Sub-questions (Fermi decomposition)

Has Oura publicly or confidentially filed for an IPO (S-1 or draft), and what is the stated or reported timeline for listing before December 31, 2026?
What was Oura's most recent private valuation and revenue run-rate, and what IPO valuation range have bankers or reporters floated?
What is the base rate and typical magnitude of first-day price pops for large ($5B+) tech/consumer-hardware IPOs in 2024-2026, and how does that shift the distribution relative to the pricing valuation?
How does Polymarket's set of sibling market-cap bracket markets for Oura price the full distribution, and what implied probability is assigned to 'No IPO before January 2027'?
Are there indications Oura might delay or avoid an IPO (e.g., new private funding rounds, statements from CEO Tom Hale about staying private, market conditions)?
How will 'shares outstanding' be counted on the exchange listing page (basic vs fully diluted), and how much could that shift the reported market cap relative to headline valuation?

Planner reasoning

This is a conditional bracket question: it requires (a) Oura actually completing an IPO before 2027 and (b) the first-day closing market cap landing in a fairly narrow $12.5-15B band. Oura's last private round (Oct 2025) valued it near $11B, so the key research is whether an IPO is filed/planned, the likely pricing valuation, how the fully-diluted share count is defined, and base rates for first-day pops of large consumer-hardware/tech IPOs. The Polymarket price and sibling bracket markets are the primary anchor for the implied distribution.

