Tracks the leading outcome in a winner-take-all prediction market set with 10 outcomes.

Why this matters:
Markets currently price an 91% chance that the Federal Reserve's balance sheet exceeds $6.2 trillion by December 30, 2026. The Fed's balance sheet size depends primarily on two forces: the trajectory of asset purchases or quantitative easing programs, and ongoing redemptions of maturing securities. If the Fed maintains its current policy stance or shifts toward accommodation, the balance sheet would likely expand beyond $6.2 trillion. Conversely, sustained monetary tightening or accelerated runoff would constrain growth. The probability gradient across contracts (91% at $6.2T down to 79% at $6.6T) reflects uncertainty about the magnitude of expansion. Key resolution points include Federal Open Market Committee decisions throughout 2026 and actual balance sheet data releases each week, which will clarify whether the Fed is purchasing assets or allowing its holdings to naturally mature and roll off.

Key factors:
- Current Fed balance sheet is approximately $5.4 trillion (as of mid-2026); reaching $6.2 trillion requires ~14% growth over six months
- Fed policy rate trajectory and inflation data between now and year-end will determine whether the central bank pursues asset purchases or continued runoff
- Weekly balance sheet releases provide real-time measurement; significant deviations from current trend would shift probabilities materially
- Geopolitical or financial-stability shocks could trigger emergency liquidity operations that accelerate balance sheet expansion
- Maturity redemptions and reinvestment decisions by the Fed directly mechanically affect total assets held

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.

## SF Signal

- SF Index, regime, and 30d Brier calibration are computed separately and surfaced at https://simplefunctions.dev/admin/calibration.
