Resolves Oct 28, 2026 · October FOMC decision

Today's (Oct 27) check, one day before the decision, found the picture still frozen in blackout: markets broadly expect a hold, with CME FedWatch-style readings clustering in the high-70s to low-80s percent for no change (roughly 15-18% for a hike), essentially unchanged from the Oct 16-20 picture built around Warsh's 'I don't prejudge meetings' remark in Bangkok. No policymaker can speak publicly before tomorrow's 2pm ET decision. The hawkish case still rests on Barr's pre-blackout base case for a further hike, Cleveland Fed's Hammack signaling openness to another increase, and 16 of 18 September dots penciling in more tightening this year, while the dovish case leans on September's weak 29K payrolls print, MUFG's explicit skip call tied to the Nov 3 midterms' proximity, and the post-CPI inflation scare having faded rather than built into decision week.

Where consensus sits

14% yes — The Fed hikes again

Holding near a cycle-low hike probability (~14-18%) the day before the decision — in blackout with no fresh catalyst, the number has barely moved since Warsh's Oct 16 silence removed the last pre-decision chance for a hawkish surprise

The hawkish case got fuel from the Oct 14 CPI print: headline inflation accelerated to 3.7% y/y (above forecast) and core also ran hot at 2.6% y/y, Barr's base case already included a further hike, Cleveland Fed's Hammack has separately signaled openness to another increase, and 16 of 18 dots pencil in more hikes this year. The dovish case: September payrolls missed by roughly 55-60K with a rising unemployment rate and downward revisions, MUFG's house call explicitly expects a skip given proximity to the Nov 3 midterms, and market-implied odds have held near a cycle-low hike probability of roughly 13-17% with the inflation scare having faded rather than built into decision week.

Resolves Nov 3, 2026 · 2026 US Senate midterm election day

Today's (Oct 27) check, one week out, still leans on race-by-race ratings rather than market pricing: Cook Political Report's Oct 26 update continues to frame Republicans as holding the overall structural advantage even as it counts seven toss-ups (six Republican-held, one Democratic-held) and has drifted Georgia, North Carolina and Ohio toward Democrats since August. Cook itself projects a net Democratic gain of 2-6 seats this cycle against the 4 needed for control — a range that straddles the control threshold rather than clearly resolving it. Nate Silver's statistical model, last updated in September, remains the most conservative credible estimate on file at 58.6%, up from 50.6% on Sept 6. No fresher individual-race polling was found than the NYT/Siena picture already on record (six Republican-held seats within three points, including a now-even Texas race between Democrat James Talarico and Republican Ken Paxton), and Maine's Democratic nominee is reported inconsistently across outlets (Troy Jackson vs. Graham Platner), a reminder of how thin some of this race-level coverage still is a week out.

Where consensus sits

60% yes — Democrats win the Senate

A genuine toss-up tilting narrowly Democratic — Cook's own seat-gain range (2-6) straddles the 4-seat control threshold, and Silver's cooler 58.6% model pulls the number down from the more bullish race-rating momentum

The case for Democratic control: Cook Political Report has moved Texas, Iowa and Ohio into toss-up territory and Georgia and North Carolina to lean-Democratic since August, Michigan looks solidly blue on every tracker, and a generic midterm swing against the governing party is a well-documented historical pattern. The case for Republican control: Cook itself still frames Republicans as holding the overall advantage and its own projected seat-gain range (2-6) only sometimes clears the 4-seat threshold Democrats need, Nate Silver's model runs noticeably cooler than the race-rating momentum at 58.6%, individual-race aggregators still disagree by double digits on Maine and Texas, and seven toss-ups by definition could break either way on election night.

No fixed date · No exchange-confirmed listing date exists; OpenAI confidentially filed a draft S-1 around June 2026 and has been reported eyeing a listing between late 2026 and 2027, but has set no public target date

Today's (Oct 27) check found the same picture, reinforced rather than changed: CFO Sarah Friar's August all-hands framing — public 'in 2027, or sooner' only if the business keeps inflecting — remains the most explicit internal timeline on file, consistent with Altman's Sept 12 Fortune interview explicitly ruling out 2026 and calling a near-term listing 'ill-advised' given AI-safety concerns. Anthropic, OpenAI's closest IPO-race peer, is now reported targeting formal marketing as early as the week of Nov 9 with a debut before Thanksgiving — underscoring that OpenAI itself expects to list second. OpenAI completed its for-profit recapitalization into OpenAI Group PBC in October 2025, with the nonprofit OpenAI Foundation retaining roughly 26% control and the prior cap on investor returns removed — the main structural prerequisite for a conventional IPO remains in place. No public S-1 has yet appeared on EDGAR and no exchange has confirmed a listing date.

