Our take · Polymarket
Will another country leave OPEC in 2026?
Market says
16%
We think
20%
Iraq is openly threatening to walk out over quotas, with a decision point in late November. We put the chance near 20% — close to the market's 16%, so we're passing.
Why we're passing
Our revised view (20%) sits just 4 points above the market (16%) — below our 5-point threshold for taking a position. The research found real risk (Iraq's November trigger), but not enough edge to bet on.
Our thinking
This one changed as we dug in. The UAE already left OPEC in May 2026 — the first Gulf major to walk out. Now Iraq is openly threatening to follow: it formally asked for a much higher production baseline in September and warned it could reconsider its membership if the late-November OPEC meeting says no. Venezuela is also reportedly weighing an exit tied to its oil deal with the US. The old pattern of a departure every few years, plus a dated trigger in November, makes this much more live than history alone suggests. We land near 20% — but that's close enough to the market's 16% that there's no edge worth taking.
Key facts
UAE left OPEC effective May 1, 2026
The UAE announced April 28 it was withdrawing from OPEC and OPEC+, ending nearly 60 years of membership — the first departure of a major Gulf producer, driven by quota frustration (3.4 mbpd quota vs ~5 mbpd capacity targeted for 2027).

Iraq formally demanded a higher baseline in September
Iraq asked OPEC for a 6 million barrel/day production baseline (vs its current ~4.4 mbpd ceiling) and warned it could reconsider its membership if denied. Its oil ministry spokesman said a decision on staying or leaving 'will have to be made' without a raised quota.

Decision point: late-November OPEC ministerial meeting
OPEC+ commissioned an external review of each member's production capacity to set 2027 quotas. Completion slipped to mid-November, with ministers ratifying in late November — that's when Iraq's demand gets answered.

The departure pattern is accelerating
Qatar left in 2019, Ecuador in 2020, Angola in 2024, UAE in 2026 — four departures in seven years, almost always over quota clashes. The 'once a decade' base rate is stale.

What would change our mind
- Any OPEC member announces departure or suspension
- Credible reporting of a formal withdrawal process begins
How confident are we
Moderately confident in the analysis, but the edge over the market is too small to act on. Iraq has threatened before and stayed.

What if Hormuz stays choked through winter? →
The strait has effectively collapsed since the Feb 28, 2026 strikes on Iran: EIA put 2Q26 transits at 4.9 mb/d against a 21.6 mb/d 4Q25 baseline, and Kpler's strongest August week showed 4.26 mb/d of crude leaving. Transits run at 3–7 vessels a day, and the main Saudi bypass pipeline was shut by drone attack in September. This guide models how long the choke persists through winter, whether the remaining ~4–5 mb/d of crude flows erode further, and how much stockpile cover buffers the gap — while flagging the widely disputed flow figures.
What if energy infrastructure gets hit next? →
The US-Iran war is underway since February 28, 2026; Hormuz tanker traffic has slowed to a trickle, and a mid-September 2026 drone attack shut Saudi Arabia's East-West Pipeline, which had been moving 4-5 million barrels a day. This scenario models NEW physical damage to Gulf energy infrastructure beyond what has already happened — to processing plants, export terminals, or pipelines on either side of the Gulf. Tension, threats, or shipping rerouting alone do not count: the dial only counts operator- or EIA-confirmed physical capacity destroyed.
