized fee (CTB) required to short the stock. A spiking CTB is the earliest warning sign of aggressive institutional shorting or a drying lending pool—often a precursor to extreme volatility.

} utilization_rate : The percentage of lendable shares currently out on loan. At 98.5%, the supply is effectively exhausted. cost_to_borrow_avg (CTB)The annualized interest rate paid to borrow the stock. A high CTB (e.g., >20%) indicates "Hard to Borrow" status, meaning only high-conviction shorts are staying in the trade. days_to_cover : Calculated as Shares Short / Average Daily Volume. It represents how many days of buying it would take for all shorts to close their positions. squeeze_score Our proprietary composite metric.

By regulation (FINRA/SEC), official short interest is reported twice a month (settlement dates on the 15th and last day of the month). We publish this official data immediately upon release (approx. 7 business days lag).
It comes from the Securities Lending Market. We aggregate anonymized inventory feeds from major Prime Brokers and Agent Lenders. This gives us a statistical estimate of "Utilization" and "Cost to Borrow" in real-time, bridging the 2-week gap between official exchange reports.
"Naked" shorting is illegal and not explicitly reported. However, our "Fail to Deliver" (FTD) dataset (available via the Compliance endpoint) highlights instances where trades failed to settle, which is often used by researchers as a proxy for naked shorting activity.
cost_to_borrow_max so much higher than the average?In illiquid or hard-to-borrow stocks, specific brokers may charge exorbitant rates to desperate borrowers. The "Max" rate shows you the extreme price of liquidity in the market, often signaling panic covering.
This is a critical distinction for modeling. Short Interest is the total number of open short positions held overnight (Stock). Short Volume is the number of shares sold short intraday (Flow), which includes market maker hedging. Our API provides both, allowing you to correlate daily selling pressure (Volume) with long-term structural crowding (Interest).
Yes. Securities lending is a global market. We track borrow rates (CTB) and utilization for 30,000+ equities across North America, EMEA, and APAC. If a hedge fund in London is aggressively shorting a Japanese semiconductor stock, you will see the borrow cost spike in our feed in real-time.
