Iran struck a U.S.-linked air base in Jordan on September 9, 2026, extending a retaliation cycle that began with Iranian strikes on Kuwait, Bahrain, Jordan and Iraq on September 1-2. Iran's Revolutionary Guard fired roughly 20 ballistic missiles at Jordan's Al-Azraq air base; Jordan's military said it intercepted 18 of them. Iran also attacked ten ships, including two U.S. vessels and eight oil tankers, in and near the Strait of Hormuz that same day.

The strikes came a day after U.S. forces destroyed five more Iranian oil tankers on September 8, adding to three tankers the U.S. had already destroyed on September 5. Iranian state media framed the Jordan and shipping attacks explicitly as retaliation for the U.S. tanker strikes, continuing a months-long tit-for-tat exchange between Washington and Tehran across the Gulf region.

The prediction-market question drew no votes before resolving, leaving its listed 50% community figure a default rather than a genuine forecast. The actual outcome was yes: Iran did strike one of the four countries again before September 11, consistent with the broader pattern of escalation across the region that week.

U.S. forces destroyed five more Iranian oil tankers on September 8, 2026, in addition to three tankers already destroyed on September 5, after Iran's Revolutionary Guard fired ballistic missiles at a U.S. aircraft carrier and destroyer in the Gulf. Iran retaliated on September 9 by launching roughly 20 ballistic missiles at a U.S.-linked air base in Jordan, which Jordanian air defenses mostly intercepted, and by attacking ten ships, including two U.S. vessels and eight oil tankers, near the Strait of Hormuz.

The strikes were part of an escalating retaliation cycle: the U.S. destroyed tankers in response to Iranian missile attacks on American warships, and Iran struck Jordan and shipping in direct retaliation for the tanker strikes, continuing a monthslong exchange across the Gulf region.

The prediction-market community had put 69% odds on the U.S. hitting another Iranian vessel before September 12, and the majority view proved correct. Multiple mainstream outlets independently confirmed the same sequence of tanker strikes and retaliatory attacks, describing it as among the most significant escalations in the ongoing U.S.-Iran confrontation.

Days after President Trump announced a U.S.-Venezuela oil venture built around an estimated 65 billion barrels of reserves, the White House and news outlets named the arrangement's private partner in early September 2026. NPR reported on September 1 that the partner is North American Blue Energy Partners, a Barbados-based company owned by Venezuelan businessman Alejandro Betancourt, which received concessions to 17 Venezuelan oilfields; the Pentagon's Office of Strategic Capital holds a 35% equity stake in the venture at no cost to taxpayers. Separately, Chevron announced around September 2 that it would invest more than $7 billion over five years to more than double its Venezuela production to about 600,000 barrels a day.

The details emerged after press and congressional pressure for specifics following Trump's initial, vaguer announcement of the deal.

The prediction-market community had put only 32% odds on Washington naming the venture's private partners by September 12, and the majority view was wrong: the partner was identified, and a major existing operator, Chevron, confirmed an expanded role, both within the deadline.

No hurricane had formed in the Atlantic by September 12, 2026, setting a record for the latest start to hurricane activity in the satellite era, which began in 1966. Only five named tropical storms had formed by that point in the season, compared with a historical average of nine tropical storms and four hurricanes by mid-September. The previous record for latest first hurricane, September 11, was set in 2002 and matched in 2013.

Meteorologists attributed the unusually quiet stretch to a strengthening El Nino pattern, which produced strong upper-level wind shear across the Caribbean and the Atlantic's main storm-development region, tearing apart tropical systems before they could organize into hurricanes.

The prediction-market community had put 42% odds on the season's first hurricane forming before September 12, and the majority view proved correct: none had formed. The record-setting delay came during what is normally the peak weeks of the Atlantic hurricane season, and forecasters noted that a slow start does not rule out a burst of activity later, since El Nino's suppressing effects can weaken as the season progresses.

The S&P 500 closed at 7,656.98 on September 11, 2026, up 0.86% for the day but still below both the 7,700 threshold and its September 8 close of 7,673. The index had fallen for several sessions before the September 11 rebound, with the Dow Jones Industrial Average gaining 509 points (0.98%) and the Nasdaq rising 0.96% that day.

