US announces blockade on Iran by...?
💡 What the odds say
Most likely: July 31 at about a 100% chance — almost certain.
The field is effectively closed: the market assigns near-certain probability to a US blockade announcement by July 31, driven by the rapid escalation where Houthi-declared blockades (Reuters, Jul 21) triggered US missile strikes on Iran (Marine News Magazine, Jul 24), making a formal US blockade announcement appear imminent.
What's driving it
- • Houthi announcement of a naval blockade against Saudi Arabia (Reuters, Jul 20–21) created a new front in the US-Iran war, raising pressure for a US response.
- • US retaliatory missile strikes across Iran (Marine News Magazine, Jul 24; ABC7, Jul 23) escalated the conflict, making a formal US blockade announcement a logical next step.
- • Houthis also declared blockade of the Bab el-Mandeb strait (NPR, Jul 21), directly threatening shipping lanes and prompting US action.
Why the front-runners lead
- • The sequence of events—Houthi blockade declaration then US strikes—shows a clear escalation path that almost guarantees a US blockade announcement to match the Houthi move.
- • The US military already stated it is launching strikes on Iran over shipping route clashes (ABC7, Jul 23), indicating the blockade rationale is already operational.
- • Market sees no other plausible outcome given the active conflict and Houthi actions, compressing probability to July 31.
Why it's still open
- • If the US refrains from a formal blockade announcement despite ongoing strikes, the July 31 outcome could shift to later dates, but currently no headline suggests hesitation.
- • Diplomatic intervention could de-escalate before July 31, making a blockade announcement unnecessary, but recent strikes (Jul 24) indicate the opposite.
- • The market may be overreacting to a few days of headlines; any sign of US backing down would open the field to other dates.
What to watch
- • Any official White House statement on Iran policy before July 31 would either confirm or deny an imminent blockade, moving odds dramatically.
- • A UN Security Council session on the naval blockade could provide a diplomatic off-ramp, reducing the likelihood of a US blockade announcement.
- • Continued Houthi attacks on shipping in the Bab el-Mandeb (NPR, Jul 21) would reinforce the need for a US blockade, keeping odds high.

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.

Republican Presidential Nominee 2028
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).

2028 Presidential Election Winner
The field is unusually fragmented with no candidate above 18%, and the top three sum to just 41%, reflecting a wide-open race where the biggest recent shift is the absence of a clear front-runner despite ongoing midterm elections and controversies over election integrity. The 2026 primary results (NBC News, Jul 23) are reshaping candidate viability, but no single contender has consolidated support yet.
