When I visited Computex, Ayar Labs treated SIVE not as something they rely on exclusively, but more as one option among several.
I still haven’t seen any third-party or authoritative data showing that SIVE is superior to its competitors.
Key takeaways on TSMC's next-generation advanced packaging, CoPoS (publicly available technical details omitted):
1. CoPoS is currently expected to enter mass production in 2H28. It is designed to improve the economics of ultra-large packages above the 9.5x reticle-size class, with NVIDIA’s Feynman AI chip a potential first adopter.
2. According to industry checks, glass is used in two distinct places (dimensions in mm):
→ 310 x 310 temporary glass carriers
→ 250 x 250 (pilot) / 510 x 515 (mass production) glass panels, processed and later cut into individual glass core substrates
3. The glass core substrate is essentially a three-layer structure: a glass core sandwiched between ABF (ABF-GCP) build-up layers on both sides. The widely discussed glass processing challenges, such as TGV formation and copper filling / metallization, are tied to this part of the stack.
4. Common misconceptions about CoPoS:
→ ❌ Misconception 1: CoPoS uses a glass interposer. ⭕️ Correction: The glass is not an interposer. The interconnect role is instead handled by the chip-side RDL, plus the TGV/Cu interconnects and ABF build-up layers in the glass-core substrate stack.
→ ❌ Misconception 2: Glass replaces ABF. ⭕️ Correction: As the substrate architecture above shows, glass and ABF coexist.
→ ❌ Misconception 3: Chips sit directly on glass. ⭕️ Correction: Chips are attached to the ABF build-up surface of the glass core substrate.
5. CoPoS should extend and reinforce TSMC’s leadership in advanced packaging, potentially giving that advantage visibility through around 2032.
What an incredible week at #COMPUTEX2026! Ayar Labs and Wiwynn were proud to showcase our optically-connected rack.
It was great connecting with industry leaders and collaborating with our ecosystem partners. Together, we are marking a step forward for AI scale-up architectures.
Tragedy in Sofia, Bulgaria. Vasko Filipov, known as Tyson from the notorious Kalashnitsite crime group, was racing friends through the city when his luxury car crashed into a public bus at over 150 km/h. The bus overturned, killing three passengers and injuring dozen😭
🚨 CONFIRMED via Finansinspektionen (Swedish FSA): JPMorgan Chase & Co. just crossed the 5% ownership threshold in $SIVE.
Official filing:
→ Holder: JPMorgan Chase & Co.
→ Transaction date: June 2, 2026 (same day as the GlobalFoundries announcement)
→ Reason for flagging: "Köp" (BUY)
→ Pre-transaction position: 0 shares
→ Post-transaction position: 16,098,583 shares / 5.25008% of total voting rights
Position structure:
→ J.P. Morgan Securities plc (UK entity): 15,916,852 voting rights — 5.19%
→ J.P. Morgan Securities LLC (US entity): 181,731 voting rights — 0.06%
→ Direct shares: 10,049,558 (3.14% of total shares)
→ Cash-settled instruments (likely swaps): 6,049,025 share equivalents
Why this is structurally significant:
Swedish law requires mandatory disclosure when crossing the 5% ownership threshold. JPMorgan went from ZERO to 5.25% on June 2. The flagging reason filed with the FSA was explicitly "Köp" (Buy) — not custody, not market-making inventory. This is a deliberate institutional position.
The timing is what makes it remarkable:
June 2 was the same day GlobalFoundries announced the silicon photonics reference design partnership and $SIVE moved +50-70%.
Three possible reads:
JPM was positioned beforehand and captured the move
JPM built the position aggressively into and after the news.
JPM is positioning ahead of the Nasdaq NY listing in an underwriter / placement agent role
All three are bullish. The third would be the most strategically significant — tier-1 US investment banks don't take 5% positions in Swedish micro-caps without strategic context.
Connecting back to the "zero institutional ownership" post earlier this week:
Five days ago: $SIVE had zero US institutional 13F filings.
Today: the world's largest investment bank discloses a 5%+ position triggered by a "Buy" transaction.
The institutional layer that was missing has started forming.
The composition tells you it's sophisticated:
6 million of the 16 million share-equivalents are in cash-settled derivatives. The rest is direct shares. This is the kind of structured position you set up when you're a major capital markets player preparing for a multi-event sequence — index inclusions, dual listing, sector rotation.
JPMorgan doesn't take 5% positions in $2-3B Swedish micro-caps because they're bored.
$SIVE just got its first major Wall Street institutional anchor.
