Tony Evers for 2028 Democratic VP nominee

Step 1: Base Rate Analysis

Historical VP selection patterns over the past 50 years provide a strong foundation:

• Active officeholders at time of selection: >90%
• Retired politicians selected as VP: <5%
• VP nominees over age 70: 1-2% (extremely rare in modern era)
• Candidates retired and out of office 18+ months before campaign: 0%

For someone matching Evers' profile (retired, 77 years old, out of office 18+ months), the combined base rate is effectively 0%. This establishes a starting probability of approximately 0.1-0.3%.

Step 2: Specific Situational Adjustments

Negative factors (reducing probability):

1. Retirement announcement: Evers explicitly chose not to seek re-election, signaling withdrawal from active politics
2. Age (77): Offers no generational balance; modern tickets prioritize younger running mates
3. Out of office 18+ months: By 2028 campaign season, he'll have been a private citizen since January 2027, losing political infrastructure, fundraising networks, and media relevance
4. Zero shortlist mentions: Comprehensive political insider reporting shows no consideration whatsoever
5. Superior alternatives: Shapiro (PA) and Whitmer (MI) offer younger, active Midwestern governors if regional balance is needed
6. Market consensus: 0.15% implied probability with high volume (12,873) and open interest (12,623) indicates sophisticated money agrees this is near-impossible

Positive factors (slight probability boost):

1. Wisconsin swing state value: Evers led a critical battleground state
2. Strong approval ratings: Maintained >50% approval during tenure
3. Non-zero probability: Politics occasionally produces surprises; cannot assign absolute zero

Step 3: Scenario Construction

The only conceivable paths to "Yes" require breaking multiple historical precedents simultaneously. Even in bull case scenarios, the probability remains infinitesimal.

Step 4: Final Probability Estimate

Starting from base rate of ~0.2%, I apply modest downward adjustment based on:

• Explicit retirement decision (not forced out)
• Complete absence from insider speculation
• Market efficiency on high-volume contract

Final estimate: 0.08% (0.0008)

This is slightly lower than the current market price of 0.15% (0.0015), suggesting the market may be very slightly overpricing this outcome, though both figures round to "essentially impossible."

Step 5: Edge Assessment

The market at 0.15% vs my estimate of 0.08% represents a potential edge, but it's minimal in absolute terms. At these extreme tail probabilities, transaction costs and opportunity cost of capital matter significantly. The edge exists but is likely not exploitable profitably.

There is a theoretical edge here - my estimate of 0.08% vs market price of 0.15% represents the market being roughly 2x too high. However, this edge is NOT practically exploitable for several reasons:

1. Absolute scale: The difference is 0.07 percentage points (7 basis points). Even if correct, the profit potential is minimal relative to capital lockup until November 2028.

2. Transaction costs: At bid/ask spread of 0.001/0.002, you're paying 100% spread to enter and exit. This dwarfs any theoretical edge.

3. Opportunity cost: Capital would be locked up for 2+ years for a maximum gain of ~0.92 cents per dollar deployed (if buying "No" at 0.998).

4. Tail risk modeling: At extreme probabilities (sub-1%), small modeling errors matter enormously. The difference between 0.05% and 0.15% is real but my confidence interval spans this range.

5. Market efficiency note: The high volume (12,873) and open interest (12,623) suggest this market has been well-explored by other bettors. The 0.15% price likely reflects consensus among informed participants.

VERDICT: Edge exists but is not actionable. Both my estimate (0.08%) and market price (0.15%) effectively round to "essentially impossible." This is a correctly priced market where the outcome is near-certain (No) but the market maintains a small probability for black swan scenarios. No recommended bet.
