AION 2 leads the listed contenders

AION 2 was priced at 31% in Kalshi’s Steam weekly top-seller market, compared with 9% for Planet Zoo 2, in the Oct 14, 2026 snapshot published at 12:39 PM ET. The contract closes Oct. 19 and had recorded $33K in trading.

What it means for prediction markets

• A lead is not a majority probability: AION 2’s 31% price puts it ahead of Planet Zoo 2 at 9%, but does not indicate that traders consider an AION 2 win more likely than all alternatives combined.
• Volume and odds measure different things: The Steam contract’s $33K in trading reflects activity, not certainty about the result.
• Settlement details remain important: The supplied material identifies an Oct. 19 close but does not specify the Steam ranking window or settlement rules. Those details are necessary to interpret precisely what outcome the contract measures.