Markets had been under pressure from rising oil prices tied to the escalating U.S.-Iran conflict in the Strait of Hormuz, with Brent crude touching roughly $101 a barrel, its highest since May, after a tanker was struck. The September 11 rally came as oil prices eased somewhat and traders judged the previous day's August inflation report, which showed prices rising in line with expectations, as tolerable ahead of the Federal Reserve's mid-September meeting.

The prediction-market question drew no votes before resolving, leaving its listed 50% community figure a default rather than a genuine forecast. The actual outcome was no: despite the rebound, the S&P 500 closed below both 7,700 and its prior week's level, reflecting a market still weighed down by geopolitical and inflation concerns.

Adobe reported third-quarter fiscal 2026 results on September 10, 2026, with revenue of $6.76 billion, up 13% year-over-year and above the $6.69 billion Wall Street consensus. Non-GAAP earnings per share came in at $6.13, versus the $6.08 analysts expected. Adobe also said it had surpassed 1 billion monthly active users, up more than 20% year-over-year, and raised its full-year revenue guidance to a range of $26.576 billion to $26.626 billion. The company reported AI-related annualized recurring revenue growing more than 150% year-over-year.

Despite the beat-and-raise report, Adobe shares fell about 2% in regular trading and another 2% after hours, closing near $243.50. The decline reflected lingering investor concern, echoing Morgan Stanley's July 21, 2026 downgrade of Adobe to underweight, over how quickly the company can monetize its AI-driven user growth against competitive pressure on its core Creative Cloud and Document Cloud businesses.

The community had put only 39% odds on Adobe topping $6.75 billion, and the majority view was wrong: revenue cleared that bar even as the stock's negative reaction suggested investors remained more focused on AI disruption risk than on the quarter's numbers.

President Trump delivered the closing speech of the first-ever Republican midterm convention at the American Airlines Center in Dallas on September 10, 2026. He focused on driving midterm turnout, telling the crowd to "pretend I'm on the ticket," and reiterated a promised $5,000 payment to Americans if Republicans hold the House and Senate. He also covered border security, crime, inflation and food prices, energy production, tariffs, voter ID and Iran, and endorsed Ken Paxton for the Senate. Coverage of the speech's themes made no mention of a third term.

The two-night convention, held September 9-10, was the Republican National Committee's first dedicated midterm gathering, organized to rally the party's base and drive turnout for the November 2026 midterms as Trump and Vice President JD Vance sought to contrast the GOP's record with Democrats.

The prediction-market community had put 41% odds on Trump raising a third term in the speech, and the 59% majority who expected he would not was correct. The speech instead centered on economic and security themes aimed at holding Republican congressional majorities.

Oracle reported fiscal first-quarter 2027 results on September 10, 2026, posting revenue of $19.35 billion, up 30% year-over-year and above the $19.14 billion analysts expected. Cloud revenue rose 62% to $11.61 billion, and cloud infrastructure revenue more than doubled to $7.4 billion, both topping estimates.

Shares initially jumped as much as 7-8% in early trading on September 11 on the strength of those numbers and Oracle's $638 billion AI-related order backlog. But the stock reversed over the session and closed the day down roughly 1.6-2%.

Investors shifted focus from the revenue beat to Oracle's balance sheet: capital expenditures tied to its AI data-center buildout have pushed free cash flow negative and debt to roughly $125 billion, concerns that outweighed the headline growth figures by the close.

The community had put 41% odds on Oracle closing higher, and the majority view proved correct: despite beating on both revenue and cloud growth, the stock finished lower, extending a decline that has left Oracle down about 20% for the year.

The Missouri Supreme Court ruled unanimously on September 3, 2026, that the Republican-drawn 2025 congressional map could not be used for the November 2026 election, and ordered Secretary of State Denny Hoskins to certify a voter referendum petition against the map as legally sufficient. The petition, backed by the group People Not Politicians Missouri and more than 300,000 signatures, went on the ballot as Proposition A, with the court directing officials to meet the September 8 certification deadline. Missouri's prior, 2020-census-era congressional map remains in effect for November 2026 unless voters approve the new map through Proposition A.

The court held that Missouri's constitutional referendum power extends to any act of the state legislature, including redistricting, rejecting Hoskins' argument that the petition was constitutionally insufficient.

