Bitcoin Drops 11% Ahead of Anthropic IPO: Is History Repeating the SpaceX Sell-Off?
Bitcoin (BTC USD) has fallen 11.3% since October 20, and crypto analyst Benjamin Cowen suggested on Wednesday that the upcoming Anthropic IPO may be one reason. His chart shows Bitcoin tracking almost the same path it took before SpaceX went public in June.
Perhaps the reason Bitcoin is falling (if you need one) is due to the upcoming Anthropic IPO.

Investors often sell other assets to free up cash for a big IPO, Cowen argued. Anthropic is expected to raise up to $64.4 billion when its shares start trading, likely on November 19. That would make it the second-largest IPO ever, after SpaceX’s $75 billion.
Bitcoin trades at $73,612 on Binance, down 1% in 24 hours, after this week’s hot inflation report pushed the odds of a Federal Reserve rate hike close to certain.
So is the Anthropic IPO pulling money out of Bitcoin, or is the Fed the bigger weight? We checked both.
Bitcoin’s Slide Matches the SpaceX Run-Up, Until June 1
We rebuilt Cowen’s comparison from Binance’s daily closing prices. Day zero is the first day of trading: June 12 for SpaceX and, if the expected date holds, November 19 for Anthropic.
The two paths are close for the first three weeks. Twelve days before SpaceX listed, Bitcoin was down 7.1% from the start of the window. Twelve days before Anthropic’s expected debut, on November 7, it was down 8.6%.
Then the SpaceX path dropped hard. BTC USD fell another 12% in four days in early June and was down 19.5% at the point where it is down 11.3% today. It ended the 30 days before the SpaceX IPO 19.8% lower.
That drop had other causes too. U.S. spot Bitcoin ETFs had 13 straight days of net outflows from May 15 to June 3, the longest streak since they launched. Strategy sold Bitcoin for the first time in four years, and rising oil prices pushed inflation fears higher. About $1.86 billion in crypto bets were forcibly closed in one day.

BTC USD Fell Before Only 5 of 9 Big IPOs
One match is not a pattern. So we checked how Bitcoin traded in the 30 days before and after nine big IPOs since 2019, from Uber to SpaceX.
BTC USD fell before five of them and rose before four. The median move in the 30 days before the listing was a 3.6% drop. In the 30 days after, Bitcoin rose seven times out of nine, with a median gain of 5%.
Size may matter. The two largest IPOs, SpaceX and Saudi Aramco’s $25.6 billion listing in 2019, both came after Bitcoin fell more than 17% in a month. Rivian, the third largest at $11.9 billion, came after a 16.5% rise. Two cases are too few to call it a rule, but Anthropic would be the second-biggest test yet.

Rate-Hike Odds Barely Moved During the Slide
The Fed theory has a timing problem. Traders were already betting on a December rate hike before Bitcoin started falling.
On Polymarket, the combined odds of a December hike stood at 80.2% on October 20. They dipped to 65.1% on November 6 and were back at 80.0% on Tuesday morning, before the inflation report. Over that time, BTC USD fell about 9%.
The odds moved only on Tuesday. October’s consumer prices rose faster than expected, and the chance of a hike jumped to 97.4%, including 11.9% for a half-point move. Bitcoin dropped to $72,727 that day, its lowest price since August 20. The rate news explains Tuesday’s drop, not the whole month.
Tech stocks fit the slide better. Since October 20, the Nasdaq has fallen 4% and Nvidia 20.8%. Bitcoin has traded closely with tech stocks this year, and the Crypto Fear & Greed Index sits at 29, in “fear”.
So the answer is probably “a bit of each”. An IPO this size needs buyers, and some growth investors may be selling Bitcoin to make room. But the IPO record is mixed, the Fed odds did not change until Tuesday, and the sell-off in tech stocks lines up with Bitcoin’s drop.
BTC USD Price Analysis: Can Bitcoin Hold $72,727?
BTC USD trades at $73,612, down 1% in 24 hours and about 6% over the past week. On the daily chart, where each candle covers one day, it sits below both of its exponential moving averages (EMAs), averages that give recent prices more weight. The 50-day EMA stands at $78,890 and the 200-day EMA at $76,447.
- Resistance: $75,599, Monday’s high, then $76,447, the 200-day EMA. Above that, $78,890, the 50-day EMA.
- Support: $73,510, the November 8 low, then $72,727, Tuesday’s low. Below that, $68,902, the August 20 low.

| Path | What has to happen | Next stop |
|---|---|---|
| Push higher | A daily close above the 200-day EMA at $76,447 | $78,890, the 50-day EMA |
| Stall | Bitcoin holds between $72,727 and $76,447 into the IPO | A range until ANT trades |
| Slip | A daily close below $72,727 | $68,902, the August 20 low |
If the SpaceX pattern holds, the selling should ease once ANT starts trading: Bitcoin was flat in the 30 days after SpaceX listed. Until then, $72,727 is the level to watch.
