Bitcoin jumped briefly on Tuesday after a post on the US markets regulator's X account (formerly Twitter) said it had approved so-called exchange-traded funds (ETFs) in the cryptocurrency.
The Securities and Exchange Commission (SEC) later deleted the post and said its account had been "compromised".
Bitcoin jumped to almost $48,000 immediately after the erroneous post before falling back to around $46,000.
US regulators are expected to make an announcement on the new ETFs this week.
The false post appeared on the SEC's official X account shortly after 16:00 Washington time (21:00 GMT).
It said the regulator "grants approval for #Bitcoin ETFs for listing on all registered national securities exchanges".
The post was immediately picked up and quoted by social media users and business news outlets.
Within minutes the SEC's chair Gary Gensler posted a message refuting the erroneous announcement on his personal X account: "The @SECGov twitter account was compromised, and an unauthorized tweet was posted. The SEC has not approved the listing and trading of spot bitcoin exchange-traded products."
Investors are hotly anticipating an SEC announcement on the potential approval of spot bitcoin ETFs, which is expected this week.
It would mark a key milestone for the cryptocurrency market in gaining acceptance to mainstream financial markets.
Several asset management firms have applied for SEC approval for spot bitcoin ETFs.
ETFs are portfolios that allow investors to bet on multiple assets, without having to buy any themselves.
Traded on stock exchanges like shares, their value depends on how the overall portfolio performs in real time.
Some ETFs already contain Bitcoin indirectly - but a spot Bitcoin ETF will buy the cryptocurrency directly, "on the spot", at its current price, throughout the day.
