SUI ETFs hit 12 consecutive weeks of positive inflows, accumulating $9.3 million in shares

Twelve weeks without a single net outflow. That’s the streak SUI spot ETFs have managed to string together, accumulating a combined 9.3 million SUI tokens across three US-listed products as of late August 2026.

The three products in question, Canary Capital’s SUIS, 21Shares’ TSUI, and Grayscale’s GSUI, have each attracted capital at varying rates, but the overarching trend is the same: investors keep buying.

The numbers behind the streak

Glassnode data from August 21 shows daily net flows of +521 SUI for TSUI and +687 SUI for GSUI on that particular session. SUIS logged zero net flow for that specific day, suggesting its inflows have been more episodic rather than continuous on a daily basis.

The 9.3 million figure represents dollar-denominated share purchases that give investors exposure equivalent to actual SUI tokens.

From launch day jitters to institutional staple

All three spot SUI ETFs officially began trading on February 18, 2026, after clearing the regulatory gauntlet that had previously only been navigated by Bitcoin and Ethereum products. SUIS traded approximately 1,468 shares on its first day. GSUI managed around 8,000.

The path to these products was cleared in part by earlier experimentation. A leveraged 2x SUI ETF from 21Shares, ticker TXXS, was approved and listed back in December 2025, two months before the spot versions arrived.

Canary Capital has also added staking features to its SUIS product, allowing the fund to generate yield on the underlying SUI tokens.

What the streak means for the broader ETF landscape

Cumulative spot crypto ETF inflows have surpassed $140 billion since early 2024, a figure dominated by Bitcoin and Ethereum products.

One thing the data does not yet show is a clear, direct link between ETF inflows and SUI’s spot price performance. The research context notes that concrete analyses linking sustained inflows to specific price movements remain sparse.
