Polymarket is starting to roll back the 'free-for-growth' model: Starting February 18, market orders on sports markets (NCAA, Serie A) will have fees, while limit orders remain free with rebates. What’s more critical is that sports markets already account for nearly 40% of activity. If they fully expand this, the revenue curve will immediately shift; And once they can consistently generate revenue data, whether it’s valuation narratives or token/airdrop expectations, it’ll naturally drive itself forward.
