Trump's 50% tariffs on Canadian goods took effect after trade talks between Washington and Ottawa collapsed late on Aug. 21, 2026. Canadian Prime Minister Mark Carney suspended the negotiations and said Canada would retaliate "dollar for dollar" with matching tariffs on U.S. goods. The 50% rate applied to roughly $28 billion worth of Canadian exports, replacing the pause Trump had granted earlier in August while talks continued.

Carney blamed the breakdown on what he called "uneconomic" and "unfair" U.S. demands, pointing specifically to proposed changes to auto-sector tariff treatment that he said would have damaged Canada's economy. Trump separately announced that U.S. tariffs on Canadian cars, trucks, auto parts, and steel would rise further, to 50%, starting Jan. 1, 2027, layering additional pressure onto the dispute.

The tariffs' effective date fell before the question's Aug. 28 deadline, resolving the market Yes. The community had strongly bet against this outcome, with only 17% forecasting the tariffs would take effect, reflecting widespread expectation that the two sides would reach a last-minute deal similar to earlier rounds of the trade dispute.

Nvidia stock closed at $227.98 on Aug. 27, 2026, up 8.74% for the session, after the company reported fiscal second-quarter results the previous day that beat Wall Street's expectations on nearly every metric. Quarterly revenue reached $96.22 billion, up 106% year over year, with the data center segment contributing about $89 billion of that total. The single-day gain added roughly $441.5 billion to Nvidia's market capitalization, the second-largest one-day dollar gain in U.S. stock market history, pushing its total value to about $5.49 trillion.

The rally was driven by both the outsized quarterly beat and forward guidance that implied close to 70% revenue growth for calendar 2027, nearly double what analysts had penciled in, easing investor concerns about slowing demand for Nvidia's AI chips following a volatile summer for the stock.

The close of $227.98 cleared the question's $225 threshold, resolving the market Yes. The community had leaned against this outcome, with only 39% forecasting a close above $225, underestimating the magnitude of the post-earnings surge that followed the blowout report and guidance.

Reports that Prince Harry and Meghan planned to move back to Britain first surfaced around Aug. 19, when a source told NBC News that King Charles had been informed of the couple's decision to relocate from Montecito, California, with their children Archie and Lilibet, who were said to be enrolling in British schools. Neither Harry, Meghan, nor a spokesperson for the couple issued any public statement confirming the reported plan in the days that followed, and Buckingham Palace also declined to comment.

The family did arrive in the United Kingdom on Aug. 27, after the question's Aug. 26 deadline, for what was described as an "extended" stay, but even then neither the couple nor their office issued an on-the-record confirmation of a permanent or long-term relocation; a spokesperson cited privacy and security concerns in declining to discuss their living arrangements. The reporting relied throughout on anonymous sources rather than statements attributable to Harry, Meghan, or their office.

Because no public confirmation came from the couple or their representatives before the deadline, the question resolved No. The community leaned toward Yes at 54%, overestimating the likelihood of an official statement within the window.

On Aug. 28, 2026, the U.S. Treasury's Office of Foreign Assets Control added Reza Mohammad Taeedi, an Iranian national serving as general manager of the Dubai branch of Iran's state-owned Bank Melli, to its Specially Designated Nationals list. OFAC simultaneously designated Kameng Trading Limited, a Hong Kong-based company formed in July 2024, under an Iran-related executive order, citing its role helping a sanctioned Iranian exchange house launder money and access the international financial system.

The action was part of what Treasury officials called "Operation Economic Outcast," targeting Iran's use of banks in the United Arab Emirates and trading networks in Hong Kong to move money despite sanctions. It followed President Trump's mid-August declaration of an "economic D-Day" against Tehran, under which Treasury rolled out a series of designations against Iranian oil-shipping networks, exchange houses, and the foreign banks and companies servicing them.

The Aug. 28 action landed a day before the question's Aug. 29 deadline, satisfying the resolution criterion that a non-Iranian company or bank be sanctioned over Tehran ties. The community was evenly split at 50% ahead of resolution, reflecting real uncertainty about whether a qualifying designation would land within the window.

Ulta Beauty reported second-quarter fiscal 2026 results on Aug. 27, posting diluted earnings per share of $6.55 against a Wall Street consensus of roughly $6.17 to $6.20, a clear beat of about 38 cents. Revenue rose 8.9% year over year to about $3.04 billion, also topping the roughly $2.98 billion analysts expected, driven by comparable sales growth of 3.8%. Operating income climbed 10.1% to $379.6 million and net income totaled $282 million.

Management raised full-year guidance, projecting net sales growth of 6.7% to 7.2%, up from a prior 6% to 7% range, and lifted full-year diluted EPS guidance to $28.70-$29.00 from $28.36-$28.80. The beat came even as comparable-sales growth decelerated roughly 290 basis points from the year-ago quarter.

Despite exceeding estimates on both the top and bottom lines and raising its outlook, Ulta shares fell in after-hours trading, as investors focused on the slowing comparable-sales trend rather than the headline beat. The community was split evenly at 50% heading into the report, reflecting how close consensus estimates sat to what the company ultimately delivered.

The 2026 U.S. Open men's singles draw, released Aug. 27, placed Novak Djokovic in defending champion Carlos Alcaraz's half of the bracket, setting up a potential semifinal meeting rather than a final. The pairing shifted after Jannik Sinner withdrew from the tournament, which altered how the seeding rotation filled out each quarter under the standard draw procedure that separates the top seeds before working down the list.

Djokovic, a four-time U.S. Open champion, landed alongside Alcaraz's quarter, while top seed Alexander Zverev occupies the opposite half and would face the Djokovic-Alcaraz survivor in the final. Alcaraz enters as the two-time defending champion after winning the 2025 title, and the pair are close to even in their head-to-head series; Alcaraz won their lone 2026 meeting, at the Australian Open final.

The community forecast this correctly, with 59% predicting before the draw that Djokovic would land in Alcaraz's half, reflecting how the withdrawal of a top contender had already narrowed the field's likely bracket outcomes ahead of the official release.
