A fast‑moving week reshaped both the political narrative and the prediction markets, with Congress locked in high‑stakes battles, geopolitical tensions rising, and traders aggressively repositioning ahead of spring.


I. Washington’s Biggest Stories This Week

1. Senate Gridlock Over the SAVE America Act

The Senate spent another intense week debating the Safeguard American Voter Eligibility (SAVE America) Act, which would require proof of citizenship to register and ID to vote. President Trump has framed the bill as essential to election integrity, while Democrats remain unified in opposition.
Market impact: Traders see little chance of passage under current Senate math, but the debate is driving volume in election‑administration markets.

2. DHS Funding Standoff Drags On

The Department of Homeland Security remains partially unfunded as negotiations stall between the White House, Senate Democrats, and House Republicans. Trump ordered TSA officers to be paid regardless of congressional action, attempting to blunt travel disruptions.
Market impact: Shutdown‑duration markets surged, with long‑tail outcomes gaining liquidity.

3. House Ethics Trial Draws National Attention

Rep. Sheila Cherfilus‑McCormick (D‑FL) was found guilty of 25 ethics violations related to alleged misuse of federal relief funds. The rare public trial has intensified scrutiny on congressional oversight.
Market impact: Minimal direct effect, but corruption‑related markets saw a bump in activity.

4. Iran Conflict and Cyber Escalation

Iran‑linked hackers released emails they claim were taken from FBI Director Kash Patel, adding to a week of heightened tensions as the Iran conflict enters its fourth week.
Market impact: Middle East escalation markets dominated global volume.

5. Vaccine Policy Fight Hits a Wall

Health Secretary Robert F. Kennedy Jr.’s proposed overhaul of the childhood vaccine schedule remains blocked in court. The administration faces legal and staffing challenges as the issue remains unresolved.
Market impact: Public‑health policy markets saw modest but steady trading.
