Today’s crypto news to know
Strategy nears all-time Bitcoin holding record after US$75.7 million purchase
Michael Saylor’s Strategy (NASDAQ:MSTR) acquired 950 BTC for US$75.7 million between September 14 and September 20, paying an average price of US$79,670 per coin inclusive of fees.
An 8-K filing on Monday revealed the purchase, bringing the firm’s total treasury to 846,000 BTC acquired for US$63.80 billion. Saylor also confirmed the purchase in a separate X post.
The new acquisition places Strategy within 1,363 coins of its all-time record holding of 847,363 BTC recorded on June 22.
Strategy rebuilt its stash over the last two months after summer sales reduced its holdings to 840,447 BTC in early August.
The company spent more than double its Bitcoin outlay on preferred stock, deploying US$174 million to repurchase 1,771,238 STRC preferred shares.
Strategy funded both transactions directly through its USD Cash pool, drawing down the balance to US$1.05 billion. The company sold zero common stock under its at-the-market offering program during the reporting period.
Bitcoin Surges Past US$85,000
Bitcoin surged 5.7 percent over 24 hours to reach US$85,111 on Monday (September 21) following a turbulent week of macroeconomic decisions.
The asset absorbed a Federal Reserve interest rate hike, a Bank of Japan rate hike to a 31-year high, and the Senate’s rejection of the Clarity Act without trading meaningfully below US$75,000.
Easing macroeconomic pressures propelled the rally as Brent crude hit a half-month low and US 10-year Treasury yields fell to 4.93 percent. Short sellers have suffered massive losses as crypto short liquidations approach US$850 million over 24 hours.
Spot buying cleared resistance at US$82,000 and forced more than US$230 million in Bitcoin shorts to liquidate as secondary stop-loss orders pushed the price through US$84,000. Spot Bitcoin ETFs finished the week with US$6.2 million in net inflows after reclaiming US$592 million across Thursday and Friday to erase earlier weekly losses.
In its latest analysis on X, trading resource The Kobeissi Letter described crypto as being “in a new bull market”, but Bitfinex Alpha noted that continued BTC gains rely on buyer support, growing open interest and new inflows into US spot Bitcoin ETFs.
Investors now look towards the upcoming Personal Consumption Expenditures (PCE) report on September 30 and the October 2 jobs report as the next price catalysts.
WSJ: CEO allegedly ignored US$10 million fraud attempt
The Commodity Futures Trading Commission (CFTC) opened an investigation into Polymarket following a US$10 million stolen-card fraud attempt on its US platform in February, according to a report by the Wall Street Journal.
Criminals attached thousands of stolen debit cards to Polymarket accounts to place bets and route proceeds to separate accounts under their control. Payment processor Checkout.com flagged more than 80 percent of incoming deposits as fraudulent at the peak of the attack, far above the 1 percent industry average.
CEO Shayne Coplan allegedly instructed employees to “just keep growing and pay a fine if regulators ever find out” when staff escalated fraud concerns. Company leadership eliminated a safeguard mandating that users withdraw money to their original deposit method to clear a backlog of withdrawal requests. ]
A company spokesperson stated that Polymarket’s “market integrity framework includes processes to detect, review and respond to suspicious activity” and noted that fraud rates normalized by May.
The CFTC probe coincides with Polymarket raising US$1 billion at a US$21 billion valuation, including a US$300 million investment from Donald Trump Jr.’s 1789 Capital fund.
