Summary.
The market is pricing Beth Van Duyne's chances of winning the 2026 Texas Republican Senate Primary at 0.15%, while the true probability is 0.0%. This is not a prediction—it's a retrospective fact: the Texas Republican Senate primary already occurred on March 3, 2026 (30 days ago), and Beth Van Duyne was definitively not a candidate. She instead ran for re-election to her U.S. House seat (TX-24), which she won uncontested. The Senate race has progressed to a May 26 runoff between John Cornyn and Ken Paxton. It is factually impossible for Van Duyne to win a race she did not enter and that has already concluded its initial voting. The residual 0.15% market price represents structural factors (minimum tick sizes, resolution risk premium, liquidity constraints) rather than any genuine probability of the event occurring. This market should resolve to NO with absolute certainty.
Reasoning.
This is a unique analytical situation where we have definitive, retrospective evidence that completely resolves the market question.
Temporal Context:
- Today is April 2, 2026
- The Texas Republican Primary for U.S. Senate occurred on March 3, 2026 (30 days ago)
- The market resolution date is May 26, 2026 (the runoff election date)
Key Evidence:
- Beth Van Duyne was NOT a candidate in the 2026 Texas Republican Senate Primary
- Van Duyne instead ran for re-election to her U.S. House seat (TX-24) and won an uncontested primary on March 3, 2026
- The Senate primary has already concluded with three major candidates: John Cornyn, Ken Paxton, and Wesley Hunt
- No candidate received >50%, triggering a runoff between Cornyn and Paxton on May 26, 2026
- Van Duyne cannot retroactively enter a race that has already occurred
Base Rate Analysis: The base rate for non-candidates winning elections is 0%. You cannot win a race you did not enter. This is not a probabilistic question—it's a factual impossibility.
Why the Market Shows 0.15%: The tiny residual probability (0.0015) in prediction markets for impossible outcomes typically represents:
- Extreme liquidity premium for taking on resolution risk
- Transaction costs and minimum tick sizes
- Theoretical possibility of catastrophic data errors
- Market microstructure (rounding, minimum prices)
Scenario Analysis: There is only one scenario: Beth Van Duyne did not run and cannot win. The 0.15% market price is purely structural/technical, not reflecting any genuine probability of the event occurring.
Conclusion: This market should resolve to NO with absolute certainty. The estimated true probability is 0.0% (or functionally 0% allowing only for truly bizarre resolution disputes that would themselves be errors).
Key Factors.
The primary election already occurred on March 3, 2026 (30 days ago)
Beth Van Duyne definitively did not run for U.S. Senate
Van Duyne ran for and won the House District 24 primary instead
The Senate race is in runoff phase between Cornyn and Paxton only
Candidate filing deadlines have long passed
Official primary results confirm Van Duyne was not on the Senate ballot
Scenarios.
Reality (>99.99% probability)
100%Market resolves to NO because Beth Van Duyne objectively did not run in the 2026 Texas Republican Senate Primary. She ran for House re-election instead. The primary already occurred on March 3, 2026, and she was not a candidate. The runoff is between Cornyn and Paxton.
Trigger: Already occurred. Official primary results from March 3, 2026 confirm Van Duyne was not on the Senate ballot.
Resolution Error Scenario
0%Market resolves incorrectly due to catastrophic administrative error, platform malfunction, or data corruption. This would be a mistake rather than Van Duyne actually winning.
Trigger: Would require complete breakdown of resolution process, contradicting all official Texas Republican Party records and credible reporting.
Van Duyne Wins
0%Impossible. You cannot win an election that already occurred if you were not a candidate. Van Duyne was confirmed to be running for House re-election, not Senate. The filing deadline has passed, the primary has occurred, and she was not on the ballot.
Trigger: No possible evidence exists because this scenario is factually impossible.
Risks.
Resolution process error (extremely unlikely but only non-zero risk)
Catastrophic data corruption affecting market resolution
Misinterpretation of resolution criteria by market operators
Platform technical malfunction during resolution
Edge Assessment.
MASSIVE EDGE: The market odds of 0.15% still overvalue this outcome. The true probability is effectively 0.0%. However, the edge is not practically exploitable because: (1) The 0.15% likely represents the minimum market price/tick size, (2) Capital efficiency is terrible when betting against 0.15% odds, (3) Counterparty availability may be limited, (4) The tiny edge doesn't overcome transaction costs and opportunity cost of locked capital until May 26 resolution. This is a case where the market is essentially correct (pricing it as impossible) but structural factors prevent it from reaching absolute zero. If you could bet NO at scale with minimal capital lockup, this would be +EV, but practically the edge is negligible given the structural constraints.
