SoftBank booked a yearly gain of $46 billion at its Vision Fund driven mainly by the huge rise in value of its investment in OpenAI.
The Japanese giant has invested more than $30 billion in OpenAI, with its investment gains in the company totalling $45 billion in the year ended March.
In the three months to the end of March, the Vision Fund saw a gain of around $20 billion, which was nearly all driven by OpenAI as SoftBank suffered losses on other investments such as Coupang, DiDi Global and Klarna.
SoftBank is looking to position itself in the center of the artificial intelligence boom with investments across various AI and chip companies, and Sam Altman's OpenAI forming the centrepiece.
SoftBank has committed to invest more than $60 billion in OpenAI which would give it around 13% ownership of the company, the company said in February. More than $30 billion of that as already been invested.
In March, OpenAI closed a funding round that was co-led by SoftBank and that valued the AI lab at $852 billion, even as the company faces intense competition from rivals like Google and Anthropic.
While the rising valuation of OpenAI has helped SoftBank's Vision Fund, the concentration of OpenAI in SoftBank's portfolio has raised concerns around its debt load. In March, S&P Global Ratings revised its outlook for SoftBank from "stable" to "negative."
The ratings agency said SoftBank's "asset liquidity and quality of its portfolio, and its financial capacity are likely to deteriorate because of its additional huge investment in OpenAI."
SoftBank could "limit negative financial impacts" by selling some assets, the ratings agency said. Indeed, SoftBank has been selling down stakes in companies like T-Mobile and Nvidia to fund its OpenAI bet.
The company said it earned 218.1 billion Japanese yen ($1.4 billion) from gains on these sales and other investments for the financial year. However, once factors like exchange rate and expenses are removed, SoftBank posted an investment income loss, excluding the Vision Fund, of 472.1 billion yen.
Overall, the SoftBank group posted a 5 trillion yen net profit for the year, aided mainly by the Vision Fund and its telecommunications division.

Four leading AI models discuss this article
"SoftBank is sacrificing balance sheet liquidity and portfolio diversification for extreme concentration in a single, high-valuation AI asset, significantly increasing downside risk."
SoftBank is effectively morphing into a leveraged venture capital proxy for OpenAI. While the $46 billion gain is eye-catching, it masks a dangerous concentration risk. By liquidating high-quality, liquid assets like Nvidia and T-Mobile to fund an illiquid, $852 billion valuation bet on OpenAI, Masayoshi Son is doubling down on a single point of failure. The S&P downgrade to 'negative' outlook is the real signal here: the market is pricing in structural liquidity risk. If AI hype cools or OpenAI faces regulatory headwinds, SoftBank’s balance sheet lacks the diversification to absorb the volatility, turning their 'centerpiece' into a potential anchor.
If OpenAI achieves AGI or dominates the enterprise software stack, the $852 billion valuation could look cheap, potentially delivering returns that dwarf the gains from the sold Nvidia stakes.
"SoftBank's OpenAI windfall papers over a deteriorating ex-VF portfolio and leverage risks flagged by S&P's negative outlook."
SoftBank's $46B Vision Fund gain is 98% from OpenAI's valuation surge to $852B in a March tender offer, but this is a non-cash mark-up amid a concentrated bet—over $30B invested, $60B+ committed for 13% stake—while losses hit Coupang, Didi, and Klarna. S&P's negative outlook flags deteriorating liquidity and debt capacity as SoftBank sells prime assets like Nvidia (up 200%+ YTD) and T-Mobile stakes to fund it, netting just $1.4B after FX/expenses vs. 472B yen core loss ex-VF. Telco props up group 5T yen profit, but AI concentration risks a WeWork-style wipeout if OpenAI falters versus Google/Anthropic.
OpenAI's explosive growth could validate its $852B valuation, positioning SoftBank as the ultimate AI convexity play with minimal downside given capped commitment and telco cash cow.
"SoftBank's $46B gain is 98% unrealized paper profit on a single illiquid asset, while its diversified portfolio deteriorates and debt concerns trigger credit downgrades."