54% yes — OpenAI completes a US IPO

Nudged down again — nothing has moved the 2027-or-later timeline, and Anthropic's firming Nov 9 marketing start keeps reinforcing OpenAI's position as the slower, more hesitant mover

The case for completing an IPO: the October 2025 restructuring removed the old profit-cap obstacle, OpenAI itself confirmed a confidential S-1 filing, Microsoft and other large investors have a direct financial incentive to see a liquidity event, and the company has never disavowed going public eventually, only the near-term timing. The case against, or for a long delay: Altman has now explicitly ruled out 2026 and cited AI-safety concerns as a reason to hold back, a separate NYT-sourced account says he's also holding out for a $1 trillion valuation floor and rejected listing sooner at a lower price, OpenAI's spokespeople have separately said 'an IPO is not our focus' and that the company could not possibly have set a date, the company's unusual nonprofit-controlled governance could still complicate conventional public-market scrutiny even post-restructuring, and mega-cap tech IPO timelines in this cycle (including this one) have now slipped more than once.

Resolves Nov 14, 2026 · PDUFA target action date for Summit Therapeutics' BLA covering ivonescimab plus chemotherapy in previously treated, EGFR-mutated non-small-cell lung cancer, based on Phase 3 HARMONi trial data

Today's (Oct 27) check again found no newer reporting than the Fierce Pharma update already on file — Summit's newest OS analysis (data cut June 2026) still stands as the latest data point, putting the Western-subgroup hazard ratio at 0.76 (improved from 0.84 and 0.98 at earlier cuts) but still described as not reaching statistical significance, with the update itself carrying real risk of a major-amendment review extension that could push the actual decision past the Nov 14 date this question resolves against. With 18 days left until Nov 14, no extension has been formally confirmed either way, and the file remains in its routine pre-decision quiet period.

35% yes — FDA approves ivonescimab

Tilting against approval by the Nov 14 date — the newest Western-subgroup OS analysis (HR 0.76) is again described as not statistically significant, and the update itself raises real risk of a major-amendment review extension that would push any decision past this question's own deadline

The case for approval by Nov 14: HARMONi met its primary endpoint (progression-free survival) back in 2024, the OS hazard ratio has improved with each successive data cut (0.98 to 0.84 to 0.76), the related HARMONi-2 trial's clearly significant OS win over Keytruda feeds broader confidence in the molecule's underlying mechanism, and Summit has kept engaging the FDA with updated data rather than withdrawing the filing. The case against: the FDA specifically told Summit a statistically significant OS benefit was required and the latest cut still doesn't clear that bar per Fierce Pharma's reporting, the Nov 14 filing rests on HARMONi (not the stronger HARMONi-2 data), the newest analysis plausibly constitutes a major amendment that could trigger a three-month review extension — meaning even a drug the FDA ultimately approves could still resolve 'no' against this specific by-date question — and a comparable prior precedent (Eli Lilly's 2022 CRL for a China-only PD-1 trial) shows the FDA's skepticism toward single-region trial data generally.

Resolves Oct 30, 2026 · BOJ Monetary Policy Meeting decision (Oct 29-30, 2026), announced Oct 30

Today's (Oct 27) check, 3 days out, found the same low-probability picture holding: BBH's Oct 19 swaps-based read of under 5% for an Oct 30 hike (and roughly 80% for the Dec 18 meeting) remains the freshest number on file, with no newer swaps print surfacing today. USD/JPY has been range-bound near 152 this week per FXStreet's Oct 22 note, consistent with markets treating Wednesday-Friday's decision as a likely formality. Tokyo core CPI's jump to 2.7% y/y in September (from 1.8%) remains the one hot data point keeping a tail risk of a hawkish surprise alive, but Ueda has given no explicit guidance toward an October move, and a former BOJ official continues to call a January hike more likely than October.