What Would Change Our Mind.
Discovery of credible evidence that Beth Van Duyne was actually on the March 3, 2026 Senate primary ballot (would contradict all current official records)
Texas Republican Party announcement of a completely new Senate primary that includes Van Duyne as a candidate (unprecedented and legally implausible)
Evidence that the March 3, 2026 primary results reported are fraudulent or will be completely invalidated
Clarification that the resolution criteria refers to a different election than the 2026 Texas Republican Senate Primary
Platform announcement of market resolution error or criteria change that would make YES outcome possible

9 or more upsets in 2026 March Madness Round of 64
The market is pricing 9+ Round of 64 upsets at 46% implied probability, treating 8 upsets as the most likely outcome. However, historical data (2010-2023) shows an average of 9.15 upsets per tournament under this broad definition (any lower seed defeating a higher seed), suggesting the true probability should be approximately 52%. The market appears to be overweighting 2025's extreme anomaly (only 3 upsets) while undervaluing the robust long-term average. Seed-by-seed analysis yields an expected value of 8.3 upsets, just below the threshold but well within normal variance. The broad upset definition critically includes 9-vs-8 matchups (four coin-flip games producing ~2 expected upsets), which creates a structural advantage for YES. While NIL and Transfer Portal talent concentration may be reducing upset rates, regular season data shows stable upset frequencies despite wider point spreads, suggesting tournament variance and single-elimination dynamics still dominate. Major uncertainty exists because Selection Sunday is March 15—just two days away—meaning specific bracket matchups, auto-bid quality, and injury situations remain unknown. The estimated 52% probability represents modest value against the market's 46%, but confidence is tempered (58%) by bracket unknowns and genuine uncertainty about whether 2025 signals a structural shift or statistical outlier.
Canadian team wins the Stanley Cup before the 2031 season
The market implies a 63% probability that a Canadian team wins the Stanley Cup between 2026-2030, but my analysis estimates a more conservative 52% probability—an 11-percentage-point overvaluation. This is essentially a bet on the Edmonton Oilers' championship window during Connor McDavid's prime (ages 29-33), as all other Canadian teams are non-competitive (Toronto/Vancouver rebuilding, Ottawa a longshot at +3300-4000). While McDavid's team-friendly extension through 2027-28 creates a legitimate 3-year window and the Oilers reached back-to-back Finals in 2024-2025, several factors suggest the market is overpricing this outcome: (1) Edmonton LOST both Finals, creating psychological hurdles that losing finalists historically struggle to overcome; (2) Current injuries are concerning—Leon Draisaitl has been out since March 15 with unclear playoff timeline, and McDavid has hip/groin issues; (3) Colorado upgraded to prohibitive favorite (+275-300) by acquiring Quinn Hughes; (4) The 2029-2030 seasons offer minimal value since McDavid's extension ends after 2027-28; (5) The market appears sticky at 63¢ despite recent negative developments, suggesting recency bias and McDavid halo effect rather than properly pricing injury risks and elite competition. My probabilistic model weights 2027-2028 as peak window years (12-15% each) but assigns only 6% to injury-plagued 2026 and 5% to uncertain 2030, yielding 52% cumulative probability.
Will humans colonize Mars before 2050?
The market is pricing a Mars colony by 2050 at 17.5%, but our analysis estimates just 3% probability—nearly a 6:1 mispricing favoring "No." The critical development is SpaceX's February 2026 strategic pivot to lunar colonization, explicitly delaying Mars missions by 5-7 years. This eliminates the only credible Mars settlement actor until the early 2030s, leaving merely 17-19 effective years for an unprecedented achievement requiring 15-20+ years minimum from today. The resolution criteria demands extreme technical sophistication: 10+ people surviving one full Earth year without resupply, requiring operational ISRU, radiation-shielded agriculture, manufacturing, and nuclear power. NASA's roadmap shows only exploratory missions (late 2030s/2040) with Earth resupply—no government agency has permanent Mars settlement planned. The market appears inefficiently high due to retail Musk enthusiasm not fully incorporating the recent pivot's implications, while sharp money is already favoring "No." The 24-year horizon creates false comfort; detailed milestone sequencing reveals timeline compression is nearly impossible given Mars's 26-month launch windows, 6-9 month transits, and self-sufficiency requirements. Only tail-risk scenarios (AI singularity enabling autonomous construction, or geopolitical space race) preserve ~3% probability.
