Pronóstico: Will Microstrategy announce a Bitcoin purchase June 23-29?

Platform comparison

Market context

MicroStrategy has bought 4,980 Bitcoin between 23 and 29 June at an average price of $106,801, yet the Polymarket contract for a June 23–29 announcement still prices the event at just 7% YES[1][6]. This low implied probability reflects the market’s focus on the timing of the public disclosure rather than the purchase itself, since the market resolves only if an official announcement falls within the window[1]. On Polymarket, traders use USDC on the Polygon network to buy conditional tokens; if the announcement occurs, each “Yes” share pays $1, otherwise it pays zero[2].

Historically, MicroStrategy has disclosed purchases promptly via Form 8-K filings, as seen in its recent $43 million acquisition of 535 BTC on 23 June[3]. The company has bought Bitcoin for six straight weeks, accumulating $45 billion in total holdings, and Michael Saylor has reiterated that adding Bitcoin remains central to shareholder value[4]. Yet announcements can lag by days if the filing is delayed or if the company opts to bundle disclosures, which explains why the crowd-implied probability remains low despite the confirmed purchase[3].

Traders should watch for an official Form 8-K filing from MicroStrategy or a statement from Michael Saylor before the settlement deadline of 30 June 2026[1][3]. The company typically uses regulated US exchanges like Coinbase and employs a simple algorithm to avoid market impact, meaning announcements may be subtle or delayed[4]. A recent Barron’s report confirms the 4,980 BTC purchase but does not yet confirm the announcement date, leaving the 7% probability as a reflection of that uncertainty[6].
