Clarity Act signed into law in 2026?

Platform comparison

Market context

The Digital Asset Market Clarity Act of 2025 (H.R.3633) passed the House on 17 July 2025 with bipartisan backing but remains stalled in the Senate Banking Committee, where a competing discussion draft—the Responsible Financial Innovation Act—has emerged [3][4]. The 39% implied probability on Polymarket reflects this legislative friction; unlike Kalshi’s decimal odds or Betfair’s spread betting, Polymarket’s binary probability format and lower fee structure (often 1–2%) contrast with Kalshi’s KYC-heavy, regulated US model and Smarkets’ higher commission tiers on non-binary outcomes.

Historically, similar crypto market-structure bills like FIT21 (H.R. 4763) passed the House in 2024 but failed Senate approval, underscoring the difficulty of aligning SEC and CFTC jurisdictions [1]. California’s 2023 DFAL law, which became effective in 2025, shows state-level momentum but does not guarantee federal passage [1]. The current probability aligns with past patterns where House-passed crypto bills face Senate gridlock unless a unified framework replaces competing drafts.

Traders should monitor Senate Banking Committee hearings, any joint SEC-CFTC rulemaking announcements, and whether the RFIA draft is superseded by CLARITY language [2][4]. A key catalyst is the White House’s stance on digital commodity jurisdiction, as executive support often accelerates stalled bills. Recent reporting notes the Senate’s preference for SEC-centric regulation, which could delay or alter CLARITY’s CFTC-exclusive spot-market provisions [4]. On Polymarket, this uncertainty is priced as a 61% NO outcome, whereas Kalshi users would see this as 0.61 decimal odds with stricter identity verification.
