Options Data Pricing Compared: FlashAlpha, ThetaData, Polygon, SpotGamma, SqueezeMetrics

Full disclosure: I built FlashAlpha. I am going to be honest about where every other provider is the better buy, because a rigged pricing table gets one click and zero customers.

Data integrity note: all competitor prices below are what I could verify on each provider's own site as of June 2026. Pricing for data products changes constantly. Treat every external figure as "as of June 2026, verify on the provider's site" and click through before you buy. Where a provider does not publish a number, I describe the tier qualitatively rather than invent one.

First: These Are Three Different Products

Before any price matters, understand that the five providers are not interchangeable. They fall into three categories, and comparing prices across categories is how people overpay or underbuy:

• Raw data feeds (ThetaData, Polygon.io). You get the chain, quotes, trades, per-contract Greeks and IV. You build the analytics. Cheapest sticker price, highest engineering cost.
• Dealer-positioning dashboards (SpotGamma, SqueezeMetrics). You get GEX, dark-pool flow, and dealer-positioning charts in a browser. You consume a view, you do not build a system. Mid-to-high sticker price, near-zero engineering cost, limited programmatic access.
• Computed analytics API (FlashAlpha). You get pre-computed exposure analytics (GEX/DEX/VEX/CHEX, max pain, vol surfaces, VRP, regime) over a REST API plus dashboards plus an MCP server. Mid sticker price, near-zero engineering cost, full programmatic access.

The honest framing: ThetaData and Polygon sell you ingredients. SpotGamma and SqueezeMetrics sell you a finished meal you eat in their restaurant. FlashAlpha sells you the finished dish in a container you can take anywhere and reheat in your own code.

The Pricing Table You Came For

Tier-by-Tier: What You Get for the Money

ThetaData (raw data, the value play)

As of June 2026, ThetaData publishes three retail options tiers: Value ($40/mo) with real-time access, 4 years of history, and 1-minute snapshots; Standard ($80/mo) adding tick-level trade/quote data and 8 years of history; and Pro ($160/mo) with full tick streaming for every option trade and 12 years of history. A free tier gives 30 days of end-of-day data. Verify on thetadata.net/pricing.

Value per dollar: excellent, if you want raw inputs. Tick-level options data at $80/mo is genuinely cheap. But you get per-contract Greeks, not aggregated GEX. There is no gamma flip, no dealer regime, no max pain, no vol surface. You build all of that yourself. Full FlashAlpha vs ThetaData breakdown.

Polygon.io / Massive (raw infrastructure)

Polygon rebranded to Massive in late 2025; the options product and pricing carried over. As of June 2026 the options tiers are Starter ($29/mo) with 15-minute-delayed data and 2 years of history, Developer ($79/mo) with second aggregates and 4 years of history, and Advanced ($199/mo) with tick-level history, real-time Greeks and IV, and unlimited WebSocket subscriptions. Verify on massive.com/pricing.

Value per dollar: the most complete raw feed in the retail-accessible range, but note the entry tier is delayed data. Real-time options effectively starts at the $199 Advanced tier. Like ThetaData, you bring the analytics layer. FlashAlpha vs Polygon, raw vs computed.

SpotGamma (dealer-positioning dashboard)

SpotGamma is a browser-first product for dealer positioning. As of June 2026 its published tiers are Standard ($89/mo, or $67/mo billed annually), Essential ($99/mo), Pro ($129/mo), Alpha ($299/mo, or $224/mo annual), and Institutional from $1,999/mo. The page was mid-refresh when checked, so tier names may shift, verify on spotgamma.com.

Value per dollar: strong for a discretionary trader who wants a daily founder's note, HIRO intraday flow, and key levels without writing code. Weak if you want to build a system: SpotGamma is not API-first, so you are paying for a view, not a feed. SpotGamma vs FlashAlpha for GEX.

SqueezeMetrics (dealer-positioning dashboard, the DIX original)

SqueezeMetrics is the team that popularised the DIX (Dark Index) and a widely-cited GEX methodology. As of June 2026 they publish a single Data plan at $720/mo ($8,640/year via ACH or wire), covering 4,500+ securities, history back to 2011, spreadsheet downloads, API access, and their research dashboard. Free historical CSVs are available, but there is no free live tier. Verify on squeezemetrics.com/monitor/plans.

Value per dollar: niche and premium. If your strategy is built specifically around DIX dark-pool flow and the SqueezeMetrics GEX definition, there is no substitute, that signal is theirs. But at $720/mo flat with no entry tier, it is the most expensive on-ramp here, and the API surface is built around their dataset rather than a broad analytics suite.

FlashAlpha (computed analytics API)

FlashAlpha publishes a permanent Free tier (5 requests/day, no credit card, no expiry), then Basic ($79/mo), Growth ($299/mo, the popular tier, $239/mo billed yearly), and Alpha ($1,499/mo, $1,199/mo yearly) for quants. What each tier unlocks:

Value per dollar: you pay for the math being done and exposed over an API. A single call returns per-strike GEX, gamma flip, walls, and regime, what would be 2,000+ lines of code on a ThetaData or Polygon feed. The free tier lets you validate before spending. The trade-off: you consume FlashAlpha's methodology, and per-contract granularity is not the focus.

For redistribution or embedding analytics in a product you sell, FlashAlpha has separate commercial tiers (sales-led): Builder $249/mo, Startup Commercial $599/mo, Embedded $2,500/mo, Research $2,500/mo, and Enterprise (contact sales). Standard tiers are licensed for personal or single-team internal use. See commercial interest.

Value Per Dollar, By Job

The cheapest provider depends entirely on what you are doing. Work down to your job:

The cheapest GEX data overall? If you mean "cheapest way to get a gamma-exposure number into a system," it is FlashAlpha's free tier (single-expiry GEX, $0). If you mean "cheapest raw chain to compute your own GEX," it is Polygon Starter at $29/mo (but delayed) or ThetaData Value at $40/mo (real-time), plus your engineering time. If you mean "cheapest finished GEX dashboard to look at," it is SpotGamma annual at $67/mo. Three different "cheapest" answers, because three different products.

The Honest Recommendations

• ThetaData if you are a price-sensitive quant who will happily build the analytics layer on raw tick data. Best raw-data value, full stop.
• Polygon / Massive if you need the broadest raw feed and WebSocket streaming and you have engineers to build on it. Budget for the $199 real-time tier, not the $29 delayed one.
• SpotGamma if you are a discretionary trader who wants to read dealer positioning in a browser with daily commentary and never touch an API. Cheapest finished dashboard.
• SqueezeMetrics if your strategy is built on DIX and their specific GEX definition. The signal is unique; the price is premium and there is no entry tier.
• FlashAlpha if you want computed exposure analytics (GEX/DEX/VEX/CHEX, max pain, surfaces, VRP, regime) over an API, with a free tier to validate, SDKs in five languages, an MCP server for AI assistants, and a Historical API for minute-resolution backtests. Best value when your edge is the strategy, not the data engineering.

And the combination most quants actually run: a raw feed (ThetaData or Polygon) for per-contract granularity where they need it, plus FlashAlpha for the computed market-structure signals they do not want to rebuild. The single-vendor stack rarely wins; the two-vendor stack does.
