DigitalBridge announced a final close for DigitalBridge Partners III at $11.7 billion in total commitments, including fund and related LP co-investment vehicles. The close positions the firm as the largest dedicated digital infrastructure manager by fund size, doubling the $5.8 billion raised for DBP II in 2020. The fund began deploying capital in early 2023 and has already committed roughly $4 billion across twelve portfolio companies, primarily in fiber, tower, and hyperscale data center assets across North America and Europe.
The co-investment structure is not standard. DigitalBridge structured parallel vehicles allowing anchor LPs to write larger checks directly into individual deals alongside the main fund, a mechanism that became common in real estate but rare in infrastructure until recently. The firm did not disclose the split between fund commitments and co-investment pledges, but three people familiar with the raise said co-investment accounts for roughly 30-35% of the total, suggesting the core fund is near $7.5-8 billion. That structure matters because it gives DigitalBridge the ability to move on $1-2 billion single-asset deals without syndicating to outside capital or burning through fund capacity on one transaction.
The timing is deliberate. AI training clusters are pushing power and cooling requirements per rack to 40-80 kilowatts, roughly four times the density of traditional cloud workloads. Hyperscalers are pre-leasing data center capacity 18-24 months before construction completes, and wholesale colocation providers are selling out inventory before buildings are topped out. DigitalBridge has committed capital to Vantage Data Centers, which operates 30+ campuses globally, and recently acquired a controlling stake in Switch, the Nevada-based operator with Tier IV-certified facilities in Reno and Las Vegas. Switch's modular design allows rack density scaling without full campus rebuilds, a feature that matters as model sizes and training runs continue to expand.
The LP base tilted institutional. Public pensions, sovereign wealth funds, and insurance allocators accounted for more than 70% of commitments, according to two investors in the fund. That mix reflects a broader shift: institutional LPs are treating digital infrastructure as a separate sleeve from traditional infrastructure or real estate, with distinct return and volatility profiles. Data center assets levered at 50-60% LTV with 12-15 year hyperscaler leases are generating unlevered yields in the 7-9% range, with rent escalators tied to power cost pass-throughs and CPI adjustments. That compares favorably to core real estate at 5-6% yields with higher lease rollover risk.
Operators should watch three follow-on events. First, DigitalBridge is expected to announce at least two new platform investments in edge data centers or fiber-to-the-premises networks before year-end 2025, according to one investor briefed on pipeline activity. Second, the firm is likely to raise a continuation fund or secondary process for DBP II assets in 2026-2027, allowing early LPs to roll gains and new LPs to access seasoned assets at a step-up. Third, debt markets for data center construction loans are tightening as regional banks pull back from project finance; DigitalBridge's ability to self-finance through fund equity and co-investment may create a selection advantage in competitive auctions.
Switch's Reno facilities are already running at 95% committed capacity. Vantage is breaking ground on four new campuses in Northern Virginia and Phoenix with expected delivery in late 2026. The co-investment pledges are not optional capital.
