Will the Housing for the 21st Century Act become law this year?
🗂 Part of event: Which bills will become law in 2026? →The bill has already become law automatically without the president's signature, rendering the market's 100% Yes odds a reflection of an already-resolved event, not a prediction. The key story is the unusual enactment mechanism—a bipartisan congressional override through inaction.
📊 Base rate: Modern major housing bills have a roughly 50-60% passage rate when controlling for party control, but automatic enactment without a signature is extremely rare.
What's driving it
- • Multiple news outlets confirmed on July 10-11 that the bill became law automatically after President Trump refused to sign it (NPR, HousingWire, CNBC, U.S. News).
- • The law's official name is the 21st Century ROAD to Housing Act, which matches the resolution criteria for the market (Multi-Housing News, HousingWire).
- • No subsequent congressional action or legal challenge has been reported to reverse the automatic enactment, and the bill's effective date has passed.
The case for YES
- • Congress passed the bill, Trump declined to sign it, and under the U.S. Constitution it became law after 10 days (excluding Sundays) without his signature, as multiple July 10-11 headlines confirm (NPR, CNBC, U.S. News).
- • The market's own qualifying legislation (H.R. 6644) is the same bill that news sources report as having become law, satisfying the resolution condition.
The case for NO
- • If the legislative text or procedural details differed from the qualifying criteria in the market's description, the resolution may not match; however, no headline suggests any discrepancy.
- • A successful legal challenge or a subsequent repeal before the market's December 31 deadline could theoretically reverse enactment, but no such action is reported.
What to watch
- • July 11, 2026 (today): The law's automatic effective date has already passed; no further catalysts are expected to change the outcome.

How it resolves
Settled on-chain by UMA's optimistic oracle: once an outcome is clear, anyone can propose the result, which then enters a challenge window where it can be disputed with evidence before it finalizes.
⚖️ A proposed outcome can be disputed during a challenge window before it's final.
Resolution criteria
This market will resolve to "Yes" if legislation that would revise federal housing programs to increase housing supply and affordability by expanding federal financing and grant authority for affordable housing and streamlining federal requirements that delay housing development is passed by both chambers of the U.S. Congress and signed into law by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Qualifying legislation includes the H.R. 6644 (119th) — Housing for the 21st Century Act. Qualifying legislation may include joint resolutions and must pass both the House and the Senate, and must be signed by the President, become law without signature while Congress remains in session, or become law through veto override. Presidential pocket vetoes that expire resolve to "No". The primary resolution sources for this market will be Congress.gov’s legislation tracker (https://www.congress.gov/bill/119th-congress/house-bill/22), the Library of Congress (congress.gov), and other official information from the government of the United States; however, a consensus of credible reporting may also be used.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.

Democratic Presidential Nominee 2028
The field is virtually nonexistent: only two candidates register at 1% each, and no one has broken 5%, making this the most open Democratic nomination race in modern history. The single biggest recent shift is the DNC's decision to put South Carolina first in the 2028 primary calendar (Axios, Jul 25), which could reshape candidate strategies and favor a different type of contender.

Next Prime Minister To Replace Keir Starmer
The field is highly concentrated, with Andy Burnham absorbing nearly all of the probability after Starmer’s resignation and a key endorsement, pushing the top three candidates' combined odds to an unsustainable 110% that signals liquidity imbalances or heavy speculative positioning. The biggest recent shift is Burnham’s surge to 99% following the ‘Starmer Announces Resignation; Burnham Wins Key Endorsement’ headline (The New York Times, Jun 23).

The Republican nomination field is exceptionally fragmented, with no candidate above 5% and the top three sum to just 1% — a sign that the race is truly wide open and still in its earliest jockeying phase, despite a recent poll placing Senator JD Vance near the top of a generic primary ballot (USA Today, Jul 23).