The prediction-market community was evenly split at 50%, and the actual outcome was yes: voters will get to decide the map's fate. The ruling extended a broader national pattern of state courts intervening in mid-decade congressional redistricting fights ahead of the 2026 midterms.

Ben Shelton defeated fellow American Frances Tiafoe 4-6, 6-3, 6-3, 7-5 in the 2026 US Open men's semifinal on September 11 at Arthur Ashe Stadium, reaching his first career Grand Slam final. Shelton finished with 20 aces and 47 winners to Tiafoe's 3 aces and 27 winners.

Tiafoe opened sharper and took the first set, but Shelton's serve and power took over from the second set onward. He broke late in the fourth set to close out the match, sending him to face top seed Alexander Zverev in the final.

The result capped an all-American semifinal that guaranteed a U.S. man his deepest US Open run in years, following Shelton's five-set upset of Carlos Alcaraz in the quarterfinals. Community sentiment had favored Shelton at 77% before the match, and the outcome matched that majority view.

Shelton's win kept alive the tournament's broader storyline: no American man had won the US Open since Andy Roddick in 2003, and his run to the final put that drought squarely in focus heading into the championship match.

The Justice Department asked the Supreme Court directly to stay a lower-court injunction blocking new U.S. Postal Service mail-ballot rules, rather than waiting for the 1st Circuit Court of Appeals to rule first. The emergency application, filed under the docket USPS v. California, sought to let the rules, which impose new envelope-design and voter-list requirements, take effect immediately. Circuit Justice Ketanji Brown Jackson, who handles emergency matters from the 1st Circuit, set a September 9 deadline for the states and voting-rights groups challenging the rule to respond.

As of the question's September 12 resolution date, the Supreme Court had not issued a ruling on the application; it remained pending on the court's emergency docket, consistent with the timeline the response deadline implied.

The prediction-market community had put 41% odds on the justices clearing the way for the rules by September 12, and the majority view proved correct. The Supreme Court's inaction left the mail-ballot rules blocked by the lower-court injunction, mirroring the outcome of the parallel appeal pending before the 1st Circuit.

Iran and Oman announced an interim framework in late August 2026 for a temporary shipping corridor through the Strait of Hormuz and agreed to pursue a joint mine-clearing project, with officials framing a full resolution as 30 to 60 days out. By September 11, 2026, however, neither side had announced that mine-clearing work had actually begun; the Oman-hosted talks had not produced a signed agreement.

Instead of progressing, the diplomatic track was overtaken by renewed fighting. On September 8, U.S. forces destroyed five more Iranian oil tankers, and Iran retaliated the next day with a missile strike on a U.S.-linked base in Jordan and attacks on shipping near Hormuz. Houthi forces also seized Yemen's Red Sea coastline around the same time, widening the conflict rather than narrowing it.

With the war escalating on multiple fronts, the mine-clearing framework Iran and Oman had floated in August did not advance to an announced start date.

The prediction-market community had put 64% odds on the work starting by September 11, and the majority view was wrong: no start was announced.

The Strait of Hormuz remained closed as of September 12, 2026, and Iran had not declared it open despite U.S. claims that mines blocking the waterway had been cleared. The strait has been shut since a U.S.-Israeli air campaign against Iran began in late February 2026, with Iran's Revolutionary Guard separately declaring it closed in July. Iran's deputy foreign minister publicly disputed Washington's mine-clearing claim.

Rather than easing, the broader conflict escalated on other fronts in the days before the deadline: Iran-backed Houthi forces seized full control of Yemen's Red Sea coastline, including the port of Mocha and the approaches to the Bab al-Mandeb strait, and strikes inside Saudi Arabia forced the shutdown of the kingdom's East-West oil pipeline. Shipping traffic through Hormuz stayed minimal, at roughly six vessels a day versus about 85 before the war.

With the conflict widening rather than winding down, Iran had no apparent incentive to declare the strait open. The prediction-market community had put 32% odds on Iran making that declaration, and the majority view proved correct.

The U.S. State Department raised its humanitarian pledge to Nepal to more than $3.6 million on August 30, 2026, up from an initial $500,000 commitment announced days earlier, as the death toll from catastrophic glacier-collapse flooding along the Nepal-Tibet border climbed past 675 and dozens of Americans remained unaccounted for. The expanded package included up to three months of emergency food assistance for as many as 10,000 flood-affected households.

