## Analysis

My verification found the single most on-point precedent — the identical 2025 market — resolved NO at 1.1¢ even after a law banning DOD use of specific AI systems was signed inside its window. That precedent, plus the FY27 NDAA's cloture failure and slippage risk, plus the deregulatory administration, puts fair value near 15-22%. Politics-band calibration (5-20¢ prices resolve YES 8.4%) further argues against a contrarian YES.

## Key Evidence

Verified: the identical prior-year market 'U.S. enacts AI safety bill in 2025?' resolved NO at 1.1¢ even though the FY26 NDAA (P.L. 119-60, signed Dec 18, 2025) contained Sec. Also verified the market's full rules include four provisions (incl. FY27 NDAA failed cloture July 16 and GAAIA remains an unintroduced discussion draft.

## Risks

It's Dec 31, 2026 and a YES trade lost (or NO lost): most likely the FY27 NDAA passed in the lame duck with the Senate's human-in-the-loop autonomous-weapons provision intact and the resolver counted it — or conversely it slipped to January/got stripped in conference and the strict-resolver precedent held.

**Updated probability: 28%.** Reassessed following updated evidence.

While states like California and Connecticut have enacted specific AI safety and transparency legislation, federal efforts remain deadlocked. According to official government data and reports from Brookings, the current legislative landscape shows a trend of localized regulation rather than comprehensive national action.
