This is a barrier-crossing question on the 10-year Treasury yield: it resolves YES if the daily Treasury par yield ever prints ≥5.00% between Nov 11 2025 and Dec 31 2026. The key inputs are the current level and distance to the barrier, realized/implied volatility of the 10y yield (base rate for an ~80-90bp upward excursion over ~14 months), and macro drivers (Fed path, inflation expectations, term premium/fiscal supply, Fed chair succession). The Polymarket price is the primary anchor, with Kalshi's ladder markets on 10y yield as a cross-venue check.

# Current state The 10-year Treasury yield (DGS10) is at ~4.65-4.70% as of Aug 7-11, 2026, roughly 30-35bp below the 5.00% threshold, with the window closing Dec 31, 2026. Recent trajectory has been upward (July 2026 high of 4.75%), driven by rising term premium, oil-driven inflation concerns, and market skepticism toward new Fed Chair Kevin Warsh — but no bank base case currently forecasts a full breach of 5.0% by year-end. # Timeline of key events - 2023-10: 10y yield peaked at ~5.02% (historical high-water mark referenced in question).

[FRED DGS10, confirmed] # Event Will the 10-year Treasury yield reach ≥5.00% on any date between Nov 11, 2025 and Dec 31, 2026? # Outcomes to forecast Yes / No (binary) # Kalshi market anchor No kalshi_direct price was returned for this ticker in research (data gap). The only Kalshi data available is unrelated Fed-funds-rate-2034/35/36 markets (kalshi_related), not usable as a direct anchor. Polymarket price for the identical question is the best available cross-market anchor: **33% YES**, up +11.5% (7d) and +24% (30d), range 7.5%-35.5% over 90 days — strong recent upward momentum. # Sub-question answers 1. **Current level vs 5.00%:** 10y at ~4.65-4.70% (Aug 2026); ~30-35bp shy of threshold. [FRED DGS10] 2. **Historical base rate for a ~30-35bp move (note: not 90bp — model tool mis-set distance at 90bp assuming 4.10% start, but actual gap is much smaller ~30bp):** Code-execution tool modeled a 90bp barrier at 32-34% (range 15-55% depending on vol regime); since actual required move is only ~30bp, true probability is materially higher than this model output. 3. **Highest print since Oct 2023 peak (~5.02%):** July 31, 2026 print of 4.75% is the highest cited 2026 level; 30-year yield near 5.2% in same period. [forbes.com, morningstar.com] 4. **Fed path / term premium correlation:** Fed funds effective rate flat at 3.63% (DFF, Aug 2026); term premium (THREEFYTP10) rising from ~0.78 (mid-July) to ~0.87 (July 31), consistent with rising 10y despite stable/cutting front-end — term premium expansion, not policy rate, is driving long yields. [FRED] 5. **Inflation expectations:** T10YIE (breakeven) stable ~2.22-2.29% in early Aug 2026, not signaling acceleration; core PCE cited at 2.8%, above target. [FRED, financialcontent.com] 6. **Fiscal/institutional risk:** National debt at $38.6T (Feb 2026) after fiscal stimulus bill; Fed independence concerns post-Warsh appointment; bond market "unimpressed" by Warsh, pushing 30y toward 5.2%. [financialcontent.com, brookings.edu, fool.com] 7. **Cross-venue pricing:** Polymarket at 33% YES with strong upward momentum; no independent Kalshi price found for direct comparison — data gap. # Key facts (high-confidence, factual) 1. [FRED] 10y at 4.65-4.70% as of Aug 7-11, 2026. 2. [FRED] Term premium (THREEFYTP10) rose from 0.78 to 0.87 over ~2 weeks in late July 2026. 3.

