Massive $1.8M MSTR Call Options Sweep Signals Bullish Bitcoin Play

Today, a substantial $1.8 million call option position in MSTR signaled a highly bullish bet. If held to expiry, investors seek a significant appreciation above $450 by September 19, 2025. The moderate volume-to-open-interest ratio of 26% suggests fresh institutional interest rather than overwhelming speculative activity. The sweep execution of this trade indicates urgency in getting the position filled at prevailing market prices.

With MSTR currently trading at $390.25, the buyer needs approximately 15% upside movement just to reach the strike price. An additional appreciation to overcome the substantial $36.08 premium paid per contract will also be required to bear fruit from this position. The three-month timeframe provides reasonable duration for the bullish thesis to materialize. Though, the significant out-of-the-money positioning suggests expectations of major positive catalysts or continued momentum in MicroStrategy’s Bitcoin-leveraged business model.

Volume and Open Interest Data

From June 6th to June 10th, there was a notable rise in both volume and open interest for the MSTR $450 strike call expiring on September 19, 2025. This steady rise signals fresh bullish activity. On June 6th, volume hit 530 contracts with a slight dip in open interest (-24), suggesting some closing or intraday trading. However, momentum picked up significantly on June 9th with 839 contracts traded and OI rising by 340, confirming new positioning. The trend intensified further on June 10th, where volume spiked to 1,253 contracts and open interest jumped +733, reflecting strong conviction from new buyers.

This surge in volume and open interest suggests that institutions or informed traders are establishing long call positions rather than closing them out. This is especially evident given the consistent positive OI change over the last two days. Further supporting this is the rise in contract price from $30.31 to $36.90, followed by a slight pullback to $35.40. This pattern implies traders were willing to pay a premium to gain upside exposure. Overall, this pattern indicates growing bullish sentiment and long-term positioning on MSTR.

Trade Side Distribution

The trade side distribution chart for the MSTR $450 call expiring on September 19, 2025 reveals a dominant bullish bias in the flow. A striking 77% of the total premium—$1.8 million—was executed above the ask, which is an extremely aggressive buy signal. These types of orders suggest urgency and high conviction from buyers, typically indicating that participants are willing to pay more than the ask price to secure their positions. In contrast, only 23% of the premium, or $534.8K, was executed at the bid, often considered less bullish or even indicative of selling pressure.

There were no trades executed at the ask, mid, or below, further emphasizing the dominance of aggressive call buying. This distribution supports the narrative of strong bullish sentiment and institutional accumulation, with traders expecting substantial upside in MSTR and demonstrating a willingness to commit premium to gain exposure.

What's Happening with MicroStrategy

MicroStrategy, now operating under the name Strategy, has continued its aggressive Bitcoin acquisition strategy in 2025. Recently, the company purchased an additional 1,045 BTC for $110 million, bringing its total holdings to over 580,000 BTC. These acquisitions have been funded through various financial instruments, including equity sales and preferred stock offerings.

This strategy has significantly impacted MicroStrategy’s stock performance. The company’s share price has surged by 400% this year, largely due to its substantial Bitcoin holdings. The correlation between MicroStrategy’s stock and Bitcoin’s price has strengthened over time. Currently, the correlation coefficient stands at 0.77 year-to-date. The correlation reached as high as 0.92 since the end of 2020.

While this approach has attracted investors seeking exposure to Bitcoin through traditional equity markets, it also introduces significant volatility and risk. As Bitcoin’s price fluctuates, so does MicroStrategy’s stock, making it a high-risk, high-reward investment. Despite these risks, MicroStrategy remains committed to its Bitcoin-centric strategy, positioning itself as a leading corporate holder of the cryptocurrency. 

About MicroStrategy

MicroStrategy is a publicly traded enterprise software company best known for its business intelligence (BI) platform, which helps organizations analyze data to make informed decisions. Its core product offers powerful tools for data analytics, dashboard creation, and reporting, catering to large enterprises across industries.

In recent years, however, MicroStrategy has gained widespread attention for its strategic pivot into Bitcoin. Under the leadership of Executive Chairman Michael Saylor, the company has become one of the largest corporate holders of Bitcoin, using it as a primary treasury reserve asset. This dual identity—enterprise analytics provider and Bitcoin proxy—has made MicroStrategy a unique and closely watched player in both the tech and crypto markets.

Analyst Ratings

The analyst sentiment for MicroStrategy (MSTR) appears mixed and polarized based on the most recent updates. Notably, Market Edge gives the stock a “Long” rating, and LSEG (London Stock Exchange Group) rates it “Outperform”, both indicating positive forward expectations. On the bearish end, Schwab Equity Ratings assigns MSTR an “F” grade, its lowest rating, suggesting poor fundamentals or risk concerns. Meanwhile, CFRA, Argus, and Morningstar have either neutral stances or have not issued updated evaluations.

This divergence underscores the controversial nature of MicroStrategy’s investment thesis, which blends traditional enterprise software with aggressive Bitcoin exposure. Bulls see upside potential through Bitcoin and business growth, while bears flag volatility and balance sheet risk.