# Current state Oura publicly filed its S-1 with the SEC on 2026-09-03 (confirmed) after a confidential draft filing in May 2026, targeting a Nasdaq listing under ticker "OURA." Reports (TechCrunch, Yahoo, Qz) indicate a possible September 2026 listing, raising up to $3B at a valuation exceeding $16B — above the $12.5B-$15B bracket this market asks about. Kalshi/Polymarket sibling markets currently price the $12.5B-$15B bucket well below several higher buckets, reflecting expectation the IPO will price/close above $15B. # Timeline of key events - 2026-05-21: Oura confidentially files draft IPO prospectus with SEC (confirmed, CNBC). - 2026-05-28: Oura launches smallest smart ring; reiterates no IPO timeline given (confirmed, CNBC). - 2026-08-24/25: Reports surface that Oura targets up to $3B raise at >$16B valuation, eyeing September IPO (reported, TechCrunch/Yahoo/Qz). - 2026-08-27: Prediction-market traders reportedly betting Oura lists above its $16B target (reported, Proactiveinvestors). - 2026-09-03/04: Oura publicly files S-1; discloses $1,214.5M revenue (9mo through June 2026, +74% YoY), 55% gross margin, $60.8M net income, $106.7M adj. EBITDA; underwriters Goldman Sachs, Morgan Stanley, JPMorgan, Allen & Co, Jefferies (confirmed, multiple outlets/ecmsource). - No confirmed pricing date or final valuation/share count as of latest research; IPO has not yet priced or begun trading. # Event Will Oura's market cap fall in the $12.5B-$15B bracket at close of its first trading day (else "No IPO before Jan 2027" if no IPO by 2026-12-31)? # Outcomes to forecast Yes / No (bracket-specific; part of an 8-way mutually exclusive Oura market-cap ladder plus "No IPO" outcome) # Kalshi market anchor Polymarket sibling contract (same ticker/question) YES = 23% currently (30-day change +12.5pp, range 4.5%-23%, volume $87,425). This is the most direct available anchor; no separate Kalshi-native price was returned for this specific ticker — kalshi_related only returned unrelated IPO-race markets (Ramp/Brex, OpenAI/Anthropic, Deel/Rippling), none priced Oura's cap directly. # Resolution source No resolution_source tool result provided; primary exchange listing page (Nasdaq, ticker OURA) will govern once IPO occurs. Not yet applicable — IPO has not priced/traded as of latest data. # Sub-question answers 1. **Filing/timeline**: Confidential draft filed May 2026; public S-1 filed Sept 3, 2026 for Nasdaq listing ("OURA"). No specific pricing/listing date confirmed; reports suggest a September 2026 target, but as of the S-1 filing no price range/share count was disclosed (finder.com, ecmsource.com). 2. **Valuation/revenue**: Last private valuation $11B (Sept 2025, $875M Series E). IPO chatter targets >$16B valuation, up to $3B raised. Revenue: $1,214.5M for 9mo ended June 2026 (+74% YoY vs $697.6M), $60.8M net income, $106.7M adj. EBITDA (ecmsource.com). Peer Whoop valued at $10.1B. 3. **First-day pop base rates**: 2025-2026 large tech IPOs averaging ~34% cap-weighted day-one pop (roughly double 2023-24 norms); examples: SpaceX +19%, Cerebras +68%. A ~20-30%+ pop on a $16B pricing would push close well above the $12.5B-$15B bracket. 4. **Polymarket sibling distribution**: Full ladder — <$7.5B: 0.25%, $7.5-10B: 0.35%, $10-12.5B: 3.25%, $12.5-15B: 23%, $15-17.5B: 29.5%, $17.5-20B: 15.5%, ≥$20B: 25.5%, "No IPO before Jan 2027": 2.6%. Market clearly weights outcomes above $15B most heavily (≈70% combined), consistent with the $16B+ pricing chatter and expected pop. 5. **Delay/avoidance signals**: None significant post-filing; Hale's Nov 2025 "no news on IPO" comment predates the May/Sept 2026 filings, which supersede it. No reports of a fresh private round or stated intent to stay private since filing. 6. **Share count methodology**: Not addressed in research; S-1 as filed did not disclose share count/price range, so no data on basic vs. fully diluted treatment yet — a real residual risk to precise bracket placement. # Key facts (high-confidence, factual) 1. [CNBC] Confidential IPO draft filed 2026-05-21. 2. [Multiple, ecmsource/Guardian] Public S-1 filed 2026-09-03; Nasdaq ticker "OURA." 3. [ecmsource] 9-month revenue $1,214.5M (+74% YoY), net income $60.8M. 4. [TechCrunch/Yahoo] Reported target valuation >$16B, raise up to $3B, possible Sept 2026 listing. 5. [Polymarket] Sibling markets price ≥$15B buckets cumulatively ~70%; $12.5-15B bucket at 23%. # Cross-market signals - Kalshi related: No direct Oura market-cap pricing found; adjacent IPO-race markets (Ramp/Brex, OpenAI/Anthropic) irrelevant to valuation level. - Polymarket: Same-question market at 23% YES; full ladder shows market leaning toward $15B+ outcomes (see above). - Sportsbook implied: N/A. # Analyst opinions and speculation - Proactiveinvestors (2026-08-27): prediction-market traders reportedly betting Oura will list *above* its $16B target. - Code-execution model (lognormal pop simulation): conditional probability of closing in $12.5-15B given IPO occurs ≈ 12-17%; unconditional (factoring IPO-occurrence probability) central estimate ≈ 7-9%. # Directional lean per outcome - **Yes ($12.5-15B)**: Supported only if IPO prices conservatively (~$11-12B) with muted/negative first-day pop; opposed by strong reported $16B+ pricing target, historically large 2025-26 pops (~20-34% median), and Polymarket ladder weighting mass above $15B. - **No**: Favored — either IPO completes with close above $15B (most likely per reports/model) or below $12.5B/no IPO (low probability). Polymarket implies ~77% No. # Gaps / unknowns - No confirmed price range, share count, or listing date yet (S-1 amendments pending). - No Kalshi-native price for this exact ticker; relying on Polymarket cross-market and model estimate. - Fully diluted vs. basic share count treatment on listing page unresolved — could shift market cap materially at the margin. - No signal of delay/withdrawal since Sept 2026 S-1 filing. # Calibration anchors - Polymarket YES (cross-market proxy) = 23%; model-derived unconditional estimate ≈ 7-9% (lower than Polymarket, reflecting model's emphasis on likely pop pushing above bracket). - Precedent: SpaceX (+19%), Cerebras (+68%) day-one pops in 2026 IPO wave — suggests high likelihood valuation clears bracket if $16B pricing holds.