[forbes.com] July 31, 2026 10y print of 4.75% is 2026's high so far. # Cross-market signals - Kalshi related: only distant-year Fed funds rate markets found; no direct 10y-yield comparable priced. - Polymarket: 33% YES, sharply rising (+24% in 30d), suggesting growing conviction toward Yes. - Sportsbook implied: N/A (not applicable to this market type). # Analyst opinions and speculation - JPMorgan raised year-end 10y target to 4.85% (up from 4.70% base case); Goldman, Morgan Stanley, Barclays reportedly similar. [bitget.com] - Morgan Stanley IM sees 4% as floor, not ceiling threat. [mexc.com] - Capital Group/Schwab see range-bound 3.75-4.50%, flagging fiscal/term-premium/oil as upside risks but not base-case breach of 5%. [capitalgroup.com, schwab.com] - Seeking Alpha flags a "major breakout" possibility if term premium reverts to historical norms. [seekingalpha.com] # Directional lean per outcome - **Yes**: Only 30-35bp away from threshold with ~5 months remaining; term premium rising; 30y already near 5.2%; Fed independence concerns; hawkish JPMorgan revision to 4.85%; Polymarket pricing rising fast. - **No**: Majority of bank forecasts (JPMorgan base, Morgan Stanley, Capital Group, Schwab) still see year-end 10y below 4.85-4.90%; breakevens stable, no inflation re-acceleration signal; Fed funds rate steady/no hiking pressure. # Gaps / unknowns - No Kalshi-direct price available for this specific ticker — primary anchor missing. - Unclear exact trading path Sept-Dec 2026; only data through Aug 11, 2026 provided (~5 months of window remain). - Code-execution model used incorrect starting yield assumption (4.10% vs actual 4.65-4.70%), understating true proximity to threshold. # Calibration anchors - Polymarket YES price (33%, rising) — best available direct proxy anchor given missing Kalshi price. - 10y sits only ~30bp below the Oct 2023 cycle high (~5.02%), a level already tested once in the past 3 years — supports meaningfully >33% probability given only ~5 months remain in a rising-term-premium environment.

1. Both forecasters anchor heavily on Polymarket's 33% and nudge modestly upward, but neither seriously engages with Forecast 1's own barrier-touch model output of 45-55% — a max/one-touch probability that is mechanically far more relevant than a point-in-time year-end forecast (bank targets like JPMorgan's 4.85% describe year-end levels, not the max reached during the window), so both may be under-weighting the "ever touches 5.0%" framing versus "ends near 5.0%." 2. Neither forecast adjusts sufficiently for the fact that the 30-year is already at ~5.2%, and historically the 10y/30y spread compressing or the curve bull-flattening could pull the 10y toward the 30y faster than a naive vol model suggests; this cross-tenor signal is treated as a minor bullet rather than a structural indicator that long-end pressure is already present. 3. Both treat Polymarket's 33% as a reasonably clean "cross-market anchor" without discounting for its known biases (thin liquidity, retail-driven momentum, no arbitrage against Kalshi confirmed) — given the brief explicitly flags this as a data gap with no Kalshi-direct price, both should have expressed more uncertainty around how much weight to place on 33% versus their own vol-based models. 4. The brief notes the code-execution model mis-set the barrier distance (90bp vs actual 30bp), explicitly stating "true probability is materially higher than model output" — Forecast 1 references this correction but arguably still under-corrects, landing only 5pp above Polymarket despite acknowledging a driftless model implies 45-55%; Forecast 2 doesn't engage with this correction at all. 5. Neither forecaster explores tail/catalyst scenarios (e.g., a fiscal crisis, credit rating downgrade, disorderly Fed-independence episode under Warsh, or oil shock reacceleration) that could cause a fast 30bp+ move — given $38.6T debt and explicit "Fed independence concerns," these low-probability/high-impact paths deserve more than passing mention, especially since only a modest breach (touching 5.00% even briefly) is needed for YES. 6. Both converge suspiciously close (38% vs 43%) despite using different reasoning weights, which may reflect anchoring on each other's plausible range rather than independently reconciling the barrier-model math (45-55%) with the fundamentals-based skepticism (bank forecasts <4.90%) — a wider spread or more explicit reconciliation of these two conflicting evidence classes would be more informative.

43% (medium confidence)

Yes: 43% No: 57%

The mechanically correct framing is a one-touch barrier problem: with the 10y at ~4.65-4.70% and only ~30-35bp to 5.00% over ~4.7 remaining months, a driftless random walk with 60-80bp annualized absolute yield vol implies roughly 39-52% touch probability, and the mildly upward drift implied by revised bank targets (JPMorgan 4.85%) nudges that higher rather than lower. The critique is right that bank year-end point forecasts below 4.90% are only weak evidence against an intra-period touch, and that the 30y already near 5.2% plus an expanding term premium (0.78→0.87) show long-end pressure is already present. Offsetting: stable breakevens (~2.25%), a steady 3.63% fed funds rate, and the fact that repeated tests of 4.75% have so far been met with buyers argue against a clean breakout, and the Polymarket 33% (albeit thin, momentum-driven, and unconfirmed by Kalshi) carries some information. I therefore land above both the 33% anchor and Forecast 1, close to Forecast 2 but slightly higher, at 43% Yes — between the pure barrier math and the fundamentals-based skepticism.
