Nasdaq Market Calendars API — earnings, dividends, IPOs, short interest & institutional holdings

One Actor for the market calendars on Nasdaq.com: the earnings calendar, dividend calendar and IPO calendar for any date range, plus per-symbol short interest history and institutional holdings (13F holders). Output is clean JSON with numbers already parsed: "$3.19" → 3.19, "($0.35)" → -0.35, "$118,229,410,000" → 118229410000, "N/A" → null, US dates → YYYY-MM-DD.

No browser, no login, no API key — it reads the same public JSON endpoints the nasdaq.com pages use, so runs take seconds.

What it does

• Earnings calendar — every company reporting on each day: time (pre-market / after-hours), consensus EPS forecast, last year's EPS, number of estimates, market cap, fiscal quarter.
• Dividend calendar — by ex-dividend date: amount, annual dividend, payment, record and announcement dates.
• IPO calendar — per month: priced, upcoming, filed and withdrawn deals with price range, shares, offer amount, exchange and dates.
• Short interest — the bi-monthly short interest history (≈ last year) for each symbol: short interest, average daily volume, days to cover.
• Institutional holdings — the top N institutional holders per symbol, sorted by position value: shares held, change, change %, value in USD, filing date.
• Loops over days (skipping weekends) or months automatically, 3 requests in parallel, with retry and exponential backoff on rate limits and server errors.
• Optional symbol filter for calendars — e.g. only get earnings dates for your watchlist.

Use cases

• Traders & investors — weekly earnings and ex-dividend watchlists, IPO pipeline tracking.
• Quant / data teams — feed an earnings-date or dividend table into a database, Google Sheets or backtests via the Apify API.
• Short squeeze screens — short interest and days-to-cover history for a list of tickers.
• Ownership research — who owns a stock, who is buying and who sold out.
• Newsletters & bots — schedule daily and post tomorrow's earnings to Slack / Discord / email.

Output

Every row has dataset and scrapedAt. Fields per dataset:

earnings

{
  "dataset": "earnings",
  "date": "2026-10-01",
  "symbol": "ACN",
  "company": "Accenture plc",
  "time": "pre-market",
  "epsForecast": 3.19,
  "lastYearEPS": 3.03,
  "lastYearReportDate": "2025-09-25",
  "numEstimates": 7,
  "marketCap": 118229410000,
  "fiscalQuarterEnding": "Aug/2026",
  "scrapedAt": "2026-10-01T01:37:31.816Z"
}

time is pre-market, after-hours or not-supplied.

dividends

{ "dataset": "dividends", "symbol": "AGNCP", "company": "AGNC Investment Corp. Depositary Shares ...", "exDate": "2026-10-01", "paymentDate": "2026-10-15", "recordDate": "2026-10-01", "announcementDate": "2026-09-09", "amount": 0.55912, "annualDividend": 2.1952 }

ipos

{ "dataset": "ipos", "status": "upcoming", "symbol": "ACCV", "company": "Accelevation Holdings Corp.", "date": "2026-09-30", "exchange": "NASDAQ Global Select", "priceRange": "20.00-24.00", "priceLow": 20, "priceHigh": 24, "shares": 30000000, "offerAmount": 828000000, "expectedDate": "2026-09-30", "pricedDate": null, "filedDate": null, "withdrawnDate": null, "dealId": "1400711-119247", "month": "2026-09" }

date is the date that matters for the status (priced → priced date, upcoming → expected date, withdrawn → withdrawal date, filed → filing date).

shortInterest

{ "dataset": "shortInterest", "symbol": "AAPL", "settlementDate": "2026-09-15", "interest": 128753092, "avgDailyVolume": 45135477, "daysToCover": 2.852592 }

institutionalHoldings

{ "dataset": "institutionalHoldings", "symbol": "AAPL", "holder": "Vanguard Group Inc", "date": "2025-12-31", "shares": 1426283914, "change": 26856752, "changePercent": 1.919, "changePercentRaw": "1.919%", "value": 469817921000, "holderUrl": "https://www.nasdaq.com/market-activity/institutional-portfolio/vanguard-group-inc-61322" }

value is in USD (Nasdaq reports it in thousands; the Actor converts). changePercentRaw keeps Nasdaq's text when there is no number ("New", "Sold Out").

Error item (never charged)

{ "dataset": "shortInterest", "symbol": "IBM", "errorType": "NOT_AVAILABLE", "error": "Short interest is not available. Short interest is only supported for Nasdaq Listed stocks" }

errorType is NOT_FOUND, NOT_AVAILABLE or FETCH_FAILED.

Pricing

Pay-per-event:

• Actor start — small fixed fee per run.
• result — per result row in the dataset.

Error items are free. Set a maximum cost per run and the Actor stops cleanly once it is reached; maxItems caps the rows too.

FAQ

Why do I get NOT_AVAILABLE for short interest on NYSE stocks? Nasdaq.com only publishes short interest for Nasdaq-listed stocks. Institutional holdings work for NYSE stocks too.

How far ahead / back can I go? Whatever nasdaq.com shows: earnings are usually announced a few weeks ahead, dividends are available for past dates too, the IPO calendar keeps history by month.

Why are some EPS forecasts null? Nasdaq has no consensus for that company (blank or N/A on the site).

Does it skip holidays? Weekends are skipped. Market holidays simply return no rows (no charge).

Do I need a proxy? Usually not. Nasdaq's API occasionally throttles or stalls cloud IPs; the Actor retries with backoff, and if you still see FETCH_FAILED items, enable Apify Proxy (residential works best).

Is the IPO "upcoming" list repeated for every month? No — Nasdaq returns the same live upcoming list for any month; the Actor de-duplicates it.
