Bitcoin, Ethereum open interest up $2B each amid US-Iran tensions

Bitcoin and Ethereum open interest surged by over $2 billion each. The likelihood of Bitcoin reaching $100,000 by year-end sits at 34.5% YES on Polymarket, slightly down from 36% just a day ago.

Market reaction

The Bitcoin $100,000 market is stable at 34.5%, with a minor dip from 36% over 24 hours. The Bitcoin $150,000 market is at 9.5%, up from 9% yesterday. The open interest spike during ongoing US-Iran tensions suggests traders are more willing to take on risk, but the prediction market odds have barely moved in response.

Why it matters

Overall market volume remains modest, with $3,490 in actual USDC traded over the past day. The $100,000 market requires $2,908 to move prices by five points, a reasonable level of liquidity. The $150,000 market is much thinner: only $792 can shift it by the same margin, making it vulnerable to large individual trades.

The open interest increase doesn’t guarantee a price rally. At 34.5¢, a YES share for Bitcoin reaching $100,000 by December 31 pays $1, a 2.9x return. To justify this bet, you’d need to believe a significant catalyst (favorable regulatory developments, macroeconomic shifts) arrives within the next eight months.

What to watch

MicroStrategy and ARK Invest are the key actors here. Any substantial Bitcoin acquisitions or ETF approvals could shift the odds. SEC updates and geopolitical developments tied to US-Iran tensions are the other variables worth tracking.
