Nasdaq Launches Nasdaq-100 Binary Options Reference Index

Nasdaq said it would begin disseminating the Nasdaq-100 Binary Options Reference Index on Thursday, 2 July 2026 through the Nasdaq Global Index Data Service.

The new index uses the instrument ID NDXB, is denominated in U.S. dollars and is distributed with a one-second frequency. Nasdaq said data recipients will receive real-time index information through GIDS, with related directory messages supported for index reference data and daily activity summaries. Nasdaq also said component and weighting data will be available through Nasdaq Global Index Watch and FlexFile delivery.

The notice is a market-data and product-infrastructure update rather than a broker launch. Still, new reference indexes can become important quickly if exchanges, brokers or vendors use them to support options pricing, binary-style payoff displays or risk tools tied to Nasdaq-100 exposure.

Why it matters

Traders who use Nasdaq-100 derivatives already track multiple reference values across index, ETF and futures products. A dedicated binary options reference index adds another data point that platforms may surface in options chains, risk screens or structured-product tools.

Data-feed timing also matters. A one-second dissemination interval is fast enough for most screen-based trading and broker display use, but latency-sensitive strategies will still need to review the full feed specification.

What to watch next

Watch whether brokers, data vendors or options venues adopt NDXB in front-end displays or contract specifications. Traders should also check whether any binary-linked products disclose settlement, calculation and dissemination details separately from the Nasdaq alert.
