The short answer
Intrinio and Polygon.io both sell plan tiers now. Intrinio retired its per-feed price list for three plans: Individual $150/month (one seat, no redistribution or external display), Startup $333/month to start, and Enterprise from $1,250/month. Polygon.io (now Massive) tops out at $199/month for Stocks Advanced with unlimited real-time US-equity calls (both verified 2026-07-25). Intrinio's entry tier is cheaper and bundles options and fundamentals, but on its own FMV feed and a one-seat licence.
Intrinio and Polygon.io both sell subscription plans now, and that is the news: Intrinio retired the per-product price list this article used to quote and replaced it with three tiers, Individual $150/month, Startup $333/month to start, and Enterprise from $1,250/month, while Polygon.io (now Massive) still tops out at $199/month for Stocks Advanced with unlimited real-time US-equity calls, both verified 2026-07-25 against each vendor's pricing page. On sticker price Intrinio's Individual tier now undercuts Polygon's real-time tier, but it is a one-seat licence with no redistribution or external display, and its real-time equity and options data is Intrinio's own fair-market-value feed rather than exchange-sourced. The choice is about licence and data provenance, not price. Model either tier against your universe in the Data Vendor TCO.
TL;DR
| Dimension | Intrinio | Polygon.io (Massive) |
|---|---|---|
| Pricing model | three plan tiers | flat retail subscription |
| Entry to real-time equities | Individual $150/mo (FMV feed) | Stocks Advanced $199/mo |
| Licence at that price | 1 seat, no redistribution or external display | individual use only |
| Business-wide licence + display rights | Startup $333/mo to start | not offered on these tiers |
| Exchange-sourced real-time options | Enterprise tier, price not published | not sold as a retail tier |
| Cheapest path | free trial, then Individual $150/mo | Basic $0/mo, then Starter $29/mo |
| Best fit | one seat wanting equities + options + fundamentals in one plan | unlimited-call real-time US equities |
All figures verified 2026-07-25 against each vendor's official pricing page. Both now publish plan tiers; neither publishes a per-product price list.
What changed at Intrinio
Intrinio used to sell named feeds with their own monthly prices, and this comparison used to quote them. That is gone. The pricing page now shows three plans, and the feed catalogue below them carries no dollar figures at all: each feed is either marked Included on All plans or labelled Enterprise, whose price is quoted by sales (verified 2026-07-25).
- Intrinio plans (verified 2026-07-25): Individual $150/month, billed monthly, one seat, no redistribution or external display. Startup $333/month to start, billed quarterly, on a phased ladder that runs six months at $333, six months at $666, then $999 thereafter, and is the first tier carrying a business-wide licence with display and commercial use. Enterprise from $1,250/month on custom terms, adding custom datasets, white-glove onboarding, a dedicated account manager and an SLA.
- Polygon / Massive Stocks tiers (verified 2026-07-25): Basic $0/month (end-of-day, 5 calls/minute), Starter $29/month (15-minute delayed, unlimited calls), Developer $79/month (15-minute delayed, unlimited calls, 10 years of history), Advanced $199/month (real-time, unlimited calls, 20+ years of history). Every tier is marked individual use only.
If you are working from an older comparison that quotes Intrinio at $1,250 or $2,500 per feed, it is describing a price list Intrinio no longer publishes.
Where Polygon.io wins
Unlimited calls on exchange-grade real-time equities. Polygon's $199/month Advanced tier turns on full real-time US-equity data with unlimited API calls, no sales call, instant key (verified 2026-07-25). A research loop hammering the REST API all day pays the same $199 whether it makes a thousand calls or a million, and the price does not step up on a schedule.
A genuinely free rung. Massive still publishes a $0/month Basic tier with end-of-day data at five calls a minute. Intrinio offers free trials but no permanent free plan, so for a prototype that only needs daily bars, Polygon costs nothing to start.