The most direct anchor is the Polymarket sibling contract at 23% YES, with ~70% of the ladder mass above $15B. Reports peg the IPO target at >$16B with up to $3B raised, and 2025-26 large tech IPOs have averaged ~20-34% day-one pops (SpaceX +19%, Cerebras +68%), which would push the close well past $15B if the $16B pricing holds; a lognormal model puts the bracket at only ~7-17%. However, the S-1 has no price range or share count yet, and listing-page market caps often use basic rather than fully diluted shares, so a $16B fully-diluted valuation with a muted debut could plausibly register in the $12.5-15B range — a real path to Yes that keeps me near the market. I shade slightly below the Polymarket price toward the model estimate given the strong pop base rates and above-target pricing chatter.

Oura has publicly filed its S-1 (Sept 3, 2026) with reported targets of a >$16B valuation and up to $3B raised, so the base case is a pricing already above the $12.5B-$15B bracket, and 2025-26 large tech IPOs have averaged ~20-34% day-one pops (SpaceX +19%, Cerebras +68%), which would push the close further above $15B. The Polymarket sibling ladder prices this bucket at 23% with ~70% mass on $15B+ buckets, while a lognormal pop model gives only ~7-9% unconditional. Paths to Yes require a conservative price range (~$12-13B basic cap) with a muted or negative pop, or a basic-vs-fully-diluted share count gap that shaves the listed cap below $15B despite a $16B headline valuation — plausible but minority scenarios. No price range or share count is disclosed yet, so I shade modestly below the Polymarket anchor toward the model estimate.

42% conf

Yes	21%
No	79%

The most direct anchor is the Polymarket sibling contract at 23% YES, with the ladder placing ~70% of mass above $15B, consistent with reports (TechCrunch/Yahoo) of a >$16B target valuation and a 2025-26 IPO wave averaging ~20-34% day-one pops (SpaceX +19%, Cerebras +68%). The brief's lognormal model puts the unconditional bracket probability at only 7-9%, but two unpriced-in-model risks cut toward Yes: IPO targets often get trimmed at pricing, and the listing page may report basic rather than fully diluted share count, which could knock a $16B headline valuation down toward the $13-15B range. No price range or share count has been disclosed yet, and IPO non-occurrence risk is small (~3%). I land slightly below the Polymarket price, at 21% Yes.

Yes	17%
No	83%

The direct Polymarket proxy prices Yes at 23%, providing the primary consensus anchor. Oura's public S-1 and strong financials make a 2026 IPO likely, but reports of a targeted valuation above $16B already place it beyond the specified bracket. Recent large-tech IPO first-day gains averaging roughly 34% further favor a closing market cap above $15B, while the missing price range and share count leave meaningful uncertainty. I therefore move below the 23% anchor, though not as low as the model's 7-9% estimate because final pricing could still be conservative or trading could disappoint.

gpt-5.6-sol

70% conf

Yes	20%
No	80%

The direct Polymarket sibling contract anchors Yes at 23%, while its full ladder assigns about 70% to first-day market caps above $15B. Oura's public S-1, rapid 74% revenue growth, profitability, and reported target valuation above $16B support an IPO close above the bracket, especially given recent large-tech IPO first-day pops. The completed filing and lack of new delay signals make failure to list a relatively minor component of No. I shade Yes below the market anchor to 20% because both the reported valuation target and the 12-17% conditional model estimate indicate that landing specifically within this narrow bracket requires notably conservative pricing or weak first-day trading.
