Beyond the headline players: How KIA, OIA, and Mumtalakat divide the labor

Kuwait’s sovereign wealth fund manages more than USD 1 tn, and you would be hard pressed to name a single thing it bought last year. That opacity — which some interpret as a sign the Kuwait Investment Authority (KIA) is part of the region’s supporting cast of sovereign wealth funds — is deliberate: A 1982 law bars the fund from disclosing its holdings to the public. The result is that pool of capital that rivals Abu Dhabi’s Adia barely registers in the GCC’s loud media environment.

KIA is often reflexively bundled with Oman’s OIA and Bahrain’s Mumtalakat, also known as the Gulf funds that aren’t PIF, Mubadala, Adia — or the recently-formed L’Imad. The bundling is where the analysis usually gets the picture wrong, according to analysts we spoke with. These three funds have little in common beyond geography and a shared taste for staying out of the news. What lumps them together — a rough size bracket beneath the majors — hides how differently each one is wired. Look at their mandates rather than their balance sheets and a genuine division of labor comes into view.

“Every Gulf country manages its public wealth and finances differently,” Diego Lopez, founder and managing director of Global SWF, tells EnterpriseAM. Oman and Kuwait, in his reading, “follow the ‘Saudi approach,’ where OIA and KIA play different mandates under the same umbrella fund” — a single institution running several distinct pots. Bahrain went the other way, splitting the job across “different funds for different purposes: FGR for stabilization purposes, and Mumtalakat for local development and holding the stakes in national champions.”

KIA is the fund that’s least flattered by the bundling: “KIA is a mega-fund with USD 1 tn+ in AUM, but we don’t hear that much about their investments because these are usually done via funds, without disclosure requirements,” Lopez says. While KIA has been operating in incognito mode, it’s spent the past year anchoring some of the biggest transactions in the market. In June 2025, KIA was the first non-founder financial anchor to join the USD 30 bn AI Infrastructure Partnership founded by MGX, BlackRock, Global Infrastructure Partners, and Microsoft. It went on to anchor Brookfield’s USD 10 bn AI infrastructure vehicle and to join KKR, NVIDIA, and Vistra as a founding investor in Helix Digital Infrastructure.

There’s a job for everyone

Is real strategy taking shape across these funds, or is it just one opportunistic move after another? "Both, depending on the altitude," says Roy Conners, Gulf sovereign wealth fund analyst, speaking in a personal capacity. “At the deal level, coordination remains largely transaction-specific. The megafunds supply scale and platform creation. The funds are developing distinct and complementary roles: KIA as the region’s great external allocator and anchor LP, OIA as a domestic transition vehicle with a ring-fenced savings arm, Mumtalakat as an operating holding company that partners for capital and expertise.”

That specialization is why the funds keep turning up in one another’s deals. The co-investment “is the connective tissue of that specialization, not evidence of incoherence,” Conners says. When Mumtalakat teams up with Abu Dhabi’s CYVN on McLaren or with M42 on healthcare, it’s putting operating assets and a home-market listing venue on the table in return for capital and know-how. “The map is emerging through repeated bilateral deals rather than through any formal GCC-level mechanism,” Conners adds, “which is consistent with how institutions in the region have typically been built.”

“We are seeing a more sophisticated and intentional investment landscape emerge across the GCC,” says Julie Kassab, sovereign wealth fund leader at Deloitte Middle East, who frames it as “the evolution of Gulf SWFs from traditional capital allocators into strategic transformation engines.”

Size doesn’t always matter most: “Scale is an advantage, but it’s not the only factor that determines influence … What may appear modest in one market can represent a significant investment and meaningful impact in another,” Kassab says.

The stabilization worry has it backwards

The thesis that these funds could act as “stabilization” funds to backstop fiscal deficits is fundamentally off. Chatter suggests that a Gulf country facing a budget deficit (ahem, Bahrain) is likely to tap into its sovereign wealth fund to plug fiscal holes and consequently hollow out the intergenerational mandate they were built on, but Conners argues that this framing does not fully reflect how the funds are structured. “The framing assumes these are all savings funds drifting into something else, and that is not the architecture,” he says.

How the money is structured proves that framing is off. Kuwait runs two pillars on purpose: A General Reserve Fund built to finance the state, and a ring-fenced Future Generations Fund that does the long-term saving. Oman is set up along the same lines, pairing a domestic National Development Fund with an international Future Generations Fund. Bahrain divides the work too — “FGR plays the stabilization and savings function, whereas Mumtalakat is the strategic investment arm,” Lopez says. Across all three, stabilization was handed to a designated pocket from the outset. “In these cases, the stabilization function generally reflects the institutional design rather than necessarily indicating mandate erosion,” Conners tells us.

And it’s a role that’s reserved for a handful of funds. “Not all funds in the Gulf can or will act as stabilization buffers,” Lopez says. “Historically, these have been only Adia, KIA, SAMA, OIA and FGR.”

The more useful questions are whether the plumbing is holding up and “whether transfers between the pillars stay rule-based and transparent,” Conners says. On that score, Kuwait has tightened the taps: Lopez notes the fiscal rules “were modified a few years ago to allow transfers between funds only in years of surplus,” and the government has since reopened debt markets with a KWD 30 bn (USD 65 bn) borrowing ceiling and tenors up to 50 years, giving itself a financing route that spares the savings.

Not exactly a league table

A reflexive assumption is that the smaller funds simply follow where PIF and Mubadala lead, but that only holds if they’re all chasing the same assets on the same terms, which they aren’t. “Their currency is not check size but position,” Conners says. For OIA, that position is access to Oman’s domestic transition, and a fund that posted a 14.6% return and USD 7.5 bn in profit in 2025 is no frontier curiosity. For Mumtalakat, it’s a stable of national champions — Alba, Beyon — sitting under a record BHD 592.7 mn net income. “Describing them as price-takers may overlook the fact that they often pursue different mandates, assets and partnership structures from the largest regional funds,” Conners says. “They are not.”

No one drew this up as a master plan, but there is a map taking shape. “Sovereign capital in the region is becoming a network,” Conners says, “and in a network the interesting question is not who is biggest, but where each institution adds distinctive value to particular transactions.” Bahrain has made itself an operating venue, Kuwait the anchor allocator, Oman the transition play.

What to watch for next:

• KIA’s next platform commitments will show whether a manager-led fund can keep buying its way to the front of the queue in AI and digital infrastructure, or whether the anchor terms thin out as every sovereign crowds into the same trade.
• OIA’s divestment and IPO activity is the truer gauge of its domestic strategy: Stake sales and listings are what turn concentrated local holdings back into recycled capital, and a thin pipeline would lay bare the concentration risk its bulls prefer to wave away.
• And if oil softens, Kuwait’s General Reserve Fund is the one to watch — a drawdown that reaches the ring-fenced Future Generations Fund would tell the region that stabilization-by-design has met its limit.
