The Week in Review

Democrats won control of both the House and the Senate in Tuesday's midterm elections, with BTC trading between roughly $76,500 and $77,800 on Election Day and spot Bitcoin ETFs posted a third straight day of outflows. BTC dipped below $76,000 as results came in overnight before reversing on Wednesday, rising as much as 4.2% to just over $81,000 as U.S. stocks rallied and oil fell on hopes of an end to the Iran war, with roughly $378M of short positions liquidated within an hour. Wednesday was the only session of the week with net inflows into spot Bitcoin ETFs, at $74.6M.

However, sentiment shifted on Thursday, when the Nasdaq Composite fell 5.52% as chipmakers led a selloff driven in part by concerns that the new Democratic majorities could slow AI data center construction, alongside weak forecasts from Qualcomm and Arm. BTC fell from near $80,900 overnight to about $75,600 that afternoon, and ETH fell more than 6%. CME FedWatch odds of a December hike dropped from 83% on Wednesday to 67% as tech stocks sold off, before Friday's October payrolls rose 165,000 against a 65,000 consensus, with August and September revised up a combined 84,000, pushing odds back up to 76.8%. BTC slipped to $74,900 later on Friday, as spot Bitcoin ETFs finished the week with $1.28B of net outflows, including $412M on Friday. The same day, the U.S. Treasury issued a FinCEN order cutting exchange MEXC off from the U.S. financial system. The selling resumed on Sunday evening, when BTC fell from about $75,600 to $73,510 in ten minutes, its lowest level since August, and total crypto liquidations topped $1.15B over 24 hours. BTC finished down ~4% at $75k, ETH ~6% lower, the alt basket down ~5%, gold ~3% higher, and the S&P 0.8% lower.

 

Market Pulse

Flow gauges fell further this week while positioning gauges cooled, with altcoin breadth the one exception. Funding eased from +9.4% to +6.6% annualized but held in the high range, while open interest slipped from 2.6% to 2.5% of total market cap, back into the low range. ETF flows fell from -$0.3B to -$2B, near the bottom of their one-year range, and Stablecoin Supply change fell from -$4.6B to -$4.8B, a fifth straight week of net contraction that leaves it near its one-year low. Onchain yield eased from 3.9% to 3.8%. 45 of the top 100 altcoins beat Bitcoin, up from 33 the week prior, moving back into the neutral range.

 

Chart of the Week: Prediction Markets Outgrow the Election Cycle

Kalshi and Polymarket traded a combined $5.9B during the week of the 2026 midterms, 7.7x the $0.77B they traded during the week of the 2024 presidential election. Even eight weeks before the midterms, the platforms combined weekly volume was $3.9B, already roughly five times 2024's election week. While volumes have clearly skyrocketed, the more impactful trend is how the election barely impacted the prediction markets’ weekly volumes. Election-week volume ran 14% above the prior four-week average in 2026, versus 121% in 2024.

Both platforms are now less reliant on a single event or trend for high volumes. In October and November 2024, political markets made up 90% of Kalshi's volume and 65% of Polymarket's, and Kalshi had yet to list sports contracts. Sports contracts made up 78% of prediction market trading in October, while political markets made up less than 3% of Kalshi's volume and less than 27% of Polymarket’s volume in every month of 2026.The venue mix has also flipped since 2024. Polymarket accounted for 67% of combined volume in the week of the presidential election, while Kalshi took 77% in the week of the midterms.
