Polymarket filed applications with the National Futures Association earlier this month to bring margin trading to its US-regulated prediction-market operations, matching a pathway Kalshi opened in March. The NFA is the US self-regulatory body that oversees derivatives intermediaries; an approved application would let Polymarket let users post collateral and trade event contracts with leverage, rather than only buying and selling contracts outright.
Why it matters
Kalshi's March approval was the first regulated US prediction-market venue to get margin treatment, and Polymarket's filing confirms the CFTC-filed contracts are moving toward a true derivatives posture, not just a spot binary-event book. Two venues chasing the same structure in the same quarter is a strong signal that regulated US event-derivatives is becoming a category rather than a curiosity, and the venue that wins a second approval will set the operational template the rest of the NFA-regulated cohort copies.
Market impact
Prediction-market platforms have run on cash-account rails since launch, capping leverage at the size of the underlying position. Margin treatment widens the addressable audience to professional market makers and prop-style books, expands revenue per active user, and lets the venue hedge exposure internally. The competitive read: Polymarket still trades more volume globally, but Kalshi owns the US regulatory timestamp, so Polymarket is paying in applications for the right to neutralize that edge.
Frequently asked questions
-
What did Polymarket actually file for?
Polymarket filed applications with the National Futures Association to offer margin trading in its US-regulated prediction-market operations, letting users post collateral and trade event contracts with leverage rather than buying and selling contracts outright.
-
Which regulator is reviewing the application?
The National Futures Association, the US self-regulatory organization that oversees derivatives intermediaries, is reviewing Polymarket's filing. The NFA sits between CFTC-regulated venues and their underlying broker infrastructure.
-
How is this different from Kalshi's approval?
It mirrors Kalshi's path rather than opening a new one. Kalshi received NFA approval in March to provide margin trading, and Polymarket's filing confirms the structure Kalshi pioneered is becoming a category rather than a one-off exception.
-
Why does margin trading matter for a prediction market?
Prediction markets have run on cash-account rails, which caps leverage at the size of each underlying contract. Margin treatment widens the addressable audience to professional market makers and prop-style books, lets the venue hedge exposure internally, and expands revenue per active user.
-
What is the competitive read between Polymarket and Kalshi?
Polymarket still trades more volume globally, but Kalshi owns the US regulatory timestamp. Polymarket's filing is the operational move required to neutralize that US edge before the gap widens further.