Where Intrinio wins
One plan covering equities, options and fundamentals. The Individual tier at $150/month bundles EquitiesEdge and OptionsEdge real-time FMV pricing, US fundamentals, EOD and historical data for both stocks and options, 15-minute delayed CBOE data and tick-level market data, with no exchange fees or exchange paperwork (verified 2026-07-25). Assembling that coverage on Polygon means adding its options product to the $199 stocks tier.
Synthetic options without OPRA paperwork. OptionsEdge is Intrinio-sourced synthetic options pricing with implied volatility and the Greeks, and it deliberately avoids OPRA licensing complexity. It is included on all plans rather than sold separately. The exchange-sourced alternative, the low-latency Real-Time Options streaming feed sourced from OPRA, sits in the Enterprise tier with no published price.
A licence you can put a business behind. Intrinio's Startup tier is the only thing in this comparison that grants a business-wide licence with display and commercial use. Every Massive Stocks tier, including $199 Advanced, is marked individual use only, so a product that shows quotes to users is out of scope on both Intrinio Individual and every Polygon retail tier.
How to choose
- Prototyping on daily bars: Polygon Basic ($0/mo) or Starter ($29/mo, 15-min delayed).
- One developer, unlimited real-time US equities: Polygon Advanced ($199/mo).
- One developer wanting equities, options and fundamentals in a single plan: Intrinio Individual ($150/mo), accepting FMV rather than exchange-sourced pricing.
- A product that displays data to users, or more than one seat: Intrinio Startup ($333/mo to start, rising to $666 then $999) is the entry point; budget for the phased ladder, not the headline.
- Exchange-sourced streaming options with Greeks, index constituents, analyst estimates: Intrinio Enterprise, quoted by sales.
The old framing here was "retail subscription or institutional feed," and it no longer holds: both vendors sell plans. The live question is what your licence has to permit and whose real-time data you are willing to run on.

Verified figures
Polygon / Massive's flat Stocks tiers (Basic $0, Starter $29, Developer $79, Advanced $199, with Advanced carrying real-time data and unlimited calls) and Intrinio's three plans (Individual $150/mo, Startup $333/mo to start on a 6-month $333 then 6-month $666 then $999 ladder, Enterprise from $1,250/mo) were verified on 2026-07-25 against each vendor's pricing page. Intrinio publishes no per-feed prices and no per-product rate limits; feeds are marked either included on all plans or Enterprise. Where a figure was not shown, it is omitted rather than estimated.

Frequently asked questions
- Is Intrinio or Polygon.io cheaper in 2026?
- Intrinio, at the entry tier. Its Individual plan is $150/month and bundles real-time FMV equity and options pricing plus US fundamentals, against Polygon's $199/month Stocks Advanced for unlimited real-time US-equity calls. The catch is the licence and the source: Intrinio Individual is one seat with no redistribution or external display, and its real-time pricing is Intrinio's own fair-market-value feed rather than exchange-sourced (verified 2026-07-25).
- Does Intrinio still price its feeds individually?
- No. Intrinio's pricing page now lists three plans, Individual $150/month, Startup $333/month to start and Enterprise from $1,250/month, and its feed catalogue carries no dollar figures: each feed is marked either included on all plans or Enterprise, with the Enterprise price quoted by sales. Older comparisons quoting $1,250 or $2,500 per named feed describe a price list Intrinio no longer publishes (verified 2026-07-25).
- Which is better for a solo developer?
- It depends on which data you need. Polygon.io is self-serve with an instant key and a free Basic tier: $0/month end-of-day, $29/month Starter and $79/month Developer at 15-minute delay, $199/month Advanced for real-time. Intrinio Individual at $150/month is cheaper than Advanced and adds options and fundamentals in the same plan, but it is one seat, non-display, and real-time equities come from its FMV feed rather than the exchanges (verified 2026-07-25).
- Does Polygon.io offer streaming real-time options data?
- Polygon does not sell a flagship retail real-time-options streaming tier. Intrinio includes its synthetic OptionsEdge feed (implied volatility and Greeks, no OPRA licensing complexity) on all plans, and sells the OPRA-sourced low-latency Real-Time Options streaming feed in its Enterprise tier, where no price is published (verified 2026-07-25).