Where consensus sits

12% yes — BOJ hikes in October

Holding near a cycle-low level three days out — the freshest swaps read (BBH, under 5%) is the most dovish on file, with the still-unresolved spread between that and the older ~26% futures-based reading left unreconciled by any new data this week

The case for an October hike: Tokyo core CPI's jump to 2.7% y/y in September adds fresh fuel, Ueda's Sept 18 hike (7-2 vote) shows the Board has the votes to act again quickly, and Ueda himself has warned of yield-curve risk if the Bank is seen moving too slowly. The case for a hold: the most recent swaps readings sit well below last month's levels, a former BOJ official's own house view still points to January as the more likely next move, two Board members already dissented in September, and a December-or-later hike is already heavily priced regardless of what happens this month, reducing the Bank's urgency to act again just six weeks after its last increase.

Resolves Nov 1, 2026 · OPEC+ Nov 1, 2026 meeting, where the group decides December output policy

Today's (Oct 27) check found no new wire reporting beyond what's already on file — the Oct 4 decision to hold November's combined quota unchanged at 31.01 million bpd stands as the latest concrete data point, with UBS analyst Giovanni Staunovo's 'market remains tight' framing still the most recent read on sentiment. The group wants its broader capacity review in hand before resuming increases — a review Iran-war-related disruptions have already delayed once — and Gulf producers are still pumping well below even the unchanged quota amid continuing export disruptions. The Nov 1 meeting, where the group reviews market conditions for December, is now 5 days away. Brent crude remains elevated above $100/barrel, up from roughly $73 before the Iran war began in late February.

35% Oct 8, 202621% Oct 27, 2026

Where consensus sits

21% yes — OPEC+ raises the December target

Nudged lower again toward a third straight pause — nothing new surfaced today, and the lack of any fresh bullish signal with the meeting days away reinforces the existing pause lean

The case for a December hike: Brent above $100/barrel gives the group room to add nominal barrels without necessarily crashing prices, Saudi Arabia's documented 2025 strategy of phased increases to regain market share remains the group's broader backdrop once it judges the supply picture safe, and a token December increase could be used to signal confidence ahead of the delayed 2027 capacity review. The case for another pause: the group has already paused twice in a row citing oversupply-glut concerns, a near-identical pause decision last November (for Q1 2026) shows the group is willing to hold steady for an extended stretch rather than resume increases after just one or two months, and Gulf producers are already pumping below even today's unchanged quota because of Iran-war-related export disruptions, leaving little practical reason to raise the nominal target further right now.

Resolves Dec 12, 2026 · Status of federal appropriations the morning after the Dec 11, 2026 continuing-resolution deadline (H.R. 6500)

Today's (Oct 27) check found Congress still in its pre-midterm posture with no new floor action to report: the Senate Appropriations Committee remains deadlocked along party lines with zero of the twelve FY2027 bills finalized, and House Appropriations Chairman Tom Cole's warning that there isn't enough time left before December stands unchallenged. A bipartisan Senate push — the Lankford-Hassan 'Prevent Government Shutdowns Act,' which would impose an automatic 14-day rolling continuing resolution on any future lapse — remains only a bill, with no sign it could pass and take effect before this December's deadline. The government has already lapsed into a shutdown twice in the prior 13 months (a 43-day shutdown in fall 2025 and another lapse in early 2026), underscoring how real the risk is even with members of both parties publicly campaigning on having 'kept the government open' in September. With Nov 3 midterms now just one week away, Congress has little incentive to negotiate seriously on FY2027 funding before voters go to the polls.

Where consensus sits

36% yes — A shutdown is in effect on Dec 12

Nudged slightly higher — the Senate deadlock remains total with six weeks to the deadline, and the one new legislative fix in play (automatic-CR bill) has no realistic path to enactment before December 11

The case for a shutdown: the Senate Appropriations Committee remains fully deadlocked along party lines with none of the twelve FY2027 bills finalized, Chairman Cole has publicly said there isn't enough time to complete the bills before December, the government has already lapsed into a shutdown twice in the prior 13 months, and the Nov 3 midterms will have just passed, removing the main electoral incentive either party had to avoid a shutdown this time. The case against: the September stopgap passed with overwhelming bipartisan margins (90-6 in the Senate, 370-48 in the House), showing both parties have repeatedly preferred a continuing resolution over a lapse, the House has already passed three of the twelve full-year bills, and members of both parties have publicly taken credit for 'keeping the government open,' suggesting neither side wants to be blamed for a holiday-season shutdown.

