Bitcoin (BTC)

CoinGape.com reports that Polymarket US has filed with the Commodity Futures Trading Commission to list Bitcoin, Ethereum and Solana price contracts. This regulatory move follows the acquisition of QCEX, which allows Polymarket to re-enter the US market. QCEX self-certified a new set of crypto price event contracts under federal regulations, clearing the path for listings as soon as August 28.
These products are binary options where traders bet on whether an asset’s price will trade above or below a specific level at a given time. Unlike leveraged perpetual futures, the contracts are fully collateralized $1 instruments that settle using CF Benchmarks data rather than a single exchange print. Bitcoin recently fell below $78K due to hot PCE inflation data but recovered to reclaim $80,000 with a 2% jump and 5% volume increase.
BlackRock’s digital assets head Robert Mitchnick stated that “Bitcoin’s macro case is strengthening with growing US debt and fiscal concerns.” Ethereum also rose 3% to $2,505 with a 24% volume surge, while Solana surpassed $100 after a 7% jump. Polymarket participants currently believe Ethereum will not dip to $1,750 again this year.
How the market reacted
Whalio's own Binance spot order flow for BTC, measured when this story was written up on 27 August 2026. Not the outlet's figures.
Bitcoin is trading at $79,023.75 with a 1-hour buy ratio of 45.5% and a 4-hour buy ratio of 47.1%, both below the 24-hour ratio of 49.9%. This indicates that buying pressure is fading in the short term compared to the daily average. The 1-hour volume delta is -$4,442,654 and the 4-hour delta is -$19,235,282, showing net selling activity. The 24-hour volume delta is -$903,088, confirming that sellers are currently outweighing buyers on a daily scale. A negative volume delta means that more volume is occurring on sell-side trades than buy-side trades. Despite this, spot volume remains high at $1,148,236,056 with over 4.2 million trades.
The latest daily buy ratio of 46.7% sits at the 18th percentile of the last 322 days, against a median of 49.2% - weaker buying than most days.
Twenty-four hours later
What BTC did over the 24 hours after the story broke. The market moves for its own reasons; this is what happened, not what the story caused.
Was that an ordinary day?
The same Binance spot measurements for BTC, averaged over the days leading up to the story.
Over the preceding week, the buy ratio averaged 51.6%, making today’s 24-hour ratio of 49.9% slightly below the weekly norm by 1.7 points. Volume is currently at 0.54x the weekly average, indicating a quieter trading day than usual. The coin has gained 14.0% over the past eight days, with a total volume delta of +$445,688,281. While today shows net selling, the broader week has been defined by strong net buying across six of seven days. This suggests that recent short-term selling is occurring within a broader weekly uptrend.