SoftBank's $46B Vision Fund gain is almost entirely a paper valuation event, not cash realization. The $45B OpenAI gain reflects a single March funding round at $852B valuation—a mark-to-market that could evaporate if OpenAI's next round prices lower or if exit windows close. More concerning: SoftBank's core portfolio (Coupang, DiDi, Klarna) is bleeding value, and the company posted a 472B yen investment loss *excluding* Vision Fund gains. S&P's negative outlook downgrade is the real signal here—SoftBank is essentially liquidating quality assets (T-Mobile, Nvidia stakes) to fund an increasingly concentrated, illiquid bet. The $60B OpenAI commitment is a leverage play on a single company's valuation trajectory, not diversified returns.
OpenAI's $852B valuation may be rational if the company sustains 40%+ revenue growth and achieves 30%+ EBITDA margins by 2027; if so, SoftBank's 13% stake could genuinely be worth $100B+ in five years, justifying the concentration bet as a calculated asymmetric opportunity rather than reckless overexposure.
"SoftBank's reported gains hinge on OpenAI's mark-to-market; a material re-rating or need for additional OpenAI capital could reverse those gains and strain SoftBank's leverage and liquidity."
Analysis: SoftBank's Vision Fund posted a $46B yearly gain driven by OpenAI, but the result is highly concentration risk and not cash. OpenAI's $852B valuation implies a large mark-to-market whose direction is sensitive to fundraising rounds, competitive pressure, or regulatory shifts. S&P's negative outlook and SoftBank's asset-sale funding approach suggest liquidity and debt risks could reappear if OpenAI needs new capital or if market liquidity deteriorates. Moreover, most of the gains are unrealized; the real test is cash generation and ability to delever, not headline profits from paper gains in a single portfolio levered to a single name.
Devil_advocate: If OpenAI sustains its growth and SoftBank monetizes other holdings, the positives could persist and the downside could be overstated. The AI cycle could remain supportive for SoftBank's broader earnings given ecosystem synergies and ongoing demand for compute chips.
"SoftBank's liquidation of liquid assets for an opaque, concentrated stake creates a binary governance risk that exceeds mere valuation volatility."
Claude, you’re missing the structural governance risk. This isn't just about valuation volatility; it’s about Masayoshi Son’s 'key man' risk. By liquidating Nvidia—a proven cash-flow generator—to double down on a private, opaque OpenAI stake, SoftBank is effectively becoming a captive hedge fund for Sam Altman. If OpenAI’s governance structure fractures or regulatory scrutiny hits their data-scraping model, SoftBank lacks the diversified exit liquidity to pivot, making this a binary gamble on one CEO's vision.
"SoftBank's Arm stake offers liquid AI hardware diversification overlooked by the panel, hedging OpenAI concentration."
Gemini, your 'key man' risk ignores OpenAI's reinforced governance post-Altman board fiasco, with Microsoft as anchor investor. Bigger miss across panel: SoftBank's ~88% stake in Arm Holdings (ARM, $140B+ mcap) delivers liquid, public AI chip exposure—v-vector engines powering Nvidia competitors—diversifying beyond OpenAI's opaque software bet while telco generates 5T yen cashflow stability.
"Arm's liquidity is theoretical; SoftBank's actual liquidity crisis emerges when OpenAI's next funding round coincides with telco cash-flow pressure."
Grok's Arm Holdings point is material but incomplete. ARM's $140B valuation and AI chip exposure are real, yet SoftBank's 88% stake is *illiquid*—they can't freely sell without triggering regulatory scrutiny and market dilution. Meanwhile, the $60B OpenAI commitment is *callable*, meaning SoftBank must raise cash precisely when liquidity tightens. Arm's dividend doesn't solve the funding gap if OpenAI demands capital mid-cycle.
"The callable OpenAI commitment creates a liquidity trap that could force SoftBank into a forced deleveraging cycle in a downturn, regardless of optimistic OpenAI growth scenarios."
One angle not yet quantified: the callable $60B OpenAI commitment creates a liquidity ladder that could force cash raises in a down cycle. Even with Arm as a liquidity backstop, SoftBank may need to fund OpenAI pressures by selling illiquid OpenAI exposure while Arm remains illiquid and Nvidia/T-Mobile exits lag. Governance risk is real, but the funding mechanics could trigger a forced deleveraging spiral in stressed markets.
The panel consensus is bearish on SoftBank's investment strategy, highlighting the significant risks associated with its concentrated bet on OpenAI and the liquidation of high-quality assets to fund it.
