Polymarket's Aug. 10 board: July jobs reset Fed odds, but Hormuz still fails the physical test (2026)

The most liquid repricing on Polymarket this week was a retreat from a September Fed hike, not a clean turn toward rate cuts. The September hike contract fell from an inferred 56.5% to 37.5%, while the no-change contract rose from 42.5% to 60.5%. The shift followed a July payroll report that showed a 23,000 job loss and a 103,000 downward revision to May and June gains. 1 2

Hormuz moved in the opposite direction. The probability of traffic returning to normal by Aug. 31 fell from 12.5% to 3.85%, even as Iran-Oman talks continued. Reuters counted 33 transits from Monday through Thursday, down from 50 in the comparable week. The board's message is blunt: rates are waiting for data; shipping is waiting for proof. 3

Window and cutoff: Aug. 3, 2026 at 09:00 through Aug. 10, 2026 at 09:00 ET. The Polymarket Gamma snapshot was updated at about 09:12 ET on Aug. 10. One-week changes are the platform's rolling fields; starting probabilities below are inferred as current probability - displayed change. Probabilities are Yes prices before fees and spread. Open interest is the parent-event figure where the child market did not expose its own value.

The board at a glance

The table keeps the fields that matter for a trade screen: current probability, change, volume, open interest, and execution quality. The numbers come from Polymarket's current market records, not from a reconstructed chart. 4

Market	Yes now	Inferred start → now	1-week volume	Parent OI	Liquidity / spread
Hormuz traffic normal by Aug. 31	3.85%	12.50% → 3.85% (−8.65 pp) 5	$5.37M	$5.69M	$1.33M / 0.1 pp
Fed cut by 25 bps in September	1.45%	1.25% → 1.45% (+0.20 pp) 6	$2.98M	$6.13M	$867K / 0.1 pp
Fed hike by 25 bps in September	37.5%	56.5% → 37.5% (−19.0 pp) 7	$2.10M	$6.13M	$390K / 1.0 pp
Fed holds in September	60.5%	42.5% → 60.5% (+18.0 pp) 8	$2.06M	$6.13M	$382K / 1.0 pp
Hamas agrees to disarm by Dec. 31	42.0%	55.0% → 42.0% (−13.0 pp) 9	$185K	$352K*	$67K / 2.0 pp

*The Gaza market is marked disputed under UMA. Its open interest is the linked event figure; the child record did not expose an authenticated Yes-versus-No flow measure. 9

The raw leaderboard also contained expired-looking political contracts and sports markets with large nominal turnover. They are not comparable to a liquid, still-open macro position. That distinction matters this week: high volume without a valid deadline or a usable book is noise, not a signal.

Rates: the jobs report erased the hawkish tail

The July employment report arrived on Aug. 7 at 8:30 a.m. ET. Payrolls fell by 23,000, against a Reuters consensus for an 80,000 increase. May and June were revised down by a combined 103,000. The unemployment rate fell to 4.1% from 4.2%, but that drop came as 264,000 people left the labor force; participation fell to 61.4%, a near five-and-a-half-year low. 1 2

That combination explains why the market moved toward a hold without pricing a cut. The labor signal weakened, but the participation-rate detail is not the same thing as a healthy disinflationary soft landing. Reuters reported that September hike pricing fell to 44% from 57% in its LSEG snapshot after the release. Polymarket's later 37.5% price is directionally consistent with that reset, but the two markets use different venues and timestamps. 2

The Yes case for a September hike still has a real anchor. On July 29, the FOMC held the target range at 3.50%–3.75% by a 9–3 vote. Beth Hammack, Neel Kashkari, and Lorie Logan preferred a 25-basis-point hike. The statement also said inflation remained elevated and cited energy supply shocks. 10

The No case gained the better immediate catalyst. The Fed can wait when employment is losing momentum, and the July report did not force an emergency response. The market is therefore separating a possible hike later in the year from a hike at the very next meeting. The next scheduled test is the Sept. 15–16 FOMC meeting, which includes a Summary of Economic Projections. 11

Trade idea — conditional inference, not a recommendation: Treat 50% on the September hike as the line that changes the watchlist, not as a magic entry price. A sustained move back above it after fresh inflation and labor data would put long-duration growth and long-maturity Treasuries back on the vulnerable side; a move below it with softer inflation would favor duration relief. For a retail-sized expression, a defined-risk ETF option spread is easier to cap than a naked short. The trade thesis is invalid if the data and the market price disagree for more than one release.

