Spot ETH ETF inflows hit $633M, but $10K prediction market remains flat

Spot ETH ETF inflows reached $633M over the past 10 days, and the Polymarket contract for Ethereum reaching $10,000 by December 31, 2026, sits at 4% YES, unchanged over the past week.

The inflows have generated optimism among traders, and a separate market for Ethereum reaching $4,000 by April 30 is seeing increased interest, though exact odds remain undisclosed. The flat 4% on the longer-term contract suggests that ETF demand alone hasn’t shifted expectations for a move to $10,000.

The long-term market is thin. Daily face value is $694, with $28 in actual USDC traded. It takes $1,029 to move the odds by 5 percentage points, meaning a single large trade could meaningfully shift the price. The lack of movement despite $633M in ETF inflows points to traders waiting for additional catalysts before repricing.

The $633M inflow is a positive signal for Ethereum, but it hasn’t moved the prediction market. A YES outcome on Ethereum reaching $10,000 by year-end pays a 25x return, and traders appear to need more than ETF flows to bet on that. Successful testnet upgrades or regulatory clarifications could be the kind of developments that change the calculus.

Watch for announcements from Ethereum co-founder Vitalik Buterin and SEC Chair Gary Gensler, along with any macroeconomic shifts or institutional moves that could affect Ethereum positioning.
