Contrarian October-hike trader tetrose held 297,800 Yes contracts as the market faded him

October hike bet remained in place

Trader tetrose held about 297,800 Yes contracts on a 25-basis-point Federal Reserve rate hike in October even as the market priced that outcome below the trader’s average entry level, according to TradingView’s Binance News report.

The report cited TradingBeats monitoring from October 10, when the implied probability of that outcome on Polymarket was about 15.5%. Tetrose’s previously established position had an average entry price corresponding to about 23.42%.

At the reported valuation, the contracts were worth about $46,200, with an unrealized loss of about $23,600. The figures describe the October 10 snapshot, rather than an updated position as of this article’s October 14, 2026 publication.

BTC and equity shorts added exposure

Tetrose also held short positions in BTC and the S&P 500 index on Hyperliquid, according to BlockBeats On-chain Detection, as cited in the TradingView report.

After being stopped out the previous day, the trader reopened a short of about 20.95 BTC. That position had a notional value of about $1.73 million and an unrealized loss of about $6,491.

The S&P 500 index short was worth about $2.71 million and carried an unrealized loss of about $1,666. The report put the combined notional value of the two shorts at about $4.45 million.

What it means for prediction markets

• The position was against prevailing pricing: The market’s roughly 15.5% implied probability was below tetrose’s average entry level of about 23.42%.
• The loss was not final: The reported $23,600 prediction-market loss was unrealized; the snapshot does not establish a sale or settlement.
• Other positions provide context, not proof of intent: The BTC and S&P 500 shorts show additional exposure, but the reporting does not establish whether they were explicitly linked to the rate-hike bet.
• Timing matters: The holdings and valuations were reported for October 10 and should not be treated as live October 14 figures.