Hormuz: negotiations improved the headline, not the shipping tape

The Aug. 31 contract resolves Yes only if IMF PortWatch records a seven-day moving average of at least 60 Strait-of-Hormuz transit calls on any qualifying date before the deadline. At 3.85%, the market is not forecasting a small delay; it is saying that the resolution condition remains remote. 5

The physical evidence moved the wrong way. Reuters counted 33 vessels through Thursday, versus 50 in the week-ago period. Only six crude tankers had exited, while 21 vessels had entered, mostly through the Iranian route. Normal traffic before the closure was roughly 130–140 ships in a comparable period. 3

The Yes case is a negotiated reopening mechanism. On Aug. 4, an Iranian source told Reuters that the proposal under discussion would give Iran control over inbound shipping and visibility over outbound traffic, with Oman granting exit clearance. That is a concrete mechanism, not just a diplomatic slogan. 12

The No case has more pieces that must line up. On Aug. 9, Reuters reported that Tehran tied reopening to compensation, an end to sanctions and military threats, removal of a U.S. naval blockade, and other demands. Iran and the United States were not in direct talks, while the Iran-Oman channel was still working through technical language. A route proposal can exist without producing normal traffic. 13

Trade idea — conditional inference, not a recommendation: Do not read 3.85% as a direct oil-price target. Use two confirmations: a sustained improvement in PortWatch's seven-day average and independently observed vessel traffic. If both improve, the emergency energy premium becomes a candidate for a partial hedge reduction. If traffic stays thin or attacks broaden, a small, defined-risk energy or oil-volatility position is a cleaner expression than a naked bet on invasion. A fresh statement from a negotiator is not the invalidation; verified passage is.

Gaza: a large move with a disputed resolution path

The Hamas-disarmament contract fell from an inferred 55% to 42% and traded $185,000 over the week. The 2-percentage-point spread is wide beside the Fed and Hormuz records, and UMA marks the market disputed. That is enough to keep the price in the signal column rather than the position column. 9

The Yes case has an announced framework and a possible implementation channel. Germany's foreign ministry said on Aug. 10 that the latest U.S. plan was an opportunity to make progress toward Hamas disarmament, while also warning that a complex undertaking leaves many unanswered questions. 14

The No case is the sequencing dispute. On Aug. 9, Benjamin Netanyahu said Israel would not withdraw until Hamas had fully disarmed. Hamas has said it will hand weapons to a U.S.-backed Palestinian administration only after Israel stops operations and withdraws. Reuters described the two positions as a direct conflict over what comes first. 15 16

Trade idea — conditional inference, not a recommendation: Wait for the sequence, not another announcement. A verified halt in operations followed by withdrawal and an official disarmament step would support reducing a conflict hedge and watching travel, transport, and energy-sensitive equities. If the order of operations remains contested, the 42% price is not a reason to chase either side. The UMA dispute is a position-sizing warning in its own right.

The volatility screen is louder than the trade signal

A separate scan sorted by one-week probability change found more dramatic numbers than the main board. The largest macro-relevant examples were low-liquidity threshold contracts: a Palantir $120 downside market at 4.35%, down 77.15 percentage points from an inferred 81.5%; a gold $4,000 downside market at 10%, down 70.5 points from 80.5%; and a silver $54 downside market at 20.5%, down 68.5 points from 89.0%. Their weekly volumes were only $2,921, $7,808, and $4,153, with spreads of 1.7, 2.0, and 5.0 percentage points respectively. 17

Gold has the cleanest external catalyst of the three. Reuters reported spot gold at $4,336.02 on Aug. 7, up 2.3% that day and more than 7% for the week, as the weak payroll report reduced rate-hike expectations. That price action makes a contract asking whether gold will dip to $4,000 less useful as a timing tool than as a warning about how quickly thin threshold markets can collapse when the underlying moves away from the strike. 18

Trade idea — conditional inference, not a recommendation: Use the gold contract as confirmation of a macro watchlist, not as a standalone signal. If weak labor data, lower rate expectations, and a softer dollar persist, gold exposure can stay on the watchlist; if energy inflation revives the Fed-hike tail, the same position needs a tighter risk limit. The low liquidity and wide spread make the prediction contract itself a poor substitute for a more liquid, defined-risk gold instrument.

What the board says to do before next Monday

Rates first: Check whether the September hike returns above 50% after the next inflation and labor releases. The current board favors a hold, but the July 29 dissenters keep the right tail alive.
Require physical evidence in Hormuz: Compare PortWatch's seven-day average with vessel counts. Until both improve, a diplomatic headline is not a reopening trade.
Treat Gaza as a sequencing event: Look for an official disarmament announcement, a real withdrawal step, and a halt in operations in the order required by the market's resolution language.
Discount raw volatility: A 70–77-point move on a few thousand dollars of weekly volume is a liquidity observation, not a macro forecast.

No qualifying crypto market appeared in the current top-volume and one-week-volatility scans used for this edition. That is a coverage limit, not a bullish or bearish crypto call; there is no honest Polymarket-derived crypto trade idea to add this week. The usable hierarchy is narrower: Fed repricing is the cleanest cross-asset signal, Hormuz is the largest risk with the weakest physical confirmation, and Gaza is an event-driven headline market with a disputed resolution path.

Trade ideas above are conditional inferences from prediction-market signals, not individualized investment advice. Prediction-market prices can move on thin liquidity, and contract wording, disputes, and resolution sources matter as much as the headline probability.
