Divergent Analyst Views Fuel Volatility for SoftBank Shares

SoftBank shares surged 12% as bullish and bearish analysts clash over its massive $30B OpenAI commitment and strong quarterly earnings, highlighting a pivotal investment dilemma.

The investment case for SoftBank Group Corp. has become a tale of two starkly different narratives, a tension thrown into sharp relief by a single day's trading. On Wednesday, the company's shares surged by more than 12%, a dramatic move triggered by conflicting assessments from major financial institutions.

A Clash of Research Perspectives

The recent divide was highlighted by opposing initiations from two prominent firms. On March 9, Cantor Fitzgerald commenced coverage with a bullish "Overweight" rating, setting a price target of 6,100 yen. The analysts pointed to SoftBank's leadership in semiconductor intellectual property and its diversified investment portfolio as key strengths.

This optimistic stance was directly challenged by Jefferies. The bank downgraded SoftBank to "Underperform" and slashed its price target from 5,118 yen to 3,140 yen. Its central concern revolves around SoftBank's deepening financial commitments to OpenAI, which Jefferies argues threatens valuation integrity and creates structural risk due to concentrated exposure.

Jefferies notes that SoftBank supplied approximately 85% of the capital raised in OpenAI's recent funding rounds. This involvement, the firm suggests, has been a primary driver behind OpenAI's valuation skyrocketing from $150 billion to $840 billion, simultaneously inflating SoftBank's own net asset value.

The $30 Billion OpenAI Commitment

The scale of this bet is substantial. On February 27, 2026, SoftBank entered a binding agreement to commit an additional $30 billion via its Vision Fund 2 to an OpenAI financing round. Upon completion, SoftBank's cumulative stake in the AI leader would reach $64.6 billion, representing an ownership interest of roughly 13%.

The financing for this move is initially expected to come from bridge loans and other debt, later to be replaced by existing assets. This very obligation prompted S&P Global Ratings to revise its outlook on SoftBank to "negative" in March 2026, citing potential pressure on the group's financial flexibility.

Jefferies did outline a scenario that could cause it to reassess: if OpenAI achieves a public listing at a valuation exceeding its recent private funding rounds, or if other investors make substantial commitments, thereby diluting SoftBank's role as the dominant financier.

Strong Quarterly Results Provide Support

Amid the strategic debate, SoftBank's recent operational performance offered bulls some concrete data. The quarterly results released on February 12 showed earnings per share of $0.14, surpassing the consensus estimate of $0.10. Revenue of $12.90 billion also exceeded forecasts of $12.44 billion. The company reported a net margin of 48.62% and a return on equity of 23.66%.

Beyond its OpenAI investment, SoftBank is advancing tangible AI infrastructure projects. The company is planning a 10-gigawatt data center on a former U.S. Department of Energy uranium enrichment site in Ohio, powered by natural gas plants valued at around $33 billion. The official announcement of the site's redevelopment was made jointly by SoftBank and the U.S. Department of Energy on March 20, 2026.

The market's volatile reaction underscores the pendulum swing between two competing visions: one of a profitable corporation with ambitious AI-driven growth, and another of a increasingly leveraged entity whose valuation is heavily tied to the fortunes of a single, unlisted company.
