Defiance Act Climbs to 55% Chance of 2026 Passage, No Catalyst

---

The Defiance Act Just Jumped 11 Points With No New News to Justify It

The Senate passed S. 1837, the Defiance Act's identical Senate companion, by unanimous consent on January 13, 2026. The House version, H.R. 3562, has not received a hearing, a markup, or a publicly scheduled committee date in the ten-plus months since its referral to the House Judiciary Committee. No new co-sponsors have been added. No floor action has been taken. No committee chair has signaled intent to move the bill.

Against that procedural backdrop, the Defiance Act's implied probability of becoming law by December 31, 2026, surged from 44% to 55% over just three days across Kalshi and Polymarket. The 11-percentage-point rebound is one of the sharpest recent moves in the Which bills will become law in 2026? event, and it corresponds to exactly zero identifiable legislative catalysts.

The question is whether this price action reflects genuine information the public record hasn't caught up to, or whether thin liquidity in a niche bill-passage market allowed a small number of buyers to push the contract well beyond where fundamentals support it. The 10-point spread between platforms, with Kalshi at 60% and Polymarket at 50%, suggests the latter possibility deserves serious scrutiny.

Ten Months, Zero Hearings: Where H.R. 3562 Actually Stands in the House Judiciary Committee

Committee referral is where most bills go to die. According to the Congressional Research Service, roughly 90% of bills referred to committee in a typical Congress never receive a hearing. H.R. 3562, introduced by Representative Alexandria Ocasio-Cortez on May 21, 2025, has now spent more than ten months in the House Judiciary Committee without advancing past the referral stage.

The bill's 54 co-sponsors span both parties. Republican co-sponsors include Representative Kat Cammack of Florida. Democrats include Representatives Debbie Dingell and Ted Lieu. Bipartisan support is a necessary condition for passage but not a sufficient one: committee chairs control hearing schedules, and the House Judiciary chair has not publicly committed to taking up the Defiance Act. As previously reported, this procedural bottleneck was the primary driver when the contract fell from 56% to 46% in late March.

The legislative calendar compounds the problem. The 2026 midterm elections will compress available session days in the second half of the year. Congress typically enters a lame-duck dynamic by October, prioritizing must-pass spending legislation over standalone authorization bills. For the Defiance Act to become law by December 31, 2026, it would need a committee hearing, a markup, a Rules Committee resolution, a House floor vote, conference reconciliation if any text differs from S. 1837, and a presidential signature. That is a dense procedural chain to complete in six months, starting from a dead stop.

Reading the Defiance Act's Volatile Price History

The three-day chart tells a story of rapid repricing without an obvious trigger. The contract bottomed near 44%, matching the period low, before a sharp upward move carried it to the current 55%. The rebound's shape is steep, not gradual, which in thin markets often indicates a small number of aggressive buyers rather than broad-based conviction shifting.

The 10-point platform spread reinforces this reading. Kalshi prices the Defiance Act at 60%. Polymarket sits at 50%. When a single contract trades at meaningfully different levels on two platforms, it typically signals that arbitrage capital has not yet flowed to equalize the price, pointing to low trading activity on at least one side. Without fabricating volume numbers, we can observe that the Polymarket contract page shows modest total volume. This is not a market where institutional-scale capital is expressing a view.

Compare the Defiance Act's 55% to other bills in the same event. The Housing for the 21st Century Act leads at 95% implied probability with over $37,000 in volume on Polymarket alone. That market has the liquidity depth to absorb large orders without moving the price by double digits. The Defiance Act's contract does not appear to share that characteristic.

The Bull Case: Why Some Traders Think 55% Is Still Too Low

The optimistic thesis rests on three pillars, each carrying genuine weight.

First, unanimous consent in the Senate is rare and powerful. When 100 senators agree to pass a bill without a recorded vote, it signals that no political faction sees an upside in opposing it. Deepfake imagery legislation is a uniquely bipartisan issue: no member of Congress wants to defend nonconsensual synthetic pornography in a campaign ad. That political logic applies to the House as much as the Senate.

Second, the Defiance Act could bypass the normal committee process entirely. House leadership can bring bills directly to the floor under suspension of the rules, which requires a two-thirds supermajority but skips the committee stage. A bill with 54 bipartisan co-sponsors and a unanimous Senate vote is a plausible candidate for this path, particularly if a high-profile deepfake incident creates sudden political urgency.

Third, six months remain before the December 31 resolution date. Bills have moved from committee dormancy to presidential signature in shorter windows, especially when attached as amendments to larger must-pass vehicles like the National Defense Authorization Act. If House leadership perceives electoral value in passing deepfake protections before November, the Defiance Act could ride a larger bill to enactment.

The Bear Case: Why 55% May Be Overpriced by 20 Points or More

The strongest argument against the current price is the simplest one: the 11-point surge has no corresponding legislative catalyst. The Senate passed S. 1837 on January 13. H.R. 3562 has sat in House Judiciary for over ten months with no markup or hearing date scheduled. Nothing changed in the past 72 hours to alter that fundamental reality.

The procedural math is punishing. Six months remain, but Congress will be in session for a fraction of that time. August recess, campaign travel, and election-season distractions will consume weeks. A bill that hasn't received a single committee hearing would need to accelerate through every remaining step at an unusual pace.

The platform spread also argues for caution. Kalshi sits at 60% and Polymarket at 50%. The true implied probability, to the extent one exists, likely falls somewhere in between or below the average. The higher Kalshi price could reflect a small number of optimistic buyers in a thin book, pulling the headline number above where broader sentiment actually sits.

Finally, the base rate for bills in committee without a hearing to become law within a single Congress is extremely low. The Defiance Act has political tailwinds that most stalled bills lack, but political tailwinds and procedural motion are different things. Until the House Judiciary Committee schedules a hearing or House leadership signals intent to bring H.R. 3562 to the floor through an alternative path, 55% prices in progress that does not yet exist. The market has moved. The bill has not.
