Billionaire one-time wealth tax on California ballot?

How to read the numbers

Implied / market-implied YES

The probability of YES implied by current traded prices (mid or last). It is what participants are paying for, not a claim about real-world odds.

Model estimate

A rule-based heuristic from the signal engine when a rule sets one, not a black-box forecast. Some signals only describe liquidity or spreads and may show no model estimate.

Edge / gap

The difference between the model estimate and market-implied, in percentage points (model minus market for YES). Filters may use “largest gap.” This is informational only-not trading advice or guaranteed advantage.

Stance (above / below / near estimate)

Compares market-implied to the model estimate when both exist. Labels are not buy or sell recommendations.

Confidence

A simple UI clarity label for signals (not a prediction). It summarizes the signal’s own magnitude/quality metrics into one of: Low, Mid-low, Mid, Mid-high, or High.

Volume

Reported trading activity for the market, for context on size and liquidity.

Change & sparklines

Movement in market-implied YES over the window labeled on the card-often 24h where data allows.

Signals

Rule-based flags from ingested public data. They are not trade recommendations.

This market will resolve to "Yes" if a ballot initiative is certified to appear on the official statewide California ballot for the November 3, 2026 election, that proposes a one-time tax targeting individuals, households, or family units with wealth, assets, or net worth of at least $1 billion (USD or equivalent), by June 25, 2026, 11:59 PM ET (the official cutoff date for new initiatives to be approved). Otherwise, this market will resolve to "No". Certification means the initiative is officially approved by the California Secretary of State for a statewide ballot. The primary resolution source will be official information from the government of California. If unavailable, a consensus of credible reporting may be used.