The increase came after on-the-ground reporting detailed the scale of the disaster and the difficulty of distributing aid to remote, flood-damaged areas, prompting Washington to scale up its initial response well ahead of the September 8 deadline in the question.

The prediction-market community had put 68% odds on Washington raising its pledge, and the majority view proved correct. The episode reflected a broader pattern in the Nepal disaster response, where initial U.S. commitments were revised upward as the true scope of casualties and missing persons, including a significant number of Americans, became clearer in the days following the floods.

Meta agreed in late August 2026 to pay roughly $12-13 billion to settle a multistate lawsuit over child safety on Facebook and Instagram, with an additional $5-plus billion contingent on TikTok, YouTube or Snap adopting comparable teen-safety measures such as daily time limits, nighttime restrictions and age verification. Meta then ran an advertising and open-letter campaign urging its rivals to match the terms.

On September 11, 2026, Axios reported that TikTok had rejected Meta's ad campaign outright, refusing to run it under its policy barring what it classified as political content. Neither TikTok, YouTube nor Snap had agreed to adopt comparable safety measures by the September 11 deadline in the question.

TikTok's move effectively stalled, for now, the pressure campaign built around Meta's settlement: rather than engaging with the substance of the proposed safety standards, the company blocked the messaging vehicle Meta was using to push it.

The prediction-market community was roughly split, with 48% putting odds on a rival matching the deal, and the narrow majority leaned correctly toward no agreement being reached by the deadline.

The Bureau of Labor Statistics reported on September 11, 2026, that the consumer price index rose 3.4% year-over-year in August, matching July's rate rather than accelerating to 3.5% or higher. Core CPI, which excludes food and energy, rose 0.3% for the month, pushing the annual core rate down slightly to 2.4% from 2.5% in July. Gasoline prices climbed 3.9% in August, accounting for more than a third of the month's overall 0.4% price increase, as tensions in the Middle East kept energy costs elevated.

The report landed as markets weighed the odds of a Federal Reserve rate hike at the September 15-16 meeting. Fed Chair Kevin Warsh had signaled at the Jackson Hole conference in late August that the central bank still had work to do on inflation, and futures markets raised the probability of a hike to roughly 85% following the CPI release, up from about 59% a week earlier.

The prediction-market community had put 61% odds on CPI coming in at 3.5% or higher, and the majority view proved wrong: the headline rate held steady at 3.4%, staying below the threshold even as underlying price pressures, particularly energy costs, kept inflation elevated.

North Korea did not fire a ballistic missile during the U.S.-South Korea-Japan Freedom Edge military exercise, which ran September 7 through 11, 2026. One day after the drills concluded, on September 12, North Korea fired multiple short-range ballistic missiles from the Wonsan area on its east coast, which flew roughly 250 kilometers into the sea. South Korea's Joint Chiefs of Staff initially described the launch cautiously as an unidentified projectile before it was confirmed as ballistic missiles.

North Korean defense minister Kim Song Gi had earlier threatened retaliation over Freedom Edge and a related U.S.-Japan exercise, and the launch was widely characterized as a show-of-force response to the drills rather than a challenge issued during them.

The prediction-market community had put 38% odds on North Korea firing a missile during the exercise itself, and the majority view proved correct. The question resolved no on a timing technicality rather than a change in North Korean behavior: the missiles came a day after the drills ended, not during the September 7-11 window the question specified.

A three-judge panel of the 1st U.S. Circuit Court of Appeals denied the Trump administration's request to lift a preliminary injunction blocking the U.S. Postal Service's new mail-ballot rules on September 10, 2026. The panel found the administration had not shown that U.S. District Judge Indira Talwani erred in concluding the rule, which imposed new envelope-design, barcode and voter-list requirements, would likely disenfranchise millions of voters for minimal anti-fraud benefit. The injunction, sought by a coalition of roughly two dozen Democratic-led states and voting-rights groups, remained in effect, and the new rules did not take effect before September 12.

The court cited the risk of disrupting an election already underway, with mail ballots going out in some states, as outweighing the government's stated anti-fraud rationale for implementing the rule on short notice.

The prediction-market community had put 30% odds on the appeals court letting the rules take effect, and the majority view proved correct. The ruling kept the Postal Service operating under its prior mail-ballot procedures pending further litigation.
