The prediction market landscape is quietly shifting beneath the surface. Opinion Labs is processing $1.5B in weekly volume with virtually no mainstream coverage, while Polymarket dominates the crypto discourse with $1.8B in comparable traffic. Both platforms show similar growth trajectories, yet only one has announced tokenomics. What's really interesting: the arbitrage plays. Points farmers are cycling roughly $50K weekly through both ecosystems, capturing an estimated $2.5K in expected value at conservative conversion assumptions. That's the kind of efficiency gap you typically see before market maturation hits. The Arbitrum ecosystem plays a quiet supporting role here—infrastructure that works, protocols that scale. Worth watching how this dynamic evolves once liquidity fragments further.
