Best Polygon.io Alternatives for Daily Historical Prices

By Fruit Stand Team · November 6, 2026 · Comparisons Polygon.io renamed itself Massive on October 30, 2025, and its daily prices still start in September 2003, adjusted for splits only. For dividend-adjusted or longer history, the best alternatives are Tiingo and EODHD (APIs), FirstRate Data (one-time files, delisted stocks included), Intrinio (commercial licensing) and a Snowflake Marketplace listing (SQL). Below is what changed with the rebrand, the three reasons people look elsewhere, and how each alternative compares.

Fruit Stand publishes the Historical Stock Prices listing, one of the alternatives below. Every provider’s price, history and terms were checked on its own site on November 4 to 6, 2026. The returns are from our own data.

Polygon.io is now Massive

The rename took effect on October 30, 2025. polygon.io redirects to massive.com, accounts and API keys carried over, and api.polygon.io keeps working alongside the new api.massive.com. Plans and data didn’t change, so if you’re searching for a Polygon alternative because the name disappeared, your code doesn’t need to move. Massive’s individual stock plans are Basic (free, 2 years, 5 calls a minute), Starter ($29/month, 5 years), Developer ($79, 10 years) and Advanced ($199, 20+ years, non-professionals only). Flat files start on Starter. All four are for individual use.

Why people look for a Polygon alternative

No dividend adjustment. Massive’s aggregates are split-adjusted by default, and its knowledge base says nothing is dividend-adjusted. Flat files aren’t adjusted at all, not even for splits. You rebuild adjusted prices yourself from its splits and dividends endpoints.
History starts in 2003. Its day aggregates go back to September 10, 2003, and only Advanced and business plans get all of it.
Business use isn’t self-serve. Business plans go through sales, with no base price on the business pricing page; its data feed add-ons alone run $399 to $1,999 a month.

What a split-only close misses

Over 20 years, the difference between a split-adjusted close and a dividend-adjusted one is most of the return for income stocks. From our data, November 6, 2006 to November 5, 2026 (none of the three split in that window, so the raw close equals the split-adjusted close):

Ticker	Price return (split-adjusted close)	Total return (dividend-adjusted close)
SPY	430.9%	665.2%
JNJ	298.0%	609.7%
XOM	126.7%	349.7%

A backtest on a split-adjusted close leaves out the dividends: a third of SPY’s return over the period, and more than half of Johnson & Johnson’s and ExxonMobil’s.

The alternatives at a glance

Option	Dividend-adjusted	History	Price	Commercial use	Main catch
Tiingo	Yes, plus raw prices	30+ years	Free; $30/month individual, $50 internal business	Internal use only	One ticker per request
EODHD	Yes, adjusted close	Back to 1990	From $19.99/month (personal)	On commercial plans	Bulk requests cost 100 API calls
FirstRate Data	Yes, plus unadjusted	January 2000	$499.95 one-time; updates $59.95/month	Internal use; no redistribution	Files to load yourself
Intrinio	Yes, plus adjustment factors	50+ years	$150/month (personal); $333/month to start (commercial)	On the commercial plan	The priciest here
Databento	Not stated in its closing-price example	8+ years	Pay as you go, or $199/month	Licensed in its portal	Shorter history than Massive
Alpaca	Not stated on its data page	7+ years	Free; $99/month for all US exchanges	Per its terms	Free plan is IEX-only, a small slice of volume
Fruit Stand Historical Stock Prices	Yes, plus raw OHLC	Back to each listing date, from 1962	$100/month after a 30-day trial	Per the listing terms	Snowflake only; no delisted securities

Each alternative in detail

Tiingo (cheapest dividend-adjusted API)

Tiingo’s end-of-day endpoint returns raw and adjusted open, high, low and close plus divCash and splitFactor, with 30+ years of history. It’s one ticker per request, so it suits a few hundred tickers rather than the whole market. Free covers 500 symbols a month; paid plans are $30/month for individuals and $50 for internal business use.

EODHD (whole market, dividend-adjusted)

EODHD’s bulk endpoint returns a whole exchange’s end-of-day prices for one date, like Massive’s daily market summary, and its per-ticker endpoint includes a dividend-adjusted close back to 1990. Plans start at $19.99/month for personal use, with commercial plans priced separately. Best Alpha Vantage Alternatives for Bulk Historical Prices covers its call costs and backfill time.

