Will government spending decrease by $750B before 2028?

Step-by-step Analysis:

1. Resolution Criteria Clarity: The bet requires a $750 billion absolute decrease in government spending from Q4 2024 to Q4 2028. This is an extraordinarily high bar - representing approximately 10% of current federal outlays ($7.4 trillion in 2026).

2. Structural Budget Composition (Fatal Obstacle):

• Mandatory spending (Social Security, Medicare, Medicaid) constitutes ~60% of federal budget and is legally protected from executive cuts without Congressional legislation
• Net interest payments are contractually obligated and growing rapidly (3.2% GDP in 2025 → 4.6% projected by 2036)
• Only ~30% of budget (discretionary spending) is theoretically accessible to cuts

3. Mathematical Feasibility: To achieve a $750 billion net reduction by Q4 2028:

• Trump administration proposed $163 billion in non-defense discretionary cuts, offset by $119 billion defense increase = net $44 billion
• Even if ALL non-defense discretionary spending (~$900 billion annually) were eliminated entirely, and defense held flat, this would only reach ~$900 billion over 4 years
• But mandatory spending and net interest continue growing structurally, requiring even deeper cuts elsewhere to offset

4. Congressional Reality Check (Evidence from March 2026):

• January 2026: Republican-controlled Congress reversed most proposed Trump cuts
• Restored NIH, Education, housing funding
• Increased Pentagon budget to $839 billion (above White House request)
• This demonstrates even a friendly Congress will not support cuts at this scale

5. CBO Trajectory (Contradicts Bet Resolution):

• February 2026 CBO revised 10-year deficits upward by $1.4 trillion
• 2025 reconciliation package added $4.7 trillion to debt (partially offset by $3.0 trillion tariff revenue)
• Federal outlays at 23.3% of GDP, above 50-year average - trending up, not down

6. Historical Base Rate:

• Zero precedent for absolute spending reductions of this magnitude in modern U.S. history
• Even post-WWII demobilization and 1990s budget balancing saw spending grow in absolute terms
• Inflation alone (CPI ~2.4% YoY) creates ~$180 billion annual nominal increase pressure

7. Market Movement Context:

• Recent 3pp move (4¢ → 7¢) attributed to "low liquidity and political rhetoric around reconciliation 2.0 and impoundment threats"
• Not driven by fundamental fiscal policy changes
• Market may be overreacting to noise rather than signal

8. Impoundment Authority (Legal Uncertainty):

• Trump administration reportedly exploring unilateral spending withholding
• Impoundment Control Act (1974) prohibits this
• Historical precedent: courts blocked Nixon-era impoundment attempts
• Even if successful, temporary withholding ≠ permanent spending reduction for resolution purposes

9. Time Horizon (1.75 years into 4-year term):

• Already 1.75 years elapsed (Q4 2024 → March 2026)
• Spending has increased, not decreased
• Would need ~$750 billion cut over remaining 2.75 years = average $273 billion/year net reduction
• Current trajectory shows opposite direction

10. Synthesis: Every fundamental indicator points to spending expansion, not contraction:

• CBO upward deficit revisions
• Mandatory spending growth
• Net interest explosion
• Congressional resistance to cuts
• Structural budget constraints

The 4-7% market probability appears inflated relative to fundamental fiscal reality. My estimate of 1% reflects:

• ~0.5% tail risk of catastrophic economic collapse forcing emergency cuts
• ~0.5% tail risk of unforeseen black swan event (major war ending, entitlement reform miracle)
• Effectively zero probability under normal political/economic scenarios

STRONG NEGATIVE EDGE: Market overpriced at 4-7%.

My estimated probability is 1% versus current market price of 4-7% (using midpoint ~5.5%), suggesting the market is 5.5x overpriced.

Edge Justification:

1. Fundamental Mismatch: All structural fiscal indicators point to spending expansion, not the $750 billion contraction required for resolution. CBO projects upward deficit revisions, mandatory spending is growing, and net interest costs are exploding.

2. Recent Price Movement is Noise: The research explicitly notes the recent 3pp move (4¢→7¢) is "likely driven by low liquidity and political rhetoric around reconciliation 2.0 and impoundment threats, not fundamental fiscal changes." This suggests uninformed trading creating temporary mispricing.

3. Congressional Evidence: January 2026 Congressional reversal of proposed cuts provides concrete real-world evidence that even Republican-controlled Congress will not support cuts at the required scale. This is a binding constraint the market is underweighting.

4. Mathematical Impossibility: To achieve $750B reduction requires cutting ~35% of all discretionary spending over 4 years while mandatory spending grows. The Trump administration's own budget proposal shows net cuts of only $44 billion - 1/17th of the required scale.

5. Base Rate Anchoring: Market may be anchored on political rhetoric rather than historical precedent. Zero instances of cuts at this magnitude in modern U.S. history.

Trading Recommendation: SELL / SHORT at current 4-7% levels. Fair value is approximately 1%, implying 4-6% of edge. The market appears to be confusing political theater (impoundment threats, DOGE announcements) with actual fiscal policy implementation. Recent price movement strengthens the edge as the market has moved AWAY from fundamental value.

Risk Management: Position size should account for low liquidity (wide bid-ask spreads) and tail risk of black swan fiscal crisis (~1% scenario). Duration to resolution (3 years) creates uncertainty, but structural constraints are so binding that confidence remains high even with long time horizon.

Market has been relatively stable in the last 24 hours (currently 7¢). 7-day range: 4¢ – 7¢. In the last hour alone, the market moved up 3.0pp — suggesting active repricing.
