The Senate voted down Bernie Sanders’ resolutions to block arms sales to Israel, and Polymarket’s ceasefire breach by April 21 market now sits at 11.5% YES, down from 62% a week ago.
The Senate’s rejection has traders reassessing the likelihood of a ceasefire breach. With the US continuing to supply Israel’s military, escalation remains possible, but the ceasefire breach by April 21 contract’s collapse from 62% to 11.5% in seven days shows traders are skeptical about an immediate breakdown.
In the permanent peace deal market, odds for an agreement by April 22 are at 15.5% YES, up slightly from 20% yesterday, though the arms sale approval weighs against near-term optimism. Longer-term contracts tell a different story: May 31 is at 58.5% YES and June 30 at 72% YES.
The ceasefire market trades $2,291 in USDC daily, with a 2-point drop at 4:25 PM as the largest recent move. It takes $2,889 to shift odds by 5 points, which points to moderate trader commitment. The peace deal market is more liquid: $350,399 in daily USDC volume and $38,592 needed for a 5-point shift.
The Senate vote confirms continued US support for Israeli arms transfers, which complicates peace negotiations. The absence of any ceasefire breach announcement suggests traders read this as managed escalation, not a full breakdown. At 12¢, a YES share on ceasefire breach pays 8.3x, which attracts traders betting on conflict within five days.
Watch for Trump’s statements on Truth Social or through White House press briefings. Any mention of ceasefire violations or escalation will move these markets.
