Analysis

This market estimates a 35% likelihood that Valve will remove at least one map from its competitive pool by June 30, 2026. The current probability reflects limited recent map removals from Valve's active rotation, as the company typically maintains stability in the map pool to preserve competitive integrity and player investment. The main factors pushing this probability upward are community feedback on underperforming maps, balance issues, or technical problems that could necessitate removal. The biggest uncertainty revolves around Valve's map management philosophy and whether any pending balance patches or competitive season changes might trigger a removal decision. A scheduled competitive season update or announcement from Valve about map pool changes would directly resolve much of this uncertainty. Current trading volume remains relatively low, suggesting limited conviction across traders.

  • Valve has not removed maps from the active competitive pool in recent seasons, suggesting institutional resistance to removal outside extraordinary circumstances
  • Community sentiment and pro-player feedback on specific maps directly influence Valve's curation decisions
  • Scheduled competitive season patches or map pool announcements between now and June 30 would be the primary catalyst for resolution clarity
  • Technical exploits, balance issues, or performance problems with existing maps could trigger emergency removal
  • Valve's historical track record shows preference for iterative balance changes over map removal as a policy response

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