FirstRate Data (flat files with delisted stocks)

If you used Massive’s flat files for backtesting, FirstRate Data is the closest file-based swap that fixes both gaps. Its Stocks Complete bundle is daily and intraday history from January 2000 for 16,333 tickers, including over 7,000 delisted stocks, adjusted for splits and dividends with unadjusted data included. It’s $499.95 once, with a month of updates, then $59.95 a month. The license is for your own use: internal models and published charts are fine, redistributing the data isn’t.

Intrinio (commercial licensing)

Intrinio’s EOD Historical Stock Prices cover 50+ years with adjusted and unadjusted prices and adjustment factors, by API, CSV, S3 or Snowflake. Its $150/month Individual plan is personal use only. Commercial use and display start at $333/month on the Startup plan, rising to $999 after a year, which is a published price where Massive’s business plans aren’t.

Databento and Alpaca (recent history only)

Databento’s official consolidated daily bars cover 8+ years, and Alpaca’s historical bars 7+ years, so neither goes as far back as Massive’s 2003. Databento suits official closes for recent years; Alpaca’s free plan only includes the IEX exchange’s feed, so its bars miss most of the market’s volume unless you pay $99 a month.

Fruit Stand on the Snowflake Marketplace (research in SQL)

If you loaded Massive’s flat files into a warehouse, a Marketplace listing skips the loader and the adjustment step. Fruit Stand’s Historical Stock Prices has raw and dividend-adjusted OHLC for US stocks, ETFs and mutual funds, refreshed daily, with history back to each security’s first trading day. Of the 23,967 US stocks and ETFs in it, 4,691 have prices before September 10, 2003, where Massive’s history begins: 8.2 million rows Massive doesn’t have. It’s $100/month after a 30-day trial. The catch: it’s Snowflake only, and it doesn’t include delisted securities, so long backtests carry survivorship bias.

Which should you choose?

Staying on Massive, but need total returns: keep Massive and apply its dividends endpoint yourself, or switch the price source.
Dividend-adjusted prices for a few hundred tickers: Tiingo.
Dividend-adjusted prices for every ticker, daily: EODHD.
Backtests without survivorship bias, bought once: FirstRate Data.
A commercial app with a published price: Intrinio.
Research in SQL with nothing to load: Fruit Stand’s Historical Stock Prices listing in Snowflake.

Price return vs. total return in one query

The returns table above comes from this query against the Historical Stock Prices listing. close is the raw close and adjusted_close is adjusted for splits and dividends:

with px as (
    select code, date, close, adjusted_close
    from security_price_history_vw
    where exchange_code = 'US'
      and code in ('SPY', 'JNJ', 'XOM')
      and date >= '2006-11-06'
)
select code,
       min(date) as start_date,
       max(date) as end_date,
       round(max_by(close, date) / min_by(close, date) - 1, 3) as price_return,
       round(max_by(adjusted_close, date) / min_by(adjusted_close, date) - 1, 3) as total_return
from px
group by code
order by code;

On November 6, 2026 it returned 2.980 and 6.097 for JNJ, 4.309 and 6.652 for SPY, and 1.267 and 3.497 for XOM, through November 5. For a ticker that split in the window, compare against a split-adjusted series instead of the raw close.

F.A.Q.

Is Polygon.io shutting down?

No. It renamed itself Massive on October 30, 2025. polygon.io redirects to massive.com, and existing API keys and api.polygon.io endpoints keep working.

Does Polygon (Massive) have dividend-adjusted prices?

No. Its aggregates are split-adjusted by default, nothing is dividend-adjusted, and flat files aren’t adjusted at all. You can rebuild adjusted prices from its splits and dividends endpoints.

How far back does Polygon's stock data go?

To September 10, 2003 for day aggregates, on the Advanced and business plans. Basic gets 2 years, Starter 5 and Developer 10.

What's a cheaper alternative to Polygon for daily data?

EODHD from $19.99/month and Tiingo from $30/month, both with dividend-adjusted prices. Tiingo’s and Massive’s free plans both work for small projects.

Which alternative includes delisted stocks?

FirstRate Data’s Stocks Complete bundle includes over 7,000 delisted stocks. Fruit Stand’s Historical Stock Prices doesn’t include delisted securities.