Resolves Oct 28, 2026 · Microsoft fiscal Q1 2027 earnings release, after market close

Tomorrow (Oct 28) after market close is the decision point, one day away. Microsoft confirmed on Oct 7 that it will report fiscal Q1 2027 results then. Back in July, management guided to roughly $50 billion in capex (including finance leases) for the quarter — below the $56.02 billion Visible Alpha consensus at the time — after changing how it accounts for data-center leases (spreading them over 25 years instead of 15), which mechanically lowers reported capex. Sell-side estimates for full fiscal-2027 capex have since run well above the company's own framing: Wolfe Research raised its FY27 capex forecast to $270 billion from $230 billion citing rising AI-memory costs, Truist models $252 billion, and the broader Street consensus sits near $233 billion. Reinforcing the beat case, Microsoft's prior quarter (fiscal Q4 2026, reported in July) saw Azure growth of 43% topping the 39.98% Visible Alpha consensus, a reminder that the company has recently beaten Street modeling on both growth and spend even under cautious guidance.

Where consensus sits

57% yes — Capex beats the Street estimate

Leaning slightly toward a beat heading into tomorrow's print — the pattern of Microsoft outrunning its own cautious guidance (as Azure did last quarter) and the Street's upward capex revisions tilt this a bit past a coin flip

The case for a beat: AI-chip and data-center demand has repeatedly outstripped supply this cycle, Wolfe Research and Truist have both revised their fiscal-2027 capex models higher (to $270B and $252B respectively) citing rising memory costs, and Microsoft has a history of under-promising on quarterly capex only to spend more as GPU allocations and power deals materialize faster than planned. The case for a miss (at or below the $50B guide): management explicitly guided to that lower figure in July after the lease-accounting change, the new 25-year lease amortization mechanically reduces reported capex versus the old methodology, and Microsoft's own CFO commentary has stressed capital discipline amid investor pushback on the pace of AI spending across the sector.

No fixed date · FTC filed its notice of appeal Jan 20, 2026 (D.C. Cir. No. 26-5028); briefing is well advanced with the FTC's reply brief filed Sept 29, 2026, but no oral-argument date has been set

Today's (Oct 27) check confirmed the same briefing timeline already on file via the D.C.

25% yes — DC Circuit revives the FTC's case

Leaning toward affirmance — Boasberg's findings came out of a full bench trial, and appellate courts generally defer to a trial court's factual findings absent clear error, making a full reversal a genuine uphill climb for the FTC

The case for reviving the claims (yes): the FTC's own reply brief argues the district court applied the wrong legal standard by requiring proof of ongoing monopoly power rather than monopoly power at the time of the challenged conduct, a purely legal question the D.C. Circuit reviews without the usual deference given to factual findings, and the Trump administration's FTC has continued pressing the appeal rather than settling or dropping it. The case for affirmance (no): Boasberg's ruling followed a full bench trial with detailed factual findings on market definition and competitive dynamics, the Washington Legal Foundation and other amici argue the district court's legal analysis was sound, and federal appellate courts have historically been reluctant to overturn well-reasoned bench-trial antitrust rulings on the merits.

No fixed date · Commerce's required update on domestic copper markets was due by June 30, 2026 and reportedly recommended a phased tariff (15% rising to 30%); as of September 2026 reporting the White House had made no final decision, and no proclamation has been issued as of this run

The original July 2025 Section 232 proclamation imposed a 50% tariff on semi-finished copper products but carved out refined copper (including cathodes) pending a separate Commerce review. That review recommended a phased universal duty — 15% starting January 1, 2027, rising to 30% in 2028 — but Reuters reported on Sept 10, 2026 that the White House's plan had 'stalled amid affordability concerns,' with an administration official saying no final decision had been made. Freeport-McMoRan's CEO said as recently as this cycle that the company is still waiting for tariff details; Freeport itself didn't push a specific recommendation in its Commerce survey response, while Trafigura urged keeping refined copper tariff-free until new US capacity comes online and the Copper Development Association sought exemptions. When the hesitation story broke, Freeport shares fell about 7% and copper prices eased, underscoring how much is actually priced on this decision.

