SoftBank

What SoftBank does

SoftBank Group Corp. is a Tokyo-listed Japanese strategic investment holding company (TYO:9984) founded by Masayoshi Son in 1981, operating across five reporting segments: Investment Business of Holding Companies, SoftBank Vision Funds, SoftBank (telecom and digital services), AI Computing, and Others. The group controls core operating assets including a ~90% stake in Arm Holdings (semiconductor IP and chip design), wholly-owned Ampere Computing (Arm-based AI CPUs acquired for $6.5B in November 2025), Graphcore (AI accelerators), SoftBank Corp. (Japanese mobile/broadband), PayPay (mobile payments, Nasdaq-listed March 2026), LINE Yahoo (internet/e-commerce), and SB Energy (solar and data center developer). The SoftBank Vision Funds (SVF1, SVF2) and Latin America Fund deploy capital into AI-focused growth companies globally, with cumulative OpenAI exposure reaching ~$65B (over 20% of NAV).

SoftBank's technology stack spans semiconductor IP and chip design through Arm, AI compute via Ampere and Graphcore, large-scale AI infrastructure through the $500B Stargate JV with OpenAI and Oracle (targeting 7GW over four years, with an 800-acre Abilene, Texas complex), AI services delivered through the SB OAI Japan joint venture (including Patching as a Service cybersecurity launched June 2026 and Cristal intelligence), and next-generation robotics via SoftBank Robotics plus the pending $5.4B ABB robotics division acquisition. Core proprietary capabilities include the new Arm AGI CPU (March 2026), the Physical AI Plant concept, and energy infrastructure (SB Energy operates 2,130 MW of solar capacity with 1,180 MW under construction).

The business model combines recurring subscription revenue from Japanese telecom and PayPay (subscription, transaction fees), licensing royalties from Arm's IP business and Ampere/Graphcore chip sales to hyperscalers, capital gains and dividends from strategic equity holdings (Arm, OpenAI, T-Mobile, Intel), fair-value revaluations from the Vision Funds, managed services revenue from AI cybersecurity offerings, and energy/data center operations revenue from SB Energy. FY2025 consolidated operating revenue reached ¥7,038.7 billion (record high, up 7.6% YoY) with net profit of ¥550.8 billion (also a record). GTM channels include SoftBank Corp.'s direct enterprise sales force and consumer stores, PayPay's self-serve app distribution, Arm's global OEM/embedded IP licensing, and a dedicated SB OAI Japan cybersecurity sales team scaling toward 1,000 specialists targeting Japan's top 3,000 critical infrastructure operators.

Expansion highlights7 records

Direct peers

• Berkshire Hathaway: Diversified strategic holding company with a large equity investment portfolio and wholly-owned operating subsidiaries; most direct analog to SoftBank Group's holding-company + operating-subsidiary + investment-fund hybrid model.
• Naspers / Prosus: Global internet and technology investment holding company with controlling stakes in listed and private tech assets (e.g., Tencent historically); directly comparable to SoftBank's Vision Fund-style growth-stage tech investment thesis.
• Tencent Holdings: Chinese tech conglomerate combining social, gaming, payments and cloud with a deep strategic investment portfolio in global tech; comparable in scale, diversification and ability to deploy patient capital across AI-adjacent sectors.
• CK Hutchison Holdings: Hong Kong-based diversified conglomerate with telecom, retail, infrastructure and tech investment operations; mirrors SoftBank's combination of telecom subsidiaries (SoftBank Corp.) and global investment activities.
• Reliance Industries: Indian conglomerate combining traditional businesses (energy, retail, telecom) with aggressive AI and digital investments (Jio Platforms); similar conglomerate scale, capital deployment intensity and AI-forward strategic pivot.

Broad incumbents

• Alphabet (Google): Hyperscaler using Arm Neoverse V2-based custom silicon (Google Axion) and an AI compute customer of SoftBank's ecosystem; competes with Stargate-class infrastructure buildouts and is a parallel AI platform incumbent.
• Microsoft Corporation: Co-investor in OpenAI alongside SoftBank and a Stargate JV partner via Azure; deploys Arm-based custom silicon (Cobalt) at scale and is the most direct US hyperscaler counterpart to SoftBank's AI compute strategy.
• Saudi Public Investment Fund (PIF): Sovereign wealth fund deploying tens of billions into AI and tech (e.g., backing Lucid, multiple AI startups); broadly comparable patient-capital AI thesis to SoftBank Vision Funds but on a sovereign balance sheet.

Others

• Mubadala Investment Company: Abu Dhabi sovereign investor with significant AI, semiconductor and global tech holdings; comparable as a long-horizon capital pool that competes with Vision Funds for late-stage AI deals.

Emerging players

• Nvidia Corporation: Strategic supplier and financial guarantor of OpenAI's lease obligations and SB Energy's Stargate project financing; functionally a critical infrastructure partner to SoftBank's AI compute buildout, though it operates a fundamentally different business model.