Researched Oct 27, 2026 · tracked since Oct 27, 2026

Where consensus sits

20% yes — Trump imposes the refined-copper tariff

Leaning no — a market-based read (the COMEX-LME price spread) implies only a mid-teens probability for the January 2027 duty, consistent with Reuters' reporting that the plan has stalled inside the White House over affordability concerns

The case for a tariff: Commerce's own mandated review recommended the phased duty, the administration has shown a consistent preference for using Section 232 to reshore metals production, and domestic smelters/recyclers have an obvious profit incentive to lobby for it. The case against: Reuters reports the White House itself has stalled the plan over consumer-affordability concerns, Société Générale's analysis of the COMEX-LME copper price spread implies only a 14.6% market-priced probability of the 15% tariff taking effect in January 2027, and major industry voices (Freeport, Trafigura, the Copper Development Association) have either declined to lobby for it or actively argued against immediate implementation.

No fixed date · The three agencies re-proposed the rule on March 19, 2026; the public comment period closed June 18, 2026; Bloomberg Intelligence has projected possible finalization in late 2026 with phase-in from 2027, but no agency has set a public target date

Federal banking regulators re-proposed Basel III Endgame on March 19, 2026, describing it as the most significant reset to the capital regime in more than a decade, with lower minimum risk weights, less conservative methodologies and a narrower market-risk framework expected to reduce overall capital requirements industry-wide — a sharp contrast to the original 2023 version, which raised requirements and drew heavy bank opposition before stalling for years. The public comment period closed June 18, 2026, and Fed Governor Michelle Bowman has said changes to capital rules are 'coming soon,' but no agency has committed to a specific finalization date. No final rule had been issued as of this run.

Researched Oct 27, 2026 · tracked since Oct 27, 2026

Where consensus sits

60% yes — Regulators finalize the rule

Leaning toward eventual finalization — this version lowers rather than raises capital requirements, giving regulators and banks aligned incentives to finish it, but the original proposal's multi-year stall is a real precedent for delay

The case for finalization: this re-proposal is explicitly bank-favorable (lower capital requirements rather than higher), removing the intense industry opposition that stalled the 2023 version for years, Governor Bowman has publicly signaled the agencies intend to move soon, and the comment period has already closed. The case against, or for further delay: the original 2023 Basel III Endgame proposal took more than two years and was ultimately scrapped rather than finalized in its original form, the UK has already pushed back its own Basel timeline specifically citing US delay as the reason, and no agency has committed to any public target date even four months after the comment period closed.

Resolves Mar 3, 2027 · PDUFA target action date for Exelixis's NDA covering zanzalintinib plus atezolizumab in previously treated metastatic colorectal cancer, based on Phase 3 STELLAR-303 data; extended three months from the original Dec 3, 2026 date after the FDA requested updated efficacy and safety data

The FDA accepted Exelixis's NDA for standard review on Feb 2, 2026, based on the Phase 3 STELLAR-303 trial, which showed zanzalintinib plus atezolizumab improving overall survival over regorafenib (stratified hazard ratio 0.80; median OS 10.9 vs. 9.4 months) in previously treated, non-MSI-high metastatic colorectal cancer. On Sept 11, 2026, Targeted Oncology reported the FDA extended the PDUFA date by three months, to March 3, 2027, to review updated efficacy and safety data Exelixis submitted — the agency gave no public reason beyond needing more time. The trial missed significance on one of its dual primary endpoints in a subgroup, and severe or life-threatening adverse events occurred in 59% of the zanzalintinib arm versus 37% on regorafenib. William Blair's analysts have characterized overall rejection risk as low given the broadly positive data, while Leerink has flagged a risk the FDA could carve out the non-liver-metastatic subgroup from any approval.

Where consensus sits

55% yes — FDA approves zanzalintinib for mCRC

A genuine coin-flip-adjacent call — sell-side analysts see low rejection risk on the merits, but the FDA's own three-month extension to request more data is a real cautionary signal that keeps this from being a clear 'yes'

The case for approval: STELLAR-303 showed a statistically significant overall survival benefit in its primary analysis, William Blair's analysts believe rejection risk remains low given the broadly positive data, and Exelixis changed nothing about the underlying trial results when the FDA asked for updated data. The case against: the FDA's extension request itself signals unresolved questions, the trial missed statistical significance on a dual-primary-endpoint subgroup analysis, severe adverse events ran notably higher on zanzalintinib (59%) than on regorafenib (37%), and Leerink has flagged a real risk the agency excludes the non-liver-metastatic subgroup from any approved label.
